Kosuke Inaba is a supporting character in the anime Miami Guns. He works as a police officer for the Miami City Police Department and is a member of a trio of particularly incompetent investigators who receive training from the main protagonists, Yao Sakurakouji and Lu Amano. Kosuke has a notable talent as a photographer, often claiming that he never misses a snapshot. This skill complements his personality, as he is depicted as a peeping tom, which reveals a voyeuristic side. He has red hair and black eyes. In the story, Kosuke functions primarily as comic relief, with his lack of competence and questionable habits adding humor. His key relationships are with Yao and Lu, who attempt to turn him and his teammates into capable officers. He does not undergo significant character development and remains a static figure throughout the series. His most prominent ability is his photography, though his overall performance as a detective is marked by ineptitude.
