Main ; : :A 25-year-old normal programmer and office worker who suddenly finds herself living with a
dragon named Tohru after removing a divine sword from her on a drunken night. While typically stoic and kind-hearted, she can get wild when drunk. She will usually get hangovers resulting in the cast having to wait on her hand and foot. She has a particular fascination with maids. She is occasionally mistaken as a boy due to her lack of feminine features—particularly her flat chest—and apparent lack of sexuality. ; : :A female dragon of the Chaos faction who comes from another world called the dragon realm and is capable of using magic to perform such tasks as "perception-blocking" (which causes people to simply overlook her), repairing damage she may have caused, or transforming between a dragon and a human. After her life is saved by Kobayashi, she falls in love with her and starts living in her flat as a maid. She usually retains her horns when changing into human shape, and occasionally retains her tail and wings. She is commonly mistaken for a
cosplayer due to her appearance. A
running gag involves her attempting to feed Kobayashi pieces of her tail (which she can regenerate) with her cooking as a sign of affection and a sign of love. Initially, Kobayashi doesn't reciprocate Tohru's feelings and only sees her as nothing more than her personal maid. However, in chapter 97 of the manga, she finally confesses her feelings to Kobayashi and they become a couple. ; : :Tohru's friend from the dragon realm who was exiled from her world for pulling one too many pranks on other dragons and wound up living with Kobayashi as well; she initially assumes that Kobayashi seduced Tohru into staying and wanted the latter to return to their original world, but then grows increasingly attached to Kobayashi as the series progresses, viewing her as a mother figure. Though Kanna has yet to align with a dragon faction, Kanna is highly regarded due to bearing the name "
Kamui"; her basis and attire are inspired by
the culture of the indigenous natives of Hokkaido, and she herself claims to be from
Ushishir. Although she is much older than she appears, she is very young by dragon standards, equivalent to a primary school student at , which she attends as a third grade student bearing Kobayashi's surname. She bears feather-like horns and a thin tail ending in a bulb, and is capable of recharging her depleted magical energy with electricity. She is the crush of Riko Saikawa, which she reciprocates whereupon the two state they want to marry each other.
Dragons ; : :A
water dragon belonging to the Order faction, rival to Tohru's Chaos faction, who ends up working alongside Kobayashi at her office after getting stuck in the human world. She is as powerful as she is diligent and driven, but also naive, indecisive, and with a ravenous appetite; she will often go broke (in part due to her low income) and is easily swayed by food, primarily if it is sweet. Her human form is distinguished by purple hair, a horn (which she hides for work), her habit of having a jacket or kimono hanging off her shoulder, and wielding a trident; is the identity she uses while in Kobayashi's workplace. Several chapters of the manga focus on her having had an old friendship with Tohru which was broken due to their alignments, with chapter 96 revealing that she has feelings for Tohru that she confesses to Tohru, despite being expectedly spurned. ; : :A female adaptation of
her namesake, —often referred to as Lucoa (from "Quetza
lcoatl" as adapted to the
Japanese syllabary)—is another friend of Tohru who is aligned with neither faction, having lost her divine status centuries ago after getting drunk and causing a scandal involving her younger sister; Tohru will sometimes casually reference this much to Lucoa's embarrassment. Lucoa appears in her human form as a tall, well-endowed woman with striking
heterochromia. Tohru sees her as a source of wisdom, but Lucoa's discomfort with clothes—which she tolerates should she be required to be dressed—often leaves her preferring to wear tight-fitting clothing that shows a lot of skin; a running gag involves others criticizing her for this, marking her as a pervert, or—should they be a staff member of a public place—dragging her away should her attire be inappropriate. Most notably, she lives with Shouta after she interrupted his demon-summoning spell to prevent him from summoning a dangerous demon, causing him to mistakenly believe she is a
succubus; and in her attempts to warm him up to her, she often becomes overly affectionate with Shouta, scaring him. ; : :Another adaptation of
his namesake and old friend of Tohru. He is a male Chaos faction dragon with a cold demeanour, disdainful mentality, and strong distrust for humans. He appears as a refined young man with long black hair and red eyes in his human form. After he decides to stay on earth, Tohru attempts to find him a place to do so (under the name ); Fafnir eventually comes to live with Takiya, becoming obsessed with video games and
popular culture. ; : :A Chaos faction dragon who targets Tohru because of her relationship with a human, attempting to destroy the city in the process. She then turns her eye to Kobayashi, trying to drive her and Tohru apart to prove her beliefs; but after Kobayashi and Tohru save her from an Order dragon, she has a change of heart and ends up living with them. Ilulu appears in her human form as a petite girl with a very ample bust. Her mental growth was somewhat impaired due to various beliefs that were forced on her by other chaos dragons. When she was younger, she enjoyed playing with human children; and since coming to Earth, she has taken up a job at a candy store, so that she can still see children when they are happy. ; : :Tohru's father, also called as by other dragons. He disapproves of Tohru's relationship with Kobayashi due to their beliefs as Chaos dragons and because of a non-interference rule about Earth. He attempts to force Tohru to leave with him but decides to let her stay after Kobayashi stands up to him, despite knowing how easily he could kill her. He still leaves Kobayashi alive, as he does not want to risk angering Tohru, who he recognizes as stronger than him.
Humans ; : :Kobayashi's co-worker who is initially believed by Tohru to be a rival for Kobayashi's affections, but is really just an
otaku who thinks of Kobayashi as "one of the guys" and likes to talk about maids with her. Kobayashi helps him set up during
Comiket every year. Fafnir eventually decides to live with him in the human world due to his enormous game and manga collection. ; : :Kanna's primary school classmate who can be haughty towards her other classmates. Should someone strike her as cute, she will be overwhelmed with affection towards that person; she is thus initially hostile towards Kanna but soon develops a crush on her, with a running gag involving her being flushed with bliss for most of her time around Kanna. Kanna reciprocates her feelings, and the two state they want to marry each other. ; / : :Riko's older sister who pretends to be a housemaid as her hobby and thus gets on very well with Kobayashi. She so deeply identifies as "Georgie" that she seems to have forgotten her real name, which was later revealed as "Sanae". ; : :A young mage who Lucoa starts living with after she interrupted his demon-summoning spell. He is thus convinced that Lucoa is a succubus, and though she tries to clear the misunderstanding, her overly familiar antics do little to help her case. A running gag involves him blushing and running away every time he gets caught up in such antics and scolding her as a "demon". In the anime, he is in fifth grade at the school Riko and Kanna attend. His father is the director of Kobayashi's company, who designed their
programming language based on magic from the other world, and keeps tabs on Tohru and Kobayashi for the Emperor of Demise. ; : :Taketo is a highschooler and grandson of the owner of the candy shop where Ilulu works. Embarrassed at first with her lack of common sense and voluptuous body, Taketo eventually grows close with Ilulu, who starts having romantic feelings for him. ==Media==
