You live a simple life in a small fantasy town. You have few talents except the ability to magically tell if someone is lying.
Once news comes that the king has died of old age and that his daughter, Princess Selena, is coming to your city for her coronation. When a person close to you is soon killed, and you find out that you are the only person who can save the world from an unidentified disaster, everything becomes quite hot.
Serving as a powerful sorceress, you learn to manipulate people's minds. With this knowledge in hand and with a little pixy, you are ordered to prepare for the arrival of the princess so that you can seduce her and save the world (the details of this elude you). Until then, however, you must practice. How attractive that this practice means using your magic to seduce as many girls of the city as possible.
Life is about to become ... exciting.
