Devoted Knight Kuon has been a close friend of Princess Dia since childhood. Six months ago, the king of this nation died, leaving Dia as heir to the throne. Everything seemed perfect until a scheming minister tried to usurp the throne!

Working alongside the evil knight Wart, the minister overpowers Kuon and captures Princess Dia! To stop the minister from seizing power, Kuon takes the royal ring from Dia and becomes a fugitive. Will Kuon be able to defeat the evil minister and his knight Wart? Or are both ladies doomed to become sex slaves for life?

As Kuon explores a hidden forest, she discovers the grimoire of the female demon Empusa. Empusa offers her a deal. Kuon will become far stronger, but in exchange, Dia will become super slutty!

While the minister spreads rumors that Kuon tried to usurp the throne, Kuon focuses on finding Master Boro to aid her in her quest. Boro was the right hand man of Kuon’s father, so he has great skills in intelligence gathering that will help Kuon on her quest.

At the end of the story, Kuon is forced to face a werewolf and the dark knight Wart! If she fails, she will be enslaved! But if she wins, she will be free from her contract with Empusa, and Princess Dia will finally be crowned Queen of the kingdom!

Overall, the story is simple and easy to follow. It is forgettable overall, but fun while it lasts.
