Six spirits inhabit the trains of Tokyo's Oedo subway line, and they're on a mission to help lost passengers find their way. Fumi works the platforms with cheerful energy, while Rintarou keeps watch from the shadows. Izayoi, Iku, Saki, and Itsumi round out this unlikely crew of supernatural guardians, each bringing their own quirks and histories to their stations. When troubled commuters board these trains, they rarely realize they're about to encounter something beyond the ordinary. A chance conversation, a cryptic piece of advice, or an unexpected encounter becomes the catalyst for change. The spirits don't just help people reach their destinations. They help them reach themselves. Each episode rides a different emotional frequency, blending the supernatural with deeply human problems. You'll find yourself following characters whose lives pivot on small, ordinary train rides that turn out to be anything but. The Oedo line becomes a space where loneliness gets confronted, regrets get reframed, and second chances board at the next stop.
