The hero's party is painted as unambiguous douchbags. The protagonist is painted as a sympathetic victim. The protagonist also is the sole reason the party has gained success, and this is obvious to anyone in the audience with half a brain. Hmm, where have we heard this plot before? No idea, what a novel and original concept!
Everyone—but the protagonist and waifu harem—is retarded and can't understand basic cause and effect until it's too late or not at all: except for the reality that everyone is actually retarded, including the protagonist with all his literal infinite wisdom and skills could not anticipate the consequences of his actions. Anyone who's not a midwit will notice the protagonist is also a terrible person, e.g. 'uhm ackchually it's compound interest betcha didn't know that huh! so guess what you're in perma debt now lol!' Can't forget torturing a guy over a girl you just met. You're not supposed to notice this because you should be feeling sympathetic and root for him, it's all "justified".
Oh, and big numbers! Because he can't be a relatable protagonist without them! All that's missing is a cut and paste exposition prologue chapter telling you it's an isekai, because chapter 2 is just explaining how cool he is for killing this throwaway god-like enemy with his exponentially plotted powerlevel. This is all in the first few chapters too.
Just keep ticking those boxes. Dipshit party kicks him out? Check. Supermegahax OP protag? Check. Simple problems to "bite" him later? Check. Waifu? Check. Another waifu but she's an animal girl, who's discriminated against AND TREATED LIKE A SLAVE!? Check. Villains are loud obnoxious idiots? Check. No stakes? Check. Terrible writing? Check.
There's worse manga, easily. And there's loads of better ones, even if you're just in it for waifu bait. That's not saying much when this one has no redeeming qualities. Read this if you're just starting out reading manga, or have literally nothing else to read.
