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.
