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 you guys win, I'll give 
you anything you want.
.إن فزتما، سأعطيكما ما تريدانه
Wenn ihr gewinnt,
mach ich alles, was ihr wollt.
Si ganan, les daré
todo lo que quieran.
Si ganáis, os daré todo lo que queráis.
Si vous gagnez,
je vous file ce que vous voulez.
Se vincete voi, vi darò tutto quello che volete.
Se vocês vencerem,
 dou o que vocês quiserem.
Если вы, парни, победите, 
я сделаю всё, что пожелаете.
