This might be a Tomodachi Life 2DS ⊟
It’s pretty much the same “mint x white” color scheme used in the Japanese Tomodachi Collection 3DS XL, which suggests this is preeeeetty likely to be a special edition release concurrent with the game.
Looks pretty nice! Maybe consider this possibility if you’re about to buy a 2DS.
