At a young age Genma takes Ranma to China where he is cursed and then subjects him to the Nekoken. Cologne finds Ranma and rescues him. When they try to heal him, the curse acts and gets rid of the Nekoken at the cost of Ranma’s maleness. Nodoka is contacted and picks up her daughter, training her in the sword forms of her family. Years later Ranko arrives at the Hinata Sou to stay. (Love Hina Crossover.)
