During the Fourth War of the Sun, a small dog named DOGGY experienced an irreparable trauma: his mother was brutally murdered, and his eight brothers, still puppies, were kidnapped by a mysterious man. To save them, Doggy fought bravely against the terrible killer, but all his efforts were in vain, and he was left for dead. What nobody imagined was that a technological vulture scavenging the region for corpses would be the one to rescue the dying dog from death''s scythe. Now, Doggy has become Samurai Doggy, and his only goal is to quench his thirst for revenge.
