I resisted until 6.3
There is nothing wrong with an arrogant and narcisistic MC. Fuutarou from Quintessential Quintuplets started out as arrogant, so did the MC from Amabri.
There is also NOTHING, and I really do mean nothing, wrong about OP main characters. Saitama is the clearest example that comes to mind, but surely others can think of other examples.
Why wouldn't an OP protagonist be arrogant? He is literally the greatest, after all. A lot of Wuxias (the chinese webtoons), have protagonists with those characteristics, and some of them are more bearable than their Japanese counterparts with their fake humbleness.
Why, however, do I (and probably many others) have to repress the urge to throw my smartphone out of the window when these people act like themselves?
Simple, really: they face no consequence for their behaviour. Nobody gets legitimately angry for being constantly patronized by these pricks, and those that do are the baddies anyway.
Worst yet, most of the attractive female cast (and also some males cuz some people still think gay=funny) showers them with attention, because very small acts of kindness that should be basic level for anyone above the status of sociopath TOOOOOTALLY make up for constant, shit behaviour, and suddenly they care for their friends or whatever. They act like they have no peer, but then they get invested in the misadventures of the rest of the cast? WHAT?
Dear reader, from the papyrus above you definitely already know my main gripe with this manga. The main guy is an annoying, arrogant a-hole, who constantly belittles those around him, wether in thoughts, words or actions, solves aaaalllll their problems for them, manipulates them and these supposed "Heavenly Kings" are unable to, nevermind call him out on, recognize the faults in his character outside of 2-panels-long gags. He chastises them for doing everything by themselves, but then he single handedly saves the day. I was hoping that, at the very least, the dinner scene would have exposed some serious lack in his social skills, but noooooooope, he effortlessly charms the girl and then is saved right before he could've faced the consequences. Will this manga get better? Idk, but from my glimpse at 7.1 sure looks like these patterns will repeat themselves.
4/10, for the thickest of skins only.
