Ryun the Dragon Girl stays in the abandoned land of Izumo to keep away from other people. Her radiance is so bright that any normal person would have their eyeballs burnt to a crisp. Luckily, Oni have strong eyes which allows for them to interact with her unlike other species. Ryun wants to be accepted by other people, but she feels she was born into the wrong time period. With the help of a passing Oni, the player, she is able to acquire a Reversed Compass which can be used to travel into the future. With this compass, Ryun sends herself into a future where Dragon Girls aren't discriminated against. This provides her the opportunity to complete her ambition of having her own personal Harem.
