==Background==
Tsukasa Kadoya and Sayo Kadoya were born in this world, where they had a butler named Nobuhiko Tsukikage. 
The evil organization Dai-Shocker had also originated from and were based in this world. After Tsukasa developed the ability to use Aurora Curtains, he was recruited to be their leader and help them subjugate the various A.R. Worlds. Daiki Kaito had also arrived in this world and stole the Diendriver from Dai-Shocker, who had also created the Decadriver for Tsukasa's use.
After his amnesia, Tsukasa returned to this world where he learned of his past.
