Nex/Biography

==23XXAD Early Life==
Knowing little about himself, Nex's history is one that is shrouded in mystery and discrepancies that contradict his beliefs. These times of his life are shared through memories and nightmares, and thus can be considered slightly unreliable.
His young life revolved around living with a girl named Yura who enjoyed a tranquil existence with him in some kind of sealed space, this place untouched by horrors and the plague of the world known as the Seithr Scourge. Yura had taught him to value the world and life, and even instilled the importance of the Azure to him, and a young Nex enjoyed her company. Evidently, this always becomes a nightmarish scene, where this space decays, Yura gives Nex her Azure Locket, pleading to him to escape before she dies by corruption beyond a mortified Nex's control. When this corruption happens, the Boundary Management System intervenes and takes her soul away leaving her to become a husk.
In nightmares, he is often thrown into twisted realities where horrors of Seithr torment him after Yura's disappearance, though this is likely a result of the Azure Grimoire's will tampering with him.
Evidently, this is one of the primary causes for his disdain of the system and the puppets it uses. He also retains the locket that Yura had as cherished memories of his old life, and this locket is a means of reminding himself of his reason for fighting.
Supposedly there were people observing these events, but Nex can't recall them. He also seemed to hear the 'Voice' of the Azure Grimoire or the entity of its power ever since he was young and held some connection to the Azure even before receiving the Grimoire.
==2390AD - Grimoire of Destruction==
===Fated Awakening===
Nex awakened in the ruins underneath a city once known as Izanagi, completely unware of its history and one fraught with decay known as the Seithr Scourge. It had been abandoned, and the target of some kind of disaster. He awoke without an understanding of his situation, feeling lost but feeling an odd familiarity to the ruin of the area.
He would meet a man named Corvus who was informed on the city's situation, though Nex was hardly concerned, and instead wished to know Yura's location, only to be told she didn't make it. This causes the young teenager to lament on his lack of strength and wishing to find the Azure to change his situation. However, Nex became separated from Corvus once a being wearing armor appeared, Nex recognizing them from somewhere. Corvus would go on to explain that they are Azure Interface Prime Field Devices, and their appearance would mean the system is attempting to stop Nex's possibility from altering into a threat. As the strange beings continue to gauge Nex's threat level, they would chase after him through the ruined city. Displaying former knowledge of some kind of combat technique, Nex manages to damage one's armor with a punch, but sheer numbers overpower him.
When a woman named Irene intervenes, the AIP all stop, and she takes the injured Nex back with her to the Novus Orbis Sequentia.
===The Boundary Management System===
Nex spent a time in the custody of the World Order, as the monitored him to determine what he would become. It was here that he would meet Serza for the first time.
===Life in the Shukuto Refuge===
After managing an get away from the System's constant watch with Serza's help, Nex would find himself just outside of the place he awakened. A small refuge built for the survivors of the horrid incident that befell Izanagi and reduced it to that state. Although he didn't know what this incident entailed, Nex was far too exhausted to protest his new home. A young woman who knew the one helping Nex, Corvus, would agree to keep him safe here until he could leave the refuge on his own one day. 
Nex didn't seem to get along with many people, but a girl named Nozomi changed this.
===Contact with the Azure Grimoire===
Nex's search for the Azure tugged him to a certain place in the ruins of Izanagi just outside of Shukoto. There was already someone here, though Nex couldn't discern their identity. With their power, a Prime Field was overtaken, and its programming corrupted, unbeknownst to Nex. Nex could not fight the Prime Field, and it severely wounded him. Unable to protect himself or flee, the terrified Nex was swallowed by the Gate expanding out of control and absorbing everything around, including residue energy from the ruined city of Izanagi. Although his Azure awakening protected him to a degree, Nex would still float through the depths for what felt like an eternity. Immense suffering and lingering pain greeted him as he sensed an Abyss that even the Azure could not handle being within. He met some kind of force within it, but when his locket that Yura entrusted to him glowed a brilliant blue he managed to find pick up the pieces of his breaking mind and leave the Gate before he was lost to it.
When the dust settled, the individual was no longer around, and the teenager emerged with a Grimoire clustering his body in a coating of solidfying Seithr, more being attracted to it. His body was no longer his own, sharing it with some entity that revealed itself to be the voice that was reaching him the whole time and could speak to him freely if he was near the Boundary. For Nex, this Grimoire appeared to be the only way for him to reach the Azure. 
===Destruction of Shukuto===
The young Nex could not control his Grimoire, and the trauma of being thrown into the Gate consumed him briefly. He would go on a rampage and destroy Shukuto, tearing everything he cared for down subconsciously as the artifact fed on the souls and fear of the refuge. Coming to realization of his own atrocities, Nex furiously proclaimed this wasn't what he desired the Azure's power for. With the events attracting the attention of the Governments, they began to arrive at Shukuto in a hurry to find where the Azure was, however, while everyone was looking in the ruins of the old city where the contact had been recorded, Akuhei would locate Nex and met him for the first time. After mocking his situation and confirming that he had the newly-formed Grimoire, Nex believed that Akuhei had something to do with the entire situation, and directly lashed out at him with the power he obtained. Despite this, he was soundly beaten and toyed with by the General, who seized him afterward to bring him to a lab in the outskirts of Iwasu and Naobi. 
It was previously left uncertain what occurred to Nozomi and the ones Nex knew at the refuge, but as Children of Sin has revealed, she survived the accident caused by the Grimoire. 
===Captivity===
For months, Nex was kept inside of a containment center, although these events are not ones he has shared, he claims to have been treated rather poorly. It's known that the Marshal of the NOS, Lukain, was primarily responsible for the one overseeing what was done with him in this time. 
===Origin-Tie-In: Entrusted===
Two beastkin were sent on a mission to save Nex, receiving it from the sole surviving Observer, Legna. 
==2391AD - Children of Sin==
===The Cities of Eternal Machinations===
A short time after being on the run with Imyo, Nex is forced to abandon another hideout with his guardian when the SIA are in pursuit, being informed by Lukain of Imyo breaking Nex out. The pair are chased all the way to a destroyed research sector outside of Naobi. Imyo would decide that he couldn't handle this on his own, and decides to call in for backup who would not draw too much attention from the NOS. During this, Nex attempts to escape on his own, eager to get back at the NOS to find out what the system did with Yura, believing he now had the strength to stand up to them. Imyo brings him to reality, retorting that he's not ready to face the World Order, let alone Akuhei or Lukain. 
As it becomes apparent of who Imyo's backup was, Nex would be unwittingly made a member of Imyo's strange band of mercenaries, consisting of Locke, Spence, Switch and a golden-eyed girl named Cerea Anderson. Initially, he is disinterested in the squad and only follows along as he has no other present option. Although they spend time together at a campsite, Nex still shows no interest in socializing and sleeps by himself, feeling out of place among these new people. Although he sleeps, it's only to have nightmares where he is pestered by the Grimoire reminding him of his situation. It then flares up in the middle of the night, encrusting on his arm, and he rushes out to calm it down by utilizing a growth of a cluster of crystallizations of Seithr and natural mana. Nex is joined by Cerea, who is curious about his situation and makes an attempt to understand it. Nex would mention that the crystallized constructs have always helped him, and it was one way to calm himself down. Although the pain of the Grimoire makes Nex leave, and he heads for the abandoned research sector past Locke's watch. There, he releases the build up of Seithr Scourge from his body and is relieved of his pain by doing so, though much to his surprise, Cerea followed him. It earns a quick scolding from Nex who warns her not to touch the substance, but once again to his alarm, it doesn't harm her. Nex's actions only attract attention and the NOS pin their location down while Nex and Cerea flee back to the campsite. 
Once Nex and Cerea arrive back to camp safely, he is dismayed to see that Prime Fields controlled by the Boundary Management System break through a barrier that Switch made to hide their location. The NOS seals them in their own campsite and tries to grab Nex, a mistake that costs a soldier their arm which becomes scourge. The campsite is bombarded with this ambush, and Nex is unable to handle the strife caused, and slowly, he starts to let his Azure take hold. Matters seem to turn for the worse with Rythrean appearing and Lukain himself next, Nex's Azure falling out of control and the Grimoire trying to break free would have caused him to consume the lives of everyone in the vicinity. Lukain is certain this will be the outcome, however, Cerea brings the earlier cluster of crystals to a struggling Nex and it fills him with warmth and natural energy. Though a different reaction occurs from within Nex that he can't discern the origins of, but believing it is still the Azure's power, he uses it. He is then able to launch an attack at the Marshal, disrupting his focus and causing the devestating Boundary manipulation technique to instead hit the upper structures, causing it to come crashing down. This bedlam is enough to allow them an escape when Switch trasports them away with a teleportation command. 
With the only destination available being the lowest level of Naobi, Nex would once again meet the unfriendly up and coming Commander of Sector 0, Nicaiah. Nicaiah clearly had nothing but ill to say of Nex due to his Grimoire, reminding him that she was why Imyo was able to save him. Nex would also listen to Cerea's sorrow of her missing her family, which she lost in a unknown conflict with the NOS a few weeks ago. Unsure of how to respond to this though, he'd remain silent. After Nicaiah agrees to help Imyo, she sends several crates of supplies to them, one of which is for Nex. A Seithr Regulator fastens on his hand to hopefully keep the odds of another disaster down. 
Imyo would bring Nex and the others to the higher levels, they passed through the entrance to the military area. Nex was questioned by guards, before being recommended to join the annual Souls of Supremacy tournament that Naobi would be hosting in a day. This was all much to his chagrin. However, Nex would be further surprised by the arrival of two individuals, Arcius and a familiar face in Serza. Unaware that Serza was now part of the Sequence Destroyers, Nex is left in confusion, telling Imyo and the others that he knows Serza from his time in the Shukuto refuge. 
As they arrive to the residential district of Kanpeki, Nex expresses his disdain for the crowded district. Eager to leave, he waits to see if his guardian can secure a card to get them out of the City via a warp node. Just as this happens, Nex is spooked by the sound of Akuhei's voice as the General informs the citizens of Naobi of recent events, filling in for Lukain. Although it is only a broadcast it is enough to make a panicked Nex run off and go to the source, hearing him say that Naoabi had been infiltrated by mercenaries and that there are Sequence Destroyers there to hunt them down. A particularly gruesome display of him killing a Liberation Sector captive with Leviathan is enough to send the boy running off again, this time in fear when Akuhei warns that the longer he runs the worse it'll get for him. A fleeing Nex's emotions cause his Grimoire to react with something in the alleyway as he feels the ground fall out from under him, breaking an unseen seal, and drops down beneath the city. 
When he awakes, he is greeted by a girl who was hiding here. To his alarm, this is actually his friend from the refuge who he thought died during the events of the incident with his Grimoire in Shukuto. As Nex reveals his identity to her, she is equally relieved to see him safe. Learning from Nozomi that she was brought to Naobi after the incident leaves Nex to wonder how this occurred, though Nozomi assures that she wasn't brought under any harm and that she is living here peacefully. After introducing her to Cerea, Nex recalls Akuhei's statement on the fate of those who decided to help the mercenaries or Nex, and he worries for Nozomi's safety. Nozomi is quick to reassure him that she can handle herself, and she keeps herself sealed off from the rest of Naobi. Recalling that they need to get back to Imyo, Nozomi suggests they leave, and Nex promises to come back once he's stronger, while Cerea wonders if she would join the squad one day. As they head out of the alleyway, Nex is disgruntled to come across Serza and Arcius who saw them earlier. Attempting to use the excuse that they're teenagers who snuck out again, Nex says they have a hideout, which raises Serza's interest as he tries to get Nex to show him this place. Nex insists they need to leave before they get into trouble, and Serza lets him go, but not before touching his arm which was cut by the fall he took. 
As Nex and Cerea head back for Imyo and the mercenaries, they soon discern they're being followed by Arcius and Serza and do all they can to lose them, wondering why they were tailing them. Nex hides away with Cerea as they wait for them to pass by, before Nex realizes the intention of Serza touching his arm was to give blood to Arcius to test it for abnormalities. Cerea patching up Nex's wound so the Blood Reaver could no longer track traces of his blood. However, Nex understands that they've been figured out and needed to leave before it was too late. Nex and Cerea rush back, where Nex receives a short scolding from his guardian for running off, while the teenager admits his fears and hatred of Akuhei, believing he'd do something similar as he did in the Shukuto refuge when he found him. To his relief, Imyo secured a verification key card and they could use the transport to escape the Marshal's city. Only, once they attempt to utilize the device, they're ambushed by Faulhier and Rythrean, who were notified by Serza of their likely plans to escape. They trap them on the node, intending to use it to send them to Iwasu instead, with Rythrean interfering with Switch's hacking technology with her capabilities as a Prime Field Device. This leads to the young Nex using the Azure's power to make a stronger interference and break away to challenge Rythrean in order to buy Switch time to create a new program. With their main target no longer on the node, Faulhier would step in to fight Nex, and the young male is hardly capable of fighting and focusing the interference. Switch manages to write the program just as Rythrean regains focus, and Nex hurries back to the node. Mistaking his action for giving up, Faulhier tells Rythrean to send them to Iwasu. With Switch's program activated, the node malfunctions and scatters the group.

In the Pilot episode, Nex begins trapped on an airship headed to Kagusutchi to drop him off in the Research and Development sectors. It can be assumed by the Captain's dialogue that Nex was captured somewhere between Kagusutchi and the 12th heirachacal city. Before his eventual escape he has a few moments to reflect on a past situation that caused him to develop the words in his mind "Never forgive" and "Never forget" showcasing his disdain to the world. Eventually he breaks free displaying a dark Azure's power and causes much havoc upon the ship, slaughtering a large amount of NOS militia stationed there in charge of his transfer. Nex breaks out and takes out the airship before his escape to the ground levels. 
He meets his acquaintance, Legna Alucard there who had been the one to request Nex to come here. Nex believes she called him here to help him find something of interest, though instead she informs him of a girl within the city. Nex seemed to understand the importance of her inclusion, and after thinking on it he decides to go look for her and get her away from Sequence.
Though Nex doesn't appear in the story the rest of the episode, two people named Lukain Necaros and Mysteria of the NOS seemed to have been tracking him.
Upon arrival to the city in Episode 2 he has a nightmare where he'd been severely injured across his entire body, he knew he was dying and was being cradled by someone to an unknown location. In the nightmare he begins to lose all sense of feeling until a kind of energy shoots through him and jolts him awake when he hears a sinister voice echo in his mind. Nex later awakens in real time, coughing out blood to find he'd passed out in vicinity of a peer dock. He keeps a thought to himself about finding a man and forcing him to talk regarding that nightmare's events and the reasons behind it. 
He returns focus to finding Myri, but Nex's search ends up getting him into an unfavorable situation where a citizen reports him to the NOS. To his surprise does a man who was a beastkin decide to help him out and get him out of the area. At the end of the episode a squad of NOS soldiers are following him, detecting the signal off of the beastkin Nex was with.
In Episode 3, Nex leaves with the Beastkin to arrive into a house within Area 3 of Kagusutchi's sub levels. He talks to the Beastkin for a bit learning his name to be Rau—His father being friends with one of those in the Third War of Armagus named Mordecai. Rau describes his father as a bit of a loon to Nex, and says he believed in many outlandish matters in that time, but Nex doesn't seem to say much to it. He reiterates to Rau that despite his father having wish for an ends to the wars between LS and NOS, that he's not here to bring peace. Rau is able to accept whatever road Nex decides upon and lets him rest at his house until he wished to head out to find the girl Myri Kukiyona. He passed out for a few hours to be all but awoken by pounding on the door by none other than the NOS seeking him. 
Nex decides at first to fight the NOS members that barged in on Rau's residence that night in Episode 4 prepared to cut all of them down after he recalls several of his own memories that angered him. Rau then intervenes bringing up the subject of Imyo, a man who'd taken him in after the incident surrounding the awakening of his Azure's power. Finding that Rau knew about Imyo he had apparently been a part of a merc force outside of the government, and Imyo had been prepared for the consequences that would ensue after taking in Nex because Imyo along with others believed that the "world was waiting for him" due to having the Azure. Nex finally decides to listen and heads out leaving Rau to fend for himself.
Nex hurries off to find Myri and ends up being found by another member of Sequence, named Kiryos Hikamigawa. Kiryos explains himself to be an assassin with his target being Nex. The two face off for a moment while exchanging words about the world around them, resulting in Kiryos's defeat once Nex released his Azure partially. Nex however decides to spare his life telling him to figure out for himself why he let the man walk away alive. Nex leaves the premise and hurries to the upper level of the city where he finally finds Myri, who frantically panics upon seeing him. Nex mentions that he was here to keep her away from Sequence and she'd "help destroy them with the power they desired from her soul".
In Episode 5 Nex speaks with Myri as he attempts to get her to come with him on his road, telling her that she was vital to his own success as well and he couldn't allow her to be within Sequence. After a lot of arguing he manages to get Myri to come with him after explaining that he knew what was being told to Myri about her life wasn't true and only outside of Sequence would she be able to find the truth. Though he doesn't say how he knew all this and simply gets her to hurry along so they can get going. Nex decides to travel back around to Rau's home in hopes of talking to him more about Imyo, before returning to Legna. However Myri ends up passing out on him and Nex takes her into Rau's home, only to find out that the NOS's General, Yami Akuhei and Mysteria had arrived first and was expecting Nex. Flashing forth a tortured Rau, Akuhei tells Nex that Rau's life is in his hands. The episode ended with Nex staring down Akuhei as he tries to decide the best action to take.
Picking up right after episode 5's cliffhanger Episode 6 Nex and Akuhei speak about various matters concerning one another. Evidently by his words Nex is known to not let anything jeopordize his road. Nex responds with the fact he simply didn't care. In a stroke of surprise does Akuhei call him out for the fact Nex is in fact lying about not caring about Rau. In fact he mentions that because he "Knows what he feels and thinks" that its impossible to hide the truth from him and says he doesn't want to see him die. Nex becomes infuriated when Akuhei does this, and when asked to give the Divine Vessel over and he'd let him walk, Nex refuses and challenges Akuhei and Mysteria. Somewhere in the middle of the battle as Nex becomes more angered does Akuhei kill Rau which causes Nex to reflect on a time he couldn't forget.
Apparently in the "Incident" he'd remembered the streets ran red with a pile of corpses, someone standing atop them in the shadows wearing a grin and laughing. When Nex comes back to he hears Rau's plea for him to leave, but Nex simply goes at the fight even harder. Nex is gruesomely defeated at the end of their fight by the Nex Exitium Leviathan. Akuhei mentions that had he not been "holding back" by not using his Grimoire then he might of been able to give a better fight. Until he does he wont win his fight or stop something Nex refers to as the "Heart of the Foe". Nex refuses to talk to him anymore after that point, even when a topic of Imyo and a part of his childhood with him was brought up concerning another child being raised along with him there. Legna intervenes before Akuhei could take the two into complete custody or harm them further, and Nex is left to reflect on his own alongside Myri in the boundaries to the middle levels. The two get into an argument in which Nex mentions him being blamed for everything wasn't new. Soon Byakai Torayuki arrives and curious about Rau; Nex passes the info that he was just killed.
Nex speaks with Byakai and Myri in Episode 7 and revealed that he apparently saved Byakai from a Sequence Destroyer outside of Kagusutchi. As Nex is brought up to speed about the situation regarding Kagusutchi, the LS and NOS he reflects on a moment where he'd been sandwiched in a time of war as well when he was younger. An incident occurring before hand, when he awoke his power. Apparently he'd met Akuhei, but the memory is cut short as Byakai snaps him out of it.
Shortly after does Legna appear and inform Nex that he would have to watch over Myri, and help her find the truth for herself and prepare her for what was ahead; much to his disdain. Apparently only his road would lead to her finding the truth, again Nex becomes disgruntled to it. After Legna had finished scolding him for facing off with Akuhei, she mentions to not use the grimoire around Myri if he could help it. She ends with telling him to go to the restricted area where the seithr generators and converter lay if he wanted to learn more concerning the NOS's projects. Nex travels towards the upper levels where it was hidden between a branch and the populated city areas.
Nex heads to the upper levels of Kagusutchi in Episode 8 as he makes his way towards the restricted areas needing to weed through the populated city first meeting someone who he wasn't expecting in the process. The NOS's Brigadier Siegfried Schtauffen seemed to have connection to him years prior. The talk quickly takes a turn for the worse when Nex remembers he had to leave when their caretaker Imyo told him he had to leave, being unable to protect him from what was soon to come. Nex took note that Siegfried was still embittered by the fact he'd left. In truth Nex didn't want to leave, and Nex attempts to apologize in a way, but he doesn't have it, proving to Nex that he was wasting his time here. Before he leaves he learns that Siegfried joined Sequence. Nex utters his displeasure in so many crude words, as he demands a fight from him, wanting him to show he would be able to handle what he'd thrown himself in.
Ultimately Nex refuses to finish the fight, telling him despite the fact he'd grown, he was weak in the soul and mind, unable to control his anger or azure properly and he refused to acknowledge his cause that Imyo raised him for. Nex leaves him on those words, later toward the end of the chapter venting out his anger on the subject and swearing to make Siegfried leave the NOS. He also shows great resentment towards Akuhei who earlier that day, hinted at Siegfried being around but Nex didn't piece it together fast enough. Feeling he was behind this someway, Nex then angrily affirms to himself that he'd make Akuhei pay before he heads back out into the deeper parts of the city closer towards the branch.
Continuing to make his way through the areas making steady progress to his target, Myri decides to have the two take a break in Episode 9 as she goes to the archives to learn anything about her family. Before hand the two discuss a matter of what the two cared about and for some odd reason it makes Nex see Myri as "someone else" as he hears the voice speak to him to never forgive or forget. Nex quickly moves subject and brings Myri to the inside areas of the military docking station, allowing her to find an archive for her to learn about her family after offing a patrol and taking their access cards. Nex explains to Myri that she shouldn't believe everything she was told, telling her the government made the first move on him by attempting to capture him for his potential with the "Power of Azure" before he even obtained the grimoire and they were the sole reason for him doing any of this. 
Nex eventually leaves however after he gets into an argument with her about matters she was learning of and his clear disagreement towards certain things.
After a while of awaiting he begins to reflect but is bothered by someone who became adamant about him being the "Beast of Sin". Nex denies it at first, and the man mentioned that he'd make a perfect lab rat. Annoyed by it, Nex eventually comes to a realization that he was in fact a member of Sequence: a Lt General working closely with Lukain. The man who called himself Fasado forced Nex into a fight, pushing him to use the Azure's power of which he showed no fear to go against, unlike most. Nex appeared to be winning until Fasado poured power into Byrus and struck him hard with a thrust. Telling him that he'd make him a personal test subject and use him to kill off the man he sought: Mujihi Mazio, Nex releases his Azure further out of spite. While he gained advantage once more, Myri knew something was off and after she went to where Nex was, and she intervened in the fight begging him to listen. In a twist does he actually listen to her and stop himself from fighting any further. Nex coming out of it as he realized he let emotions get the better of him yet again. Nex mentioned to the man that he didn't want to see him again or he'd make him regret it, and leaves with Myri afterwards returning focus to getting to the branch and the restricted area. 
In Episode 10, Nex comes into the 4th area of the city after his encounter with the Lt General Fasado, hoping to find a moment for rest as night closes in. Overhearing talk of the area being in abuzz about a recent attack, apparently with a NOS building being targeted and destroyed earlier with its personal all but wiped out. The government pinning blame on the two forces of destruction "Beast of Sin" and the "White Demon" left Nex with a bad taste in his mouth as he awaited Myri to come out of one of the stores. Downing his food at a quickened pace, the Beast of Sin left the area intent on heading back onto his road. 
Within all the confusion of the area, two members of a mercenary force Red Thunder he'd heard about earlier ended up ambushing Nex. Mujihi Mazio and his partner Bitoku soon after a fight born of misunderstanding decided to hear Nex out. The irritated rebel explains he fought the same man Mujihi sought out. After conversing about Mujihi's situation, including the Chaotic Element and Fasado, they hear a commotion in the area back in the city from the warehouse they were within. Myri running off in a rush causes Nex to follow disdainfully.
The women named Valetha Deumos appears who searched through the areas for Nex in specific, leaving a trail of carnage to do it. With the women desiring Nex's aid in her endeavors, offering him the opportunity to join and never have to be concerned with the government again—to this Nex strongly refused saying to be on his own road even if they both hated the world, with choice being one of the few things he had left in the world he refused to make it to help her. Valetha retorting that everything in the city going on was "for mission over him", Nex decided to face off with her alongside the duo of Red Thunder.
Shortly into their conflict with Nex and company winning, the White Demon decides to intervene and manages to scare off Valetha, the red hair mentioning that she'd see Nex again. Nex and Sylar are shown to have a connection as allies of sorts, Nex becomes concerned with why he's here and learned that he'd been chasing someone here who targeted Kagusutchi. As the White Demon led the group to the sight of the recent attack, Nex comes into contact with a strange black mass that looked like a human who was now purely a corpse of clumped and concentrated seithr. He seemed to recognize this strange mass, and destroys a crimson diamond-shaped remnant within it before asking Sylar if the one he saw seemed different from others. Nex seemed to be a bit uneasy upon learning the answer, but shrugged it off and leaves the building after the discussions.
Afterward, Nex tells Sylar that he'd have to do things on his own despite their history of working together. With a comment dropped by Mujihi for hopes that Sylar and he could one day be allies, Nex puts in that he didn't trust anyone enough to put any real faith in them as an ally and leaves after, reflecting on the strange mass he found in the building. Nex bringing himself back to the warehouse then falls asleep after explaining to Myri why Valetha referred to her as the Foe, Nex unable to finish his explanation of her weapons Norai Stigma as he passed out.
Episode 11 hinted at Nex having a struggle within a nightmare or memory. He fought to wake up saying that it was "Too dark". As Myri woke the struggling Nex, he reached for his locket and somehow calmed himself from it. Explaining it to be a memory more than a dream, it was one of the few times Nex had felt fear as reality. 
Revealing that he had been in a place of what he remembered to be peaceful, he was with another who had given him the locket he now carried as a memento, and does genuinely care for this person. Apparently something had taken place that a younger Nex couldn't prevent, and he escaped from whatever fate occurred but promised he'd go back. As Myri asked if it was during the time he knew Siegfried, Nex replies that it had been before, though he in truth wished both times ended differently.
The two then headed into a sector within area 4 of Kagusutchi owned by the government, now abandoned. Nex seeking info about the Azure Interface Primefield though he finds none. As Myri runs into her friend Yumiko from the NOS, Nex stumbled on a strange container that sets him on edge and he prepares to destroy it. Having seen one of them with Siegfried when he was younger. Before Nex can destroy it, Yumiko manually opens the pod to prevent the action, and rather than one of those things being within, a girl is in its place surprisingly. At the end of the episode Nex is preparing to face off with AIP that were stock models left in the facility who detected the opening of the pod. 
Within Episode 12, Nex defeating the AIP that attacked him revealed an ability he had to destroy their Azure-laced cores, as his energy corroded the life of the core and left it to collapse ending the AIP's life. A second one he snared the core from, and interfaced with their memories utilizing his Azure—Nex explaining that he had a connection of sorts with them. Seeing what they did as a bloody conflict erupted here where other types of AIP were stored and likely captured. However, these being mere stock model copies of "Fours" didn't give him anything he was after in terms of memories, and he leaves after getting the girl who came from the pod out of the facility.
After the girl is found to be Miwa a 200-year visitor who contained a Power of Azure that was highly pure compared to his own, Miwa decided to try and use her Azure to help him. Nex refused and kept his own power hidden from her fearing what it'd do to her to observe how dark his soul and power really was. Shortly after Miwa mentioned her desire to help the world with her power. Again reconfirming his stance as enemy to the world, Nex retorted that he was only interested in destroying Sequence's "Protection" over the world, as the only one who could. He mentioned that he wouldn't get in the way of those who saw differently, but didn't appreciate having ideals slammed down his throat. In incident, his harshness caused Miwa to cry, this being a huge weakness of Nex's caused him to reflect on a brief moment he "Let his anger and grimoire get the better of him" with Siegfried in the past. And, in rare form Nex apologized to Miwa before he told Yumiko to be careful of the three higher ups if she was intending to take her to the NOS with her.
As Nex turned attention back toward the 5th area where the NOS Branch would lead him to the Restricted Area, he and Myri run into a demon of a man who claimed to be in the NOS and apparently knew Nex from a time he wasn't as fearless as he was now. It appeared to be a one way recognition as Nex failed to relate him to anyone he'd seen before. Overwhelmed by the amount of power this man actually contained, Nex is pushed to telling Myri to escape and once she does, he no longer concerned with radiating its darkness around her, uses a large sum of his Azure's Power and defeats the man. Nex then decides to look for Myri and reunite with her before the NOS finds them again.
In the middle of Episode 13, Nex is found by Reiga Sorairo and Akari opening an encounter that revealed his disdain of the Azure Interface Primefields. Having a particular anger with Akari for some reason for the similarity to one Type Four he'd seen during the "Incident" where he received his Azure Grimoire. Dropping comments that it infuriated him to see "Her singing and smiling" as he apparently near died that night. As Akari seems to sync with this memory, after saying how she didn't want the man to hate her, she changes personalities and summons her unit as she fights Nex while she mentioned gleefully and childishly that she never wanted their pain to end. Nex ends the episode mentioning that he'd destroy her just as she did to him.
Episode 14 picked up into Nex’s fight with the estranged Akari, as Nex tried to get her to say which four had the memories in question, she spoke a cryptic message saying that all of them do, and all fours “seeking the same as their beginning”. Attempts to get further info denied to him, he released his power as he stalemates, and sets his mind to destroying the AIP. Reiga swiftly got Akari to notice what was happening, but Nex manages his attack anyway, and having taken a lot of energy to recover her senses, Akari falls unconscious on impact with the attack, just avoiding the fatality of the blow. Nex continued to show enmity towards the AIP, until Reiga intervened in the battle surprising Nex through the use of a light-based azure energy. Before they could get into a conflict of their own Myri showed up with Legna and halted the battle, before the small group was transported out of the area. 
Coming out after the conflict, Reiga remained confrontational with Nex concerning how he’d attacked Akari, but Legna silenced the argument and scolded the two. Nex made comment on Reiga’s desire to change the world with his power, but as Nex tried to explain a majority of the government likely didn’t care, Legna again quieted him telling him it wasn’t his place to sway his opinion right now. When Kiryos and Anna appeared to join the group, Nex remained completely silent, simply listening to the conversation. 
However, when Reiga asked him why he wished to destroy the government that served as the world’s current protectors it led to him reflecting on how he believed the world truly was: A world of near perfect control where souls were trapped in a synthetic paradise a veil to the dead world underneath it. A world that he despised and wished to destroy. However to the others he simply says he had his reasons, but wouldn’t share them. Shortly after he’s pulled away to speak to Legna in private addressed later on.
Returning to it later but leaving the majority of the conversation off screen, Nex heard something that raised his attention and left him perturbed. A cauldron housed in Kagusutchi he mentioned that in the controlled cities there were still ones left utilized in the Third War of Armagus to summon something. Despite being warned and again affirming his choice, he said he’d destroy “it”. Towards another matter Legna mentioned, Nex said he’d leave it up to “her” since apparently from what he was told it sounded like he wouldn’t have control over the situation anyway.
Nex isn’t seen again until the last part of the episode where he runs into Valetha and a Minister of the NOS named Keil. Soon feeling urgency to get back to the others, he’s unable to as Valetha blocked off his path and challenged him.
Within Episode 15 of Control Sequence, Nex resumes his fight with Valetha both exchanging blows at an even rate with Nex taking a strike from Iblisa’s shot that dissolves his skin revealing, only briefly, a patch of pure dark substance beneath it. In crude manner, Valetha mentions her liking of that “look” saying she’d burn away the rest of his humanity. In rare form, Nex harshly mentions his humanity had “died” a long time ago, before he unleashes a powerful attack to turn the tide on his foe. Soon after Nex realizes the kantana Valetha debates on wielding was a weapon designed in the Third War, but before she is able to utilize the sword on Nex, their battle is interrupted by Legna who quickly prevents the activation of Lilithal and traps her within a barrier, allowing Nex the time he needs to slip away from the area and get back to helping Myri.
Later into the episode, he resurfaces to interrupt the fight between the group Myri was within and stops the Seithr beings from killing her off. During the encounter Nex learns that their apparent leader named Zaezel awaited him within the central area of Kagusutchi nearing Area 1. Zaezel having been behind the event which the black mass was discovered in Episode 10. A comment dropped by the beings mentioning that the group would make a “good meal” for the Grimoire causes Nex to became angered and the rebel decides to take the beings out himself, showcasing a clear disdain for them as he calls them “worms”. Engaging in a difficult fight with the beings he ends up taking a critical injury through his left shoulder as Sithus impales it. Nex then manages to utilize his other arm and fills it with a powerful energy, the blade of Necros gleams viciously in reaction, before he runs Sithus through with the weapon. As though on command, the blade's energy causes the core of Sithus's life force to dissipate on contact. As the energy is consumed by Nex involuntarily it also heals the wounds across his body including the most gruesome he’s received in the fight. 
However, oddly, the  remnant left behind after Sithus is defeated causes a reaction within his Grimoire causing it to “stir” which triggers an occurrence where Nex experiences difficulty keeping it at bay. This occurred when he was younger and with Siegfried having encountered a Seithr Being. Him receiving too much energy caused him to go into a state of “overheat”, unable to do anything but wait it out. It was both agonizing and took immense effort to hold it out against the “desire” his Grimoire had. Not expecting to have the grimoire stir so suddenly, it fills his mind with destructive negativity. Nex remains in place while conversing within his mind or perhaps something only he could hear, as he awaits the storm of power to blow over.
Mysteria however soon approaches despite Nex’s harsh and clear warning, seeing in his eyes a thing darker than black and hearing a collection of ere statements. As she comes out of it, she falls back frightened and unable to tear her eyes off his glare exclaiming in horror he was everything dark, destructive, evil and chaotic to existence itself, to which Nex responds with no sense of denial nor confirmation. He doesn’t respond to her when she asks why he existed either, this tribulation eventually leading to the intervention of Reiga and others to pull a mystified and terrified Mysteria away while Myri somehow negates the overheat of negative Azure energy and Seithr after touching Nex on the head and releasing a strange aura into him which causes his emotions to briefly calm down.
Shortly after, he’s shocked to see the one he’d been waiting to cross show up: Lukain, Marshal of the NOS himself which upon entering, ends the episode.
In Episode 16 Nex continues his encounter with Lukain and learns a few answers to his questions of the past events surrounding the events of his Grimoire being infused into him. Supposedly the Grimoire wasn't the doing of Lukain's or the NOS at all, but an outside force with a Rogue AIP. However Lukain did mention he sent in the initial forces to capture him after said event, resulting in the death of a friend of Nex's. He openly admits being the one to strike the command to kill Imyo who Nex was with for a large portion of his life—in turn this event generated turmoil in a younger Siegfried's life.  Nex left so they'd be able to get away, and mentions how ruthless it was of them to "hunt them down" in the process taking advantage of Siegfried's helpless state. He then immediately lashes out, telling the Marshal he'd bring him down beyond hell. His anger clearly gets the better of him as he'd have no idea what the Marshal could be capable of.
The battle occurs later when it hasn't turned in either direction a sinister voice begins conversation with him to get him to utilize his BlazBlue. But in the end Nex refuses, continuing to keep it dormant, and instead unleashes Vow of Destruction. Even with the power increase though he's unable to defeat his foe, much to his surprise. It costs him the fight when Lukain utilizes energy from the Boundary directly, making it his own and catches Nex off guard as it depletes his energy and only serves to give Lukain stronger dark magic-based power. He's then stuck listening to the conversation Lukain has with Myri with her deciding, much to his disdain and anger, to return "home" with Lazarith. She's asked to utilize the newly realized power of her soul to quell Nex and his Azure. Nex explains the last of his position and asks Myri to show him that there "was no hope in her, him or the world" and ends the episode, demanding her to end his fight. 
Nex seems to prepare for what would be an ultimatum in the beginning of the finale in 17. Myri, to his surprise, stops using the attack all of a sudden. Having seen a strange occurrence where Nex kills her and he undergoes a change, she halts and apologizes for the fact she can’t be the one to remove Nex’s belief from him in fear of this actually happening. Although confused, Nex seems to calm down for a moment after Lukain leaves the central ruin area outside of the 5th area, and is approached by Kiryos after who wished to know more of what the “truth” was surrounding this world. Nex begrudgingly decides to tell them what he could.
Later into the episode he talks to them, mentioning that seeking the truth makes one an enemy of this world which seems to have an idea and gives roles to people, a soul that goes against this world’s current order and “Design” for their soul is apparently incredibly rare. Nex doesn’t say it directly but it can be assumed he’s one of those people along with Myri. Myri then comes into mention of wishing to help Nex by learning more and hopefully helping him. Nex mentions that he’s only here to get her to know what she’s capable of and learn the truth of her own soul, and once she does he’s not going to let her follow him anymore though why that is he doesn’t say much to Myri’s hidden dismay. After hearing from Legna who comes in on the conversation that the 5th area was being harvested of soul energy, it seems to cause something of an upset in Nex who quickly moves toward that area.
Within the area’s entrance he comes in contact with an enormous amount of seithr, as well as the two members of Red Thunder, Mujihi and Bitoku. Nex warns Nicaiah that if she sends the two to try and stop him, he’d kill them, making it clear that whoever tried to stand in his path directly, he’d destroy. He ultimately decides to leave Myri with them, as he didn’t believe he’d be able to fight and watch her at the same time. However at first the girl tries to follow him, but Nex responds sharply in cold anger to the comments she makes such as “You’re coming back right” and “You’ll keep your word right?”, causing a harsh reaction from Nex, who says to stop that “meaningless talk” and that he’d be back for her later.
Nex on his way ends up encountering an unlikely face, Serza formerly of the NOS’s Sequence Destroyers. Nex quickly lashes out at him on sight, indicating the two have something of a bad blooded relationship through their dialogue. Serza easily pins down Nex with the blade “Ophius” and made a point to jokingly mention Nex’s bad temper would cost him his life, but then changes tone that he was only kidding, and killing Nex is pointless in this world. Serza quickly cuts to the chase and asks him if he wanted to help Siegfried, because he couldn’t “last time” Nex annoyingly retorts he should watch his wording. Though the two weren’t enemies at the moment as Serza points out and tells Nex that Siegfried is in the area fighting Zaezel, as instructed by his former superior Akuhei. This immediately presses Nex into action as he ignores Serza and heads after Siegfried’s location to try and stop him saying to himself that “He wasn’t going to die there this time” if he had anything to say about it—believing that Akuhei’s purpose of sending him there was to get him killed.
Finding Siegfried and Reiga who were standing off against Zaezel pushes Nex into anger as he tries to stop the Brigadier from fighting the apparent leader of the Seithr Beings.
The beginning of the next episode has Nex telling Siegfried to leave the area while he dealt with Zaezel, however the Brigadier refuses in usual fashion. Meanwhile, Zaezel explains to Nex that he shouldn't be wasting the time provided on idle chatter and he'd been waiting for him to show, calling him the "Strongest" force of destruction the world had to offer, but Nex doesn't say anything to it instead demanding to know what this "Lord" of his was. Siegfried then steps back in and asks the being to die, causing Nex to again step in and try and keep the attention on him in effort to keep the Brigadier out of the fight. In the end its a futile attempt as he makes it clear he was going to fight, as the two argue and mirror each other's readying stances in the middle of preparing to fight Zaezel—Siegfried's comment of him "working to make Nex's life as fun as it could be" pushes Nex's patience over the edge and he gives up working with him openly stating he made it impossible right now. As if the entire world around them no longer mattered, the two focus solely on each other. 
The two engage in combat with only the other as their rivalry seems to become quite evident in the two's dialogue. Nex had grown frustrated with his recent choices and lack of attention to anything except for himself, forgetting and throwing everything they once knew away. Nex has a bit more difficult time fighting him though with Siegfried's strengthened resolve but the two kept an even fight while expressing their respective detests toward the other. Siegfried had flat out lost his desire to change anything after Imyo's death and believed Nex had abandoned everything himself as well. When Nex mentions in the middle of the fight that the blue haired man was letting his anger command him, Siegfried laughs, saying that he's the last one who should be lecturing about anger and apparently Nex had lashed out angrily at a younger Siegfried for touching the locket around his neck. Nex's retort is that he told him not to touch the locket, but Siegfried never once listened to Nex, just like now. 
The two's fight lasts through the majority of the episode and eventually Nex is countered to the point he sees a need to gain more strength so he utilizes Vow of Destruction in the hopes it would do so. However the two continue to match each other blow for blow each pass, Siegfried somehow managing to keep up with Nex even in his powered up state. Eventually Siegfried doesn't wish to lose to Nex so he releases all of his remaining strength into a devastating blast sending the both of them opposite sides and smashing them into the faces of the structures around them. Nex angrily mentions he was an idiot for trying to destroy them both, while Siegfried asks why he couldn't just "die" and he always hated losing to him. Calling Siegfried childish once more for his attitude, Nex mentions he no longer cared what he did so long as he believed what he was doing, then Nex wouldn't stand in the way of it anymore. This acknowledgement only seems to make Siegfried complain more—Nex retorts he can't win with him, and instead tells him to stop giving him a headache like a kid would.
They soon realize Zaezel had failed to be dealt with by Reiga. With the two's energy gone from their feud they're unable to prevent Zaezel from taking advantage of the situation as he prepares to finish Siegfried off completely saying that "someone like him isn't needed in the world to be created from the ashes of destruction". Nex in rare form becomes nervous and desperate when he's trapped in manipulated Seithr which solidifies around him making a prison of crystallized black material similar to his grimoire. It was to preserve him from the destruction that would occur in the city once Zaezel finished harvesting it.
Nex comes to an ultimatum refusing to let things "End" here. Despite his apparent decision to never use it again—Nex utilizes the true form of the Prototype Harvester Zaezel had in the form of the "Soul Harvester". Gathering the souls of everyone and massing into one singular core of negative force, souls and seithr—its consumed into Nex he experiences immense waves of pain as he unleashes the grimoire which causes him to undergo a strange transformation on him infusing that power and seithr into himself the grimoire's form more evident on his body, and veins of crimson shinning through. As Akari mentioned to a wounded and astonished Reiga that this was the "Evil" that Nex existed as, Reiga mentions it was from "Beyond the Gates" as Nex roars in power and hatred. 
In the end part of Verse 1's finale, Zaezel and Nex fought head on head for a time, Nex easily having advantage over him until the Nefas used his harvester to release the energy into himself and made his actual form manifest. Nex realizes here he isn't an ordinary seithr being, and Zaezel mentioned that he was in reality one of the Azure Sin Subjects (Nefas for short) "Imitations"  designed by one of the "Magistrates" evidently Nex heard of them. Using his Norai Stigma as a conduit, Zaezel attempted to destroy the area and kill everyone in it, Nex's response to this was to utilize his grimoire's power over destruction, summoning beasts as he grabbed the black mass the Norai Stigma became and tore it apart, and absorbed it with "Devouring Oblivion" an enhanced distortion. Inadvertently he saved the group from death, but Nex had mentioned he only did it to absorb the energy for more strength and their lives weren't really his concern. The end result left Zaezel severely wounded, in which Nex was about to destroy, however Siegfried possibly tired of sitting around uses Nex to gain height and took the finishing blow with his own distortion—however it became apparent he wasn't capable of defeating Zaezel permanently, and Nex angrily replied for Siegfried not to stand in his way or he'd "kill him as well". It shocked Siegfried to a degree, as he didn't expect Nex to ever say that, clearly pointing out that the Blazblue had an alteration effect on his mind.
Myri and Sylar then entered into the conflict where Myri quickly goes to Nex, however in the mindset of the grimoire Nex seemed hostile to her, Myri mentioning that his eyes showed off a "Unstoppable hate and destructive desire" she then stops Nex somehow with the power she'd discovered earlier and quells the grimoire's effects. Zaezel had fled, much to Sylar's disdain as he asked him why he didn't finish him off—however, Nex doesn't answer as he enters a comatose state after that for a day after the events of the 5th Area.  
==Verse 2: Primordial Awakenings==
Nex wakes up in a medical room of a recently deserted NOS station in the 5th Area of Kagutsuchi's levels. After the conflict with Zaezel he'd passed out from the physical and mental strain. He has a memory during this time where he is being recovered from a gate and falling structure by a boy he recognized as Niko. This being shortly after the time he'd received his Azure Grimoire. In it, Akuhei mentions that Nex didn't remember him yet, and explains that this chaos was only the start of much more to come. 
Back in the medical room, Nex wakens not understanding why he was shown the night of the incident after the recent release of his Azure Grimoire. Nex is told by Reiga he'd been asleep for a day, and Siegfried and others had been here waiting for him. His ally Sylar, however, didn't stick around. Nex immediately becomes angered with Siegfried for questioning him about the energy he released from the Grimoire and Soul Harvester. Nex explains to him that the energy is from a source beyond control, and Zaezel uses something similar on a lower level. It ends with him warning to Siegfried to not pursue the sources of that energy or use it again as it can destroy ones mind to do so. After Siegfried bluntly assures Nex he had no interest in that, Nex leaves to pursue Zaezel and head back towards the direction of the main branch. 
While he waits for Myri, he is disturbed by the Lt Colonel of the NOS's Militia Forces: Mysteria. She immediately addresses him by his title saying how despite his recent efforts against Zaezel, he still was an enemy to her—and Nex assumes she wants a fight. As the two insult one another, a confused Myri exits the building to see her friend and Nex arguing and combat-ready. Myri soon quells the fight, and Nex reflects on his road ahead. The rebel makes the resolve to end things before they begin—and Myri comes up to talk to him about why he stayed outside interrupting the man's thoughts. Nex mentions that he didn't do well in groups. Nex quickly shifts topic though and becomes upset at her for not listening and staying with Red Thunder's Mujihi and Bitoku when Zaezel was around. Although it gets turned on him when the topic of his Grimoire and Soul Harvester is dragged up and how it changed Nex temporarily—Nex mostly brushes the topic off not wishing to talk about it, instead he mentions he didn't want things like Zaezel getting what was inside of Myri.  
Legna soon intervenes on their conversation, much to Nex's annoyance. She mentions to him the dangers of activating the grimoire again, as well as the risk of leaving Siegfried alive. Nex replies mentioning that he refused to let Zaezel kill him. If Siegfried became an issue, Nex swore he'd deal with it himself. He's then introduced to the spirit of a beastkin Koyoto much to Nex's surprise—and hatred—due to being a ghost. Koyoto to Nex's surprise is apparently Imyo's friend. But due to Nex having no recollection of the beastkin in his memory, he denies him and leaves toward the branch in an upset at the idea of him helping due to the painful memories it drags up in his mind surrounding his dead caretaker.  
Nex is seen once more with Myri as the two head toward the military district and research levels of the city, but a conversation is sparked between the two where Nex questions her odd silence this afternoon—Myri says it shouldn't matter to someone like Nex who never talks anyway. To that Nex says he stopped talking awhile ago, leading to Nex explaining that if it were left up to him he probably wouldn't be taking her with him. That perks her interest to why, and Nex explains he isn't the hero who is saving her from Sequence—the truth she figures out because of Nex will likely destroy her. Nex also drops mention of people who he's a bit nervous about having their existence brought to light due to a careless mistake, which explains why Nex remains cautious at all times.
A Seithr Being as an envoy for Zaezel intrudes and tries to explain to Nex the futility of protecting her, saying her time will begin to run out when their lord arrives—but Nex simply kills it rather gruesomely and asks for a face to face next time after mentioning that he wouldn't let anyone kill Myri. While Myri freaks out over what was said by the seithr laced creature, Kiryos joins after the brief fight with the Seithr Being. Nex is forced to move the group away as the noise they made was drawing attention to themselves, and Myri only continues to ask questions and demand answers from a frustrated Nex. Nex mentions that he like anyone else had his own fears but he never showed them, and reassures her though in rough manner. Myri stops her complaints to Nex and then says she simply felt ill after seeing an event with Nex in it, and the black clad rebel tells her to sit down and rest for a minute. However Nex is surprised when she ends up passing out due to another strange vision with Nex in it, and shortly after Nex is greeted by the appearance of his nemesis Akuhei.    
Nex enters into immediate hostility with Akuhei, while Kiryos plays it safe and mentions to Nex to surrender. Nex refuses and demands from the General to know why Siegfried was out fighting Zaezel when it was Reiga's responsibility. The two engage in combat as soon as Akuhei reveals to Nex that he was the one to initiate him into the NOS after he found him broken in his will from the loss of Imyo openly admitting that he and the others were playing him like a puppet and he was one of the last few people Nex genuinely cared about.
Nex's anger came from the fact he couldn't do anything to stop them, shown through a memory with Legna present, she told him that his life mattered more than Siegfried's at the time which angered Nex. In present he says that he couldn't do anything—Nex according to Akuhei convinced himself Siegfried was dead, otherwise, he wouldn't be able to forgive himself for leaving him behind to the NOS. When he made the choice to throw away the two's possible alliance, in exchange to continue his fight—it left Nex embittered by his own choice.
Their fight continued until Akuhei chose to strike Myri, which Nex defended immediately. Despite Nex finally being willing to use the Grimoire, Akuhei counters mid incantation and leaves Nex unable to fight after the vicious assault. Later on into the episode it comes back to them and shows Akuhei trying to get Nex to speak about the changes happening with Myri to which Nex knows nothing of. After Nex tries to get Akuhei to tell him about why the Azure Sin Subject Zaezel was here and what he had to do with what Imyo told him in the past—he's tortured by Leviathan's energy to near death which Akuhei gleefully states wont let Nex's strength return for a while. After Kiryos makes the choice to help Nex, Akuhei reveals a strange red Seithr Core that Nex seems shocked to see. 
After learning that the core is only an imitation- Nex is then forced to consume and absorb the red core due to its similar energy to the Grimoire itself. Kiryos quickly intervenes and forced Akuhei to drop him. After being prompted by Kiryos to leave, Nex takes Myri with him and hurries away but swiftly collapses afterward. Later into the episode during his unconscious state he inserts himself into a past memory alongside the girl who gave him his locket, who is revealed to be Yura. The dream turns for the worse and shifts into a nightmare when individuals alongside the government come and evidently caused Yura's death while Nex was present.
Later on Nex awakens in a furious manner and violently lashes out at Myri for it. He catches onto his actions and stops himself calming himself down and apologizing to her. After being questioned by Myri, and after the girl leaves to find something to tend his wounds - Nex recalls a conversation with Akuhei when he received the Grimoire. A solemnly frustrated Nex is left to wonder why the government had the Sentient Unit attack to take Yura's soul, and he questions her choice to save him. 
==Non-Canon Material==
===Alternate Sequence===
====Arc01:Reaper's Road====
Nex’s first portion of his Altered Sequence has him going after the Gate, apparently after the Azure Interface Prime Field. He has an encounter with Akuhei at an abandoned post where the General attempts to defeat the rebel, after questioning about Myri Kukiyona, who unlike in the canon storyline Nex has left with Legna Alucard. Akuhei succeeds in overwhelming him. Although Nex asks of the connection between the Grimoire and the individuals like Zaezel who have the Harvester, Akuhei doesn’t say. Their conflict is ended abruptly when a pile of the ceiling’s foundation crumbles and lands in front of Akuhei to block of Leviathan.Akuhei commenting its an intervention, as Nex quickly escapes in the time given. 
Immediately after he meets Sylar, his companion from the past. Though Nex doesn’t seem interested in chatting, only how he managed to intervene with Akuhei when the Demon reveals he’d been the one to stop Akuhei, suggesting at some point, his friend had the ability to do so. After confirming his friend’s motives in Kagutsuchi, Sylar makes a comment toward Nex’s mood being sour as usual when Nex mentions he has no current interest in stopping Zaezel’s rampage. Nex and Sylar engage in a friendly bout after, when he says Nex should release his stress. After Nex is victorious, he tells Sylar that the power of the Azure Grimoire wasn’t something he enjoyed relying on, to which Sylar mentions it helps him so he shouldn’t be ashamed to use it to win. Sylar then tells Nex of the situation surrounding the ‘Red’ from the girl Valetha, and that certain people were possibly going after the Eye of Sheol. The comments dropped by Nex at the end of the encounter hinted that he’s had to deal with that power before.
He heads into the urban areas, only to find people being evacuated and soldiers on high alert. The NOS spotting him would instantly try to attack, but Nex gets away and avoids confrontation up until the point the Lt Colonel, Mysteria, puts her weapon at his flesh and accuses him of being one responsible for this and in cohorts with Zaezel. Despite Nex’s saying he wasn’t, Mysteria claims that he was here to open a gateway to the Boundary which would release a high amount of Seithr. Nex doesn’t deny it, seemingly wishing to destroy something in that Gate as he seems aware of the consequences his actions will bring, but states he won’t stop. Mysteria furiously pins the blame on Nex for her friends’ suffering and attacks him saying that the Overseers were correct about him being the enemy of all mankind. 
After his victory, Nex takes notice of Mysteria’s Drive having gained strength, and asks what happened- but Mysteria only says she won’t allow him to make them suffer, and instead strikes again. Nex’s counter is blocked by Reiga who defends his superior, but Nex shows no interest in fighting Reiga for Mysteria’s life. When the girl is mysteriously teleported away, Nex wonders what the Overseers wanted with her, before he decides to ignore it for now. Reiga comments that he shouldn’t bring discord to the people that Reiga cares for, or he’ll regret it later on. Sensing the anger in his tone, Nex warns a path of hate doesn’t suit him, and says someone like that can’t defeat him yet. 
Taking another pathway to avoid further confrontation, the rebel makes his way to the sealed district, a place in use during the Third War of Ars Magus and since shut down for the superior Research District. For some reason, Zaezel is present, with the core he has apparently being part of a weapon to enact humanity’s punishment, and asks Nex if he was intent on stopping it. Nex already seems to know that mankind is being punished for their action with the Boundary, but he says it wouldn’t change anything to simply kill all of them, only make things worse. Evidently it’s a punishment decided in the past by architects, and the beings like Zaezel are revenants of the will and power against the current world and following their role, unlike Nex. Shortly after, Valetha interrupts their talk and allows Zaezel to continue his process, saying that she wouldn’t allow Nex to interfere for now. When Valetha asks if Nex is interested in seeing the possibilities the 'Red' is capable of, she says she is there to guide him, the one who decided to kill the power behind the 'world' and its truth. Nex tells her to back off, only for her to say he shouldn't ignore the problem, and should own up to his choice which upsets Nex briefly. She challenges him saying she'll use Lilithel, a weapon Nex calls a relic. 
Nex is successful in his confrontation with the girl, but the criminal only laughs saying she expected that and mentions it confirms he would inherit something. Nex is surprised to hear from her that the Eye of Sheol's power was already in play and that he'd be why some of those things would come into 'existence' again. Valetha explains an event in the past in which the sacred land of Wadatsumi, and its Gate was accessed after it had been sealed by a Clan keeping the Seithr back. Scientist, one of which was Valetha's father would take advantage of the awakening of the Gate and took a sample of its contents. Later the NOS would seal the contents away in Kagutsuchi. Valetha then mentions the thing needed some sort of 'key' before it could be properly brought into the world, and wonders if Nex will find that key. Nex pieces together Zaezel's intention, to which Valetha tells Nex to destroy the tool that will enact mankind's will. Nex replies that he would destroy both, and reduce Kagutsuchi to nothing if that's what it took.
