How do you get premium gacha tickets?

[Miomiomi]

Im a new player, and the new gacha just came out, with all the "fan favorited" stuff (i guess)
I dont know if this is the proper place to put this but im really curious
I dont wanna spend my real money on anything so i hope its something in-game

It seems you cant use OC to roll in it, and i really want one of the outfits.

The only way to get them is to buy OC, you get 1 for buying a total of 3000 oc during the campaign and 2 for buying 5000 oc
