Ok, I have some OCs that will show up some in this fic. Here's a list of the ones you've been introduced so far.
Original Characters...
Suko-baachan
Suko is the old medince/herb lady that Naruto befriended as a child. She was one of very few (if at all any) villagers that saw past the Kyuubi to the little lost boy. She fixed him up after several bad incidents from the villagers and she stands by the fact that not even Kyuubi could heal Naruto intergestion without help after all the ramen the boy consumes.
She also helps out with Naruto's pranks, often suppling him with the material he needs – especially with the legendary pranks of Naru VS Tora.
Suko, while old, is has an endearing child-like quality around her when she's with Naruto. She feels and acts a lot younger when she is with the child, and has kept up good relations with Naruto even as he grew up. She was the one to help Naruto find an apartment after Naruto moved out of Iruka's home and she babysitted a lot for Iruka before he got the teaching position.
Suko is a lot older than she appears and knows more than she lets on.
She will play a small role while Naruto is a child.
Mrs. Tanaka
Mrs. Tanaka is an old retired medic-nin (though she normally volunteers to help out at the hospital with training new medic nins) whos house was the Rank D cleaning mission.
Naruto stumbles upon the Child-no-Jutsu in her basement that he was allocated to clean and comes up with the idea to use it on Sasuke.
The jutsu is normally used with training medic-nins in childcare. It's used with partners; to turn one into a child (so they see things from a child's perspective as they remember everything when changed back) while the other looks after the child (learning the basics in child welfare and raising).
Naruto hid the scroll he discovered the justu in, and as Mrs. Tanaka was absent – Team 7 had no idea what went wrong or how to reverse the jutsu. Mrs. Tanaka won't show up again for a bit, unless it's really minor.
Don't know what has happened to Mr. Tanaka (there needs to be one if she's Mrs.) but he is unimportant at the moment and most likely never to come out in this fanfiction. Mrs. Tanaka actually shows up in a few of my fanfictions and stories (not that I think I've posted any with her in yet) and she's really tied into the doctor role - often in my baby!fic ideas.
Well that's all for now. I'm off to have some dinner. I've been in a bit of a reading rather than writing mode; especially with the Harry Potter fanfiction. I'll try to snap out enough to finish the next chapter and update soon.
Thanks for all the reviews.
