Ryo Saeba is a "sweeper" in the city of Tokyo. His works as a trouble shooter, cleaning the streets of vermin, and helping out desperate people. Sometimes he's a bodyguard, sometimes he's an assassin, whatever Ryo does he does it well. In fact his only flaw is his hormones—he loves the ladies and sometimes turns into an idiot when he's near them. Thankfully he's got people like his partner Kaori Makimura to keep him in check.
