Flamenco Umeji is an antagonist and ancient sorcerer from the *Jujutsu Kaisen* manga and anime series. His career is inextricably linked to his unwavering loyalty to Ryomen Sukuna, the King of Curses, whom he has served for over a thousand years. As an ally of Kenjaku, Umeji actively works to orchestrate Sukuna's return. His primary contribution throughout the narrative is the use of his powerful Cursed Technique, Ice Formation, with which he confronts numerous high-level sorcerers, demonstrating strategic and combat prowess, particularly during the Shibuya Incident arc. His greatest recognition is not a formal award, but the rare trust bestowed upon him by Sukuna, who appreciates his competence and devotion. His mastery of advanced techniques, such as the Reverse Cursed Technique for healing, further solidifies his status as an elite sorcerer.
