Sona Buvelle, Maven of the Strings
A human Champion in League of Legends usually played as a support. Originally from Ionia, she is now living in Demacia. She is known for being unable to speak verbally (communicates with the player telepathically), her calm music and equally calm demeanor, and her exposed large breasts.
She looks very similar to and is rumored to be inspired by Hatsune Miku.
