Yagami Detective Agency
Voiced by: Shinshu Fuji (Japanese), Crispin Freeman (English)A long-time friend of Yagami, he joined Yagami to work as a PI following his excommunication from the Matsugane family a year before the events of the game.
- Achievements in Ignorance: While the team is going over when the first Mole murders were occurring after finding out the ADDC is involved, he and Hoshino get in an argument and he screams, "Might as well say they killed Waku-san too!" This leads Yagami to realize that Waku was definitely the first victim.
- Badass Beard: He rocks a pretty nice chinstrap.
- The Big Guy: Fights using Kiryu's Brawler style and out of Yagami, Fumiya, Higashi and himself, he does the least thinking.
- Chekhov's Gunman: The incident that got him kicked out of the Matsugane isn't seemingly important at first, at least until Chapter 3 where it's revealed that the robbery was orchestrated by Hamura to get Kaito kicked out of the clan, all so he could assume total control of the Matsugane family.
- Chivalrous Pervert: The guy has a very keen interest in women. That being said, he never does anything unseemly towards them. Regardless, Yagami doesn't consider him timid enough to be a customer with Madoka, if suggested as one to Yosuke.
- Dumb Is Good: He has a good heart but is pretty dim at times.
- Experienced Protagonist: He's been a detective for some time alongside Yagami and an ex-yakuza wakashu.
- Good Old Fisticuffs: As opposed to Yagami being a Bare-Fisted Monk, he's an Unskilled, but Strong street brawler in the vein of Kiryu.
- Heterosexual Life-Partners: With Yagami. The two of them have been best friends for a long time and now work together as PI partners.
- Hot-Blooded: He's loud, brash, and more than willing to throw himself into a fight. His choice of bright clothing seems to reflect this.
- Neighbourhood-Friendly Gangsters: Well, ex-Matsugane yakuza wakashu. He's a nice guy willing to help Yagami out.
- Nice Guy: Kaito's willing to look out for some of the Matsugane wakashus like Toru, who worked with him before he left.
- Noodle Incident: Kaito was kicked out of the Matsugane family by Hamura, though he claims that the incident was his fault. Chapter 3 reveals the incident: a year ago, a thief broke into one of the Matsugane compounds and made off with millions of cash. As the theft occurred under Kaito's watch, he was held accountable for the blunder. And as per the yakuza code, when it was decided that Kaito was to leave the clan, he was to cut off his finger, only for the patriarch to stop Hamura and allow Kaito to leave with his finger intact.
- Red Oni, Blue Oni: Can be considered as the red to Yagami's blue. He's louder and brasher than Yagami, and his fighting style is decidedly less refined.Kaito: (after throwing a sign into a building lobby in broad daylight) HEY! WHERE'S THAT ASSHOLE MURASE?!
- Shipper on Deck: For Yagami and Mafuyu.
- Smarter Than You Look: Kaito isn't completely stupid despite how he acts most of the time. This is best shown in the side case in which he reunites with his old childhood friend Adachi. Yagami ends up finding out that Adachi has grown to become an incredibly vicious real estate agent willing to stoop to lows that give the yakuza pause. Yagami seemingly fails to convince Kaito of his old friend's corruption, but then Kaito reveals that he already suspected it from their first conversation and wanted to confirm it for himself.
- Suspiciously Similar Substitute: Kaito has a number of similarities to former series protagonist Kiryu. He's a heroic bruiser who was excommunicated from the yakuza after taking the blame to ensure the safety of somebody close to him in a crisis situation, and even managed to avoid cutting off his finger due to similar logic to Kiryu in Yakuza 0 (getting officially kicked out of the clan by a high-ranking lieutenant before getting his finger cut off). Of course, their personalities are almost completely different, but Kaito seems to embody the spirit of the franchise's past in his design. He even uses Kiryu's Brawler style when he fights alongside Yagami and in his boss fight.
- Tattooed Crook: Subverted, despite his friendly nature as a Yakuza. He doesn't feel like he has to get a tattoo.
- Unskilled, but Strong: He fights using the Brawler style that Kiryu previously used; the style is based around slow, yet strong swings that lack finesse.
- Vitriolic Best Buds: He and Yagami insult each other pretty regularly. They're also very clearly best friends.
- Wrestler in All of Us: One of the EX-Action moves consists of him grappling with an opponent before doing a Power Bomb. This follows with Yagami kicking the bad guy's face.
- Worf Effect: The Mole kicks his ass even with Higashi helping Kaito.
Voiced by: Junta Terashima (Japanese), Mark Whitten (English)
- Beneath the Mask: Usually comes off as cool and collected, but holds a burning rage against injustice to the point where his former teammate Crow is concerned about him. He noticeably gets accusatory and angry whenever Shinpei Okubo and Emi Terasawa come up. This is because he is Emi's younger brother who really just wants to find the truth behind her murder.
- Big Damn Heroes: Shows up to bail Yagami out of being shot not just once, but four times. The first was from Hamura when the latter tried to have him killed for poking his nose into the Kyorei murders. The second was from Shioya when the Kyorei Clan cornered both him and Kaito as they investigated KJ Art. The third was from the Matsugane family when Yagami's disguise was busted in the infiltration of their building. And the last was from Hamura again when the plan to lure the captain out ended up going badly.
- Bishōnen: Oh yeah. He may just be the prettiest person across the entire franchise.
- Cool Mask: Conceals his identity using a Guy Fawkes mask. After he joins with Yagami, he pretty much ditches it, only putting it back on in certain sequences.
- Connected All Along: As revealed in Chapter 12, Sugiura isn't his true surname; it's Terasawa. He's not actually ex-Kajihira, he's Emi's formerly shut-in younger brother.
- Expy: Not him or most of his major backstory, but his side profession as a thief, being in a group comprised of them, and his alias of "Jester" make him a close ringer for the protagonist of Persona 5, whose Phantom Thief codename is the very similar "Joker".
- Famed In-Story: He and his merry band of thieves are big news in Kamurocho, second only to the yakuza murder cases. The police are unable to catch them on account of his group being ridiculously good at parkour and light on their feet.
- Foolish Sibling, Responsible Sibling: Was the Foolish Sibling to Emi's Responsible Sibling. During Yagami's I See Dead People moment, Emi's spirit tells Yagami to take care of her brother, because she knows how hot-headed and impulsive he can be.
- In the Hood: Wears a gray hoodie aside from his Guy Fawkes mask.
- Irony: His original motivation to help Yagami and Kaito was to betray them at a critical moment as vengeance for acquitting Okubo, who supposedly went on to kill his sister. That quest for revenge ended up revealing that Okubo and by extension Yagami were innocent and helped uncover the actual culprit behind his sister's murder, Shono.
- It's Personal: What drives him throughout the whole story. As more truths come to light, his motivation changes from being ready to retaliate against Yagami to taking down the real culprit. When he and Yagami find Shono in the secret lab, he reveals his true identity as Fumiya Terasawa and immediately tries to stab Shono for the murder of his sister.Fumiya: Three years later, the real killer's finally clear. And now it turns out... Shono... He's the one leading the charge to cure Alzheimer's! He gets to go down in history as a hero!? For what, stabbing my sister to death!? Burning her body!?
- Karmic Thief: Starts the burglary ring to steal from the corrupt and ditches the group after he discovers they were starting to steal for their own benefit instead.
- Le Parkour: It's why Sugiura is so difficult to catch. The only one who can keep up with him is Yagami.
- Lovable Rogue: A snarky Bishōnen righteous thief with a sympathetic backstory who ends up being a major supporting character? Of course he would be popular.
- Spotting the Thread: He's the one who first noticed that it was way too much of a coincidence that Okubo, the man who was accused of killing Waku (Something the others agreed was done by the AD-9 test), killed the girl who got him his innocent plea. It didn't take long for him and Yagami to figure out Shono is behind Emi's murder.
Voiced by: River Kanoff (English), Jun Miyamoto (Japanese)
- Hikkikomori: He used to be one in his own home, but now he's just traded up his home for the internet cafe.
- Playful Hacker: He's usually the one Yagami goes to when he needs to find someone, usually by finding them on Chatter since he hacked himself to have admin privileges.
- Small Role, Big Impact: He's the one that starts up the whole Friend system in the game and is the first one you recruit.
Genda Law Office
Voiced by: Akira Nakao (Japanese), Brian McNamara (English)
- Heroic BSoD: After Shintani's death, he... switches off. He admits that he's just forcing food down and can barely find a reason to get out of bed. Luckily, seeing Yagami be a Determinator inspires him to stop moping and avenge someone he considered a son.
- Ink-Suit Actor: His appearance is based off his Japanese voice actor.
- Nice Guy: While he can have some rough edges, he is ultimately a nice guy who cares for his employees and former employees. He does his best to assure Yagami that he isn't responsible for Emi's death, and he was just doing his job.
- Parental Substitute: Alongside Mitsugi Matsugane, Genda is one of the two people Yagami considers to be like a father figure to him.
- Shipper on Deck: Zig-zagged. At first he sounds like he is upset with Sasori and Hoshino getting together, he is ulimately shown to be supportive.
- What the Hell, Hero?: Ryuzo doesn't like how Yagami has to sink himself by being a hired detective instead of being an attorney despite what happened to Okubo.
Voiced by: Takuya Kirimoto (Japanese), Keythe Farley (English)
- Dirty Old Man: In a flashback he's shown hitting on Terasawa, despite him not being much older.
- He Knows Too Much: Shintani was killed in order to prevent from snooping further to confirm the ADDC's ties with the death of an official who's being investigated by Yagami and the team.
- Small Role, Big Impact: His assassination by the Mole gave Yagami and his allies the idea to investigate the ADDC and their ties to Okubo's case.
- "The Reason You Suck" Speech: During Hamura's trial, the key witness that could lead to him being freed is put into question by Izumida, as the witness was previously threatened by Murase to keep quiet unless he wanted something happened to his sister. Izumida questions if the court can trust his word when Shintani throws that same question right back at him when he reveals Izumida, who previously claimed he hadn't seen the video showing the witness being physically struck by Murase, is also shown in that same footage to be re-enacting the scene on camera. Needless to say, this is what arguably wins Hamura's freedom.
- The Resenter: Greatly envies Yagami because of how Yagami managed to overshadow him despite Shintani being the one who showed him the ropes. Even after Yagami became a Hero with Bad Publicity, people still paid more attention to Yagami's abilities. This envy leads to his death as he attempts to look into the ADDC himself.
- Vitriolic Best Buds: Shintani doesn't really get along with Yagami much. In the prologue scene from before Yagami quit his job as a lawyer, he even butts heads with him. However, the first person Shintani asks for help when he's assigned to defend Hamura in court is Yagami, showing that he still respects his former colleague's skills.
- Wham Line: In Chapter 4.Shintani: Think this is some kind of Yakuza pissing contest, do you? Come on! The Mole is way bigger than you know!Yagami: What do you mean?
Voiced by: Yuko Kaida (Japanese), Aimée Castle (English)
- Amateur Sleuth: Saori helps Yagami and Kaito track down clues regarding The Mole/The ADDC later in the game when you play from her perspective.
- And Now for Someone Completely Different: Certain sections in the game focusing solely on conversation and investigation will have you play as Saori.
- Beautiful All Along: Gets a makeover on two occasions in the story to go undercover and get information using her feminine wiles. A bit of a subversion as even before the makeover Hoshino and a host club employee consider her very attractive.
- Berserk Button: Stealing food from her is a big one. At the start of Chapter 4, when Yagami visits the Genda office because he thinks something major happened, he finds a ragingly pissed Saori accusing Hoshino of stealing a cake that she stuffed in a fridge.note
- Big Eater: Saori enjoys eating a lot, especially if Yagami brings food to the firm. Being accused of eating her cakes is Serious Business!
- Blinding Bangs: Unusual for a series known for fairly realistic characters, but her bangs cover a lot of her eyes. It's a wonder she can see through them.
- Brutal Honesty: Normally, Saori is a very terse person, using as little words as possible that are straight to the point.
- Death Glare: The closest Saori can intimidate people is by giving these to someone, no matter the distance. One example is when Genza unwittingly insults her looks, thus this in retaliation.
- Honey Trap: Saori helps Yagami and the team by posing as a reporter to lure Kido out of the ADDC. They're freaked out that she was able to do it without any prep work needed.
- Meganekko: A rather cute if standoffish young woman who wears glasses.
- Official Couple: With Hoshino in the end.
- She Cleans Up Nicely: Both Hoshino and the club manager can tell right away that with the right clothes and haircut she can be a number one hostess. Yagami has to concede when she sees her all set.
- Shipper on Deck: Is very invested in seeing Yagami return Mafuyu's affections.
- Sweet Tooth: Loves pastries and sweets.
- Unkempt Beauty: She wears rather modest clothing and clearly doesn't take care of her hair. Regardless, several characters, including Hoshino, consider her pretty.
Voiced by: Yuu Hayashi (Japanese), Joe Zieja (English)
- All Love Is Unrequited: Towards Saori. Though at the end of the game, she seems to reciprocate his feelings, as she grabs his hand when Genda accuses him of "a little fling".
- Bunny-Ears Lawyer: The backpack is just because it's more practical than a suitcase. Regardless, Hoshino is still a full-fledged lawyer and good at his job.
- Character Development: Hoshino goes through quite a bit throughout the entire game.
- He starts off as a fresh hire by Genda just learning the ropes under Shintani. Then after Shintani's death, he works alongside Yagami as a sidekick, fully content on embracing the role. Then, midway through Ayabe's trial, Yagami is forced to handle a major problem, leaving the rest in an unprepared Hoshino's hands, making the transition from the sidekick role to full-fledged defense attorney.
- He expresses his own doubts throughout as well, at one point going so far as to blackmail Kido into taking the witness stand during a trial, knowing full well it was the wrong thing to do. All he wanted was to ensure that the bad guys got their comeuppance.
- Hidden Depths: He's apparently really good with ideas on what females should ideally wear or where the nearest hair salon is. He's also a third degree black belt, it's just that fighting is not his thing.
- It's Personal: Hoshino is so angry at Shintani's death that he wanted to help Yagami find the culprit.
- Moment of Weakness: As things get more bleak in beating The Conspiracy, he got desperate enough to try and blackmail Kido into helping them. Afterwards, he realizes the mistake he made and apologized to Yagami for almost crossing the line.
- New Meat: Issei just passed the bar exams and was already starting to work for the office.
Voiced by: Junpei Morita (Japanese), Jamieson Price (English)
- Amoral Attorney: Albeit a sympathetic one. He's in on the AD-9 conspiracy and has been covering for the Mole, but only because he believes AD-9 could prevent tragedies similar to what befell his own family.
- Anti-Villain: He couldn't resist the offer made by Ichinose due to his family being ruined by Alzheimer but he is not proud of it and even stops the Mole from killing Yagami saying he won't cover for it.
- Broken Pedestal: Both Izumida and Mafuyu looks up to him, the latter even having a crush on him when she was young as he made sure her mother's murderer get arrested. They are disheartened to find out he is corrupt.
- Freudian Excuse: He supported AD-9's development because Alzheimer's tore his family apart, with his brother killing their ailing mother and then committing suicide after enduring years of her dementia-induced abuse while being her caretaker.
- Freudian Excuse Is No Excuse: Yagami calls him out on his reasoning, pointing out that he still let an innocent woman die and allowed her boyfriend to be framed.
- Four Eyes, Zero Soul: How he's physically depicted in the game as part of being The Stoic. Subverted as while on the villain side he is compassionate and filled with guilt.
- Laser-Guided Karma: He looked the other way in regards to the AD-9 experiments, and he betrayed the trust of his subordinates in doing so. Those said subordinates end up turning against him and get him charged with abuse of power which ends up ruining his career and putting him in prison.
- Never My Fault: Zig-zagged. When Yagami confronts him over his past, Morita's first reaction is to believe someone betrayed him. Yagami makes it clear that he betrayed his subordinates first with his corruption. Due to Morita's lack of attempts to deny that, he seems to realize that is the truth.
- Not So Stoic: As seen in Villainous Breakdown below.
- The Unfought: Yagami doesn't fight him directly, but with the help of other prosecutors, he ends up being charged with abuse of power charges off-screen and put in prison.
- Silver Fox: Called one by Kaito and was Mafuyu's first crush.
- The Stoic: Doesn't show any emotion that his subordinates/other people in the office are scared to approach him unless it's related to work.
- Villainous Breakdown: It doesn't take long for him to start going through this after Yagami begins questioning his morality in letting the AD-9 conspiracy do what it wants regardless of his excuses.
- Walking Spoiler: In case you can't tell from all the tags, he's a lot more involved with the central plot than it first seems.
Voiced by: Risa Shimizu (Japanese), Cherami Leigh (English)
She's friends with Saori, going back to university when the two of them were studying Law.
- Childhood Friends: With Saori.
- Damsel in Distress: She almost gets kidnapped by Kyorei grunts who intend to take her to a cabaret to lure out Yagami. Yagami saves her just in time.
- Hello, Attorney!: Mafuyu is an attorney, and, as you can see, fairly attractive.
- Likes Older Men: Morita was her First Love, who inspired her to be a prosecutor. It's also implied she really likes Yagami and expresses concern for his well-being, much to the delight of a lot of her friends.
- Nice Girl: Even after the crap Yagami went through, Mafuyu is willing to talk to him, even if it's to just lift his spirits up.
- Ship Tease: Lots with Yagami. She even calls him her boyfriend in one scene.
- Sympathy for the Devil: Expresses some sympathy towards Morita after finding out about his tragic family situation. Yagami, however, points out that Morita still let Emi die and allowed Okubo to be framed.
- Will They or Won't They?: It's never made especially clear what her relationship with Yagami actually is. Yagami's case file states they dated back when he was a lawyer, a claim that Mafuyu denies. But she is clearly carrying a torch for him, and ever refers to Yagami as her boyfriend at one point, and while it's clear Yagami cares for her, it's not made clear if he's romantically interested in her or he see's her just as a friend. The game ends without a solid conclusion in the matter.
- You Have GOT To Be Kidding Me: She has this reactions when she listens to Yagami's excuses for not becoming a lawyer again at the end of the game.
Voiced by: Tsuguo Mogami (Japanese), Ray Chase (English)
- 11th-Hour Ranger: Joins Yagami and his team in taking down The Conspiracy after Morita's betrayal.
- Amoral Attorney: During Hamura's trial, he attempts to cast doubt on a witness's testimony, showing discrimination towards his profession as a host, claiming it makes him inherently untrustworthy. He's also guilty of withholding evidence, claiming not to have known about Hamura's altercation with the host when he, in reality, was involved in a re-enactment.
- Bald of Evil: Well, it's more like a shave, and he isn't evil necessarily. He is a pretty unpleasant man however.
- Butt-Monkey: From other prosecutors after the Okubo case. To get a non-guilty verdict in Japan is already bad, let alone two, but Okubo being charged for murder again a few days after look just as bad on him than it does to Yagami, who at least did his job.
- Epic Fail: He is really bad at his job, his lie about having seen the camera footage is the only reason Hamura walks free and it only takes Emi yelling at him to sway the verdict in the Shinpei Okubo case as he flusters. Yagami even lampshades he only got Shinpei acquitted because he had Izumida as an opponent.
- Everyone Has Standards: He is disturbed by Morita's actions in disregarding what is clearly a crime scene. When Yagami confronts him over him possibly pressuring Mayufu to comply with Morita, it quickly becomes apparent that he is not on Morita's side.
- Framing the Guilty Party: Hamura is a direct accomplice of all the Kyorei's murders, but since Izumida and the police just wants to save face in front of the press and don't have time with piercing a conspiracy they decide to pin him for one murder and make him the sole responsible.
- Good All Along: Turns out that he is one of the prosecutors in the office who isn't in on the AD-9 conspiracy, and after hearing about Morita's involvement in said conspiracy turns around and offers Yagami his unconditional support. Not only that but after joining forces with Yagami he's one of the few people in authority able to help Yagami take down Ichinose, and in doing so was risking both his career and potentially his life if Yagami failed. He was also the one to help authorize the testimonies of both Hamura and Kido during the final trial, and even managed to convince Ichinose to testify as well.
- HeelFace Turn: Zig-zagged. He was never evil, but he was blatantly antagonistic toward Yagami. However, during the final chapter, he joins forces with Yagami to put an end to the AD-9 conspiracy.
- Jerkass Has a Point:
- Though he's not exactly the most pleasant of people to work with, he does point out to Yagami that he still allowed an innocent woman to die by defending Okubo in court, in spite of Yagami stating that all the evidence in Okubo's first trial proving his innocence. Which was reasonable considering the evidence at the time, and it takes the confession of the real killer to reveal the truth.
- He is not exactly wrong to call out the credibility of the witness Seiya, a Host. While he does sort of make it about his occupation, said host also has a history of lying to his customers as long as they keep throwing money at him, receiving around five complaints as a result. You even find the host after he stood up three clients.
- Kick the Son of a Bitch: Considering how much of a bastard Ichinose is, it's really gratifying watching the otherwise unpleasant Izumida constantly dismiss his complaints.
- The Rival: Has major beef with Yagami back in the Okubo case. Even when Yagami leaves the attorney life, Izumida still hates him for humiliating him when Izumida lost the case.
- Rivals Team Up: Joins forces with Yagami to expose Ichinose and everyone involved in AD-9's crimes at the end of the story. Aside from Mafuyu, he turns out to be the only character associated with the police that's not in on the conspiracy.
Voiced by: Tomomichi Nishimura (Japanese), JB Blanc (English)
- A Father to His Men: He considers the rest of the Matsugane Family to be his children, and his subordinates still treat him respectfully despite his decreasing relevance in the clan's actual decision-making process.
- Authority in Name Only: Although he's the patriarch of the family, Hamura's control of the clan's finances has totally displaced Matsugane' influence within the family, leaving him a powerless figurehead.
- Beware the Nice Ones: There is a few moment where he reminds the audience he is still a yakuza patriarch and can shut Yagami up with a few words when they first met.
- Deconstructed Character Archetype: He's basically Kazuma Kiryu if he became a family leader or stayed as leader of the Tojo Clan longer than he ever did. His men think he's soft for being honorable and noble, the family was in financial troubles because said nobility and honor leaves him unwilling to do some of the dark things about Yakuza, and he ends up an Authority in Name Only. He notes that he was in his prime when he wasn't a leader.
- Everyone Has Standards: At first he was okay with Hamura bringing in the money and letting him be a figurehead since he didn't have it in him to do the dirtier stuff the Yakuza do. But after Hamura becomes linked to the Mole killings, beats and disrespects his men, nearly kills Yagami and Kaito several times over, and even pointing a gun at his own patriarch, that's when he's reached his breaking point, and joins Yagami for good.
- Last Disrespects: Hamura feels like how his funeral being held at the Tojo Clan Headquarters where only those closest to him attended made it look like nobody really came. He found that disrespectful to a great man.
- My Greatest Failure: Not stepping up to resolve the family's financial struggles, which forced Hamura to get his hands dirty. He knew Hamura probably crossed a line to get the money but looked the other way because the family was in need of it. As he dies, he apologizes to Hamura for enabling his behavior, saying he doesn't blame him for turning out the way that he did.
- Parental Substitute: Downplayed. While Yagami had a good relationship with his father, he considers Matsugane and Genda to be his other father figures.
- Reasonable Authority Figure: He doesn't have a problem talking to Yagami even after he resigned from being a lawyer. He also interfered when Kaito was expelled from the clan by Hamura and prevented Kaito from losing a finger, and potentially his life.
- Taking the Bullet: He shields Hamura when the Mole comes to dispose of him.
Voiced by: Pierre Taki (original, Japanese), Miou Tanaka (revised, Japanese), Fred Tatasciore (English)
- Almighty Janitor: He is a captain of a third branch yakuza family but he brings a huge amount of money and controls the family to the point no other Tojo clan try absorbing them. It's thanks to his connection with the Mole and Ichinose that Hamura has some police and political influence on top of making the big bucks with assassination service.
- Bad Boss: Berates and beats up his men on little incentive and enjoys forcing new blood to commit murder.
- Condescending Compassion: The nature of his motivation for reducing Matsugane to an Authority in Name Only. He does legitimately care about the patriarch. He just doesn't think Matsugane has it in him to harden his men into a group that could survive the yakuza world.
- The Corrupter: Radicalized the Matsugane family after taking over the finances and kicking Kaito out.
- Dirty Coward: When Yagami starts to win his first fight with the Matsugane family, he forces Kengo to pull a gun on him. And while he's held captive, he loosens his lips, the moment Shioya pulls out his "Instruments." Yagami calls him out on this.Yagami: If you're gonna shoot, you should pull the trigger yourself.
- Dragon-in-Chief: Acts as this for the Matsugane family. By controlling the family's purse strings, he's robbed the patriarch of most of his influence, leaving Matsugane unable to fight his decisions. In short, it's he who has control of the clan and not Matsugane.
- Even Evil Has Standards: He believes that his partners treated Matsugane's death disrespectfully, deliberately making him look like a nobody posthumously when Hamura himself actually had a high opinion of him.
- Evil Sounds Deep: Fred Tatasciore gives him a deep, almost demonic growl.
- Hate Sink: The man has little, if any, redeeming qualities. He treats the protagonist with little respect because of his intent on pursuing a career in court, and takes every opportunity to mock him. In Chapter 2, his every appearance has him brutally harm Yagami when he decides to investigate the Kyorei murders. Not to mention the fact that he orchestrated the burglary incident that led to Kaito being kicked out of the family, all so he could have full control of the Matsugane family. He does show some slightly nobler qualities towards the end of the game and provides Yagami with vital evidence out of respect for Matsugane.
- Heel Realization: After Matsugane is killed, he realizes just how important a man like him was and gives Yagami vital evidence to take down his partners.
- Honor Before Reason: Despite the fact that Hamura doesn't have respect for Yagami, he does make it clear that an assault on Yagami is the same as attacking the Matsugane, given how close Yagami is to the patriarch. Around the start of the game, when a bunch of street thugs attack Yagami, Hamura appears and flat out tells them they're screwed. When Yagami insists that Hamura just let it slide, he tells Yagami that it's impossible because the moment they attacked Yagami, it became Matsugane business.
- Ink-Suit Actor: His appearance in the pre-revision versions of the Japanese release is based off of Pierre Taki. Averted for every other version of the game.
- Jerkass: Though Yagami is treated like a son by the Matsugane patriarch, something the clan is also aware of, Hamura doesn't treat him with much respect. Even when he's put on trial by the police, who are desperate to pin the murders on someone, he refuses to cooperate with Yagami and give him crucial information that could save his ass. In Chapter 2, every single appearance he makes always has him brutally beat up Yagami when he learns that he isn't giving up investigating the Kyorei serial murders.
- He turns this around at the conclusion of the game when he hands over vital evidence to Yagami that immediately implicates Ichinose during Ayabe's trial and takes the stand himself to corroborate it. The smug look he gives Ichinose tells the whole story.
- Jerkass Has a Point: When the Matsugane patriarch was asking him to explain what Kaito was doing, Kyorei mentions that he needed to let Kaito cut his pinky off so that he can show the rest of the family what could happen to them.
- Jumping Off the Slippery Slope: He sought a greater financial base for the family at first to help the family rise up the ranks of the Tojo, a dream that was encouraged by Matsugane. He was even uncomfortable with the idea of killing for money, which was something the Mole actually proposed. It's when he agreed to carry out the hit on Hashiki that he started on his path to becoming the bastard that he is now.
- Kick the Dog:
- Like Hattori, he really likes to rub Yagami's greatest failure in his face, even telling it to a newbie Matsugane thug while Yagami is in front of him.
- When he forces Higashi to kill Red Nose he also creeps him out by saying his girly screams turn him on for no real reason.
- Leitmotif: Rake your inside.
- Man in White: Kyohei Hamura, the intimidating captain of the Matsugane Family, dresses in a white suit.
- Mistreatment-Induced Betrayal: After being incredibly resistant to doing so during his interrogation, Hamura finally reveals the Mole's identity after the Mole attempts to kill him, killing several of his men and Matsugane in the process.
- My God, What Have I Done?: He undergoes this after after Matsugane takes a bullet meant for him and apologizes for being a weak patriarch.
- No Good Deed Goes Unpunished: He was intent on having Kaito cut off his pinky finger for allowing a hundred million to be stolen under his watch a year prior to the story, but Yagami and the Matsugane patriarch prevented this. Yagami also offered Kaito his support, which is a big reason why Hamura hates Yagami's guts.
- Oh, Crap!: Drops a short and effective one when the Mole appears after he's kidnapped.Hamura: Oh fuck...
- Smug Snake: For all his swagger Hamura is still a captain from a low branch family and his fortune comes from connections that will gladly throw him to the wolves if the need arises. He also is less of a physical threat than some of his underlings like Kengo and Ozaki and seriously loses his composure when Yagami gets the drop on him without his gang.
- Tattooed Crook: Subverted, albeit indirectly. Due to Japan's stigma on tattoos, had he gotten one, he definitely wouldn't be allowed in any public sauna, thus not giving him an alibi. If anything, it's a major indication that he's definitely not a yakuza driven by ideals.
- Took a Level in Kindness: After Matsugane dies, he becomes Yagami's ally, giving him vital information to take Ichinose down and later appearing in court to testify himself.
- Wham Line: When he reveals The Mole's identity.Hamura: The Mole is Kuroiwa!
Voiced by: Yoshihisa Kawahara (Japanese), Steve Blum (English)
- A Father to His Men: When he discovers one of his guys being accosted, Higashi personally intervenes. Rather than get angry at his subordinate, he instead tells him it wasn't a problem.
- Break the Cutie: is shown to be timid and polite in flashbacks before Hamura forces him to shoot Red Nose.
- Defeat Means Friendship: After Yagami and Kaito take him on, he agrees to help them take on Hamura secretly and use the Charles arcade parlor as a hideout. He also fights alongside the Yagami Detective Agency during some of the game's greatest battles.
- The Dreaded: To some extent. The thugs who were messing with one of his men quickly back off when they see him.
- It's All My Fault: It becomes clear, thanks to Ayabe, that Higashi blames himself for Kaito being expelled from the Matsugane clan. He was there when the robbery took place and was going to take out a weapon to try and kill the burglar, but Kaito willingly went along with the burglar's demands in order to spare him from the trouble. To try and make up for the mistake, Higashi tracked down the burglar and tried to get the money back.
- Pet the Dog: The first sign that he isn't just another yakuza thug is when he saves one of his men from being shaken down and shows genuine concern for his safety. The second is when he gives a kid money to play arcade games.
- The Reveal: Toru tells Yagami that Kaito was going to get expelled from the Matsugane family under Hamura's watch, even if the patriarch did interfere.
- Took a Level in Kindness: Downplayed, as he's more of a Jerk with a Heart of Gold rather than a full-blown Jerkass, but Higashi gradually becomes nicer to Yagami throughout the game, later becoming a key ally in the process.
- Trapped in Villainy: He's actually a decent guy, even by yakuza standards, but he's forced to answer Hamura's orders. He learned that Hamura was the one who orchestrated Kaito's expulsion from the clan when he tracked down the burglar who stole the hundred million from them, and in order to keep his trap shut, Hamura had him prove his "loyalty" to the clan by forcing him to shoot Red Nose.
- Used to Be a Sweet Kid: A year prior to the events of the game, and two years after Yagami quit being a lawyer, he's shown to be rather timid. In the present, he's become a high-ranking member of the Matsugane and is more than willing to kill Kaito, his former friend, to get to Yagami after Hamura gives the order.
- We Used to Be Friends: He still calls Kaito "aniki," though Kaito states he no longer can call him that since he left the clan.
Voiced by: Mitsuaki Kanuka (Japanese), Mark Allan Stewart and JB Blanc (English)The number two man in Hamura's faction.
- The Dragon: Is Hamura's right-hand man. He notably has more health then Hamura when you fight the two of them together.
- Even Evil Has Standards: When Hamura is about to shoot Higashi Kojiro expresses doubts about it and is shocked that the captain would indiscriminately kill a family member.
- Fat Bastard: He's rather large and rotund. During his first boss fight, he even outright tries to crush Yagami with his body weight.
- Gonk: His face is severely pock-marked and seems to be stuck in a permanent grimace.
- Real Men Wear Pink: Never seen without his Pink Jacket, and is Hamura's heavy hitter.

Voiced by: Shohei Kajikawa (Japanese), Robbie Daymond (English)
- Aerosol Flamethrower: Uses one on Kaito when the family comes bailing Hamura the first time.
- Corrupt the Cutie: As the game goes on, he and the rest of the Matsugane start doing worse actions for Hamura. In his first fight with Yagami he was terrified when Hamura forced him to pull a gun. But when Hamura was taken hostage for interrogation by the Kyorei Clan, the family straps a bomb to Murase. This disturbs Matsugane.
- Defeat Means Friendship: Not entirely. In the final chapter, Yagami and Higashi defeat him and his group. Afterwards, Yagami gets him to understand that going after the Mole would be useless due to him being a cop, but he'd make sure the Mole gets his due karma through the courts. Higashi advises him to help Yagami. When Yagami fights the Mole one-on-one, Kengo and the other members of the family show Yagami support.
- HeelFace Turn: See Defeat Means Friendship
- Honor Before Reason: He wants to go after the Mole despite Yagami warning him that his actions can lead to the family being fully wiped out with no chance to be revived in the future.
- Implied Death Threat: When Yagami tries to tell on Hamura to Matsugane, Kengo tells him Hamura wants to speak to him and warns him not to take his time, or he'll lose his eyes.
- Weapon of Choice: Uses a katana when he fights against Yagami and Higashi inside the office.
- Young Gun: Higashi calls him Hamura's golden boy and while he is new to the family he is among the most violent and authoritative.
Voiced by Ikuji Nose (Japanese), Philip Reich (English),A Matsugane assassin working for Hamura. He fights with a variety of weapons disguised as canes, hence the name.
- Always Someone Better: He has an inferiority complex towards his older twin brother Ryo and joined the yakuza to try to prove his superiority.
- Professional Killer: A yakuza hitman by trade, it's not clear if he is part of the Matsugane family or Hamura hired him from another family.
- Only Known by Their Nickname: He's only ever called "Cane Man". Presumably, his family name is Suzaki like his twin brother Ryo, but he is never referred to as such.
- Sword Cane: His preferred weapon. He also has a knife cane, spear cane, shotgun cane, and tonfa cane.
- What Happened to the Mouse?: He's never seen again after the fight in the Soleil building, while Hamura's other minions Kengo and Ozaki show up again during the endgame.
Voiced by: Sungwon Cho (English)
- Butt-Monkey: When Tashiro's encountered in a story plot, it ends with him getting beaten up by Yagami. To make things worse, Yagami and Kaito strip him when he's KO'd and use his clothing as a disguise for an infiltration mission.
- Slut-Shaming: Downplayed but he spends his session with Madoka sermoning her about being a hostess.

- Flunky Boss: He's flanked by his underlings during his boss battles.
- Friendly Enemy: Despite his family and the Matsugane family being at odds, he and the patriarch actually manage to share a casual chat while Yagami is interrogating Hamura. Then again, Hamura was the one who sparked the conflict to begin with.
- It's Personal: He gets utterly pissed when the Matsugane family straps a suicide vest to Murase, killing him and setting his club on fire.
- Killed Offscreen: He's killed by the AD-9 conspiracy, eyes carved out by the Mole.
- Torture Technician: Implied. We never see him doing it, but he is very enthusiastic about the prospect of interrogating Yagami and Kaito when he corners them the first time. He later mentions off-hand that he knows where the "tools" are when Yagami has to interrogate a captive Hamura for information.
Voiced by: Shinya Honda (Japanese), Adam Croasdell (English)
- Cruel and Unusual Death: Dies with a bomb strapped to his back and goes running back to his family begging for his Captain.
- Honor Before Reason: Murase would rather go after Hamura's faction rather than listen that Kume was killed by someone else, and constantly obstructs Yagami's investigation to ensure Hamura is convicted. It takes Yagami explaining that Hamura was working with the real murderer for Murase to finally let Hamura go.
- Katanas Are Just Better: During the second phase of his first boss fight, he picks up a wooden katana and proves to be a lot more dangerous with it. He then pulls out a real one at the very start his second fight.
- Wake-Up Call Boss: The fight with Murase is meant to show players that the game now implements the Mortal Wounds status if they're hit with bladed/blunt weapons, pistols or by very strong attacks.
- Why Am I Ticking?: The Matsugane family force him to wear a suicide bomb vest when they go to rescue Hamura.
- Arms Dealer: What the gang uses to fund itself; it's proven to be so lucrative that even the yakuza are having trouble keeping up.
- Gang of Hats: Each faction can be identified by their physiques as well as their clothes. Kasai's gang are scrawnier and in street clothes. Honda's gang are muscular and in camo and tank tops. Sakakiba's gang are fat and in tracksuits. Koga's gang are all in business suits and the only ones to use guns.
- Not-So-Harmless Villain: At first they look like a Quirky Miniboss Squad more than anything and are only good for scaring citizens but when Koga starts treating Yagami seriously they starts showing much more power and influence than before. The Keihin gang revenge side case is a good exemple of it.
- Offscreen Villain Dark Matter: The arm dealing explains their fund but doesn't explain how they can smuggle so many firearms in Japan of all places at affordable price for civilians.
Voiced by: Arif S Kinchen (English), Ryouhei Iwase (Japanese)
- The Dark Chick: He is the only one bringing the street gang aspect of the Keihin, Kogo takes care of business, Hondo provides muscle but is too laid back to terrorize citizens and Sakakiba is only motivated by the food Kasai or Kogo offer him. Kasai by being loud and obnoxious increase the demand of guns for Kogo.+
- Dumb Muscle: He's not the brightest bulb but he can still give Yagami a hard time.
- Good Old Fisticuffs: His fighting style is primarily dirty boxing, going for jabs and longer combos instead of grappling or using weapons.
Voiced by: Vic Chao (English), Soichi Abe (Japanese)

- The Dragon: Koga uses him as his main enforcer. Mainly because Kasai and Sakakiba are just good for troublemaking.

- Knight of Cerebus: Of the Keihin gang story, introduction is pretty serious and his prank grenade is more worrying than amusing.
- Not So Stoic: The only time he is at a loss of words is when he sees the gang of idiots Yagami brought with him in the sewer.
- Smart People Wear Glasses: He's the the most wise and and composed of the four, and he shows it with his cool glasses.
Tokyo Metropolitan Police Department

An investigator put onto the serial murder case that surrounds the game's plot. He's from the Organized Crime Division.

- By-the-Book Cop: Is one, and is described by his English voice actor as such.
- Famed In-Story: He's considered a rising star in the police department.
- Ink-Suit Actor: Much like Yagami, his appearance is based off his Japanese voice actor.
- Kick the Dog: Two cases:
- When he first meets Yagami and Kaito, and explains how he became a department punchline over them freeing Hamura, he brings up the Okubo case, trying to get under Yagami's skin.
- Later, when Shintani is murdered and Ayabe is arrested, he taunts him over defending the guy who supposedly killed his co-worker.
- The Perfectionist: According to Ayabe, he's this, which makes him really difficult to work with.
- The Rival: Is this to Yagami on the investigation side of things. He was the one who identified Hamura as the murderer in the first chapter, and he's not happy that Yagami managed to get Hamura acquitted.
Voiced by: Kenichi Takito (Japanese), Matthew Yang King (English)
- Beware the Silly Ones: He may look like a bum and is a Dirty Cop, he's still a very capable cop. And he's not afraid to threaten Yagami to not let slip his secrets or he'll kill him.
- Bunny-Ears Lawyer: He looks like a bum and being a Dirty Cop does lead to the assumption that he's lazy to some degree. He's actually really good at his job, best shown when he provides information on the Matsugane break-in. The police never even bothered to open a proper investigation, so he had to gather up all the information himself. It's even remarked that his information looks like actual police files. Incidentally, he owns a secret casino staffed by Playboy Bunny girls.
- Dirty Cop: Openly admits to being one, using the bribes from the various criminal gangs and doing some favors in return.
- Frame-Up: Ayabe's been accused for killing Shintani, thanks to the Mole and Hamura.
- Friend on the Force: For the detective agency in looking for info that the police can't or won't openly reveal.
- Ink-Suit Actor: Modeled after his Japanese voice actor.
- Knowledge Broker: As stated above, he sells info that the police can't or won't disclose.
- Open Secret: It turns out everyone already knew about his Dirty Cop side-job as well as L'amant. The Conspiracy was just waiting to frame him if necessary.

- Lightning Bruiser: He is fast and can do a lot of damaging attacks.
- The Quiet One: Lets Kuroiwa do the talking.
- Vomiting Cop: Downplayed but he has to restrain himself from throwing up when he sees one of the Mole's victim.
- Climax Boss: He's fought in the ADDC Building in the final long fight of the game.
Kamurocho Burglary Ring
- Even Evil Has Loved Ones: He doesn't admit it until after his boss fight, but despite what he thinks about Jester, he does see him as a good friend and asks Yagami to tell him to slow down from his vigilante actions before he burns himself out.
- Expy: Of Goro Akechi from Persona 5.
- Graceful Loser: After Yagami kicks the shit out of him and tells him to disband, he does so without argument, though not before asking Yagami to look for Jester and tell him to slow down out of concern for his former friend.
- Hypocrite: When Yagami first meets Crow, he says that their burglary ring only steals from the corrupt and are a righteous group. He even preaches this to the new members. When Yagami overhears two members talking about Crow, however, the man doesn't actually do what he says and once took a job from a corporate executive to sabotage the competition for big money. As evidence, most of the members of the burglary ring wear some pretty expensive clothes and accessories. This was what ultimately led to Jester cutting ties with the group.
Advanced Drug Development Center
- Asshole Victim: He sabotaged a medical center so his real boss could get the land. His murder still covers a worse conspiracy.
- Make It Look Like an Accident: The police concluded he died a few weeks after being injured in a brawl. The Mole made sure the death was delayed so the police don't look too much into it.
- The Mole: Kajihira hired him to sabotage the center so it was doomed to close, he also tried leaking anything that could make AD-9 look bad.
- Posthumous Character: All of his appearances alive are in flashbacks.
- You Are Already Dead: He survived the beating but the Mole left him in a condition so severe he could only die from his wound later.
Voiced by: Momoko Taneichi (Japanese), Cassandra Lee (English)A female doctor at the ADDC.
Voiced by: Takaya Hashi (Japanese), Kirk Thornton (English)
- Greater-Scope Villain: Shono may be the one responsible for the murders, but it's Ichinose's bankrolling of AD-9 that pushes everyone else in the ADDC to comply with Shono's demands. Shono probably wouldn't have gotten far if it wasn't for his support.
- Hate Sink: He's a smug Sleazy Politician from the get-go whose every word boils the blood. And he gets a lot worse after The Reveal. Unlike the other people involved, who were either pressured into it or had well-intentioned motives, he's only interested in the profit and fame AD-9 can bring.
- Kick the Son of a Bitch: Once Hamura testifies against Ichinose in the court, he attempts to use his connection to kill the Mole so the case goes moot. While this isn't nice by any means, it couldn't have happened to a worse person.
- Manipulative Bastard: Exploits Morita's family tragedy to get him on their side.
- Sleazy Politician: He's more than willing to use his connections to obstruct Yagami and generally is disrespectful to even members of the law. It later turns out he's also a Corrupt Politician.
- Smug Snake: From the moment he appears on screen, his every word just oozes self-importance.
- Unwitting Pawn: Too self absorbed in the promise of power and the like to question if Shono can actually cure Alzheimer disease despite repeated failures and the clearly unsafe and insane methods, he just enables Shono's delusions for nothing.
- Villainous Breakdown: As Ayabe's trial goes on with him on the stand, he starts to lose it.
- You Have Out Lived Your Usefulness: Has his subordinate order the deaths of the Mole and Shono to keep them from being used against him in court.
Voiced by: Mitsuru Ogata (Japanese), Todd Haberkorn (English)Ichinose's subordinate and his middleman.
- Dissonant Serenity: Calmly smiles as he requests kidnappings and assassinations.
- The Dragon: To Ichinose.
- Forehead of Doom: He has a rather tall forehead.
- Gonk: Looks like the love child of Katsuragi and Areshi.
- Mouth of Sauron: He's Ichinose's middleman as well as Shono's. If the Mole has to make a hit, he's the one who gives the order.
- Non-Standard Character Design: His face has unnervingly cartoonish proportions with tiny narrow eyes, wide mouth, and large ears, which makes him stand out in a series full of otherwise realistic characters.
- Properly Paranoid: By far one of the more frustrating suspects to tail, as he takes a pointlessly circuitous route to his destination with random detours that leave little cover to hide behind, while constantly stopping to look over his shoulder and even occasionally doubling back after rounding a corner to make sure he's not being followed (which of course, he is).
- Red Right Hand: His gigantic ears.
- Sharp-Dressed Man: Reported to be seen in a suit and tie with black gloves.
Voiced by: Hiroshi Shirokuma (Japanese), Andrew Morgado (English)
- Boss in Mook's Clothing: The fight against him is important story-wise, but he fights like a generic street thug.
- Butt-Monkey: He goes through a lot of humiliation throughout the game. He first gets pressured into supporting Shono's experiments as revealing AD-9's failure to public would destroy both of their careers, is later kidnapped by Yagami and co. and forced to strip and reveal everything he knows about AD-9, and ultimately ends up admitting his own part in Shono's illegal experiments at the court.
- Dirty Old Man: Yagami and his friends use this to lure him out and blackmail him into revealing the truth behind Shono's experiments by having Saori try to seduce him.
- Even Evil Has Standards: Kido had a few sex scandals under his belt and covered Shono's experiments but he never wanted any of the murder to happen and was blackmailed into obeying Shono.
- Forced into Evil: Shono gets him to cover up his experiments by threatening to ruin both their reputations. In the present, he's clearly angry that he allowed himself to give into Shono's demands.
- Ineffectual Sympathetic Villain: While he is responsible for covering up Shono's illegal experiments, he is pressured into villainy by Shono (his initial reaction upon hearing AD-9's failure from Shono is to say he will resign before Shono threatens him with his career) and is shown to be so pathetic with lots of bad things happening to him throughout the game that he can come across as this.
- Red Herring: He's this for Shono. Until Yagami and Kaito learned the truth they thought he was behind the Mole Murders.
- You're Insane!: Says this when Shono makes it clear he's going to blackmail him to help.Kido: Shono...You're mad.

- Intrepid Reporter: His hounding of Yagami eventually leads him to the mystery murders surrounding Kamurocho. Despite his sleziness, he's actually a damn good journalist. He's the first person to find out just why the Kyorei are in Kamurocho and he's versed enough in medical jargon to help Yagami understand the AD9 studies.
- Jerkass: The guy is sleazy, smug prick. And he never apologizes about it.
- Kick the Dog:
- Like Hamura, he likes to rub salt in Yagami's wound. He was the one who published the story that led to Yagami being ostracized by his fellow lawyers after Okubo killed again not long after his release. When they meet again after Hamura's trial and figures out that he was one of the reasons why Hamura was made a free man, he brings up his past failure and that the parents of Emi, Okubo's deceased girlfriend, are still grieving.
- He sets up Mafuyu to be kidnapped by the Kyorei clan and doesn't even try to apologize about it.
- Punch-Clock Hero: He helps Yagami uncover the truth, but it's mostly because Kajihira is paying him to do so.

Later, he's found to be the detective Mafuyu uses to uncover Morita's background.
Voiced by: Shinji Kawada (Japanese), Yuri Lowenthal (English)The last client of the Genda Law Office when Yagami was a lawyer. After Okubo was acquitted of dumping a dead corpse from a murder while working with the ADDC, he was arrested again for committing arson.
At the start of the game, Okubo is on Death Row awaiting his execution.
- Cassandra Truth: He insists he was completely innocent of the two murders, but no one believes him because of his criminal record.
- Death Row: Was convicted for the supposed murder of his girlfriend. By the time the game's events begin, he only has several days left before he is executed. Yagami eventually manages to prove that Emi's death wasn't his fault, and a trial to formalize his exoneration is set in stone when the main plot ends.
- Digging Yourself Deeper: Fearing no one would believe him because of his criminal record he buried Waku's body in the mountains. That really didn't help his case.
- Informed Flaw: Supposedly, he has quite the violent temper, but we never see it for ourselves. Then again, Izumida was the one characterizing him, and he has demonstrated that he's willing to cast anyone in a negative light to get a guilty verdict. He does have a record for breaking his ex girlfriend's finger while drunk but he deeply regrets it and never touched a drink ever since.
- It's All My Fault: Despite saying he is innocent he still blames himself over what happened to Emi and Yagami. His logic being that his attempt at a disposing of Waku's body despite not having killed him lead to the Disaster Dominoes.
- Off on a Technicality: Yagami got him off his first murder charge thanks to one of those and Emi's outburst at court. By destroying Shono's testimony Yagami could prove the time window for the murder is bigger than the one that makes Okubo the killer without a doubt. However his criminal record, lack of alibi, potential motive and his attempt at disposing of the body made him guilty in the eyes of the public.
- Reformed, but Rejected: He has a criminal record, something that was brought up in both his court cases to point to him as the murderer.
- Small Role, Big Impact: His arrest led Yagami to resign from the law firm and eventually investigate it after a murder case he's working with Kaito has some ties to his arrest.
- Tears of Joy: He breaks down into happy tears when Yagami tells Okubo that he believes Okubo didn't kill Emi.
Voiced by: Eri Goda (Japanese), Amy Walker (English)
- All Girls Want Bad Boys: Subverted. Even though Okubo has a criminal record, Emi firmly believed Okubo was a kind and gentle man at heart.
- Horrible Judge of Character: Was one of the few people to vouch for Okubo's innocence without any hesitation. Okubo then apparently murdered her. Turns out she was correct in believing Okubo's innocence, though she was off-base with her assessment of Shono. Then again, Shono doesn't exactly look like a murderer.
- Posthumous Character: She's been dead for three years, but her importance to the plot cannot be overstated.
- Suspiciously Similar Substitute: To Makoto Makimura, and to some extent, Wen Hai Lee from Yakuza 0. Both have very similar hairstyles and similar attire.

- Affably Evil: He may have the mentality of a Yakuza but he's nothing but proper and polite.
- All for Nothing: Before the story he tried to buy up the land the Medical Institute (And thus the ADDC included) so that he could redevelop the area into a Kamurocho expansion. This all came undone when AD-9 was announced. And given that he is being investigated in the epilogue, it's likely he'll be in jail by the time the land is up for sale again.Kajihira: Now I'm 100 billion yen in the red.Kaito: That's a lot of money!
- Be Careful What You Wish For: He seeks to expose the conspiracy at the ADDC to protect his own shady investments. In the ending, Saori mentions that Yagami exposing the conspiracy has led the government to begin an investigation into Kajihira and Kanzaki's dealings that will likely send both men to jail.
- Corrupt Corporate Executive: He's funding a yakuza clan, after all, though in a odd twist, once he's met, he makes sure that the Kyorei clan assists Yagami and co. in their investigation.
- Evil Cripple: A wheelchair user who sponsors a yakuza clan.
- The Man Behind the Man: The secret master behind the Kyorei clan's activity in Kamurocho.
- Pet the Dog: While greed is his primary motivation he wishes Yagami could uncover the truth if not for his land development scheme to work at least to give Hashiki proper respect.
- Off Screen Villain Dark Matter: His presence subvert thie for the Kyorei clan. The Kyorei are too small to venture that far from Kansai on their own but thanks to Kajihira's financial support they can build themselves in Tojo territory with only the Matsugane family bothering them.

- Butt-Monkey: She manages to wind up the target of nearly every pervert in Kamurocho.
- Half-Identical Twins: Her twin brother Yosuke looks just like her with shorter hair.
Voiced by: Naoto Takeda (Japanese),A foreigner training to be a ninja. If Yagami makes friends with him, he sometimes helps out in fights by using his ninja skills and his ninjato.
- Chaste Hero: Believes so and think of his grandma naked to repel impure thoughts. It makes him a perfect customer for Madoka as he won't make a movde on her and he likes to talk without the person replying.
- Chuunibyou: His "anime bullshit" aggravates Yagami to no end.
- Highly Visible Ninja: He can be seen casually walking around town after recruiting him, especially in broad daylight. It gets subverted during the finale of "The Golden Mouse" when his own outfit blends in quite well to the Kamurocho sewers.
- McNinja: A foreigner who's in Japan to train in the ninja arts.
- Reverse Grip: He holds his ninjato in this manner.
Voiced by: Ikuji Nose (Japanese)A self-titled 'free spirit'; by that, he means he consumes spirits freely. He's also the older twin brother of a mini-boss, the Cane Man, and is available shortly after fighting the latter in the Soleil building. He's usually found in the Earth Angel bar.
- Always Identical Twins: It trips Yagami up at first, as they even dress the same. Ryo doesn't take it too personally.
- The Alcoholic: His primary raison d'être; progressing his friendship requires Yagami to outdrink him, which is done by investing in the Borderline Alcoholic skill.
- Big Brother Worship: His brother looks up to him, and has also been trying to one-up him since they were kids. Ryo notes that his younger brother's choice of clothing is likely another one of his attempts at such.
- Cloud Cuckoo Lander: Granted he is likely drunk off his ass but his prose tends to be strange a bit. He also fondly remembers how he and his brother used to fight for their mother's milk when sent to Madoka.
- Evil Twin: What the Cane Man is to Ryo; while the latter sticks to legal pursuits (such as drinking himself 'til sundown), the Cane Man prefers to operate as an assassin.
- Lazy Bum: He is proud of being an unemployed drunk.
- Chivalrous Pervert: Yosuke cheats on his girlfriend, makes weirdly suggestive comments about his sister and Yagami, and shows occasional sympathy for the Twisted Trio. However, he also asks Yagami to help Madoka, a childhood friend of his, pay off her debts so she can quit a sex work job that she's uncomfortable in. Yosuke also requests that Yagami not let Madoka know that Yosuke is helping her, because he just wants to help his friend and doesn't want a reward for doing so.
- Half-Identical Twins: He looks like his twin sister Tsukino with shorter hair. This bites him in the ass when Ass Catchem gropes him believing him to be Tsukino with a short haircut.
- Shipper on Deck: He's the one who suggests that Yagami date Tsukino.
- Harder Than Hard: After Yagami has cleared all the batting challenges, he gives him two new ones that are meant to be this to the common man.

Voiced by: Shosuke Tanihara (Japanese), Matthew Mercer (English)
As it turns out, The Mole is none other than Mitsuru Kuroiwa, the investigator put onto the serial murder case. A Dirty Cop on a far worse level than Ayabe.
- Animal Motif: Yagami calls him the Mole because he appears at dark times, not unlike an actual mole. The fact he's a Dirty Cop (A police officer's mole) was not found out until later.
- Arrogant Kung-Fu Guy: He's completely assured of his victory both times he fights Yagami, and he really doesn't take it well when Yagami manages to get one over him.
- Assassin Outclassin': He dispatches of Ichinose's hitmen in a second.
- Axe-Crazy: Though the eye-gouging is given an explanation, once he's revealed, it becomes clear that he really isn't stable.
- Battle in the Rain: Sort of. His and Yagami's last fight takes place indoors during a storm, but the surrounding windows are either open or shattered, allowing the rain to pour in.
- Bling Bling BANG: His pistol, while operating as The Mole, is a gold-plated Smith & Wesson 3913.
- Break the Haughty: The final chapter is this for him. He gets a humiliating defeat by Yagami, the bosses he put so much faith in decide to send a hit squad for him so they'd save their own skin. And he goes down fighting at the ADDC where all of his crimes are revealed to the cops, dying in a pool of his own blood.
- Combat Pragmatism: After Yagami gains the upper hand in their first battle he pulls out his gun. If it wasn't from Mori he would have shot Yagami without batting an eye.
- Curb-Stomp Battle: Delivers one to everyone but Yagami, he even destroyed Kaito and Higashi with only a blackjack.
- Determinator: The man will not stop until his objective is complete or he is dead. Even after Yagami delivers brutal beatdown on him, he still has enough energy to try and kill Shono and it takes several cops' pumping him full of lead to finally put him down for good.
- Dirty Cop: Is revealed to be a much worse case of this than Ayabe.
- Disney Death: Averted. Yagami kicks him out of a window but Kuroiwa hangs onto the ledge and climbs back in, and that's when you realize that was only Phase 1 of his boss fight.
- The Dreaded: His actions have scared the crap out of anyone in Kamurucho, even the police and the criminal gangs.
- Establishing Character Moment: Slowly walks in a flaming building to kill his former partner, when this fails he kills everyone coming near him with his gun and fists only to take one as a human shield that he makes sure to kill before escaping. As the Mole Kuroiwa is completely ruthless, unflappable and enjoys murder.
- Even Evil Had Loved Ones: Maybe. Ayabe claims it's a possibility that Kuroiwa murdered the man who snitched on his Dirty Cop boss (Who then committed suicide) for revenge.
- Even Evil Has Standards: Downplayed. When he confronts Yagami in L'Amant, Morita demanded to know why he was there. Kuroiwa immediately insulted him by reminding him how good he is at turning a blind eye, implying even he thought it was a low to betray his own ideals.
- Evil Counterpart: To Yagami. They have similar fighting styles, are both considered attractive by other characters and both work as law enforcement. However, Kuroiwa commits the murders that Yagami investigates.
- Eviler Than Thou: To Hamura. It was Kuroiwa who suggested they take on assassination jobs, which Hamura was actually uncomfortable with at the time. Judging by the look on Hamura's face, Hamura also wasn't expecting Kuroiwa to so readily execute him after he was captured by Yagami.
- Evil Laugh: During his mortal wound charge up he starts laughing.
- Final Boss: A 1-on-1 battle with him in the ADDC is the final battle of the game.
- Final Boss Preview: He's fought earlier in the final chapter. Unlike most examples, you're expected to win, though he doesn't pull out all the moves that he does during his final battle.
- Hate Sink: Kuroiwa's true colors are incredibly unpleasant, being a mix of deluded self-righteousness and sadism.
- The Heavy: He's the biggest physical threat in the game, the enforcer of The Conspiracy's will, and the Final Boss.
- Hypocrite: He looks down on Ayabe for being a Knowledge Broker when he was in the exact same profession prior to doing assassination jobs.
- Implacable Man: It doesn't matter how much punishment he receives. He'll always get back up. He's only done in after getting utterly ventilated with bullets, and even then it still takes some time for him to finally die.
- Institutional Allegiance Concealment: Kuroiwa disguises himself as The Mole by hiding his face with a hoodie/mask.
- In the Hood: Has a hood worn over his head/face.
- Karmic Death: After killing many people using various methods, including with a gun, it befitting he ends up shot numerous times by police officers.
- Killer Cop: Killed the three Kyorei clan members at night. He also kills the other TMPD officers in the ADDC after they go after him.
- Knight Templar: He's willing to kill as many test subjects as it takes to complete AD-9, believing that he and Shono will be hailed as heroes.
- Leitmotif: "Penumbra" for all fights against him. Fitting for a serial killer who destroyed countless lives while appearing as the ace detective in public.
- Lightning Bruiser: He uses the same flashy acrobatics in combat that Yagami does and can take an absurd amount of punishment before going down.
- Marathon Boss: Across two phases, his last boss fight has a total of 10 health bars, the most for any Non Bonus Boss fight across the franchise.
- Mirror Boss: He fights using more vicious variants of Yagami's moves.
- Meaningful Name: The kanji for "Mitsuru" can mean satisfy, symbolizing his perfectionism and the "Kuro" in "Kuroiwa" means black which is associated with sin in Japan.
- No-Nonsense Nemesis: He's ruthlessly efficient when he's given an objective, sparing little talk and just killing everyone in his path.
- The Paragon Always Rebels: Subverted in that he never really was a paragon, being a Bastard Understudy from a crooked cop, but he was seen as The Ace of the precinct by Ayabe and the public.
- Purple Is Powerful: Has a purple Battle Aura and is an absolutely vicious combatant.
- "Reason You Suck" Speech: He gives a short and effective one to Morita. When Kurosawa is about to fight Yagami, he advises Morita to look the other way since he's good at that. It doubles as a Stealth Insult.
- Sadist: He seems to relish causing pain considering the rather broad smile he has while doing so.
- Serial Killer: Double subverted. Yagami initially believes that the Mole is a serial killer whose MO is murdering Yakuza by gouging their eyes out, but it turns out that he's an assassin for hire who is covering up illegal experiments on humans. However, Kuroiwa comes to enjoy murdering people in such a ritualistic manner, and by the end of the game, he's killing for enjoyment rather than profit.
- Shot to the Heart: Injects himself with something during his last fight with Yagami that significantly boosts his strength.
- Smug Snake: While Yagami and his friends are chasing after them, he gives them 'grins' since he believes that his men will be enough to stop them rather than fighting them himself.
- The Sociopath: He's a sadist with a profound Lack of Empathy. Even back when he was just a Knowledge Broker, Hamura could tell he was a man who could kill without feeling a shred of remorse.
- Taking You with Me: Effectively what he tries to do in the game's climax. After Ichinose orders his death, Kuroiwa attempts to hold Shono hostage to force him to complete AD-9 or, in the case that the authorities corner him, kill him before he's gunned down himself.
- This Explains So Much: Despite being the one responsible for enforcing the will of The Conspiracy, he doesn't actually know why the eyes of the victims are cut out before he witnesses Shono's horrifying death when he looks in his blue-dyed eyes, leading to his Famous Last Words.Kuroiwa: So that's why... I finally... Understand...
- Villain with Good Publicity: A known plainclothes officer who does part-time work as the Mole. This collapses after his true identity is revealed.
- Villainous Breakdown: He undergoes it as soon his identity is revealed. When Yagami puts up a good fight against him, even having him on the defensive, he ends up pulling out a gun and nearly shooting Yagami down. The only reason he doesn't is when Morita reminds him that he can't cover his tracks if he kills Yagami now. When Ichinose puts a hit on him as the conspiracy is falling apart, he plans on kidnapping Shono so they can keep working on AD-9, rationalizing that no one will care about his rampage if he ends up curing Alzheimer. He then tries to kill Shono when that's off the table.
Voiced by: Makoto Nagai (Japanese), Michael Gough (English)
- Axe-Crazy: A more subdued example compared to Kuroiwa, but his actions definitely point to him being at least slightly unhinged. Accidentally killing a patient and panicking and hastily attempting to dispose of the body? Understandable. Killing a coworker in cold blood just to frame her boyfriend and having their house set on fire? Definitely not.
- Believing Your Own Lies: He found out the toxins in AD-9 were impossible to remove but ended up convincing himself that he could negate their effects after insisting to others that he just needed to test the drug out more. He ultimately dies as a result of injecting himself with what he believes to be a perfect dose.
- Beneath Suspicion: He looks like an Extreme Doormat and even when Emi points out the hole in his testimony she and everyone thinks he just misremember instead of covering himself.
- Big Bad: It's his willingness to cross every moral line for the sake of AD-9 that drives the conflict. Every other villain involved with the plot exists to ensure his work is completed.
- Bitch in Sheep's Clothing: At first, it seems like he's just a weak-willed man being pushed around by his corrupt superiors. Then it's revealed that he's really the one who started The Conspiracy.
- Body Motifs: Eyes. He gouges out the eyes of his victims to keep the experiments a secret. When he makes eye contact he looks either terrified, guilty, or crazy. He "Keeps his eye on the ball," if you will. And he Dies Wide Open.
- Classic Villain: He embodies pride, as he only performs experiments with AD-9 because he made it, despite knowing that it can't be improved.
- Covert Pervert: The hostess recalls that Shono kept peeking nervously at her cleavage when Hashiki invited him to the club.
- Creepy Blue Eyes: As he dies, it's revealed that this is a side effect of AD-9.
- Determinator: He will do whatever it takes to cure Alzheimer's Disease. Deconstructed thoroughly in that he crosses every moral line he can to do it, doesn't let anyone else work on his drug, and refused to Know When to Fold 'Em when it became apparent that everything he is doing is All for Nothing.
- Diabolus ex Nihilo: Got two big ones that helped him cover Waku's death: first is that Okubo freaked out so bad he tried to hide the body, which made him the prime suspect and even his Off on a Technicality didn't stop the public of thinking he was behind it. The second is that due to that Okubo was using sleeping medicine because of the harassment so it was easy for Shono to kill Emi and frame an unconscious Okubo.
- Dies Wide Open: And how! One of the negative side-effects of AD-9 - aside from it causing excruciating pain and killing whoever takes it, obviously - is that it gives the victim bright blue eyes, something revealed to horrifying effect just after he injects the drug into himself to prove that it's safe. The last we see of him is his dead body, with wide-open bright blue eyes and his face contorted in agony.
- Dirty Coward: Whimpers and runs away from Yagami, calling reinforcements and begging Yagami to stop chasing him during the 2nd fight with Mashiko.
- Engineered Public Confession: Suguira records him on his phone while he admits to murdering Emi. This is the final piece of evidence that allows them to take down Ichinose.
- Even Evil Has Standards: One of the reasons he gave for why the Kyorei were used in the AD-9 experiments besides the fact they were in his way; he would rather use yakuza as test subjects instead of innocent civilians.
- Eye Scream: He was the one removing the eyeballs from his victims. It was so people wouldn't suspect human experimentation as the eyes turns blue. Even Kuroiwa from his reaction wasn't aware of it.
- Freudian Excuse: His mother and grandparents were both taken by Alzheimer's, which pushed him towards finding a cure through any means necessary.
- Freudian Excuse Is No Excuse: Yagami counters all of his "Greater Good" talk by pointing out how many people he killed, including Emi-Chan, who was only killed so he could frame Okubo. Yagami also points out he could have let someone else carry on his research but his pride stopped him.
- I've Come Too Far: His main motivation on continuing the development of AD-9 himself, even with the murder of an innocent woman, patient and several yakuza, and proven failure of AD-9 in humans on the back of his mind.
- Karmic Death: Dies exactly the same way like his first victim by believing he has perfected the drug by injecting it into himself. This time however, there was nothing to keep him from hiding that from the public. Sugira even recorded his confession and death which would proved to the world he was nothing more than a hopeless scientist who used others for his ambitions.
- Mad Scientist: Experimented on countless humans just to perfect his drug even after it became obvious that it would be impossible to remove the drug's toxins.
- Manipulative Bastard: He lets Kido share most of the fame about the drug before telling him the drug doesn't work and he killed someone. He also turns Hashiki's attempt at having him confess about AD-9's foul play in a trap to murder him.
- Motive Rant: Delivers one when he makes a "Perfect" dose of AD-9.Shono: AD-9 is done now. Everything I have has gone into this one syringe. There's no mistaking it this time. Here's the proof. I'm going to show you once and for all. I'll prove that my miracle drug is a reality!Yagami: How many people has your "miracle" killed?Shono: People... People? But it'll save millions! Maybe tens of millions across the world!Yagami: That's why you thought it was okay to murder an innocent woman? Huh? Is that why you stabbed her to death and burned the evidence!? Okubo-kun took the fall for all of it... You sent a good man to die!Shono: I never wanted to kill anyone! But it had to happen for AD-9. It was the only way to save all of them!(...)Shono: But AD-9 is my drug! I'm the only one who could have finished it! And I'll finally prove it! Prove that my research was worth the effort! Prove that I was right to do what I did!
- Narcissist: The reason he refused to pass on his research to someone else is because he created the drug.
- Nervous Wreck: He speaks with a constantly wavering cadence and always looks incredibly uncomfortable in whatever situation he's in. It's possibly a result of his fears of being caught and his need to constantly reaffirm that the sacrifices he's made aren't pointless. Emi mentions he used to be more matter-of-factly and calm when he talks so it is a new development for him.
- Non-Action Big Bad: His physical constitution doesn't lend itself to physical combat, and the only murders he committed were against similarly-defenseless people.
- Not-So-Well-Intentioned Extremist: His argument that his drug will save the lives of countless millions and is thus worth the sacrifices sort of loses weight when it's revealed that he knew the drug's toxins were impossible to remove. Him continuing to experiment on people is just him desperately trying to escape the reality that all those sacrifices were for nothing, which ultimately comes back to give him a rather gruesome demise.
- Playing with Syringes: The entire plot started when he performed an illegal experiment on Waku. He continues to perform deadly AD-9 experiments on kidnapped test subjects.
- Professor Guinea Pig: He decides to test the perfected AD-9 on himself. It kills him in the same horrific manner as his victims.
- Screw the Rules, I'm Doing What's Right!: Everything he does, he does because he thinks it's the right thing to do. Horribly deconstructed given that all his actions do is kill people and ruin innocent lives. And the longer the experiments are drawn out, the more self-righteous he gets with more heinous crimes. By the end, it gets to the point that he's only doing it to show he was right.
- Self-Made Man: He paid his tuition at medical school by himself and became a respected doctor. Then he went crazy with AD-9 working on mice but not humans and ensnared his director and the vice minister of Health into bankrolling him.
- The Dog Was the Mastermind: Absolutely nobody suspected him of even being apart of The Conspiracy until Yagami confronted Hamura.
- They Look Just Like Everyone Else!: He doesn't look like the kind of man who could hurt a fly even if he wanted to. Then you find out that he's done so much worse than that.
