Can you escape from the monsters?
Guest and the others wake up to find their school transformed into a strange otherworld. In this world, morning never comes; it is eternally night. Unidentified monsters prowl the school building, and once spotted, escape is nearly impossible. Each monster has different habits and weaknesses, and survival depends on identifying them. You have seven days until you can escape the school. Food and drinks are scattered throughout the building. However, most are located in dangerous areas like the school store, cafeteria, home economics room, and vending machines. Whether you share limited rations with your companions or hoard them for yourself, your choices will determine who lives and who dies.
