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!
