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 not every school has a set that's 
been passed down through years like ours.
ولا تملك كلّ مدرسة مجموعتها الخاصّة
.الّتي تمّ تمريرها عبر سنوات مثلنا
und nicht jede Schule
hat wie uns eins im Etat.
y no todas las escuelas
tienen unos como nosotros.
y no todos los institutos
tienen unos como nosotros.
Ça se transmet d’année en année
chez nous, mais chez vous…
e non tutte le scuole possiedono un set che
viene passato di anno in anno, come nella nostra.
e nem todo colégio tem 
um herdado como o nosso.
и в школьных кладовках 
вряд ли получится отыскать такое добро.
