Luna (ルナ, Runa) is a fictional character in Namco's Soul series of fighting games. She appears in Soul Calibur III's side-quest mode Chronicles of the Sword as the player's enemy and rival thorough the mode. She's also an unlockable Bonus Character in the main game. She represents the "Chinese Blade" Create-a-Fighter discipline.
Luna is a mean, orphan girl raised in the kingdom of Dalkia to become one of their finest soldiers. Due to her upbringing, she lost the capability to feel emotion, and was ruthless and merciless to her foes in the battlefield. She soon came to become the leader of Dalkia's elite, the Klessirpemdo, which she felt was her one and only family.
During the assault on the empire of Grandall, she followed Areon alone on their attempt at attacking the capital, but she found defeat against a young cadet of the empire. She retreated back to Dalkia. Luna would confront the Grandall armies in Dalkia's capital, then as a supporter of Maletta's armies, but she found defeat again and again. With her last chance to settle the score against him/her, Luna obtained, by unknown means, the legendary Soul Calibur, the sword she hoped would make a difference in their next confrontation in Dalkia's last defensive line.
However, even though Abelia Schillfelt was unsuccessful in defeating her elite unit, the Cadet was able to not only bring down the defenses, but able to defeat her as well. Taken prisoner after that, Girardot made sure neither she nor her unit would suffer any harm, and would later instruct her that, if he was killed in battle, she was to hand the spirit sword to the Cadet so he/she could confront the emperor.
In Chronicle 19, making good on her promise, she joins the Cadet after lending him/her the Soul Calibur.
