My One and Only Senpai

There was this school for anybody that are unique to be in. The schools had different types of groups though they were outsiders, youtubers, nerds, and more. Everyone was always in a group, there were no one alone. One day there were new students, they were known as the killers at there old school. No one knew why though. When the Killers get to there new school some people go missing and there might be some love rivals. Some people might want to watch their backs.
