In a world where history took a different path, Japan has been isolated from the outside world by steam-powered robots that repel all invaders. Inside Japan, however, the people are divided into feuding and fighting feudal factions. Feisty Keiichiro Tokugawa dreams of changing this and unifying Japan, and he just may be the one man who can use the legendary giant robot Susanoo. Unfortunately, just touching a woman makes him break out in hives, and the Susanoo ALSO requires a female copilot. In VERY close quarters. And just to twist the katana, while there seem to be plenty of women who might covet the copilot's seat, not all of them have his best interests at heart! Who can he trust? Kiriko the Ninja? Chiharu the fox-demon? Or will Keiichiro's rash ambitions be thwarted by rashes and a totally rational phobia of the female form? It's a giant robot show like no other as the birds, the bees, and the giant robots take flight in DAI SHOGUN!
