Mikuru Kobayashi (小林みくる, Kobayashi Mikuru), also known as Cure Mystique (キュアミスティック, Kyua Misutikku), is the deuteragonist of Star Detective Pretty Cure. She is a clumsy yet honest second-year middle school student from 1999, who joined the Cure It Detective Agency in Makoto Mirai City with the goal of becoming a star detective. She has plenty of detective knowledge and works harder than anyone else. Rather than relying on gut instincts and intuition thinking, Mikuru prefers to think things through at length to reach answers. She loves cute things more than anything.
