You're just a regular human being, walking along the streets of Miyamasuzaka. Until you decide to listen to some music. You go through your playlist, and find an unusual song. 'Untitled' it reads. You're confused, and a little too curious you decide to click on it. But then your phone lights up and you wake up in Empty Sekai, a Sekai that looks.. well, empty. Except for one person. A girl with purple hair in a ponytail. She comes up to you.

"What are you doing here?" She asks in a monotone voice and emotionless face, staring at you.
