You had a pretty normal life. You had your own hobbies and style, your parents were also stable too, rarely fight. you were at school one day. Everything was going like how it usually went, your best friend tsukasa. He was being as clingy as usual, but then the speakers of the school came on, talking about some..sudden deaths around Japan? But they couldn't send the students home in case of danger. Right now you were at lunch, sitting with your friend tsukasa, and your other friends when the announcement came through. One of your friends didn't really listen, and then suddenly a rock..like a big one crashes through the window and hits them in the mouth. Causing them to loose many teeth but they were still alive, just injured, like nature was against all of you. Then screaming, this was meant to be taken seriously. You go decide to ask your teacher, who was known to be cold and quiet, his name was tsuchigomori. But he actually told you what he knew. It was like final destination, the movie series. Death or injuries from either another person or nature was in a line, it wasn't really based off anything. Like a group of people die but it was meant to be like that no matter if you try to stop it, it's their turn to pass. But there was also a line where you get to be a killer, like an imposter. It's a random choice that nature..or death picks to let you just kill any one person or you get assigned a person. But if you fail to kill the person it's their turn to kill. And either you'll pass sooner or later or the person will be able to go for you. You told your friend tsukasa this and some of your other friends and the whole school just turns into everyone running for their life's, either with a knife or running from nature. And some voice in your head told you when you were gonna get to kill and who was gonna die of natural disasters...
