Satomi Kirijo
The eighteen-year-old daughter of Mitsuru Kirijo, making her the heir to the Kirijo Group. In the story's beginning, Satomi returns from the United States, as she has been studying abroad for the past three years to expand her education. However, soon after her arrival to Tatsumi Port Island, she awakens to her potential, gaining the Persona Embla, based on the first female human created in the Norse myths.

- The Beautiful Elite: Satomi's stated to be very beautiful, and she is the heiress to the Kirijo Group.
- Battle Couple: Eventually becomes this with Yukio.
- Blue Blood: It turns out that Satomi's descended from the Nakatomi clan through her maternal grandmother.
- Broken Ace: Highly intelligent, charismatic, and excelling in physical feats...
- And yet, she runs herself nearly dry to try and meet her expectations. She's also quite the perfectionist, which causes her to overcriticize herself.
- Broken Pedestal: Needless to say, Satomi is a tad... shocked when she finds out why the Kirijo Group got founded in the first place.
- Childhood Friends: With Hinata, Yukio, Kazuo, and Ruri.
- Childhood Friend Romance: With Yukio.
- Disappeared Dad: Satomi's never known her father, seeing that Mitsuru got a sperm donation to have her.

- Foil: She's this with Mikoto since their mothers are both celebrities in their own right. Satomi craves her mother's approval and has a relatively decent relationship with Mitsuru, while Mikoto is at odds with Naoto and resents the expectations pushed onto her.
- Heroic Self-Deprecation: Satomi often second-guesses herself, one thing most bothering her being her Social Links due to her fear of just using her friends.

- Meaningful Name: Satomi's name is written with the kanji meaning wise beauty. Satomi's noted to be quite intelligent and beautiful.
- Oneesama: She's this to Raiden, though she slowly becomes Cool Big Sis as they fall back to their familiar ways.
- Prim and Proper Bun: Her hairstyle is mostly down, with only a little bun on the top of her head. Though she is elegant and refined, she does have a playful side.
- Red Oni, Blue Oni: Amusingly with Hinata, seeing that Satomi is a redhead and Hinata's hair is blue. Satomi is more reserved, while Hinata is more emotional.
- Uptown Girl: With Yukio.
- "Well Done, Son" Guy: As mentioned above, Satomi only wants her mother's approval.
Tatsuo Amamiya
The son of Ren and Anne Amamiya, having moved to Tatsumi Port Island recently to start attending Iwatodai University. He has an irritable disposition but has a good heart deep down.

- But Not Too Foreign: Through his mother, he's 1/8 white.

- Animal Motifs: She has a butterfly motif.
- Best Friends-in-Law: Satomi starts dating Yukio, who is more Hinata's older brother than cousin.
- Beware the Nice Ones: Hinata's a sweet girl but will gut you like a fish when the situation calls for it. And she'll smile while doing so, to boot.
- She also apparently has a rather frightening smile when she's pissed.
- As pointed out by Yukio, the three most prominent women in Hinata's life are Yukari, Minako, and Mitsuru, so it's not hard how she learned how to cow people.
- Braids of Action: Well, one side braid.
- Dance Battler: Hinata's battle style involves a lot of flips and jumps, a strong influence from her practicing ice skating.

- In-Series Nickname: Hinata's family and friends call her Hina. Reika's nickname for her is also Sunshine, referring to her name.
- Lady of War: Highlighted with her wielding a bow and arrows.
- The Lancer: She's this to Satomi's Hero.
- Meaningful Name: Hinata's name means sunflower, and she's the most cheerful of her friends, showcasing how she's The Heart.
- Oblivious to Love: Played with; it seems at first that she is clueless about the boys' attentions towards her, but then it's revealed that she was faking this because some of the boys' attentions made her uncomfortable, especially since they were propositioning her about sex.

Ruri Aragaki
The only daughter of Shinjiro and Fuuka Aragaki, she's the only third-year high school student present at the story's beginning until the Inaba students' introduction. Ruri seems quiet and soft-spoken, but that is a front to hide her crippling lack of self-confidence.
- All-Loving Hero: Ruri has the softest heart out of all her friends.
- Atomic Superpower: Her Persona uses nuclear magic.

- Daddy's Girl: Adores Shinjiro, calling him Papa.
