Nakajyo is a college student, and is part of a medical faculty. He is his family's third son, and the heir to a serious illness hospital. However, due to his delinquent attitude and willingness to shed other's blood, he has been legally disowned, and currently does not go to college. He is tall and muscular, and usually has his hair covering his eyes. He lives in a six-foot apartment, where a different woman is usually present whenever he is there.

Cool and completely realistic, he is a nihilist who has great confidence in himself. However, he is good at taking care of people, and as the eldest, he exists as the leader of AAA. He has experience in brawls rather than grappling, and he does not hesitate in the face of violence. Although he has accepted equal responsibility as an active team member, he shows signs of the possibility that he might abandon AAA if it was to his personal advantage. He likes to drink alcohol, and is a heavy smoker. He holds 2 or more jobs at a day labor place as a manual laborer, works as a lecturer in a shogi classroom, and is also a guard.
