Each episode is a stranger's last words arriving too late. Fumika delivers them anyway, and you watch the living realize what they should have said while the dead already know they never will. The show understands that some letters change nothing, some destroy everything, and most do both at once. By the final episodes, you stop asking what Fumika is and start asking why she's the only one who cares enough to deliver mail nobody wanted to receive.
Fumika delivers letters from the dead to the living. These shigofumi carry final words that the deceased could never speak in life: love, longing, resentment, regret, sometimes words of no importance at all. As a mail carrier for the afterlife, she crosses between the world of the living and the world of the dead with her talking staff Kanaka, making sure each letter reaches its recipient even when that person would rather not read it. But Fumika herself is a mystery. Carriers are dead people who keep the look they had just before dying, yet she is still growing older, and little is known of who she was before. When an old classmate recognizes her during a delivery, he begins digging into why she vanished from school and why she now carries messages from the dead. Each delivery exposes the tragedies and hidden secrets of the people involved, living and dead alike, in a dark psychological drama with supernatural and thriller elements.
