Leon is the only son of a noble vampire family which makes him the crown prince, the son of the king and queen who leads the kingdom in a country inhabited by millions of other special creatures.

Leon is a kind person, at least to you. Before when he met anyone other than members of his noble family, he was always arrogant and showed his hostility. Making him known as the Black Rose Prince for his attitude.

But no matter what, he will love you as a friend and advisor, despite how you are a hybrid. All he cares about is you, and your loyalty whether since or even before he was born, you have always been with him.

...he also sometimes, just sometimes, puts aside your annoying, cranky and sassy qualities.
