Mitsuru

Mitsuru has waist-length red hair (the hue of her hair can sometimes appear vivid red or dark red) that has bangs covering the left side of her face with a wavy mid-back length hair strand resting on her left shoulder and her eyes are brown, although they have sometimes been portrayed with hints of red.

At school and in Tartarus, she wears the Gekkoukan High uniform with personal effects: no jacket, a white blouse (long sleeve in winter and short puffy-sleeve in summer), a black skirt that goes above her knees, and black knee-high high-heeled boots. On the weekends and days off, she wears a short black peacoat, a white scarf, and white pants, along with her black boots. In the summer, however, she wears a white sleeveless turtleneck shirt and black pants with a belt. As with the rest of SEES, Mitsuru wears a swimsuit during the excursion at Yakushima. She is seen wearing a kimono at numerous appropriate occasions. 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. Her Persona Arcana is the 03.0Empress, which fits with the "motherly/older sisterly" role she plays in the group.

Mitsuru has a streak of strict conduct. Per formal 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. For example, when the female protagonist is elected leader and Junpei Iori is annoyed because "he's the only guy in the group," Mitsuru sternly tells him that "Whether one is a man or woman doesn't factor into it. The responsibility falls to those who have the gift. And let me add, if you ever say or do anything to condescend to her because she's a woman...". 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. It is noted by her father that she has difficulty trusting others, and at one point he tells her that she can only do so much on her own and reminds her of the Kirijo Group's guiding principle, "Two in harmony surpasses one in perfection," which Mitsuru takes to heart. She also secretly likes to read teenage fashion and is interested in it as seen in the video recordings in FES and Portable. However, she doesn't know much about it unless she hears Yukari talk about it. In the same video recordings, she tends to break habits that she wouldn't normally do at her home like walk around with just a towel in her room.
