This is what i remember of he anime:
It's genre is sci-fi, and it's a mix between action and romance.

It's about a group military students who gets sent to a spaceplatform to recieve special training there, but while they're at the platform, they get attacked by terrorists, and they discover more and more things in the process.

I don't want to write much more, since i want to watch the series again, and don't want to remember all to much.

It's not more than max 20 episodes.
