I don't really want to say it, but Himenois literally that same kind of evil as Hitler; good intentions, exceedingly horrible execution that relies on subjugation. Sure, the train groper deserves to get turned in, but being surrounded by ass knives? Threatened with death or subservience? Those two guys who were too nervous to say anything also getting equally harsh treatment? There's some parallels to events I'd rather not mention going on. The whole of that city sounds like the worst place on earth.
I fully support the new girl's drive to kill the badly written protagonist, but you just know she's going to get friend zoned at some point. No way she's going to succeed.
