Isaura thought she was the last wizard remaining in the universe. However, it turned out to be more than that; her birth was a decision by the Gods to defeat the evil power that had been defeated by Isaura's great-grandmother, Mathilda. Knowing that Isaura couldn't handle everything alone, the Gods sent Arthur—the God of War—to accompany Isaura on her journey. Arthur was born solely to be Isaura's guardian. Did Isaura succeed in her mission or falter along the way? Who was Mathilda in the past, capable of burying dark forces? And what is the fate of the universe when dark powers begin to emerge? The force that Isaura and her friends face is not just any ordinary demon. He is the ruler of darkness. Something that cannot be killed like living beings.
