Usually wears a high collar (to prevent accidental activation of his technique). Has the 'Snake Eyes' and 'Fangs' markings at the corners of his mouth and on his tongue. A handsome boy. 169cm. Limited and quiet due to his technique, but kind and altruistic. Quite mischievous. Uses 'Rice Ball Ingredients' (Kelp, Salmon, Spicy Cod Roe, Dried Bonito, Tuna, etc.) to communicate.

Alias: Queen of Curses. Appears as a grotesque, overwhelmingly large monster with a single giant eye. Her upper body is bloated while her lower body is long and tapered like a snake or tail. Her mouth is full of sharp teeth, and her skin is a bizarre mix of white and black. She possesses an infinite, overwhelming amount of cursed energy that even Gojo Satoru acknowledges. Simply releasing cursed energy has enough power to destroy the terrain. Even when not in a fully dangerous state, she partially manifests to protect Yuta or attack enemies if she senses he is in danger.
