More than standard "these are terrible people" reactions the classmates give, the flashback this time has kind of horrified me with both the upsetting methods of abusing innocents for profit (I didn't ever consider this kind of thing was possible), but also leaves me wondering if the hometown they all came from in our world isn't just as messed up as the classmates have been...
I know revenge stories are built on there being crappy people for us to root against as the lead gets revenge, but it feels like this series is about one guy, his dead sister, and the evil nightmare people that make up the rest of the world.
