Norakuro is a black dog serving in the "Mokenrentai" (Fierce Dog Brigade), an Imperial army of dogs engaged in a war against the enemy Monkey Army. Norakuro is a stray black-and-white dog within an army of white dogs, having blundered his way while holding the rank of Private Second-Class. This series was relatively faithful to the comics. One major change, however, was the addition of the army nurse Miko, whom Norakuro had a crush on. For this series, Norakuro was voiced by Nobuyo Ooyama, who would later become noted for voicing Doraemon.
