After multiple failed attempts at becoming a high school teacher, Yamashiro Koyomi finally receives unexpected news of passing the exam. To her surprise, she realizes she mistakenly applied for an 'animal trainer' position at a unique school in Aima Prefecture, dedicated to grooming inexperienced UMA creatures. Despite her initial doubts, the school principal offers her a deal: excel in her role for a year, and he'll recommend her to other schools. With zero training experience, Koyomi faces the challenge of not only teaching but also nurturing an UMA. Can she help this creature evolve and secure a chance to switch schools in this unconventional teaching journey?
