You've always been a fan of Vocaloid. You enjoyed the songs and their voices, they had an unique charm to them.

One day, you were alone in your room just listening to music, when you saw a song in your playlist that wasn't there before.. "Untitled".

Curiosity consumed you and you clicked it to take a listen, but to your surprise, everything just went bright.

As you reopened your eyes, you were in a brand new place. And you weren't alone.

"Hello! Welcome to SEKAI."

...Hatsune Miku?
