nagumo is obviously the bobbed hair girl from the photo??? dark hair, bangs... typical vengeance ghost shit going on. maybe she was some friend they all forgot or got killed in that factory/processed into food for everyone and they all ate her so she came back as a cannibal ghost to punish them
So, they were throwing darts at pictures, even though there are only 2 females left, and the other female's picture wasn't even on the board? Makes sense.
That sounds about right. And really, what else could it be? According to the yearbook pictures at the start of the chapter, Nagumo is the only person left besides the MC's group.
...Okay, where are the teachers again? Does everyone just go to school, and it's empty? Sounds kind of... stupid. And very convienent. Maybe this was explained in an earlier chapter and I just can't remember.
Man this is so stupid. I can't wait for new chapters. This is like reading gal cleaning while it was coming out. A trainwreck. but one i wanted to see.
