Mikami is a young man with shoulder-length black hair, who wears glasses. His typical attire consists of a black trench coat over a business suit. He can be perceived as quite attractive, but his personality takes away from his looks. Mikami has a strong sense of justice that has developed over the course of his childhood. He detests crime and expresses a fervent passion for punishing evil. His sense of justice, however, has developed into a rather "black and white" understanding of people.
