The Kenshin-gumi's brief period of peace is interrupted by the presence of former Shinsengumi captain Saito Hajime - now using the name of Fujita Goro and working for the Tokyo police - stirs up some of Kenshin's bloodiest memories of the Bakumatsu. Saito arrives at the Kamiya dojo disguised as a medicine seller and fights Sanosuke, injuring him severely in the process.
