In my opinion, there are stuff missing. It's so good, that it's almost peak
Like, if it was another concept, with the same pacing and the same plot points, I would genuinely also say it's ass
But because the world is cool, the mc power, and his overpowered "master", his rage (in the beginning at least) (thats also the thing, he's so go-lucky now, i don't like it, I liked it when he was full of anger and rage in the beginning)
Like the things that work, they're freaking great
But a bunch of things don't work, so it doesn't reach peak level, I think

this is so ass
my opinion<3
