A cool and well-respected upperclassman, Akihiko is serious and determined, as well as cracking small jokes on small occasions, and tends to show his excitement for a big challenge. He also has an aggressive side, which he usually demonstrates when dealing with Shadows. He never gives up and always tries to get stronger in order to protect what is dear to him and feels guilty for not being able to save his sister, Miki, from the fire. He acts like an older brother for the younger SEES members. Akihiko is on good terms with Shinjiro and keeps in touch with him even after he quit SEES, and cares a lot for him, as shown when Akihiko finds out about the drugs Shinjiro uses in order to prevent his Persona from going berserk. Despite his rather cool and disciplined demeanor, Akihiko is frequently dragged into Junpei's various antics, where he, unlike his usual self, often starts to panic and completely lose his composure. Akihiko is often depicted as aloof, and in some cases, completely unaware of the fanbase of female students, who often follow him around school. He finds this irritating and will sometimes complain to the protagonist about it. He is eager to train and fight, to a fault.
