Tokine Amino is a young, overworked secretary for a talent agency CEO. While cleaning one day, she's abruptly pulled into a bizarre alternate world ruled by a floating pig-like being named Hacchin. He tells her this place is called "Quizun" and changes her clothes before declaring she can't leave unless she solves a puzzle within five minutes. Though startled, Tokine stays composed enough to solve it. Impressed, Hacchin hints they'll meet again. Now Tokine faces the constant threat of being whisked away to Quizun without warning-and anyone near her might get dragged along too.
