You know that whole Weakness Moxibustion thing? What happens when it begins to spin out?
A common divergence point - the Ultimate Weakness Moxibustion is on Ranma, and Happosai holds the only remaining hint of a cure. Only, this time, the divergence isn’t quite in the same moment as in other alternate universes, and Ranma’s life takes a radically strange turn because of a single, simple decision...
Happosai made a mistake while Ranma was weak. In order to make sure that Ranma would not be able to get the chart, he ate it! Now there's no way for Ranma to regain his strength. A depressed and currently female Ranma goes for a walk to think about things. Possibly not a wise thing to do when you have no way to defend yourself...
