Yoko Kayabuki

Kayabuki is a Japanese woman whose body has been partly mechanized, one of the many cyberized figures of her generation. Brown eyes sit beneath a fringe of dark hair, and she carries the composed bearing expected of a veteran head of government.

Her backers sell her to the public as a stern hardliner, an anti-corruption symbol meant to wash away the stain of the Yakushima scandal, and her cabinet draws an ultra-hawkish reputation. Beneath that packaging lies the role they actually intend for her: a decorative leader whose real power was supposed to rest with Chief Cabinet Secretary Takakura and his cabinet. She refuses to remain a puppet, choosing principle over survival even when doing so strips her of the office.

The ruling coalition, having kept its majority in the 2031 election, elevates Kayabuki to replace the previous premier once the Yakushima corruption affair poisons his administration. Two years after Umibozu troops storm Section 9's headquarters, she makes good on the bargain Daisuke Aramaki had reached with the earlier government and restores the disbanded unit, doing so after it resolves a hostage standoff at the Chinese embassy. Soon she becomes a mark for Hideo Kuze of the Individual Eleven and is drawn into the ensuing investigation. With the American Empire's economy collapsing while Japan flourishes, her government negotiates a fresh security pact on terms that favor Tokyo.

During the Refugee Crisis, Takakura orders both Kayabuki and Aramaki seized and accused of treason for asking a United Nations team to confirm that Dejima held nuclear arms. Once Section 9 wrecks Kazundo Gouda's scheme to level Dejima, she reclaims her authority; Takakura is jailed and Gouda is slain while trying to defect to the Americans. She still governs in 2034 during the events of S.A.C. Solid State Society, having boosted Section 9's budget after Motoko Kusanagi's departure, though the unit is later dissolved a second time for reasons never explained. Re-elected repeatedly, she stays in office until 2045, when Chris Otomo Tate takes over as prime minister.
