The story begins 14 years after the events of Ginga: Nagareboshi Gin, where Gin led 750 dogs into a battle against a bear demon, Akakabuto. He became a hero by vanquishing Akakabuto using the Battouga attack, a technique of the wolf. Gajou, the stronghold Akakabuto build for himself in Futago Pass, through the Ou Mountains, became a monument of the battle and the ruling seat of Gin's new territory. After 14 years of peace, a strange, horrible monster (Kaibutsu) invaded and overtook Gajou. During the battle, Gin sent his mate, Sakura, off with one of his commanders, Smith, to keep their unborn pups safe. Six months later, a young Tora-ge (tiger-striped) Akita pup that looks just like Gin met GB, an English setter and a slave of a rogue boss dog named Nero. The pup tried to save one of GB's friends, Sasuke, from a farm's guard dog, but all three ultimately are saved by Smith, who now has lost his right foreleg. Smith recognizes the Tora-ge pup and is led to Sakura, who is deathly ill. Soon after Smith's arrival, Sakura dies. With his father missing and his mother dead, GB and Smith take the pup in; GB names the pup Weed, due to his tenacious spirit. The group has several adventures on their way back to the Ou Mountains, and find more allies as they battle and defeat Kaibutsu, who was a genetic experiment gone wrong. But Gin and his lieutenants are still missing. They are found and captured by Hougen, a rogue boss dog from the Southern Alps. Using Gin as a hostage, Hougen launches an invasion to take over Gin's territory. Weed and his followers must gather allies in order to save the dog's paradise.
