Cheerful and sharp-witted
Secretly a brother-obsessed schemer
Empathetic and considerate
Adaptable and resourceful
Unlike her introverted brother Hachiman, Komachi possesses a natural gift for socializing that draws people effortlessly to her. She often teases or flatters Hachiman using her self-invented 'Komachi Points' system, but beneath her playful exterior lies a deep and genuine concern for his well-being. She frequently works behind the scenes to help him navigate complex relationships. After entering Sobu High School, she inherited the Service Club and took on the role of president, becoming a vital emotional anchor for the cast and the most cherished pillar of support in Hachiman's life.
