I really want the next chapter to be, this guy committed suicide to channel a demon, the demon recognizes the MC for what he is, and then flees immediately back to hell. The end.
It probably won't be that, but I really feel that's what it should be. I'm kind of biased though, I really like that scene from the I Stayed Behind And Became A Legend series, where the vampire lord calls out maijin from the dark dimension to attack the MC, but they recognize him as the guy who slaughtered millions of maijin in the dimensional rift and immediately nope the fuck out of there. There should be more scenes in manga where powerful or otherworldly forces recognize what an overpowered protagonist is and shit their pants.
