Ten days. That's how many days we have left, and how many days it's been since everybody on Earth received the same message in their head. "Prepare, for you have 20 days until your world as you know it, is gone. Your world is to be merged with another. This world is much stronger, more primitive, and extremely cruel. Your pitiful strength will be your ruin. Therefore, the gods of MERCI have smiled upon you. In 20 days, you will all be summoned into a simulation world. In order to obtain the strength needed for survival, you must fight. Your lives, are in your hands. Prepare."
