Ranma sure did bitch a lot for someone who fell into literally the best possible Juusenkyo spring.
He's still a human being. Still has human rights, still can use his martial arts after a much briefer retraining period, can easily just change high schools and be perfectly fine.
At least you're not a duck, dude.
Spent so much of that show when I was kid like "What is this guy's problem when he gets to be a pretty girl?! You don't WANT to be a pretty girl?! Doesn't EVERYONE wanna be a pretty girl? Oh... No, huh...? That's just me? Well certainly that doesn't mean anything..."
I was kinda the same way. Free transition, I just have to watch out for extremely hot water? That is so much easier than constantly worrying about a bulge showing and being unable to wear skirts ...
