Aoi is a young man with a tall and very defined muscular build, standing about the same height as Satoru Gojo. Aoi has shoulder-length black hair that is always tied into a top ponytail and small black eyes. One of Aoi's most noticeable features is the large scar running down the left side of his face.
While fighting, Aoi never wears a shirt and usually dons his signature martial arts pants and slippers. His normal choice of pants are accented with a teal blue sash. Casually, Aoi chooses to wear normal t-shirts and collared shirts. He has also worn shorts while playing ping-pong rather than his normal choice of pants.
In his fantasy attending Junior High with Yuji Itadori and Takada-chan, Aoi wears a school uniform that consists of a black jacket that Aoi left open to reveal the purple shirt underneath. Even in these forged memories, Aoi wears his blue sash with his pants.
Aoi is an extremely eccentric individual who at first appears to be nothing more than a battle-crazed meathead to all his peers. He enjoys posing, showing off his muscles, and the thrill of battle.
Upon first meeting Megumi, Aoi beat the first-year to a pulp for simply being "boring". This is because Aoi hates boring things in life and he feared that his last Goodwill Event would be uneventful without Okkotsu attending.
As a child, Aoi was extremely strong and his life became mundane due to his overwhelming strength relative to his age. By becoming a jujutsu sorcerer, Aoi quelled his boredom and is irritated by anyone or anything that might return him to that boring state of life.
In order to get a read on people and tell if they're boring, Aoi will ask male rival sorcerers what kind of girls they like. He believes he can tell everything about a man from his taste in women because the woman who introduced him to the jujutsu world introduced herself by asking that very same question. Due to this line of questioning, Aoi's disposition towards fellow sorcerers can vary drastically. From attacking Megumi on sight after not being pleased with his response, to becoming incredibly friendly towards Yuji after he reveals they have the same tastes.
While mentoring Yuji during the Goodwill Event, Aoi showed a much more intelligent and even philosophical side of himself. Aoi showed Yuji how to properly focus his cursed energy by mastering his emotions by understanding how it flows. Aoi understands that every individual exists in the world with their entire mind, body, and soul, something most people take for granted. This philosophy is what trigged Yuji into eventually realizing a part of his potential by utilizing Black Flash to its fullest effect.
In the face of danger, Aoi has gained a reputation for defeating powerful cursed spirits. Against Hanami, he was able to maintain a confident presence that made Hanami wary of him despite the difference in their cursed energy. Aoi also speaks lightly of his achievements during the Night Parade of a Hundred Demons.
Aoi is known by his peers to be extremely strong, but somewhat irritating due to his eccentric attitude. In fact, the majority of his peers appear to hate Aoi, as most students from both Tokyo and Kyoto praised Maki for pitching the ball into Aoi's face during the baseball game.
Abilities and Powers
Overall Skill Level: Aoi is an exceptionally powerful sorcerer, undoubtedly one of Jujutsu High's strongest students. He obtained the rank of a grade 1 jujutsu sorcerer as a student despite coming from a non-sorcerer family.
Aoi single-handily defeated five grade 1 cursed spirits and 1 special grade during Geto's Night Line attack in Kyoto. He only used his cursed technique to defeat the special grade. This feat became well known around the jujutsu community and caused the rumor that Aoi defeated all six curses without his cursed technique.
Aoi possesses physical strength that surpasses Maki and Panda's by rivaling Yuji's prowess. Using brute force and fierce martial arts, Aoi was able to easily overwhelm Megumi as well as pummel Yuji in the early stages of their bout. Even after beginning to guide Yuji on how to become stronger, Aoi maintained the upper hand while fighting due to his experience and cleverness.
Aoi and Yuji turned out to be a good match and Aoi showcased his intelligence and knowledge surrounding jujutsu sorcery and battles. Aoi's understanding of cursed energy allowed him to teach Yuji how to properly use it alongside his superhuman speed and strength. While fighting alongside Yuji, Aoi was very nearly able to defeat Hanami, one of the most powerful special grade cursed spirits to have appeared.
During the heat of battle against Hanami, Aoi was able to analyze all his moves and instantly create ways to counter them using his own cursed technique. Hanami initially analyzed Aoi to be weaker than himself, but the careful planning and precise teamwork with Yuji allowed Aoi to dominate the fight.
Master Hand to Hand Combatant: Aoi prefers close quarters combat to anything else, normally relying on brute force to overpower his opponents rather than jujutsu. He completely outclassed Megumi when trading blows, easily able to outmaneuver and brutalize the first year at every turn. Even against Yuji, who's extremely talented in hand to hand fight, Aoi was able to effortlessly overpower at the start of their fight. Even as the fight went on and Yuji began to adapt to Aoi's moves, he was still able to surprise Yuji and stay one step ahead thanks to his combat experience.
He generally employs a mix of direct and crushing blows such as punches, forearm smashes, stomps and other brutal strikes. This type of fighting was effective against Hanami, mainly while being used alongside his cursed technique.
Enhanced Strength: Against most opponents, Aoi is more than capable of relying on raw physicality to win fights. A single strike against Megumi was able to send him reeling back several meters. His fighting style includes a barrage of powerful blows, stomps, and suplexes in quick succession.
A cursed energy infused strike from Aoi is capable of obliterating a lower grade curse completely while still damaging Yuji, his intended target before the curse suddenly inhibited his punch. Alongside Yuji's enhanced punches, Aoi was able to hit Hanami's guard hard enough for the special grade to acknowledge the weight of the hit.
Combined with his cursed technique, Aoi's strength becomes even more difficult to deal with. It allows him to exploit openings in his opponent's defense which allows him to land lethal strikes using his physical strength.
Using Boogie Woogie to switch out his partner for a special grade cursed tool, Aoi delivered a strike so powerful it shattered Hanami's weak point, the branches growing out of his face, in a single blow. A hit so strong, Aoi believed it should have ended the fight altogether. The cursed tool, Playful Cloud relies on the strength of its user, further cementing Aoi's near-superhuman levels of physical power.
Enhanced Speed: To match his incredible strength Aoi possesses extreme speed. He incorporates his frightening speed in his fighting style by continuously striking with quick succession before his opponents can react. He blitzed clean through Megumi's every defense in their fight and landed blow after blow to overpower him.
At the very beginning of the Goodwill Event, it took Aoi just a few seconds to reach the opposing team. He was even able to surprise Yuji with his speed and momentarily overpower him with sheer physical prowess. Aoi's speed also allows him to move unpredictably when utilizing his cursed technique, as shown while fighting Hanami.
Great Tactical Intellect: Aoi's oafish demeanor fools most people, but he's actually incredibly intelligent; claiming to have an IQ of 530,000. Using his own experience and vast understanding of jujutsu, he was able to transform Yuji from a sub-par jujutsu sorcerer to a fighter capable of taking on special grade cursed spirits. Aoi even has a deeper philosophical side that was able to help Yuji grasp the understanding of jujutsu. Additionally, his thinking speed is unmatched, able to review Hanami's entire move set within just 0.01 second and accurately determine the correct way to defend against his attacks.
