Could have been a good story, but as is usual for these Japanese MCs with a hard-on for being "normal", the MC here is willing to do anything to survive, up to and including sacrificing every shred of dignity to boot lick the Original Protagonist and going out of his way to be as worthless and "mob-like" as possible.
And this is despite him clearly being OP.
And then going further, because obviously it's "comedy" this MC is as dense and ignorant as a black star, he simply cannot get his words out right amidst all the stuttering, causing other people to misunderstand him CONSTANTLY, or CONSTANTLY misunderstanding people because of how utterly IGNORANT he is, but that's basically par for the course when it comes to Japanese MCs, regardless of their type.
