Voice Actor: Liam O'Brien (https://youtu.be/nJ1PUE4T_2E)

A student at Gekkoukan High School and a member of the Specialized Extracurricular Execution Squad.

A cool and well-respected upperclassman, he is serious and determined, as well as cracking small jokes on small occasions. Of all members of the group, he is the most prone to sarcasm, one instance being if the protagonist talks to him while he and Junpei are taking a break from studying for first semester midterms, stating that Junpei isn't studying for his exams as Mitsuru told everyone to go back to their routines. He tends to show his excitement for a big challenge, something that eventually rubs off on Junpei. He is eager to train and fight, often to a fault. Early on in the game, when he is injured due to a fight with one of the twelve full moon Shadows, he will repeatedly express interest in fighting despite being unable to. This draws criticism from Mitsuru, who views Akihiko's eagerness to fight as if he treats their work as a game. At one point, Yukari even accuses him of caring more about having a good fight than doing the right thing. However, he is a kind young man who will go out of his way to help someone, which is shown when he was willing to take any chance to save Fuuka from Tartarus despite having never met her before, even after Junpei and Yukari pointed out that she had been there for ten days (or ten hours from her perspective) and most likely couldn't have survived.
