Da! Da! Da!, as the title would probably suggest, is not the most intellectually challenging anime in the world. A western (I think) girl comes to live with a boy in a Japanese shrine. These two junior high students are living alone together, when suddenly an alien spaceship crashes, and out comes a flying baby boy with telekinetic powers, and his cat/toy/butler thing that can transform to look like anything it wants. And the story goes on from there... -_-;;;
