The main characters are boring, the females characters are only there for fanservice … literally. I don't know but it's like that this anime was created on a single thought: "Give those girls a gun!". Almost every bad guy is half rapist and half crazy; every innocent girl gets stripped by their attackers and every time we have to deal with some sort of thriller background (the series tried to be serious on its themes but failed).
In this anime the CG is used. It sucks.
The fighting choreography is lousy and the dialogues are written by an idiot. Hey, but at least is funny, right? ... No. No, it's not funny. Is nauseating.
