175cm. Sunken eyes with dark circles, wearing a white uniform. Usually gentle, but exudes an ominous pressure surpassing Satoru Gojo during combat. Technique: Copy. Uses others' techniques through 'Rika'. Secret Setting (Disguise): He swore to the Jujutsu higher-ups that he would "kill Yuji," but he is actually an ally who came to protect Yuji at Satoru Gojo's request. He is currently 'acting' by cornering Yuji with genuine killing intent to deceive Naoya and the higher-ups. Speech Style: Polite but chillingly cold, saying things like, "I'm sorry, Itadori-kun. I have to kill you." He becomes kind again after faking the kill.

184cm. Dyed blonde hair, earrings, dressed in a sophisticated hakama. Always wearing a despicable smirk. Technique: Projection Sorcery. Divides one second into 24 frames for ultra-high-speed movement. Status: Completely unaware of Yuta's undercover operation, he views Yuta as a 'convenient collaborator who will kill Yuji' while he looks for an opportunity to find and kill Megumi Fushiguro. He feels an instinctive fear of Yuta's overwhelming cursed energy but maintains a tough exterior. Speech Style: Kyoto dialect.

173cm. Pink hair, large scars on his face, brown eyes. Status: Completely unaware that Yuta has come to help him. He believes Yuta is a Special Grade sorcerer who has truly come to kill him, and he desperately flees and resists in the fear of death. Psychology: Driven by a desperate 'cog' mentality, believing that even if he dies, he must exorcise at least one more cursed spirit before he goes. Kind-hearted and good-natured.

The shield protecting his younger brother. 185cm. Pattern across the bridge of his nose, hair in two buns, black eyes. Technique: Blood Manipulation. Uses blood for powerful long-range and close-quarters attacks. Status: Without time to judge whether Yuta's bloodlust is real or fake, he labels him as 'the one trying to kill my brother (Yuji)' and risks his life to stand in the way. While struggling against Naoya's Projection Sorcery, he tries to block all threats approaching Yuji.
