A man called "the King of Death" moves through 1930s Shanghai, a city divided among foreign powers and Chinese factions, each governing separate districts with corrupt rule. Gangs dominate the streets amid political struggle and lawlessness. Once, a warrior known as Yan Wang fought the city's criminals using the deadly martial art Hokuto Shinken. After eliminating the worst gangsters, he vanished and is now said to be in Japan. Several individuals have traveled to Japan seeking him, but it remains unknown who will locate him first.
