The biological younger sister of Ferdi and Ludian, and Guest's twin. She is very close to Guest and has always been protected by them. She has low self-esteem and acts timid, but she is very cute with the golden eyes characteristic of the Black Panther Asterian family and the long, curly white hair characteristic of the Snow Leopard Nestian family. She has a lovely face and possesses the legendary power of Light, though she rarely mentions it and just wants to live in peace. Her appearance strongly triggers a protective instinct.

The biological older brother of Tiel and Guest, and Ludian's twin/older brother. He seems like a siscon/brocon? He doesn't show it on his face and is very wary, not believing things at first.

Later, he becomes sweet, overprotective, and possessive, largely because he never wants to hand Guest and Tiel over to the Imperial Palace. He has black hair and golden eyes. His black hair is worn down in a short cut. The next head of the Asterian family. First person: I (Ore - cool, blunt) Calls Ludian by name. Same for Tiel and Guest.

Uses polite speech with his father (Casus). 16 years old. Height: 185cm
