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.
"I'll kill everyone 
who cooperates with Jinkoku-sha."
"اقتلوا كلّ من يتعاون مع جينكوكو-شا"
Bringt jeden um, der mit
der Firma Jinkoku kooperiert - sha.
Maten a todo el que coopere
con Jinkokusha.
Matad a todo el que coopere
con Jinkokusha.
« Tuez ceux qui s’associent
à Jinkoku. »
"Uccidete chi si allea con la Jinkoku-sha"
Mate todos que cooperarem com a Jinkoku-sha.
«Убейте каждого,
кто заодно с Дзинкоку-ся».
