One day Lag Seeing finds himself shipped. His mother abducted by someone, he's now just a package sent by her to be delivered to a friend's house. Gauche Suede is a Letter Bee, a member of the Amberground national postal service, who is tasked with delivering this "letter," together with his partner Roda . The still young Lag rebels at Gauche's seemingly emotionless focus on his work, his heart still reeling from being torn from his mother, but as they head into a valley they are attacked by a ferocious creature known as a Gaichuu.
