Simply put, it's the logical conclusion of isekai. It is to isekai as one punch man is to shonen. It's plot and characters are nothing to write home about but its art is very good and the resulting story is hilarious. It's really just what you get when you smash a bunch of isekai tropes together with a guy who kinda accidentally tends to knock them askew by the sheer fact that his power is stupidly over powered and I'm here for it. There are a couple vaguely interesting story beats, namely the mc's backstory and how the people related to him react to it, and howdifferent people react to what's basically the grim reaper just chilling next to them is interesting as well. Other than that it's relatively blase.

I enjoy it a lot, probably have read it fully twice now and once I've finished this review I'm probably gonna read it again.

also akasa-san ~= kobeni so I absolutely love her character
