第1話: Nanoが猫を追って腕を失い、YūkoとKōjirōが学校で混乱を引き起こす

While chasing after a cat that stole her breakfast, Nano runs into a student and blows up and finds herself up on a roof with a missing arm. Yūko goes through desperate means to keep her octopus sausage from being sullied, while Kōjirō Sasahara makes a scene at the school's opening ceremony over bringing his goat to school, only to be shot and reprimanded by Misato Tachibana, and Yūko tricks Mio into pressing the fire alarm. Later, Nano begs her creator, the Professor, to remove the noticeable windup key on her back, but she refuses because she thinks it is cute. (Source: Wikipedia)
