Hatsune Miku

Background
Hatsune Miku is an Eldritch creature, presumed to be something along the bloodline of Tarrant Hightopp or Willy Wonka. She was a singer and songwriter before being driven to insanity. It's assumed from her late-night ramblings on @hatsune-miku-official that she was abandoned by her best friend, referred to as Kiz.

As well as being the possesser of the Chaos equalling that of any A-tier god, such as Pluto, she has the added abliity to possess the bodies of any able-bodied Official.

List of Possessed Officials
Those already within her grasp include:

Springtrap

Funtime Freddy

José Carioca

And several more that remain unfound.

More Background
Miku suffers from many of the symptoms of Antisocial Personality Disorder, such as a lack of carefulness for anyone other than herself and a distinct recklessness about the laws of the land. Her only non-brainwashed servant is Toadette, who also acts as a stress dog of sorts for Miku.
