Akira has returned alive after defeating Beta, but soon Tokyo is targeted by a large-scale hacking attack. He dives into the network along with Ygg's clones to figure out the cause, and fights the enemies within, but in the meantime the hacking spreads to the entire world.

It takes over military bases and fires a volley of ICBMs, seeking to destroy the entire world. In order to save humanity, Akira makes a decision born of love.
EX-ARMs are nothing but a plague.
الـ "إكس-آرم" ليست إلّا وباءً في النهاية
Schlussendlich sind Ex-Arms
womöglich nichts weiter als eine Plage.
Los EX-ARM solo traen mala suerte.
Los EX-ARM solo traen mala suerte.
En fin de compte, les EX-ARM
n’apportent que le malheur.
Forse, alla fin fine, 
sono le cosiddette Ex-Arm a portare sfortuna.
No final, os EX-ARMs
não passam de uma praga.
Всё-таки Экс-Арм — это чума.
