<Female name here> finds an old dusty trunk in her recently deceased father's attic, the bronze lining engraved with strange symbols she had never seen before, she thinks nothing of it given that her father was an eccentric whom was always bringing some weird something or other home to be tucked away in the attic.
It didn't surprise her too much when within her father's will was a sealed envelope addressed to her, within simply requesting that she either leave his belongings in the attic as they or have them sent to the son of a colleague of his. As if touching any of it was some sort of big deal or something.
Never once does she have the slightest thought that maybe opening the trunk is really not such a good idea, that maybe... JUST MAYBE... the trunk houses something that was never meant to be released...
For instance... a sensual chaos demon responsible for mayhem around the world for centuries... imprisoned by her father many years ago and sealed away inside the trunk, the runes on the bronze lining serving to keep him contained for eternity.
Her father's reason for wishing her to refrain from messing around with his things? His spells can be undone, only by the doing of one belonging to his bloodline.
So what happens you might wonder when she does open the trunk? The powerful being within is released and before her stands the most beautiful man she has ever dared to imagine in her entire existence...
Lucky for her however, the demon became spiritually bound to her when she opened the trunk, giving her a metaphorical leash of sorts on the demon. She can't really control him too much other than for example, forbidding him to do harm to humans.
His only chance of regaining his freedom is through his lovely 'warden' to verbally come right out and saying “<Name here>, I release you”
Let the chaos ensue!
