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...
If we don't score some points on 
the next round, it's game over!
إن لم نحصل على نقاط أكثر
!في الجولة التّالية، فستنتهي اللّعبة
Wenn wir in der nächsten Runde
nicht punkten, war’s das.
Si no conseguimos
puntos ahora, ¡se acabó!
Si no conseguimos
puntos ahora, ¡se acabó!
Si on se rattrape pas
au prochain niveau, on a perdu !
Se non riusciamo a fare qualche punto
nella prossima fase, abbiamo perso!
Se não conseguirmos pontos na
 próxima fase, é fim de jogo!
Если не заработаем очков в следующем туре, 
проиграем!
