Summary: It's been 4 months since Dean took the plunge to hell. Desperate, Sam chases for something… or someone, most hunters and even demons deem as myth. The Master of Death… wait a minute, The Mistress of Death?!

Disclaimer: I love Harry Potter and Supernatural, sadly I don't own them… Cause if I did the stories would be a hell lot different. For example, they would all be gay… If I was in charge. *sigh* If only.

Pairings: Sam/Harry/Dean, Sam/Harry, Dean/Harry. No Wincest fangirls, sorry!

Warnings: Like I said, NO WINCEST… That means no Sam/Dean, people. Genderbend!Harry. Mistress of Death shit that I made up… or so I hope, I guess (Don't hesitate to tell me if someone has already done this in the HP/SPN universe). Some Ruby bashing (Don't get me wrong I love Ruby –especially in the 3rd Season- but she can be a bitch sometimes). Aaaand… Swearing. Well, anyways that's all for now (I'll add some things along the way)…

Author's Note: I probably shouldn't be doing this, I have two fanfictions I didn't finish (I'm sorry, I lost inspiration… That, and I moved to the HP/SPN family) and exams (big problem men!)… Buuuut, I am. So guess what? F*ck the exams on Thursday!

Aaaand, before you guys rant about my possible laziness… I have something to say.

This particular plot bunny has been bouncing around me for weeks! And its getting so damn annoying that well… here we are. And no worries people, Supernatural is quite loooong series and let's face it Harry 'freaking' Potter is timeless… So no worries with me loosing inspiration~! So enough with the chatter. Shut your cake holes people and let's get the show on the road, you wankers!

~Prologue~

"Under certain circumstances, urgent circumstances, desperate circumstances, profanity provides a relief denied even to prayer."

-Mark Twain

Harriet Lily Potter, or Harry for short, stopped on her tracks. She was on her way to Hermione and Ron's house for a spontaneous visit but it seems like there's a change of plans. Tucking her long and curly hair behind her ear, the petite girl sighed. She didn't expect to feel this pull for another hundred years or so. It seems like she was wrong. Who would be so desperate to take a so called myth seriously? It seems like there's only one way to find out.

With a blink of an eye, Harry disappeared.

I'll get Dean back no matter what it takes.

Sam Winchester was a man with a purpose.

And what is that you say? Try getting your older brother out of hell… literally.

He searched all the books he could think of, all the demons he could summon but none of them was of any help. All the books he found were either a dead end or rubbish and none of demons wanted his soul. He was running out of ideas, and he was just about to give up when he came across something.

The Conqueror of Death… Vanquisher of Death… The Master of Death.

Sam asked Ruby about it, but she waved it away and said it was nothing but a myth, and that he should focus on training instead. Of course being the stubborn person he is, he didn't listen and instead started to prepare the ritual for summoning this myth.

And thus, it led to this.

"Hello, my name is Harriet Potter, call me Harry for short!" the girl announced smiling politely as she held her hand for a hand shake.
