From what I heard, they left out many things that happened in the Manhwa probably because they wanted to focus on the most important stuff, so maybe there's more of the character development that wouldn't be that cliché (idk I haven't read it)
But even with the cliches and all I believe it's a really entertaining anime because it has the perfect amount of action and fantasy, making it an exciting story easy to watch. I would also give it a 9/10.
Nice review!
I don't know, I haven't seen the Manhwa either so I can't confirm anything, but well, as someone ignorant of the subject, I really liked the anime, to be honest. And yes, the amount of action and fantasy is excellent, as well as the quality of animation, which also stands out quite a bit.
Thanks for the support.
