Wow, that girl-the teacher isn't like protecting the kids from bad alduts. Some of them don't want to murder chop off people. She forced them to do it and if they refuse, she will kill them. This makes what the emo boy said from chapter 3 make sense when she got soft on Tooru "Doesn't that make all the kids who have been disposed of so far look like idiots?". I thought she was on their side, WHAT A FUCKING DISGUSTING BITCH!
I think this child care facility allows kids who have no where to go to stay for a price, and there are someone behind all of this. At first, I thought the teacher and the kids kill all other adults work in the facility and took over the place.
