Angel Olivia appears out of nowhere in front of Dark Warrior Aeron. She claims that she went through numerous obstacles just to come to see Aeron. Aeron, who had no interest in women before, is shaken after spending time with Olivia, who conveys her love to him with her purest heart. Aeron can't accept her love since he is a sinner, and he does not think he is a match for an angel. At the same time, demon Legion becomes very jealous to see Aeron being so stirred by Olivia and eventually makes a deal with Lucifer, the Prince of Darkness, in an attempt to possess Aeron for herself.
