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.
But I can say that Natsume Shuichi is content 
just knowing you have that desire.
لكن يمكنني أن أعرف أنّ ناتسومي شويتشي
راضٍ بمجرّد امتلاكك لهذا الشعور
Aber ich bin sicher, dass Natsume
Shuuichi froh wäre zu sehen,
pero creo que tus sentimientos
pero creo que tus sentimientos
mais ce désir que tu chéris
ma basta anche quel tuo pensiero
Mas sei que Natsume Shuichi está contente
Однако с уверенностью могу сказать, что
Сюити Нацумэ доволен твоим желанием.
