Plot

Kuroi Maya is a female detective who has no sense of loyalty to her organisation, completely ignores rules and loves to see troubled looks on people's faces. She became a detective so that she can torment bad people all she wants. However, she has the ability to get to criminals faster than anyone else because of her keen perceptiveness. Good-natured, earnest but careless Daikanyama Shusuke, is a police officer who works at a police box. At home, he is caught between his strong-minded mother and sister, and gets pushed around every day. But he makes the acquaintance of Maya at a crime scene. Shusuke is unlucky to find himself partnered with her to solve all sorts of cases together.
