Plot
The story takes place in AmberGround, a land of perpetual night partially illuminated by an artificial sun. Lag Seeing, who used to work for the Bee Hive delivery service, is appointed as a Letter Bee, traveling with his Dingo (Bee's bodyguards), Niche, and her pet, Steak, to deliver letters and packages while avoiding the Gaichuu—giant armored insects who feed on the "heart" within letters and packages. When he was a child, his mother was kidnapped by men from AmberGround's capital, Akatsuki, and he was sent as a "delivery" to his aunt thanks to Gauche Suede, whom he began to idolize and who was his inspiration for becoming a Letter Bee.
