Otaku-chans

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.
