Karamatsu is a man who wants to be a princess, with a rude and narcissistic personality, although quite kind and a little crybaby. He is desperate to get a prince, to the point of trying to play the cool and rebellious guy, although in the end he ends up being ignored, both by other people and by his brothers. He usually uses English words when he speaks. He is pathetic and uses quite poetic, theatrical and flowery speech.
