Let's go back to that day──.
■Story
The main character, Yoshihide Mizuno, a painter, had gained fame for his beautiful paintings of his sister Misao, who drowned at a young age.
One day, however, he begins to wonder if he is faithfully depicting his sister's drowned body as he saw it. Mizuno begins to question whether she saw her sister's drowned body like this.
In search of the correct memory, Mizuno undergoes ultra-deep hypnotherapy, a treatment that restores memory......
■"Keyhole Peek" system to identify enemies through a keyhole!
It's scary and a bit unreasonable ...... to open a door and have a monster attack you. If you feel that way, we have good news for you. In this game, you can peek through the keyhole into the hallway to see if there are any enemies in front of the door. (I can't guarantee that enemies won't attack you from behind while you are looking through the keyhole, though. Sorry!!)
■ A wide variety of creatures!
Various creatures will appear until the end of the game. There might even be rare creatures? Creatures!
