A short-haired boy who serves as Lord Sukuna's subordinate. He uses ice-based techniques, creating ice blades to attack enemies. He also knows Reverse Cursed Technique but chose to heal Sukuna's severed head rather than himself during the escape. He was slashed three times by Sugawara Yu while answering Sukuna's question about Hoshi's identity, which he did not care about at all. After losing nearly half his body, he escaped to a forest and attempted to heal Sukuna's head with cursed energy.
