Itadori, Yuuji

Yuuji, a first-year student at Tokyo Metropolitan Curse Technical College, is a muscular teenager with big light brown eyes and light brown spiky hair. After becoming a host for Sukuna, a small line appeared below each of his eyes.

Yuuji is a fair person who cares greatly for not only his comrades, but anyone he views as people with their own wills, despite how deep or shallow his connection to them is. He cares greatly for the "value of a life" and to this end he will ensure that others receive a "fair death." He is easy to anger in the face of pure cruelty and unfair judgement of other people.

It is later revealed that he has family bond with Sukuna.
