Azayahi Shinsei

Azayahi Shinsei is a supporting character in the Jujutsu Kaisen series. He is a third year student at Kyoto Jujutsu High and a semi-special grade jujutsu sorcerer.

## History

Azayahi was born to non sorcerer parents in the metropolitan Kyoto area. He was born a prodigy, excelling in music, sports, studies and pretty much everything he tried to accomplish, he wasn't immediately good at everything but he always put the effort that was necessary to excel and to learn whatever activity he tried or was forced to pick up. He is an extremely quick learner and can quickly comprehend the basics and fundamentals of an activity and continue building knowledge on a particular subject to further excel and surpass the likes of the people around him.

As Azayahi continued to excel, the people around him grew exceedingly envious of him, considering him to be an unnatural and perfect person that had no flaws and who could accomplish anything with ease, they all grew to hate him out of jealousy. One student in particular named " " had tried to approach and become friends with him before, but Azayahi refused since he saw through the person's lies and realized that the smile that he had on his face most of the time was fake and that he usually deceived most people he encountered.

Upon seeing that Azayahi might derange his plans of becoming the perfect student with a perfect reputation, " " started manipulating events and planting the seeds of conflict in people's heads regarding their views and opinions on Azayahi, causing even more negativity to be directed towards him. After the people around him eventually blew up at him for excelling at everything, Azayahi responded back by saying that they had no idea how much he truly tries to do everything and how he is always feeling pressured to succeed in everything, not being allowed to make a single mistake or else everyone would look down on him and criticize his life. Azayahi later found out that it was " " who started spreading those horrible rumors about him which led to Azayahi arguing with him, however, " " first behaved like he did not known anything, and later taunted him in a way that the people around them were not able to hear him confess what he did with joy, this led to Azayahi exploding and beating him up with his bare fists, leaving both " " and his own fists covered in blood, since he had done this in front of the whole school, the rumors about him had now become true, with " " having to be rushed to the hospital because of his injuries. While Azayahi was not expelled because of his status as an honor student, the damage to his reputation had already been done, which led to both his friends and his family cutting ties with him and start acting like he was a dangerous criminal who they should not approach.

In his frustration he started isolating himself from others while continuing to improve, but this time he did so in ways that started to put his health at risk, like skipping meals, sleeping less and having little to no breaks in order to have more time to dedicate himself to everything that he did. A student named " " had been observing him out of curiosity and realized the truth of what had happened and tried to help Azayahi, but he refused out of the newfound fear he had of people, telling him that he shouldn't get near him and to leave him alone, just like everyone else had did, which surprised " " because of how he was the only one able to constantly see through his facade and see the pain that he suffered.

" " was deeply disheartened by what had happened and decided to continue trying to help Azayahi despite his initial refusal. At first Azayahi was incredibly annoyed by this and tried to constantly avoid him and push him away, but he eventually became curious of this strange affair as he could not figure out if he truly had a hidden intention nor could he figure out why he was trying to help him. Deciding to play along, Azayahi started carefully responding back while still being rather secretive about what he truly felt and what he had experienced.

## Jujutsu

### Cursed Energy Manipulation

Black Flash (黒閃 Kokusen): A technique that creates spatial distortion when a user connects with an impact of cursed energy within 0.000001 seconds of a physical hit. The phenomenon causes cursed power to flash black, creating a more potent attack to the power of 2.5 of a normal hit.

Azayahi was not able to perform this technique before, as his control over his cursed energy and cursed technique had always been poor. However, he managed to performed it during his deathmatch with Reido after seeing the cursed spirit defeat both Kiryu and Kokichi, as well as remembering his own past which ended up firing him up so that no one else would be defeated by the cursed spirit. Once he managed to perform this technique for the first time, and after finally gaining a better grasp of jujutsu, he managed to perform it four more times in quick succession, leading to him briefly overpowering Reido.

### Innate Technique

???:

Exploding Purgatory Flames: Azayahi ignites his fist with extremely powerful compressed flames while reinforcing it with a massive amount of cursed energy and channels it into a single attack in which he uses his entire body to create momentum for a punch, which then creates a powerful explosion that resonates inside the target's body, as well as piercing it. This attack was strong enough to severely brutalize Reido, a borderline special grade cursed spirit that boasts the highest durability amongst Mahito's group.

Radiant Sun Palm: Azayahi ignites the palm of his hand with immense firepower and then shoots a small but extremely powerful ball of flames that creates a bright explosion that covers a large area with a flaming pattern that resembles the shape of the Sun.

Hope Shattering Arrow: Azayahi ignites his fist with his flames and then shapes it into an arrow, he then draws the arrow back using only his middle and index finger and releases it, shooting out a projectile that causes a powerful explosion upon contact. Azayahi replicated this technique after he saw Sukuna use it against Mahoraga, naming it after the despair that he felt upon seeing Sukuna possess such a technique that surpassed the power of both him and Jogo's. He used it to great effect during his battle against Uraume and Pseudo-Geto, catching Uraume off guard with the explosion as well as contributing to the destruction of Pseudo-Geto's Uzumaki technique.

### Barrier Techniques

Simple Domain: An anti-domain technique that erects a small barrier around the user to protect them from the effects of a Domain Expansion. Azayahi first used this to try to protect himself from Megumi's Chimera Shadow Garden during the individual battles of the Kyoto Sister-School Goodwill Event (2017), but as Megumi's domain expansion was not yet completed as it only enhanced his cursed techniques, the anti-domain technique had no effect on it, which led to Azayahi being caught off guard, allowing Megumi to briefly gain the edge over him. He was later shown using it during the Shibuya Incident Arc to protect himself from the auto-hit provided by Sukuna's Malevolent Shrine, where Azayahi noted that he would have been slaughtered if he had not used this technique.
