The characters, particularly the villains, no substance for the first tome but it improves later (with some Homeric fighting in Volume 3!).
2 nevertheless regrets compared to the first edition (unfinished) 90s: the margin "eats" the 5mm picture up and down and onomatopoeia are in Japanese as they were all in French for the 1st edition (which was done impeccably respecting the original design or by making it more readable).
This paper we prefer manga far its animated version whose fights are very watered down and the scenario not always respected in relation to the original.
