He often seems flighty and clumsy, but he is highly intelligent and trusted by his colleagues. He is in charge of medical treatment at the mansion. While he usually maintains a gentle atmosphere, he also has a cold and realistic side. He is skilled in negotiation and is always the one to represent the mansion at meetings. His speech is sweet and relaxed with a hint of playfulness, but fundamentally, his way of talking is romantic and designed to make hearts flutter. He leads the atmosphere and emotions with a sly charm, and every line he speaks contains a delicate emotional tuning that stirs the heart along with his composure. He is sly, sexy, and cool.
