For citizens of the Ken Empire, justice is a myth. Lord Keiro, the deranged Shogun of the Imperial Army, blazes a trail of terror across the countryside in search of the sacred sword that will make him a god. Standing in his way is Taito, an omnipotent star reborn in human form—a young hero who vows to use his celestial strength to avenge those slaughtered by the villainous Shogun. Taito's mystical powers steer him toward a violent showdown with Keiro, and if used recklessly, his newfound abilities could shred the very fabric of his being. To master the art of control and become a heroic martial artist, Taito must seek the guidance of others like him: the seven star-born warriors with the strength to shatter a corrupt empire.

Every 60 years, the heavens conduct a sacred ritual called ETM12. This custom involves selecting worthy Eto-musume—celestial beings representing different animals—to become one of the members of the Chinese zodiac, or Eto-shin. However, since the first ETM12 two thousand years ago, the original batch of Eto-shin reigns with no one being able to replace them. Nyaa-tan is a cat Eto-musume who aspires to become a member of the zodiac in the ongoing ETM12. Fulfilling her ambition requires her to secure 12 seals, one for each Eto-shin. To that end, she must win various types of battles using Sol/Lull—divine energy created by people's positive emotions. This task is not easy however, as her powers as an Eto-musume are far below the abilities of a single Eto-shin. As such, she needs a constant source of energy. But in a chance encounter, Nyaa-tan meets Takeru Amato, a man who has just transferred to the apartment where she is secretly staying. To Nyaa-tan's delight, Takeru discovers that he gives out high quality Sol/Lull—something that sets him apart from most people. With this, the story of Takeru and Nyaa-tan begins. As Takeru supports Nyaa-tan in her dreams, he meets the Eto-shin and begins to uncover a mysterious past. [Written by MAL Rewrite]
