Zero shocks both his allies and enemies by agreeing to join Nunnally’s Special Administrative Zone (SAZ). He enters a secret negotiation with Suzaku and other Britannian officials, proposing his own exile in exchange for delivering one million Japanese to the SAZ. During the opening ceremony, a massive smoke screen is deployed, and as it clears, every participating Japanese person—including a dog—is revealed to be wearing a Zero costume.
