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...
Ashiya-san, he's a total otaku, isn't he?!
!آشيا-سان، إنّه أوتاكو بكلّ تأكيد، صحيح؟
Ashiya-san, der ist der krasse Otaku, oder?
Ashiya-san, es un otaku, ¿no?
Ashiya, ese es un friki, ¿no?
Mikuriya est grave un otaku,

Ashiya-san! Quello è un otaku fatto e finito, vero?!
Ashiya, ele é um otaku
 por completo, não é?
Ашия, он же настоящий гик, да?!
