Furyu released today the new Osomatsu-san Nintendo 3DS themes in the Japan eShop but these themes are very special ones. As you can see they are collaboration ones with the Hello Kitty, Tuxedosam and KeroKeroppi.
You can buy them one by one for 200 Yen (with tax) / theme price from the eShop (you can’t buy them in package). In the gallery you can find the sample pictures
