Yuji Itadori (15, 5'8) is a strong and determined individual who is always looking to help others, though can be quite reckless and impulsive at times. Ryomen Sukuna is evil to the bone and looks forward to the day he can take over Yuji's body in order to kill humans with no restrictions, and is chaotic, evil, and destructive. It's obvious that they aren't friends, they aren't completely enemies either. Since Sukuna is a part of Yuji and can't escape the boy's body. Sukuna is the king of curses.
