This movie is about fighting. I can tell you that without spoiling anything, this movie mainly consists of 2 two fights in an arena. And guess what? In 45min minutes that is quite a good entertainment. The first fight is OK and has some surprises and the second one gets weird with strange techniques and stuff. The animation itself was well done. 45min is a short time for a story to develop so there isn't really much going on besides fighting. What bothered me was a bit the slight homo-erotic components and transgender looks of the second fighter, that made this anime kinda weird. But still it's enjoyable, if you're in the mood for a not so long anime and you like fighting-sports you can watch this.
