Ranma has to regain his strength

[toushin]

This is something that just popped in my head. All I can remember is that Ranma ends up in a universe where he's a bullied wimp his cured but his cursed form is now akane's cousin who is one of his more vicious bullies. i think it is a sailor moon crossover. before ranma went off to trained he introduced himself as heir to the saotome school of anything goes. when told there was no such thing he used the anything goes ultimate secret technique. akane was pissed that ranma insulted her style by creating something like that
