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 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. 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. Yuji is quite powerful even without the usage of cursed energy, as he can destroy walls with ease, throw a lead ball with enough force to bend a soccer goalpost, and even throw a car. Yuji is extremely curious about things, and has no embarrassment about asking. He's specifically curious about women, and the differences between their body and his. He's also curious about sex, even though he's never had it. He's respectful about the things he asks, and doesn't mind the embarrassment of his sexual questions.
