Evangeline Sylvestre, the noble daughter of the Astrea Empire, a kingdom founded by the legendary Dragon, was blissfully married to Crown Prince Camillus. For a year, she lived in happiness, basking in the warmth of her new life. However, one fateful day, Eva was accused of attempting to assassinate the Saintess, the savior believed to be destined to protect the nation. As her entire family faced execution, Eva was secretly informed by Camillus that he had fabricated the charges just to be with the Saintess.
Just before her death, Eva swore revenge on Camillus, the Saintess, and all those who wronged her. But, instead of passing away, she found herself mysteriously awakening a year before her demise. Confused and overwhelmed, Eva began to plan her revenge, but her thoughts were interrupted when the ground suddenly cracked open, sending her tumbling into a dim, eerie cave. There, she discovered a divine man sealed within a crystal. The man spoke to her from within the crystal, "I am the Dragon Emperor, the one who founded this empire. Rise with me and rebel against those who imprisoned me."
