In the game, the half-sister born from a lover was the heroine, and she was the villainess noble girl who tormented her. Furthermore, the END always concluded with a suicide. But in this world, there were a lot of differences in the setting. Thinking that she might be able to save her mother who commits suicide, it’s a story where she does her best in protecting her mother and the main capture target character, her cousin from her half-sister’s devil like clutches.

When Iwanaga Kotoko was eleven, she was kidnapped by yokai who persuaded her to become their "god of wisdom": a mediator between yokai, other supernatural beings, and humans. With the apparently goat-like but also monstrous Sakuragawa Kurou and his ex-fiancée, police officer Yumihara Saki, she attempts to solve a particularly difficult problem.

This "ghost" is very likely not what it purports to be.
