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!
That leaves Journey to the West 
and The Plum in the Golden Vase.
"وبهذا تكون قد تبقّت روايتا "رحلة إلى الغرب
."و"برقوق المزهريّة الذّهبيّة
Also Die Reise nach Westen
und Die Pflaumenblüte in der goldenen Vase.
Quedan Viaje al oeste
y El ciruelo en el vaso de oro.
Quedan Viaje al oeste
y El ciruelo en el vaso de oro.
Rimangono "Il viaggio in occidente"
e "La prugna nel vaso d'oro".
Com isso resta Jornada para o 
Oeste e Ameixa no Vaso de Ouro.
«Путешествие на Запад» 
и «Цветы сливы в золотой вазе»...
