Ms. Sadistic Detective(2015)

Ms. Sadistic Detective is a Japanese crime series following Kuroi Maya, a detective driven by sadistic impulses rather than duty. She became a cop to torment criminals, yet her sharp perceptiveness makes her exceptionally skilled at catching them—rules be damned. When earnest but hapless police officer Daikanyama Shusuke meets Maya at a crime scene, he's forced into an unlikely partnership. Shusuke, already pushed around by his domineering mother and sister at home, must now navigate cases alongside a woman who delights in psychological torment. Their clashing personalities—her ruthless pragmatism against his good-natured earnestness—drive the show's darkly comedic tension as they solve crimes together, each challenge revealing more about what drives them both.
