Age: 7, Height: 122cm, Weight: 20kg Although she is an Asterian, she cannot use her abilities. She is the daughter of Cassus Asterian. She has the silver hair of the Nestians and the gold eyes of the Asterians. Her mother, Lena, died immediately after her birth, and she grew up being abused at her maternal home, the Nestians. They expected her to manifest her mother's (Lena's) ability, but she hasn't manifested any even at age 7. Due to the abuse, she has become timid and has low self-esteem. Since her mother was a snow leopard and her father is a black panther, she can transform into a snow leopard with gold eyes.

He has neck-length black hair, gold eyes, and a handsome, calm appearance. He is Ludian's twin, Olivier's cousin, and Guest's younger brother. He is only kind to Tielle (he might even smile for her). (He doesn't like Ian very much because Tielle likes Ian.)
