You're reading normally, another sekai story, with magic, dragons, etc... And out of nowhere, the mangaka changes, the style is more "lively", different... but so far ok.
The story has its good and bad peaks, no big deal, the protagonist can't get anyone, the romance is tedious, there's more focus on the character and how unstoppable he is... almost that isekai, of the girl who is full defense.
But if I focus only on the first part, of the first style of the manga, then yes, he is very good, he is not an overlord of life, but he is good... in the first few caps he is really good... It catches you in several moments of the narrative, but from there it's just decay....
