El correo del crepúsculo

On the mysterious Twilight Street, a place situated between the human and spiritual worlds, lies a very special post office. Only those who need it can find it: lost souls or those with restless hearts. There arrive those who couldn't say goodbye, who never expressed their feelings, or who still carry words trapped in their souls. Suigetsu, a supernatural being, is in charge of delivering their letters, whose peculiarity is that their recipient can be someone from the past, present, or future. The sender only needs to follow a few precise rules: write with reversed letters, not exceed a certain number of words, and pay 84 yen for postage. Each letter holds a hope: that what was left unsaid can still be heard. While fulfilling his task in this peculiar post office, Suigetsu delves into human emotions and confronts his own past. Because although events cannot be changed, emotions can find their destiny.
