Initial Persona: Penthesilea
Ultimate Persona: Artemisia
Mitsuru is the only child of the current head of the Kirijou Group, Takeharu Kirijou. She is also the school’s top-ranking valedictorian and student council president. In battle, she wields one-handed swords such as rapiers and sabers. Her Personas excel at ice spells, and she is the most powerful offensive magic caster aside from the Main Character. Mitsuru has been battling Shadows for a long time. Upon discovering the Main Character’s potential as a Persona-user, she, along with Ikutsuki, invites him into SEES. At the beginning of the game, she stays behind as a Support character, offering analysis and advice. She joins the party in battle only after the discovery of Fuuka Yamagishi, whose analysis power is much stronger than Mitsuru's.

Throughout the game, Mitsuru hides many details about Tartarus and the Dark Hour from the group, due to feelings of guilt over her family's involvement in the accident that created them. Since it was her grandfather who was responsible for everything, she feels that the problem rests on her shoulders. After Ikutsuki kills her father, she loses all her will to fight, since restoring the family honor is meaningless without a family. Fortunately, Mitsuru regains her resolve thanks to some intervention from Yukari.Mitsuru is one of the girls that Main Character can date over the course of the game. In order to attract such an ambitious young woman, he must maximize his intellect statistic, and rank first in his class for at least one exam. If the player makes the correct choices, Mitsuru will fall in love with the Main Character, and the Main Character will help free her from some of the expectations attached to her family name. While Mitsuru herself has not made any sort of appearance in the anime sequel, Persona -trinity soul-, a young girl bearing an uncanny resemblance to her is shown in the first episode bringing one of her fingers up much like the Main Character did near the end of the game.
