Spoiler:- Jiraiya, Pein:
oh yeah, forgot to ask this (kind disturbing in a way, but I need to ask this )
do you think that Naruto and Karin are brother and sister ?
Since Naruto looks like his dad, Yondaime, couldn't his eventual sister look like his mom ? red hair ? Tomboyish attitude, and time will tell if she'll be a beautiful woman like her possible mother, but still this is one theory I'd love to see
