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.
We must seal it away forever 
by our own hands.
علينا ختمه للأبد بأيدينا
Wir müssen es für immer und ewig
unschädlich machen.
Tenemos que deshabilitarla para siempre.
Tenemos que sellarla para siempre.
Nous devons la sceller à jamais
de nos propres mains.
Dobbiamo sigillarla per l'eternità
 con le nostre mani...
Devemos selá-lo para sempre
pelas nossas próprias mãos.
Мы должны лично навсегда
от него избавиться.
