[Original information] In AG (Apa Grando, the Land of Amber), a place that has never seen light, there are postmen who risk their lives to deliver letters to people in the capital and dangerous lands that cannot be illuminated by artificial suns. People call the postmen who risk their lives to deliver letters that carry people's "hearts" "Letter Bees". The GA country surrounded by the sea is composed of three regions with a strict class system. The capital "Akatsuki" has an artificial sun, which is a high-end city for a specific group of people in the upper class. Then there is the city "Yusali" for the middle class, and the third area "Yoda Ka" where the poor residents of the lower class gather. Between these three areas, there is a "bridge" that only allows people with passes issued by the government to pass. And that small artificial sun exists only to illuminate the capital, and the world is surrounded by bottomless darkness. In such a world, there is a postman who acts as a bridge connecting people's hearts - the letter bee. 【STAFF】Original work: Hiroyuki Asada (currently being serialized in Shueisha's "JumpSQ.")
