Usagi, Minami, and Tokiwa are at the Omiya Park as a pep rally for the Railway Quiz Championship. Nishiki and others from theSaint Omiya Girls High show up and challenge them to a Railways quiz. The competition leads to an UWAAR match…but what exactly is UWAAR?!
I'm not sure what it is, but as long 
as you're willing to lead it, I'm game!
لا أدري ما هذا، لكن ما دمتِ راغبة
في قيادة ذلك، فأنا موافقة
Also ich weiß nicht, was das ist,
No sé qué es. ¿Podrían mostrarnos?
No sé qué es. ¿Nos lo enseñáis?
Non so bene cosa sia, ma se volete fare quello 
per me non ci sono problemi!
Não sei bem do que fala,
mas vão participar?
Не знаю, что это за игра, но я в деле,
раз сама предлагаешь.
