I think this anime really deserve better scoring than current measly 4.77.
Sound: The OST and the main song is hands down amazing and totally fitting the anime.
Art: I don't read comic books or anything like that but the art style is perfect for this kind of anime.
Story: A weak point... there is so many other stuff with superhero themes it's hard to see anything really new.
Characters: There is some great dynamic and banter between main cast but we don't really get to know them very well, at least not yet. But I certainly prefer them over any movie hero I saw till now.
I like how
laid back it all seems despite seriousness of the situations (Mushishi director's influence no doubt).
Enjoyment: I-Guy, I-Guy... :D
