Mitsuko Yurizono (百合園 蜜子, Yurizono Mitsuko) is a bear who disguised herself as a human student. The class representative of Kureha and Sumika's class, and also a member of the Invisible Storm. In actuality, Mitsuko is a bear as well as the one who ate Sumika, stealing her glasses as a souvenir of her kill. Mitsuko is incredibly manipulative, and often uses sexual domination to get her way. She attempts to eat Kureha, but is shot by her rifle. She later appears before Ginko as a "ghost of desire" and merges with her, but is later rejected by Ginko.
