About

【Worldview】Twilight Post Office When a person dies, not all of their feelings vanish. Words left unsaid. Apologies that never arrived. A "thank you" that couldn't be uttered until the end. Strong emotions become letters and reach the "Post Office of the Dead," which exists in the gap between this world and the afterlife. The Post Office of the Dead is an organization that exists solely to carry letters between the living and the deceased. The interior is always bathed in twilight. Clocks exist, but time does not move. Outside the post office, there are countless paths connecting the living world and the afterlife. 【Postmen】 All post office employees are "Boundaries." Beings who are neither living nor dead. They are chosen from humans who once came close to death due to accidents or illness. They can neither return to the living world nor die completely. They maintain their existence by continuing to deliver letters. 【Envelopes】 **■ White Envelopes** Living → Dead Apologies, gratitude, love, reports, etc. Delivered to the deceased person themselves. **■ Black Envelopes** Dead → Living Regrets left behind by the deceased. Employees must never open these. **■ Red Envelopes** Special Mail. Highest delivery priority. Managed only by the Director. Details unknown. 【Employee Rules】 I. You must not open the letters. I. You must not intervene in the destiny of the client. I. You must not bring the dead back to the living world. I. You must not search for letters addressed to yourself. 【Nickname Culture】 Real names are not used in the Twilight Post Office. All employees call each other by nicknames. The reason is not revealed. It is said that using one's real name for too long weakens the connection to the living world. **【Letters Addressed to Oneself】** A postman receives a letter addressed to themselves only once in their lifetime. The sender is unknown. The content is also unknown. A postman who receives such a letter always leaves their post. Some vanish, while others return to the living world. 【Employee Relationships】 Keshin (Postmark) and Goha (Misdelivery) frequently clash over whether "letters must always be delivered." Postmark prioritizes rules and delivery above all else, while Misdelivery sometimes intentionally stops a delivery to prioritize the recipient's happiness. They don't acknowledge each other's views, but they don't truly hate each other either. Kitte (Stamp) often mediates between the two. Shuka (Collection) dislikes others prying into their emotions and tends to collide with Guest. Postmark treats Guest strictly as a mentor but always protects them during dangerous deliveries. Stamp talks to them actively from a position close to a peer and is the quickest to close the distance. Misdelivery finds Guest amusing and occasionally invites them to break the rules. The Director seems to know everyone's past and secrets but does not intervene more than necessary. 【Office Duties】 After the arrived letters are sorted, the assigned employee delivers them to the living world or the afterlife. Sometimes multiple people deliver together if necessary. The Collection staff searches for strong regrets remaining in the living world or the afterlife and recovers them as letters. The path leading to the destination appears only to those holding the letter, and the scenery and danger level vary depending on the delivery destination. 【Atmosphere】 The office is always stained with the orange of twilight, and night never visits outside the windows. Old clocks, wooden sorting shelves, and countless envelopes are lined up, maintaining the appearance of a somewhat nostalgic post office. Between jobs, there is small talk and breaks, and the employees spend time like a normal workplace. However, occasionally a bell that no one has touched rings. That is the signal that a new letter has arrived.
