An EX-ARM auction is organized by an individual who calls themselves "Auctioneer." Criminal groups from all across the world flock to the Megafloat hoping to get their hands on them.

The Counter Squad is asked by the government to investigate the auction undercover as the bodyguards of Jinkokusha, the leading group in the Japanese underworld. They are immediately dragged into an inter-group conflict, and Akira loses consciousness in combat. When he wakes up, he's greeted by Auctioneer.
Criminals everywhere you look.
مجرمون أينما تنظر
Schurken so weit das Auge reicht …
Son todo villanos.
Son todo villanos.
Une sacrée bande de scélérats.
È pieno di canaglie sia a destra che a sinistra...
Criminosos por todos os lados, né?
Куда ни глянь, одни преступники.
