I wouldn't have planned on covering this one if not for the fact that it too will be getting an anime adaptation this winter, and by Kyoto Animation no less. It seemed an odd choice of a property for them, so I wanted to find out myself if this was another Nichijou in the making or just another Phantom World?
As with most things, the truth is a bit more complicated.
MISS KOBAYASHI'S DRAGON MAID (Kobayashi-san Chi no Meidoragon), by coolkyoushinja. First published in 2013 and first published in North America in 2016.
PLOT:
Kobayashi wasn't looking for a roommate. She just happened to drunkenly wander her way up a mountain and bond with an equally distressed dragon named Tohru. How was she to know that Tohru would end up at her door the next day in human form, offering to be Kobayashi's maid, protector, and one true love. Now on top of her everyday job, she has to help Tohru acclimate to the human world.
