The dragon maid. By which we mean a maid who is a dragon. She’s from the Chaos faction and is capable of utilising magic to perform such tasks as “perception-blocking”, repairing damage she may have caused, or transforming into a human girl. 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. She is commonly mistaken for a cosplayer due to her attire. A running gag involves her attempting to feed Kobayashi pieces of her tail with her cooking as a sign of affection.
