Etotama (えとたま; "Chinese Zodiac Spirits") is a Japanese anime television series produced by Encourage Films and Shirogumi, which aired from April 9 to June 25, 2015. A manga adaptation began serialization from December 2013 in ASCII Media Works's shōnen manga magazine Dengeki Daioh. A 30-minute original net animation (ONA) episode titled Etotama ~Nyan-Kyaku Banrai~ premiered on May 25, 2021.

The anime's story revolves around Nya-tan, the cat of Chinese astrology who wants to become a member of the Chinese zodiac. Nya-tan is simple and suffers from memory loss, and she tries various idiotic ways to become a member. She meets Takeru Tendo, a high school student who lives alone in Akihabara, and becomes a freeloader at his house. Little by little, she gets closer to her goal.

Sol/Lull is the source of the Eto-musume's life force. Sol/Lull is the embodiment of proper human emotions, it's a type of energy only humans possess, like Takeru Amato. Every time a human feels grateful, Sol/Lull appears. And when Sol/Lull collects into an Eto-musume's soul, their Etotama, they transform from adult mode, the form that allows then to exist in the human world, to the form that allows them to fight in the Eto world, pretty mode.

A spin-off anime called Etotama -Kids was presented at the Content Tokyo 2016 tradeshow.
