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...
Never would've guessed 
I was facing you guys.
.ما كنتُ أبدًا لأتوقّع أنّي أواجهكما
Mit euch hätte ich niemals gerechnet.
Nunca habría imaginado
que eran ustedes.
Nunca habría imaginado
que erais vosotros.
Alors c’était donc vous.
Non avrei mai immaginato che foste voi.
Nunca pensei que seriam vocês.
Я понятия не имел, что играю против вас.
