Time to give that good ol' QR code reader on your 3DS/2DS some work.
Just set your sights on the lovely QR code image bellow and you too will have a Mii Conchit in your roster.
This should ensure some hilarious shenanigans in Tomodachi Life when it's finally released in the west.
UPDATE: Did I with a single QR code image just tear down the whole thing about same sex couples in Tomodachi Life!? Nintendo, I'm available for future consulting. I'm also quite cheap.
MORE UPDATE: Added picture of how Conchita looks like in Tomodachi Life.
