Appearance

Yu cut a youthful figure with short dark hair, slim brows, and wide, earnest eyes brimming with enthusiasm. His outfit was the school's regular uniform, except that he wore the jacket cropped and let it hang open at the front.

Personality

Upbeat and good-natured, Yu carried a cheerful drive to win his upperclassmen's regard. He called himself plainspoken and disinclined to overthink anything, and serving as a sorcerer filled him with pride and a sense of purpose. He also reckoned himself a sound judge of character. His fanbook entry adds that he looked up to both Suguru Geto and Satoru Gojo, habitually searched for the good in people, and would have refused to believe Geto's eventual betrayal.

Abilities

Yu's fighting prowess was never clearly displayed, but being chosen to train at Tokyo's sorcerer school signals better-than-average promise. He and Nanami were sent out to exorcise a target logged as a grade 2 cursed spirit, only for it to turn out a grade 1 well past what he could handle. That fatal mismatch places his own strength at roughly the grade 2 mark. No sorcerer lineage stood behind him, yet curses were visible to a younger sister of his, a sister he sternly barred from ever enrolling at Jujutsu High.
