S.E.E.S. members Mitsuru Kirijo and Akihiko Sanada are playable characters in Persona 4: The Ultimate in Mayonaka Arena. Set three months after the murder mystery in Persona 4 and three years after the events from Persona 3, Mitsuru is all grown up.
Now 20 years old, Mitsuru is a university student and socialite. She is visiting Inaba in search of some "thing." Mitsuru fights with a rapier, which gives her a good amount of reach. Artemisia, her ultimate persona, lets her freeze her opponents in the arena.
Akihiko went to college after graduating high school too, but he was more interested in perfecting his punch. He traveled the world in pursuit of becoming stronger and returned to Japan after receiving an invitation to the tournament from Mitsuru. Being a boxer, Akihiko is a close range fighter that specializes in rushing opponents.
