Lily—said to possess the greatest power among all saintesses (those with restorative abilities) throughout history.
Serious and diligent, Lily poured out her power unstintingly every day for her country and its people, continuing her selfless service.
One day, however, she and her parents are brutally slaughtered by the rival saintess Azalea, who nursed an inferiority complex toward Lily’s power…
Lily cries out words of a curse. Drawn to her soul, the Incubus Demon King Kiel grants her demonic power—trading it for her “finite holy power” and “sexual pleasure”—and she is brought back to life.
Will Lily be able to exact her revenge before her holy power is exhausted?!
What fate awaits their forbidden love that transcends even the incubus race…?!
