Once upon a time there was a girl who was nice and innocent, the picture of the girl that guys want to take home to mom. But men are unreliable creatures, all her life she was able to easily snag guys with her sweet personality and develop meaningful relationships.

Unfortunately, despite having a genuine connection with these men, they grew tired of waiting for her to allow them to take out their lusty desires and moved on to the more 'easy' women. This was the existence she lived, constantly cheated on and finding her love with another.

This created a fissure in her heart.

That is until one day she had thought she had found the perfect man, he never showed the tell tale signs of becoming bored with her, or being interested in another. They eventually got engaged.

Though this story doesn't end with a happy ending, at least the kind of happy ending that one would expect, for one night she came home to find the love of her life wrapped around another woman. In fact that woman washer best friend and soon to be maid of honor.

The rage and hate that had manifested in her heart since her first young school girl kiss burst forth all at once, widening the fissure in her heart and soul.

This intense hatred happened to pique the passing attention of the lord of Gehenna, Satan, himself.

He briefly observed as she brutally murdered and mutilated the bodies of her fiancé and maid of honor. Once the deed was done she swore to pay back what men have done to her ten-fold.

It was there, laying in the blood of her love and best friend that Satan appeared before her and offered her the power to exact her revenge, to allow her to torment men for eternity.

She accepted.

And so Satan used the fissure in her heart to turn her into a demon of temptation, a Succubus.

So the entity of hell, (y/n), was created.
