Merc100

There is an anime that I wanted to find that I can't remember. It is a fan service anime that has alot of clothes damage. Its about an all girl school that could be a military school, they fight in an arena that has low gravity or zero gravity and they fight with weapons I think or maybe just punching and kicking but every attack would rip part of their opponents clothing and I believe once all their clothes are ripped off they lose. It is not sekirei, freezing, or the one that has the firls in the swimsuits that hit eachother with their butts. It is not the usual anime suggestions that people suggest when I ask this. The main girl character has silver or blue hair I believe. I need help finding this anime and have been trying for a couple years. Please help me I beg you. It also might be a ecchi or dam near close to hentai but it's not hentai so I just can't find it. It is none of the usual animes people suggest and people have suggested the same ones but a few new ones and none of them are right this is starting to bug me and I really hope I can find it....
