  Quetzalcoatl (ケツァルコアトル Ketsarukoatoru), often refered to as Lucoa (ルコア Rukoa), is a supporting character of Kobayashi-san Chi no Maid Dragon and a main protagonist of Kobayashi-san-chi no Maid Dragon: Lucoa wa Boku no xx Desu. She is a former dragon goddess and an old friend of Tohru. Quetzalcoatl was exiled from her seat of goddess after consuming some cursed liquor, that led her to enter into a scandalous affair.


Quetzalcoatl Dragon form Manga

Lucoa's true form

In her human form, Quetzalcoatl is a tall, fair-skinned and voluptuous woman with enormous bouncy breasts, ample thighs, and plentiful hips. She has long, wavy blonde hair, taking on turquoise and green color at the ends. She has heterochromia, where one iris has a different coloration from the other. Her left eye is black on the outside and yellow on the inside, with a green, slit pupil. Her right eye is green on the outside with designs and black on the inside with a yellow, slit pupil. Although she tends to keep her eyes closed most of the time.

Like Tohru, Quetzalcoatl keeps her horns but does not retain her tail, or decides to keep it hidden. When she first arrives at Kobayashi's home, she dons a pink cap, a choker and necklace (only in the manga), a black tank top that exposes her cleavage and stomach (covers her stomach in the anime), jean booty-shorts that reveal a generous portion of her buttocks (in anime), thigh high black stockings, and pink shoes. She does not wear a bra, which allows her voluminous breasts to jiggle and bounce without much restraint with every movement she makes, creating a distracting environment to those around her, especially males. However, this seemed to be advantageous as it helped a young boy named Shouta Magatsuchi win a relay race as many of the other male runners were distracted by her breasts bouncing. Kobayashi even comments that her outfit "does not leave much to the imagination."

In her dragon form, she takes the appearance of a large 'amphithere' dragon with broad feathered wings and a mask-like skull. At one point she refers to herself as a 'Feathered Serpent.' She is by far one of the largest dragons.


Lucoa appears to be laid-back and carefree who is rarely seen without a smile. She is wise, kind and nurturing who often has advice for her younger kin.[1]

As a former goddess, she is better tuned to human customs, as seen when she explains to Tohru why Kobayashi was not receptive to Tohru's initial cleaning regimen. Despite this, however, Lucoa seems to lack some sense of dignity severely. She is not above using her body as a means of getting what she wants, shown when she attempts to use her alluring figure as an offering to the young boy Shouta into allowing her to stay in his home.

Lucoa appears to have a flirtatious nature, shown when she is disappointed when Shouta refuses to lotion her body at the beach, regularly takes baths with him and thrusts her colossal breasts in his face, much to the boy's discomfort. She has no issue with showing off her sensual body, opting to wear a skimpy bikini that barely covered her flesh at all to the beach, and caused her to be detained and forced by a lifeguard to wear something less revealing. A similar incident occurred when she showed up at an anime convention boasting a skimpy string bikini. Lucoa commonly wears skin tight or revealing clothing, showing off her arousing body. Her sexual nature often has her being compared to a succubus or demon by Shouta and her other dragon companions, such as Tohru.

Due to an event when she was a former goddess when she became drunk after consuming a bottle of cursed liquor, she was involved in a scandalous affair and stripped of her godhood. When Tohru mentions said scandalous affair, she is always cut off by a surprisingly flustered Lucoa who is usually very calm and laid-back.


Lucoa is a former goddess, who is later stripped of her godhood after consuming a cursed liquor that a friend had given her, which led to a scandalous affair with her sister. However, she claims to be responsible for the development of civilization despite no longer bearing any title as a deity.

She currently resides in the Magatsuchi household as Shouta's familiar.



Shouta Magatsuchi

Quetzalcoatl lives with Shouta but does not work for her stay. The two of them have a complicated relationship as Shouta sees Quetzalcoatl as a succubus or demon rather than a dragon. Quetzalcoatl will often try to get Shouta's attention, but due to her massive breasts she often ending up flustering and embarrassing him instead.


Tohru is Quetzalcoatl's old friend. Quetzalcoatl has faith in Tohru as she asks her and Kobayashi for help in convincing Shouta that she isn't a demon. She also cares for Tohru and will occasionally visit Kobayashi's place to check up on her.


Quetzalcoatl and Kobayashi have a good relationship. They'll often talk to each other while Tohru is away and Kobayashi trusts Quetzalcoatl enough to tell her how she truly feels about Tohru.


  • Lucoa tends to be the main fan-service character, possessing the largest breasts in the series.
  • Lucoa is based on the Aztec god Quetzalcoatl.
  • The story that Tohru tells of her sleeping with her sister is taken straight from Aztec mythology (although some versions say that it was simply a priestess).
  • She is by far the most powerful dragon in the series so far since she is a former ex-goddess and her powers are far beyond Tohru and Fafnir in terms of strength and powers.
  • She is one of the characters throughout the series who don't open their eyes often, but she is the only character often has shut eyes, it is just to hide her human or dragon eye.
