Milene, a novice mage who lives with her sick father.
Her dream is to save her father with magic. For that, strong magical power and funds are required.
However, Milene, the lowest in the Mage Association, did not have both.

An event will occur that will change the future of Milene ...
She happened to know a "secret" that only a female mage has.

It was a forbidden curse that would allow you to increase your magical power without rigorous training if you enjoyed the spirit of a man.
For Milene, who has a serious and unobtrusive personality, this secret was astonishing.

Furthermore, at that timing, he even came to a request to investigate an ancient temple infested with monsters.
This may be a chance to change myself, who could only do chores, and save my father ...
Milene is forced to use the desires of men little by little for the purpose ....
