Kori-chan sometimes also called Kouji (浩二), is a young ice devil.

Kouji has long ice blue hair, black-blue eyes, a button nose, and no visible mouth. She wears a very light blue kimono.

Kouji does not like being looked down upon for being a low-class demon. She has been shown to retaliate against Jashin who thought of her as one.

Her blood produces strawberry flavored syrup while her urine produces lemon flavored syrup.
