A flyer from this year's AnimeJapan 2017 event revealed on Thursday that the television anime adaptation of Iqura Sugimoto's Nana Maru San Batsu (literally, "7 O 3 X" or "7 Right, 3 Wrong") manga will get 12 episodes. The flyer also revealed the anime's official title: " 7O3X Fastest Finger First ."

The anime will premiere on NTV in July.

Masaki Ōzora ( 12-Sai: Chiccha na Mune no Tokimeki ) is directing the anime at TMS Entertainment. Yuuko Kakihara ( Orange , Digimon Adventure tri. ) is supervising the anime's scripts. Makoto Takahoko ( Thunder Jet ) is drawing the character designs.

The flyer describes the series:

The last thing freshman Shiki Koshiyama expected was to be asked to join the Bunzo High School "New Student Fast Finger Quiz Championship." A bookwork at heart, he hates being the center of attention and shudders at the mere thought of participating. To add insult to injury, his classmate Mari Fukami overwhelms her competition by pressing the buzzer even before the entire question is read. "It's too late to hit the buzzer after you know the answer. A split second is all it takes to determine who wins or loses," she declares. After observing Mari for a while, Shiki discovers a way to determine the answers to a quiz. His world expands as he meets colleagues and senior members of the Quiz Club, as well as their formidable rival Chisato Mikuriya. He experiences the joys of answering correctly and the frustrations of not getting to the buzzer quickly enough. He and his colleagues hone not only their knowledge, but also various techniques as they pursue victory in the world of competitive quiz. Shiki Koshiyama is about to dedicate his teenage years to quizzes. You too should try becoming the next quiz champion!
