A long forgotten family member awakening in Ranma. A long forgotten war starting soon.
Ranma fights with his father at Jusenkyo, but when Genma sends Ranma into the Nyannichuan, he is disgusted at the result. Ranma didn't just get the girl curse though, he got something more. The spirit of his remote ancestress, Ra Koh, a sorceress of the Amazon tribe. And she's NOT happy at Genma for abusing Ranma. Ranma is changed by the presence of Ra Koh, some of her traits entering is personality. To the good, as much of Ranma's old ill-socialisation is ameliorated, to the extent that he successfully converts Ryoga from an enemy into an ally. And all allies are going to be needed as some mysterious monks herald a battle that Ranma will be pivotal in.
