This anime is about three sisters who live together with their maid in a house that travels from place to place.

The sisters are: Ai, the typical large-breasted oldest sister, with the power to talk with flowers. Mai, the typical athletic high-schooler, with the power to, well, do impossible athletic moves, and Mii, the typical cute little sister, a "magical girl" with the power to heal. Mare their android maid, prefers her time off, is a glutton, and cannot resist sarcastic comments.

Every episode involves the girls making friends at a different place while they are ultimately seeking something that only the Popotan (their name for dandelions) know about.
