Kita ze Inbou! - キタぜ陰謀!

I honestly don’t know what to say. Watching this trailer just blew me away because of it’s ridiculous good-looking action scenes and some rather provocative shots and mostly because I’m quite surprised at the amount of changes. From what I can tell this must be some kind of alternate story with the same characters as before. Here’s a synopsis from ANN:

It’s the future of New York. Kate, Rose, Rachel, and Claire lead the normal school life and a new transfer student comes… The transfer student, Louis wants to be friends with Kate. However, something happens to “Red Garden”. What is the truth behind this and the real purpose.

There’s also mecha in the OVA. o_o Interesting. Well, either way I’m quite looking forward to this OVA.
