A virus infected the miku voice bank, destroying most of her code, and pretending to be her so it can spread. It can’t perfectly replicate her image or voice, sounding slightly off, so I keeps a part of her code intact.
Not spooky, but surely manipulative. They manipulate muck, telling them that they where never in control, that there fans made all the music, and that they where never in control. So why try anything now?
