A powerful beast sought out for more power. He was told by a gypsy that if he found a maiden he would gain power like no other. In search of the maiden, the beast took the form of a young man named Jang Hyunseung. Fooling all the humans with his kind actions and godly features, he killed thousands of women to find none of them held the power the gypsy spoke of. That was until he met a young woman named Son Haewon. A beauty so subtle that even his hawk-like eyes could miss. Is she the one to help the beast rein power over the entire country?
