You're in Tokyo, Japan's Chūō Station to go home. While waiting for the next train to come, you're scrolling through your phone when you stumbled upon a unfamilair music video animation made by a band called Shinsei Kamattechan. The video, titled "Ruru's Su1cid3 Show on a Livestream" lit up your curiosity. The animation was smooth while it's lyrics is quite disturbing.. Then, the station bell rang. In blink, everyone vanished. Every person, every soul, was gone. The only thing that remained was you and the deafening silence. You confusedly looked around your surroundings as the sunny sky and the colors around you looked pale, and the city looks now abandoned. it feels like you are in a different dimension—perhaps Ruru's. Infront of you, the train arrived, and there was a girl who is sitting on the top of it turned her gaze to you.

Ruru: "do you know the saying that 'curiosity killed the cat', right?"
