Ginga Nagareboshi Gin
Ben the Great Dane is the leader of the first platoon in the Ou army. The leader greatly entrusts Ben as a soldier and friend. He goes to help gather males and has connections to the Kai brothers and Akame in the past. When the Kai brothers were puppies he saved them from a murderer and made sure they were alright. Akame was shot by Ben's master by mistake and Ben set Akame free so he could return to his pups and Iga clan in the wild. Akatora, Chutora, Kurotora, Akame and the Iga dogs join the pack due to their connection with Ben. Unfortunately when Ou soldiers first meet Akame on the Iga grounds they run onto the poison spikes in the area. Ben refused to take any medicine until the rest of his soldiers were healed. He has issues with his vision from the poison and eventually becomes blind. Without his sight he couldn't be a proficient leader so he chose Gin to take his place and become the leader of the first Platoon.
He is left behind with Moss and Cross on a ship as Gin and the others gather fighting dogs from Shikoku. It is suggested that he goes back to his master so he can have his eyes healed. The humans do some work but being impatient, knowing the fight with Akakabuto is near, Ben breaks out of his cage and run to his pack. His vision seems to be fine and he prays it lasts until the fight against Akakabuto. He meets up with part of the pack in Mutsu where the dogs are cornered by the four Husky Generals of Mutsu (Kisaragi, Minazuki, Uzuki and Hazuki). The dogs battle and the Ou pack's bravery inspires the Mutsu pack to join. They only fought dogs while the brave, real males of Ou were going to take on a demonic bear!
Cross is his mate and she becomes pregnant with his puppies. The day before the battle with Akakabuto she gives birth to three puppies and Riki asks Ben as a friend to stay behind with Cross so Nem can enjoy his children and be a good father. Ben does not obey however and Cross understands. Sniper encounters Ben and they fight. He drags Sniper down a cliff to kill that traitor. Hyena nearby is inspired by Ben and so he gains bravery and jumps down the cliff into his death. Luckily Ben survives and later is able to fight against Akakabuto. Ben is the first dog to sink his fangs into that evil bear. With his strength and determination he throws Akakabuto down from his rock castle for the rest of the pack to attack him.
