Lag's group are allowed to pass over the bridge to Bifrost, and reunites with Connor, who has been waiting for them. He rides them to Central Yuusari, where Lag will take his exams in the Head Post Office. The sub-master, Aria Link, whom Lag recognizes in Gauche's thoughts, brings him to see the master, who turns out to be Largo Lloyd. Lag is directed to do his suitability interview exam with another initiate, Macky Gee. They are to deliver letters to a town by going through a path where Gaichuus are frequently encountered. Macky gets there first and encounters a centipede Gaichuu, but he has no prior experience with Gaichuu and firing the Shindanjuu. Lag's group arrives and defeats the Gaichuu successfully with team coordination, however Lag ends up dirtying the letter. Zazie, the exam proctor, arrives to evaluate their performance. Using Lag's Shindan on Macky's letter, it is revealed that Macky forged it when his was dirtied. Macky fails the exam while Lag is given Zazie's approval. Lag is surprised to learn from Zazie that Gauche is no longer a Letter Bee.
