To commemorate the 5th anniversary of Hatsune Miku's birth, this model is engraved with an original design drawn on the back of the "Walkman" S series and a serial number that proves that it is the only one in the world. In addition, we will pre-install the wallpaper of the original design and the full version of the song "Hoshi no Kakera", which is provided only in the short version on the Hatsune Miku official website.
