The Playwrights

Kabenashi Tsubasa didn't feel like anything was wrong with his life and he was living normally until he came across a mysterious girl named Kurayami Akari.

She asked him to help her with her search for the "door." As he found himself learning things that he shouldn't have, he was forced to confront things that he wished he had never seen or known existed.

"Do you doubt your existence?" Kurayami asked him.

Tsubasa was confused and didn't understand what Kurayami meant. He wondered what ignorance truly was, and whether it was a bliss or a sin.
