World of Ataru

The World of Ataru (アタルの世界), also known as Real World (現実の世界) were an alternate timeline created by Super Time Jacker Tid in his quest to erase history of all Heisei Riders. As a result of his actions, Kamen Riders became fictional in this world with Shingo Hisanaga being the only one to remember then due to his nature as Singularity Point.

It was ultimately merged with the World of Kamen Rider.
