I can finally scratch the itch that's been bugging me since I read chapter three of this thing idk how long ago that was: every newly introduced situation here is ephemeral and did not establish anything but a setting.
Problems here just rise and pop. They really just appear for the sake of narrative, except since there's not really any status quo, they just keep coming back to the rapist dad being killed (this being the fundamental status quo rather than whatever's happening) and everybody else go on a quick deprecation regarding death, either for themselves or others. Then a new problem appears for the narrative. Rinse and repeat. Nobody really learns anything except, again, for the narrative.
All this said, I'm definitely sticking to my seat on this trainwreck for at least a couple more chapters. Now that all mysteries about Shiika is answered I really have no idea where this is gonna go next.
