Manga Plot:
The story of Ginga Densetsu Weed began in the Northern Alps of China. There, a female Kishu mix named Sakura gave birth to three puppies – Joe, Yukimura and Weed. However, Sakura got very ill and asked a dog called Sakachi to take care of Joe and Yukimura, since she was too weak to gather food for them. Weed was then left alone with his mother, and provided for her for as long as possible. He met an English Setter called GB in the mountains while hunting. Weed then returned to his mother and got attacked by crows. GB chased them away, and talks to Sakura. She asks GB to take her son to Ohu to meet his father, Gin – the Great Leader of Ohu.

The journey starts, and the first challenge Weed has to face is the fight against the evil brothers Bell, Ned and Blue. Together with his friends, Weed overpowers Bell and Ned while Blue escapes over a fence. He gets killed when he walks in front of a large truck. Weed then continues his journey towards Ohu to find his father. But he finds that the “Utopia” of Ohu is gone, and that the mountains are being terrorised by the mutant dog, Kaibutsu. Weed joins forces with Kagetora, Ken, and Jerome and his soldiers, and together they kill Kaibutsu.

Meanwhile, Gin, John and Akame have been surrounded by the evil dog Hougen, who wants to overthrow Gin and rule Ohu Mountains. Gin and his friends fight bravely, and a Molosser by the name Hiro joins the fight. Gin commands Akame to escape and get help, while he, John, and Hiro are taken as hostages by Hougen. Akame escapes quickly and finds Weed in the mountains. He tells him what happened, and Weed starts a journey with a Borzoi named Rocket to the Chinese Alps to find more dogs to help him defeat Hougen. Soon, Weed finds out how powerful Hougen is. Hougen sends assassins to kill Weed, but Weed overpowers them both with the help of the Kishu-Inu called Kyoushiro Shirogane, who joins forces with Weed. They are also joined by the German Shepard, Tesshin, who teaches Weed the Zetsu Tenrou Battouga (the death strike.) While Weed is searching for comrades, Akame gathers the old soldiers of Ohu - Ben, Cross, Kurotora, Moss and Mushashi. They combine forces and help Weed when he gets surrounded by one of Hougen’s minions, Kamakiri. Now, Weed and his group start planning their attack. First, they take out Hougen’s brother Genba, and then Kamakiri. When the final battle against Hougen comes, Weed is finally reunited with his father. However, Gin refuses to help Weed. This is a task Weed has to complete himself. Weed fights bravely, but is almost killed. As Hougen moves in to kill Weed, a howl is heard through the Futago pass. Shadows begin to emerge and the spirits of the dead soldiers of Ou come to give Weed strength to stand up and defeat Hougen. He uses the Zetsu Tenrou bBattouga on Hougen, who falls bloodily to the ground. He is finally killed by Shouji Sudou, an old police officer who shoots Hougen several times in the head.

Now, peace is restored to Ou for a short while. One of Weed’s group members, Jerome, runs to the South of China because he doesn’t feel like a part of Weed’s pack. When Weed follows, he meets his brother Yukimura. Here, Weed finds out that his brother Joe has been killed by a pack of monkeys who terrorize the area. Weed now joins forces with the leader of a rebellion group called “Gosaru,” and together they defeat the leader of the monkeys, Shougun. Unfortunately, Weed loses his brother, who is killed in the fight. Weed says farewell to the Gosaru and continues his adventures.

Soon, Weed meets a female Kishu Inu called Koyuki. Weed falls in love with her, but unfortunately she is a pet dog who doesn’t want to leave her owner. When Weed saves Kotetsu, Koyuki's younger brother, Koyuki falls in love with Weed. However, she has to say goodbye to him, and leaves him. Meanwhile, Jerome has travelled to Hokkaido, where he is attacked by the German shepherd, Victor. He is badly wounded, but Ridia, one of Victor's minions, accidentally lets him escape. Jerome is found by Hakuro's sons and brought to safety on a farm in care of a collie, Ramu. While Jerome rests here, Hakuro enters a fight with Victor's group who has gotten reinfocements. Hakuro loses and must retreat. But by the blood he has spilled, he swears to finish off Victor's terrorizing once and for all and prepares a final attack. Meanwhile, Koyuki's brother Kotetsu runs to tell Weed that Koyuki is leaving. Her human has put her in a cage and sends her away. As Weed hears this, he forgets everything and follows the car. He jump onto the load of it and stays with Koyuki, leaving everything he has ever known behind him.

Hakuro gets ambushed by Victor for the final battle, but instead of winning, Hakuro gets killed during the fight. Jerome appears shortly after, searching for Hakuro and he finds himself in the middle of the war-zone. Victor sets Ridia and Maxime to watch over Jerome so that he doesn't escape, but instead of being cruel and rude, Ridia starts to have certain feelings for Jerome. Maxime don't want to make his sister sad, so he aids Jerome too. Meanwhile, Hakuro's son Susaku has rushed to Ou to tell Gin of what has happened. Immediately, Gin follows him to fight Victor. At the same time, he sends out Ramu to find Weed and inform him of the situation. Gin then presses forward and fights Victor. However, he has to retreat when Victor's reinforcements arrive. Akame is now send out and saves Jerome. Ridia is taken along too and later on Maxime too joins the Ou army. However, as Maxime goes back to try and talk Alam (one of Victor's platoon leaders) into joining the Ou fighters, Maxime gets punished by Victor and nearly killed. Victor then manages to trap Gin and his fighters in a big gorge where he keeps them hostage, hoping that they will surrender to him.

Weed and Koyuki are in the Northern Alps during this. They visit Sakura's grave and pay respect to her. Afterwards, they just fool around as the newly lovers they are. However, their little vacation is interrupted by Rocket, who tells Weed of what's happening in Hokkaido. Weed doesn't leave Koyuki until her brother Kotetsu and GB arrive. He leaves Koyuki in care of Kotetsu and then starts the journey towards Hokkaido together with GB. Weed now starts a journey to find fighters to help him defeat Victor and aid his father, Gin. He manages to gather around 1000 dogs, before he decides to travel to Hokkaido to finish Victor's terror once and for all.

Victor is defeated. Weed and his pack travel south along with Koyuki and Kotetsu. There, Weed meets a dog that looks remarkably like him, the dog happens to be Weed's brother. Joe, has a son and fights with Weed often because he is very angry with Gin for leaving Sakura unattended in the Alps, unknown to the fact that Gin was unaware why Sakura left. Joe also gets attacked by a large bear and gets 3 scars, similar to Gin's, on his forehead. When Weed asks why Joe hates the bear so much, Joe says that the bear, called Hybrid (a hybrid between a grizzly and supposedly a polar bear) killed his mate, Hitomi. Every dog trys his best to kill the numerous Hybrids. GB, Weed's godfather, works up his courage and manages to wound and cut off the finger of one of the bears, but the bear claws GB in the back two times and GB dies saving Weed who is about to get crushed by the bear's claws, saying, " I'm scared. I'm going to die, but at least this way I died saving you." Weed's pupils get remarkably small as GB breathes his last, and screams he will avenge his god-father.
