Arcana
Persona 3 makes use of the thirteen Major Arcana of tarot cards. Each Persona user in the game represents a different arcana, which is in turn symbolic of their personality. Due to the differing social links between the male and female protagonist, Akihiko has two different arcana depending on the route being played. If the player choses the male protagonist, Akihiko is the Emperor. If playing the female route, his arcana switches to the Star.
The Emperor

The Emperor can arguably be connected to Akihiko's personality in a variety of ways. For one, he is certainly disciplined and experienced compared to most of the other members. While he is not the leader of SEES, he does show leadership qualities as well. The importance of putting logic over emotions is very representative of Akihiko's character. When Polydeuces gives rise to Caesar, for example, Akihiko is initially overwhelmed with grief and confusion over Shinjiro's death/coma. However, when he pulls himself together and realizes he needs to push his feelings aside and focus on what lies ahead, he is able to formulate his resolve for fighting. If he had let his emotions get the best of him, he certainly would have become immobilized. Did he want to let his mind triumph over the heart? Probably not since his grief was strong. It was just the most effective way to overcome a difficult situation. While I would hardly say Akihiko is a control freak, I still feel the last part of the description above fits his character. He tries very hard to keep others at a distance in order to control how important they become to him. He also desperately wants to have control of his strength development and tries to keep tight control over his feelings around Miki's death. He later realizes, though, trying to control all of those things ultimately does not benefit him or others--just like the Emperor's reminder.
The Star

Connections can be drawn between Akihiko's character and the Emperor. The Star, however, I feel is more representative of Akihiko's relationship with the female protagonist. This makes sense, if you think about it, as Akihiko only becomes the Star for the purpose of a social link with the female protagonist. He lets himself become vulnerable around her while talking about Miki and therefore trust is built. Through their relationship, Akihiko slowly begins to see the light at the end of the tunnel. He's carried sadness and guilt for so long but he can now see hope he can move past such feelings. He comes to terms with the fact he had only been pretending to get over Miki's death because he didn't want to face what happened. He reaches clarity regarding his feelings for her death and for the protagonist herself. By spending time with the protagonist, Akihiko also resolves to protect the things important to him rather than not allowing things to become important. In that sense, he becomes more positive, confident and has a solid goal to move towards. Lastly, I would argue that by finding a new resolve through their time spent together, Akihiko is regenerated as a character. He is able to make peace with his demons and see the world in a new way.
