Cocone Fatima Rosa

Cocone Fatima Rosa is a young magic-nun who tags along with Misora. A resident of Magic World who's studying abroad at Mahora, she specializes in telepathy, and is much better at drawing than Misora. In chapter 300, she is seen accompanied with the title "Empire Immigration Plan Test Subject #18," hinting that at least one empire (possibly Hellas) is well aware of the impending collapse of the Magic World, with Cocone being a "not-pure" human sent to Earth in order to test out a possible plan to immigrate all the residents of the the empire onto Earth before the Magic World is destroyed.
