Saeba, Ryou

The protagonist of City Hunter. Ryou is a combat expert, having fought as a guerrilla in numerous conflicts alluded to throughout the series, and has a long history of working in the underground. He carries a Colt Python. His mysterious past starts with him being the only survivor of a plane crash in Central America as a toddler. The crash left him an orphan in a rebel village during a civil war, prompting him to learn to fight at a young age. As a result, he has very little information on his true parentage, or even his birthdate. (Later, Kaori Makimura unilaterally declared March 26 his birthday, as that was the day they first met). After the war he ended up in the United States, where he worked as a hired gun, but eventually he found his way to Tokyo, Japan. There he formed the "City Hunter" team with Hideyuki Makimura (Kaori's brother), and it's sometime after that where the manga/TV series' timeline begins.

One of Ryou's most striking traits as a character is his extreme sexual excitability. Especially in the manga, where, as Saeba himself often notes, he experiences an erection every time he sees or even thinks about something sexual. As a result of this, he constantly flirts with, tries to seduce, or even literally harasses most of the female characters he finds sexy. Even with those whom he knows and respects well, to the point of refusing to take orders from men unless their request touches something in his soul. And while he can always pull himself together and take things seriously when needed, various adaptations often downplay this trait of his to still exaggerated, but more tame dimensions.
