A bunch of students dying because of random things
DTB Chinese Electric Batman killing everyone because he can xD
The Reason every student died once in a while was because of a curse that was brought unintentionally by an extra,a person that theoretically died but somehow came back to life.You can tell who that extra when that person is killed and everybody suddenly starts to forget that person like it never existed,its possibly the reason why the anime is called "Another".
Just if you were curious,smily boi.
Say what you feel,it's not being rude.It's being real.
