I hope Kishi shows more insight on Naruto's mother, It's been left as a cliffhanger for too long now in the manga. (I still hope for Mizukage=Kushina
) but it could be anyone's guess at this point.
You still hope for Mizukage = Kushina? Seriously? Well the chances of that are less than 1% but we all live in hope I guess. The chances of her being related to Kushina somehow is more likely than that. Afterall We have no idea what happened to all the refugee's from Whirlpool, they could be scattered all over the place. We still don't know if Kishi did this for a reason other than her not being well known if she belonged to another village originally, keeping Naruto's past in the shadow.
It's one of my pet peeves, where the mothers past is never given the proper time and effort as the fathers, He only looks like his father but his personality and style of fighting is all his mother, so why not give us more insight on the parent he got his spirit from. (Had the same problem with Harry Potter, He only looked like his father everything else was his mother yet it was alway how he looked like his father.)
She sounds like a fierce passionate person (from the two sentences we got about her) She probably didn't take crap from anyone, and was not blown over by Minato's looks. So hopefully we'll learn more about her soon and also about Whirlpool, maybe the Mizukage' is a long lost Aunt or something, could be we haven't even been told her name so anything is possible.
