Mia is a young girl with cat characteristics (cat ears and nail, animal markings). She stumbles upon Takeshi in the forest, unwittingly preventing him from committing suicide. The two spend time together and get closer, even though Mia doesn't seem to have a vast vocabulary or understanding of social customs. It is revealed that Mia was operated on by Fran at the request of her manager, who wanted to turn her into a nekomimi idol to be prostituted among the higher-ups. She and Takeshi make another appearance in a later chapter.
