ARC Area Project

ARC Area Project is the name of the project devised by the Professor, Leo Akaba, and as such the goal of Academia, which involves the use of the power of Fusion to make all the worlds become one and creating utopia that supposedly will bring peace. However, Asuka revealed that this is actually a cover up for the Professor's plan to conquer all four dimensions. While the exact method of uniting the four dimensions into one is yet to be revealed, the project requires Yuzu and her dimensional counterparts, and involves invading the other remaining dimensions and turns every single of its residence into cards. All of the carded people are then collected and later seems to be gathered inside a huge device inside the Academia castle that is located behind the Professor's throne room. It's late revealed by Leo that ARC Area Project is simply a solution to enact his own personal plan, Revival Zero, which is to fuse Yuzu and her counterparts' bodies to revive his daughter, Ray.
