Koringo is the son of the talking cat Mikan in the anime Mikan Enikki. He appears later in the series, following Mikan’s starting a family. In the anime adaptation, Koringo never develops full human speech; his vocal ability is restricted to mimicking a few random words, particularly those related to food, and he remains that way throughout the series. His role is that of a family member within the Kusanagi household, and his interactions are primarily with his father and the human family. As a young cat with orange fur, he closely resembles Mikan. Koringo’s limited speech serves as a notable trait that distinguishes him from his father and emphasizes the unique nature of their lineage. He contributes to the domestic and comedic dynamics of the story.
