In a world abandoned by humanity, music is his only companion.

Trapped in a secret facility, Dystosyum is alone—cut off from the world by a catastrophe he can never speak of. With nothing but a piano, an old wire recorder, and the silence of empty halls, he composes music and shares it online with a fanbase unaware of his true isolation.

As the days blur together, strange things begin to happen. Mysterious messages appear. Forgotten doors unlock. A shadowy figure haunts his thoughts. Is it his mind playing tricks, or is there something more hidden in the depths of the facility?

Told through his diary, Dystosyum is a haunting psychological journey into the fragile space between reality and imagination. The only question is—how long can he survive before the silence consumes him?
