A lot of Hanazawa's stories feature losers as protagonists, so it's not that surprising. I feel like I read somewhere once about how he doesn't think it's as exciting to write characters that aren't losers, because they're not normal enough. But I wouldn't know where to point, if you were to ask me.
Man, I thought Ikariishi was gonna clean up house, but he didn't even have to lift a fist on anyone. Murota is an annoying jackass, but chapters like this remind you that he's one of the bros. The way this one ended was just right.
