So the hellish NY gacha present.
Combine price is 18k DMMpt, you can buy all deal I think for once / deal.
You can get 2 guarantee rainbow from this, one from 10k pt deal, another from buy all deal to get 300 rainbow coin.
It's also you can get one more rainbow from the 5k pt deal but not guarantee.
