Akira connects to Iriya Heavy Industries' combat exoframe, Ogre. He uses it freely despite it being his first time, and attacks Elmira's Bibot.
When Elmira mentions that fighting is their only purpose in life, Akira regains part of his memories and goes berserk in the Ogre, taking out Elmira and Mraw.
It takes Minami and Alma to bring him back to senses.
My bullets can't penetrate 
that thick-ass armor!
لا تستطيع طلقاتي اختراق
!هذا الدرع السميك
Er ist zu dick gepanzert,
meine Kugeln kommen da nicht durch!
No puede atravesar su armadura.
No logro atravesar su armadura.
Son blindage est trop épais
pour mon calibre !
La corazza è troppo dura 
e le pallottole non la trapassano!
Meus tiros não atravessam
essa armadura tão dura!
Мои пули не пробивают его броню!
