Ok guys, I didn't mean an argument to happen, with that link I showed, just treat it like Nekomura Iroha and her voice provider speculations, there was a sample of her voice provider singing and AHS never revealed the voicer.

But the "voicer" for VY2 must have sung some Vocaloid songs, someone found them and had VY2 sing those songs to see if two and two went together. Plus the person who uploaded it commented who the voicer is.
