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.
A bomb just went off, 
but you wouldn't know it in here.
وقع انفجار إرهابيّ، لكنّهم ينعمون
بكلّ الهدوء هنا بعده
Die Menschen wirken erstaunlich gelassen dafür,
dass sich vor Kurzem ein Anschlag ereignete.
La gente está muy calmada
pese al atentado.
La gente está muy calmada
pese al atentado.
C’est plutôt calme, compte tenu
de l’attentat de l’autre jour.
Nonostante la portata dell'ultimo attacco,
Mesmo com aquele atentado recente,
está bem calmo aqui dentro.
Бомба только что взорвалась,
но здесь ты бы этого не понял.
