class defeat Class 2-B in Volume 1. Despite being an idiot, Akihisa is generally polite and well mannered among his friends. Yuuji is Akihisa’s closest guy friend and confidant, though they also share a rivalry with one another and tend to play tricks on each other. Akihisa's parents are on long-term overseas work assignments and send money back regularly. However, he always spends this money on the latest games, and as a result, he has to live on merely salt, sugar, and water. In the anime, he is depicted to survive on a sub-divided piece of cup noodles which can be as small as 1/64 of the entire piece.

Akihisa is also the class ambassador of Class 2-F, appointed by Yūji. Akihisa also has excellent cooking skills, as a result of having to fend for himself because he lives alone, and is good at housework. His favorite dish to make and eat is paella. After the tournament in Volume 2, Akihisa acquired the platinum bracelet that lets him perform dual summons, allowing him to have two Shōkanjū in a battle. Since Akira started living with Akihisa, his grades have seen a significant improvement from what they were before since he has more incentive to study. His Shōkanjū wears a school uniform and wields a bokken. During the ESB field error, his Shōkanjū was unaffected, but it multiplied enough to literally flow out
