1)Story: This series is more action/comedy than real deep character backgrounds. Its a small series to enjoy and laugh pretty hard in some episodes but last 4 episodes was seriously hollow.
2)Art: Amazing anime-to-manga transfers in one punch kill scenes and pretty nice characters
3)Sound: Loving the intro and generally all music in it but the soundtrack is seriously small.
4)Character: No background or aaaanything at all about characters.
5)Enjoyment: I dont look for deep characters in animes.Im more of a have fun kind of a guy. For example danshi koukusei no nichijou had no story and little background but still loved it.
6) Overall:Had my fun but im not sure about people who look for deep stories and big character backgrounds.
