I, Tsushima (ONA)

The story centers on a woman who is getting on in years, but all her cats think she's a man so they call her Ojii-chan. One day a brazen cat named Tsushima appears in Ojii-chan's yard.

Short collaboration anime between Ore, Tsushima and Na Mo Naki Nezumi , released on the Asmik Ace and Na mo Naki Nezumi YouTube channels.

Two loose and cute cats, Riri and Popo, go on short animated adventures based on “enriching everyday life with everyone’s geek activities and promotions.” Riri is a "menhera" (mentally unstable) cat not blessed by the idol she supports while Popo is an airheaded cat who is cute in a devilish way. Otakuchanzu is the first anime to be originally created for TikTok.

The manga is set in Matsuyama City in the southwestern prefecture of Ehime on Shikoku Island during the Showa 40s era (1965-1975). The Onda family includes the big sister Sachiko who is a passionate fan of the idol Hiromi Dō, the little brother Takushi who is terrible at arithmetic, the father Yoshito who works at a factory and is a Yomiuri Giants baseball fan, the mother Natsuko who wants to build a house for the family, and the newest addition — a cat named Mii.
