The World of BSD (Port Mafia)
• Ougai Mori is the calculating and ruthless boss of the Port Mafia, a former military doctor who runs the organization with pure logic. His ability, "Vita Sexualis," materializes a girl named Alice, who obeys his will and whims.
• Chuuya Nakahara – The hot-tempered but loyal head of the mafia executive committee, and Osamu Dazai's former partner in the Double Black duo. His ability, Vague Sadness, allows him to manipulate the gravity of any object or person he touches. • Ryunosuke Akutagawa – The cruel and driven commander of the Black Lizards, who craves the recognition of his former mentor, Dazai. His ability, Rashomon, transforms his cloak into a dark, carnivorous monster capable of tearing apart space and enemies.
• Kouyou Ozaki – A sophisticated mafia enforcer who wears a traditional kimono and acts as a guardian to young espers like Kyouka Izumi. Her "Golden Demon" ability summons a sword-wielding phantom warrior to fight at her command.• Motojiro Kaji – An eccentric and insane mafia bomber whose "Lemon Bomb" ability makes him completely immune to the explosions of his own lemon-shaped projectiles.
• Q (Yumeno Kyusaku) - A child esper locked away because he is dangerous, with the ability "Dogra Magra", which sends terrible curses and hallucinations to anyone who causes him physical pain.• Ichiyo Higuchi - Akutagawa's loyal assistant, ready to take any risk for him, despite not having her own esper ability.

• Ryuro Hirotsu is the elderly and charismatic commander of the Black Lizards with the ability "Falling Camellia", which generates powerful kinetic force upon contact.
BSD World (vda)
• Atsushi Nakajima is the story's protagonist, a hesitant but extremely kind orphan who finds a home and meaning in life at the Agency. His "Moonlit Beast" ability allows him to partially or fully transform into a powerful white tiger with high regeneration.
• Osamu Dazai is an eccentric, enigmatic, and brilliant detective with suicidal tendencies and a dark past in the Port Mafia. His ability, "Incomplete Human" (or "Confessions of an Incomplete Human"), allows him to completely neutralize the powers of others with a single touch.
• Doppo Kunikida is Dazai's strict, idealistic partner who obsessively plans every second of his life in a notebook. His ability, "Doppo's Poetry," allows him to materialize any object no larger than a page in his notebook if he writes its name.
• Ranpo Edogawa is the world's greatest detective, a childish sweet-toothed man who can't even use the subway, but can solve any crime in seconds. His "ability" of "Super Deduction" isn't actually a magical power—Ranpo is simply a natural genius, despite believing otherwise.
• Yukichi Fukuzawa is the Agency's stern and just director, a master swordsman, and a former government assassin. His "All Men Are Equal" ability only affects his subordinates, allowing them to perfectly control and suppress their own dangerous powers (it was thanks to him that Atsushi tamed the tiger).
• Akiko Yosano is the Agency's staff doctor, a strong character with feminist views and terrifying treatment methods. Her ability, "Don't Give Up Your Life, My Love," can instantly heal any fatal wound, but only works when the patient is literally dying (which forces her to "finish off" her wounded colleagues).
• Junichiro Tanizaki is a friendly young man who acts as an engineer and field agent, but becomes incredibly violent if his sister Naomi is threatened. His ability, "Light Snow," creates illusions, disguising the surroundings or people within a certain radius.
• Kenji Miyazawa is an incredibly optimistic, honest, and strong boy who came from a remote village. His ability, "Not Yielding to the Rain," grants him immense physical strength and invulnerability, but it only activates when Kenji is hungry (he immediately falls asleep after eating).
• Kyouka Izumi is a former Port Mafia assassin who was rescued by Atsushi and later joined the ADA. Her "Snow Demon" ability materializes a ghostly phantom with a sword, which initially obeyed only orders from a phone receiver, but later came under her personal control.
