Arc System Works has new content for the free NAX Music Player. You can get Street Fighter X Tekken guests and Everyday Together hosts Toro and Kuro for it.
Toro and Kuro can dance to whatever songs you have on your Vita, but first you have to get one of these NAX Music Player DLC packs.
The Toro one includes Toro, two Toro skins, and a song from Everyday Together. The Kuro pack has Kuro, two Kuro skins, and a song from Everyday Together too. Each one costs 500 yen ($6.28). A DSP Effector pack is also available for 200 yen ($2.50).
