Japanese urban legend speaks of an underground train that runs without any limits, ridden only by beautiful young men, and anyone lucky enough to find it is said to become truly happy. When a woman is weighed down by anxieties and self-doubt, a beam of light grants her entry to the Oedo Line platform, where the Miracle Train waits. Inside are six good-looking young men named after stations on the line: Fumi Roppongi, Rintarou Shinjuku, Izayoi Tsukishima, Iku Shiodome, Saki Tochou, and Itsumi Ryougoku. Their personalities differ, but they share a close bond, and together they set out to wipe away the fears of the women who come aboard. A fantasy reworking of the Miracle Train franchise, this version moves the setting from the Chuo line to the Oedo subway line and brings in a new cast.
