Yakuza Kenzan! (Ryu ga Gotoku Kenzan!) is a PlayStation 3 spin-off that takes SEGA's action-adventure franchise 400 years back in time, to the Edo period in 1605. Gone are the neon signs of Tokyo and Osaka, now replaced by the neon signs of an Edo Period Kyoto, in a story that both echoes and sets up the types of events seen in the ensuing franchise episodes. The main character, Kazumanosuke Kiryu, is a bodyguard who will take on any job if the price is right. He is approached by a young girl named Haruka, who asks him to kill a man... but this man, Musashi Miyamoto, is someone who Kiryu cannot kill, for this is the name he formerly used before adopting an alter-ego in an attempt to erase his past.
