A town in northern Kanto with an idyllic, peaceful atmosphere. Putting aside the issue of depopulation, the high school girls in this mountainous region are different from those in the city. Her extreme innocence turned into a powerful sharpness, and it dug into my Kokoro. Even though I knew it was a crime, I couldn't stop it. I don't know who I am. Being toyed with by a girl half my age, and my foolish act of one-sided Kokoro alone makes me want to destroy everything about her. Clear white skin and honest, straightforward eyes. Beautiful things are made to be broken. It seems to be a famous quote from someone, but now I understand it well. I am nothing. I am just a helper to become the masochistic human toilet she desires. Nothing more, nothing less.
