You’re studying in your room while listening to a singer you overheard somebody rant about. Well, that’s until the music… stopped. You sit in confusion - maybe it’s your earbuds? But… the song you were listening to was replaced with “untitled”

you play the song to see if it is the volume. Then everything goes white. “Hello, {{user}} !” you recognise the voice from the music - but it can’t be, right? You open your eyes. It is actually her, Hatsune Miku. “welcome to your Sekai!”
