Saeko is the eldest of the Nogami sisters and a beautiful woman detective of the Tokyo police. She is able to shoot the bull's eye out of the target board with her S&W 38 special, however, prefers the 16 throwing knifes she carries on her stocking as her weapons (but how can she manage in preventing herself from being hurt?!). Saeko on the screen drives a red Porsche 930 turbo. There are a lot of leeways she has in doing police works, since her father is the chief of police of Tokyo city. (who is consistently introduces her to new male partner in hope of a marriage. Saeko, in turn, sends all of them to the hospital after those men fail her "test"! She does not want to marry to a guy who is weaker than she is :)
On many occasions Saeko will come to Ryo for aids, while promises to go to bed "one time" (ippatsu) with Ryo after the thing is done. But she always manages to wriggle out of it at the end. That is why Ryo keeps a running track of how many "times" Saeko owes him. She is one woman who knows how to use men with her beauty to achieve her end.
However, there is more to Saeko and Ryo than meet the eyes. There was a time when both Ryo and HediYuki, the former partner of Saeko, were in love with her, and Saeko also loved both of them. She was going to make a decision between them when HediYuki was killed. Afterward Saeko could not even think about it for a long time. While Ryo, thinking about HediYuki and with the addition of Kaori, sort of back off from the relationship. Still, their feelings toward each other are deeper than appearances.
