So I have had my 3DS for about three years now as well as a Nintendo Network ID. My little brother was recently given a Wii U and being the kind older sister I am, set it up for him on my Nintendo ID.
Well, about a week later, my Mii on my 3DS changed to the one he has on the Wii U instead of my own and I can't seem to change this. My personal settings are still the same, yet my name and character has changed.
Any help is much appreciated, thank you.
