Etotama: Nyankyaku Banrai

In a world where the ongoing struggle between the Zodiac signs has finally subsided, a new chapter begins as peace reigns. However, the unexpected arrival of Na-tan, an Eto-musume representing the Zodiac, leaves both the twelve signs and her fellow companions in a state of confusion and curiosity. Na-tan’s innocent and cheerful demeanor brings a refreshing energy, especially to Nya-tan, who finds joy in her presence.

Yet, tranquility is soon overshadowed by a dark omen when Chu-tan appears, alerting everyone to a potential catastrophe. With the ominous words, "The seal… has been broken," the mystery deepens around Na-tan and the ancient deity that stirs beneath the surface. As the characters navigate this new threat, they must unravel the secrets surrounding their world and the significance of Na-tan's existence.
