A new one: NyanKoi! (comedy, school life, romance, supernatural, cats, harem)
A story about Kousaka Junpei, a boy that's allergic to cat's fur, but due to a small accident, he's cursed by the cat god. In order to remove the curse, he has to do good deeds to cats, otherwise he'll slowly turn into a cat (Well, with the allergy he has, that means DEATH!).
I love comedy!
