Aurora Curtain

The TV Asahi's official episode guide for 2019：エターナル・パーティ is the primary mode of transformation and transportation used by multidimensional travelers. It originated in Kamen Rider Decade. 
==Overview==
The Aurora Curtains act as the doorway between the many A.R. Worlds, often used by Tsukasa Kadoya, Daiki Kaito, and Narutaki to traverse across the multiverse, with almost little to no restriction in terms of space. So long as a curtain was activated by a user, anyone can pass through them. For example in , Decade and sent their defeated victims through their own activated curtains. As the defeated heroes arrived in a safe diemnsional rift, the Decade and GokaiRed simply summoned another curtain to allow the heroes to return. However, for Aurora Curtains which were created by the worlds itself, it might become a barrier to prevent living objects from passing through. 
Due to overuse of the curtains during his early time as the leader of Dai-Shocker, Tsukasa suffered from amnesia, causing his powers to become unstable and start the Rider War where it began converging the many A.R. Worlds, with it being accelerated due to the existence of Decade himself. The worlds were restored after Tsukasa sacrificed himself in Kamen Rider × Kamen Rider W & Decade: Movie War 2010. Tsukasa was resurrected due to his heroic acts during his amnesiac period, allowing him to co-exist alongside the A.R. Worlds and travel between them without fear of world convergence or amnesia again. 
It can also be used to travel through time. The curtains also grant its users protection from temporal alterations in their current dimension, allowing them to act as time capsules for the multiverse, should they somehow be affected. 
The curtains were also technologically imitated through Ho-Oh Kaguya Quartz's creation of the , a giant Decadriver-shaped machine that granted its inhabitants prosperity through travel between worlds. However, if the system overheats, travellers who use this system to travel to parallel worlds will be forced to return to their homeworld, while losing the memories of the parallel world, though their related memories may get recovered under certain circumstances. The Hundred can also uses the Aurora Curtain to traverse across the multiverse, their relationship with the Aurora Curtain System is currently unknown.
