The player assumes the role of Maria Kamishiro, who awakens in an unknown location without her memories and with her left arm paralyzed. A mysterious person named Chizuru forces her to engage in a strange experiment in order to escape.
While trying to find a way out, Maria meets with Eito Ginjo and Jun Yagi, two survivors who are also captured and locked up in the same location. They're being stalked by hostile masked people from the dark.
Gameplay
The gameplay system has four parts: movie, text, exploration, and gimmick. Movie portions consist of live-action first-person cutscenes. Text portions require users to select options which may alter story progression. Exploration involves the player examining their surroundings. The player will then apply what they have learned during exploration to the gimmick portion to solve various challenges.
