This anime adapts Kazuo Hara's comedy manga, where mascot characters reside and work alongside humans. Agencies have been established to train mascots for babysitting duties and subsequently place them with families. Noramimi is a mascot assigned to the Hello Kids branch office #59. Unfortunately, because he was born into a demon (oni) family, no family wishes to adopt him, leaving him stranded at the agency. Source: ANN, Moon Phase
