Three sisters, Ai, Mai, and Mii, along with their housekeeper android Mea live in a large, time-travelling house. The story follows the sisters' journey through time and space as they, with the assistance of communicating dandelions (referred to here as "popotan"), seek out a certain mysterious someone believed to hold the answers to their questions. Emotions begin to run high as the girls are challenged by an inherent fact of their situation: they will abandon anyone they meet... or worse, befriend. |
