A cool and well-respected upperclassman, Akihiko is serious and determined, as well as cracking small jokes on small occasions (such as with Junpei, though this happens not as often), 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
