Aight. Lemme get this straight and out of my chest:
• Pros:
- Most characters are interesting in some way, and have good development within the story.
- The plot is actually quite good, and doesn't have loose ends or contradictions like most of the similar shounens.
- For a battle heavy shounen, the characters and the scenery are well drawn, and it helps a lot in the beggining. Later it changes to a more generic art style, but still quite good.
• Cons:
- The unnecessary ecchi during the whole manga, but mainly in the beginning, is stupid. If you don't care, it's not a con, and at least it both has a reason and gets less frequent, but it makes the main female, a very bad character, and she doesn't get much better, sadly.
- The pacing is TERRIBLE. The story is good, but how it's told... sadly, is not. If this manga had a better pacing, it would be WAAAAAAAY better.
- Most of the fights are senseless, and full of DBZ syndrome. Forced powerups, cliché dialogues, and there's no outsmarting the enemy, there's only brute force. The most you get of a battle tactic, are gimmicks and Ban making some smart usage of his power.
- The fight against the Demon Lord is "all the bad things about this manga, the arc".
- Arthur deserved more.
--------------
Overall, it has more cons than pros, but don't get me wrong, I find it an actually good manga. It's just a shame that it could've been much, MUCH better if the author and/or the editor/manager (idk), were less focused on making it battle heavy, and let the story flow naturally. Sigh... a shame.
Personally, 8/10, I liked it quite a bit.
Critically? Either 6 or 7/10.
