Yamazaki gets orders to go undercover, and attempts to sneak into the Anti-Foreigner Faction hideout. His job is to find out what missions faction members are being given and to apprehend Kotaro Katsura “The Unstoppable” along with all his officials. Yamazaki uses his overwhelming blandness to sneak in without drawing any suspicion. But in order to become an Anti-Foreigner Faction member, he needs to pass an interview with Katsura and a written employment exam.
I can't fight and leave my back open to
someone with a suspicious background.
No podemos pelear lado a lado con 
alguien cuyo pasado no conocemos.
Não posso confiar a minha retaguarda
 a alguém cujo passado eu não conheça.
