(ok so i have not read the manga and don't plan on it) the date today is 2016 march 4 and i saw episode 9 and spoiler!!!! at the end of the episode we see his classmate in class with a red back pack and many signs in this show are not true at all but she has a red backpack like the 2nd target so i have a theory. since he is protecting the next target the killer will pick a new one which is her. but then i thought since there is no first target there must be a first so the killer hasn't started yet but he will with the girl at the end of episode 9
