シルフ

One of the four great spirits, Sylph rules over the wind. Though she's a type of fairy, her magic far surpasses a normal one. Since she is averse to battle, Sylph is unable to properly use her powerful magic in a fight. Even so, she isn't an opponent that a normal adventurer can handle.

Due to her fairy nature, she loves playing tricks on people. Interested by male genitalia, she will use her wind to play with men until they ejaculate. In addition, she absorbs male semen to replenish her magic.

Though she has a physical body, she is able to turn into a spirit body. Using her spirit body, she can possess a man and allow him to use her powers. However, the man needs to be very skilled to manage the enormous magic Sylph holds. For that reason, the spirits will only give their assistance to those they deem worthy.
