This is another strange one I picked up pretty randomly. It's basically the story of a mage who wants to destroy Earth with a huge hammer hanging in the orbit and knights who oppose him (mostly teenagers) with animal guardians. It's a very strange manga, quite psychological at times, funny and humorous and even dark and disturbing.
The trick is that the leader of the knights, Princess Samidare, actually wants to destroy Earth herself and is working with the main character, who gets pulled into the whole mess randomly.
Odd thing is I'm starting to symphatize with the knights after catching up on the series. Yuuhi is just an annoying SOB who makes me cringe, but maybe there will be a few twists along the way.
