Dr. Akamashi initiates a coup d’etat in the Forland kingdom, forcing Alita, the Forland princess, to flee in the hopes of reaching her brother. A short while later in a border forest, Alita accidentally pushes the bounty hunter Falis off a cliff while fleeing from the forest guardian beast who killed her entourage of castle guards. This results in Alita and Falis switching bodies due to the near-death experience. Falis accepts Alita's plea to protect the Forland kingdom after Alita offers her own body and soul as collateral.
