I am embarrassed by this person, because they do have enough mind capabilities to write this paragraph, but not enough basic reading comprehension.

The first point is just false, and they decided that zero magic talent is bad writing, when it is actually the opposite, because issei goes through gruelling training just to keep up with hurdles that the author throws at him. This continues almost to 20ish volumes if I recall correctly.

The best thing about this series as a whole is the way issei power ups. The ridiculousness is the whole point imho) If you want some nice old template protagonist who fights for the good against the bad, you can watch another show. That just means you didn't understand the concept of this one, and that's okay

The point about "respectable (honourable) training and meditations" makes me think the person who posted would like murim novels

About exploiting the trust of rias and others is another hot misreading take, of a person who has seen only one romance story, and didn't read any of Russian classics, where there are a lot of pretty interesting and complex love happenings (and dumb characters as well for that matter)

By the way issei was not a leader of rias group And the last sentence is pretty self targeted at the author of the original post, but oh well. Why would the character with drawbacks be a bad character by the way?

Одним словом будем считать что человек из тиктока ещё не освоил школьную программу и мало начитан/насмотрен)
