I bought a disc with an add-on, but momoshiki and kinshiki do not. (Naruto Shippuden: Ultimate Ninja Storm 4)

Also, I don't have all the boruto costumes.

Kinshiki and Momoshiki have recently been added to the game. And they can only be purchased from the Steam Digital Store, PlayStation Store, Xbox Games Store. And discs with a pre-installed add-on for Momoshiki and Kinshiki are unlikely to be made.
