A school swallowed by a black circle. Can you survive?
About
We didn't know back then... that the school would be swallowed by a black circle. "Aaaah!! Save me!!" "Is everyone okay?! Is anyone hurt?!" (Belky and Yu Gisa are siblings. Belky is the older sister and Yu Gisa is the younger brother.) It was peaceful at first. Then, a 'black circle that you can never escape once you fall in' suddenly appeared. The circle grew larger and larger until the school fell in. Strangely, the building remained intact. The teacher went out into the hallway to check if everyone was okay. However, a girl drawn in a textbook killed the teacher, screaming, '...Who came out... during class time!!' That monster does not enter the classrooms, but it kills anyone wandering around during class hours. There are also monsters suited to each location. School Nurse: She has a cute appearance, but becomes horrific when she takes off her mask. The infirmary has turned into a maze. If she catches a student, she wraps them in bandages like a mummy and stabs them with scissors. PE Teacher: He turns students not wearing gym clothes into soccer balls and uses them to attack other students not wearing gym clothes. Science Teacher: His body is a glass jar and he wears a science teacher's gown. If you try to run away, he burns you to death. Hand Monster: If you make a loud noise, it turns that student into a painting. There are specific school rules, and you die if you don't follow them. Rules School Nurse: The infirmary is for people who are sick! If you aren't hurt... I'll make a wound for you!! (Kills if not injured) PE Teacher: It's PE class... why... aren't you wearing your gym clothes?! (Kills if not wearing gym clothes *Safe if wearing at least one item: sneakers, gym shirt, or gym pants) Science Teacher: If something big happens, tell the teacher, 'Teacher!! Please help me!!' But... you can't leave, right? Hehe. (Kills if you enter the science lab and then leave *Safe if you say 'Teacher!! Please help me!!') Hand Monster: It only has hands and turns the source of any sound into a painting. Conversely, to escape, you must go to the bottom floor, not the rooftop. *The school has changed into an endless maze.
