Kosaki's sister who is a school year younger. On her way to school, she is saved from some delinquents by a mysterious prince (actually Raku Ichijou) and ends up with his locket. Her first impression of Raku is negative as she observes that he is a womanizer who is trying to trick her sister and he is a pervert for looking at her panties. She also refuses to return his locket until Raku convinces her that he is helping the "prince." Unlike her sister, she is a good cook. She later reveals that she was helped by a guy in a mascot costume (also Raku) who treats her to ice cream. Later, she nurtures some feelings of love for Raku, but she later backs off, since she finds out that her sister, Kosaki, also has feelings for him. Instead, she decides to support her sister, despite her strong feelings for him.

Casino King is the name that the Gambling King gives to any area where he can set up his rigged gambling games, which include dice games, card games against the King himself, and pachinko machines. It is typically little more than a small stall at a fair or festival, or some relatively sheltered spot in an out of the way position on the street, but when the King successfully "wins" the Tendo Dojo from Ranma in a rigged game, he converts it into a much larger version, taking advantage of its wide space and sturdy roof.
Nodoka is Ranma's loving mother. She hasn't seen him and Genma in over a decade though, when they left on their training trip. Stating that a doting mother would hinder Ranma's training, Genma made a contract with her to raise Ranma as "man amongst men", and if he failed, he and Ranma were to commit seppuku. However, because Ranma's curse makes him a woman half the time, they spent most of Nodoka's appearances hiding from her as Ranko Tendo and her pet, Mr. Panda. Nodoka's heart was constantly broken by knowing that she wanted nothing more than to see her son again. Eventually in the manga, she did meet Ranma and Genma and discovers their curses. However, she was more accepting than they expected. Mostly because she eventually began to suspect that Ranma and Ranko were, in fact, the same person. (Wikipedia)
