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...
I'd rather not have to 
reveal my hand here...
...أفضّل ألاّ أكشف عن قدراتي هنا
Ich sollte lieber mal
den Ball flachhalten …
No me gustaría revelar mi mano aquí…
No me gustaría revelar mi mano aquí…
Je voulais pas
abattre mes cartes maintenant…
Non vorrei dover svelare qui la mia mano...
Prefiro não mostrar do
 que sou capaz aqui...
Не хотелось бы раскрывать свой козырь...
