This was inspired by reading various Hellsing fanfics posted here, and as I can't remember which exactly and I may have accidently pulled a few details from something somewhere, I choose to give credit to everyone! Yay!
I suppose this was mostly written to combat writer's block and figure out Seras' character, since I'm a bit stuck on The Will to Live. It's sort of AU if you're going to be picky: it's a situation that couldn't really happen in the manga, which is my primary basis for what I write. It could work in the anime, although it already has a scene in it where Seras takes her first blood. But I think it's more out of hunger then, this is a description of the first time she willingly takes blood as I see it happening. But, honestly, it's a oneshot without any frame of reference in terms of time, who cares if it's a little AU.

My eyes were unintentionally transfixed on the packet of blood in the center of the table, resting in a bucket of ice. As much as the concept of drinking blood repulsed me, I was drawn to it, desiring the metallic red liquid more than anything else in my life.

My master would often chastise me, proclaiming that my refusal to drink blood was tantamount to rejecting my own nature, to desperately clinging onto humanity and refusing to become the monster I was.

I found myself doubting that it was truly as simple as that.

I knew with more certainty than anyone that humanity was not something that had to be discarded to become a monster. I had watched two men, two human beings, murder my parents, watched as they raped my mother's dead corpse. And I, a human being, had attacked them with the only weapon available, a fork, succeeding in blinding one of them in their left eye. When I had entered the police, I had hunted down many humans who had become monsters, allowing themselves to succumb to a darker, more primal side of themselves. And in hunting them, I myself had become a beast, a monster capable of dealing death.

Yes, humans were just as capable of atrocity as vampires.

And yet, as a human, I had been instructed on what was accepted and what was not, what was considered devious and what was considered harmless. As a police officer, this forced system of morals had been asserted even more strongly, overwhelming my own concepts of humanity and what was right and what was wrong.

Perhaps I was clinging to the lessons of humanity because I had been forced to conform to them in life.

This one idea infuriated me; I had never been one to conform. In the orphanage, I had refused to act as something that I was not for the sake of adoption. I would fight, laugh, and live on my own terms. When was it that I had stopped fighting, that I had accepted their morals and their norms?

I moved towards the table and snatched the blood from its resting place in one quick motion, not even a hint of hesitation in my actions. I tore into the plastic and allowed the sinful liquid to flow into my mouth, down my throat.

I felt no different from before physically, the only noticeable change being my now sated hunger. Yet something had changed, something within me had grown. I would be slave to no one's expectations, I would conform to no one's standards. I had released my last hold on the humanity I had unintentionally and unwillingly clung to.

I stumbled a bit at the end, but I actually rather like how this turned out, I think. Please review!
