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.
I know you both did everything you could.
أعرف أنّكما بذلتما قصارى جهدكما
Mir ist klar, dass ihr beide getan habt,
was ihr konntet.
Sé que hicieron todo lo que pudieron.
Sé que hicisteis todo lo que pudisteis.
Je sais que vous avez tous les deux
fait tout votre possible.
So che sia Alma che tu, Akira, 
avete fatto il massimo...
Sei que vocês dois fizeram
tudo o que podiam.
Я знаю, что вы сделали всё, что смогли.
