I know this topic is kinda old now but watever
Just a theory,but bear with me:
So, if all of the paths of pain were meant to be people that Jiraiya met, yet the Animal path died and became a female...
All of the paths' pasts were explained
Except the female body.
Any slight way the female path of pain was Rin's body?
I figured the original path that Jiraiya knew of died, so they had to think of a different meaningful replacement..
Hmm?? think about it, please no flaming or raging
keep in mind that Obito's hair grew n looked different also
