Battle Royal High School what a fucking trip this hour-long anime is. If you like very mindless, over-the-top, and violent anime, this should be on your list. This is what happens if you mix in everything and the kitchen sink to shock and confuse the viewer. There are hints of Fist of The North Star and horror movies like The Thing, hell even The Toxic Avenger. What gives this anime only an 8 is that it's way too short and the endings very abrupt, if 20 or 30 more minutes was added in it would be a 9.5 or a 10. If you're a fanof over-the-top OVA cheesiness with gore, then this is the anime for you my friend.
