For the poor, Edo is Hell on Earth, starving under the rule of Tanuma Okitsugi, corrupt councilor to the shogun. But the courageous vagabond called “Kageboshi” (Shadow Avenger), will fight for the common folk, robbing the rich so the people will have rice. Tanuma’s henchmen will hire an evil swordsman to pose as Kageboshi, starting a wave of murder, kidnapping and robbery, searching for two antique sword-guards that will reveal the hiding place of a fortune in buried gold. But who will claim the gold? The poor of Edo, or the conniving Tanuma? Only Kageboshi’s flashing sword, tearing through Tanuma’s bloodthirsty minions, can forestall his wicked schemes.
