One of the best manga i ever read. the story is very great and cool. the art is not that great but acceptable. there is so many great and cool character here. but there is some annoying thing in this manga that like:
(1) yuyaa girl commenting every battle like a mother watch his son crossing the road.
(2) many unimportant battle between main character and weaklings.
(3) the battle scene is very boring. im not gonna lie. its very very very boring.
(4) Most of the cool character are friend. so you cant see many awesome villains until halfway of the story.
But if you like a good story with great ending and some cool character, this manga is worth a read
