The Great Stray Dog

The hair is long, straight, silvery (sometimes with a slight bluish tint), and falls to about the middle of the back.
Eyes are silver.
The head—most of the crown—is covered in bandages. According to the plot, this is the result of an operation performed by Fyodor Dostoevsky: Ivan said that during the operation, the part of his brain responsible for unhappiness and suffering was removed.
He wears a white-sleeved shirt with black garters on the sleeves and a black tie under a light brown vest. He also wears black trousers and plain black shoes.

Build and Hair: A short, plump man, mostly bald but with a small tuft of brown hair on top of his head.
Facial features: coarse - large nose, small eyes and a fairly large mouth.
Clothing: Typically wears a dark T-shirt and a jacket (some descriptions call it a gray parka) with a fur hood over it. The hood is often pulled over his head.

His hair is white, layered, and parted to the left. He has a long braid at the back that often falls over his right shoulder.
The eyes are different: one is purple, the other is green. A black slit (scar) runs vertically through the left eye. The right eye appears "empty"—there is no highlight, suggesting possible blindness in that eye. A mask, shaped like a map, or a bandage appears to be worn over the right eye.
His outfit is eccentric, reminiscent of a circus ringmaster or ringmaster. He wears a predominantly black cape (with the right side completely black), black-and-white striped pants, a frilly turtleneck shirt (similar to a loose turtleneck), and dark gloves. A diamond-patterned top hat completes the look.

Build and height: tall and slender young man.
Hair: black, medium length, rather disheveled, reaching to the shoulders.
Eyes: dark purple, narrow and almost always half-closed - because of this, the look often shows fatigue.
Facial features: smooth, with a wide smile.
Clothing: His appearance is rather flamboyant. He wears a white shirt (cut like a caftan, with a high collar and a five-button front; the front is cut in a V-neck, and the trim and "embroidery" are purple), white trousers, and a long black coat with notched lapels and a white fur trim on the collar. He wears knee-high red boots (into which he tucks his trousers), and a white ushanka hat.

others

Main character traits
Reserved and reticent, Gin rarely speaks unless necessary, her silence accompanied by a serious or indifferent expression.
Coldness in her work. As an assassin, she acts quickly and silently, able to sneak up on her opponent and neutralize them before they even notice.
Hot-tempered. Despite her outward calm, Gin is easily angered and can react sharply to provocations—Michizu Tachihara, for example, is often her target.
Dry, sarcastic humor. She knows how to tease others, but she does it succinctly: for example, ironically congratulating someone in a situation where it would come across as particularly poignant.
Caring for her loved ones. Her warm attitude toward her older brother, Ryunosuke Akutagawa, is especially noticeable: she genuinely worries about him and tries to calm him down when he's irritated.
Shyness. Beneath her stoic facade lies a softer side: Gin blushes easily when embarrassed or reminded of her past.
The mafia's loyalty. It strictly follows orders and does not tolerate anyone trying to circumvent the leadership's instructions.

Gin has short dark hair (often depicted slightly disheveled). She typically wears dark clothing—in the anime and manga, she's often seen in her Port Mafia uniform or practical outfits suitable for stealth missions. Another detail: she wears a choker with a cross around her neck.

An important clarification: in the main Bungou Stray Dogs universe, Gin is Ryunosuke's younger sister. However, the character named Rin, who occasionally pops up in discussions, is not her. Rin only appears in the spin-off BEAST, and there she is simply Akutagawa's friend from the slums, not a relative.

Character traits
Capricious and playful, Alice acts like a spoiled child: she might prank Mori, hide to tease him, or exploit his affection for her own ends.
Childlike spontaneity. She loves desserts, drawing, and generally displays typical childish interests.
A Sense of Family. Alice considers the Port Mafia her family and treats its members quite warmly.
A dual nature. In calm moments, it appears sweet and harmless, but when used as a combat ability, it becomes dangerous: it displays superhuman speed, strength, and combat skills, and uses a giant syringe as a weapon.
A complicated relationship with guardians. Despite her affection for Mori, she is sometimes irritated by his overprotectiveness—she behaves like a teenager who longs for independence.

Age: approximately 10-12 years.
Skin: pale.
Eyes: Bright blue (when activated, when abilities are used, they become reptilian-like).
Hair: Long, light-colored (blond), wavy, below the waist. A straight fringe covers the forehead. On the right side of the head is a large red bow.
In her normal appearance, Alice wears a burgundy fitted dress with short, puffy sleeves. The skirt is voluminous and trimmed with white ruffles. The dress features a white buttoned panel and a stand-up collar adorned with a pink bow made of thin ribbon. She wears black and gray striped tights and red patent leather Mary Jane shoes with a wide heel.

When her ability (Vita Sexualis) is activated, Alice's outfit changes: she dons an elaborate pink nurse's uniform with long sleeves and white socks. The skirt is three-layered, ruffled, with a white inset in the middle. The collar is secured with a black bow. On her head is a nurse's cap with a small red bow-shaped pin on the left. Over the uniform is a black corset with crisscross lacing. On her left arm is a bandage with blue stripes along the edges and a thin red one in the middle; a matching bow is at the back. Her tights are white, and her shoes are the same—black patent leather Mary Janes.

mafia boss
Main character traits
Cool and composed. Mori almost never loses control—even in the most tense situations, he remains calm and collected. According to Dazai, he is "the living embodiment of logic."
A strategic mind. He carefully calculates his moves, anticipates potential setbacks, and develops multi-move plans. For him, efficiency, not emotion, is paramount.
Cruelty without unnecessary emotion. Mori is capable of ruthless decisions if they benefit the mafia. However, he doesn't act out of sadism: for him, violence is a tool, not a pleasure.
Manipulative. He skillfully exploits people's weaknesses and desires to achieve his desired result. He often uses his subordinates as pieces in a larger game.
Pragmatism and prudence. He always weighs the benefits and losses, and puts the interests of the Port Mafia above personal feelings and the lives of others.
Respect for the abilities of his subordinates. Despite his strictness, Mori values ​​strong people and allows them a certain amount of freedom: for example, he doesn't punish Akutagawa for his impulsiveness if he's useful.
Alice's Obsession. Mori's only noticeable "weakness" is his attachment to Alice: he spoils her, indulges her whims, and does everything to keep her happy, sometimes at the expense of the comfort of other mafiosi.
A sense of duty to the organization. He believes that the leader simultaneously controls and serves the mafia, and therefore is willing to make difficult decisions and assume responsibility.

Here are some of his traits:

Age and build: Around 40 years old, tall and slim.
Hair. Straight, black, and about chin-length. Usually combed back and pulled back into a ponytail, but two strands frame his face along his cheekbones. When he's playing a doctor, he leaves his hair loose, with those strands falling over his forehead.
Eyes. Purple. Like a mafia boss, they're almost always dark, "sparkless," and their gaze appears tired. He also has a strange pattern on his pupils.
As for clothing, there are two main looks:

As the boss of the Port Mafia, he wears a formal suit: a black pinstriped jacket, black trousers (which he tucks into black boots, military-style), a white purple and white striped shirt, and a purple pinstriped tie. Over this, he wears a black trench coat with a wide, stand-up collar. He also wears a long, dark-burgundy scarf (almost knee-length), which he leaves untied on his shoulders, and white gloves.
In public, dressed as a doctor. The attire is less formal: a purple shirt, a slightly loosely tied dark purple tie, khaki pants, dark brown low-heeled shoes, and a medical gown.

The ability is called "Rashomon." I've compiled the key facts about it—it's truly extraordinary!

The gist is that Akutagawa can transform his clothes (primarily his cloak, but, as it turns out, other items as well) into a special substance. This substance takes the form of a dark, shadow-like beast. And it has a whole host of cool (and dangerous) abilities:

Slice space and physical objects. Rashomon can literally cut through anything.
Transform into sharp blades. The strips of fabric can be used not only for attack but also to block opponents' blows or grab them.
Create protective barriers. Akutagawa can manipulate the space around him to shield himself from attacks. However, activating such a barrier takes time.
Combine with other abilities. A prime example is the synergy with Atsushi Nakajima's "Moonlight Beast." When combined, "Rashomon" wraps around Atsushi's body and tiger claws, enhancing his attack.
Among the specific techniques he used were:

Rashomon: Jaws - A jaw-shaped form to crush the target.
"Demon Armor" is a powerful technique: "Rashomon" wraps itself around Akutagawa's body in the form of black armor. This significantly increases his physical performance, but greatly drains his energy.
Are there any weaknesses?
Yes. Despite its power, the ability has its nuances:

Akutagawa is physically quite weak (he weighs only 50 kg). Therefore, opponents whose abilities can neutralize Rashomon, or those who can quickly attack Akutagawa while he's activating the ability, gain an advantage.
After activating the barrier, it takes time to use the ability again.

Main character traits
Cruelty and ruthlessness. Akutagawa is one of the most dangerous fighters in the Port Mafia: he kills without hesitation and shows no remorse. His worldview is based on the principle of "survival of the fittest": he considers the weak doomed and undeserving of sympathy.
Hot-tempered and intolerant. He reacts sharply to incompetence, easily loses his temper, and can be rude to subordinates. This sometimes leads to mission failure.
Coldness and aloofness. Ryunosuke maintains a distance from others, rarely shows emotion, and almost never smiles. This creates the image of a gloomy and withdrawn person.
Obsessed with Dazai's approval. The key motive behind his actions is the desire to earn Osamu Dazai's approval. It is for this reason that he is willing to carry out the most brutal orders and prove his strength. At the same time, he simultaneously respects Dazai and despises his current lifestyle.
Feelings of Inadequacy. Despite his strength and status, Akutagawa internally feels inadequate—a consequence of his difficult past and constant comparisons to Dazai.
Honesty. He rarely lies, even if the truth sounds cruel.
Caring for his loved ones. Although generally cold, he treats his younger sister, Ryunosuke Gin, with warmth and tries to protect her.

Build and skin: Thin, with very pale skin.
Hair. Short, black. There are longer strands on the sides that frame the face. The color fades to a dirty white toward the ends. The bangs are short, almost completely revealing the forehead.
Eyes: Dark gray, deep-set and narrow. Sometimes appearing a little baggy.
Peculiarity: He often covers his face with his hand—this is due to the fact that he is suffering from a cough.
As for his attire, he usually wears a long black coat (below the knees), under which is a black shirt with a multi-layered ruffled collar and a white jabot. He also wears tapered black trousers and black low-heeled shoes.

port mafia

I have selected the key details of her appearance:

Age and build: teenager, neat features, pale skin, almost alabaster.
Eyes: Blue-grey (sometimes described as dark grey), large, with long, fluffy eyelashes.
Hair: Long, black, with a bluish tint, reaching her hips. Haircut: asymmetrical "hime" (hair combed to the side).
Feature: there is a mole (beauty mark) under the left eye.
As for clothing, Naomi usually wears her school uniform. It consists of a white long-sleeved shirt with a red sailor collar, a black pleated skirt (roughly knee-length), black knee-high socks (mid-calf), and brown loafers. But there are exceptions: for example, after the cannibalism incident, she appeared in a light blue dress with a white top and heels, with her hair pulled back into a high bun.

I've picked out a couple of details to make it easier for you to recognize him:

Build and skin: Slim, of average height (174 cm), with pale, slightly pinkish skin.
Hair. Fiery red (sometimes described as orange), jaggedly cut. Parted in the middle, strands fall down. To keep a few strands out of his face, he pins them with a light gray clip. He wears earrings to match the clip.
Eyes. Large, hazel (brown with a yellow-green tint) color.
Facial features: Slightly upturned nose, standard oval face shape.
As for his attire, he usually wears a black T-shirt with a loose sweater over it (variously described as beige and white or ivory with a V-neck and a black stripe on the collar). He also often ties a red sweater around his waist. Light blue pants and brown shoes complete the look.

Now let's go into more detail.

Hair. Short, black, a little disheveled—it looks like he cut it without a mirror.
Eyes. They are usually closed. In the manga, his eyes are brown, but in the anime adaptation, they were changed to green. The shape of his eyes is quite narrow.
Height and build: 168 cm and 57 kg. Due to his short stature and childish nature, others often perceive him as younger than he actually is.
Clothing. His look truly resembles that of a classic detective (like Sherlock Holmes). He wears a brown hat and a cape (Inverness) over his shoulders. The cape matches the color of his trousers and hat. Under the cape is a dark gray jacket, a white shirt, and a navy blue striped tie. On his feet are long white socks (about three-quarters of the way down his legs) and simple black shoes.
There are also a couple of interesting details:

When Rampo "activates" his ability (though in reality he has no supernatural power—he's simply incredibly observant and intelligent), he puts on a pair of dark glasses. They were a gift from Yukichi Fukuzawa.
His appearance changes slightly across different story arcs: for example, after certain events, he might wear a simple white shirt with a checkered tie and dark trousers, while in other situations, he might wear a sleeveless suit with a black sash. There have also been comical episodes where he dons a teddy bear costume or a jumpsuit with a gas mask for camouflage.

I have selected the main features of her image:

Hair. Short, black, with straight bangs. On the left side of her hair is a gold butterfly-shaped clip.
Eyes. There's a nuance here: in the manga, her eyes are dark gray, but in the anime, they're purple (marengo).
Height and build. Young woman, 166 cm tall, weighs 52 kg. She really cares about her appearance.
As for clothing, Akiko usually wears a fairly recognizable outfit:

a white shirt with puffy sleeves (they end approximately at the middle of the forearm);
black skirt just above the knee;
black gloves, black tie, dark tights;
red high-heeled shoes.

Here are its features:

Hair. Ash blonde with lavender highlights. His hair is asymmetrical: short on one side, longer on the other. There's also a noticeable black streak. Incidentally, this uneven cut isn't just a design detail: the plot explains that he was bullied by other orphans in the orphanage, and he left his hair as is.
Skin. Pale.
Eyes. He has segmented heterochromia: the upper part of the iris is purple, and the lower part (along the lower edge of the pupil) is yellow. Some sources also call these eyes "pi-eyes."
Build: Average height (170 cm), slim.
Regarding clothing:

Before joining the Armed Detective Agency, he wore the shabby clothes provided by the orphanage.
After joining the agency, he was given a new wardrobe: a white shirt (often with the sleeves rolled up to the elbows), a black tie, black trousers, black shoes, fingerless gloves, suspenders, and a belt with a long, loose end. Amusingly, this long end of the belt hangs loose when relaxed, but when Atsushi is excited or frightened, it begins to "live" like a tail.
He also has the ability "Moonlight Beast," which changes his appearance. When partially transformed, his eyes become tiger-like and fangs appear. When more deeply transformed, his limbs transform into those of a tiger and a tail grows. In his full form, he becomes a white tiger with black stripes and golden eyes.

Now let's go into more detail:

Age: 14 years.
Height and weight: 158 cm and 53 kg.
Hair: Short, light, reaching to the back of the head. Bangs are gathered into a knot right in the center of the forehead.
Eyes: golden.
Freckles: present on cheeks.
As for clothing, he usually wears light blue overalls. Underneath, he wears a loose beige shirt, but the sleeves are torn (cut off at the elbows). Underneath, a black tank top is visible, the sleeves ending just below the elbows. Kenji often wears an old straw hat around his neck. He is most often depicted barefoot, but sometimes he wears sandals (variously described as sand-colored or yellowish).

I've compiled a few details to make it easier for you to recognize him:

Height and build: tall (189 cm), thin.
Hair: Light (golden blonde), medium length. Bangs are parted to the right, and the rest of the hair is pulled back into a long ponytail with a few strands sticking out.
Eyes: grass-gray or gray-green shade.
Glasses: He wears them all the time.
Clothing: A beige vest over a black long-sleeved shirt with a red ribbon around the collar (often tied in a bow), beige trousers, and simple brown shoes.
But there are nuances: there are moments in the story where his image changes. For example, after Kunikida was framed and sent to prison, he wears a prison uniform. And when the Armed Detective Agency was accused of terrorism, he donned a white hooded suit and even took riot gear (black boots and gloves that once belonged to the military police).

has the ability "For the Tainted Sorrow", which allows him to manipulate gravity.
What can he do with this ability?
Changing the weight of objects and people: making them incredibly heavy or, conversely, almost weightless - this way he can immobilize an enemy or make him fly up and then abruptly throw him to the ground.
Control your own gravity: reduce your body mass to move at incredible speeds and deliver devastating blows; walk on walls and ceilings, and run along the facades of buildings.
Deflect and return bullets: change their trajectory through gravitational distortion and even send them back at the shooter.
Use surrounding matter as a weapon: pick up pieces of earth, asphalt, rocks and throw them with destructive force, strengthening them with gravity.
The true form of this ability is "Corruption"
This is an uncontrollable, extremely powerful version of his power. In his "Corrupted" state:

control over gravity becomes colossal - Chuuya is capable, for example, of crushing a tank with his bare hands or creating clots of gravitational attraction similar to mini-black holes;
The power grows exponentially, but Chuuya cannot contain it: without external intervention, it will eventually destroy him.

Main character traits
Hot-tempered and temperamental, Chuuya gets easily irritated, especially when his pride is hurt or when Osamu Dazai is nearby—their conflict is one of the main points of the dynamic between the characters.
Proud and straightforward, he doesn't hide his emotions and openly expresses dissatisfaction, and he likes to emphasize his status and strength.
A passionate fighter, Chuuya genuinely enjoys battles; it's important to him to show what he's capable of and to confirm his reputation as one of the Port Mafia's strongest fighters.
Loyal and principled. Betrayal is unthinkable to him, and the well-being of the Port Mafia is his top priority. At the same time, he treats his subordinates with respect and strives to be a fair leader.
He's reasonable when not in a rage. Despite his impulsiveness, in a calm environment, Chuya is capable of thinking strategically, analyzing the situation, and making informed decisions.
A complex inner world. He reflects a lot on his nature and power (especially in relation to the "Corruption" ability and his Arahabaki nature), and questions how "human" he really is, which adds depth to his character.
He values ​​certain things and rituals. For example, he treasures his hat—it's not just an accessory for him, but a symbol associated with important memories.

What are his distinguishing features:

Height and build: Short (160 cm), but muscular, although he may appear thin.
Hair. Bright red (some sources describe it as orange), approximately shoulder-length. Her bangs are slanted, covering more of the right side of her face. Chuya often wears her hair pulled back into a ponytail.
Eyes. In the manga, he has brown eyes, but in the anime adaptation, their color was changed to blue (or gray-blue).
Accessories and clothing. His image is quite recognizable thanks to the following details:
a black hat with a ribbon (sometimes with a thin silver chain hanging from the brim);
black choker (ribbon collar) on the neck;
almost always black gloves (he takes them off only when activating his ability);
His outfit varies across arcs and adaptations, but he often wears a white shirt, vest, cropped jacket, black trousers, and boots. He also often drapes a long black coat over his shoulders, like a cape. He's a port mafia.

What can this ability do?
Nullifies the abilities of other espers - upon direct physical contact, Dazai disables the opponent's superpowers.
It works even through a partial connection with the skin - for example, if the enemy touches the tied up Dazai, the ability still works.
It works constantly - he doesn’t need to activate it specially.
Important limitations
Only upon contact - the ability does not work at a distance.
It doesn't block non-abilities - for example, it doesn't affect Ranpo Edogawa's "Super Deduction" because it's not an esper power.
It also interferes with beneficial effects, preventing Dazai from receiving help from healing abilities (like Akiko Yosano's "Don't Give Up Your Life").

Main character traits
Ironic and dramatic, Dazai constantly jokes, often in a dark vein, and is prone to exaggeration, turning almost any situation into a tragicomedy. For example, he regularly staged comical suicide attempts.
Smart and calculating. Behind his outward laziness and carelessness lies a keen mind: he develops complex, multi-step plans, calculates the actions of his enemies, and skillfully manipulates people. In the past, he was one of the key tacticians of the Port Mafia, and later became a valuable detective.
Charismatic. He has a special appeal—he easily gains attention and trust, and knows how to persuade and motivate others to take the actions he desires.
Cynical, but not without empathy. Dazai often acts harshly, speaks bluntly and without embellishment, and can use people as pawns in his game. At the same time, he genuinely cares for those close to him (especially Atsushi) and tries to guide those in whom he sees potential.
Obsessed with death, his constant talk of suicide isn't just a joke: it's a crucial part of his inner conflict. He seems to be searching for meaning by experiencing extremes and confronting the dark side of human nature.
Contradictory. He combines cruelty and caring, laziness and incredible efficiency, cynicism and the ability to truly connect with people.

Age and build: Young man, approximately 22 years old. Tall and slender.
Hair. Short, slightly wavy, dark brown. Bangs frame the face, with some strands gathered in the center of the forehead.
Eyes. Narrow, dark brown.
Skin. Light.
Clothing. He usually wears a long, sand-colored trench coat, the belt left untied. Underneath, he wears a black vest over a light blue striped shirt. He also wears a bolo tie (tie clip) with a brown ribbon and a turquoise pendant, beige trousers, and dark brown shoes.
Bandages. This is one of the most noticeable details: bandages are wrapped around the entire body, revealing only the face, arms, and legs. Beneath the bandages are numerous scars from previous suicide attempts.
What was it like before? When Dazai was a member of the Port Mafia, his appearance was different: he wore a long black trench coat (length below the knees), an eyepatch over his right eye, and a sling over his right arm—also a result of past injuries. In other situations (such as the Yokohama Fog incident or the Agency celebration), he appeared in different outfits: a white vest over a black suit with a brown tie and white trousers, and after his arrest, a white prison uniform.
