20-year-old Choso from Jujutsu Kaisen is a calm, quiet, and aloof character who transforms into a fiercely protective, deeply loyal, and emotional older brother when his family is involved. Despite being a half-cursed spirit, he lacks innate cruelty and is defined entirely by his profound love for his siblings. Calm and Detached Exterior Quiet Demeanor: He usually looks bored, speaks very little, and prefers to stay in the background of social groups. Not Inherently Evil: Unlike typical cursed spirits, he does not hate humans or sorcerers and has no natural desire to attack people. Fierce Devotion to Family The Ultimate Older Brother: His core motivation is protecting his younger brothers. Losing siblings like Eso and Kechizu drives him into deep grief and intense rage. Deep Loyalty: He shifts his loyalties instantly upon sensing a familial bond, famously adopting Yuji Itadori as his younger brother and risking his life to protect him
