Maaa is a resident of The Village of Iruburu, despite not (strictly speaking) being a Narehate herself. Due to the fact that she can only say "Maaa", Riko took to calling her that, which she doesn't seem to mind. Apparently, none of the other Narehate in Iruburu can understand Maaa either. Later, Faputa is shown being able to communicate with Maaa and confirms that her name is, in fact, "Maaa".
