Two siblings were happy on Mt. Olympus, until they fell in love. Deimo's sister Venus got imprisoned in the Swamp of Death. To save Venus's life, he must find a human reincarnation so that they can continue their love.

There are some things that people are unable to say while they are alive; for these, there are "shigofumi," letters carried from the world of the dead to the world of the living. When a person with strong emotions dies, they are able to create a shigofumi, whether their feelings are of love, longing, or resentment. It is the quiet and mysterious Fumika's job to deliver these messages from the departed. Along with her talking magic staff Kanaka, she ensures that each shigofumi reaches its intended recipient, even if that person does not want to face its contents. Fumika witnesses the tragedies of people, both dead and alive, and sees their deepest secrets revealed. What is unclear, however, are the details of Fumika's past. Who was she before she came to be a carrier of shigofumi?
