Quizzes and more quizzes. They could be fun if the watchers feel the same interest in both the questions and the participants. If you don't like quizzes shows, then you immediately will consider Nana Maru San Batsu (Fastest Finger First) as a total waste of time, and the only fastest finger that you will end seeing is yours when you "change" for other show.
I had been thinking how to rate this anime. Should I evaluate the questions, should I rate the quizzes modules, should I rate the characters? After a lot of thinking, I considered there is nothing to measure here.
The story is the typical "nerd" with his glasses and every detail (Koshiyama). The destiny gave him the possibility to talk with a group of persons and ended joining the quizzes club from the school because Mari Fukami asked him. Then the story focuses on the game meetings against other schools, where Koshiyama finds a rival (Mikuriya). The climax appears when Koshiyama can't press the button faster, the inability to answer a certain group of questions, and when he challenges Mikuriya. So they spend a couple of minutes when Koshiyama starts analyzing the problems and figures a possible answer. That's all the story, nothing more. There are some unconcluded parts, for example, Mari's brother.
The characters are the typical members of a school club with nothing special on them. They are in that club because they like it and will participate in the events because why not? The background of most of the characters they like quizzes, they study them, they need faster fingers, and ¡hey I found a rival!.
The art and the music are what I consider standard nothing impressive here and nothing to complain about it.
Finally, the characters do a little monologue when they try to figure an answer. It is the same repetition from question to question so you could end tired even if you like quizzes. Will I recommend this show to you? Maybe but you will consider it tedious.
