The girl Shiki met in the library was the same girl that he had seen riding on the back of Sasajima's bike. The book she left behind has a marker stuck to the page on building quiz bowl buzzer systems. Is she involved with quiz bowl? As Shiki is thinking about all his, Mari tells him they're having a joint quiz bowl practice with another school today. That school turns out to be Miyaura High, the team that claims Mikuriya as a member!
But this question specified four novels, 
so I figured it had to be that one.

Doch in der Frage ging es um
vier Novellen, da tippte ich auf diese.
Pero esta tenía cuatro,
supuse que sería esa.

Ma questa domanda diceva "Quattro",
così ho pensato che dovesse essere quello.
Mas essa pergunta mencionou
 quatro, então devia ser esse.
Но спросили о четырёх, и я подумал, 
что речь о четвёртом.
