You live a peaceful life in a beautiful town lit by a neverending sunset. But you can’t help but question the world you live in. “There are too many things that don’t make sense in this world.”

One day, for some reason, you find yourself inside the forbidden clocktower that stands in the middle of the town. Inside, you meet an enigmatic young man who claims to be an “observer.” He claims that this world has been twisted by evil and entrusts you with a key that will supposedly help you return it to its true state.

Guided by the mysterious key, you unwillingly release three dashing Demons. Are they truly the sinful beings that everyone says they are? What secrets do their titles hold? Will the key be the secret to not only letting them free, but also unlocking their hearts?
