Well, the MC has the appearance of the wizard king from Black Clover and has a proud and arrogant personality and will offend some people for relatively trivial things like simple insults directed at him, which is a bit annoying, but still, he is not the kind of evil protagonist who will chase and manipulate people all the time, he does not even look for a harem, which already makes him much better for me at least.The way the protagonist kills can be summed up with fire magic and the katana. So don't expect him to use ice, wind, earth, time and space spells or anything else to kill, at most he'll use some of them for support.He's still an OP character, but not an unstoppable one, he'll still bleed, faint, and lose from time to time.His "infinite mana" can best be described with the idea that his spells don't use mana from his mana pool when he uses them, but his mana pool isn't huge, so he needs to increase it to use more powerful spells, that's one of the reasons why he's not unstoppable but still OP, nice.Some fights are well described and even exciting, but unfortunately most are very rushed and just boil down to onomatopoeia or things like *crash* *dodge* *stab* and so on.Overall it's a good read, give it a try.
