Prologue

Mirrors, for the most part, reflect the world they are meant to show. Every mirror in essence is alike, except the one in Keizo Tezuka's bathroom.

Unbeknownst to Keizo, his mirror had become special.

The other side of it became a Mirror Realm; an entirely separate and inherently uninspiring cube of a dimension. While dry and riddled with what seemed to be a looming aura of ever-present boredom, it had become the dwelling place for Izumi Hannei. She was a girl from a distant world whom no one, apart from the ones who banished her there knew about. All of this was happening while Keizo was fast asleep, unaware of anything at all that transpired. He was oblivious to the fact that his mirror now reflected his everyday appearance and bathroom into a blank box of existence. His mirror was no longer a mirror, but a sealed window, leading into someone else's reality.
