I've been hearing lots and lots of talk about this OAV for a while now and I've been trying like hell to find it. I eventually managed to download it completely uncut (in Japanese) which is the way to see it. It does not disappoint.
In the tradition of live-action films such as Baise Moi, Mezzo infuses graphic sexual content (i.e. penetration) in its run, which is why this film has garnered lots of buzz in the anime circles. Now, it could have done without the sex scenes but it doesn't make it any worse. The action is plentiful and crazy with cute chic Mikura blasting bad guys with the ferocity and gracefulness of Chow Yun-Fat. Momoni adds an interesting balance between her psychotic, sadistic, rage-induced violent tendencies and Mikura's reactive, poetic destructiveness. In the end this is a bloody, sex-filled romp through familiar territory but with enough humor and explosions to make it interesting.
