Deka is a character from the 1970s anime adaptation of Norakuro, appearing as a member of the Fierce Dog Regiment, also known as the Mokenrentai. The character is a male dog who holds the rank of Private within this military unit. He is depicted as one of the canine companions who train alongside the protagonist, Norakuro.

Deka is consistently listed as a main cast member for the 1970 television series, appearing in all 26 episodes. In the context of the story, which focuses on the daily training and problem-solving within the Fierce Dog Regiment, Deka serves as a fellow soldier and comrade. His role is to be part of the ensemble of regiment members, which includes other officers such as Regiment Leader Bull and Squadron Leader Mole.

Regarding his background and personality, the available information does not provide specific details. There are no confirmed records outlining his personal history, motivations, or individual character development over the course of the series. Similarly, while he is identified as a companion to the other soldiers, no specific key relationships or notable abilities are documented in the search results. A modern reimagining of the franchise, Norakuro-kun, shifts the setting away from the military to depict a peaceful coexistence of humans and dogs, but details about Deka's specific role in this version remain unclear.
