As Mari and Kouzuki Yuki are working at their part-time job in Akihabara to earn money for a buzzer set, Shiki and Inoue arrive in the area to train themselves with a quiz bowl game in the arcade. They're battling against a player called "Second Lieutenant Chisato" when Ashiya shows up, and the pair finds out that their opponent is someone they know quite well. Then a strange, somewhat suspicious character approaches the group...
Um... If it's okay with you...

Así que, si te parece bien…
Esto, si te parece bien…

Ecco... se ti va...
Bem, se você quiser...
Эм... Надеюсь, ты согласишься...
