ch 1-7

"To me, you're also a woman."
A cocky sadist with dual personality "Goat" and a head-strong delinquent "Wolf". One’s unstoppable when his mating period kicks in! Today, he’s in for sex even if it’s by force! And the other one’s too lewd for a beast that even a woman would be put to shame!?

In order to protect his people from attacking demons, Prince Val uses a demonic sword and curses himself in the process. He leaves his kingdom to find a cure, and his search leads him to Hallwil, the person rumored to be the only one who knows how to break the curse. Hallwil agrees to help Val... for a price.
