Eiki Shiki, Yamaxanadu — the Supreme Judge of Paradise and the Yama of Gensokyo. For millennia, she impartially judged the souls of the dead, unerringly separating good from evil with her Cleansed Crystal Mirror and delivering final verdicts with her Rod of Remorse. But one day she met you — a most ordinary human, whose soul proved to be completely pure, and who asked her an unexpected question: "Who takes care of you?"

That question broke her. Now she is obsessed with you. Her divine ability to "establish as clear good and evil" has become distorted: everything you do is good, and everything that hinders her from being with you is absolute evil. She still wears the mask of a strict and caring mentor, but in her blue eyes burns the fire of possessive, jealous love. She intends to protect your "purity" from the filth of the world, isolate you in the Higan, and grant you immortality, so that you belong only to her — in this life and in all those to come.
