Character sheet for the Armed Detective Agency of Bungo Stray Dogs. Characters on this page all have their names listed in Western order— given names followed by surnames.

The Armed Detective Agency (武装探偵社, Busoutanteisha)'s members have supernatural powers. They primarily take on cases that the police or the government are unable to handle, but they also do regular detective work. Their director is Yukichi Fukuzawa, but most of their day-to-day business is managed by Doppo Kunikida.


Spoilers up to the end of the Cannibalism arc are unmarked.

    In General 
  • Badass Crew: Don't screw with them. They will and can kick your butt into next week, should you anger them and/or target one of them.
  • Five-Man Band: An interesting example, since Atsushi is the main protagonist of the series, yet isn't the leader of the Agency, meaning the roles are:
    • Supporting Leader: Officially Fukuzawa, but Kunikida takes over once Fukuzawa is stashed away in Anne's Room because of a looming virus threat that would affect him and Mori, and even Ranpo fulfills this role at one point. More information about that here. Obvious spoilers.
    • The Lancer/The Heart: Atsushi, who works together with Kunikida and Dazai and seems to hold the team together.
    • The Big Guy: Yosano, Kenji and Ranpo. Yosano doesn't hesitate threatening people who bother her, Kenji often attacks before he thinks, while Ranpo boasts how (supposedly) powerful his Ability is.
    • The Smart Guy: Kunikida and Dazai fulfill both this role. While Kunikida was a former math teacher, Dazai has shown on various moments he is a hidden genius as well.
    • The Chick: Kyouka seems to be the odd one out. Her costume is the most traditional, at any rate. (not counting Fukuzawa) Tanizaki may count as well, since his Ability isn't that good for fighting, but it is good at scouting.
    • Team Pet: Mii-chan, Kirako's cat.
  • Foil: To the Port Mafia. They both tend to recruit young members and both of them work to protect the city. However, the Port Mafia works in darkness and the Agency in light.
  • The Good, the Bad, and the Evil: The good to the Port Mafia's bad and the Guild's (and later, the Rats in the House of the Dead's) evil.
  • Good Thing You Can Heal: Yosano's healing Ability means that the Agency members (minus Dazai, see Logical Weakness under his entry) can take on serious injuries and then be back on their feet within a few chapters. Additionally, regeneration is part of Atsushi's Combo Platter Powers.
  • Putting the Band Back Together: In the plot of the Hunting Dogs arc, Atsushi and Kyouka try to get the other members back.
  • Ragtag Bunch of Misfits: A Classical Anti-Hero orphan who just happens to be a weretiger, a Cloudcuckoolander Sociopathic Hero (who's also an ex-mafioso), a Control Freak Only Sane Man, an Insufferable Genius Manchild who's in denial about his status as the The Team Normal, a Combat Medic with sadistic tendencies regarding patients, an incredibly naive country hick with Super Strength, a Master of Illusion who goes from a Nice Guy to down right terrifying when his sister is threatened, and a Little Miss Badass reformed assassin. All lead by a Perpetual Frowner who remains stoic even when experiencing Cuteness Proximity.
  • Secret Test of Character: Each prospective member is required to pass one in order to join.
  • The Hero: They're generally portrayed as the most noble and most just of all the groups.
  • True Companions: For Atsushi.
  • Two Girls to a Team: Yosano and Kyouka are the only female members of the "main" Agency (meaning not counting the office staff).

Yukichi Fukuzawa

福沢諭吉 - 人上人不造 note 
Literary references: He is named after Japanese author Yukichi Fukuzawa, and his ability is a reference to one of the texts from Fukuzawa's essay collection An Encouragement of Learning.

Age: 45
Height: 186 cm
Blood Type: B
Birthday: January 10
Zodiac Sign: Capricorn
First appearance: Chapter 2/Episode 2

The director of the Armed Detective Agency, his ability, "All Men are Equal," lets him suppress the abilities of his subordinates.

  • Badass in Charge: He's a skilled martial artist and Kunikida's master to boot. Kunikida has never been able to beat Fukuzawa in a fight and Fukuzawa can fight off a group of assassins with ease.
  • Benevolent Boss: Cares for his subordinates and will always put their welfare first.
  • Big Good: Head of the Armed Detective Agency, dedicated to fighting crime and saving innocent lives.
  • Coat Cape: He wears his haori over his shoulders like a cape.
  • The Comically Serious: Serious at all times, even when dealing with his workers' antics and trying to pet a cat.
  • Cuteness Proximity: Hires Kyoka on the spot after she makes a cute face. Fukuzawa is also very fond of cats.
  • Da Chief: A traditional Japanese equivalent (right down to the katana!) to the Agency, especially to Ranpo.
  • A Father to His Men: Orders Kunikida to find Atsushi's whereabouts and rescue him, even after Kunikida states that they were too short-handed to help Atsushi. In addition, he says to the group of assassins to target only him and that he would snap the necks of anyone who tried to harm his subordinates.
  • Fights Like a Normal: He's an expert martial artist and his ability doesn't help him in combat.
  • Historical In-Joke: Fukuzawa is a powerful figure in Yokohama, and is the first Japanese person Fitzgerald speaks to. The real Fukuzawa was a key figure in the intellectual changes Japan got when it opened up to other countries.
  • Iaijutsu Practitioner: He's frequently seen holding his sword like this and he claims that he can draw it at the speed of sound.
  • Kind Hearted Cat Lover: He likes cats so much that he keeps treats for them in the sleeves of his yukata.
  • Kimono Is Traditional: He is always seen wearing a yukata.
  • The Leader: Of the Levelheaded variety.
  • Living Emotional Crutch: He's the entire reason why Ranpo can act as a functional human being. Before he met Fukuzawa, Ranpo felt disconnected from society because of his extraordinary deduction skills and it was until Fukuzawa told him he was an ability user that Ranpo became comfortable with himself.
  • Parental Substitute: He has an especially close relationship with Ranpo and looks after him like a father figure. Ranpo helped Fukuzawa figure out who killed one of his former clients in the light novel detailing originally how they met. Fukuzawa realised that because of Ranpo's genius this would happen again and created the Agency so that Ranpo would have a place to belong.
  • Perpetual Frowner: Never seen smiling.
  • Power Limiter: What his Ability does. 'All Men Are Equal' can also help his subordinates control their Abilities.
  • The Stoic: Fukuzawa is a serious man and rarely expresses anything but calm authority.



    Atsushi Nakajima 

Atsushi Nakajima

Voiced by: Yuuto Uemura (Japanese), Max Mittelman (English)
中島敦 - 月下獣 note 
Click here to see his full tiger form 
Literary references: He is named after Japanese author Atsushi Nakajima, and his ability is a reference to Nakajima's most famous short story, "The Moon Over the Mountains", in which a man transforms into a tiger.

Age: 18
Height: 170 cm
Blood Type: AB
Birthday: May 5
Zodiac Sign: Taurus
First appearance: Chapter 1/Episode 1

The series protagonist, a orphan who ends up with the agency after being kicked out by his orphanage. Convinced over his life that of being worthless, he dedicates himself to his new friends and comes into conflict with Port Mafia. His ability, "Beast Beneath the Moonlight," allows him to transform into a tiger with regenerative abilities.

  • Accidental Pervert: He and Lucy get their clothes wet after swimming at a dock. Atsushi proposes that Lucy tries to dry their clothes by transporting them to her Pocket Dimension under the instruction that the water in their clothes doesn't transport with them. When Lucy gives it a try, she and Atsushi end up stark naked in Anne's Room since only their bodies were sent there. Lucy freaks out and throws a naked Atsushi back to the water.
  • Adorkable: He flails around adorably as he tries to take Kyouka out to make her feel better.
  • All of the Other Reindeer: He grew up in an orphanage where everyone hated him and he suffered from severe abuse, both verbal and physical, from his caretakers, as well as bullying from the other children.
  • Animal Motifs: His design was also supposed to look like a tiger, with the black and white color scheme and the belt dangling like a tiger's tail. In chapter 13, he also gets Clothing Damage that resembles tiger stripes.
  • Animal-Themed Superbeing: He turns into a tiger.
  • Badass Adorable: Can really give some of the stronger villains a run for their money once he figures out how to control his ability. Doesn't stop him from still being a lovable dork, though.
  • The Berserker: When he transforms into his tiger form.
  • Big Eater: When chazuke is involved, he can pack away bowl after bowl of the stuff.
  • Chronic Hero Syndrome: He just can't turn his back on people he feels to be good inside, risking his life and livelihood on several occasions and handing himself over to the enemy in an attempt to keep his friends from getting hurt.
  • Classical Anti-Hero: He starts out the show as a very unlucky boy with severely low self-esteem because of a very miserable life and lack of control over his ability. He eventually gets better.
  • Combo Platter Powers: He's a were-tiger who happens to also have an amazing Healing Factor ala Wolverine.
  • Comfort Food: Chazuke, a Japanese dish consisting of hot tea/water poured over rice, topped with various savoury foods like seaweed.
  • The Conscience: After Kyouka joins the Agency, Atsushi frequently keeps her most ruthless and aggressive tendencies in check so she doesn't revert to the deadly assassin she was during her time in Port Mafia.
  • Dark and Troubled Past: During his childhood he was shamefully singled out for the most mundane things and then tortured relentlessly for just existing. He is even forced to hammer a nail into his own foot (which he understandably couldn't do, but the Headmaster did it anyway). He was starved, bullied, and beaten until his self-esteem was crushed into fine powder. It's later revealed that the Headmaster did this in hopes of toughening Atsushi in preparation for facing the even crueler real world, that doesn't erase the horrendous childhood Atsushi had. He still obviously suffers from some forms of PTSD and it worsens considerably after his encounter with Q.
  • Desperately Looking for a Purpose in Life: After being told that he was a leech and worthless for all of his life, Atsushi is desperate to find some meaning in his existence.
  • Distressed Dude: As there's a massive reward out there for his live capture, Akutagawa eventually manages to catch him off guard and take him away, but he escapes a few chapters later. He's later captured again by the Guild this time, but freed by Lucy.
  • Doom Magnet: He believes himself to be this (due to having been continously told it when he was a kid) to the point where he thinks his mere appearance causes other people to sacrifice themselves for him. It's unclear how true this is.
  • Fashionable Asymmetry: His unusual haircut.
  • Fingerless Gloves: He often seen wearing black ones.
  • First-Name Basis: Always called by his given name rather than his surname contrary to the typical Last-Name Basis of Japanese culture.
  • Friendless Background: He was raised in an orphanage without love, making it very hard for him to make friends without thinking he'll doom them.
  • Good Thing You Can Heal: He's mutilated, impaled, and torn up throughout the series, only surviving due to his amazing Healing Factor.
  • The Heart: He arguably brings the group together by befriending Dazai and Kunikida.
  • Healing Factor: Part of his Combo Platter Powers, though it only works when he's at least partially in tiger form.
  • Heroic Self-Deprecation: He considers himself a magnet for bad luck and hates himself, believing that he causes calamity wherever he goes, causing him to constantly do good deeds and put others before himself in an attempt to make up for it.
  • Honor Thy Abuser: Upon learning the headmaster of his orphanage was killed by a truck, Atsushi at first thinks he should feel relieved that the man who caused him so much pain and trauma is finally dead. That starts to change when he finds out the headmaster was on his way to congratulate Atsushi for defeating The Guild and saving Yokohama. After learning the headmaster had an abusive past of his own, Atsushi realizes the headmaster likely abused him so badly to prepare him for the harsh life he would lead because of his uncontrollable tiger form and wanted to make Atsushi hate him (the headmaster) instead of himself. Atsushi still doesn't feel he should forgive what the headmaster put him through, but Dazai acknowledges that harsh upbringing was what motivated Atsushi to save people in danger. In the end, Atsushi does shed some tears for his fallen torturer.
  • I Need to Go Iron My Dog: He flusters and excuses himself from Tonan by claiming he has to 'go feed a chameleon' and runs off.
  • I Want Them Alive: People within the Mafia are willing to pay top dollar for his live capture.
  • Innocent Cohabitation: He and Kyoka become roomates after he saves her from Port Mafia.
  • Involuntary Shapeshifting: He unwillingly and unwittingly transformed into a tiger at night before he was able to control his ability.
  • Lightning Bruiser: With his ability activated, he moves way faster than a normal human can track and is a split second blur on security cameras at best. He's also strong enough to rip chunks of concrete out of the floor and toss them like frisbees, while his Healing Factor lets him survive incredible amounts of punishment before going down.
  • Kind Hearted Cat Lover: Cats are listed among his likes. Admittedly, he is a cat himself...
  • Living MacGuffin: There's a massive reward out there for anyone who can capture him alive. According to Fitzgerald, it's because Atsushi's ability is supposedly the key to finding a Reality-Writing Book.
  • Mystical White Hair: He has white hair to match his white tiger form and he's said to have a mysterious connection to the book that can rewrite reality itself.
  • Naïve Newcomer: As the newest member of the Armed Detective Agency, he is unfamiliar with the members of the Agency or how it functions. He also lacks information on the feud between the Agency and the Port Mafia. This requires his colleagues to explain things to him (and to the audience).
  • Nice Guy: He's pitifully nice at times, to the point of putting the lives of complete strangers above his own.
  • Not So Above It All: Is noted to be quite gullible, and very nearly accepted Kenji's way of dealing with a case as normal and acceptable.
  • Oblivious to Love: He fails to realize Lucy has a crush on him despite the blatantly obvious signs of it.
  • Oblivious Transformation: He wasn't aware of his transformations into a tiger, until he ran into some members of the Armed Detective Agency.
  • One Head Taller: He tops Kyoka's height by a head and their relationship gets a lot of Ship Tease.
  • Only Sane Man: Comes off this way sometimes, especially when dealing with his eccentric co-workers.
  • Orphanage of Fear: Grew up in one.
  • Perpetual Poverty: He's usually concerned about his lack of money.
  • Power Incontinence: At first, he has no control over his power and wasn't even able to remember what happened when he transformed. However, he gets over this as he's put into more and more life-threatening situations. It was later revealed that he gained the power to control his ability because he joined the Agency, which meant Fukuzawa was able to suppress it to a controllable level.
  • Red Oni, Blue Oni: The Blue Oni to Akutagawa's Red Oni. Atsushi is calm, meek and gentle, while Akutagawa is violent, ill-tempered and bloodthirsty. This is reflected by how their abilities are visually represented- Atsushi's is blue, Akutagawa's is red.
  • Running Gag: He frequently ends up unconscious in a particular pose, where his head is slumped against the ground, but his butt is sticking up in the air. This gag isn't present in the manga.
  • Scars Are Forever: He has a scar on the left side of his abdomen, caused by the torture he went through at the Orphanage of Fear.
  • Shout-Out: His ability to turn into a tiger is a reference to author Nakajima Atsushi's Sangetsuki/The Moon Over the Mountain, in which the main character loses his touch with reality while following his ambitions of becoming a poet and transforms into a tiger.
  • Skunk Stripe: In the manga, Atsushi has a stripe of black in his otherwise white hair. It eventually fades out. The anime leaves it out, though most of the promo art featuring Atsushi includes it.
  • Spanner in the Works: Dazai is the strong, intelligent and excentric Big Good of the Agency...if he's not wallowing in laziness and suicide attempts. So, when Atsushi comes to the Agency, free from prejudice and sticks with Dazai despite rendering himself as a Doom Magnet, he gives Dazai someone precious to fight for and thus, his motivation. Atsushi basically pulls Dazai from this behavior just by being a nice person.
  • Technicolor Eyes: The upper half of his eyes are purple and the other is yellow.
  • Tomato in the Mirror: The twist in the first chapter/episode is that the white tiger that had been stalking him and got him kicked out of the orphanage was really Atsushi himself.
  • Trademark Favourite Food: Chazuke, a traditional Japanese Comfort Food that consists of tea poured over rice and topped with any number of things that's usually done just to make sure that there's no rice left sticking to the bowl.
  • Unskilled, but Strong: His ability grants him great strength and speed along with a Healing Factor and the benefits of claws and a prehensile tail. However, he has little actual combat experience and thus relies on his wits and observations to get by, but generally resorts to plain old brute force.
  • You Remind Me of X: Seeing a bit of himself in the young boy, in his twisted nature, the Headmaster sought to help Atsushi toughen up by doing unspeakable things to him to make sure he was able to make it out there in the cruel world. Surprisingly, Atsushi did.

Tropes that apply in the BEAST universe

Atsushi was recruited by Dazai to Port Mafia at a young age in place of Akutagawa. He's the infamous "White Reaper" who is completely obedient to his boss Dazai's orders and murders anyone who tries to assassin Dazai.
  • Afraid of Their Own Strength: As painful as the restraints he has to wear are, he's much more afraid of what he could do if he turns into a tiger and attacks people he doesn't want to hurt.
  • The Dreaded: Capable of integrating an overwhelming fear of death even on soldiers with years of experience.
  • Even Evil Has Loved Ones: Calling BEAST!Atsushi evil is a stretch, but he's dangerous and ruthless when performing his job as part of Port Mafia. He still cares very deeply about Kyouka and wants to protect her.
  • Forced into Evil: He kills people because Dazai orders him to and due to his lack of control over his tiger form, he doesn't have much of a choice but to work for Port Mafia.
  • For Want of a Nail: If Atsushi had been found by Dazai some years earlier, Atsushi would be part of Port Mafia instead of the Agency and without Fukuzawa's ability giving him control over the tiger, Atsushi wears painful restraints out of fear he transforms into a tiger and hurts his allies.
  • Friendly Neighborhood Gangster: Despite being a feared member of Port Mafia, this Atsushi is still the same sweet guy of the main series at heart. He had a very friendly conversation with Akutagawa until he discovered he's looking for Dazai's secretary Gin, which makes him an enemy to Port Mafia.
  • Patricide: He killed the headmaster of his orphanage, the closest thing he had to an adoptive father, in a panic when the latter gave him a box which Atsushi thought contained a bomb, but it really was a birthday present.
  • Power Limiter: Because Atsushi never gained control over the tiger in this universe, he's forced to wear painful restraints to prevent turning into a tiger and killing people.
  • Red Baron: He's known as the "White Reaper" as one of the mafia's most dangerous assassins.
  • Sympathetic Murder Backstory: The only time BEAST!Atsushi went against Dazai's orders was when he returned to his orphanage for his birthday. That day, the headmaster gave him a ticking box. Thinking it was a bomb, Atsushi freaked out and killed the headmaster. Afterwards, Atsushi discovered the box contained a clock and a birthday card and he also learned the headmaster had done everything in his power to hide Atsushi's tiger form from everyone. The guilt over killing the man who cared about him like a father is what drives him to carry out Dazai's orders without fail.
  • Trauma Button: Dazai merely mentioning the one and only time Atsushi disobeyed his orders causes Atsushi to freak out so badly he's reduced to a trembling mess cowering in the floor because he's been reminded of the moment he killed the Headmaster.
  • White Hair, Black Heart: White-haired like the Atsushi of the main series, but this one is a ruthless assassin of Port Mafia.

    Osamu Dazai 

Osamu Dazai

太宰治 - 人間失格 note 
Literary references: He is named after Japanese author Shuji Tsushima, who wrote under the pen name Osamu Dazai, and his ability is a reference to one of Dazai's most famous novels, No Longer Human.
Age: 22
Height: 181 cm
Blood Type: AB
Birthday: June 19
Zodiac Sign: Gemini
First appearance: Chapter 1/Episode 1

The first member the Armed Detective Agency Atsushi meets. An extremely strange young man, he hopes to some day find a beautiful woman to commit suicide with. A former member of the Port Mafia, he has a history with Akutagawa and Chuuya. His ability, "No Longer Human," allows him to nullify other abilities through physical contact with either the ability or the user.

  • Above Good and Evil: As observed by Oda, Dazai cares very little for the conventional ideas of good and evil. It is heavily implied that he did monstrous things as a Port Mafia executive, yet he treats cruelty as nothing but a means to an end instead of something he actively participates in for his own pleasure. He also has no problem pulling a complete Heel–Face Turn and fully dedicating himself to the cause of 'helping people' once Oda urged him to become a better person, even if he still uses somewhat questionable (but far less brutal) ways of achieving his plans.
  • Animal Motifs: He is commonly associated with foxes in the franchise, as he is smart, cunning but also kind of lazy. He was dressed as a Kitsune in one Youkai related merch and this official Haregi artwork also shows him with a fox. The depiction of foxes differs greatly depending on culture - from benevolent messengers and tricksters to being murderous and manipulative, a juxtaposition that much resembles Dazai himself. In this official art, he is shown wearing a traditional kitsune head mask.
  • Anti-Hero: Bordered on outright sociopathic prior to meeting Oda. While he's gotten better post Heel–Face Turn, he still has his moments.
  • The Atoner: Shows shades of this, though whether he genuinely regrets the things he did as a member of the Mafia or simply wants to distance himself from his past for Oda's sake is left ambiguous.
  • Badass in a Nice Suit: During his mafia days.
  • Badass Longcoat: He wears a long trench coat and we already know that he's badass.
  • Bandage Babe: They cover most of his body, and it's unknown what, if anything, they're covering up.
  • Bandaged Face: When he worked for Port Mafia, he wore bandages over his right eye.
  • Big Brother Mentor: He's the closest to Atsushi and is willing to help him however he can.
  • Blessed with Suck: His ability is most useful in combat situations, but it's always active except in very specific extreme circumstances, which means Dr. Yosano can't easily heal him using her ability if he gets too banged up.
  • Boring, but Practical: His ability isn't very flashy, dramatic, or interesting compared to the abilities of his colleagues in the Agency and former colleagues in the Mafia, but it's extremely useful in fights, has few known drawbacks, and allows his allies with dangerous or hard-to-control abilities to make more effective use of them.
  • Breakout Character: Is by and far away the most memorable and well-liked character in the franchise for his quirky personality, mysterious past, and cool ability, appearing in even more promotional material than Atsushi, the protagonist. Both seasons 2 and 3 of the anime spend a third of their runtime animating prequel light novels focusing on Dazai's time in the Port Mafia (season 2 on his final days before his defection and season 3 covering how he first met Chuuya). His namesake being popular also plays a part in this.
  • Brilliant, but Lazy: Not as bad as Ranpo, but good luck getting him to actually do his paperwork.
  • Broken Ace: Whenever he actually gets to do something, he's smart, talented and strong, and there aren't many people who at least begrudgingly accept him. He is also a Stepford Smiler who tortures himself with the memories of his past failures and his lost friend.
  • Bunny-Ears Lawyer: Despite his odd hobbies, Dazai is actually a very competent detective. His deductive abilities aren't too shabby and he possesses an extremely useful ability that gives him an advantage against other ability users.
  • Captured on Purpose:
    • He deliberately gets captured by Kyouka so he can look for the archives of Port Mafia and find out who offered the money for Atsushi's kidnapping.
    • He lets the Hunting Dogs arrest him so he's sent to the same top secret prison Fyodor is currently at with the intention of keeping an eye on Fyodor's movements.
  • Cheshire Cat Grin: Dazai rarely stops smiling, and his smiles get very unsettling in serious or darker moments, frequently also dipping into Psychotic Smirk territory.
  • The Chessmaster: Purposely manipulated events so to ensure a new duo of Atsushi and Akutagawa would rise to eventually combat an evil (implied to be Dostoyevsky.
  • Child Prodigy: Was the youngest person in Port Mafia history to become an Executive.
  • Chivalrous Pervert: Seen flirting with women on multiple occasions, although he does this by offering to commit double suicide with them. He's never less than a gentleman though.
  • Cloudcuckoolander: Dazai is a rather eccentric man that enjoys researching and trying out various suicide methods for fun.
  • Curtains Match the Window: He has dark brown hair and eyes.
  • Death Seeker: Maybe. Played straight during his mafia days. He is said to have grown bored of the world, and is seeking out something that could defy his expectations and hopefully kill him in the process. It is ambiguous whether he still thinks that way or not after leaving the mafia, but his proclamations of suicide since joining the detective agency have been a lot more lighthearted when compared to his genuine desire for death in the mafia, and happen less and less often as the series goes on. Crosses over a lot with Desperately Looking for a Purpose in Life.
  • Drives Like Crazy: The first light novel shows that Dazai is a terrible driver.
  • Dull Eyes of Unhappiness: An interesting spin on this. There is confirmation that Dull Eyes of Unhappiness indicate a villain. Dazai is a good guy, but his eyes tend to cloud over now and then. For example, when he is pointing out Mori's Klingon Promotion, his eyes are magnificently dead. Notably, when he was in the mafia, his eyes were almost permanently like that, except when talking to Odasaku.
  • Fights Like a Normal: Dazai himself doesn't fight much, preferring to stay on the backlines providing tactical support, but his ability inflicts this on enemies who rely on their combat-enhancing abilities.
  • The Gadfly: He likes providing "useful tips" for Kunikida only to say that he's messing with him. He also likes needling his former partner, Chuuya.
  • Good Costume Switch: Trades in his black suit and coat for a beige trench coat and khaki slacks when he quits the Mafia.
  • Good Is Not Nice: He's generally upbeat and personable and dedicated to helping people, but has warped views on ethics and morality and tends to take a pragmatic approach to the cases he works on.
  • Guile Hero: His areas of expertise are strategy and reading people, and he used to specialize in interrogation when he was in the Mafia. As a result, blackmail and manipulation are some of his favorite tactics.
  • Heel–Face Turn: Formally was an Executive of the Port Mafia, now a member of the Armed Detective Agency. He quit the Mafia after Oda's death and began trying to improve himself out of a desire to honor Oda's memory and final wishes.
  • Hidden Depths: Dazai generally presents himself a lazy and carefree man who prefers to push his paperwork off on others, but he's extremely knowledgeable about Yokohama's criminal underworld, exhibits Chessmaster tendencies, and can be surprisingly poignant at times.
  • Historical In-Joke: More than any character, Dazai has a habit of attracting these:
    • His Death Seeker habits are an obvious reference to RL!Dazai's multiple suicide attempts. Dazai is even introduced attempting to drown himself (the way RL!Dazai successfully did himself in) and his wish to die with a beautiful woman is a nod to attempting suicide twice with a lover (one of which being the successful attempt).
    • Dazai is implied to have been brought into the Port Mafia from a young age and left because of personal reasons. In real-life, Dazai was the son of a rich family, and was ultimately disowned due to his political leanings.
    • Dazai mentions at one point to having done a rather disturbing self-portrait, which is a Shout-Out to No Longer Human, where the narrator (a blatant Author Avatar) does the exact same thing.
    • His relationship with Ango and Odasaku is a nod to the Buraiha, a group of authors dissatisfied with the then-current Japanese government.
  • Improbable Age: Dazai was considered for the position of Port Mafia executive before he was 16.
  • Jerkass: Maybe. As Akutagawa's mentor, he beat the younger man frequently. He doesn't hesitate to taunt Akutagawa with the fact that he (Dazai) has never seen him as strong, knowing how sensitive Akutagawa is to that particular topic. It could be a case of Tough Love instead, though.
  • Let's Get Dangerous!: He's eccentric, lazy, and is depicted in a Super-Deformed art style in the anime more often than any other major character, but he's also highly competent at his job when the situation calls for it or things get serious, and stops teasing Kunikida whenever the two are at an important point in a case.
  • Logical Weakness: No Longer Human requires Dazai to make physical contact, so it's ineffective against abilities that don't have a physical form if he can't get close enough to touch the user. Obviously it also does nothing against opponents who don't have an Ability. Lastly, it's always active as long as there's blood flow in his brain, so Yosano's healing Ability can't effect him, except in a very small time frame in extreme circumstances.
  • Manipulative Bastard: He's not above manipulating his own coworkers if it means accomplishing his goal.
  • Mysterious Past: He's introduced as being a man with an unknown past who's quickly revealed as a former Port Mafia member. While the second light novel gave a number of details, much of his life prior to meeting Oda is still shrouded in mystery.
  • Obfuscating Stupidity: He may not seem like the brightest bulb at first, but he's one of the smartest members in the agency. For example, despite not being a deductive genius like Ranpo, he manages to figure out a good chunk of the murder mystery in episode 5 on his own.
  • Odd Friendship: Is Vitriolic Best Buds with Kunikida, the stern, idealistic Control Freak.
  • O.O.C. Is Serious Business: Drops his perpetual smile when Higuchi tells him that Mori's released Q from his confinement.
  • Peek-a-Bangs: Back in his days as a member of the Port Mafia, he kept his bangs over the bandaged right side of his face.
  • Perpetual Smiler: He's generally seen with a smile on his face, in stark contrast to his partner Kunikida.
  • Photographic Memory: His memory capacity is inhuman.
  • Pointless Band-Aid: He had an adhesive bandage on his left cheek when he was part of Port Mafia.
  • Power Nullifier: No Longer Human allows him to nullify other people's powers.
  • Pragmatic Hero: He tends to take a very "means to an end" approach to his job and is the Agency member most willing to get their hands dirty if it means solving a case or getting crucial information.
  • Reformed Criminal: Dazai used to be one of the most dangerous and feared men of Port Mafia. After the death of his best friend Odasaku, he abandoned the life of organized crime to pursue a job where he could help people in need at Odasaku's dying request.
  • Rescue Introduction: Dazai first appears drowning at a river and Atsushi jumps in to pull him out. Instead of thanking his savior, Dazai complains about his suicide attempt being ruined. Doubles as Interrupted Suicide.
  • Suicide as Comedy: How his constant talk about suicide is played. It's especially morbid given he's named after an author who drowned himself.
  • Sociopathic Hero: An Above Good and Evil Manipulative Bastard ex-mafia Anti-Hero with the closest thing to a moral compass being a friend's dying request.
  • Sour Outside, Sad Inside: In his mafia days, he appears to be an arrogant loner who seems to be treating everyone but his friends like shit in order to intimidate them. That is, until he breaks down when Odasaku loses the orphans and decides to go alone into Mimic's base. He reveals that he adapted this persona to cope with the life in the mafia. In the ADA, this turns into...
  • Stepford Smiler: ...this. Behind his laziness, benevolent smile and optimism, Dazai is someone who is still very damaged by what happened in his younger years. He is on bad terms with Mori, who he holds responsible for it, and his appearance is the foremost happenstance when his smile turns into a Slasher Smile. This behavior matches the protagonist of No Longer Human to the letter.
  • Took a Level in Cheerfulness: He was closer to being The Stoic before he left Port Mafia, in sharp contrast to his lively and playful personality as a member of the Agency.
  • Torture Technician: His specialty in his Mafia days was interrogation and he bragged to Kouyou before questioning her about the Mafia's interest in the Guild that there wasn't anyone he couldn't get to spill everything.
  • Tough Love: Maybe? While his treatment of Akutagawa is pretty horrible, it may have been Dazai's way of toughening him up to become a respected member of the Port Mafia, and to better himself.
  • Vitriolic Best Buds: With Kunikida. Most of their interactions involve Dazai messing with Kunikida, and Kunikida throttling him. They still manage to work well together despite this.
  • Weak, but Skilled: Described more or less as such by Chuuya. He's a piss-poor martial artist for an ex-mafia, but he's good at strategizing and his ability makes him indispensable in fights.
  • We Used to Be Friends: Has this kind of relationship with Ango over Ango's role in the Mimic incident, and is hinted to have this kind of relationship with his former partner Chuya.
  • What, Exactly, Is His Job?: Before everyone figured out he used to work for the Mafia, it was a game among the Agency members to try to figure out what Dazai's old job was.
  • Young and in Charge: He was the youngest Port Mafia executive in mafia history.

Tropes that apply in the BEAST universe

In a parallel universe, Dazai never left Port Mafia and succeeded Mori as the boss after he was killed by Mimic.
  • The Don: He took over Port Mafia after Mori died during the Mimic incident. With him as the leader, Port Mafia's influence spans even greater than Mori's influence managed.
  • Driven to Suicide: The BEAST novel ends with Dazai throwing himself off the ledge of the main Port Mafia building because he told Atsushi and Akutagawa to protect the Book and there can't be more than two people who know the true power of the Book.
  • Go Out with a Smile: Dazai jumps from the Port Mafia's building with a smile on his face, knowing Odasaku is alive and will publish his novel even though Dazai won't be able read it.
  • Love Makes You Evil: Because of remembering other timelines, Dazai loves Odasaku as his best friend even though they have never even spoke to each other in the BEAST universe. Dazai wants to give Odasaku the happy life that he can't get in any other timeline so badly that he manipulated the lives of everyone around him, separated the Akutagawa siblings and made Atsushi and Kyouka go through hell by following the commands of Port Mafia.
  • Poisonous Friend: The BEAST universe is basically Dazai becoming the most feared Port Mafia boss ever and making Atsushi's life hell for the sake of creating a timeline in which his best friend Oda doesn't die tragically, even though Dazai and Oda are complete strangers in the BEAST timeline.
  • Ripple Effect-Proof Memory: Because of his nullification ability, the reality-altering power of the Book doesn't affect Dazai in the same way as others and he has the memories of several timelines.
  • Suicide for Others' Happiness: In the BEAST novel, Dazai does everything in his power to create a timeline where Odasaku lives and can write his novel. After entrusting Atsushi and Akutagawa to protect the Book so this timeline doesn't disappear, Dazai kills himself.

Doppo Kunikida

Voiced by: Yoshimasa Hosoya (Japanese), Patrick Seitz (English)
国木田独歩 - 独歩吟客 note 
Literary references: He is named after Japanese author and poet Tetsuo Kunikida, who wrote under the pen name Doppo Kunikida, and his ability is a reference to Doppo's Poetry, a compilation of some of Kunikida's poems.
Age: 22
Height: 189 cm
Blood Type: A
Birthday: August 30
Zodiac Sign: Virgo
First appearance: Chapter 1/Episode 1

Dazai's partner. A straight-laced man who manages most of the Agency's operations. His ability, "Doppo's Poetry"note , enables him to create anything he writes down in his notebook, as long as he understands the object's form and function and it's smaller than the notebook.

  • An Arm and a Leg: He has both of his arms amputated after his last ditch effort to defeat the Hunting Dogs by himself.
  • Badass Baritone: Courtesy of Yoshimasa Hosoya and Patrick Seitz.
  • Big Good: He's the in-charge manager of the Agency. Fyodor's (and the Hunting Dogs') strategy is basically to render him immobile by provoking him psychologically so they don't have to fight him, as fighting against someone who manages the daily business of the local Badass Crew is just asking for the entire city to hunt them down.
    Ranpo: Kunikida, you’re the strongest and most virtuous of us in the Agency. That’s why the enemy tried to break you first.
  • Childhood Friends: He's stated to have been friends with Katai for ten years. Given that they're in their early twenties, it means that they first met when they were in middle school.
  • Control Freak: Kunikida does not like it when his carefully laid out plans are disrupted, especially by Dazai.
  • Crazy-Prepared: His ability is effectively a weaponized superpower version of this.
    • He also gets around his ability's main Logical Weakness by carrying around slips of paper with the names of objects he frequently creates already written down.
  • Curtains Match the Window: He has blond hair and yellow eyes.
  • Early Installment Weirdness: Early into the series, he states he was a math teacher before becoming part of the Agency. This was retconned later to a part-time job as an algebra lecturer when it was insinuated that he was one of the early members of The Agency and most likely joined as a teenager.
  • Expressive Hair: In the anime, his ponytail becomes a jagged zig-zag when he's particularly angry.
  • Fights Like a Normal: His ability isn't combat-oriented and he uses it to create conventional weapons, like pistols and stun guns, to supplement his martial arts skills.
  • Heroic BSoD:
    • For comedic effect when he finds out Dazai used to work for the Mafia.
    • Played for drama when Kunikida is forced to kill a child in order to save a crowded passenger train. Fyodor takes advantage of this later and invokes another BSOD on Kunikida by influencing a child to kill himself in front of Kunikida's eyes.
  • Hot-Blooded: Kunikida has a very bad temper and is always shouting at the top of his lungs. Especially when he is angry with Dazai's suicidal antics.
  • Improbable Age: Stated early on to have been a math teacher prior to becoming a detective, later retconned into a part-time side job as an algebra lecturer after it was implied he joined the Agency in his mid-late teens, which is still a bit unlikely for a 22-year-old.
  • Jerk with a Heart of Gold: Kunikida is, at best, gruff and stern to his fellow detectives and Atsushi. He's not very tolerant of disruptions to his plans and doesn't like those who would disturb his carefully laid schedules (AKA Dazai). That said, he is actually a very idealistic man that strives to live up to his own expectations. He will do anything he can to complete a mission and protect his colleagues.
  • Knight In Sour Armor: Although rather grumpy and cynical in disposition, Kunikida will always try to do the right thing according to his ideals.
  • Logical Weakness: He can't use his power if he's separated from his notebook, he runs out of pages, or his hands are restrained or cut off.
  • Megane: Wears a pair of black-framed glasses.
  • My Greatest Failure: Blames himself for the death of 5 detectives in the Azure King incident. Kunikida provides Rokuzou, the hacker son of one of the detectives, with jobs and looks out for him out of guilt.
  • Not So Stoic: Despite being the first to remind his coworkers that it's often not feasible to save everyone, he's deeply uncomfortable when a mission involves casualties and is visibly shaken by the resolution of the Azure Messenger incident.
  • Number Two: Of the Armed Detective Agency. He handles the day-to-day minutiae of running the Agency, with the President only making rare appearances. It is explicitly stated at one point that the next director of the Agency will be Kunikida because he has all the qualities to do so. He's named acting president by the rest of the Agency when Fukuzawa is put into an ability-induced coma.
  • Odd Friendship: Is Vitriolic Best Buds with Dazai, the cheerful former Mafia executive.
  • Only Sane Man: At times. He is mostly intolerable to the other characters quirks, such as Dazai's constant suicide attempts.
  • Perpetual Frowner: In contrast to Dazai, Kunikida is usually seen frowning.
  • The Power of Creation: He can create any object by writing it's name in his notebook, as long as he understands the object's form and function and it's smaller than the notebook.
  • Pragmatic Hero: As the most logical member of the Agency, Kunikida is usually the one to consider what's most practical for any given situation. As such, his assessments can be rather cold-hearted at times. For example, he tells Atsushi to hand Kyoka over to the police, stating that her status as a wanted murderer would sully the Agency's reputation. When Atsushi protests, Kunikida asks Atsushi if he has the resources to protect Kyoka, suggesting that Atsushi should be more worried about himself.
  • Reality-Writing Book: Thanks to his ability, his notebook is a minor type 3 example. His ability, Doppo's Poetry, allows him to create objects by writing them down in his notebook, as long as the object he's trying to create is smaller than the notebook.
  • Sadistic Choice: Fyodor manipulates events to put him in a situation where he has to choose between saving an innocent child with bombs strapped around her neck or a train full of passengers.
  • Stoic Spectacles: Kunikida is professional and likes to organize and schedule every little detail to the point that it becomes a Running Gag. He also has the long hair and the ponytail.
  • Team Dad: Kunikida acts the part of a stern and grumpy father to his friends in the Agency, particularly evident in his interactions with Atsushi and Dazai. Kunikida scolds and yells at them for small things all the time, but he's always looking out for them.
  • The Leader: While he is not officially the leader of the Agency, when trouble occurs making Fukuzawa unable to be leader, he is often the appointed leader, due to his intelligence and sensibility.
  • Vitriolic Best Buds: With Dazai. Most of their interactions involve Dazai messing with Kunikida and Kunikida throttling him. They still manage to work well together despite this.
  • Western Zodiac: A Virgo, and a textbook example of one.
  • Writers Cannot Do Math: A victim of this. He somehow found time to go to university, study to become a maths teacher, work as one for a while, and then work for two different law enforcement agencies. He's only 22 years old.
  • Younger Than He Looks: Despite what his appearance and behavior imply, he's actually 22, making him a good four years younger than Ranpo and Yosano.

    Ranpo Edogawa 

Ranpo Edogawa

Voiced by: Hiroshi Kamiya (Japanese), Vic Mignogna note , Landon McDonald note  (English)
江戸川乱歩 - 超推理 note 
Literary references: He is named after Japanese mystery author Tarou Hirai, who wrote under the pen name Ranpo Edogawa.
Age: 26
Height: 168 cm
Blood Type: O
Birthday: October 21
Zodiac Sign: Libra/Scorpio cusp
First appearance: Chapter 1/Episode 1

An intelligent and highly praised member of the Agency. He's well-known for his amazing deduction abilities, which he often uses to help the police solve crimes. Convinced that he has an ability that he calls "Ultra Deduction," but he really doesn't.

  • Ambiguous Disorder: Several aspects of Ranpo's character highly suggest he has some manner of disorder even though whether he has one is never made explicit. He's a genius detective with nearly superhuman observation skills. He also needs someone to accompany him everywhere he goes because he doesn't know how to use the train or the bus, is exceedingly childish for his age and refuses to do common tasks he deems "too bothersome" for him. Before Fukuzawa took him in, he could neither understand social norms nor get along with other people, causing him to be kicked out of every job he got, and gradually became severely disconnected and isolated from humanity.
  • Badass Normal: Unlike the rest of the Agency he doesn't actually have an ability and thus gets by with his amazing skills of deduction and observation.
  • Blackmail: He gets Mushitarou to turn himself in and undo his evidence-destroying ability that he used to frame Kunikida by threatening to reveal the last page of the manuscript of his murder victim to the public, which Mushitarou can't allow because the authorities would find the tears he shed over the paper when he aided in his friend's suicide.
  • Brilliant, but Lazy: When not on a case, he's usually seen lounging around the office eating something sweet. When Atsushi is taken by Akutagawa, the Agency president needs to bribe Ranpo in order to get him to figure out where Atsushi had been taken.
  • Bystander Syndrome: When Atsushi is kidnapped by Port Mafia, Ranpo insists the Agency has no reason to save Atsushi since they're not his bodyguards and they should have more important jobs to do. Even after Fukuzawa orders the Agency to make saving Atsushi their top priority, Ranpo refuses to cooperate until Fukuzawa bribes him with praise.
  • Cerebus Retcon: His delusion over having an Ability is revealed in the third novel to have a much darker backstory behind it. Twelve years before the series began, Ranpo was an orphaned Teen Genius who Fukuzawa met when he solved the murder of Fukuzawa's client. Ranpo's deduction abilities however caused him to become severely disconnected, isolated from humanity and he was on the verge of a mental breakdown. "Super Deduction" was a lie Fukuzawa created to enable Ranpo to continue.
  • Clear Their Name: The Perfect Crime arc starts with Ranpo looking for a way to prove Kunikida's innocence after he has been framed for the death of the little girl that was tricked into blowing herself up by Fyodor.
  • Eyes Always Shut: Unless he's surprised or using his 'ability'.
  • First-Name Basis: Usually referred to by his given name.
  • Foreshadowing: His 'Ability' is the only one note  that's not named after a work of the author he's called after. When there came a sort of Defictionalisation, and Kadokawa put the likeness of the BSD characters on the books of the real authors, Murder On D Hill (D坂の殺人事件, D-zaka no Satsujin Jiken) was chosen for Ranpo, after chapter/episode 6.
  • Genius Sweet Tooth: The smartest character in the show and in all of his appearances in the anime so far, he has been seen eating or drinking something sweet.
  • Great Detective: He is known as one of the best detectives there are and he's proud of it.
  • Historical In-Joke: His relationship with Poe in the series is basically the reverse of their namesakes- the real Ranpo Edogawa greatly admired the real Edgar Allan Poe, to the point of basing his pen name off of Poe's name ("Edogawa Ranpo" is derived from the Japanese pronunciation of "Edgar Allan Poe").
  • Idiot Savant: He's a brilliant detective capable of solving crimes in an instant, but can't figure out how to use the train for some reason.
  • Insufferable Genius: He's not exactly humble about his talents.
  • Intelligence = Isolation: When he was younger, Ranpo knew his deduction skills made him different from others and he felt alienated to the point the only way Fukuzawa could help him continue functioning was to tell him a lie about his genius being the result of an Ability.
  • It Was a Gift: His glasses were a gift from Fukuzawa.
  • It's All About Me: Frequently prone to wondering aloud why no one is focusing on him. Doubles as Attention Whore.
  • Jerk with a Heart of Gold: He gives the impression of being a lazy, rude and arrogant smartass, but he's incredibly loyal to Fukuzawa and his friends.
  • Magic Feather: His naturally uncanny aptitude allows him to solve seemingly impossible mysteries but he needs to use a pair of glasses to "activate" this ability.
  • Manchild: While he's a genius detective in his mid-twenties, Ranpo is usually very childish and throws tantrums when asked to do things he finds too bothersome, causing others to compare him to an elementary schooler.
  • Manipulative Bastard: When he finds himself unable to logically turn Mushitarou in due to lack of evidence (which he always needs), he forces Mushitarou to do so by pointing out that if he doesn't do that, the greatest thing he cares about (the mystery of his friend Yokomizo), would be forfeit. This is explicitly likened to what Fyodor does.
  • Nice Hat: He dons a deerstalker hat to give him a classical detective look.
  • Nominal Hero: He'll pretty much only do work if he's bored out of his mind or Fukuzawa bribes him with praise, and he doesn't really care one way or the other how things go as long as he and Fukuzawa are safe.
  • Non-Action Guy: Is never seen fighting, probably because he can't.
  • No Sense of Direction: Needs a guide to get home after solving a case. He also can't figure out how to use the train.
  • Oh, Crap!: Has a massive Oh, Crap! moment when he figures out Fukuchi is Kamui while right in front of him, and at his mercy.
  • Older Than He Looks: Ranpo doesn't look any older than his eighteen-year-old coworkers Atsushi and Tanizaki. He's 26 years old, making him the oldest agent of the Agency.
  • Only Friend: Ranpo becomes this to Poe after their encounter in the Guild arc. Poe mentions no one ever calls him except for Ranpo.
  • O.O.C. Is Serious Business: Loses his normal cheerful arrogant attitude once the need to find the culprit who by Fyodor's command puts Fukuzawa and Mori in a coma that will result in their deaths within 48 hours if either of the other party isn't killed, which is noted by Atsushi.
  • Pragmatic Hero: After the Cannibalism arc, Ranpo is willing to use any dirty trick he needs in order to protect his comrades, even if it means becoming a cunning demon like Fyodor.
  • Protagonist-Centered Morality: Exemplified by his motto, "all's well that's well for me!"
  • Sherlock Homage: A Great Detective who can solve cases in an instant through Sherlock Scans, wears a deerstalker hat and an inverness cape, and is an Insufferable Genius with an Ambiguous Disorder.
  • Sherlock Scan: His "ability." He can quickly scan a crime scene and deduce exactly what happened in a matter of seconds. He can also quickly piece together the solution to nearly any problem, puzzle, or mystery, as long as he has some kind of lead.
  • Shorter Means Smarter: He's the second shortest male member of the Agency and one of the most intelligent characters in the series.
  • The Smart Guy: The smartest member of the Agency and the only one who can do real detective job in the matter of seconds.
  • Smart People Wear Glasses: He puts on a pair of glasses when he uses "Ultra Deduction". He believes this is what activates his "ability".
  • Spell My Name with an "S": Sometimes his first name is romanized as "Rampo".
  • Super Intelligence: Of the exceptional perception and advanced reasoning varieties.
  • The Team Normal: The only member of the Agency to be a normal human with no ability. His "Ultra Deduction" still makes him one of the most valuable additions to the team.
  • "Well Done, Son!" Guy: Receiving Fukuzawa's praise is one of the few things that motivate Ranpo to work.

    Akiko Yosano 

Akiko Yosano

Voiced by: Yu Shimamura (Japanese), Erica Lindbeck (English)
与謝野晶子 - 君死給勿 note 
Literary references: She is named after Japanese poet Akiko Yosano, and her ability is a reference to Yosano's poem "Thou Shalt Not Die."

Age: 25
Height: 166 cm
Blood Type: O
Birthday: December 7
Zodiac Sign: Sagittarius
First appearance: Chapter 1/Episode 1

The Agency's medic. Her ability, "Thou Shalt Not Die," allows her to heal anyone who has received a life-threatening injury.

  • Adaptational Skimpiness: During Yosano's "medical treatments" on Tanizaki and Atsushi in the anime, she takes off her shirt as Sexophone music plays in the background.
  • Action Girl: The most qualified for this title out of the Detective Agency's women.
  • Animal Motifs: She's associated with butterflies, mainly related to the themes of death and resuscitation of her ability.
  • Bag of Holding: Her doctor's bag shouldn't be able to hold half of the weaponry she stuffs into there, which include a hatchet blade as long as her arm!
  • Because You Were Nice to Me: The reason why she's so attached to the Agency. Fukuzawa and Ranpo saved her from being used as a tool for war by Mori again. Ranpo also assured Yosano the Agency wouldn't abuse her ability like Mori did and they understood how much grief she suffered from seeing so many men die in the war.
  • Berserk Button: Do not treat death lightly. As a doctor, she's seen many people die because she was unable to save them. People that treat death like a game, like Motojiro Kajii, inspire her wrath.
  • Blessed with Suck: Her ability can heal any injuries, but it doesn't work unless the person is at the brink of death. While it isn't played as seriously in the present plotline, her backstory shows this trope in full extent. Mori exploited her power by having Yosano heal the soldiers of a military troop. The soldiers were almost killed every day and weren't allowed to retreat because of Yosano healed them every time. Yosano came to blame herself for trapping the soldiers in a Fate Worse than Death.
  • Chainsaw Good: Her preferred method of harming her injured coworkers to the point where she can heal them with her ability is to shackle them to her examination table and then introduce their torso to a chainsaw. On the other hand, in a notable example of writers doing their homework, Yosano doesn't try to fight with one (but does use it to intimidate people, which proves to be pretty effective).
  • Combat Medic: She may be a doctor, but she's no stranger to violence. She kicks Motojiro Kajii's ass after fooling him into thinking that she was dead.
  • Dark and Troubled Past: When she was 11 years old, Yosano was recruited by Mori as the medic for a small military base where the soldiers were fatally wounded every day. Yosano could always heal their physical injuries, but she could do nothing about their emotional and mental traumas. To make it worse, the soldiers weren't allowed to retreat the battlefield because Yosano was there. Eventually, Yosano wanted to stop healing them to end their suffering, but Mori wouldn't let her. Yosano finally had a breakdown when a soldier she was fond of hanged himself.
  • Deadly Doctor: She doesn't kill people with her medical expertise, but the nature of her ability frequently requires her to injure her patients. To that end, she carries around a doctor's bag filled with weapons.
  • The Dreaded: Hilariously enough, to her own colleagues. She's a valued member of the Agency, but her colleagues dread being injured because it means that they'll have to be treated by her. Treated far more tragically as part of her Dark and Troubled Past, where she was sent to the battlefield to constantly heal soldiers' injuries so they can be sent out into the field. While she could heal their physical wounds, the mental scars from the grievous wounds they suffered remained, sending them all into delirium from being sent into battle and nearly dying over and over. Several of them committed suicide to escape her and they branded her the "Angel of Death".
  • Fights Like a Normal: Her ability gives her the freedom to fight recklessly and try more aggressive tactics, but it doesn't enhance her combat skills beyond that. Any fighting she does is purely her own skill. Noticeably, she can swing her hatchet hard enough to smash the ground during her fight with Kenji against Chuuya.
  • Harmful to Minors: Yosano's backstory has her exposed to the horrors of War Is Hell when she was a medic to a small army at only eleven years old.
  • Heal the Cutie: Yosano was a plucky 11-year-old girl who worked in a candy store until Mori took her to work as a military medic. She accepted the work because she wanted to use her power to save lives. What Yosano didn't know was that she was being used as a tool for a project to create an "immortal army". Slowly, the young Yosano was traumatized by seeing the soldiers getting fatally wounded and killed every day, feeling guilty because her healing power was the reason why they couldn't retreat. Eventually, a soldier she was attached to committed suicide, which caused Yosano to have a mental breakdown. As if the poor girl haven't suffered enough, Mori intended to force her into using her Ability to start a war against Port Mafia so he could take it over. The one who saved her from going through that hell again was Fukuzawa who took her into the Armed Detective Agency to keep her away from Mori's reach. Young Yosano was still terrified that using her healing Ability would only bring endless suffering and death to those she wants to save, but unlike the coldhearted Mori, Ranpo sympathized with Yosano's pain and knew that she was so sad because she didn't want any of those soldiers to suffer more than they needed to. It was then that Yosano was sure that she was being taken in by people who do care about her as a person instead of only wanting to take advantage of her Ability and that helped heal her broken spirit.
  • Healing Hands: She can heal herself and others, but only if on the verge of death. If her patients are only slightly injured, then she needs to hurt them more until they're half-dead.
  • Healing Shiv: Her "treatments" usually consist of hacking away at her patients until they're on the verge of death before using her ability to heal them.
  • I Let Gwen Stacy Die: A soldier she liked committed suicide after being sent to the frontlines and almost killed every day because Yosano continued to heal him. Yosano shut down from the guilt until Fukuzawa and Ranpo took her in.
  • Improbable Weapon User: In the opening animation of the anime's first season, she is shown wielding scalpels...which she doesn't even wield like that in the anime or in the manga. But who does use scalpels that way? Mori.
  • Labcoat of Science and Medicine: Not part of her usual outfit, but she does don a labcoat in the story Poe writes.
  • Old Friend: Is hinted that she has this relationship with Mori, of all people. In real life, Yosano Akiko and Ougai Mori were in the same poetry group, and she even asked him to name her twin daughters.
  • Please Kill Me If It Satisfies You: In chapter 68, Michizou Tachihara reveals himself as the younger brother of the soldier who was Driven to Suicide after being healed by Yosano too many times. He also reveals he's the fifth Hunting Dog and infiltrated Port Mafia to eventually take his revenge against Yosano for "killing" his brother. Once she hears this, Yosano does nothing to defend herself as Tachihara points a gun at her and tells him to do as he must.
  • Precocious Crush: When she was eleven, she had a crush on an older man who made her butterfly hairpin. It didn't end well; the man hanged himself while blaming Yosano for healing him to be sent back to the frontlines of an unwinnable war over and over again.
  • Red Baron: She was once known as the "Angel of Death" for her ability to constantly bring soldiers from the brink of death. But since she couldn't erase the memories of the wounds they suffered, all of her patients went insane from being sent into battle over and over after suffering any number of horrible wounds.
  • Sadist: Played for laughs. Yosano seems to enjoy inflicting additional injuries to her patients.
  • Sexy Spectacles: Again, she doesn't wear them usually, but she wears glasses in Poe's story. Ranpo uses them after her in-story death to activate his Ultra-Deduction.
  • They Died Because of You: Michizou Tachihara blames Yosano for the tragic death of his older brother who was Driven to Suicide because of Yosano's healing ability forcing him to continue fighting in an unwinnable war.
  • Thou Shalt Not Kill: While she has no problems with grievously maiming her opponents (and allies) due to the nature of her ability, she refuses to let anyone die on her watch.
    Yosano: No matter how hard we doctors try, our patients still slip through our fingers. Death, the ultimate form of science? What a load of crap! I'll kill anyone who doesn't value life!
  • Tragic Keepsake: Her golden butterfly hairpin was made for her by a soldier she healed during her time as the medic of a military station. That soldier hanged himself after she brought him back from the brink of death far too many times.
  • Trauma Button: She freezes up at the sight of the dog tag that belonged to the soldier who killed himself after he broke from being kept in an unwinnable war by her healing ability.
  • '20s Bob Haircut: Even though this series isn't set in the '20's, she has the aesthetic, including the haircut.
  • Unwitting Pawn: When she was younger, Yosano was used by Mori to create an "immortal" army by having her heal soldiers to send them back to the battlefield over and over again until their minds broke. Yosano had thought she had been brought there to save lives and it was too late when she realized her Ability had condemned those soldiers to a Fate Worse than Death.

宮沢賢治 - 雨ニモマケズ note 
Literary references: He is named after Japanese poet and children's author Kenji Miyazawa, and his ability is a reference to Miyazawa's poem "Undefeated by the Rain."
Age: 14
Height: 158 cm
Blood Type: O
Birthday: August 27
Zodiac Sign: Virgo
First appearance: Chapter 1/Episode 1

A cheerful and easygoing boy from the countryside. His ability, "Undefeated by the Rain," gives him super-strength when he's hungry.

  • Animal Motifs: He's often associated with a cow, because his favorite animal is a cow, he's strong but has yet to show if he's smart, stubborn and capable of great violence but is actually soft-hearted.
  • Badass Adorable: He'll pick up cars and chuck them at you while wearing a cute, innocent smile the entire time. In chapter 38, he rips a steel door out of the wall with a :D expression.
  • Care-Bear Stare: More or less how he solves his cases.
  • Country Mouse: Hails from the countryside, which can make him rather naive to several urban concepts. He doesn't really understand things like money and usually relies on his country instincts.
  • Does Not Like Shoes: Usually goes around barefoot, although he does wear sandals at times.
  • The Dreaded: Justifiably so, the terror he brings when his Ability is active is a sight to behold. When the gang members see this young boy casually lift up a car with a smile on his face, they are...quite frightened.
  • Friend to All Living Things: Easily befriends others, whether they be human or animal.
  • First-Name Basis: Since he's only fourteen, everyone in the Agency calls him by his first name.
  • Hair of Gold, Heart of Gold: Has blond hair and is a very optimistic and friendly boy.
  • Moe Stare: One of the reasons why people are so willing to cooperate with him.
  • Nice Guy: Amazingly so.
  • Out of Focus: More often than not he's a background character and, compared to the other Agents, gets into few fights.
  • Overalls and Gingham: Comes from the country and wears a pair of overalls. He even has the straw hat!
  • Perpetual Smiler: Almost always smiling.
  • Pint Sized Power House: Is the shortest and youngest male in the agency and also the strongest.
  • Super Strength: His Ability grants him superhuman strength, but only when he's hungry.
  • Trademark Favorite Food: Not as noteworthy as other characters', but he likes beef bowls. Cows are also his favorite animal. Atsushi points out the irony in this.
  • Unskilled, but Strong: There's no real technique to Kenji's fighting, but his Super Strength makes up for it.
  • Youthful Freckles: Hard to see or not drawn in at times, but they're there.

Junichirou Tanizaki

Voiced by: Toshiyuki Toyonaga (Japanese), Spike Spencer (English)
谷崎潤一郎 - 細雪 note 
Literary references: He is named after Japanese author Junichiro Tanizaki, and his ability is a reference to Tanizaki's novel Light Snow, alternatively titled The Makioka Sisters.
Age: 18
Height: 179 cm
Blood Type: A
Birthday: July 24
Zodiac Sign: Leo
First appearance: Chapter 2/Episode 2

A member of the Armed Detective Agency around Atsushi's age. Often seen in the company of his little sister, Naomi. His ability, "Light Snow," projects realistic illusions within a small area that can move and even inflict pain on others.

  • Adorkable: He is a shy, awkward character.
  • Beware the Nice Ones: One of the nicest members of the Agency, second only to Kenji. Also the most terrifyingly savage when his Relative Button is pushed. Take a look, if you dare...
  • Big Brother Instinct: He gets pissed when Naomi is hurt.
  • Empty Eyes: When his Relative Button is pushed, or he otherwise gets serious, like when he's trying to assassinate the Port Mafia's boss.
  • Fiery Redhead: Averted... Until you hit his Relative Button...
  • Hand-Hiding Sleeves: Sometimes does this with his sweater in the manga.
  • Hidden Depths: In chapter 48, Tanizaki manages to throw off a group of trained killers with his Killing Intent after they threatened to kill his sister, break out of his confines, and almost manages to kill the boss of the Port Mafia.
  • In the Hood: He usually keeps his hoodie tied around his waist, but he'll wear it properly when he needs to get serious or sneak around.
  • Killing Intent: In addition to the incident mentioned above, after Kouyou foils his attempt at killing Mori, Kouyou comments that while she may not be able to see Tanizaki, she is able to feel his bloodlust.
  • Kind Hearted Cat Lover: Cats are listed among his likes, and we already know that he's very kind and shy.
  • Knight Templar Big Brother: He states that things such as morality, ego, and pride do not matter to him compared to Naomi. To keep his little sister safe, Junichirou would let the entire world burn down in flames.
  • Master of Illusion: His power, Light Snow, allows him to project illusions. Said illusions are incredibly lifelike, to the point that Mori (someone who had seen it earlier) could not see that the Fukuzawa he was fighting with in chapter 31 was fake. Tachihara has notable hardship with Junichirou's illusion attacks, as he can also produce duplicates of himself. The trained killer goes around shooting all the illusions, until Hirotsu calls him to stop, because he and Gin also changed positions.
  • Mundane Utility: In WAN, he uses his snow to complete the christmas decorations.
  • Nice Guy: In general, Junichirou is a humble and amiable guy that gets along well with others. He's quick to apologize to Atsushi for the bomb incident in episode 2.
  • Non-Action Guy: Light Snow is a useful ability, but ill-suited for fast-paced combat, and he has no martial arts training. Most of his work in the Agency involves gathering information, scouting locations, and tailing suspects.
    • Subverted in chapter 48. Tanizaki is shown to be able to wield a switchblade effectively, and, coupled with his ability, uses it to escape from a roomful of trained killers. Hirotsu even comments that Tanizaki's Ability is suited for assassinations, as the illusions he makes are not purely illusionary - they can perform powerful melee attacks.
  • Noodle Incident: When Atsushi asks him about his own entrance exam, Junichirou makes a horrified expression before responding that he doesn't (want to) remember.
  • The Nondescript: He stands out the least out of the Agency members. This coupled with his ability makes him good at reconnaissance.
  • Relative Button: Hurt Naomi, and you are dead to him.
  • Screw the Rules, I'm Doing What's Right!: More of, Screw Morals, I'm Saving My Sister.
  • The Sneaky Guy: His Ability is well-suited for this role, so he often is assigned on reconnaissance.
  • Stealth Pun: In Junichirou's own words, his ability transforms the affected area into a screen, which is used to project the illusions onto, and his Ability's color is light green. In other words, a literal green screen. Made a bit more meaningful if you know that his namesake also wrote scripts for movies, and some people say that to understand his career, you'll have to understand his background in movies.

    Kyouka Izumi 

Kyouka Izumi

Voiced by: Sumire Morohoshi (Japanese), Cherami Leigh (English)
泉鏡花 - 夜叉白雪 note 
Literary references: She is named after Japanese author Kyotaro Izumi, who wrote under the pen name Kyoka Izumi, and her ability is a reference to Izumi's play Demon Pond.

Age: 15
Height: 148 cm
Blood Type: B
Birthday: November 4
Zodiac Sign: Scorpio
First appearance: Chapter 7/Episode 4 (cameo), Episode 8 (actual)

An orphan who used to work for the Port Mafia. She was taken in by the Agency and became an official member after being saved by Atsushi. Her ability, "Demon Snow," summons a phantom swordswoman to attack. Unlike the others, her Ability could only be controlled by orders given over a phone, initially by Akutagawa.

  • Action Girl: She can fight on her own even without Demon Snow. After all, she was trained as an assassin by Port Mafia.
  • Animal Motifs: Rabbits. She has a rabbit charm on her phone, has a rabbit stuffed animal she uses as a comfort object, and wears her hair in long pigtails somewhat resembling floppy rabbit ears. It's a reference to the real Kyouka Izumi, who was born in the Year of the Rooster (the opposite sign of the Rabbit), but collected everything related to rabbits as a hobby.
  • Badass Adorable: Don't underestimate her for her cute appearance. Her skills as an assassin are top-notch.
  • Big Eater: Able to eat an astounding amount of boiled tofu, much to the detriment of Atsushi's wallet. She's able to eat a crepe right afterwards, stating that she has a second stomach for that kind of food.
  • Blessed with Suck: Her ability is very powerful, allowing her to rapidly fill her opponents full of holes. However, it only activates when receiving orders over her phone, and she can't control it unless she manages to grab somebody else's phone and use it to call herself. Fukuzawa fixes this problem and allows her to use it normally after she becomes an official member of the Agency.
  • Broken Bird: She acted like an unfeeling killing machine to cope with the unbearable guilt over the deaths her Demon Snow caused, particularly her own parents. When Atsushi first meets her, Kyouka is ready to kill herself to avoid killing people again. Thanks to Atsushi saving her and the Agency taking her in, she starts to get better.
  • Clingy Jealous Girl: She isn't very fond of Lucy, probably because of Lucy's obvious crush on Atsushi.
  • Cry Cute: Her emotionless facade breaks down and she sheds tears as she claims to Atsushi that she doesn't want to kill anymore and attempts suicide.
  • Defrosting Ice Queen: In her first appearance, Kyoukai is borderline emotionless because of what Port Mafia has put her through by using Demon Snow for assassination. After Atsushi rescues her, Kyouka starts to open up because of his kindness.
  • Dull Eyes of Unhappiness: Has these when taking orders from Akutagawa. Loses them after Atsushi rescues her.
  • Emotionless Girl: Subverted. When she's first introduced, Kyouka's personality is similar to that of a doll. She lacks all emotions and appears ruthless when she is ordered to perform a duty. This is soon revealed to be a facade she puts up after being forced to kill by the Port Mafia. After being exposed to Atsushi and the real world, Kyouka reverts back to a normal girl.
  • Exact Words: Kouyou said Demon Snow killed Kyouka's parents. However, she didn't say Demon Snow was in Kyouka's possession at the time.
  • First-Name Basis: She's fourteen, so most of the other characters call her by her first name.
  • Flower in Her Hair: The hair ties securing her pigtails are decorated with flowers.
  • Forced into Evil: Kyouka has killed 35 people since being taken in by the Port Mafia. She really doesn't want to kill people, but couldn't control her powers before Fukuzawa fixed it and had nowhere to run.
  • Gender-Blender Name: She's named after a male author.
  • Girlish Pigtails: She has her hair tied into two low twintails.
  • Girls Love Stuffed Animals: Successfully retrieves a stuffed rabbit from a crane game machine. She's seen hugging it tightly afterwards. Too bad it gets covered in blood after Akutagawa attacks her and Atsushi.
  • Guardian Entity: Double Subverted. Demon Snow only obeys the orders she receives from Kyouka's cellphone. Because of Kyouka's inability to control Demon Snow, she was used by Port Mafia to assassinate people. The first time Demon Snow appeared before Kyouka, she murdered Kyouka's parents. Eventually, Kyouka passes the test to join the Armed Detective Agency and she obtains control over Demon Snow thanks to Fukuzawa's Ability. Kyouka also learns her parents had actually ordered Demon Snow to kill them to protect Kyouka from them because their bodies were infected with a People Puppets ability. Demon Snow was originally Kyouka's mother's Ability and she passed it down to Kyouka to protect her.
  • Hair Intakes: Her hair has a pair of intakes that vaguely look like cat ears.
  • Heel–Face Turn: She used to work for the mafia, but after she is saved by Atsushi, she joins the Agency and eventually gets the courage to betray the mafia and be with the Agency. Downplayed in that she was never evil at heart anyway.
  • Historical In-Joke: The author Kyouka Izumi was a pupil of Kouyou Ozaki. When the latter died, the former took on Ozaki's writing style. Sound familiar?
  • Idiot Hair: She has rather long one, but is by no means a fool.
  • Implied Love Interest: Kyouka is the girl Atsushi has grown the closest to, his roommate and they're very affectionate to each other, but it isn't made explicit whether the two are romantically attracted to each other.
  • Innocent Cohabitation: She starts living in Atsushi's apartment after he saves her and she joins the Agency.
  • Interrupted Suicide: After she admits that she's tired of being forced to kill for the Port Mafia, she jumps out of the train with an armed bomb vest. If Atsushi hadn't ripped the vest off, she would have died.
  • In the Blood: Both of her parents were assassins, and Kouyou trained her to walk in their footsteps.
  • Killing Intent: Inverted. When she tries to kill Kouyou, Kouyou comments that she had been almost unable to sense her killing intent.
  • Kimono Is Traditional: Wears a red kimono, unlike most of the other characters, who wear clothes straight out of the 20's.
  • Little Miss Badass: Killed 35 people prior to joining the Agency. Continues to use her experience with assassination in order to help the Agency.
  • Morality Pet: To Kouyou Ozaki, who cares deeply about Kyouka despite her betraying Port Mafia. Kouyou was the one to secretly give her the file that contained the truth of her parents' death, as well as, in chapter 48, preventing her men from shooting at Tanizaki, for fear that they'd accidentally hit Kyouka.
  • Photographic Memory: She can memorize people's faces and loads of information after taking a look at them just once.
  • Power Incontinence: Can't easily control her ability until Fukuzawa suppresses it to a manageable level.
  • Powers Do the Fighting: Deconstructed. Demon Snow doesn't answer to Kyouka's will and only cuts down people according to the orders she receives from Kyouka's cellphone while Kyouka can only stand and watch. Eventually, Kyouka gains control over Demon Snow thanks to Fukuzawa's Ability and now Demon Snow only attacks the people Kyouka wishes her to. Although, Kyouka complements Demon Snow's fighting abilities with her own in battle.
  • Pragmatic Hero: Kyouka is a genuinely good person and hates the fact her Demon Snow has been used for killing people. That doesn't keep her from using her assassination skills to try and harm those who threaten her, Atsushi and the Agency.
  • Rapunzel Hair: Her twintails go all the way down to her waist.
  • Relatively Flimsy Excuse: Fukuzawa drives away some policemen that were suspecting Kyouka of being part of Port Mafia by claiming she's his granddaughter.
  • Self-Made Orphan: Kouyou reveals that Demon Snow killed her parents. Subverted in Chapter 43, when it's revealed that it was actually suicide and Demon Snow didn't belong to Kyouka until after her parents' deaths.
  • Sixth Ranger: Is the latest addition to the Agency, and is already in full swing.
  • The Stoic: She's usually very calm and unemotional, and has a very...straightforward approach to missions. However, she has plenty of Not So Stoic moments.
  • Sugar-and-Ice Personality: She initially appears cold, emotionless and ruthless. After she starts opening up to Atsushi, Kyouka is revealed to be a curious, playful and very cute girl.
  • Superpowerful Genetics: Demon Snow was originally the Ability of her mother. Shortly before she died, Kyouka's mother learned of a method to pass Abilities down to blood relatives. However, the transference was imperfect, which resulted in Demon Snow only answering to orders from her cellphone.
  • Sympathetic Murder Backstory: Port Mafia took advantage of Kyouka's lack of control over Demon Snow and forced her to work for them as an assassin. By the time she meets Atsushi, Kyouka has already killed 35 people and her guilt over it makes her suicidal. After being saved by Atsushi, Kyouka feels motivated to lead a life where she saves people instead of killing them.
  • Trademark Favorite Food: Tofu, according to her self-introduction. More specifically, boiled tofu. She's also fond of crepes, stating that she has a second stomach for dessert.
  • Tragic Keepsake: Her cellphone was a gift from her mother shortly before the latter was killed by Demon Snow. This is why Kyouka refused to get rid of it despite Port Mafia using Demon Snow through it.
  • Two First Names: Her last name is commonly used as a first name in Japanese.

Tropes that apply in the BEAST universe

In another universe, Kyouka is still part of Port Mafia and has a close relationship with the "White Reaper" Atsushi.
  • In Spite of a Nail: Despite the major differences in the timeline, BEAST!Kyouka still was recruited by Port Mafia, met Atsushi and is working with him, expect as members of Port Mafia instead of the Agency.
  • Love Martyr: Kyouka threw away her only chance to escape Port Mafia and endures working for such a shady organization for the sake of staying by Atsushi's side.
  • Morality Pet: "White Reaper" Atsushi shows his gentler side around Kyouka and he cares so much about her that he agrees to guide Akutagawa to Gin because Akutagawa threatened using Demon Snow to kill Kyouka.
  • Undying Loyalty: Kyouka stays in Port Mafia regardless of her own wishes because she won't ever abandon Atsushi.

Naomi Tanizaki

谷崎ナオミ - ⬛⬛⬛ (痴人の愛)note 
Literary references: She is named after the title character and antagonist of Junichiro Tanizaki's novel A Fool's Love, alternatively titled Naomi, said to be modelled after Tanizaki's actual sister-in-law.

Age: Unknown
Height: Unknown
Blood Type: Unknown
Birthday: March 26
Zodiac Sign: Aries
First appearance: Chapter 2/Episode 2

Junichirou's sister, who works part-time as an office assistant at the Agency. She doesn't have an ability.

  • Beauty Mark: She has one under her left eye.
  • Big Brother Attraction: She has a huge crush on her brother.
  • Double Standard: Rape, Female on Male: Her constant sexual harassment of her non-consenting brother is treated as humorous.
  • First-Name Basis: The other characters call her by her first name, likely to distinguish her from her brother.
  • Foil: To Kirako Haruno. They're both clerks and have no Ability, but there's a great difference in their characters. While Naomi is spoiled, manipulative and willful, Kirako is refined and ladylike. This is because the real Tanizaki wrote them as such too.
  • Hidden Depths: In the manga, she was shown to display a surprising amount of insight and cunningness when she and Haruno evacuated the safehouse, opting to escape with a car from the staff parking instead of the regular parking lot, where Steinbeck and Lovecraft were lying in wait. Haruno comments that were Naomi an ability user, she'd make a capable agent.
    • She notices the correlation between Mii-chan's disappearances and incidents in Yokohama before Souseki's existence is revealed.
  • Little Sister Heroine: Strongly averted. While Junichirou does strongly love his sister, it is only in the normal sibling sense, and he very much dislikes the way she acts towards him.
  • No Sense of Personal Space: Naomi gets too touchy-feely around her brother, to his obvious discomfort.
  • Sailor Fuku: Naomi's school uniform, which she wears while working part-time in the Armed Detective Agency.
  • Shout-Out: She's named after the title character and antagonist of a novel written by the author that her brother is named after.
  • Taking the Bullet: She shields her brother from Higuchi's gunfire, leaving her severely injured.
  • Zettai Ryouiki: Grade C.

  • Badass Normal: Manages to keep her cool even while being pursued by Lovecraft and Steinbeck.
  • Ditzy Secretary: She's calm, collected, and competent on the job and when in danger, but when she's not working she's lazy and obsessed with her cat.

  • Meganekko: Wears a pair of red-framed glasses.
