Kazuma Saiki is the CEO of Saiki Corporation, an A-rated agricorp operating in southeast Asia, and headquartered in Cairns Australia. The corporation meets the qualifications for extraterritorial status, but this has been blocked by Mitsuhama. Mr. Saiki was also the head of the Saiki-rengo (yakuza syndicate), which controlled all of the gumi (yakuza family) in Australia. Saiki consolidated his rengo circa 2042, and lost control to the Naheka-rengo in 2066.
