The only way to beat the giant Beta is via direct attack to the brain, forcing Ogre into a very perilous situation. Auctioneer risks his life to locate the brain, and Ogre uses Number 11 to take it out and defeat Beta.

He reunites with the Squad and celebrates, but his joy would be short-lived.
Thank goodness. Good job, Akira.
حمداً لله، أحسنتَ يا أكيرا
Gott sei Dank … Akira hat alles gegeben …

Qué alivio.

bom trabalho, Akira.
Слава богу... Ты молодец, Акира.
