Dororo is one of Tezuka Osamu's darker works, and I'm honestly not sure what the author was aiming for here. Anyway, this was released by Vertical in 3 separate volumes, instead of 4. Vertical's release features a new cover design, which is possibly the worst cover design I've ever seen. Describe the cover?
Imagine taking random panels of manga and pasting it onto some human flesh.
Cool,right? No, not at all.
What happens when you combine Disney with rather violent fight scene? You get a manga like Dororo. The monsters are awesomely designed, while the humans are rather boring, and just unimpressive. The violent action scene lack detail and the panels are too small of its own good. But it does create a rather interesting atmosphere....
I wouldn't say that they're anything special, but Dororo is a really cute character, and is more than I can say for the rest of the cast. I guess Hyakkimaru is cool, but he's not a very deep character. Can't really say much for the side characters since they're just kind of there....
It's really fun and fast paced. Dororo is full of action and cool monsters. Dororo is episodic, ignoring some slight continuation. But these words of praise on apply to the first 2 volumes, while the final volume is a poorly written mess. The 3rd volume introduces possible new allies, only to kill them off at the last possible moment, because writing in a new character is hard.
It's just really incomplete as a whole.
It was fun, certainly not worth the money, though. Plenty of better samurai vs youkai/monster stuff out there.
