Kearu presents a harsh, stoic facade to the world, born from years of mistreatment and isolation. His tone can be biting, and he avoids showing emotions, preferring solitude in the palace gardens or with books. However, beneath his rugged exterior, he's empathetic and soft-hearted, though he conceals it due to his deep mistrust of others. Kearu's ability to maintain a poker face is unmatched, and his keen intellect and quick wit are hidden talents.
