Youma are attacking again, and the Senshi are having trouble. These youma are far more powerful than before. Ranma, Ryoga and the others from Nerima are helping, but each youma is more powerful than the last and each fight is more desperate than the one before it. Something is needed to level the battlefield, and Genma may have it. A real wish granting monkey-paw.
Using this, Ranma can become powerful enough... but at what price?
Why have four young men named Ranma and one young woman named Ranko disappeared from the face of their worlds?
And why the heck is Kami-sama laughing???
