Name of an anime that was possibly on Toonami?

i want to know the name of an anime that i watched when i was a bit younger. it was i think about a guy who lived with like 4 or 5 girls who had special powers or abilities. one was like a princess with magic powers, one was a mad scientist, one had some kind of space rabbit that could turn into a giant mecha robot, one was just a dumb blonde chick, and the other i can't remember what she could do. and i think the grandfather was a priest or something.
