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'll leave the future up to Akira and those two.
سأترك المستقبل على عاتقيّ أكيرا وعاتقيهما
Ich vertraue Akira und den beiden
unsere Zukunft an.
Le confiamos el futuro a Akira.
Le confiamos el futuro a Akira.
Je leur confie notre avenir.
Io affido il futuro ad Akira e alle sue compagne.
Deixarei nosso futuro com eles.
Будущее зависит от Акиры, Альмы и Игг.
