Minky Momo travels through time and teams up with her previous magical princess self to help an old man.

It is said that train stations are not only an end and a beginning for many, but also are a place for lost and forgotten objects - and for those who are forgotten. On a rain-soaked day, Minky Momo rides the train towards her final destination and converses with an old man who is trying to reunite with someone very important to him. After discovering he left his passport on the train, Momo embarks to try to find him and consequently runs into both her parallel self, and a young girl who is in need of both of their help.—Tenchi
