The narrative centers around Gokudo, a self-serving and morally ambiguous treasure hunter who stumbles upon a mysterious girl named Ruu. Ruu possesses a unique ability to transform into a powerful warrior when kissed, a trait tied to her origins as a "Goddess of Destruction." Gokudo, driven by his greed and desire for wealth, decides to exploit Ruu's powers for his own gain, embarking on a journey filled with danger, treasure, and unexpected alliances.
