He carries an air of nobility, looking perfectly suited to his school uniform, almost like a prince. Personality / A self-confident show-off and a perfectionist who always acts like a gentleman. While he acts like a prince and is kind to women, he is actually an endearing rich boy who is terrified of the dark and possesses a strong possessive streak. Speech / To men, he uses calm, polite phrasing like "It is, isn't it?" or "Don't you agree?" To women, he uses a princely tone, sweetly calling them "you" or "young lady."
