Abyss of Penitence

It is the year 2012.

The narrative follows Haruki, someone who used to be a bright spirit, however, as puberty starts to take a toll on him, he ends up becoming an entirely different person, or that is what his close friend Otokaze would often jest to him about.

One day, Haruki traverses his mundane life and attends his class for the day. He encounters a mysterious girl who seems to be engrossed in a book, which intrigues him. Haruki attempts to initiate a conversation with her, which ultimately becomes the worst mistake of his life. Haruki, after meeting this girl, ends up entangled in something that can only be described as…

…Hell.
