The storytelling followed a very typical shonen style. The main characters continuously level up in battles, learning to better cooperate and utilize their abilities, while also getting trustworthy teammates (with tragic backstories). Even the occasional sexual harassment jokes are so typical (in a bad way) - but fortunately, it gradually shifted away from such jokes and moved towards proper world and character building.
The anime adaption left me with mixed feelings. There were highlights in the beginning, but were soon buried in numerous disappointing moments spanning two seasons. The pacing was inconsistent - sometimes a story was rushed, while sometimes the plot moved unbearably slow with tons of flashbacks, repeated scenes, and recaps. There were excessive amount of narration, and they were often disjointed from the visuals. (Yes, those narrations existed in manga as well - but a good adaption is supposed to make adjustments according to the medium!)
I would still recommend watching it, just for the story; having a lower expectation would likely make it more pleasant to watch.
