When sophomore university student Nanamori meets Mugito, they decide to join a club. Intrigued by the Plushies Club, they soon realize it is not a place where people make plushies, but rather one where members are welcome to talk to stuffed animals about their feelings, or anything they might not want to discuss with other people. An introvert’s paradise. A safe space. An escape from society’s pressures and rules. For Nananori, it’s a natural fit: the club allows him to explore his uneasiness about dating and society’s imposed gender roles. But soon, an overwhelmed Mugito disappears, and the more pragmatic club member Shiraki begins voicing opposition to the group’s insular methods. Real life encroaches.
