Etotama

Every 60 years, the heavens hold ETM12, a sacred rite that chooses promising Eto-musume—animal-themed celestial beings—to join the Chinese zodiac as Eto-shin. Yet ever since the inaugural ceremony two millennia ago, the same original Eto-shin have remained in power, with no one managing to take their place.

Nyaa-tan, a cat Eto-musume, throws herself into the current ETM12 with the goal of earning a spot among the zodiac. To succeed, she must collect twelve seals—one from each Eto-shin—by prevailing in a variety of battles fueled by Sol/Lull, divine power born from people’s positive feelings. Outmatched by the strength of the Eto-shin, she needs a steady supply of that energy, and finds it unexpectedly when she crosses paths with Takeru Amato, a new tenant in the building where she’s been secretly living. Takeru’s unusually strong Sol/Lull becomes her lifeline, drawing him into encounters with the Eto-shin and toward hints of a hidden past.
