Mezzo forte is a nice little action, comedy. The animation flows like water. The guns are well displayed, and Mkura is one of my favorite characters ever. The fight scenes were some of the best I've seen in any anime, rivaling that of Cowboy Bebop.
Now to the bad news. The story is okay, but many things don't seem to come all the way together. Like Mikura's ability to tell the future at random moments. If you're asking, "How can she do that?", your question will never be answered. Many others have commented on the rape scenes, and I must agree that they are totally out of place here. Somewhere between the guy getting hit in the balls with a baseball, and some other guy running out of the bathroom stall with his pants falling down in fear, the scenes don't fit in at all. Also the sound design isn't up to par for modern times at all. The music sucks also.
