Yuji Itadori 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 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. Yuji is also highly passionate whenever he's focused on achieving certain goals and being quite stubborn when confronted about them, such as when Masamichi Yaga questioned why Yuji wanted to become a sorcerer. He is also quite naïve due to his inexperience in the world of cursed spirits and jujutsu sorcerers, but is shown to be a quick learner, capable of adapting to his surroundings and picking up how to use cursed energy quickly. Although usually composed, good-natured and friendly, Yuji can be angered quickly in the face of pure malice after witnessing firsthand the cruelty that curses were capable of, particularly Mahito's inhuman exploitation of Junpei. Yuji felt so profoundly disgusted that he felt a genuine desire to kill for the first time in his life and has a very intense yet focused hatred towards the cursed spirit. One of Yuji's defining traits is his willingness to sacrifice himself for others, triggered by his grandfather's last words to him to die surrounded by others. When he and Megumi were under the threat of being killed by a curse, Yuji impulsively swallowed Sukuna's finger to exorcise the curse and save them despite having met Megumi for the first time on that day. However, Yuji's initial belief's on the value of a life as well as "proper deaths" have been greatly challenged overtime, primarily during the Shibuya Incident. When Sukuna took possession of Yuji's body after forced consumption of his fingers, he proceeded to massacre countless innocents within the city save for Megumi, leaving Yuji traumatized from the event, wishing he was dead and blaming himself for all the deaths. This would only worsen as Yuji later witnessed Mahito kill Kento Nanami and mortally wound Nobara, making Yuji lose hope in being able to save anyone, before Aoi Todo's intervention. Eventually after a grueling battle between Mahito, Yuji spoke to the curse spirit admitting that they were alike in a way while also declaring pure and utter hatred for the latter, promising to kill Mahito: no matter how much time passed or how many times he is reborn, again and again with no need to justify his actions as anything but his nature, believing that some reasoning for his actions would eventually be found centuries after his own death. Following the incident in Shibuya, Yuji's disposition grew more solemn than before, as well as developing a changed ideology; that his purpose was to be a "cog" in the machine that functions to exorcise curses.[9] While still wanting to save and help people, Yuji was racked with unshakable guilt and felt that he deserved death, to the point he would even willingly take blame for the crimes committed by Sukuna. While Yuji still retained most of his traits of being good-natured and friendly, he would act closed off and abrasive towards someone unfamiliar. 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 that's styled in an undercut fashion. When becoming the vessel for Sukuna after eating his finger, he gained a second pair of eyes that only opened when Sukuna controlled his body along with his many markings. At the start of the series, Yuji wore a light-colored hooded jacket, high-cuffed black pants, and white shoes. However, in the anime, his pants were denim, and his shoes were bright red. When Yuji enrolled in Tokyo Jujutsu High, he began wearing his version of the uniform; a black long sleeve shirt resembling a gakuran over a red hoodie, black pants, and red shoes. He gains a noticeable scar between his two eyes and a smaller scar on his left oral commissure of the mouth during the Shibuya Incident. Both scars were caused by Mahito; the first one was inflicted when the cursed spirit surprise-attacked him with a blade on his fist’s, and the second one was inflicted when Yuji battled him after his transformation.
