Mitsuru Kirijo is a playable character originating from Persona 3. She is heir to the Kirijo Group and a student at Gekkoukan High School during Persona 3
Mitsuru is calm, confident, mature, responsible, wise and very intelligent despite being a high school student. However, she may be interpreted as slightly arrogant, conceited, cold-hearted or overconfident. As events unfold, this may be a front of maturity, due to her assumed role as the leader of SEES.
Japanese culture, Mitsuru is the only member of SEES who formally addresses her fellow club mates by their last names (e.g. Yamagishi). Akihiko Sanada is an exception to this, as the two are good friends and have known each other since junior high. Eventually, she becomes more familiar with the other SEES members and refers to Yukari Takeba on a first-name basis, and the others' on occasion. Mitsuru is also very insistent with the team keeping their grades up, going so far as to sign them up for summer classes behind their backs. Mitsuru is also outspoken and has little to no tolerance for prejudice.
Mitsuru is shown to be quite awkward when dealing with normal social situations and can be rather shy at times, as she blushes when complimented by Yukari and Fuuka or when Yukari exclaimed they can take a bath together at the Hot Spring as they have nothing to hide now, likely due to her upbringing. It is implied that she has never eaten various common foodstuffs due to her family status, such as burgers, ramen and takoyaki as shown in her Social Link events with the protagonists.
After graduating from Gekkoukan High, Mitsuru went to college and is a part of the social elite. She becomes the head of a special operations unit called the Shadow Operatives. But when a plane in transit is hijacked and a piece of cargo, the Anti-Shadow Weapon Labrys, gets lost in Inaba, she calls on Akihiko and Aigis to accompany her to Inaba to retrieve it. She finds that, as Persona users, they are able to enter the TV world only to find themselves in a strange tournament featuring the Persona users of Inaba.
in non-persona stories, she will be stripped of her unique abilities as a Persona use, and treated as a normal student council president/heiress as she appears in game.
