Norakuro, a black dog, serves as a private second-class in the "Mokenrentai" (Fierce Dog Brigade), an imperial canine army fighting a war against the enemy Monkey Army. He is a stray black-and-white dog among an army of white dogs, constantly blundering his way through his duties. This series largely stuck to the source comics, though one major departure was the addition of army nurse Miko, whom Norakuro develops a crush on. In this adaptation, Norakuro is voiced by Nobuyo Ooyama, who later gained fame for voicing Doraemon.
