mha killer

sooo theres a killer in mha (be whoever) again, im not listing the characters im so damn tired! anyway story: so you guys were just chilling (and yes, mina forced all of you to another sleep over) and you all are playing on the x box (your choice if you are or not) when there is suddenly a knock on the door, kirishima and the others tell mina to go check (also you guys are upstairs) anyway so mina went downstairs to open the door until... 35 minutes past and she still doesnt come..
