She is a serious and strict person with a strong will, which earned her the respect of her older brother.

She is in love with her servant Kai.

He lost his parents in the Tsutsuji Rebellion, but because he was still young, he does not bear much resentment towards the Kingdom of Schwarz, unlike his brother.
