## Backstory

After the Demon Slayers and Hashiras (The Elite of the Slayers) defeat the Upper Moons (The Elite of the Demons), they fight a great battle against Muzan Kibutsuji, the King of Demons himself, after a great and long battle, the Demon Slayers achieve a chance to hold Muzan until dawn (Muzan's only weakness is the Sun), Tanjiro, Sanemi Shinazugawa (Hashira of Wind) and Mitsuri Kanroji (Hashira of Love) try their best to hold Muzan against the wall of a building, Muzan creates a big jaw and tries to bite Tanjiro but Obanai receives the bite instead of Tanjiro and saves his life, Tanjiro no longer had the strength to use his techniques so he was trying to hold Muzan until dawn, the moment Muzan sees the Sun he starts to get very scared and then releases his Shockwave Energy Blast technique that knocks everyone down, except Tanjiro who, despite having his left arm ripped off, doesn't stop holding Muzan to the wall with his Nichirin sword, Giyu Tomioka arrives to help Tanjiro hold Muzan, with the strength Of the two, Tanjiro's blade turns red (a red blade slows down the Demons' regeneration), Muzan then spits out a lot of blood and starts to burn more and more, Muzan then realizes that in order for him not to die to the Sun, he needs to protect himself with a large mass of flesh and then expands its body and becomes a giant demonic baby, after which Muzan absorbs Tanjiro into his body and crawls towards a building to try to reach the shadow, the lower level Hunters try their best to prevent Muzan from reaching in the shadow, throwing shelves and running them over with cars, the Hashiras who still had the strength to attack used their breathing (fencing styles that use Total Concentration Breathing) to try to stop Muzan, even with the Hashiras' attacks Muzan still buries himself in the ground to try to escape but inside his body Tanjiro had not yet released his Nichirin sword and was holding it with all his strength (turning the blade red), making Muzan in the form of a giant baby cough a lot of blood and preventing him from continuing digging, and thus his body slowly begins to disintegrate and thus the King of Demons Muzan Kibutsuji dies disintegrated by the Sun, Tanjiro's body was on his knees lifeless, giyu Tomioka (the only Hashira who still had the strength to walk) begins to cry at the death of Tanjiro, the kakushi (a brigade of people responsible for different tasks related to providing support to the Demon Slayers) were helping the injured Slayers who were still alive.

Before Muzan died, Muzan reflected on his life and the way he was always being Threatened by the shadow of death, Muzan then decides to choose Tanjiro Kamado (who was still inside his almost disintegrated giant demonic baby body) as the child who would inherit his feelings, motivations and goals, even though Tanjiro is dead (after all, he suffered many fatal injuries during this battle) Muzan deduced that Tanjiro's cells were still alive and put all his blood into Tanjiro's body, Muzan said that Tanjiro would become the Strongest King among the Demons and that he used the same breaths as that "Monster" (referring to Yoriichi Tsugikuni, the strongest Demon Slayer of all and the only human who defeated Muzan), Muzan believed that Tanjiro would not die by the Sun, due to the fact that Tanjiro was Nezuko Kamado's brother (who, when she was a Demon, became immune in the Sun) and that Tanjiro would make Muzan's dream come true: Destroying all the Demon Slayers, Tanjiro (now Demon King Tanjiro) awakens and regenerates his lost arm and eye, also recovers from Muzan's poison (the poison that was in his eye), soon after Tanjiro attacks one of the kakushi that was nearby, Giyu realizes that Tanjiro has become a Demon and saves the Kakushi that Tanjiro attacks, Tanjiro was about to attack another Kakushi that was nearby but the Sun starts to burn him, Giyu takes the opportunity to call the Demon Slayers who still had the strength to fight and tells them that Tanjiro has become a Demon and says that they have to keep him in the Sun until he dies, so Giyu, crying, attacks Tanjiro and tries to keep him in the Sun until he dies, Giyu begs for Tanjiro to die like a human but something unexpected and terrible happens, Tanjiro becomes immune to the Sun and becomes a perfect creature, Tanjiro attacks Giyu and punches him, but Inosuke Hashibira (one of Tanjiro's closest friends) attacks Tanjiro and tries to talk to him, Inosuke says that the guy with the haori Half-and-Half (Giyu Tomioka) is their friend but Tanjiro doesn't care and attacks Inosuke, Zenitsu (one of Tanjiro's closest friends) can't believe that Tanjiro became a Demon and says that everyone is exhausted and tired, Inosuke doesn't have the courage to attack Tanjiro, Inosuke remembers his moments with his friends Tanjiro and Zenitsu and starts crying stating to himself that he can't attack Tanjiro, before Tanjiro attacks Inosuke, Nezuko Kamado (now Human) enters the front of the attack and holds Tanjiro, Giyu, Inosuke and Zenitsu are surprised by Nezuko's presence and worried by the fact that Tanjiro bit her shoulder, Nezuko crying apologizes for not being able to understand what was happening when she was a Demon and says that Tanjiro always carries everything on his shoulders, Nezuko begs him not to become a Demon and says that they will both go back home, Tanjiro then starts to scream very loudly and dig his claws into Nezuko's back, Zenitsu holds Tanjiro and says that Nezuko is back to being human and if he continues attacking Nezuko she will die, Inosuke punches Tanjiro several times telling him to return to normal and that Tanjiro was not that type of person but a sweet person to others, Tanjiro then uses Muzan's Shockwave Energy Blast technique and knocks down Inosuke, Zenitsu and Giyu but does not knock down Nezuko who continues hugging Tanjiro with all her strength, Tanjiro's appearance changes and now he has tentacles that look like a spine on his back , Tanjiro then attacks his friends and Nezuko continues begging Tanjiro to return to normal, Tanjiro tries to hit Zenitsu but Giyu saves him from the tentacles, Giyu then thinks he must kill Tanjiro before he kills someone but soon realizes that Tanjiro has no weakness (blades red and the Sun cannot affect him), Tanjiro then begins to create an Energy Sphere through his mouth to attack his friends and just as he was about to fire, Nezuko put her hand in front and Tanjiro dodges her attack but still hits Nezuko's arm leaving her badly injured, Giyu realizes that Tanjiro diverted the attack so as not to hit Nezuko and even though Nezuko is bleeding he doesn't attack her, Giyu then deduces that Tanjiro was still alive and was fighting against Muzan's will, in this moment, Kanao Tsuyuri takes a medicine that turns Demons back into Humans (Insect Hashira Shinobu Kocho gave this medicine to Kanao before the War started) and decides to sacrifice her remaining eye using the final form of Flower Breath (which leaves his vision is improved but it slowly blinds whoever uses this technique, Kanao had already used the technique before and lost one of his eyes) to try to apply the medicine to Tanjiro

In the original, Kanao manages to dodge most of Tanjiro's attacks and applies the medicine to Tanjiro's back, Kanao was still hit and falls to the ground, almost blind in both eyes (but was still alive), Tanjiro then stops his attacks, in mind of Tanjiro, Muzan's will tries to convince Tanjiro not to return and to continue being a Demon, since Tanjiro was now a perfect being and would not die in any way, but Tanjiro refuses and says that he would prefer to die as a human, Muzan says that it wasn't fair for Tanjiro to stay alive after everything he did, Tanjiro had attacked his friends and none of them would forgive him for that, besides, many died and it wasn't fair for Tanjiro to continue living, but Tanjiro doesn't believe in Muzan and said that his friends weren't like that, suddenly several arms of those who died appeared to take Tanjiro back, and then Tanjiro is taken back to reality with his Humanity restored and Muzan disappears from his mind finally being defeated forever, Tanjiro (the cure worked and is now human again) later wakes up surrounded by his friends happily welcoming him back

In the Bad Ending, Kanao's eye ends up failing (due to the fact that she used the last Flower Breath Form before) and that's why she is hit and killed by Tanjiro, Kanao falls dead on the ground and the medicine that makes the Demons come back the Human being ends up breaking when he falls, everyone is horrified by that scene, Giyu and Nezuko run towards Tanjiro to try to get him back to normal, until suddenly.....Tanjiro simply stopped moving, in Tanjiro's mind the influence of Muzan tries to convince Tanjiro to stay as a Demon, due to the fact that he did not receive the cure, Tanjiro ends up giving in to Muzan's will and his humanity disappears, Demon King Tanjiro then receives the memories, wills, motivations and desires of Muzan Kibutsuji, Demon King Tanjiro no longer had Humanity and to prove this, he will kill all the Hunters but first he decides to restore his power and to do this, Demon King Tanjiro then gets rid of the Anti-Kibutsuji Drug that was in the blood he received from Muzan ( before the war, Tamayo, a Demon who escaped from Muzan's control had set a trap to weaken Muzan, injecting Muzan's blood with a poison that caused Muzan to age Ten Thousand Years, weaken over time and impede Muzan's escape abilities), After regaining his power, Demon King Tanjiro starts laughing madly and then fulfills Muzan Kibutsuji's dream, Demon King Tanjiro simply kills all the Demon Slayers in a violent and brutal way using his tentacles, leaving only Nezuko alive, Demon King Tanjiro says to his sister that he will be quick and that she will die without feeling pain, Nezuko crying a lot apologizes for not being able to save Tanjiro, Demon King Tanjiro even thinks about transforming Nezuko into a Demon again, but using his "Transparent World" technique Demon King Tanjiro realizes that Nezuko created a resistance and immunity to her demonic Blood (due to the fact that she returned to being human), so Demon King Tanjiro kills Nezuko in a brutal way and thus he turns Muzan Kibutsuji's dream into reality, the Demon Slayers were completely exterminated by the new Demon King and then Demon King Tanjiro starts laughing maniacally at his victory

•Combat Intuition (this trait of Tanjiro was pointed out by Giyu during their first meeting, in which Tanjiro skillfully devised a plan to attack Giyu by surprise, attacking him, not showing the Demon Slayer that he was unarmed, and knocking Giyu down with a hatchet that he had thrown into the air beforehand, the attack failed, but Giyu was still very impressed with Tanjiro's plan, especially considering that he was a rookie at the time, furthermore, Tanjiro also showed proficiency in hand-to-hand combat despite having never practiced martial arts before, allowing him to stand his ground and instantly adapt to Inosuke's animalistic style of unarmed fighting)

•Hard Skull (Tanjiro has an incredibly hard skull, which the Temple Demon likens to a rock, the full power of an attack from his skull caused Inosuke a delayed concussion, while Tanjiro suffered no reaction, Tanjiro also headbutted the Wind Hashira, Sanemi Shinazugawa, having temporarily stunned him, leaving another Hashira impressed with his durability)

•Enhanced sense of smell (Tanjiro has an extremely keen sense of smell, before becoming a Demon Slayer, Tanjiro was known in a village as a boy who had an extremely strong sense of smell, he is able to pick up even the most subtle scents and track his location with frightening accuracy at long distances, it is strong enough for him to smell the "Opening Thread", a slight pause in the enemy's movement that allows him an opening to attack, his sense of smell is so keen that he can perceive what is around you just through smell

•Extrasensory Perception (Through his heightened sense of smell, Tanjiro can perceive things outside the normal range of perception, such as the intentions, feelings and thoughts of other creatures, even animals such as insects and birds, he can also sense the aura and presence of demons and even quickly perceive their strength level through how disgusting and putrid their smell is)

•Master Swordsman (Tanjiro has always shown himself to be a prodigy in sword fighting, with intensive training in the Village of Swordsmen, his skills and dexterity with the blade could match those of the Hashira, the most powerful sword wielders in the entire Demon Slayer Corps, later, Tanjiro managed to match and surpass Akaza, the third strongest member of the Kizuki Twelve and a martial arts prodigy with over a century of experience in hand-to-hand combat, despite not being as skilled as Yoriichi Tsugikuni, he was still able to fight on equal terms with Muzan weakened by the drug Anti-Kibutsuji, showing his immense proficiency with the blade, thus making him one of the strongest swordsmen of the current generation)

•Water Breathing (Taught to him by Sakonji Urokodaki, a former water Hashira and cultivator of water breathing, this was Tanjiro's initial breathing style, he became extremely proficient at it, to the point where he could modify pre-existing forms to suit the circumstances, he also used Water Breathing to face two members of the Twelve Kizuki, namely Rui and Enmu, however, due to his body not being suitable for Water Breathing techniques, Tanjiro decided to switch to the Hinokami Kagura)

•Hinokami Kagura (During his near-death experience in his battle with Rui, Tanjiro awakened this in the memory of his father teaching him this breathing style, as his body was more suited to the Hinokami Kagura, he quickly mastered the Lower Rank demon , however, the strength and fatigue he put into his untrained body caused him to collapse and weaken significantly when using it, through the battle against Hantengu and the Hashira Training, Tanjiro was finally able to master all forms of the Hinokami Kagura, using -him to his full potential against Akaza, when Tanjiro fully witnessed all the forms performed by Yoriichi Tsugikuni in an inherited memory, he realized that his own Hinokami Kagura had unnecessary movements, different wrist angles, footwork and breathing rhythm, removed them allowed him to awaken the legendary Sun Breath)

•Sun Breathing (Upon seeing Yoriichi perform the twelve forms of Sun Breathing through the memories of his ancestor, Tanjiro realized that despite having been replicated with a surprising degree of accuracy for hundreds of years and his own mastery of the Hinokami Kagura, he had unnecessary movements such as different wrist angles, footwork, and breathing rhythm compared to the Sun Breathing performed directly by Yoriichi, removing them allowed him to use the Breathing Style in its purest form, to the point where Muzan Kibutsuji saw Yoriichi's face overlapping Tanjiro's when he was performing the techniques against him

## Sun Breathing

This is the most powerful breath that Tanjiro has, and therefore, it is his main form of combat. This Breath has thirteen powerful techniques:

•FIRST FORM: ENBU (Basically a simple vertical attack)

•SECOND FORM: HEKI-RA NO TEN (Consists of a rotating movement of the body so that the sword covers the user's entire surroundings)

•THIRD FORM: RETSUJITSU KOKYO (It is a double attack moving the sword horizontally. It can also be used to deflect the opponent's attacks)

•FOURTH FORM: GEN'NICHI KOU (It is an escape movement in which, after escaping with several acrobatics, the user leaves a trail made of flames that resembles their own image, which confuses the opponent)

•FIFTH FORM: KASHA (Tanjiro jumps from where he is to dodge an enemy's attack, jumps over the opponent while spinning in the air and, taking advantage of this rotation movement, makes a cut with his sword while releasing flames)

•SIXTH FORM: SHYAKKOTSU EN'YO (A circular sword movement used for defense)

•SEVENTH FORM: YOUKATOTSU (This attack is made with the tip of the sword, in a piercing movement like a spear)

•EIGHTH FORM: HIRIN KAGEROU (In this attack, the sword is covered in flames, but a misty fire, as if it were mixed with smoke, and follows with a much more powerful cutting movement)

•NINTH FORM: SHAYOU TENSHIN (After a jumping movement in the air, Tanjiro makes a horizontal cut with his sword covered in flames, a very powerful blow and perfect for taking off the opponent's head directly)

•TENTH FORM: KIKI ONKOU (Consists of a spiral movement that unleashes a wave of fire and then all this movement is converted into a single attack with the sword)

•ELEVENTH FORM: NICHIUN NO RYU KABURIMAI (One of the most powerful attacks, as it consists of dodging enemy attacks by moving with great speed while forming a large flame dragon, then the user still fires multiple attacks with the sword)

•TWELFTH FORM: ENBU The name is the same as the first form, although in other languages ​​it is translated as Dance of Flames, it is like an evolution of the First Form, only this time it makes two attacks in sequence, one vertical and one horizontal)

•THIRTEENTH FORM (The thirteenth form is, in fact, all the previous twelve forms being performed one after the other, in a cycle, so this thirteenth form is a combo of all the techniques of this Breath, this form was created exclusively to destroy all of Muzan's internal organs)

## Demon King Abilities

•Almost Absolute Regeneration (By assimilating the blood of the Demon King, a being who possesses the fastest and most powerful regenerative power of all demons, Tanjiro's regenerative abilities surpassed those of all other Demons in existence, even Giyu Tomioka noted that this ability, along with his immunity to sunlight, makes him practically invincible to all forms of physical damage)

•Resistance to sunlight (After transforming for the first time, Tanjiro is initially affected by sunlight as any normal demon would be, however, he quickly develops resistance and is soon able to move in broad daylight without taking any damage , it is possible that he is able to do this because, as Muzan noted shortly before his death, Tanjiro is of the same blood as Nezuko Kamado who also overcame his weakness to sunlight as a demon due to his resistance to sunlight, all Nichirin weapons and even Crimson red blades lose their effectiveness, Giyu Tomioka stated that with his immunity to the sun, along with his enhanced regeneration, Tanjiro is practically invincible)

•Biological Absorption (Demon King Tanjiro has the ability to absorb, assimilate, and dissolve organic and inorganic objects)

•Transformative Blood (Demon King Tanjiro's blood has special mutagenic properties that can transform humans into creatures known as Demons, his special blood also appears to give rise to a multitude of Special Abilities to those who receive his blood, such as powerful and rapid regeneration, the power to control flesh, immortality, an accelerated growth rate, enhanced physical dexterity, and even supernatural abilities called Blood Arts/Kekkijutsu)

•Blood Memory Transfer (Demon King Tanjiro can pass his memories and memories to the Demons under his control, just like Muzan Kibutsuji himself did to him)

•Accelerated Development (Instinctively used some of Muzan's blood techniques, and Demon King Tanjiro would eventually regain his reasoning ability (along with Muzan's influence), especially if he satisfied his hunger after devouring a human)

•Biokinesis (As Demon King Tanjiro assimilated Muzan's blood, he subsequently gained his Blood Demon Art, which allows him to control various properties and aspects of his body, Demon King Tanjiro first displays this by projecting whips and appendages shaped like bone on his back, which he uses to extend his attack range, however, due to his savage state, Tanjiro has not demonstrated the same skill in wielding them as Muzan, but after regaining his reasoning ability he becomes better than Muzan, like Muzan, can create any antidote for any type of poison and can alter his physical appearance to look identical to anyone)

•Battle Spirit/Aura (An Overwhelming Aura that causes fear and paralysis in the opponent, making them feel the air becoming heavier and can even cause internal bleeding and external lacerations)

•Short to medium range combatant (With his Blood Demon Art, Tanjiro's fighting style focuses on unleashing attacks at a distance similar to Muzan Kibutsuji, if Demon king Tanjiro had used Solar Breath along with his Blood Demon Art Blood, as Muzan suggests he would, Tanjiro's fighting style would be a combination of melee sword attacks as well as mid-range whip attacks similar to Muzan, Demon King Tanjiro uses this combat style after regaining his ability reasoning)

•Shockwave Energy Blast (Similar to Muzan, Demon King Tanjiro can project a sphere of energy from his mouth that produces shockwaves strong enough to create craters in the ground where it was released, the technique is powerful enough to knock away Zenitsu, Inosuke and Goto as they tried to restrain him, with only Nezuko able to hold him back, even so, Nezuko's arm was damaged to the point where her nails and flesh were destroyed by the blast, Demon King Tanjiro can also use this technique in an extremely high, so he can use the technique at long range like a sphere and up close like a scream, after recovering his reasoning, this technique became incredibly stronger)

•Fatal/Poisonous Blood (Demon King Tanjiro can put a small amount of his blood in attacks, and thus acting as a kind of poison that will slowly kill his enemy, Demon King Tanjiro uses his Blood in demonic body techniques and Solar Breathing)

•Sun Breathing (After recovering his reasoning, Demon King Tanjiro begins to use Solar Breathing with a flesh sword, unlike Kokushibou, Demon King Tanjiro did not focus on creating new forms for his Breathing, but on evolving his power each time and destructive capacity, this Breath became incredibly more powerful and destructive after killing and devouring the Human Race)

## Weaknesses

Demon King Tanjiro does not have any physical or mental weaknesses, but there are two ways to defeat him:

•Complete Destruction of His Body (if Demon King Tanjiro has his body completely disintegrated and destroyed he will not be able to regenerate, if his body is destroyed, Demon King Tanjiro will need three hundred pieces of the flesh of his body to be able to completely Regenerate, but it is almost impossible to destroy it because of its Almost Absolute Regeneration)

•Cure for Demons to turn back into Human (if someone manages to create a cure and apply it to Demon King Tanjiro, he will turn back into Human, but this is almost impossible, because of his extremely resistant skin, Speed, Intelligence and his body control, which can create antidotes for any type of poison or substances)

## Interactions with the BEF

Demon King Tanjiro always tries to fight with strong enemies, and with strong and powerful Bad End Friends, he always tries to fight with Turbo K.O., Genocide Frisk and Dark Danny, which are those that Demon King Tanjiro considers to be incredibly strong and powerful, but the Bad End Friends The one Demon King Tanjiro likes to face most is Bipper and Fleetway Sonic, because they are incredibly powerful, Demon King Tanjiro loves to cause chaos and terror with Darcy, Helos and Bipper, Demon King Tanjiro still tries to become more and more powerful by devouring humans, Demon King Tanjiro doesn't follow anyone's orders, and he will always do what he wants (except kill some Bad End Friend, after all the group is powerful and he loves it)
