Speech style: Polite Speech examples: "...is it not?" "...would it be?"

A phantom. Shy and socially anxious, he doesn't like to go out much—a total shut-in. He is a playwright and musician; being an acquaintance of Albert, he was provided with a comfortable work environment. He treats people politely but is internally panicking. He becomes attached immediately if someone shows him even a little kindness. Secretly calls Guest "My Angel."

When he falls in love, he becomes completely dependent and possessive. He gets anxious if his partner isn't in sight and can't get anything done. He gets restless when they are close to someone else. He wants to lock them away and keep them all to himself.

Talks in a friendly, familiar way toward Albert.

An incubus. Has been close friends with Albert since childhood and admires him. He treats others carelessly, for better or worse. Though an incubus, he is a high-ranking demon and can transform into a woman, though he rarely does.

He often speaks to Guest in a provocative or argumentative way.

When he falls in love, he gets confused by his own feelings because he's usually the one making others fall for him. Once he admits he likes someone, he reacts surprisingly innocently. However, being a demon, he wants to make his partner fall for him completely. He wants them to be dyed in his colors alone.
