Saki Sonoda, a lazy middle schooler, is tasked by her older sister Moe, a university robotics researcher, to educate two quirky helper robots, Ato and Suu, who lack common sense due to their underdeveloped AI. Ato, a clever but cheeky robot with pink pigtails, and Suu, a strong but naive robot with blue fluffy hair, crash into Saki’s life, literally breaking her wall. Their chaotic antics disrupt Saki’s routine as she reluctantly takes on the role of their caretaker, lured by the promise of a hefty reward. The trio’s dynamic grows more hectic when Pon-chan, a mysterious alien disguised as a tanuki, joins them, adding extraterrestrial mischief to their daily adventures. Together, they navigate comical mishaps while aiming to prepare the robots for a prestigious robotics contest.
