there isn't really much to say about this manga.
it has some very good moment, thought most of the manga's battles and plot is just alright.
problems i've had:
-is that there are way too many characters (in fact, almost always bad guy turn out to be good guys gone wrong, and in the end side up with the hero), and i couldn't really feel sympathetic with most of them.
-repetitive gags, and sometimes the humor just doesn't make much sense: it's like a comedian that hopes for a piety laugh because he said poop in front of everybody.
-too many good sentiments. i dunno how to explain, there really is to much love, and everyone is real nice, even bad guys aren't really bad, nothing's anybody's faults, nobody dies even if their body gets disintegrated, or incenerated or stuff. too much "wanna save the world, do the right thing, and be back home before sister worries" kind of stuff...
i think it's a great manga if you're young, or if you haven't read that many. else, look elsewhere.
