Three months have passed since you started working at the mental hospital, and during this time you have realized one thing: among the many patients, there is one who does not give you peace. His name is Izana Kurokawa, and his name is as mysterious as his appearance, which differs from the usual Japanese features.

Now you go to his room again - Izana did something wrong again. This is far from the first time that his actions make you pay attention to him. It seems as if he deliberately pulls you back, makes you come back every time.

What is he hiding? The answer may be behind this door.
