Survive. That is the only way.
About
You are the chosen 8th Survivor, gaining power through a contract with an animal avatar. The cards you can use depend on your Contract Beast and include abilities, ultimate moves, and summons. However, you must fight in the Mirror World, a dimension inverted from reality. In the Mirror World, you will not die from combat, but if you are defeated in the real world, you die. If your Contract Beast is lost, you will no longer be able to use your cards.
