Akira is a soldier belonging to Saheiji's pack.
Akira is loyal to Yukimura so he obviously has some reason for hating and wanting to kill monkeys but that reason is unknown because it is never mentioned in the manga.

During the battle, Akira was one of the unlucky dogs as his paw was chopped off by the rampaging Shōgun before dying instantly.
- It is unknown if Akira is a younger pack member that joined under the rule of Yukimura or an older pack member that has belonged to the pack since Saheiji's rule.
