Suikoden Demon Century

In the 21st century, an earthquake devastated Japan, destroying Tokyo and leaving its people homeless and lawless. In the present, the ruins of Tokyo are a haven for thugs and street gangs, the most powerful of which is the ruthless Koryukai gang. Takateru Suga is visiting Tokyo on a mission: to find his sister Kiyomi, but things heat up once he discovers she's been kidnapped by the Koryukai themselves! With the help of a transvestite, colonel-turned-monk and a lot of firepower, Takateru must help defeat the Koryukai and save the city, or lose everything he holds dear!
