The class president in Toru's class (1-D), he is a highly respected member of the school: due to his much-revered older brother and his own excellence in both academic performance and character, he is referred to as "Sakamoto-sama" by his peers regardless of their seniorities, and all students bow when they see him, though he feels somewhat intimidated by such reverence. For pretty much the same reasons, he has been hand-picked by Arisada as the next in line for the student council president and has on quite a number of occasions shown great leadership skills.
He has five immediate family members, all of whom are amazingly beautiful (and, in his sisters' case, androgynous as well). In the past, Akira had often been pointed out as the only "average" looking person in his family by both 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 ideas. His siblings (especially his older brother and older sister) usually fight for his attention, since their brother 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.
