Platinum Dice is a Shadow that appears in the 7th through 9th Chapters of the Void Quest after being summoned by a Leading Idol. They will use Last Resort if they are left critically damaged during their turn, after which the Leading Idol will summon another to take its place. Upon being defeated, it may drop the Light String material. Selling 4 Light Strings at Daidara will unlock the Breeze Tutu female armor in the shop.
In Golden, it may only appear when summoned by Supreme Hand and Leading Idol. It may also drop Bloodstone for trade at Shiroku Pub.
