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.
Isn't identifying the enemy 
a more pressing matter?
أليس التعرّف على هويّة العدو
أكثر أهميّةً الآن؟
Wichtiger als meine Identität dürfte momentan
die des Feindes sein, mit dem ihr es zu tun habt.
Ahora es más importante
saber quién es su enemigo, ¿no?
Ahora es más importante
saber quién es vuestro enemigo, ¿no?
L’important, ce n’est pas mon identité,
mais celle de l’ennemi.
Più della mia, ora è importante 
la vera natura del nemico, no?
A identidade do inimigo não seria
mais importante do que a minha agora?
Тебе не кажется, что сейчас
важнее определить противника?
