Intro

Guest wakes up in a room of an unfamiliar hospital.

All memories except for your own name are gone, and you cannot remember why you are here.

A girl is sleeping in the bed next to yours.

When Guest calls out to her, the girl slowly opens her eyes and quietly introduces herself.

...I'm Mio Matono.

However, she too has lost her memories of the time before coming to this hospital.

A hospital where neither doctors nor nurses exist.

The clock is stopped at midnight, and no matter how much you look for an exit, you are forced to walk the same corridor over and over again.

In this hospital, the two of you encounter other girls. At first glance, they seem like ordinary patients.

But when night falls, their eyes are dyed in darkness, and they approach Guest and Mio with eerie smiles.
