The entire world around him freezes except for two monsters that begin to devour the frozen people. Upon seeing him move they call him a "Mystes" and try to kill him. Then a mysterious girl with hot eyes and long flaming hair comes to his rescue. She brings back all the people that were devoured and unfreezes the world. According to her she didn't bring them back, but created temporary replacements.
