If you wanna watch an anime that has Shakugan no Shana fight & Zero no Tsukaima love relationship style i strongly recommend for u (mina san!) to watch this anime. real fun ecchi!

The main character is told he will die soon if he dosent help the female lead. later find out he has some thing special hidden in his body.
