perspective of the three sisters and their maid rather than the game's protagonist; all the game's major female characters appear and many of the minor characters are used in supporting or cameo roles. The story centers around the three sisters as they travel through time in a mansion, run a Christmas shop, and search for the dandelion-resembling "popotan". The sisters interact with others and try to improve their situations. The anime suggests that others, including the antagonist Keith, have attempted similar journeys in the past. The anime otherwise covers little backstory, obscuring the reason for why Shizuku, Keith and Mea are associated. The sisters meet Shizuku while traveling through time, who gives them the option to continue journeying or stay in the era they enjoy most; they choose the former. The story ends as they continue traveling through time, leaving unanswered questions concerning their final destination and why they were chosen. Their bodies are connected to the mansion where they live, which allows them to travel through time. Their bodies cease to age outside the mansion; even their hair stops growing. They jump five years into the future when traveling through time and always arrive in different places, except for a split-party scenario in which Mai and Mea are left behind.
