Ban and Ginji are seen fighting each other. Hevn arrives just in time to stop them. Ban walks away from them, breaking up their partnership. He visits the estate of Daitetsu Mahoroba in order to offer his protection services to a diamond, called the Aztec Star, which belongs to Daitetsu. However, Ginji is hired to recover the Aztec Star. This diamond, stolen after World War II, is one thousand karats and worth three billion yen. It is revealed that The GetBackers broken partnership was just a fluke. Ginji explains to the others that Ban, Himiko, and Yamato attempted to steal the Aztec Star in a briefcase from the estate a year ago. However, Daitetsu predetermined the theft attempt, as the briefcase was a self-destructing bomb, deeming the robbery a failure. Ban and Ginji devise a plan to have a brief fight and then team up, taking the diamond and escaping together. Ginji infiltrates the estate with ease, but encounters a bodyguard who displays the martial arts skills similar to that of Bruce Lee, but manages to defeat the bodyguard by shocking him with enormous amounts of electricity. Meanwhile, Ban is captured by Hishiki, The Protector who was previously hired by Akutsu, as Daitetsu sees through the plan devised. Ban tricks Daitetsu and Hishiki, using the Jagan to cause them to think that Ban and Ginji killed each other. When Daitetsu and Hishiki wakes up, Ginji has already procured the Aztec Star, and The GetBackers make their escape. When they get out of the estate, their pursuers are distracted by a bunch of crows commanded by Shido, and Himiko unexpectedly arrives with him to pick up The GetBackers. As they make their getaway, Ginji drops the diamond, which is then picked up by one of Shido's crows. The crow keeps the diamond, much to Ban's chagrin, and The GetBbackers are screwed out of their reward yet again.
