I like it. It's still ongoing right now so the reviews are not that firm. I think it will develop into a greater storyline. There are still many more characters to be introduced. The characters are very likable. Although it's about 'quizzes' it isn't boring. It's more about the energy of the competition and the various play styles and the cooperation of the members of the quiz clubs.
The main character is a literacy lover, but he will develop furthermore. Plus the art style is good. The show also has a comedy vibe going on. And the music sure gets you excited.
I recommend to anyone who enjoys a good laugh and less romance and more games.
