Omg the ghost boy lmao) SO a demonic voice told everybody to go downstairs to the office lobby it's a broken screen on the floor with a black and yellow bear and a black and white bird named Monoboss and Monocrow they both took turns explaining why are they stuck in the office building. They're all here for a killing game that they were dragged into Monocrow explains the killing game and then the rules after that the students are left free to explore something by Haruki: "Have fun kids!" (there wasn't enough to add 17 lol)
