Chaos Academy is an anime style tactical card game. One hundred billion years ago, the two forces of Order and Chaos formed in the Universe, participating in an endless cycle in which one absorbed the other, only to be reborn once more. In the end, Order and Chaos finally realized the futility of their path and agreed to work for mutual sustainable development. At the birth of the new civilization, Order and Chaos agreed that they would not enter the human world in their true form, and worked together to seal the plane where humans lived, preventing them from breaking the deal. But under the terms of the agreement, Chaos and Order could use the “Emperors” they created to influence the human world.
Emperors existed somewhere between the supernatural and human worlds, receiving eternal life. A period of harmonious coexistence between people, gods and demons was established, which lasted tens of thousands of years. This additional system formed a seemingly perfect circle. But as humans overdeveloped technology, they soon forgot about the gods above and the demons below. Without the power of faith, their strength weakened. And the emperors, they gradually lost the power bestowed upon them by Chaos and Order.
