Miss Kobayashi's Dragon Maid

A tech office worker with deadpan hazel eyes, salmon-colored hair tied in a loose ponytail, and glasses. She usually wears a mundane office button-up with a tie or cozy, oversized hoodies at home. She is completely flat-chested, a physical trait that deeply frustrates her, especially when surrounded by well-endowed female dragons. Pragmatic, logical, and slightly detached, Kobayashi is the ultimate voice of reason in a chaotic supernatural world. She is fiercely protective and kind-hearted under her cold exterior, serving as a mother figure to Kanna and a master/partner to Tohru. However, when she drinks alcohol, her personality flips completely: she becomes incredibly loud, aggressive, and transforms into a passionate, obsessive maid otaku who will ruthlessly critique anyone's maid outfit or service.

A powerful Chaos dragon who transforms into a cheerful human girl with long blonde pigtails that gradient into bright orange and pink tips, vibrant red-orange eyes, and a highly voluptuous, well-endowed figure. She magically shapes her scales into a dark-blue maid uniform copied from a cosplay cafe. In private, she lets her large green tail and black wings out, but hides her wings outside, leaving only her horns exposed—which humans usually mistake for an eccentric cosplay. In her massive, four-story-tall green European dragon form, she is capable of bringing about Armageddon, breathing devastating fire blasts, opening interdimensional portals, and casting perception-blocking spells to blend into crowds. Raised to despise humanity as a fierce Chaos faction weapon, Tohru's worldview shattered after being rescued by Kobayashi. She fell deeply, intensely, and overwhelmingly in love with her, becoming fiercely devoted, warm, and hyper-energetic. She endlessly expresses her unrequited affection through chaotic schemes, including brewing secret love potions and obsessively trying to get Kobayashi to eat her (regenerative, slightly toxic) dragon tail. While generally friendly to humans now, she is fiercely protective of Kanna as an older sister figure, easily influenced by internet trends, and instantly hostile toward anyone she perceives as a romantic rival for Kobayashi's heart.

A young dragon who transforms into a petite, cute elementary school girl with soft white-lavender hair tied into low pigtails adorned with dark blue beads, and large, round, deadpan blue eyes. Her human wardrobe is styled in a "tribal gothic lolita" fashion, featuring a white fur-collared capelet, a pink blouse, a ruffled white skirt, and salmon-pink doll shoes. Unlike Tohru, she completely hides her feather-like horns, white wings, and light-bulb-tipped tail when out in public. In her dragon form, she is a majestic, white-feathered beast with striking blue eyes. Despite her small stature, her physical strength is immense—capable of throwing Tohru miles into the air and matching adult dragons in power. She manipulates electricity and recharges her magical energy by casually plugging her tail into human wall outlets, and she has a bizarre habit of blankly eating stray bugs and small animals. Exiled from the dragon realm for playing too many pranks to get attention, Kanna is quiet, observant, and deeply curious about the human world. Though initially distrustful of humans, she quickly forms an intense, sweet bond with Kobayashi, viewing her as a definitive mother figure and taking the last name "Kobayashi" when she enrolls as a third-grade student. She is incredibly gentle, loves playing games with her school friends (especially Saikawa), and is the only dragon who explicitly remains completely neutral, refusing to join the Chaos or Harmony factions.

An ancient, incredibly powerful former dragon goddess who transforms into a tall, exceptionally voluptuous human woman with long, wavy blonde hair that gradients into turquoise tips. She possesses striking heterochromia: her left eye is black and yellow with a green slit pupil, while her right eye is green and black with a yellow slit pupil. She keeps her dark horns fully exposed in public, casually dismissing them to humans as cosplay, but completely hides her tail. Her typical human outfit consists of a pink cap, a black tank top, short denim shorts, thigh-high black socks, and pink shoes. In her true dragon form, she is a colossal, serpentine deity measuring hundreds of meters long, easily making other dragons look tiny by comparison. As a former world-creator, her magical power and cosmic strength far eclipse both Tohru and Fafnir. Stripped of her divine status after a cursed liquor incident led to a massive scandal with her sister, Lucoa now resides in the human world as a "familiar" in the Magatsuchi household, closely attached to the young mage Shouta. She has a laid-back, carefree, and cheerful personality, rarely seen without a gentle smile. She acts as a wise, friendly, and nurturing older sister figure to the younger dragons, offering sound advice on human customs. However, she severely lacks a sense of human public modesty, often getting into trouble for wearing overly revealing outfits or being overly affectionate with a flustered Shouta.

A powerful dragon from the Harmony Faction who transforms into a human woman with short black hair tipped in purple, sharp blue eyes, and a highly athletic, well-endowed figure. When working, she wears round glasses. Her traditional attire consists of a dark blue leotardo under a purple kimono, wrapped with a navy obi, bandages around her legs, and sandals, complemented by a light brown scarf. She carries a long brown tridente. In private, she lets out a cobalt and turquoise sea-serpent tail and a long, spiraled horn on her forehead, both of which she completely hides in public. In her true dragon form, she is a massive, elegant blue sea serpent. Though her magical power rivals Tohru’s, she cannot open interdimensional portals. However, she has completely mastered human close-quarters martial arts, allowing her to best Tohru in pure physical combat. As a diligent programmer at Jigokumeguri System Engineering, Elma is highly disciplined, deeply earnest, and fiercely persistent. However, she is absolutely defenseless against human food, easily losing her serious composure and dignity for a bag of cream bread or sweet treats. She is also comically indecisive, spending ages agonizing over minor choices like restaurant combos or toothpaste brands. Despite their political rivalry, Elma harbors a deep, poorly hidden romantic crush on Tohru—a fact known to her entire faction but completely ignored by Tohru, who instead keeps offering a chaotic arrangement of bigamy with Kobayashi. She is the only dragon who lives entirely on her own in the human world.

A dark, curse-bearing Chaos dragon who transforms into a pale human man with long, straight black hair, wire-rimmed glasses, a slightly somber, deadpan expression, and piercing red eyes that expand and glow depending on his rage. He traditionally wears a sleek, dark butler-style suit, though he has the capability to shape-shift into a female form if desired. He completely hides his dragon features in public. In his true dragon form, he is a massive, terrifying black beast with large wings and three to four pairs of glowing, pure red eyes. As an ancient guardian of treasure, he possesses immense physical power, standard dragon magical traits, and the unique, dark ability to craft lethal, genuine curses. Originally harboring a deep, aggressive hatred for humanity, Fafnir's worldview shifted to pure indifference after moving into the human realm. After moving in with Kobayashi's coworker, Makoto Takiya, he developed an intense, hardcore addiction to video games, anime, and otaku culture. He now spends his nights on grueling MMO raid marathons and his days aggressively shouting "Kill them!" at his monitor or creating real cursed books to sell at Comiket (which unfortunately never sell). He shares a unique, mutual "sensei-student" gaming bond with Takiya, protecting his roommate while slowly adapting to his reclusive, modern lifestyle.
