A middle-aged, overweight Private Detective who runs the Kuzunoha Detective Agency in Hirasaka (relocated to Kounan in Eternal Punishment). According to rumors, he used to be an incompetent, third-rate detective, but his intelligence spiked due to a mysterious circumstance. As a result, Todoroki is a frequent font of wisdom as well as a reliable authority on the occult. He plays a vital role in Persona 2, uncovering the nature of Sumaru City's curse before even the authorities manage to. Todoroki offers to spread helpful rumors for a fee, thus allowing them to become reality.
- Cool Old Guy: A skilled detective and a devil summoner with a number of connections, including Baofu. Subverted in that the guy using this body is actually pretty young.
- Distinguished Gentleman's Pipe: He carries this with him at all times.
- Grand Theft Me: Although he looks kind of dull and mild-mannered, he works as a Devil Summoner. The explanation for this goes back to Devil Summoner and Soul Hackers. In those games, there is a Devil Summoner and detective named Kyouji Kuzunoha (hence the agency moniker) who loses his body and becomes a body-snatcher. So, when Todoroki suddenly becomes very smart and takes over the Kuzunoha Detective Agency, it's assumed that Kyouji snatched his body. And this is all but outright stated in a piece of dialogue that you can get out of him when you can access Kashihara's case notes, where he mentions something like "The previous owner of this body has left a few notes behind." To cap it off, his bolo tie has as its clasp the Devil Summoner emblem Kyouji used.
- Kavorka Man: Ulala seems to think so, at least.
- Porn Stache
- Private Detective: His occupation. Some of his cases are mentioned through the games, such as the ongoing investigation on each game's Joker, and Junko's - false - suspicions of her husband cheating on her.
- Reasonable Authority Figure: He is the one who cones up with the idea to spread rumours in order to take advantage of them. To the Innocent Sin gang, he is a bit of a mentor to them.
Maki works part-time at Hiiragi Pyschotherapy in Sumaru City in hopes of becoming a therapist like her employer, Reiko. She feels that helping troubled people is the best way for her to cope with the fact that she almost destroyed her hometown because of her fantasy world coming to life and almost completely superimposing the normal one.
She will later receive a flower from the Time Count, and give it to Jun as his ultimate weapon. Maki mentions what she was told by the count about the flower, that it was "the representation of a destiny that must be passed on". Maki will eventually fight alongside her former classmates from St. Hermelin once more to repel the invasion of Sumaru City by Hitler's Last Battalion if certain conditions are met earlier in the game.
In Persona 2: Eternal Punishment, Maki's role as a supporting character is somewhat more significant. She feels the resonance of a Persona from Maya Amano, and is able to tell from this that the latter is acquainted with Yukino Mayuzumi, a former classmate of hers. She later appears at the Science Lab scenario in Kei Nanjo's route. Along with Reiji Kido, she will help Maya's party through the sewer entrance, coordinating their movements with the floodgate controls. Maki will rejoin the rest of her former classmates later in the game, fighting off the New World Order soldiers that are trying to take over the city.
- The Atoner: She feels bad for causing the events of the first game and tries to make amends for it by helping others.
- Beauty Mark: Has one underneath her lips.
- Important Haircut: Maki cut her hair short since we last saw her.
- It May Help You on Your Quest: Have a flower for Jun. Though she only gives it to him if you spread a rumor that the Time Count gave it to her.
- Love Triangle: Both she and Eriko have feelings for the protagonist of the first game, which they both seem aware of. This can especially be seen when they are both waiting for his return at the end of EP.
- Shipper on Deck: She tried to help Eriko to confess her feelings for the protagonist of the first game despite Maki's own feelings for him.
- Strong Family Resemblance: With her hair cut short, she looks like a younger version of her mother from the first game.
- Toy Time: Maki's psychiatry center, Hiiragi Therapy, is painted in this decor. Creepy, yes, but also a Call-Back to Maki's dream world in the previous Persona game.
- Western Zodiac: Gemini.
Brown is a returning character from the first Persona, now a supporting character. Now a popular variety-talk show host, his ego has swelled to the point of no return, especially getting nationwide attention for the rumor that he is the boy toy of actress Junko Kurosu (which turns out to be false, since he actually despises the actress for having as big an ego as he does. Even so, he still addresses the latter as "Junko-chan"). If certain conditions are met, he will fight alongside his former classmates from St. Hermelin once more to repel the invasion of Sumaru City by Hitler's Last Battalion, assisting Tatsuya Suou's party so they can go to Xibalba.
In Eternal Punishment, Brown is still a supporting character. He will assist Maya Amano's party through the Tv studio, scouting out the correct order of Chiruzu's medallions to help them escape the "Kimon Tonkou" spell that has imprisoned them. Hidehiko will rejoin the rest of his former classmates later in the game, fighting off the New World Order soldiers that are trying to take over the city.
- Crouching Moron, Hidden Badass: Yukino remarks he's effective when it counts, and this comes true when he joins his former alumni of St. Hermelin in battle against The Last Battalion/New World Order, depending on the game.
- The Fool
- Mission Control: In Elly's route in Eternal Punishment, he gives hints to Maya and her squad on the locations of the talismans.
- Nice Hat
- Pun: This seems to be his Verbal Tic.
- Small Name, Big Ego: Subverted. While he now gains some popularity, he still brags a lot.
- Western Zodiac: Capricorn.
Like Maki and Brown, Reiji is a returning alumni from the first Persona. He makes an appearance in both Persona 2 games as an NPC. He has long since shed his badass image — even going as far as changing his hairstyle to conceal the scar on his forehead — and is working a door-to-door knife salesman to support his live-in girlfriend (referred to as his wife, whom he married directly out of high school, in the remake of the first Persona) who is carrying his baby. Unfortunately, his Persona still exudes the same kind of intimidating aura, scaring away potential customers. He reluctantly asks for advice from of fellow St. Hermelin alumnus Kenta "Toro" Yokouchi, whose own Persona has made him very successful.
His new hairstyle, however, made him look strikingly similar to his hated stepbrother, so rumors started circulating about Kandori being sighted in Sumaru City, which piques the interest of Kei Nanjo. Reiji can later be found in the Abandoned Factory, where he beats up on demons to blow some steam. Lisa Silverman will 'persuade' him into giving up his Legendary American Gloves.
Later in the game, he will join his former St. Hermelin classmates in the fight against Hitler's Last Battalion unless certain conditions are met earlier in the game. In Eternal Punishment, he will appear in Kei Nanjo's route to the Science Lab. With Maki Sonomura in tow, Reiji will assist in the party's covert infiltration of the lab through the sewers by operating the floodgate controls. He will once again team up with the St. Hermelin alumni later in the game, this time to fend off the New World Order soldiers trying to take over the city.
- Absurdly Youthful Mother: He reveals at the end of Eternal Punishment that his girlfriend is pregnant. He and the rest of the St. Hermelin alumni are 20 in this game, squarely qualifying him for this trope.
- Berserk Button: Never compare him with his half-brother. By the end of Eternal Punishment, however, he seems to have completely let go of his grudge that he named his son partly after him.
- Butt-Monkey: Not only he has a hard time finding a customer, he is forced to give his Legendary American Gloves to Lisa after the girl couldn't stop bothering him with her intense stare. Furthermore, his old classmate mistaken him for his hated half-brother.
- Face of a Thug: Because of his appearance (and his Persona's intimidating aura), he has a hard time looking for customers.
- He Cleans Up Nicely: He drops the bad boy looks after high school and now wears a business suit. Unfortunately, this doesn't help him in finding any customers.
- Happily Married: With an unnamed woman.
- It May Help You on Your Quest: In Innocent Sin, he agrees to fork over his prized gloves in order to be rid of Lisa.
- Meaningful Name: The potential name he picks for his unborn child is built from a kanji from his name and a kanji from Kandori's first name (Takahisa), thus giving us "Takashi.")
- Older and Wiser
- Retired Outlaw: He no longer has the thuggish looks he had in high school.
- Strong Family Resemblance: With his half-brother, Kandori. So much so that rumours began to spread that Kandori, who was dead at the time, was thought to be alive.
- Western Zodiac: Leo
A photographer for Kismet Publishing, and Yukino's boss/mentor. His petnames for Maya and Yukino are "Mackey" and "Yuki".
- Blood from the Mouth: His death. Fortunately, this only happens in Innocent Sin.
- Camera Fiend
- Distressed Dude: He becomes trapped on Mount Katatsumuri while photographing the Nazi invasion. The party arrives too late to save him.
- Going for the Big Scoop: Nazis invading Japan! It's the story of a lifetime! Literally.
- It May Help You on Your Quest: With his last breath, Fujii bequeaths his camera to Yukino.
- Oblivious to Love: Subverted. He seems at the very least aware of Yukino's advances toward him, but considers her more a protégé.
- Red Shirt Reporter
In Innocent Sin, he was a Masked Circle minion under Queen Aquarius who performed the Joker Charm, wishing to become the sexiest man alive. He was interrupted from fighting Tatsuya's group at the fitness club GOLD when an angry Ulala Serizawa chased him out, threatening to kick his ass for stealing her money and suddenly disappearing. In Eternal Punishment, Makimura is pulled out of another scam attempt and taken along while Maya's party searches for Ulala at GOLD, believing that he was the one targeted by the Joker Curse she performed.
- The Casanova: He names a very long list of women he was tricked in the short time he's around the group.
- Con Man: He actually brags about it. Baofu thinks that he's watched too many movies.
- Psycho Ex-Girlfriend: That would be Ulala. Poor bastard.
- Red Herring: Turns out he's not the one Ulala dialed the Joker on, after all. It's Maya.
- The Unfought: In Innocent Sin, he shows up to fight the gang as the boss of GOLD, but then Ulala shows up to kick the crap out of him.
- Western Zodiac: Aquarius.
