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...
That's why I don't want to get 
chummy. I won't show any mercy.
.لذلك السّبب لا أريد أن أصادقه
.لن أظهر أيّ رحمة
Deshalb will ich nicht weich werden.
Ich zeige keine Gnade.
Por eso no quiero ser amigo suyo.
No mostraré piedad.
Por eso no quiero ser amigo suyo.
No mostraré piedad.
Je veux pas sympathiser avec lui.
Je le ménagerai pas.
Ecco perché non voglio fare l'amicone.
Non avrò alcuna pietà.
Por isso não quero intimidade.
 Não vou ter misericórdia.
Поэтому я не стану ему дружком 
и не буду его жалеть.
