ARC-V

ARC-V (アークファイブ, Āku Faibu) is the fifth world that Leo Akaba intends to create. Leo's plan, Revival Zero, is to revive his daughter, Ray. As a necessary process to revive his daughter, Leo must recreate the Original Dimension by using the device behind his throne room where all people who are carded are collected once enough cards were gathered, Leo will consolidate their life energies and activated to unite the four worlds. This new United World is named ARC-V. During the battle against Zarc, ARC-V is successfully created, merging all four dimensions. However, ARC-V is then once again split into four dimensions when Ray and Reira Akaba used the four En Cards to defeat Zarc. Although, the remains of ARC-V are still present in the form of dimension portals that allows people to go through different dimensions at will without the use of Dimension Traveling Technology. After Yūya Sakaki pacified Zarc's soul with his Entertainment Dueling, which in turn also awakened Ray's soul who was in a catatonic state within the core of ARC-V Reactor and she used the remaining power to merge the four dimensions into one again, hence, recreating ARC-V for good.
