This is dumb. In what world Paralysis, Poison & Sleep are useless? They are the most common OP abilities (beside overly OP abilities like Invincibility, immortality, etc.)
As usual, there is a sexy girl/elf following the main character within the 10 first chapters.
Everything else is straight from the book. EVERY trope from the Isekai / revenge story without a drop of originality.
It is on the level of a PARODY except that it takes its story seriously. Obviously, it has to be an Isekai world working like a Video Game, which is utterly stupid, video game mechanics exists to reproduce reality, not to display another reality. Levels & Skills illustrate experience & talents, they do not REPLACE them. Once or twice it was original but now it is downright stupid (especially because they won't do anything original with it).
PS: Lvl 1 to 258, AWESOME, I have no idea how levels work and whether or not level 258 is high. Plus, numbers don't replace narration. To say that X is level 200, Y is SSS Rank isn't good narration, give us something to consider them awesome except lazy exposition. Some Jirocho type of introduction where you know right away that not only is he badass but he was scaled based on our already asserted badass main character (Gintoki from Gintama). Characters' actions & reactions bring some decent narration & cool characters, levels & ranks don't.
Pretty drawing but story-wise it is lazy.
This is my sole opinion but for me, it is trash. Nothing's worth saving (except drawings but at some point, you should care about the story & characters too...)
Sorry, I know that I am ranting but lately fantasy manga all look the same. Those are not even relying on good tropes (MC surrounded by a slave, pretty girls, etc. and all of them are either overly friendly or enamored with him even though MC is a blank slate.)
