Falis

ファリス

Falis is one of the world's strongest and most notorious bounty hunters, even credited with slaying a dragon. While operating near the border of the Forland Kingdom, Princess Alita encounters her, and the two accidentally swap bodies. Now trapped in Alita's body, Falis strikes a deal with Alita to take on her identity and defend her kingdom. Falis' weapon of choice is the ancient katana Himetsuru (姫鶴, ひめつる, Himetsuru, lit. Crane Princess); she sometimes uses a dagger in conjunction with the sword.
