World of Blade

The World of Blade (ブレイドの世界) is the version of reality where Kamen Rider Blade takes place. In this world, the Riders are high rank employees of the BOARD Corporation (株式会社BOARD), and are effectively "Kamen Rider Salarymen" (仮面ライダーサラリーマン), whose job it is to combat the Undead once receiving clearance to use Rouzers. In BOARD, there is a ranking system with Ace (エース) at the top followed by King, Queen, Jack, and the numbers with Two at the bottom. The backdrop used to arrive in this world shows a hand of facedown Rouse cards with the Ace of Spades (Blade's Change Beetle) face up. Within this A.R. World, Tsukasa assumes the role of chief waiter within BOARD and is given the ability to completely destroy Undead without sealing them.
