Plot
Reo Mishima, who has advanced to the finals of the live quiz show Q-1 Grand Prix, is on the verge of winning the one-on-one buzzer quiz, in which the first to answer seven questions correctly wins. Three incorrect answers result in elimination. However, in the final moments, his opponent, Kizuna Honjō, presses the button before a single word of the question is even read, inexplicably guessing the correct answer, resulting in Mishima's defeat.
Novel
According to the author Satoshi Ogawa, he wanted to create a sports novel, but said that the "physical movements and beauty of the sport are lost" when you turn sports into a novel. The novel was inspired by Takushi Izawa after Ogawa was hooked by the videos of QuizKnock. He wanted to create the quiz-related novel since around 2019, but started writing the novel around February of 2022 and finished the draft before the deadline in April. The quiz part was created by his friend Tamura Masashi. According to Ogawa, he chose to create a quiz-related novel because it is easy to adapt into a novel, as quizzes are made out of words themselves, and he wanted to express the speed and tension of quiz competitions like those in sports through a novel. He also included the question and answer in the novel so that the readers can also answer the quiz in the novel, adding that he wanted the readers to answer at least one question correctly before or at the same time as the main protagonist.
