Miracle Train: Welcome to Chuo Line presents a different narrative installment. While Miracle Train initially focused on the stations of the central Chuo route, the latest animated series and corresponding plots center around the Oedo subway line. As a result, a new group of characters will make their debut in the anime, including Fumi Roppongi, Rintarou Shinjuku, Izayoi Tsukishima, Iku Shiodome, Saki Tochou, and Itsumi Ryougoku.
