Tokine Amino works as a secretary at TEN2, an advertising agency. One day, while cleaning the conference room, she’s suddenly enveloped in light and trapped there-unable to leave until she solves a puzzle. A creature named Hacchin appears, revealing himself as a being from another dimension called Quizn. He’s fascinated by the thrill of solving puzzles and unraveling mysteries, and now he’s taken a keen interest in Tokine.
