Breast Goddess, Omune-sama, 春日望

Omune-sama is a classmate of Ouri who was nicknamed "Breast Goddess". In chapter one of the manga, she and other students visited a house that ate men. She got hurt by some corpses there but was saved by Makina. Since then, her fascination with death grew stronger, leading her to stalk both Makina and Ouri. Her attraction towards Ouri also increased, and she wished to become a Shikabane Hime so she could be with him forever. In the anime, Omune-sama was manipulated by Toya because they both believed that death was beautiful. Toya's power transformed her into someone more direct, which eventually led her to kill people at school. Despite Ouri and Makina stopping her, they couldn't save her life. Before dying, she asked Ouri to make her a Shikabane Hime, but her wish went unfulfilled because she didn't meet the requirements.
