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 was just a powerless human 
who couldn't do anything by himself.
كنتُ مجرّد بشريّ عاجز لا يستطيع
فعل شيءٍ من تلقاء نفسه
Ich war bloß ein einzelner Mensch,
der nichts ausrichten konnte.
Era un ser humano
que no podía hacer nada especial.
Era un ser humano
que no podía hacer nada especial.
Je n’étais qu’un humain,
Ero un semplice essere umano
Eu era apenas um humano impotente,
que não conseguia fazer nada sozinho.
Я был ни на что не способным человеком.
