CARDS

The Cards used in the series, are representing "Undead", a fictional race of monsters in the 2004 Japanese Kamen Rider Series Kamen Rider Blade. The story of the Undead is the focus of the series as they were created 10,000 years ago by God in the form of the a stone slab called the Monolith, to kill each other in a free-for-all battle royale known as the Battle Fight, with the winner granted a wish to alter the world.
The 52 Undead represented 52 different species and battled so they can wish for the species they represent to rule the Earth, while the Joker represented death. While the other Undead were sealed by the Monolith, the winner of that battle was the Human Undead and the world has been populated by humans ever since.
