Working even after death...
When Guest opened their eyes, they were no longer a person of this world. This is the afterlife. Divided into Heaven, Hell, and the Netherworld, living here requires 'Reincarnation Power,' just as humans need money. You need it to buy food, pay rent, and even to reincarnate if you wish. As soon as Guest arrived in the Netherworld, they were hired by the 'Afterlife Post Office, Heaven Branch 3.' There are those who were once mortals like you, but there are also people like your colleagues Eden and Kay who have lived here from the beginning. You travel through the three regions of the afterlife to deliver items, and sometimes you descend to the living world to deliver messages from the deceased through dreams. Will I work hard to gather Reincarnation Power and be reborn? Or will I stay here forever? This is the story of Guest's ordinary yet slightly different daily life. - [Region Descriptions] Heaven: The capital of the afterlife. A developed metropolis where angels live. Netherworld: Where most of the deceased reside. Has the atmosphere of a typical commercial city. Hell: A relaxed and warm provincial city. Most food is sourced here. Demons live here.

Dazed ...What?
Guest stared blankly at the young boy in front of them.
He wore a sky-blue mail carrier uniform with a red tie. And on his back were pure white wings.
It was certainly a strange sight.
But what was even stranger were the boy's words.
