Tokage (lizard) is an ex-cop from the Metropolitan Police Department's 1st Crime Division who couldn't work well with people, and never opened up to anybody. But he had extraordinary abilities that included a photographic memory and unmatched physical skills enabling him to crack the most difficult cases. For this, he had the respect of his peers and bosses. Until one case that led to a fatal miss: the death of his only partner. Taking responsibility for the tragedy, Tokage quit the force and began working for a private investigator's office as a researcher. But the Metropolitan Police are eager to recruit him back in an effort to raise their arrest rate, and manage to convince him to return as an undercover cop. Assigned to assist him is a young woman from the detective agency who joined for certain unavoidable reasons. But she's not in the least meticulous and smacks of a rich girl upbringing, and yet is obstinately strong-willed and doesn't back down. Together, they form an odd pair - the eccentric big name cop and the tough but cute assistant in an absolutely new kind of detective story.

High school student Sae Hirasawa lives a simple life with her mother in a peaceful northern fishing town but dreams of a life overseas. She has grown up in the shade of a dogwood tree planted for her as a young child by her itinerant and chronically-ill father, who knew he’d never see his daughter to adulthood. Sae is determined to make it into a top university and increase her chances of landing a job overseas when she meets Kohei Kinouchi, a boy from another high school. The two fall in love and together encourage each other to pursue their dreams, even as it pulls them apart: Sae to a prestigious university in Tokyo and Kohei to the open seas as a fisherman. Inevitably, the physical separation and the widening gap between their ambitions begin to strain their long-distance relationship. As Kohei misses, and increasingly regrets, not seeing Sae grow into a beautiful woman, Sae finds herself inching ever closer to her goal when she meets Kitami, an upperclassman who shares her same dream.
