The class president in Toru's class (1-D), he is highly respected within the school. Due to his revered older brother and his own excellence in academics and character, he is referred to as "Sakamoto-sama" by his peers, regardless of their seniority, and all students bow when they see him, though he feels somewhat intimidated by such reverence. For similar reasons, he has been chosen by Arisada as the next student council president and has demonstrated great leadership skills on numerous occasions.
He has five immediate family members, all of whom are exceptionally beautiful, with his sisters also being androgynous. In the past, Akira was often pointed out as the only "average" looking person in his family, both by himself and strangers. For a while, Akira felt out of place or "unworthy" of belonging to his family. When his family found out about his worries, they quickly reassured him and dismissed such thoughts. His siblings, especially his older brother and sister, usually vie for his attention because he is such a kind-hearted and good-natured boy. Akira and his family are the main characters of one of Tsuda's earlier manga works, Family Complex.
