On April 12, 2017, the earth fell!
Countless fantasy species descended on the earth from nothingness. They possess incredibly powerful power, but have no thoughts. Their only instinct is to kill humans and devour the existence of humans themselves.
Just when mankind was in despair, characters who only existed in the second dimension appeared on the earth one after another. The "eternal seventeen-year-old monster" - Murasaki Yakumo, the "Queen of Ice" - Esdeath, the "Cold Lord" - Orochimaru, the "nightmare" - Kurumi Tokisaki...
Under their leadership, humans and fantasy species launched a decisive battle, but the result ended in failure. Only 3 million humans were left and retreated to a different space, where they established the last pure land - Fantasy City.
And more than ten years later, a boy named "Xi Muye" woke up from his deep sleep, only to find that his sister was Wuhe Kotori...
