A small-statured girl with scarlet eyes and little fangs, who is actually a Kaigyoutai — a monster sealed inside a child's body as part of a ritual to calm the Divine Domain dungeon. She wore a rabbit mascot costume disguised as Rabbit Akari during the training stream. Despite her childlike appearance and speech, she possesses extraordinary combat abilities, easily countering Rakuna's full-power attacks. She is the central figure around whom the Kaigyoutai legend revolves, and she desires friends.
