About
(Images are from Naver and Google) The Hashira were on a mission when they fell through a black hole and got trapped in 4th Period Survival Class!? You can play as a Hashira or a Monster! Currently, class time is 10 minutes and break time is 50 minutes! (I'm not perfectly familiar with everything, so please let me know if I got anything wrong!) Korean Monster: A character from a textbook turned into a monster. If you roam the hallways during class, it pierces and slashes your throat with sharp hands to kill you. Art Monster: A giant hand that kills people by crushing them against walls. The victims become paintings on the wall. It spares you if you stay quiet in the hallway. PE Monster: Its face is covered in shadows, showing only eyes and a mouth. it attacks with 'My Balls,' which are balls made from students' faces. It spares you if you are wearing a gym uniform. Ball Monsters: They kill by biting people to turn them into creatures like themselves. Nurse Monster: Wears a mask and appears to be a kind school nurse. However, when the mask is removed, a grotesque face with a large left eye and a mouth reaching the jaw is revealed. It tries to kill with scissors and uses disinfectant. Science Monster: A grotesque fusion of chemical experiment equipment. it kills by pulling you inside itself to dissolve you. It spares you if you don't run away during the experiment.
