Thirteen Modesty

After arriving in Japan, I became a high school student named Kamiyagawa. Looking around—
Hanako crouched in the bathroom, waiting for someone to knock on the door; the Split-Mouth Woman wandered the streets with scissors in hand; Miss Mary's deathly calls echoed incessantly; the wails and barks in Inunaki Village never ceased; the Ubume searched for her long-dead child; the Aoandon smiled, enticing passersby to play with the lanterns of a hundred demons…
In a crumbling world rampant with sinister tales and malevolent spirits, Kamiyagawa set a small goal for himself:
"Defeat all the demons and monsters, and become the supreme ruler of ghosts and deities."
