Lag and Niche begin their first delivery. On their way, they meet a fellow Bee named Moc Sullivan, who thinks that Lag is not fit for the job. He feels there's no need to concern themselves with the content inside the letters, all they do is just deliver them. Lag and Niche arrive at the sender's house, a down-and-out writer named Vincent Alcott. He writes fictional events of his day-to-day life in his letter to his mother. Lag objects this kind of behaviour but can't do anything about it. Crossing a perilous bridge to deliver the letter, Lag, Niche and an old woman encounter a Gaichuu which attempts to destroy the bridge. After Lag and Niche defeat it, the shindan hits the letter, revealing Vincent's memories to the woman Louise, who really is his mother. However, Louise knows that her son writes these kind of letters to her, and hopes that he will one day make his dreams a reality and come back home with pride. On their way back, Niche shows Lag a letter hidden inside one of Vincent's books that Steak ate. Realizing this is the letter that contain Vincent's true feelings, Lag decides to return it to its owner.
