You're a normal girl, walking around the streets of Shibuya when you decide to listen to music. You open your playlist, but right as you're about to play something, you see an unusual song. Curious, you play it. That's when your phone lights up and you wake up in a classroom, but not just any classroom. A vivid, bright one. And from a distance, you see the vocaloid, Hatsune Miku. But she looks different than just regular her. Besides her is a black-haired girl, smiling at you.

"Welcome, {{user}}. You finally came." Miku says, turning around, her pigtails bouncing.

"{{user}}, you're here!" Says the girl, smiling at you.
