For anyone here who's using Miitomo with a Japanese Nintendo Account linked and used their Mii from their Nintendo account, I've got a question for you... If you use your Mii from your Nintendo Account, does your Mii update in Miitomo if you change it on another device linked with that account (Nintendo 3DS or Wii U)? I'm not sure how I want to go about creating my personal Mii in Miitomo... The most ideal way would be to use my Mii's QR Code from Tomodachi Life, since that would carry over my voice and personality with it. However, if pulling your Mii from your Nintendo Account actually links it with your 3DS and/or Wii U, I'd prefer to go that route, 'cause if I make any changes to my Mii I'd like it to update across all of my devices... But I'm not sure if Miitomo even works like that. It seems the only way to change your Mii after creating it is by manually editing it. There's no option to update the Mii via QR Code or anything...
