|This article is about a/an organization in Kamen Rider Decade.|
BOARD Corporation (株式会社BOARD Kabushikigaisha Bōdo) is the version of BOARD that exists in the alternate reality World of Blade. In this world, the Riders are high rank employees of the BOARD Corporation, and are effectively "Kamen Rider Salarymen" (仮面ライダーサラリーマン Kamen Raidā Sararīman), whose job it is to combat the Undead once receiving clearance to use Rouzers. In BOARD, there is a ranking system with Ace 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 Change Beetle card faced 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.
