Three good-hearted sisters, Ai, Mai, and Mii, live in a house that travels through time. They stop every so often to help whomever they can with a mix of silliness and sexiness. Traveling with them is their android maid, Mea, who sometimes appears to be the only one without her head in the clouds. The sisters try to leave things better and happier each time they depart from a new place, but they seldom get a chance to see the effects of their help before they're off to the next destination.
