Numerous incidents of Reverse marauders attacking Bees and stealing their letters come to a head, with Largo writing reports to the inspectors from the capital, Hazle Valentine and Caribs Garrard, who has arrived in Yuusari. Moc Sullivan comes in with news of being ambushed and losing his letters in a ravine. When Lag offers to help retrieve the letters, Hazle and Carib stop the Bees as they have no qualification to deal with Reverse, and they also suspect a leak within the Bee Hive. However, Lag, Niche and Steak stow themselves away on the inspectors' carriage. Upon discovering Lag has followed them, the inspectors decide to let him and the others follow them to the ravine. Finding the letters scattered around, Lag offers to help collect the letters when Carib tells him he will reveal what he knows about Gauche. After Lag and Niche are distracted by Carib and Hazle respectively, Carib uses a catalysing agent that resonates with the hearts in the letters to attract a gaichuu. After Lag and Niche destroy the gaichuu, Lag inadvertently finds a letter regarding the leader of Reverse, Lawrence. He reveals he is a failed man-made spirit created by an experiment sanctioned by the government and stirs up support from the populace. Gauche/Noir is confirmed to be working for Reverse. Although disappointed, Lag remains firm in delivering letters for the people. Later, Lawrence listens to the results of the experiment to attract gaichuu from the inspectors, who are revealed to be working for Reverse. Lawrence decides the time has come for Reverse to make their next move and sends Noir and Roda to the north.
