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[1] and apparently, all the other students that are around 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.
