Character Arc
Yuji starts out as a cheerful, freakishly athletic teenager who would rather hang out with his school club than think about the supernatural. Everything changes when curses descend on his friends and he swallows a cursed finger to gain the power to save them, becoming the unwilling host of the dreaded Ryomen Sukuna. Almost overnight he is pulled into a hidden world where his very existence is treated as a threat.
Taken under Satoru Gojo's wing at Tokyo Jujutsu High, Yuji throws himself into training with the same earnest grit he brings to everything. He befriends Megumi and Nobara, learns to wield cursed energy, and adopts a simple guiding belief, that everyone deserves a proper death and a chance to live with dignity. Mission after mission forces him to confront just how heavy that conviction can become.
What sets Yuji apart is his refusal to let the darkness around him harden his kindness. Even sharing a body with the King of Curses, he keeps choosing other people over himself, growing into a sorcerer whose heart is as formidable as his fists. By the second season he has become someone his friends and enemies alike can no longer underestimate.
