Michel Volban de Cabelle—the figurehead of the People's Army. She is actually the sister of the real Michel Volban who has disappeared in the war with Vetti. She had her own back scarred with a X-shaped mark in order to imitate her brother's scar which was flashbacked after being revealed as a woman to Cleo's crew. A man resembling her brother was part of the attack force that infiltrated the glass battleship. This man was emotionless, brainwashed and was constantly attacking Michel but she still believed he was her brother. In the end, when Cleo and her brother was about to be sucked out into the depths of space, she chose to save Cleo and said that man was no brother of hers. At the end of the episode, it was shown that the man was her real brother Michel with an X-shaped scar of his back. Michel's personality is evident because of her past. She had little contact with her deceased mother -her mother dying months after she was born- and her father being home rarely. She learned to fight from her brother, who had become a major role model in her life. She loved fencing and wished to be like her brother—which may explain her tom-boyish attitude. After her father had seen her fencing with her brother, and seeing that she surpassed him, she was ordered to be more like a lady of a royal house. After that incident, she vowed to herself that she would be and become a proper lady. But, after her father's death, and her brother's death during the major battle in the beginning of the series, she renounces her identity and becomes her brother in order to save the People's Army destruction. In order to do that though, she chooses to truly become her brother, by gaining a X-shaped scar on her back like her brother had once gotten from a battle with Vetti in a tournament, and also renouncing her real name, which is Racine Blance. All the effort to act as "Michel" was due to her love for him which was beyond sibling love. In later episodes, she falls in love with Cleo Corbeille.
He takes on Michel Volban de Cabelle, the figurehead of the People's Army and uses Michel as bait to lure out Cleo. He is the Holy Emperor who wanted to unite the galaxy in order to be able to obtain the technology of the battleship that can transcend space and time. He uses whatever means, even marriage to Rachel, the daughter of the Pope who initially despises him. He also has an innate dislike for Cleo who he sees as a rival for the throne and a fascination of Michel who initially was his best rival. Vetti revealed that he wants to obtain the technology because he has an incurable disease and may die soon. Vetti has Heterochromia, where he has one gold eye color and one is brown.

Cleo Aiolos Corbeille de Veil—a supposed descendant of the royal family who has gathered a crew of people who are wanted all over the galaxy for their special abilities; they follow Cleo and later winds up following Michel in order to save Cleo. Cleo's personality is "like the wind", to his comrades, it's unpredictable where his next destination will be or which way he wavers. His rough, seemingly, uncaring personality was shown bluntly to Michel and his followers when they first meet after being saved by him. At first- to Michel's servants- he seems more like a pirate than a savior: only caring about material things than anything or anyone else as he wishes for payment for saving Michel. As the story-line progresses, Cleo shows more and more defiance towards the idea of fighting with the People's Army while with them. It is not until the first big battle begins that, where his newly found rival, Vetti is to be watching. In later episodes, he falls in love with Michel Volban (Racine Blanch).
