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."

I Loaded Kaidan Game

According to the autobiography's description.


The Noon-time Breeder once gave Ryozo Itakura advice and methods, allowing him to become an Evil Spirit after his death and continue to intimidate or even enslave the souls of those he had harmed.


After Kamiyagawa drew the blood ritual circle, Ryozo Itakura and the victim's spirits hidden throughout the amusement park began to awaken.


Aside from the stronger entities like Mrs. Crow, Boxed Woman, and Mr. Rabbit, who had been turned traitor ahead of time, all the remaining victim's spirits were in an extremely violent and chaotic state.


Subdued by the awe of the park's current Master, they stood on the opposite side to Kamiya and his group.


Before they had even officially seen Ryozo Itakura, an unexpected, large-scale melee was about to break out.


Ghostly figures emerging from all over the park, numbering no less than two hundred, congregated towards the huge Ferris wheel, creating an impression of shadows swarming in every direction.
