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!
Joint practice, huh? I wonder 
which school they're coming from.
تدريب مشترك؟ أتساءل من أيّ مدرسة 
.سيكون الفريق القادم
Ein gemeinsames Training, ja?
Welche Schule wird es wohl sein?
¿Un duelo?
Me pregunto qué escuela vendrá.
¿Un duelo?
Me pregunto qué instituto vendrá.
Un entraînement collectif ?
Qui pourrait bien y avoir ?
Un allenamento congiunto, eh?
Chissà di che scuola sarà la squadra.
Treino conjunto, é?
 Qual colégio será que vem?
Практика, значит? 
Интересно, с какой школой?
