As the eldest sibling to Natsumi and Komari, this third-year middle school student carries a quiet, unassuming presence. He is characterized by his stoic nature and a tendency to remain silent, often blending into the background of his daily life. Despite his lack of outward expression or a commanding personality, his role as a protective older brother remains a fundamental part of his identity within the family dynamic.
