Fractale

They're both by the same director to begin with, giving them a very similar feel. They both also have a girl with special powers of some sort, the full extent of those powers unknown, meeting up with the main character. They both also have rather good animation too. Kannagi is a slice-of-life anime though, while Fractale is a sci-fi in a fantasy like world that actually has a plot.
