At This Rate... It Really Will be War!.The US Government offers to assist in the fight against Sato, but the Japanese are reluctant to agree. The Japanese government offer some Japanese islands to Sato for the Ajin, but Sato angrily launches a nerve gas projectile to further assert his demands for full control of Japan. He gives the Japanese government 3 days to surrender before he launches all his missiles. Meanwhile, Sato's demands and game-playing cause dissension in his group as it will escalate their war, so most plan to desert him. The launch motivates some civilians to hunt down families of Ajin, including Kei's sister Eriko at the hospital. Kei intervenes to save her, but his IBM will not appear. Fortunately Kaito appears, accompanied by his fellow cellmate Kotobuki with his IBM to save them. After subtly telling Kaito to look after Eriko, Kei decides to return to Tosaki's group in order to stop Sato. The Japanese forces try a sneak attack on Sato but fall into a trap and are killed.
