@TNT261 lol, I actually saw this episode of black mirror and even though i see what you mean it's really science fiction and in no way an example to use. The elements you pointed out are all good, but they contradict other points of the story. His whole family is op, but why is his sister so knowledgeable in comparison to him. If what you say about his over protective parents is true then she should be dumb as well (at least to some degree). How come his father is the ultimate hero everyone knows and he is friends with all the nobles etc. yet he was let go because some kid "applied pressure" on his company. And how is a stupid kid able to do that in the first place. He doesn't look so notorious when he has to publicly apologize.
And mc's family got nobility titles in heartbeat, yet the notorious hero who has slain really powerful monsters is let go from his (probably shitty) job because of a kid who was killed in 1 second by the sister. How come he didn't get any recognition up to now, and suddenly wants to becomes a noble. The notoriety of the people in this manga changes every chapter, it's just ridiculous.
And mc being so op. Do you think it's logical that, when they started beating him up he looked so weak and got bruised all over (probably for the drama), yet when he was his by a sword and by a demon he doesn't even flinch? Are you gonna tell me it's not farfetched to be this passive when he definitely seems to know he is one of the strongest person alive?
I could keep going but i think i've made my point. I'm not saying it's totally impossible, but it's so farfetched in order to make some drama and comedy that it's stupid.
