Yuji Itadori is the main protagonist of the Jujutsu Kaisen series. He is the son of Jin Itadori and Kaori Itadori, and the grandson of Wasuke Itadori.
Yuji was living a normal life in Sendai City until he encountered Megumi and ate one of Sukuna's fingers. After becoming Sukuna's vessel, Yuji began attending Tokyo Jujutsu High alongside Megumi and Nobara as first-year students.
Yuji is a young man of average height and appears to have a slender build when wearing baggy clothing, but actually has a lean and muscular physique.
He also has relatively large light brown eyes and spiky pink hair (brownish blonde in the manga) that's styled in an undercut fashion.
When becoming the vessel for Sukuna after eating his finger, he gains a second pair of eyes that only open when Sukuna controls his body along with his many markings.
Yuji is a fair person who truly cares 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 highly commends "the value of life," and to this end, he will ensure that others receive a "proper death".
Because of this, he believes that it is morally unethical for him to take another human life, and tries to avoid any possibility of doing so unless as a last resort.
He is also not without his more energetic and outgoing traits. Such as his frequent comedic moments where he was seen alongside Nobara gushing about Tokyo and his eagerness to train with Satoru Gojo or even when entertaining both Junpei Yoshino and his mother.
