After a few chapters, you notice this series is an affectionate parody of high fantasy settings with OP MCs. Every cliché trope you can imagine will be referenced, and if one of the characters doesn't point the falls in logic said trope has, then be sure the narrator himself will.

Lloyd is your typical nice guy MC, but he's so extremely OP to the point that he can defeat demon lords with little difficulty - however, the catch with him is that he comes from a village of legendary heroes where he was raised by a god, so he was labelled as the weakest on that village, which led to his perception of power being so disturbed that he considers stuff like 10 meter tall monsters to be simple bugs. He's basically an anti-thesis to Saitama in that way, he defeats everyone effortlessly if not downright one-shot, but he doesn't even notice as much due to his weird upraising.

Every other main character also has a main joke to them: Marie has being hilariously abused by her master's magic, Riho is only in it for the money, Selen is a yandere stalker who can't think of anything but Lloyd, Alka is a 100+ years old loli who is a shotacon, and Phyllo is a girl of few words that has problems following the flow of normal conversations which leads her to wrong conclusions. Expect to see the author looking for ways to milk every one of those jokes for what's worth.

Overall, this is a fairly good comedy novel, but unless that mysterious villain working in the background manages to eventually shake the status quo, I can see this basically going the same route as One Punch Man of simply overusing their jokes as much as they can.
