A new band of villains has appeared with their shade partners, with plans to steal an ancient artifact, being donated to the museum by the well respected Yamada family. During the commotion, the bandits take Rai's little sister hostage, with the intent of using her as both a shield and means of a bribe. The owner of the airship and the museum is Akira's father. Akira is also there in attendance with Danton. However, whilst all this is taking place below, Rai continues to force Danton into battle on top of the airship. With bombs placed all around the ship, some unwilling team work may be required, in order to prevent everything from crashing down.
