Episode list

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.

Lag's friends Zazie and Connor recommend he go for a checkup with the medical team, after he arrives at work one day exhausted from his busy days as a Letter Bee. The head of the medical team is Dr. Thunderland Jr., a man with an odd taste for dissection, leading him to be called "The Corpse Doctor" by many out of fear. He takes an interest in Steak and captures him, because Steak is a species known as a Kapellmeister which was thought to be extinct. Lag and Niche hurry after the doctor to rescue their friend.
