In the dark, filthy mines of Endromeda, a sixteen-year-old blind girl is serving her life sentence as a slave, bound to spend the rest of her life mining mana stones for the tyrant emperor. She is known as the blind manhunter, the best within the assassination guild, but she was betrayed by her sister. The Duke of Sharbel, previous crown prince, Quentin Azulon, came and struck a deal with her to marry him, be his wife by day and be the empire's assassin by night. The blind Celena Raveniel agreed and started to plot her revenge against her sister, who stole everything from her.
