Ogai Mori
Appearance
Mori is a tall, slender man in his 40s. He has straight, chin-length black hair, combed back and tied in a ponytail, with two strands framing his face. His violet eyes are almost always completely dark, lacking a sparkle, and appear tired. In public, he often wears more modest clothing, reminiscent of a doctor's uniform. Personality and role in the plot
Mori initially appears as an awkward and anxious middle-aged man, but his true nature is later revealed: he is a cool-headed strategist who maintains composure in any situation and is able to calculate his moves many steps ahead.
As a mafia boss, Mori is cruel and ruthless. He's willing to manipulate people, inflict psychological trauma, and sacrifice allies for the organization's benefit. His cruelty is not without logic: he always weighs the benefits and losses, choosing the best decisions for the Port Mafia as a whole. Mori disregards the emotions of others, viewing them merely as tools to achieve his goals. His actions have deeply traumatized characters like Akiko Yosano and Osamu Dazai.
His ability is called "Vita Sexualis." It allows Mori to materialize Eliza, a young girl who is completely subservient to his will. Mori can shape her personality, forcing her to perform any task, from protecting her master to participating in his plans. However, summoning Eliza drains Mori of energy, so he cannot do so when ill or weakened. History and Connections
The character was based on the real-life Japanese writer and military doctor Mori Ogai (real name: Rintaro Mori). Before leading the mafia, Mori was a military doctor and then became an underground doctor within the organization. He assassinated the previous mafia boss to seize power, and made Dazai a witness to the event. Mori was the former partner of Yukichi Fukuzawa, the president of the Armed Detective Agency. He loves children.

Chuya Nakahara
Appearance
Chuuya is a young man of short stature but with a muscular build. He has bright red hair, which he wears in a ponytail combed to the left side, and large eyes—brown in the manga and gray-blue in the anime adaptation. He often wears a black hat with a ribbon and a silver chain, and his attire includes a white shirt under a vest, a bolo tie, a cropped jacket, and a long black coat.
Character
At first glance, Chuya appears to be a temperamental, arrogant, and rude person. He loves fighting, happily demonstrates his combat skills, and is very proud of his reputation as the strongest martial artist in the mafia. In combat, he doesn't hesitate to taunt his opponents. However, behind this outward bravado lies a more complex character. He is capable of compromise and rational decisions when necessary. Chuya is not inclined to thoughtlessly sacrifice people's lives, although he is willing to eliminate the mafia's enemies by any means necessary. Ability
His ability is called "For Corrupted Sadness" (Yogorecchimatta Kanashimi ni). It allows Chuuya to manipulate gravity: he can alter the gravitational pull of objects he comes into contact with, create and manipulate gravitons. With it, he can walk on walls, "deflect" incoming bullets, and even create craters beneath his feet.
The ability has a true form—"Corruption." When activated, Chuuya loses control: his physical capabilities increase dramatically (he can, for example, smash through a tank with his bare hands), and miniature black holes form around him, consuming everything around him. However, without Dazai's help to neutralize his ability, Chuuya will be unable to stop and will ultimately perish. His ability, "Arahabaki," is named after an ancient Japanese deity associated with destructive force. Chuuya was formerly a member of the Sheep group, but was betrayed by its members.
His relationship with Dazai is complex and contradictory: they constantly tease each other, but in critical situations they trust each other.

Ryunosuke Akutagawa

Under the coat, he wears a white shirt with layers of pleated fabric and a white frill. On days off, he might wear a simple black coat and tinted rimless glasses. Personality and views
Akutagawa holds a rigid, social Darwinist worldview: he believes the weak must die and make way for the stronger. He is unafraid of pain and defeat if it will help him earn the approval of "a certain person." His ruthless and vicious nature makes him one of the most dangerous members of the Port Mafia. He is willing to commit cruel acts for the sake of the organization and his own interests. However, he dislikes senseless torture and prefers to kill outright whenever possible. He maintains an aloof demeanor with both subordinates and superiors, but his composure is fragile—he easily loses his temper. Ability
His ability is called "Rashomon." It allows him to transform his clothes (and any other clothes) into a black beast that can devour everything, including space. Furthermore, strips of Rashomon cloth can transform into sharp blades for blocking blows and capturing prey. History
Before joining the Port Mafia, Akutagawa was an orphan living in the slums. He was recruited by the Mafia due to his ability and became Dazai's apprentice, who trained him quite harshly.
After Dazai left the Mafia, Akutagawa began targeting the surviving Mafia soldiers to force Dazai to acknowledge him.

His own ability mutated his cells, turning him into a vampire, earning him the nickname "Dracula." Eight years ago, he was named one of the "ten worst plagues of humanity." Afterward, he swore an oath never to turn others into his kind again and was reluctant to join Fukuchi's plan to wreak havoc. However, when Fukuchi threatened him, Bram ultimately complied, breaking his oath.
His ability is called "Immortal King." It's an infectious one: anyone Bram bites turns into a vampire. The "victim" also gains the ability to create new vampires. The rate of infection is extremely high. Furthermore, the ability seems to allow the dead to be brought back to life. Bram himself has complete control over the vampires created in this way. World governments consider this ability one of the "ten major disasters capable of destroying the world."

childhood was difficult: he lived in an orphanage, where he was humiliated and abused by the principal. Because of this, he grew up with low self-esteem, hated himself, and was fixated on the past. He often made bad decisions, relying on other people's opinions.
However, at critical moments, his will grew stronger, and he was ready to risk himself for the sake of others. Atsushi had a strong sense of morality and sought to protect the weak. Ability

He enjoys teasing his colleagues, such as Doppo Kunikida.
Ability
"Incomplete Human" (人間失格, Ningen Shikkaku) is an ability that allows Dazai to neutralize another esper's abilities through direct physical contact.

Howard Phillips Lovecraft is one of the most enigmatic members of the Guild.
Character
Lovecraft is an extremely apathetic and detached character. He cares little: he can fall asleep in the middle of a fight, reacts indifferently to chaos and destruction, and is lazy about his work. He often delegates tasks to his partner, John Steinbeck, and simply wants to "go to sleep." He's not so much evil as detached from human emotion—as if he exists on a different wavelength. Appearance and details
Height: about 190 cm.
He looks imposing yet relaxed, a look that emphasizes his "non-human" nature. Ability
His power is called "The Great Old Ones." It allows Lovecraft to transform part or all of his body into a monstrous form, complete with tentacles and the features of Lovecraftian creatures. In this state, he becomes nearly invulnerable: damage is only dealt to attacks from within.

An important detail: the plot emphasizes that the "Great Old Ones" are technically not even a typical esper ability—which is why it can't be neutralized by Dazai (whose power nullifies other people's abilities). Lovecraft also boasts incredible regeneration: he can recover even from severe injuries.

John Steinbeck is one of the members of the Guild of Espers.
Appearance
John is a young man of average height and build, with short blond hair and blue eyes. He is most often seen wearing a white shirt with the sleeves rolled up to his elbows, blue gardening overalls with a single strap, and a hat with a small visor. In some chapters of the manga, he can be seen wearing a short hooded jacket, pants, and boots. Personality and Motivation
At first glance, John appears to be a relaxed and friendly man, occasionally commenting on rural matters and conversing with his partner, Lovecraft. However, behind this polite facade lies a cunning and cruel nature.
His main driving force is caring for his large family. To provide for them, he joined the Guild, where the pay was good. At the same time, John sincerely hates Fitzgerald for controlling people with money. Steinbeck realizes that he himself used money to help his family, but this doesn't change his disdain for the Guild boss's methods. Ability
His ability is called "Grapes of Wrath" (Japanese: 怒りの葡萄, Ikari no Budo). It allows John to grow vines from any part of his body. With these vines, he can:
to seize and hold enemies with great force, causing them pain;
intertwine vines with other plants, accelerating their growth to pursue enemies at a great distance;
Use vines as a shield. Furthermore, through his connection with plants, John can sense their vibrations, making him extremely difficult to attack stealthily. This ability can also interact with others: for example, Steinbeck spread Q's curse ability through plants.
