Silver Fang - Akame. 2

Akame, a Kishū Inu. He is the leader of the Iga Ninja Dogs. Ben first met Akame when he was still a hunting dog, his owner believed that Akame was a flying squirrel and shot him, wounding his leg. When he realized his mistake, the human brought Akame to his home and treated his injuries. After his wounds heal, Akame pleaded to Ben to let him out of his cage, as his pups were still too young to survive on their own. Ben relents, and Akame returned to the forest to lead the Ninja dogs.
Years later, after falling for Kurojaki's scheme, Akame poisons Ben and his group. Later realizing Kurojaki's treachery, Akame is devastated and, with Gin's help, brings Ben and his dogs the medicinal herbs that will cure the poison. Though they save the packs lives, Ben is left with permanently impaired vision. After a battle against Kurojaki and the other Kogas, ending in Kurojaki's suicide, Akame joins Ben in his mission and they leave for Shikoku. In the manga, he later becomes the Shuu Tossou Battouga (襲突槍抜刀牙?) Hakkenshi warrior. Voiced by Michihiro Ikemizu.
