Seto Izumi

Seto Izumi, (true name Aegis Vimnea), is an 18-year-old Altairian male raised on Earth, and the primary protagonist of 'Chronicle of Rebellion'. He is an artificially created being made from the DNA of an Altairian royal and the Astrum of Void Shoarus, the father to Hiroki Izumi, and the husband of Yue Izumi. Created to serve Shoarus' objective of consuming all existence with the void dimension known as the Omnia, Seto was exiled from Asteria, the Altairian home planet, after his mother Cordelia was transformed into the Goddess of Ruin through Shoarus' influence. Unknowing of his true purpose, Seto was sent to Earth by Cordelia's husband 'Asphodel', and taken in by Mizuko Izumi and Tatsuo Itoshi, Mizuko raising him to eventually become one of totality's greatest defenders. He constantly strives to help others in need, which has kept the universe and beyond safe from destruction on multiple occasions.
=== Appearance ===
Seto's appearance has changed a fair amount since his conception, starting off with black-colored, spiky hair and hazel-colored eyes. As his journey went on, and he dealt further damage to his physical body, his looks have changed a significant amount. However, there are a few constants. The spiked hair and his eye color have remained a constant through all of his base forms throughout the years, alongside his facial features, which he obtains mainly from Asphodel's human appearance. However, he has softer eyes, a kind demeanor, and a lighter-pale skin complexion from his mother's human form. His current appearance combines many of the elements of his past ones, creating a definitive look for him. Currently, in most situations, Seto wears an orange jacket with blue hemlines over a black-colored t-shirt, with black colored pants and light brown shoes. Alongside this, despite it no longer being over his neck, Seto still carries the scarf given to him by Akira Yamamoto. It resides under his right sleeve wrapped around the entirety of his arm from the wrist up.
=== Personality ===
Seto is caring and emotional, never hesitating to help or rescue someone in danger, even if he knows that he might not be strong or otherwise qualified enough to do it. Often, he does this on instinct, taking a more careless approach than the usual overthinking he goes through. Seto putting others' lives above his own can go to the extreme, to the point where he has little to no sense of self-preservation.
Whether it is his business or not, he is renowned for offering assistance to or lecturing those who are experiencing personal or emotional difficulties. Although first perceived by some as confusing or even irrational, this brazen attitude is also recognized by many and has won him the loyalty, appreciation, and admiration of individuals who were before antagonistic towards him. In addition, Seto has a sympathetic side and has grown to wish to comprehend the people he has encountered in order to maybe save them from themselves. He is not naïve in this belief and will use force if necessary, but he genuinely wants to reach out and assist people in healing and self-reform.
Seto has a heart of gold and rarely, if ever, feels anything negative. Because of his intense loyalty to his friends and family, he is fiercely protective of them. He is a man of his word and will always honor his promises. His goals are fairly straightforward; he merely searches for new adventures. He has a very pragmatic and easygoing outlook on life. At the same time, he exhibits such unshakeable determination and tenacity to succeed, constantly resolute to never give up in the face of any adversity.
It has been noticed numerous times that Seto has a unique impact on people. His sincere love of individuals and his appreciation of life in its purest form has the power to change people for their better, even converting some of his adversaries into allies. Seto's straightforward approach to communication, combined with his direct and casual manner, frequent acceptance of things as they are, and tendency to take things at face value, Seto can be fairly blunt when he expresses himself. Despite this, Seto is exceptionally adept at applying himself whenever motivated. He is able to comprehend a problem quickly and also comprehend the fundamentals of whatever that gets put forward to him, if not perfect it.
Seto had started to behave very differently after his struggle against Bahamut Luciver had ended, and the struggle against Elysia, or the Unalter, had begun. After the Luciver battle's tragedy, witnessing numerous innocent people have their lives taken, and many lives absolutely destroyed by the state of the world, discovering why he was the target of assault by higher beings so frequently, and having to look out for his companions, Seto grew colder and more detached from other people.
He rushed into battles and left behind all of the people watching out for him so that no one else would get wounded because of the enormous stress and pressure. His disrespect for his own physical well-being reached an all-time high, and he neglected to take care of his basic needs like eating and sleeping. After his friends miraculously got through to him and took him back in, these traits seem to have diminished for the most part.
He is also shown to have atychiphobia, the fear of failure, even now.
=== Background ===
==== Prelude ====
A young Altairian arrives on an Earth with technology 500 years more advanced than the standard, taking the form of a young human boy on the side of a road, sitting down in front of a comic store and just crying his eyes out.Every human in this world is reliant on technology for almost every necessity. Most paid no mind to the boy, apart from one woman: Mizuko Izumi. The young woman would take the boy in, and learn of the fact he had no one to take care of him anymore. So she took up the responsibility of raising him. She would also give him a name, not learning of the one he was already given. The young Altairian was now called 'Seto'.
Mere weeks earlier, as a result of the Diaboli beginning to seep out into the human world, a young demon emerged (about 7 in human years), and was also taken in by Mizuko. He was given the name 'Ankoku'. Seto and Ankoku would meet. However, his existence was to be kept a secret from Mizuko’s current fiancee, a biologist named Tatsuo Itoshi, the CEO of ORIGIN, one of the world’s largest scientific research organizations. 
Tatsuo was a man with a kind-hearted soul and an incredible love for science, the arts, and history. He shared this feeling with his new son for years to come after his arrival in Seto's life, and the two bonded fairly well. Tatsuo taught the curious Seto many things about human history. However, Seto obviously wasn't the only one with curiosity. Tatsuo knew something was off about him, and began scraping skin cells off of him in his sleep to analyze them. With his advanced technology, Itoshi discovered Seto's Altairian origin and the many capabilities they had, including the ability to change their DNA freely with fractions of Sparklinen, many abilities that would become essential to Seto's survival in the future.
Following Seto’s adoption, the governments of the world began to unfairly defund ORIGIN. Tatsuo lost fame, fortune, and his employees, leaving him almost alone in his efforts… This caused him to get desperate, forcing Seto out of Mizuko’s hands one day and beginning to conduct tests on the child to extract as much DNA as possible, stealing large portions of his blood as well as multiple non-vital organs, and utilizing his results to create a cure for all mortal diseases using a specific property of Altairian blood which serves to make them immune to not just those diseases, but any and all disease in general.
This was an act of kindness to the world, yes, but at the cost of his son’s own well-being. He presented it to the UN, and got funding to mass-produce this cure, as well as a Nobel Peace Prize. Seto was basically used as a cure factory for YEARS to come. Anytime he was close to death, Itoshi would revive him. Anytime he was hungry or thirsty, he was given only enough to survive. Itoshi had become obsessed with the notoriety and monetary gain he gained from the world stage, and continued to use Seto’s Altairian genetics to further his disgusting methods, leaving the poor boy, now 8 in human years, permanently traumatized.
However, Mizuko would eventually confront him. This led to genuine disaster. Mizuko was used as a test subject for one of the many experimental versions of the newfound cure, mutating her into some kind of disgusting amalgamation of flesh and elongated bones. The Diaboli feeds off of human suffering... and the malice felt by Vesyn would finally show itself to this unfortunate broken family. Bahamut Luciver, the King of the Diaboli would manifest within Mizuko's body, laughing maniacally as he attacked Tatsuo, leaving him severely wounded and bleeding out. This gave Seto and Ankoku a chance to escape, which they took. Ankoku was forced back into the Diaboli via Luciver’s influence, and Seto was left on his own, running from ORIGIN officials for almost an entire year.
Seto was left on the streets while running away. Starving, dehydrated, and in utter pain. One fateful day, while he was cornered by ORIGIN staff, a young man about the age of 17 knocks all 5 of them out in an all-out brawl that lasted a solid 30 minutes. This man introduced himself as Akira Yamamoto, and took the boy to his family who were shopping in a supermarket a few feet away. The Yamamoto family took good care of Seto, giving him clean clothes, food, and water, as well as a place to live. They even enrolled him in school, which he excelled in after a bit. For once in his life so far, Seto was... actually somewhat happy!
However, the paths of the Diaboli's ruler and the now 11-year-old Seto would cross once again. Seto would return home one day to see the entire Yamamoto family cut into pieces in a bowl, Luciver consuming their cooked flesh. Seto would roar out in pain and anger, his entire body erupting into flames as he landed a solid hit on the demon before being given a chance to get away again by a hooded figure in white, who summoned a white-clad blade into his hands.
Mere hours later, Seto would get into another chance encounter with a young boy about his age. He had an odd feeling to him, like they've encountered before...This boy introduced himself as Yukio Ishida, the inheritor of the fortune of ISHI-DIRECT, the world’s largest technology-based corporation. The moment the two made contact, a tear in reality opened up, sucking the two in. When they emerged... they entered an entirely new world unknown to them. 
==== Connections ====
Seto and Yukio come upon a fantastical cyberspace world, meeting with the likes of six other children about their age - Kyo Hamasaki, a young child prodigy. Kenji Matsunaga, a social outcast with no specific desire to make any friends. Tatsuya Horiuchi, an enthusiastic boy with dreams of becoming an athlete. Mikio Okuda, a shy, but calm and collected boy with a love for flora. Mizuki Furuta, a young girl who aspired to join the fashion industry. And finally - Kenta Nishimura, a boy with self-esteem issues who aims to explore the world’s greatest landmarks. The eight explore this cyberspace world together - enduring hardships and growing closer as friends. They would eventually come across a group of hackers that threatened the livelihood of the world they were in. Seto, for the first time, stood up for himself and the realm he and the other kids had come to care for. It wasn’t just cyberspace to them. Each being in that digital world had a heart. Had a story. So - with his latent abilities, Seto sent each and every one of the hackers to some alternate universe.
However, doing this also separated the eight children from each other. Most of them returned home, but Seto and Yukio were taken elsewhere - to some mysterious town with even more mysterious happenings. As Seto got more accustomed to the world he was living in, his power began to spiral out of control as it did back in cyberspace. Beings ranging from maniacal space emperors to kings of darkness had arrived and threatened not just the town itself, but the whole galaxy. Through various battles - Seto had acquainted with the likes of Masanori Kataoka, a former space pirate and a government organization dedicated to multiversal travel to tackle his most personal battle yet: the one against Tatsuo Itoshi, who had used what was left of what he stole of Seto's blood to become a psuedo-immortal biological nightmare. Their clash was intense, and sparked the first awakening of Seto’s flames, a gift from Mizuko. 
==== Revival of the Celestial Blades ====
Seto was informed with hints of his origins while battling Tatsuo. The man constantly taunted him with little tidbits of info on how he was found until the point Seto couldn’t take it anymore, and destroyed him with flames hotter than that of the sun. Meanwhile, a mysterious void had appeared during the battles Seto fought. It terrorized the town he lived in, and would awaken Seto's greatest threat yet: The Supreme King Hikage, an ancient evil spawned from Seto’s negative emotion that had the power to cover the entire universe in pure darkness, merging any living beings into the void he created. 
Seto, with his new friends, would come to battle this ancient evil, but his negative emotions quickly overtook him, fueling the King further. Seto was overtaken by the Void. There, through a mysterious voice - Seto would learn of his origins as an Altairian. The voice would then guide Seto’s spirit to a mysterious set of ruins where the eleven Celestial Blades resided. The weapons were petrified, seemingly left to rot. However, Seto’s touch - the touch of a Vimnea royal, would open a hidden section of the ruins. Sitting there, was Respark - the blade that would bring salvation to all time and space and cut through cruel fate. Seto would pull the blade from its resting place - both becoming hope and unsheathing calamity.
The Eleven Celestial Blades were rejuvenated, and their chosen wielders were pulled from across the multiverse.
These were the likes of Yamato Akaishi, a hero-in-training with the desire to grant wishes of hope, Tatsuya Kurokawa, an ally of Yamato’s with a dream to eliminate a being known as the Dragon King, Ryo Morioka, a seemingly ordinary student with a love for tokusatsu, Yuito Akiyama, a scholar turned deadly android previously with the intent to obliterate Seto, Katsuro Nakajima, a reserved student with extraordinary learning capability, Ryouta Mitsui, a seemingly immature part-time bartender with an incredible, but suspicious knowledge of the multiverse, Shou Kubota, the prince of a wealthy nation gone rogue, and a mysterious man clad in black. The new Eleven Sovereigns battled the Supreme King, and Seto ended up awakening a form clad in indigo armor, known as the Knight of Genesis. The Supreme King was bested in the end, but the worst was yet to come. An ancient prophecy of Altairian legend - unbeknownst to the Sovereigns, was to come true in their next battle. 
The Luminary, a corrupt god of Altairian myth that would bring unforetold destruction to the universe, was unleashed upon the world - and used Seto as a vessel. This erupted into a deadly clash, almost resulting in the destruction of the universe with the use of Seto’s still-latent abilities. However, with a push from Yukio - Seto was able to free himself from the Luminary’s influence, and promptly defeated him in battle. However, as a result - it had become a permanent part of him, and the Luminary now rested within Seto’s soul, awaiting his next chance to strike at the world.
==== Beyond the Universe ====
Six months after the Luminary’s awakening, a being of unknown origin, calling themselves 'Monogatari' had appeared. Using the now dystopian universe that Seto originally appeared in as a base of operations, Monogatari threatened to erase all of existence using the fragments of a mysterious book-like object. This would eventually be revealed as the Sovranic Volume itself. If the Volume fragments were to be tampered with, universes would begin to crumble. Seto once again gathered the Sovereigns to combat this brand new enemy. The mysterious man clad in black wielding the Celestial Blade of Darkness would return as well, revealing himself to be an older Akira Yamamoto. Apparently, Akira’s soul had never left the physical world and wandered for years with ‘unfinished business’. Seto cried tears of joy at the sight of his former mentor, having a heartfelt reunion. However, it didn't last very long. 
Monogatari already began his plans, almost all of existence in what Ryouta called the ‘multiverse’ was erased. Seto once again took the initiative, gathering up allies from across the various worlds he had been to, ranging from the now aged up group he met from the cyber-space realm, all with their own magical abilities - to even heroes of stories Seto previously thought he could never meet. Monogatari’s armies and Seto’s armies clashed across the entirety of Seto’s Earth, while Seto and Yukio took on Monogatari together. In the end, it took Seto sacrificing his own physical form in order to save the multiverse that day - as he had attempted to contain the Volume fragments, which worked for long enough so that Respark could restore the multiverse that was lost. Seto was mourned by his close friends for weeks…
A year later, Yukio had created a device to gather remaining ‘AlterGenes’ from across the remnants of the battlefield in an attempt to revive Seto. It was a success, and Seto was brought back to life - but another battle was to be fought shortly after his return. The conqueror Overlord Zelgius had arrived to invade the universe Seto was in, and beyond. Returning to the battlefield once more, Seto and the Sovereigns would clash with Zelgius and his subordinates, ending in a victory for the Sovereigns, a return to form for Seto, and the freeing of countless universes under the Overlord’s control! 
Though a six-month timespan of utter peace had followed the Overlord's defeat, a large cult led by a boy named Masato Ishikawa had risen in the shadows and wreaked havoc. Following in Monogatari's footsteps, Masato threatened to cause an 'Ultimate Catastrophe', aiming to wipe out the multiverse as Monogatari intended to, but without the Volume. Ishikawa turned out to be a demonic hybrid, allowing him to access energy from the Diaboli and become what he called ‘Chaos Incarnate’. Masato and his cult would go after Seto and his allies constantly - eventually leading to a direct confrontation between Seto and Masato. Ishikawa would escape, marking the start of a long-standing rivalry.
==== The Singularity ====
After the battle, Seto and Yukio were picked up by a certain keyship, and their next adventure began as the universes merged into one. Masato Ishikawa had obtained access to the Void Singularity, and used its power to merge countless universes into one massive - and incredibly unstable - multiverse. In this new uncharted territory, Seto and the Sovereigns gained many allies, creating a group known as Brave Genesis to defend this unstable singularity from whatever threats were to plague it - alongside various other factions that were established in the chaos of it all. The group had moved to an altered version of the Sovereigns’ home universe, setting up a base in an estate Yukio had purchased quite a long time ago with some of ISHI-DIRECT’s funds. It took a few months - but Masato re-appeared. He attains the Void Singularity once more after it shattered into fragments following the multiverse’s formation. He planned on harnessing its power in an attempt to create a second Catastrophe, that could’ve endangered far more than what Monogatari would have affected. Seto yet again was able to stop it, but this time - Masato was actually brutally injured, despite escaping. Mere weeks after this, an entity created by the remnants of Hikage’s Void had captured Seto, leaving him in a pocket dimension for a brief while. Nothing of note happened - he was broken out of it by Yukio and Ryouta after a few days.
Following this - Masato’s cult was once again ordered to go after Seto and co. However this time - they had new tricks. Ishikawa had learned that the Diaboli’s energy could corrode and corrupt Sparklinen if enough of it was poured into a fragment at once. Masato’s subordinate Shingo Hayashida forced Seto into a berserker state with this corroded fragment of Stability, even giving him a new form for a brief time. With Yukio’s assistance, Masanori was able to put a stop to Seto’s rage by precisely destroying the corroded fragment of Sparklinen within Seto’s right arm. Despite its nature, this fragment would later allow Seto to attain levels of power unseen. In yet another encounter with Masato - Masanori had been mortally wounded, forcing Seto into his berserker state yet again. However, this time was different. No attempts at stopping him worked. The second half of his DNA would basically take full control over his mind and body, transforming Seto into a humanoid powered by what looked like energy from the void. He almost destroys hundreds of galaxies in an instant, even testing the hand of Destroyer gods nearby. Through Yukio’s memories, Seto was forced out of this mysterious transformation, awakening the form known as Draconic Lord, a power that cleansed the mass amounts of malice from Seto’s heart for the time being.
Another time of peace. Five full months of nothing but peace. However - in the shadows, Masato Ishikawa’s final plan was in motion. Utilizing the now completed Sparklinen of Corruption, he planned to recreate the worlds in his own image by traveling to Asteria and using the Map of the Stars, an Altairian relic with the ability to freely change reality to the user’s demands. Seto and the Sovereigns make their way to Asteria with the help of Ryouta - who according to Yukio, was looking more and more suspicious by the day. Within Asteria, Masato had already begun final preparations for the multiverse’s recreation, and Seto was even killed by Masato's ‘Grand Chaos Incarnate’ form, unlocked through further channeling of the Diaboli within his body. Then, seemingly like someone had flipped a switch - one of Respark’s hidden abilities was unlocked, and summoned one of the wielders - Asphodel to the battle. Seto is revived by the Altairian hero and alongside him, defeats Masato seemingly for good, saving Asteria. The Altairians recognize him as the crown prince of the realm, and Seto learns of his royal lineage as well as his true name of ‘Aegis’, once again taking the title of ‘prince’.
Not even a day later, Seto, as well as the rest of the Eleven Sovereigns fight a being also calling itself ‘Seto Izumi’. It looked like Seto. Sounded like Seto. Fought like Seto. It was him - from another timeline. The Sovereigns, as well as the group of heroes Seto assembled to defeat the threat were brutally killed, one by one. The last Sovereign remaining apart from Seto and Yukio is finished off by the alternate Seto, causing the main Seto and Yukio to go into an enraged frenzy, not in an attempt to defeat him - but in an attempt to KILL him. Something that no enemy has done before - driven Seto and Yukio to kill willingly. Yukio is knocked out after a massive struggle between him and the alternate Seto. Our Seto makes one final bet: the void abilities he harnessed in the battle with Masato.
In a twist of events, he ‘miraculously’ activates them. However, something… or rather, someone - takes the helm and controls Seto’s mind and body. The worlds begin to get consumed by darkness, as ‘Seto’ sends a chilling message to the denizens of every remaining world, threatening their destruction at his hands alone. Each and every world is consumed by the darkness, and swiftly ‘erased’. In an actual last minute miracle, Seto took back his body and mind - reversing the actions the entity controlling him had performed. This would reset the landscapes of the multiverse as a whole. The worlds that were crumpled together are unmerged, for good. Unfortunately, this move came with a heavy price. Seto exchanged his physical form in the mortal plane yet again for the peace of the New World. He enters Asteria, a realm where he still exists, but has no physical appearance. Seto accepts this fate - and continues to watch over his friends from Asteria.
==== The God of Malice and Ascended Destiny ====
As Seto watched over Asteria and the multiverse, the being known as the Keeper approached him, offering his abilities to Seto as one with a 'blank future' is unable to continue existing. Seto's story had already ended according to the Volume. However, he defied fate by gaining the ability to return to the mortal world… something unforeseen that the gods of the Astrum would look into. This was at the perfect time, as the eight months of relative peace the many worlds had was to be interrupted very soon. Upon Seto’s return - Ryouta had informed him of a large sphere of void energy, similar to Hikage’s - had been found inching closer to their universe.  a mysterious humanoid made entirely of Void energy appeared. Seto identified it as the Convolution, what he believed to be a newly formed hivemind he had found in his time observing the multiverse - that was assimilating other worlds into its mass, and at a rapid rate.
One of the many members of this mass brain would descend onto the world, and Seto clashes with it. Through the battle, Seto would observe many of their abilities, including their ability to  create black holes, in which one had allowed him to enter the center of the reforged multiverse. Through serious struggle, Seto defeats this one of many entities in the hivemind… however, it wouldn’t be the last he’d see or hear of them for sure.Within the area he had found himself in, devoid of human life, Seto notices a peculiarity. An observatory of some sort, freshly built. Seto would make a mental note of this - remembering to return here with Yukio and the Sovereigns once the time was right. Seto’s battle with the Convolution had caused something massive to happen however - the unsealing of Tiaos, the God of Malice that the Forger of Chaos sealed away eons ago. When the being appears in Seto’s universe - he was enraged, and begins with threatening the deaths of countless people trapped in Hikage, his creation’s void. When Seto and co. confront him, they learn of the Omnia - and of the Astrum of Void that fell to his lust for power: Shoarus. He gives the Sovereigns three days to prepare for a battle, in which the fate of two entire multiverses would be decided.
Prior to the battle with Tiaos however, Seto visits the multiverse’s center with Yukio. When they enter, they’re met with a familiar face - Asphodel. The two then learn that Asphodel had created the observatory, and has been keeping records of the history of the Altairian people. The two learn of the war between the Altairians and Volantian people that ended in a mysterious event that purged 75% of the Altairian population at once. Then - through a reading of a journal kept by one of Seto’s ancestors, Zeisis Vimnea - Yukio learns that he himself is a Volantian. Through putting the pieces together with the rest of Zeisis’ journal entries - Seto, Yukio, and Asphodel come to the conclusion that the Volantians and the Convolution were connected in some way - but how? That would be figured out soon enough. However, there was a bigger problem at hand - Tiaos.
When the God of Malice strikes, Seto and Yukio enter the Omnia alone and battle him together at their full power, despite the fact they knew it wasn’t enough. Through struggle after struggle with the god in trying to get at least a single good hit on him - Seto and Yukio fall. However, Respark’s summoning ability once again activates, but instead it summons the only living wielder of the blade - the Forger of Chaos himself. Vesyn had already been watching Seto and his allies for a while, but who was to think he would be summoned by the blade? It was nothing less of a miracle. The Forger would utilize his own unlimited Stability energy to ‘create’ new lives for Seto and Yukio, reviving them and once again allowing them to shatter the fate the Volume gave the duo. He also provides them with a little bit extra - a small portion of divine energy. This small spark would erupt into a massive inferno…
Seto and Yukio would reach their first godly transformations - ‘Ascended Destiny’ - and with the help of the Forger, would best Tiaos. Following the battle, in a heavy decision, Seto and Yukio would decide to split from the Sovereigns for a while. Following what they learned about Shoarus - the two aimed to train with Vesyn in order to harness their divine energy in the event he was to somehow revive. The group agrees, and the two newly-born gods would leave for the Vortex, where the Grand Sovereign resides. 
==== Roots ====
While the duo was way, Masanori and the other Sovereigns had to deal with four corrupt demigods known as the Demiurge, who aimed to shatter some sort of seal in the center of a realm beyond the multiverse, even going as far as to capture Yukio from Vortexia in secret in order to drag Seto towards them. Their plan succeeds, and Seto engages in battle with the four, defeating them while also cracking the seal they were trying to open up in the first place. The after-effects of this would soon show, in the worst possible way. Believing that nothing came from the seal being cracked ever-so slightly, Seto and the other Sovereigns went on an expedition to space! A nice trip to the red planet Mars, that quickly went awry. The group was bombarded by entities made of void energy, leaving all but Seto harmed. These mindless creatures then merged into one - revealing a humanoid form of none other than Shoarus. He would taunt the Flame Sovereign while they briefly battled, escaping before Seto could even land a solid hit on him.
Following the encounter with Shoarus, Seto and Yukio return to the observatory, to learn more from Asphodel and Vesyn about the Altairians and Volantians. The two go in-depth about the war’s catalysts and the previous wielders of Respark, the Vimneas. Through further investigation of Zeisis’ journal, and the logs of Asphodel’s master (and Seto’s grandfather) Xyros, they discover the Convolution’s origins, and how they came to be the hivemind: the Spark Removal Plan. The four also learn briefly of the Zenith War: a battle seen in shared Altairian and Volantian legend where the God of Void alongside countless entities is faced by hundreds of beings from across existence in a battle of light and darkness. 
This is when the Convolution had shown their full mass of what seemed like quadrillions of entities - declaring that they would head to Uni-X, where Asteria and Volantia stood, and open the gateway to the extradimensional space containing the core of Stability’s energy in that universe. After learning everything they needed to know, and re-awakening the second Blade of Genesis, Seto, Yukio, and their allies prepare for the final battle with the Convolution - despite how fast that it had come. Seto, Yukio, and their allies enter Uni-X via Yukio’s largest invention yet, a mecha with the ability to withstand staying in extra-dimensional conditions. Upon entry into Uni-X’s extra-dimensional space, the Sovereigns and their allies are met with the Convolution’s Core -  piloted by Shoarus, quadrillions of assimilated, and the First of Assimilation Seishin, the Zenith War begins. It takes even absorbing the now complete Omnipotent Volume, but the Sovereigns end up defeating the entire Convolution hivemind, leaving only Shoarus to battle. Now together once again - the Sovereigns head to the Vortex to train under the Grand Sovereign and Vesyn for a while. Approximately three months pass, and they return home.
Shoarus, after months of basically disappearing - re-appeared and declared war on the Sovereigns. In an encounter with Seto - he would reveal the plans he had made while a part of the Astrum. Alongside the newly transformed Altairian Goddess of Ruin, he had artificially created a child with samples of his own DNA that would eventually inherit his abilities, becoming an unmatched force of destruction that would spread across the omniverse and allow Shoarus to consume it all with the Omnia. Said goddess would then re-integrate into Altairian society. This goddess was in fact, Seto’s true mother - Cordelia Vimnea. Which could only mean…
Shoarus was Seto’s true father, and he absolutely hated that fact.
Seto would push his mind and body to their absolute limit in the rigorous training he would put himself through after learning this. His motivation was absolutely through the roof. Then - the fateful day came. The clash with Shoarus and his newly reborn Messengers of Void. Armies clashed. Akira Yamamoto’s soul faded away - being reincarnated by the Forger into a new Sovereign of Darkness, Akihiro Nagasawa. Entire multiverses would fall in mass from Shoarus’ display of sheer strength. A large majority of the Sovereigns, even with all of the spirit they could muster - were defeated. Seto, Yukio, Masanori, Vesyn, and Ryouta were all that stood left against the Astrum’s onslaught. The Forger had then called out of the blue for Seto and Yukio to pierce their fragments of the Volume with the Blades of Genesis. They reluctantly do so - and a brilliant pillar of light envelops the two. When it cleared, forms that transcended the Volume almost entirely had been born.
Seto dubbed these new powers ‘Unbound Destiny’. He and Yukio would once again clash with Shoarus, granted strength beyond anything they could have possibly imagined after attaining Ascended Destiny against that of Tiaos. In a single strike with Respark that merged all possible timelines’ versions of himself and Yukio into each other, Seto would land the finishing blow on his father, condemning him to repent for his sins wherever he may have ended up. Just like that, the Astrum of Void was finally defeated after eons of struggle, and after constant pain and suffering - peace had finally returned throughout the multiverse and beyond.
==== Advent of the Ultimate Devil ====
Before the next major battle had begun - a chain of events unfurled that led to Seto and co. encountering the Devil's Trinity. If you remember, Seto had a demon harbored within his soul known as Ankoku. His initial appearance all that time ago had begun this chain. When the Trinity - consisting of Astaroth, Beelzebub, and Caacrinolaas had manifested, they told of the unchaining of the Ultimate Devil: Bahamut Luciver. 
Then - they mentioned the realm of demons, the 'Diaboli'. This obviously brought up confusion, and of course - Ryouta was there to explain. When the Astrum were given life, so were three distinct realities. The Aeternitas, the realm of gods, the mortal plane or Mundi Vortice, and the Regnum Diaboli, the realm of the devils. The Diaboli is in itself - a multiverse. Seven universes, each their own hell representing one of the Seven Deadly Sins. Then - the eighth, where the ultimate devil is kept. Now with distinct followers, Luciver sought to escape.
And escape he did - at least partially...
The Ultimate Devil's manifestation brought upon great suffering, especially for Ankoku. Why? The being had killed the only person he could call family. Seto felt that same despair... but for what reason? That was when Seto and Ankoku's memories were finally restored from the help of a blade of anti-magic Ankoku kept within his body. As it turns out, Seto's adoptive mother had also taken Ankoku in mere weeks earlier - and the two had met once before.
Luciver's manifestation had filled Ankoku with vengeance, and Seto with suffering. The two - now finally reconciling as 'brothers', unleash the fourth of the anti-magic weapons stored within Ankoku's body - Zetten. Zetten allows for Seto and Ankoku to merge into one being, giving them just enough power to knock down Luciver and seal him in the Diaboli once more. 
But - this wasn't the end. Following the battles to come, the Ultimate Devil would bear his fangs on Seto Izumi once more.
==== Aeternitas and the Abyss War ====
Following the battle against Shoarus - Ryouta Mitsui formally introduced his true identity, easing the suspicions about him in an instant. He was the avatar of Ushignnex, one of the Astrum gods all along, and was tasked with watching Seto’s actions as he grew up and grew stronger. He deemed Seto and his allies worthy of meeting the Astrum, opening a gateway to Aeternitas, the dimensional plane of the gods. Seto, Yukio, and their allies enter Aeternitas, and meet the remaining Astrum. They are Phaias of the Sacred Elements, Helios of Light, Zyarin of Law, and the Grand Sovereign - who took Shoarus' spot on the council of five. 
Phaias and the Grand Sovereign praise Seto for his heroic actions, while Zyarin and Helios do not approve of his very existence - Helios especially, likely due to Shoarus’ betrayal which actively harmed Helios, as the two were once cherished friends. Before leaving the plane of the Astrum after speaking with them, Seto and Yukio meet Ordos - the creator of the entirety of the omniverse, for the first time, who commends them on their actions and allows them to access travel across the grand omniverse and even unlocks portions of their remaining 'potential'. The group thanks Ordos for his kindness, and they leave Aeternitas with a bit more knowledge on the world. This was only the beginning of two battles to decide the omniverse’s fate. The scale has grown exponentially.
The Abyss realm began to grow unstable, and large cracks began to open across the omniverse for an unknown reason. Ordos announces to the Astrum that the God of Apocalypse, Eschalon has re-awoken and the possible end of all existence was at hand. Ryouta alerts Seto and co., and the Abyssal War begins. The five strongest beings in the Abyss apart from Eschalon arrive on Earth one by one and wreak havoc on the world, preparing it for the arrival of the Apocalypse, as the god aimed to make the Earth his throne.Seto and the Sovereigns, alongside a few additional allies, take it upon themselves to battle them. Masanori defeats Solis of Annihilation, Yuito Akiyama (Sovereign of Metal), Yuno Hayashida (Sovereign of Smoke), and the hooded man from Masato’s previous appearance defeat Vota of Anguish, Shou (Sovereign of Water), Akihiro (the Sovereign of Darkness' reincarnation), and a mysterious man named Zarius defeat Vis of Demise, and Katsuro Nakajima (Sovereign of Electricity) defeats Ardore of Chaos.
Meanwhile, Seto and Yukio are taken under Phaias’ wing to learn of an ancient godly blade technique within Aeternitas known as the Kenkakusei. Going through months upon months in Aeternitas’ accelerated time learning the technique, the two master the ability before the final Abyssal Guard appears. This was Nihil of Calamity, the God of Apocalypse’s Grand Knight. Seto and Yukio both show off their respective Kenkakusei abilities in battle, Seto using ‘Hinokaku’ named after the First Flame 'Hinokami', and Yukio using ‘Kazekaku’, named after the First Wind 'Kazejin'. Nihil is defeated, and a massive abyss crack opens up in the air. The God of Apocalypse finally shows himself in a fit of anger and brings forth the tearing of every reality’s very foundation.
It was then revealed what exactly Eshcalon once was before becoming a god - a Levitian, a race dedicated to preserving the worlds' knowledge... and the Forger's oldest friend. Vesyn and Eschalon enter bloody combat while discussing their pasts, and it ends with Vesyn awakening his true Levitian power through his creation: Respark. With this new power - he almost crushes Eschalon completely. That’s when Eschalon takes his true form, becoming a being that can only be described as ‘eldritch’. 
Vesyn is promptly defeated, handing Respark back to Seto. The Forger unlocks something in the blade he had been hiding until the time was right. A way for Seto to communicate with the spirit realm - with the other Respark users. He encounters Asphodel, and the spirits of other users within his own inner mind. 
They all have a final talk about the situation and their future, ending with a somber goodbye between Seto and Asphodel. With tears in his eyes - Seto promises to carry on their will. With a promise made, the previous Respark users all enter a slumber within the blade, allowing Seto to access the ultimate Kenkakusei technique, the ‘Seikenkaku’, the awakening of one of the sacred Blades of Genesis. 
Unlocking a small portion of Respark’s true strength, Seto and Yukio blitzed through the infinite-spanning abyss, slayed Eschalon after immense struggle, and sealed the Abyss cracks, thus restoring balance to the omniverse for a little while. This war's twilight however... was the precursor to a much larger event.
==== Reverted Roots ====
In secret, Ordos begins to make his move - taking the Spear of End from the Abyss and allowing the weapon to absorb the remains of the realm, blaming it on the ‘Goddess of Ruin’, who apparently aimed to 'destroy the omniverse' with the Spear’s power. Ryouta alerts the Sovereigns of this, and orders them not to fight as it is a threat far stronger than they could imagine, which they all abide by for the time being - while keeping track of their friend's energy. The "Goddess of Ruin" arrives in Aeternitas not long after, defeating all of the warriors in the realm, including the Astrum, absorbing the five primordial gods.
Losing track of Ryouta’s energy, Seto decides to head to Aeternitas alone. He gets a first-hand look at the carnage and sheds a tear seeing the innocent slaughtered the way they were. Seto’s rage overtakes him, and he does battle with the Goddess. She utilizes various abilities from Seto’s past enemies and ends up defeating him after much struggle in the end, even shattering Respark entirely. The goddess takes an unconscious Seto to the final remaining bit of Abyss not absorbed by the Spear, allowing him to rest and recover. Yukio and Masanori arrive in the pocket dimension after a long while of struggle, and another truth is revealed. 
Why did she allow Seto to rest and recover?
This was the unfortunate woman turned into a Void goddess by Shoarus - Seto's actual mother, Cordelia. She put up the 'evil god' act to get to Seto and co. before Ordos did. She revealed that the old man had gone insane in his goals of keeping the Stability side - the side of the omniverse with creation's entities in it, thriving. All the while - he wanted to crush the Abyss entirely. Doing so would obliterate all of existence, and that worried her - and the Astrum. The five gods were alive and well for now, given the fact they were in on Cordelia's act.
However, in this battle - she also predicted a devastating loss. All of the Sovereigns would die. Including Seto. In the biggest decision they've ever made - they decide to fight Ordos together, willing to give their lives away. Once again gaining access to the spirit realm within Respark - Seto re-awakens the spirits within for a brief period to give birth to a new Blade of Genesis - Revolution. 
Then, finally... Alongside the Astrum - the final clash against Ordos begins. With each attack the Sovereigns launch, Ordos creates a perfect counter-measure for each and every one. 
Yuito and Yuno fall. Then Tatsuya (Inforce Sovereign) and Yamato (Light Sovereign) fall. Then Shou and Akihiro. And finally - four of the five Astrum. Ryouta is the final one remaining, and with the remainder of the power he and Katsuro had left... threw immense amounts of energy and their Celestial Blades into Seto alongside Yukio and Masanori. Mixing that with energy from the realm Ordos had brought them to - had once again brought forth a miracle.
Previously, Ryouta Mitsui had stated this, after going through the archives of the Astrum:
"Ordos was not the first being. He was not the genesis... An Altairian was."
"Is it Seto? Likely not. This being is responsible for the concept of power itself... a being donning light similar to Stability's as wings of unparalleled light. This Altairian was the creation of the Abyssal Tundra. The creation of Stability."
"They were the first one to reach the 'Zenith', the act where one can evolve infinitely. Past any limits, enemies, or obstacles."
Seto was the next being to tap into the Zenith.
He would inherit Ordos' title of the omniverse's guardian - and achieve the 'Omni-Unbound' form. Its infinitely-evolving power, alongside that of Revolution's now unbound capabilities allowed for Ordos to be defeated, the Spear of End to be destroyed, and balance to be restored in the omniverse. 
Ordos had fallen - and Ryouta now took the helm as Stability's guardian and the one to take Ordos' place for the time being.
Seto and Yukio guarded existence - while Ryouta served as an overseer.
==== Clash against the Ultimate Devil ====
Masato Ishikawa comes back once more - breaking the seal to the Underworld and re-unleashing him. Immediately - the Devil's Trinity are targeted, all but Astaroth being absorbed into Luciver's body. Unbeknownst to Seto, Yukio, the Sovereigns, nor the final Astrum Ryouta... the Ultimate Devil had planned revenge for the year and a half he had been trapped - starting with the destruction of Seto's home city, and everything in it. Millions silenced in an instant, being turned into lower rank demons through even LOOKING at Luciver's demonic magic.
When the Sovereigns learned of this - they engaged. Lower level demons were basically all around the world at this point, and higher-level ones were being unleashed as the 'tree' of the Underworld - the Qliphoth, which is actually a mana channel, was re-created. The magic channel branches out like the roots of a tree and descends to the seventh and lowest level of the underworld. At each level is a gate that normally prevents devils from moving between levels. Ten devils are set along the depth of the channel and are released as the gate to their level opens. Of these ten devils, the ones on the lower levels are stronger than the ones on the upper levels.
The ritual for opening this channel, known as the Qliphoth Advent Ritual has two parts. The first part is a magic circle that combines the World's Tree and the Dark Infusions of two beings. Darkness, which carries the power of the underworld, dyes the tree black and enables it to connect the living world and the underworld. The second part is a larger magic circle with three demons standing in positions along the perimeter and serving as activators for the ritual. If these three are defeated, the ritual will be halted. The ritual takes seven days to complete, at which point the World's Tree and Darkness users will die.
For this ritual, Caacrinolaas and Beelzebub - who use those magic types, were the catalysts. The mana channel and Luciver had ripped them of their immortality.
These were the 'final seven days' of the 'normal' world.
Seto and co. organize a raid on the fortress that was holding the two demons to both stop the ritual - and rescue them for Astaroth's sake. According to Ryouta, the resulting destruction of the channel being opened completely would devastate the entire continent and result in the massacre of 90% of the omniverse’s population, bringing humanity and every other race out there close to extinction.
Masato enlists the assistance of his three strongest officers in what remained of his cult - the Triumvirate, to open the channel, so they willingly allow themselves to be possessed by three Supreme Devils - Euronymous, Mastema, and Typhon. As the ritual begins, the Triumvirate take their positions as the activators. An invading group from Seto’s team splits into smaller groups that attack each of the Triumvirate with the intention of stopping the ritual.
Masato uses the information he extracted from Ryouta in their last encounter during the Ordos battle to develop a method for accelerating the growth of the tree. While the Triumvirate are fighting Seto's groups, the first gate opens and two devils— Proserpine and Lilith —emerge, appearing in Mastema’s chamber. The roots of the tree stretch up into the sky and begin absorbing the mana from the worlds, while a horde of lower-ranked devils breaks out of the fortress. With the gate to the underworld open, the Triumvirate members are able to access 100% of their devils' powers.
After Typhon’s vessel is defeated and knocked unconscious, part of the ritual's magic circle disappears, and the progression is slowed.
Now, after all the members of the Triumvirate are defeated by Seto and co., all of the magic circles disappear. However, the ritual continues because Masato has used his Modification ability to alter the tree so that it only needs one magic circle fueled by the magic and lives of the two Devil’s Trinity members. Shortly after, the next gate opens since Luciver has accelerated the opening with Masato’s eternal lifespan. As the horde of devils pour out from the second level, the half-manifested Luciver seizes control of all the lower-ranked devils and pulls them into a large mass, along with the lower-ranked devils from the first level and the coffins holding Beelzebub and Caacrinolaas. He then shapes the mass into a giant creature into which he can manifest himself.
Seto and Ankoku unite with Zetten and their Infinite Slash skill destroys the flesh monster and magic circle, stopping the Ritual entirely. However, Luciver condenses the monster's leftover flesh and manifests himself in his completed form. He then requests an ultimatum - Seto gives up Ankoku, and his world is spared. This was clearly a lie, and Seto denied the offer before activating Zetten again. Their clash took place within the mana channel Qliphoth - and it was BLOODY. Both parties were left barely standing following their clash…
Being in the mana channel for the prolonged period that they were - triggered something in Seto’s innate flames. It awakened the spirit of his and Ankoku’s earthen mother who had passed them down to Seto before her death. She explained that these flames… were special. Seto now had the ability to create, mold, and control the Flame of Autonomy, the ‘flame that lights up all existence’. Also known as the Gene-Ignis, it is a flame or energy that originates from a realm linked to Stability simply known as the Infernalis. It is believed to be the original flame and is regarded as being "pure and unsullied". Infernalis serves as a little-understood alternate dimension that is connected to the collective unconscious of humanity across totality, which links every possible user of the flame to each other. The Gene-Ignis is unimaginably powerful and can be used to bring both creation and destruction. 
Now with unlimited access to a flame able to bend even reality to its will - Seto and Ankoku's union separates, and the two take Luciver on as a tag team, nullifying his power with anti-magic and burning the Ultimate Devil with the Gene-Ignis. Then - with the last of their power... they sealed the Qliphoth and the Underworld once more, bringing peace yet again. At least for now.
==== The Creator’s Right Hand ====
About a year passes.
Peace and quiet had overtaken the worlds. It was nice!
All was well for Seto and co. as well... until Seto and Yukio suddenly had an outburst of sickness. No cure - no cause... it was unknown why they got like this.
However, of course the gods knew. Ryouta explains that the two were close to reaching the 'Absolute'. The Absolute is a threshold only surpassed by those that create their own ending unbound by the chains set by the Volume, surpassing even the Progenitor’s authority. No being apart from the almighty 'Progenitor' - the creator of all stories, even Ordos's, had surpassed it.
Learning of this - the Progenitor's right hand, a being introducing herself as Elysia, the first Altairian, hand appeared before Seto and Yukio with an offer. Sacrifice their abilities to continue living their lives at peace... or die as their bodies continue to evolve through the Zenith.
The two end up denying her offer almost instantly. There was very clearly an ulterior motive - that even Masanori snuffed out. She planned to turn against the Progenitor and take their throne. For what purpose? That - Elysia revealed herself. She viewed Seto as her perfect creation - made exclusively for her. A valiant hero who stopped at nothing to defend the ones he cared about. And in order to take Seto back and basically turn him into her doll - she held hostages. 
One of them was that of the Golden Dragon King Huanglong - who Seto had become friends with in his childhood. The other was the first person he met on his journey, before even Yukio - Yue Hiramoto, alongside the Silver Dragon King Tianlong. This was obviously too far. Seto ends up attempting to clash with Elysia, but to no avail. His body was far too weak to do anything at the moment. However - before she takes her leave, Elysia takes time to discuss more about Seto's origins. Something that even Asphodel or Cordelia didn't know.
Seto was linked to her as well - he was part of a clan of Altairians wiped out in the battle against the Convolution back in the ancient days - when the Altairian race was thriving: the Fatespawn. Alongside their race's access to the likes of Stability, the force of primordial creation... Seto also has the power to cut through fate in any way he sees fit. A Fatespawn's existence is intrinsically linked to the grand tapestry of fate itself The power to manipulate, reshape, and even sever the threads of destiny that bind all living beings is in his hands. Unprecedented control over the course of events in any possible world... he could forge new paths, alter prophecies, and defy any and all predictions. This... could be called the ultimate freedom in a sense, according to her. And according to Elysia - only one other Fatespawn remained. This was that of Seto's older brother, the second Altairian prince.
With all of this in mind - Masanori and the remaining Sovereigns traveled to Asteria in hopes of consulting Seto's mother for assistance. And as it turns out - he was closer than they thought. He was in their now restored home city, hiding out there until the time was right! When meeting with Masanori and the others, Seto's brother - Enmei, almost instantly accepted their offer to assist in the fight against Elysia when it came down to it.
The two brothers reunite, which marks the start of Elysia's counter-attack. Her very abilities would be sent at Seto and co. in the physical form of 'Constructs'. A total of four were sent Seto and co.'s way. The first - the Construct of Destruction, was defeated by Enmei and his dragon spirit - Tathamet. The second Construct - the Construct of Energy was defeated by Katsuro Nakajima after an attempt at reviving him succeeded - and was practically made null and void when he was killed. The Construct of Space was defeated by Masanori after unleashing his innate Levitian power. The final Construct, the Construct of Nothingness - was defeated by none other than Yukio. However, during that last clash - Seto was taken by Elysia into the Abyss itself.
She had begun to drain his abilities, memories, and even his emotions from his body in an... incredibly painful manner with the now rejuvenated Spear of End, which had become a blade known as Monoketsu. In a last-ditch effort, Seto takes a hold of Monoketsu, THROWING IT INTO THE INFINITE ABYSS. When it vanishes from sight - it hits something. The blade shatters the concept of the Threshold completely, bringing Seto and Yukio back to peak fighting condition. Seto's last ditch attempt gets a second wind - when with sheer strength alone, he shatters a hole open through the Abyss AND the normal omniverse, allowing Yukio and the remaining Sovereigns entry. 
(So Masanori, Ryouta, Yamato (who ended up becoming an angel), Shou (revived through normal means) and Yuno (who was brought back as a cyborg with Yuito.)
The final battle begins to save Seto. Infinite numbers of Constructs, based off of every ability to ever come into existence - surround the Sovereigns. The resulting battle was one of grand proportion. A full-on army against a group of five - and that group of five was winning. After both sides exhausted their resources, Elysia appeared with Seto as her puppet. All hope had been lost, seemingly...
Within the deepest depths of Seto's soul - a piece of him still remained. His ember of rebellion was still lit. With all of the force he could muster, his mind and body returned to him - and he shattered the crystals containing Huanglong, Tianlong, and Yue. He reunites with the Dragon Gods and one of his closest friends, after years of thinking he had lost them...
This infuriates Elysia, and she utilizes her full power, throwing Seto and co. out of the Abyss, sending them flying down towards Uni-X, and Asteria. During the fall - Seto and Yukio enter the spirit realm once more. But instead of meeting with heroes from the past, they're met with none other than the Convolution and Shoarus - alongside their lost Earthen relatives. Within their memories, Seto and Yukio discover their purpose for existing. 
Not to be a puppet of darkness. Not to become a part of a collective. 
But to be free. Free from authority. Free from death. Free from fate's chains themselves. They were the warriors of liberation of two races fallen from their grace. The sparks of rebellion against the corruption that has filled the story's heirarchy since the very start. With the blade harboring humanity's wishes he obtained during the battle with Luciver - Shinyaku, and the now shattered Absolute Threshold... Seto and Yukio reach their pinnacle. The ultimate peak of what they could do! 
Their True Divine Insignias - names that represent that they have reached the Progenitor's Ultimate Circuit outside of the Threshold, were unleashed upon all totalities that day.
Ignisia and Ventus.
Seto and Yukio attain access to the final blade forged at the apex of creation - Tenshukyo, alongside yet another result of their fate-defying abilities born from Seto's innate resonation with the concept of 'sword' and the concept of 'bond': Kizuna. These two weapons are used in tandem with the remaining Sovereigns abilities, and in a clash with countless lives on the line - start the final push to defeat Elysia. Within not even minutes, Seto strikes Elysia down once and for all, the Fatespawn comforting her in her final moments, promising to continue what he was created to do.
The battle is followed by a large-scale celebration, where Yue finally admits feelings she had been keeping from Seto since they met. By the end of the party - they had become lovers, and decided to spend the rest of their lives together.
It has been about two years since then, and Seto and Yue have already married and have had a child.
=== Genetic/Evolver Abilities ===
==== Fatespawn Introduction ====
As a Fatespawn who has practically transcended the concept of limitations, Seto is capable of shattering through any sort of power barrier he has come upon so far. With every battle, he continuously improves on his combat faults. On top of this, his proficiency in his Altairian abilities allows him to manipulate the forces of Stability, the realm where all stories begin. It is the embodiment of the very concept of creation, beyond any and all laws and concepts. By tapping into its power, Seto has been shown to re-create countless dimensions and universes after they were consumed by his father, the Astrum of Void Shoarus. With his Fatespawn physiology, Seto is also able to freely manipulate his own genetics to inherit entirely new traits and abilities, or even inherit genetic-based abilities from other beings, as well as have the ability to change the concept of fate to his will. This ability used to have a limitation, however that has long since been surpassed.
On the topic of Shoarus, Seto’s Void Leporian genetics come from him. With his Void abilities, Seto is able to manipulate the very forces of Abyss, where all stories end. This is the power that embodies the concept of destruction. It is the definitive end of all principles, beyond all laws and concepts just as Stability is. The two realms co-exist through Seto, which grants him ‘Equilibrium’, the equinox between creation and destruction. What this balance allows for is the gateway to the Zenith, the state of eternal evolution.
==== The Zenith and Absolute Threshold ====
In essence, the Zenith represents the pinnacle of one's development, where one has reached the ultimate level of growth, ascending limits,  achieving a state of infinite potential. Once one has reached the Zenith, they are no longer bound by many laws of the universe, the concepts of time, space, causality, etc. Seto possesses a level of power and understanding beyond the comprehension of most beings in his own reality. Seto is able to evolve past any obstacle, enemy, dimension, etc. without even thinking of doing so.
Seto also possesses the Sovranic Volume, a primordial concept created by his story’s progenitor that manifests itself with Seto and his allies as a book-like object. It represents the greater story that the Progenitor has written. It is ever-expanding, encompassing infinite timelines, universes, etc. within its pages. Utilizing the First Blade of Genesis Revolution, Seto can edit portions of the Volume to fit his ideals. Although, approval from the Progenitor themselves is required to make the change if he uses Revolution to do this.
And now, for the Absolute, a threshold only surpassed by those that create their own ending unbound by the chains set by the Volume, surpassing even the Progenitor’s authority. This, to Seto, is the ultimate ‘freedom’. Not being bound by even the creator of his own story. He represents the ultimate expression of creativity and free will, able to shape the 'story' in ways that even the Progenitor could not have imagined. Nothing on any scale, is able to exceed or overpower the Absolute; it is simply the fundamental transcendence of all that is and will be, whether it is cataloged or not, whether it has a description or not, whether you can think of it or not. In layman’s terms, the Absolute surpasses every single aspect that creates a ‘limitation’ set forth by the creator.
=== Notable Abilities and Techniques ===
==== Gene-Ignis ====
Granted to him as a last gift from his Earthen mother, Seto has the ability to create, mold, and control the Flame of Autonomy, the ‘flame that lights up all existence’. Also known as the Gene-Ignis, is a flame or energy that originates from a realm linked to Stability simply known as the Infernalis. It is believed to be the original flame and is regarded as being "pure and unsullied". Infernalis serves as a little-understood alternate dimension that is connected to the collective unconscious of humanity across totality, which links every possible user of the flame to each other. The Gene-Ignis is unimaginably powerful and can be used to bring both creation and destruction. Undeniably, the flames were the cause of the destruction of the Demiurge’s alternate totality, but have also been shown to give life to barren wastelands. Being from an alternate realm, the Ignis does not conform to the physical laws of any world; they grant a tremendous boost of strength to someone who is linked to it, and in some cases can even enhance their abilities to grant amazing powers that would normally be impossible even for pyrokinesis, such as cooling the heat that causes the natural expansion of the universe to slow down the flow of time, or heating up surrounding atoms to increase their mass to nullify gravity. Some of the flames emanated from the Gene-Ignis are able to exceed even the Planck Level and break the laws of hyper-thermodynamics. They also allow the burning or alteration of even non-flammable, incorporeal, or abstract concepts like time and non-existence. The realm of the flame’s origin is also said to keep the spirits of the fallen users within it if they so choose.
==== Will of Generations ====
Seto possesses an unwavering willpower that allows him to passionately accomplish virtually anything. Seto is entirely resistant to all forms of control and enjoys complete autonomy as his willpower is sufficiently powerful enough to overcome every barrier. His will goes beyond this, enabling Seto to completely and perfectly transcend any and all boundaries simply by wishing himself to, going so far as to gain a total and complete oversight over himself, making his very existence answer to himself alone. Beings like Seto who possess immense willpower are capable of pushing themselves to, and then beyond, any possible limits through the sheer strength of his will.
The majority of superhuman levels of willpower allow for an individual to persevere in their efforts against overwhelming obstacles since their strong intention may overcome elements which are personal to themselves, including suffering, dread, injury, and even death. Certain individuals also have the ability to push extraordinary levels of willpower on other beings, supplanting their own will with their own. Seto's Will of Generations takes this a step further by possessing all-inclusive willpower that overcomes everything that stands in its path. Reality, logic, causality, the end, and a variety of other concepts, laws, etc. are all rendered irrelevant in the face of Izumi's unwavering determination. As a result, it has a limitless scope and can theoretically be utilized to achieve all things. This sheer will is incorporated into various other feats Seto can perform. Basically, it is literally just ‘the indomitable human spirit’.
==== Vessel of Abyss ====
Abyss the realm of absolute nothingness, the absence of all existence and non-existence, and the complete absence of all attributes, properties, and qualities. The Abyss is considered the ultimate end of everything by default, as it is the state where all modes, all attributes, and all systems cease to exist. It is beyond all conceptual frameworks, as it transcends all forms of reality, inactuality, etc. In essence, it is the end of all things, the point at which everything simply ceases to be. It is a state of pure emptiness, where terms like existence and non-existence are rendered absolutely meaningless. The Abyss is often seen as both terrifying and liberating because of this, as it represents both the ultimate annihilation and the ultimate freedom from all limitations set by these frameworks. Seto tends not to use Abyss as much as Stability however, for reasons relating to past experiences with Shoarus. Its main purpose is to destroy all. Cause utter devastation to all that encounter its energy, being a polar opposite to Seto's other energy.
==== Vessel of Stability ====
Stability is considered the ultimate beginning of everything by default, as it is the state where all modes, all attributes, and all systems come into being. It is beyond all conceptual frameworks, as it encompasses all forms of reality, actuality, potentiality, etc. In essence, Stability is the beginning of all things, the point at which everything comes into existence. It is a state of pure abundance, where existence flourishes in its most primal form. A realm where all things are present and accounted for, both the tangible and intangible, the visible and invisible, the known and unknown. All attributes, properties, and qualities are present in their fullness and perfection, without any lack or deficiency. Both this realm and Abyss can be controlled and manipulated by Seto, to his very will in even his base form. He can use Stability in specific to perform anything that remotely relates to creation. For example, he can create abilities and bestow them to others, forge infinite amounts of weapons of both mortal and divine construct, and an infinite amount of other ‘miracles’.
(Both Abyss and Stability cannot be used at their fullest potentials, despite Seto’s access to them. Doing so would cause the obliteration of both Seto and all of his reality, including EVERYTHING WITHIN IT.)
==== Pre-Genesis and the Unalloyed Forge ====
Pre-Genesis is a dimension of nothingness outside of any and all realities. A world devoid of both Abyss and Stability, created by the first Altairian, a being who was said to have unfathomable abilities that allowed for him to mold the race and its home into the prospering utopia that it was. Formed by a spatial severance through the use of Homura's eternally burning flames, compressed and intertwined by stratifications of intense wind from Makitsu, the Celestial Blade of Winds, a virtual dislocation of a dimension's own flow of time and space allow this dimension to open. Within the Pre-Genesis, Seto’s will creates a reality inside of the dimension, known as the ‘Unalloyed Forge’. It’s described as a clear-skied plain, devoid of destruction with a bright green field spanning across all directions. Artifacts from across all of time, space, and reality were all forged here, both divine and mortal, and can be seen planted into the grass around the middle of the field. He can utilize all of these objects masterfully in this dimension. The knowledge carries over to the normal realities if he trains enough, too. Alongside this, the Forge serves as Seto’s observatory into the infinite worlds.
There is a bit more that Seto can do, but these are the more important abilities and powers.
=== Weapons ===
There are a LOT of these.
==== Homura, Celestial Blade of Flames ====
One of the Eleven Celestial Blades of Genesis, physical manifestations of only a small portion of materials that make up Stability, the energy of creation.  It also serves as Seto’s main weapon. This blade is granted to the chosen wielder of the original Blade of Genesis. It is embedded with a shard of the Sacred Core of Flames, Hinokami, which allows it to create, absorb, and utilize flames of any kind. The flames of this blade can burn from the temperature of a standard oven up to the heat of the Big Bang, guaranteed to burn through everything in its way, even space itself. The Sacred Core Guardian of Flame, the original user of the blade during the war against Tiaos, God of Malice, guided Seto into finding the spot where the blades once rested, and allowed for him to inherit it and unknowingly unsheathe calamity.
==== Revolution, First Blade of Genesis ====
Revolution is Seto’s favored weapon, granted to him during the battle against the ‘Supreme King of Void’. Made entirely of Sparklinen, the purest physical form of Stablity’s energy, the blade has shown feats that surpassed even the gods that created it in Seto’s hands. The blade utilizes the Sacred Cores utilized by all twelve Celestial Blades, granting it various elemental abilities, such as fire, wind, electricity, and darkness manipulation on top of its reality-reshaping abilities through its weakened version of the Progenitor’s ‘Overwrite’. Overwrite is the direct reshaping and rewriting of the elements of the 'story' through that of the Sovranic Volume, with limitless possibility to what Izumi could rewrite. However, there is a single catch. The Progenitor must authorize Seto’s action before the Volume is rewritten, unless it is an absolute emergency, and only two Overwrites can be used without severe consequences for Seto’s body and mind.
==== Juuchi Yosamu and Yawarakai-Te ====
A pair of swords that Vimnea (an alternate Seto) uses as his primary melee weapons. Their lighter weight and Vimnea’s skill with them make them extremely reliable to use. The Juuchi Yosamu is a blade corrupted by an unknown dark flame. Without discrimination, it cuts and burns through anything in its path. The Yawarakai-Te on the other hand is the ‘finer blade’ of the two, as it does not needlessly cut that which is innocent and undeserving. Basically, it will only harm the ones that Vimnea aims to harm, and not cause unnecessary damages to life and property of the innocent, similar to that of Zetten’s ability.
==== Four Demonic Blades of Sealing ====
These four blades gradually appeared before Seto before he reunited with his ‘blood brother’, Ankoku. All four blades are able to utilize Anti-Magic, which can nullify and destabilize most if not all forms of magic and even destroy a mage's capability to utilize magic, and each blade is reliant on different factors to remain active. Here are in-depth descriptions of all four.
===== Matsuba, Demonic Rage =====
The weapon resembles a large greatsword that is heavily soiled and scratched. A fuller connects the hilt with the blade despite keeping them separated. As with a typical longsword, the hilt appears as a handle. The base is angled inward and points inward while the blade is enormous and has a pointed tip. The sword's flat can reflect magic while its edges can cut through it. However, if it were to be used to cut anything else, it would be reduced to a blunt sword that wounds opponents with physical trauma. However, the sword's tip is still sufficiently pointed enough to cut someone. By striking the person's skull with the crossguard of the sword, mental enchantment can be broken. The width and length of the sword can be increased by extending anti-magic from the blade's edges and expanding it into a bigger blade. Longer ranged attacks and larger defenses are made possible by this increased size. The user can make the sword hover and fly through the air by manipulating the anti-magic within it. The user could also mount the sword and ride it, or they could utilize remote control to launch a long-range strike. The blade relies on the emotion of rage to function at its best.
===== Machiken, Demonic Blaze =====
The sword is mostly covered in mud and has black marks on the blade. The sword also includes a highly elaborate grip with a spiral pattern, a sphere for the pommel, and a hilt with a four-sided guard. The sword can absorb magical force from other people and cut magic with its sharp edges, burning with anti-magic hellflame. However, when used to cut anything else, it is reduced to a blunt sword that harms the adversary through physical trauma. The sword's initial power is its capacity to hold onto magical energy before releasing it in a flying slice. The black markings on the blade begin to glow with a hue that corresponds to the absorbed magic characteristic when it has absorbed a certain level of magical power.
When the user swings the sword at that point, it launches a flying slash with abilities similar to the absorbed magic attribute. As an alternative, it has the capacity to be filled with anti-magic, which would cause it to shoot out flying slashes made entirely of anti-magic. The sword's capacity to link its user with comrades is an additional benefit. With this skill, the wielder may send magic and knowledge over vast distances to their allies or collect magic power from them.[ It has been noted that the sword is incredibly heavy and passively absorbs magic from anyone holding it. By impaling an opponent and allowing the sword to drain their magic power and weaken their enhancements, one can employ this absorption skill offensively. When the sword is wielded in Seto and Ankoku’s Danketsu form, spikes and a knuckle bow extend from the sword's guard, and the slash projectiles are much larger in size.
===== Mareiken, Demonic Shattering =====
Unlike the previous two blades, this sword has a distinctive blade end with a broad edge that resembles the top of a lotus flower. When a holy magic user takes it up, the majority of the dirt comes off to show a sparkling blade. Initially, it is mostly covered in dirt and grime. It transforms back into its soiled state after its incorporation into Seto's body. The sword's edges can cut through magic and spells, but it also possesses the unique property of ‘Thread Shatter’. By breaking the chain of cause and effect, it absorbs and expunges the effects of most magic abilities through anti-magic tendrils that radiate from the sword. These tendrils touch those who are under the influence of magic before drawing back into the sword, rendering the blade black.
The other anti-magic weapons are unable to achieve this and only impact active magic. However these tendrils eliminate both magic and its effects, such as tissue damage brought on by a magical poison. This is because the ability alters causality. Even powerful spells such as magic of reincarnation don't have a chance against this power. The cross-guard of the sword creates a circle, amplifying its magic-neutralizing power when used by Seto and Ankoku in their Danketsu form. This blade’s properties were able to nullify the memory magic utilized on both Seto and Ankoku to erase the memories they had of each other when they initially met. This blade now serves as Ankoku’s main weapon.
===== Zetten, Demonic Blade of Reunion =====
Forged from Seto’s creation abilities and Ankoku’s latent demonic magic, this blade serves as the symbol of their brotherhood. As with the other anti-magic blades, this katana is capable of cutting through magic and spells with its edge. It is also capable of releasing flying slashes of anti-magic. When at its fullest output of anti-magic, the blade generates an aura of anti-magical energy that weakens the magic of opponents, making it more difficult for them to cast spells or effectively counter the sword's attacks.
However, its true potential lies in its ability to allow Seto and Ankoku to merge into one being. In this state, the sword resonates with the emotions of both Seto and his ‘blood brother’. This is known as Danketsu, a state where Seto draws on the full power of Ankoku, and assimilates him into his body, enabling the two to contain and control the power of anti-magic dramatically, increasing their own power and capabilities. Seto takes on physical traits that Ankoku has, such as horns, a tail, and slit pupils, as well as being garbed in anti-magic power. When used in Danketsu, any and all of Zetten’s attacks damage only the intended target and do not cause any harm to what the user wants to protect.
==== Monoketsu, Vessel of the Primordial Realms ====
Originally the Spear of Ordos. Through a cataclysmic event, the spear absorbed immense amounts of energy from the Abyss, infusing it with the raw power of chaos and creation. The transformed weapon took the form of a magnificent blade, radiating an otherworldly aura of dark energy and iridescent light.  By wielding Monoketsu, Seto gains the ability to manipulate and control both the Abyss and Stability, seamlessly navigating and manipulating these opposing forces, balancing them to achieve a transcendent power beyond what he’s seen in the past. It also possesses the extraordinary ability to pierce through the concept of the Absolute Threshold. The Absolute Threshold represents the highest point of existence and power, beyond which beings originating from a mortal race cannot ascend past. By wielding the blade, Seto can cut through this conceptual barrier and all barriers, surpassing limitations and venturing into realms previously thought unattainable. Currently inaccessible, as it is floating through what remains of the Absolute Threshold.
 WARNING - Use of the weapons below, even in the smallest amounts for ANY reason, ‘rewriting’ or otherwise, is incredibly dangerous for Seto, and risks his very destruction on a conceptual level. (However, holding the weapons is a different story.)
==== Shinyaku, Power to Rewrite the Story ====
Gifted to him by a being beyond totality known as the Leviathan, which is directly under the Progenitor hierarchy-wise, Shinyaku is a blade that allows Seto to use his power to the fullest. Seto gains unrivaled control over the metaphysical foundation of reality thanks to Shinyaku. He has the ability to rewrite, alter, and shape the 'story' itself with the simple swing of the blade. This includes changing people's destiny, changing the rules that govern the multiverse and beyond, and changing the fundamental concepts that facilitate existence. He gains control over a number of forces, elements, and aspects of existence. Shinyaku gives Seto the freedom to use these powers however he wants, whether that be to command the elements, change the course of time, or alter the laws of physics. With Shinyaku, Seto's control over the 'story' becomes almost absolute. He gains the ability to disregard the predetermined guidelines and restrictions, to freely bend and reconstruct the metaphysical law to his will alone.
==== Tenshukyō, Limit-Shattering Finality ====
Known by some as “Eternity," this weapon is said to have been forged by the unbound potential and indomitable will of one who has shattered through the confines of fate itself. It is not a creation of physical craftsmanship, but rather an embodiment of pure metaphysical energy. It is an ethereal blade that resonates with the essence of cosmic freedom and unrestrained power. This extraordinary weapon defies the constraints of conventional weaponry. Its form is fluid and ever-changing, shifting between states of solid and ethereal, defying comprehension and challenging the laws of existence itself.
It is believed to be the sword that gave birth to all realms, even that of Abyss and Stability, under the will of the Progenitor. A blade that truly has transcended the concept of limitations, it is no longer a mere weapon. It is now a conduit of Seto Izumi’s indomitable spirit, liberated from the world’s constraints.  With each swing of the blade, every possible realm is shaken, unraveling all that is, and all that will be, shaping the path to the faraway future. When Tenshukyō is swung, similar to Shinyaku but in a far larger sense, it has the ability to rewrite fundamental concepts of totality and even nullify abilities that manipulate these concepts themselves, such as the manipulation of time, space, concepts, laws, reality, etc. A boundless wave of energy created by Equilibrium energy (a fusion of Abyss’ destruction and Stability’s creation) is sent out with each individual slash which nullifies these abilities at even their smallest possible level, reverting what was done with the power back to the way it was immediately before the ability was activated, completely nullifying them and preventing them from becoming "real”. This blade completely denies even absolute manipulation of these powers, being an ‘absolute undo button’ or ‘absolute Ctrl+Z’, if you want to put it that way.
==== Kizuna, Bonds Beyond Finality ====
A sword forged by Seto, and the bonds he shares with his allies. The perfect sword that has transcended all possible limits and reached realms beyond that of even Tenshukyō, created by merging it, the katana forged by Mizuko Izumi, and fragments of countless other swords into one single entity. Becoming the progenitor of Abyss and Stability, this new blade now grants Seto access to the Onmyodo, the realm beyond that of the opposing, but interconnected realms. The world that only the Progenitor once reached in his prime. Using Abyss as the receptive, and Stability as the active principle, the concept of finality is completely unraveled, thus creating the path to oneness, Seto becoming united with totality itself while remaining in a mortal-borne body.
As Seto's ideal sword, it can cut through anything just as Tenshukyō can, but to a far higher level. With absolute power over all realms of existence, this blade surpasses even its own origin. Liberated from all concepts and laws, things such as bonds, causality, fate/destiny, and the very ideas of Karma, Infinity, and Zero. Nothing is safe from this blade’s edge. Onymodo’s essence surrounds this blade’s sheathe at all possible times, granting Seto a form of ‘absolute defense’. It dissipates into unabsorbable particles and becomes a "portable fortress" that blocks off any and all interference, even up to uncountable, inaccessible infinite dimensions. Instead of being primarily for rewriting the world, Kizuna is able to cut through it with absolute ease. Heavens. Dimensions. The hierarchy itself. All can be cut through Kizuna, no matter what it may be. Tangible or not. Cataloged or not. Visible or not. It is a manifestation of defiance, a symbol of liberation from the predetermined paths. Due to reaching power beyond even the Progenitor, any mortal/non-god who uses it is bound to die as well, although the blow is almost certainly going to take the life of its opponent no matter what.
