I'm just reading it for the loli demon lord, tbh. Probably the only nice thing about this all over the place title. He did say that he'd go with them, to be fair.
But it was somewhat fresh up until the second arc. Now it's run-of-the-mill lame fantasy isekai. That is, now it's not original at all and the author's lack of skill is just too apparent, imho.
Plz kill this strong body of his. I'd ask to kill generic tiddy-girl Bobby too, but ppl seem to like her tiddies, so meh. Such stories really need MC to solo to work, y'know. Like, really.
