PLEASE they better admit that there terrible parents next chapter. Cuz were gonna be dealing with the most dense mc of all time because of them. And it gonna annoy the shit out of me
I'm betting this gets axed before the mc ever realizes or accepts how powerful he is. This whole manga seems like it hinges on him being dense and aggravating asf .so dont expect any real developments with this.
So basically

mix with Magi's Grandson
It's gonna be annoying if the misunderstanding/dense mc theme is consistent. It's the reason I could never come to like the manga that whimsicat linked.
@Hamin Although it's tagged as isekai, it's not exactly correct, since (until now) there have been no characters transported to different worlds. It's either miss-tagged or the story is just explaining something really late.
Anyways, to answer your question, it's because isekais are basically just wish fulfillment, so why not use tropes that would fit that category, like a completely OP Mc.
Getting an outside opinion and ensuring hell behaves for a few more decades at the same time, clever. At this point the kid isn't dense, hes ignorant. His own parents have told him he is above average at best and he has seen nothing to tell him otherwise.
