Among Tokyo's subway lines is a train where passengers are met by the six human manifestations of the Oedo Line stations: Roppongi, Tocho-Mae, Shinjuku, Tsukishima, Shiodome, and Ryogoku.
A businesswoman named Mai boards the Miracle Train at the Tocho-Mae station, but she insists that she's already solved the problem that brought her there.
A woman dressed in an extravagant gown tries to get through the Tsukishima station ticket gate, and Tsukishima ends up guiding her aboard the Miracle Train to protect her from some suspicious men.
The stations try to give a warm welcome to their young passenger from Roppongi station, Airi, and also attempt to figure out why she ran away from home.
Mayu always helps those in need, which makes her late to all of her appointments; but today, she's determined to get to Roppongi station in time, and the stations decide to lend a hand.
