It is never said how she died, but the family still thinks of her lovingly. After Mrs. Tendo's death Kasumi assumed a more motherly role and helped with household duties. (Source: Rumic World)
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.
She was left for dead after the brutal murder of all members of her family, Henrietta is the newest addition to the Agency. She was assaulted repeatedly next to the dead bodies all night, which had inflicted psychological trauma to her, making her suicidal. Her struggle is the most developed of all the girls as she adjusts to her new life. Henrietta's favorite activity is to spend time with her handler, Jose`. Whenever Jose seems to turn his attention to other women (including the other cyborgs of the SWA), Henrietta becomes slightly jealous. This is due to Henrietta's strong romantic feelings for him, as a result of her faint conditioning and the care he gives her.
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)
