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?

That school turns out to be Miyaura High, the team that claims Mikuriya as a member!
