You know, I didn't expect I'd give this manga it's highest written review rating, but I can see why. This manga stumbles hard in the beginning, but enduring the first 18 chapters will let you see the beginning of what this manga blooms into: a battle-crazed MC pushing his limits in another world while both embracing and destroying various isekai tropes.
Yeah, the art isn't the most "proportionally correct" (as if that's ever a thing in most manga) and in the beginning it's slightly better than amateur. But it gets far better over time as the artist begins to develop a style similar to One Piece (but less exaggerated in both how narrow the stomach/waists are and how "thicc" the "thicc" parts are), then use that as a base to develop an even better style. Personally, in the later chapters, I think it's more appealing than the style of One Piece.
The line art is clean throughout (not fuzzy), and as the artist comes into their own, the art will probably grow on you. I actually really like it in the later chapters.
The writing can be really janky at times, especially in the beginning. Yeah, the cringe is horrible. But as the plot develops, the writing improves and it becomes bearable.
So why did I stick it out past 18 chapters? There's an intangible quality that's greater than the sum of its parts, and it ended up paying off for me.
This one is a strong recommend, but you have to be willing to endure the sandpaper this initially puts to your brain. Kind of like the first several episodes of Eureka 7.
