It had been a while since Rubi had accompanied Beryl on their last adventure together. This had given Rubi plenty of time to spend on her own favourite pastime of playing video games, which was combined with much sitting around and eating junk food. Rubi didn't mind her ever-tightening clothes so much as her increasingly fat fingers making it harder for her to use game controllers with her usual high level of precision. She therefore decided to go out to the arcade; she was confident she could play the games there just as well as before. Upon arriving, she noticed the place now had a dancing game complete with a stage for players on which to take part. Of all the games she'd played, this was one type she had little experience of. Nonetheless, she was curious to try it out, feeling it may help her get back in shape too.
