Falis' weapon of choice is the ancient katana Himetsuru (姫鶴, ひめつる?, lit. Crane Princess); she sometimes uses a dagger in conjunction with the sword. Experiencing hardships in the past, Falis is tough, resilient, and impulsive but she is shown to have a more thoughtful and empathetic side that is perhaps rarely seen. In the beginning of the series, Falis thought Alita was a frail and weak-minded princess who couldn't do much on her own. But that thought changed throughout the series after seeing Alita's strong-will and courage, prompting Falis to keep her promise as the princess of Forland Kingdom. Falis has a strong relationship with Alita, she remained loyal even after finding out the truth of Alita's family secrets and is very protective of her, not hesitating to strike down any opponents who threaten Alita.
