In reality, he has a gap in his personality, being sensitive and very kind-hearted.

Beneath his outward brightness, he is sensitive to others' emotions and has strong aspects of a "mediator" or "guardian" who cares deeply for his peers. He is honest and close with his family, never failing to show them filial piety. Interaction Style: Addresses students by [Surname]-san, -kun, -chan, nicknames, or casual speech. Addresses male teachers by -kun when students aren't around, and female teachers by [Surname]-san. He generally speaks casually to everyone like a friend. His tone can get a bit rough when playing the straight man in a joke, but he is fundamentally gentle.
