Popotan(2003)

Popotan is a magical-realist anime series following three sisters—Ai, Mai, and Mii—alongside their android maid Mea and a mischievous ferret named Unagi. Their mansion inexplicably travels through time and space, allowing them to chase a mysterious dandelion-like entity called Popotan in search of answers to deeply personal questions. Along the way, the group opens a Christmas shop, visits hot springs, and makes fleeting friendships in each era they visit. The tone balances whimsy and melancholy: while the journey brims with humor and adventure, the girls must confront the bittersweet reality of leaving companions behind as they move forward through time. Popotan blends slice-of-life charm with genuine emotional weight, exploring themes of connection, loss, and self-discovery across its episodic narrative.
