Quetzalcoatl

Quetzalcoatl 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. 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, as shown when she attempts to use her alluring figure as an offering to Shouta, hoping to allow her to stay in his home.

Quetzalcoatl lives with Shouta but does not work for her stay. The two 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 ends up flustering and embarrassing him instead.
