第 4 集: Akira 駕駛 Ogre 外骨骼與 Elmira 的 Bibot 交戰，同時恢復記憶。

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. (Source: Crunchyroll)
