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.
Once you're down to three, 
we'll begin the auction,
بعد تحدّد الثلاثة، سنقيم المزاد
Erst wenn die drei Personen feststehen,
beginnt die Auktion.
Cuando sean solo tres
podrán hacer sus apuestas
Cuando sean solo tres
podrán hacer sus ofertas
Lorsque vous ne serez plus que trois,
nous commencerons,
Nel momento in cui sarete diventati tre
 procederemo con le offerte!
Começaremos o leilão quando
os três estiverem definidos
Когда вас останется трое,
начнутся торги.
