What if the people of Japan never had to unify because mystical steam-powered robots defended the island from outside attack instead? That's the history Keiichiro Tokugawa grew up in, but the brash teen has the reckless ambition of helping unite the feuding feudal factions... and with some headstrong heroics and the help of the legendary giant robot Susanoo, he just might be able to do it! However, he'll have to deal with his girl problems first: the Susanoo requires a co-pilot-a female co-pilot-but every time Keiichiro gets close to a member of the opposite sex, he breaks out in a rash! Can Keiichiro find a nice young lady he's compatible with? Or will his feminine issues thrash, crash and forever trash his hopes of ending the futile feudal feuding forever? The answers await in DAI SHOGUN!
