A money-obsessed fairy who charges out the nose for healing springs. Gets much more character development in the second game.
- Adam Smith Hates Your Guts
- Bare Your Midriff: Only really noticeable in her official artwork.
- The Exile: Exiled from the fairy kingdom until she does enough good deeds.
- Cultural Translation: An indirect victim of this thanks to the original localization translating yen to dollars. As a result, her "gouge your pocketbook" tendencies for utilizing the healing spring aren't nearly as severe in gameplay terms.
- Healing Spring: Owns one.
- Money Fetish: She's obsessed with money, and will charge high prices for her healing services.
- Winged Humanoid
Yamaoka, known as Alfred in the English localization, is the butler for Kei Nanjo. When told by his teacher to go to the hospital, Kei meets his butler Yamaoka at the school gate, who offers to chauffeur everyone via the Nanjo family's limousine. Kei refuses, preferring to walk with his friends instead. Yamaoka yields, but secretly follows Kei to the hospital.
When the ICU where Maki Sonomura is being treated vanishes following a small earthquake, the group flees to the lobby downstairs. Kei is shocked to find Yamaoka sprawled on the hospital lobby floor, mortally wounded by a demon attack. Yamaoka knows that he is not long for this world, and his dying wish is that Kei would become a great man someday even after he has gone. Late in the game, he returns as the ultimate Persona for Kei.
- Ascend to a Higher Plane of Existence: After his death, he is resurrected as Nanjo's ultimate Persona.
- Came Back Strong: As Nanjo's Ultimate Persona.
- Guardian Entity: Even in death, he protects his young master.
- Holy Halo: As a Persona.
- Hover Board: As a Persona.
- Obi-Wan Moment: Kei takes Yamaoka's last words to heart, as seen in later games. In fact, the scene in which this happens pretty much, name changes and all, survives intact in the localization in both impact and meaning.
- Parental Substitute: Kei's parents are always away on business. He is closer to Yamaoka than he is with his own father.
- Sacrificial Lamb: He has the distinction of being the first character to die onscreen in the Persona franchise, establishing the stakes of the game as well as Nanjo's own Character Development.
- Shout-Out: A butler named Alfred taking care of a rich but lonely young man who ends up saving the world. Sounds familiar?
- Stoic Spectacles: Following his death, they're switched out for a Cool Visor.
- Undying Loyalty: Even death couldn't stop him from protecting Nanjo.
- We Hardly Knew Ye: Other than his Undying Loyalty to Nanjo and being his Parental Substitute, we don't know much about him before he dies.
Another strange little girl in white who appeared along with Mai. She uses her Compact Half to alter her side of the town, and hides in the Gingerbread House. In the Bad Ending Route, she first attacks the party with a Monster Teddy Bear, then she makes Aki and Maki disappear into the virtual reality.
She is later revealed to be Maki's ego and represents her innocence.
- Bears Are Bad News: In this case, a Monster Teddy Bear named Mr.Bear.
- Children Are Innocent: Unlike Aki, Mai is benevolent and means no harm to the party unless threatened. It turns out she also represents Maki's innocence as a child.
- A Dog Named "Dog": She names her teddy bear Mr. Bear.
- Killer Teddy Bear: The teddy bear she carries will transform into a monstrous guardian protecting her should she be threatened.
- Let's You and Him Fight: With Monster Teddy Bear. This indicates that you are on the route to the bad ending.
- Optional Boss: Choosing to fight Mr.Bear will lead to the Bad Ending Route.
- Third-Person Person: In the Japanese version.
Maki's single mother who works as an engineer at SEBEC. She cares deeply for her daughter and works hard to support her.
- And Then John Was a Zombie: She turns into Hariti during the party's visit to the Haunted Mansion. Whether or not the party decides to fight her, she returns to her true self.
- All There in the Manual: She is only referred to as "Maki's mother" in the Japanese versions of both the original release and the PSP port. She was first named in the Persona World guide, which is used in the American PSP port.
- I Wished You Were Dead: The reason there is no Setsuko in the dream world is likely because of Maki's hatred for her mother.
- Mama Bear: Her love for her daughter somehow transports her into the dream world but also turns her into Hariti.
- Optional Boss: The boss fight against Hariti is optional. Choosing not to fight her will grant the player a Totem later in the game.
- Parental Neglect: Maki hates her mother for not spending enough time with her. In reality, Setsuko deeply loves her daughter and regretted not being with her.
- Screw This, I'm Outta Here!: After learning about Kandori's true intentions, she leaves the company.
- Workaholic: Being a single mother with an ill daughter, she works day and night and rarely visits her daughter in the hospital.
Dr. Nicholai (Nicholas)
A foreign scientist working for SEBEC to create the DEVA System.
- And I Must Scream: When the party returns from the dream world, they encounter Nicholai again, now under Kandori's mind control, spouting about the end of humanity.
- The Atoner: He refuses to help Kandori any further and attempts to sabotage the DEVA System.
- Heroic Sacrifice: He attempts to foil Kandori's plan by locking them both inside the DEVA system and overloading it.
- Mad Scientist: Despite looking like one, he is actually not a bad person.
- No Historical Figures Were Harmed: Likely based on Nikola Tesla.
- Senseless Sacrifice: Whether or not the player chooses to save him, Nicholai's plan fails and Kandori survive.
- Taking You with Me: He tries to take down Kandori by locking them both of them inside the DEVA System.
- What Happened to the Mouse?: His fate following Kandori's demise is unknown.
