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...
No matter who I face, I'll show no 
mercy when I'm laying the smack down.
لا يهمّ من سأواجه، لن أظهر أيّ 
.رحمة عندما أبدأ القتال
Ganz gleich, wem ich mich stelle,
ich mache sie alle fertig.
Da igual a quién enfrente,
los venceré sin piedad.
Da igual a quién me enfrente,
los venceré sin piedad.
Quel que soit l’adversaire,
je me battrai sans pitié.
Non m'interessa chi sarà il mio avversario,
batterò tutti senza pietà.
Não importa contra quem eu jogue,
 vou derrotar sem misericórdia.
Кто бы ни играл против меня, 
я не стану поддаваться.
