This is anime is so bad you'll absolutely love it. It has no story to offer, no beautiful art , no interesting characters. It's so horribly bad it's awesome. It's just something you need to watch with your friends.
I recommend to search it on youtube and watch the one with English subs. It makes the show so much more awesome!
If you want to watch it for the ecchi, like mentioned above, you shouldn't try to watch it, the same for the people who want content. You will not get any backstory at all, no introduction, the fighting is nice. Go otter!
