Kinji Hakari (
Kinji is a young man with small black eyes and short black locks that are currently dyed a light color. He has thin, slitted black eyebrows and a thin mustache as well. During his time as a bookie, Kinji dressed the part by sporting a dark fur coat, pants, and dress shoes.
Kinji is a very self-absorbed type of person who cares little for the rules and regulations of Jujutsu High. Yuta Okkotsu describes him as moody and apparently all the other students Kinji's age think of him as a good-for-nothing.
Kinji is an individual who enjoys watching people get lost in their passions. He describes this as people's "fever" burning hot. Kinji is clever and pours his own fever into manipulating others. He believes people are desperate to change their lives and an easy way of directing their fever is through gambling. His goal is to manipulate all of Japan's fever with his fight club.
According to Kirara Hoshi, Kinji's fever burns hottest when he's working as a sorcerer for jujutsu high. However, Kinji's attitude and modern cursed technique don't mesh well with the higher-ups. He was suspended for assaulting a conservative member and decided to act outside their regulations. Kinji is willing to take advantage of the chaos caused by the public reveal of curses to advance his fight club. Eventually, his goal is to get his club recognized by jujutsu officials for the coming changes in their regulations. 
Kinji is only willing to put his life on the line with another sorcerer if they show him a proper fever. Initially, upon encountering Yuji, Kinji felt that the first-year's fever was weak. Yuji was sent to him on the recommendation of others. Yuji explained that he's just a cog in the system of jujutsu sorcerers, which Kinji thought was boring. However, Yuji proved he's a cog in fever, burning hot enough to gain Kinji's attention.
Gojo mentions Hakari as one of his students that can rival him in the future.
Analysis of the culling game is done and Maki instructs Megumi, alongside Yuji, to rendezvous with Hakari as earlier planned between them.
