Farewell, My Beloved.Ban and Ginji are asked to recover a stolen government object. They record a sighting of a strange phenomenon, and they present it to Hevn the following day. Hevn sees a familiar person in the footage, and then cancels the mission for Ban and Ginji, giving them compensation for the cancellation. Hevn flashes back to when she was working in a research facility. The research facility was attacked by an army of commandos, and Eiji, her research partner, was shot in the process. In another flashback, Eiji discusses an alloy, which can be used to make methods of transportation more reliable. It can also make building more durable in structure, and can make prosthetic arms and legs more flexible and agile. So it seems that Hevn takes on the assignment, to retrieve the alloy, which is the stolen governmental object. She infiltrates the commando ship, is faced by an army of commandos and she surrenders. She is taken to Eiji, and eventually recognized. During the battle, Ban and Ginji are revealed disguised as commandos; the commandos are defeated. The leader runs away, and the three chase Eiji. When he is found, they attack him. Ginji's lightning and Ban's grip are rendered useless, as it is revealed that his clothes contain the alloy. She is surprised that Eiji survived the commando attack from years ago. He reveals that he is an agent, assigned to steal the alloy. He revealed that he got close to Hevn to make achieve his plan. Feeling deceived, Hevn prepared to snipe Eiji. However, he offers to go with her to restart their lives. He shows his bullet wounds from the commando attack to prove that he cares for her. Ban and Ginji leave Hevn and Eiji alone. The next day, at the Honky Tonk cafe, Ban and Ginji wonder the whereabouts of Hevn and Eiji. Ironically, Hevn walks in and offers them a new assignment.
