Tokine Amino is secretary to the CEO at TEN2, an advertising agency. At work she is widely admired, but only two friends at the front desk know she is a devoted otaku and tokusatsu fan. While tidying a conference room ahead of a meeting with a well-known animation company, she is engulfed in bright light and pulled into Quizun, a strange parallel world. There a small floating pig named Hacchin greets her and explains that she cannot leave until she solves riddles within a time limit. Tokine keeps her cool and cracks the puzzle, and Hacchin decides they will meet again. From then on she may be whisked back to Quizun at any moment, taking along anyone nearby. The result is a short-format mystery series.
