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!
And I'm the class librarian, 
just like Fukami-san, too!
!كما أنّي أمين مكتبة مثل فوكامي-سان أيضًا
Und ich bin der Klassenbibliothekar,
genau wie Fukami-san.
¡Y soy bibliotecario como Fukami-san!
¡Y soy bibliotecario como Fukami!
Et je suis de service à la bibli
avec elle !
E sono anche un bibliotecario
proprio come Fukami-san!
E fico na biblioteca como a Fukami!
А ещё мы с ней библиотекари класса!
