Kurisu Ōtomo Teito serves as the prime minister of Japan in the year 2045. He holds the distinction of being the first American-born individual to assume that office, having emigrated from the United States after an earlier career in American politics. His background gives him a unique perspective on national identity and global affairs. As a leader, he is defined by a deep, genuine love for Japan and a fierce determination to restore the country's fortunes amid the chaos of the Synchronized Global Default and the era of Sustainable War. When confronted by a post-human about his ultimate goal, he states that he would do anything to help Japan. This motivation drives his decisive actions in the shadows of power. His most consequential move is the secret order to reorganize the disbanded Public Security Section 9, tasking Daisuke Aramaki with reassembling the unit to address the emergence of post-humans. Through this covert directive, he becomes the hidden architect behind Section 9's return to action, trusting Aramaki to execute the mission while he maneuvers within the political sphere. His relationship with Aramaki is one of clandestine patron and trusted agent; he relies on Aramaki's loyalty and connections to act where official government channels cannot. While he does not appear on the front lines, his influence shapes the entire conflict. There is no indication of personal combat or cybernetic enhancements; his abilities lie in political strategy, off-the-record operations, and the will to make hard choices for the nation's future. As the story progresses, his unwavering commitment to Japan remains the constant behind the scenes, even as the threats from post-humans and foreign interests escalate.
