Cast Points (often abbreviated as CP) were the currency used in Deadman Wonderland, kept in cards called Cast Cards, similar to a debit card. As the currency, CP are required for everything from food, to clothing, to Candy. Unlike debit cards, Cast Cards require only a quick scan to be read. A Cast Card belongs to the standard equipment for any prisoner in Deadman Wonderland. Cast Points cannot be used to get an early release for the prisoners in G-block.
One CP = ¥1 = $0.0127 = €0.0102
