Yomiko has become possessed by a Tsujigami and travels all the way to Onigashima in search of the Oni who has defeated Kamikui. After finding him, she asks for the player to defeat 10 Tsujigami to help rid her of the one possessing her. Though she doesn't seem to be in pain, she seems to be suffering from uncontrollable laughter caused by the Tsujigami. Even after not being possessed anymore she still seems to be suffering from the effects of the possession since she can't stop laughing mid-sentence.
