In the end, he was murdered by the Giraffa Undead after he was defeated by the Riders with his dreams shattered.

In an alternate reality, Kamen Rider Blade: Missing Ace, both Tachibana and Karasuma decides to keep all of the Rouse Cards away, when the Albino Joker attacked and killed Karasuma, then unsealed the Undead. Ever since the threat, he took over the organization and becomes the chairman while he hires Junichi Shimura, along with Natsumi Miwa and Shin Magaki as the new members to reseal the Undeads as he can't rehire Kazuma and Mutsuki due to the fact that some of the unsealed Undeads are Category Ace of Spades and Category Ace of Clubs.

He is also aware of the side effect of Kenzaki's King Form as well as Tennoji's plans of the fake Battle Fight. In an alternate timeline, he and Tachibana tried to hide the 52 Rouse Cards, when the Albino Joker appeared and attacked and killed Karasuma, then unsealed the Undead.

World of Blade

In the alternate reality World of Blade, the Riders are high rank employees of the BOARD Corporation (株式会社BOARD Kabushikigaisha Bōdo), 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 then 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.
