Ginga: The Last WarsEdit
Zion is inside an abandoned wooden hut, when Ogasawara Gennai and his comrades barge in. Zion introduces himself and explains that he got his name from human children. The following morning, Zion and Gennai travel down the mountain until they come across a river with a wooden bridge.
Gennai notices something in the water and upon inspection, it turns out to be a dead boar caught on the posts of the bridge. The dogs haul it out of the water and begin eating. Later that day, Rocket and Kyōshirō tell them about the threat of the bears and how serious it is.
When Gennai discusses it with them, Zion tells him that he is in fact the grandson of Gin's brother, and came to Ou in order to find his great uncle and discover his roots.
Zion runs off to find his family and Gennai chases after him. He finds the young dog climbing up a tall cliff side and upon arriving at the top he loses sight of him. Zion has made his way through the woods and has found the prison where the Ou dogs are being kept. A small bear is sat on top of the rocks and notices Zion approaching, instead of attacking, Zion greets the bear.
The bear attacks Zion, but he is spared from death by Gennai who attacks the bear himself, getting lightly wounded in the process. More bears arrive to help their brother but with the arrival of Kenshin, Bob, and Shirozaru, the bears flee leaving the dogs behind.
Shortly after, Rigel and Sirius arrive with Kawasemi, and the dogs become reacquainted with each other. However, the sound of howling echoes ominously throughout the forest, and the dogs flee in case the bears come back.
Zion and the group find Monsoon attacking Kenshin, and after the bear kills two of his followers and badly wounds Kenshin, Zion runs forward and speaks with the bears directly, confusing Bob and the bears themselves. Monsoon and Zion continue to protest to each other, but before the dogs can escape, Monsoon pounces for them.
Sirius tell Zion to listen to him, he say okay. Sirius has Zion tell Monsoon that he is a representative of the Ohu Army. But Monsoon has Zion ask Sirius if he has authority of a leader like Riki and Gin. Zion talks to Monsoon in Bear Language and tells Sirius what Monsoon said and if Sirius remembers about Monsoon's conditions that the dogs are his food.
Just as he was about to watch his cousin, Sirius about to be killed he was saved by Daisuke and Hidetoshi and along with the others he watches the bears flee. Then, he sees his injured comrades get taken away for treatment, Zion and Rigel are asked by Sirius to follow him so they can find Monsoon. He tries to talk with Bob and tell him that Monsoon gave the order to flee, but Bob tells him that Monsoon will come back. After hearing the story of Monsoon's hatred for the Ohu Army.
He sees his cousin Orion and the others come out of the woods, Zion watches as his cousins Orion and Sirius argue about what to do about Monsoon. Then, just as the two brothers were about to fight they were stopped by Andy.
Even though, the fight between Orion and his brother Sirius was broken up by Andy the opposing views still placed a gap between them. Then, Zion and the others saw Akame collapsed from exhaustion and heard from him that he wanted Orion to take the sickle. When Sirius tries to take it he gets pinned by Rigel and with that Orion calls it the last straw, to everyone's shock he disowns Sirius as his brother.
Still at Futago Pass, Zion continues to watch the argument between Sirius and Orion until Yamabiko broke up the fight. Then, heard the arrival of their allies and was asked by Sirius to translate that the bears had to run, but Zion says those bears are evil and they are not like the bears he knows, and if they don't deal with them now they will attack his cousins friends again.
When Sirius asks him to come up and translate Zion knew it was still dangerous but Sirius assured him it was okay, but was stopped by Orion. Zion, together with Orion and the others, watches Sirius try to talk to the bears but he looks on with horror as his cousin was about to get struck, but thanks to the hunters he was saved.
With all of Monsoon's Kin dead, but Akame has fallen and quickly revived as the rest of the dogs watch him and Izou leave. Zion leaves Sirius with to fill out the kishu's request without saying goodbye since Bob couldn't go Zion was the only one who could speak bear.
Sirius still wants to talk to Monsoon, he and Sirius are stopped by Bob the dog tells them that Monsoon isn't someone they can reason with. Using himself as an example convincing them not to go and asks why would a bear lend it's ears to a dog, the akitas just say Bob is speaking with energy now because Monsoon isn't here and would do the opposite if he were here. But he still considers them blind to the truth and Sirius considers that's the reason why Bob won't trust them. Zion listens to Sirius tell Bob that Monsoon has given up on him and that he's free to live the rest of his life in paradise as long as he doesn't cause any trouble. With that said they quickly leave but are stopped by Gennai but they quickly run past him following Monsoon's scent.
Finally, Zion is seen with Sirius entering Monsoon's territory looking for him. They find Monsoon at the top of the waterfall but when they try to talk to him. The white Akita tells Sirius that Monsoon still looks angry and throws a rock at them but Zion sees that Sirius isn't going to give up yet.
