This anime is about three sisters who live together with their maid in a house that seems to travel from place to place.
The sisters are Ai, the typical big-breasted oldest sister, with the power to talk with flowers, Mai, the typical athletic high-schooler, with the power to, well, do impossible athletic stuff and Mii, the typical cute little sister, with the power to heal. Their maid is Mare, who looks kinda robotic.
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) hold informations about.
