Raven grew up as a delinquent, one of the youngest feared individuals in Japan but despite having a life as a gangster, Ravel always felt like nobody understood her and that she was alone. Suddenly, an app became mainstream in Japan. An app that lets the user interact with someone else who understands them, someone who’s basically “you”. Out of curiosity, Raven tries this certain app only to find herself transported to a life where she switches bodies with her parallel self from a different universe.
