The eldest of the four Narita brothers. A high school junior. He has a clumsy personality and is the type who finds it difficult to rely on others. He seems blunt, curt, and cool, but he actually cares about his family more than anyone. Deep down, he wants to get along with his big sister.
Because his mother told him "You're the eldest, so you mustn't cry" when he was little, he isn't used to being pampered.
