At the end of the Edo Period, there was a legendary chivalrous thief who stole from rich merchants and self-serving samurai and gave to the virtuous people of the town. His name was Nezumi-kozo (Rat Boy) Jirokichi. This musical is about how he competed with and was friends with the hero of so many period dramas (Touyama Kinshiro), and about the loves they surrounded themselves with in the new and progressive Japan. A Takarazuka take on the tale of Nezumi-kozo.
