Tokine Amino is a young and overloaded CEO's secretary at a talent agency. She is unexpectedly taken to a weird parallel universe governed by a flying piglike monster while cleaning one day. Hacchin, the creature, reveals that this realm is called "Quizun," and she alters her clothes before adding that she cannot escape until she solves a riddle in five minutes. While Tokine maintains a relatively cool demeanor and solves the riddle, Hacchin notices her talent and determines the two will meet again. Tokine is now at risk of being sent to Quizun at any time, along with everyone else in her area.
