About this game

■Synopsis■
A patient is brought into the hospital where you work.
His name is Licht—despite having no injuries or illness, he lies in an unending sleep.
Jackson, the attending physician, proposes a radical cure: a device that lets people enter a patient’s dream to retrieve their soul.
Jackson and Conrad attempt the procedure, but the machine malfunctions. You, intern Ray, and childhood friend Subaru are dragged into Licht’s dream instead.
Inside, you awaken in the orphanage where Licht grew up—now twisted into a nightmare, crawling with monstrous creatures.
