Battle Royal High School was one of the bloodiest and action packed fighting shows I have seen in a while. There is no clear cut lines between who is good and who is bad. Just a lot of punching, kicking, and body parts. This OVA incorporated a number of different aspects including martial arts, demons, and cool cyber suits. Although the elements may sound like a weird combination, they seem to go quite well together.
For anyone who like early 90s style animation with senseless violence, check this one out for sure.
