Koshiyama Shiki, a new enrollee at Buzou High School, is a bookworm and quite the introverted type. He even eats lunch in the school library. But at the ceremony to welcome new students, he found himself volunteered to participate in an impromptu quiz meet by the quiz bowl circle's leader, Sasajima Gakuto. Shiki knows the answers to all the questions, but it unable to buzz in quickly enough... until he notices a change in his classmate, Fukami Mari, who starts buzzing in to answer questions before they've even been read!
But I was the class librarian through 
all three years of middle school!
لكنّي كنتُ أمين المكتبة خلال السّنوات 
!الثّلاث كلّها في الإعداديّة
Dabei war ich doch in der Mittelschule
immer der Bibliothekar!
¡Pero yo fui el bibliotecario
durante mis tres años de secundaria!
¡Pero yo fui el bibliotecario
durante los tres años de secundaria!
Au collège, c’était toujours moi
le responsable de la bibliothèque !
Ma io ho fatto il bibliotecario
per tutti i tre anni delle medie!
Mas eu fui o bibliotecário da turma
 durante os três últimos anos!
Блин, я же отвечал за библиотеку 
все три года средней школы!
