桐生一馬
Unlike "Ryū ga Gotoku Kenzan!" (the previous game in the series, released only in Japan), which was a Miyamoto Musashi-based spinoff set in Edo-era Kyoto, this installment continues the adventures of Kazuma Kiryu from "Yakuza" and "Yakuza 2". The game takes place both in Kamurocho, a fictional version of Tokyo's red-light district Kabukicho, from the first two games, and in a brand new location called Ryukyu.
