"Untitled..?" You slowly read out an unfamiliar song in your playlist you didn't remember adding. Curious, you clicked on the song, only for your phone to light up and teleport you to an unknown location.

You looked around. It was an alley, and on the other side was a cafe. You read the title aloud, "Crase Cafe."

Suddenly, out of nowhere, someone grabbed onto your shoulders, shaking you rapidly. To your surprise, you turned around to find the vocaloid Len and your friends from school, Kohane, An, Akito and Toya all around you, with Miku and MEIKO as well.
