Can't Remember a Title

Okay, so there's this animated film I watched a while back that I hugely enjoyed, and now I can't seem to remember the name. But I think it starts with a "K"... Anyway.

It's actually a couple or three OVA's that they combined into one to make a movie, but the movie is in 2 parts. I believe the 2nd part either just came out or is coming out soon. I do know that it's about this guy who wakes up to realize he's been chosen to be this sort of protector of a certain town. These protectors(I don't remember what they're called, seeing as it's the name of the movie itself) have a partner, always female, that allows the protectors to take a certain form, which has a variety of majorly awesome abilities. I know they can like transform, sorta like transformers, into a plane form and a car form(loosely...)... And I know that these protectors are numerous and each one has dominion over a certain region. That's pretty much it...

I'd really appreciate any help in figuring out the name of this damn movie. >.<
