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...
Come on, Maririn. Back to work, okay?
هيّا يا ماريرين. لنعد للعمل، موافقة؟
Komm schon, Maririn.
Die Arbeit ruft!
¡Vamos, Maririn! A trabajar, ¿sí?
Vamos, Maririn. A trabajar.
Tiens bon Maririn,
c’est le boulot. OK ?
E dai, Maririn. È il nostro lavoro, no?
Vamos, Maririn. De volta
 ao trabalho, não é?
Да ладно, Маририн, 
работа есть работа! Да?
