Shuuichi Sugino is frequently bullied at school. His home life is equally challenging due to his strict mother, Miho, often ridiculing him for his poor grades. Following another such incident, Shuuichi discovers that his phone contains a mysterious app, which claims to grant the user's wishes without any negative consequences. Intrigued, Shuuichi decides to test the app by asking his mother to take off her shirt—which she surprisingly does. As the boy continues to test the limits of the app, he grows increasingly depraved and soon sets his sights on more than just his mother.
