This story is loosely based on the Steven Universe Occult AU, which has Rose as a vampire, Pearl as a vampire-hunter, and Amethyst as a werewolf.

It had been nearly a month after the werewolf's brutal attack on Amethyst during a secret cage-match she had been forced into by a group of evil vampires.

"It's a Fight to the Death!", called the announcer. "Place those Bets!".

"How could I have let this happen to me!", thought Amethyst as she stared wide-eyed at the ferocious beast approaching her.
Luckily for her, Pearl and the honorable-vampire-Rose had rescued her just in time, Pearl staking multiple vampires in the rescue.

Rose herself slew the werewolf with a mighty thrust of her blade as it turned to face her. Letting out a deep breath she knelt beside the injured Amethyst, three long scratches on her shoulder deep enough to have drawn blood.

"I'm so sorry.", Rose said to her, knowing what the next full moon would bring as she offered her hand in assistance.

Vaguely Amethyst remembered being helped up before staggering and then being slung over Rose's shoulder and carried out. There were several loud bangs and screams followed by bright sunlight, and then...

Amethyst had slept for a full day before regaining consciousness, awakening to the concerned smiles of Rose and Pearl sitting by her bedside.

In the weeks following the attack, Rose and Pearl explained all they knew of werewolves to Amethyst.
"Sooo, you're saying on the next full moon, I'm gonna turn into a werewolf and eat people?", asked Amethyst incredulously.
"No, with any luck you won't be eating anyone.", said Pearl. "But unfortunately you ARE a werewolf. Right now, and on the next full moon you'll turn into... An animal."

"Sooo, like, what am I supposed to do on the next Full Moon?" asked Amethyst, slightly annoyed. "I can't be around anybody. The last thing I wanna do is hurt Steven."

"Yes, we thought about that." answered Pearl. "You're pretty strong as your normal self, but as a werewolf you'll be Much stronger. I don't think we have any cages that could hold you, quite frankly."

"Gee, thanks for the compliment.", huffed Amethyst, blowing the strands of hair that had fallen in front her face.

"So we've decided.", continued Pearl, "to drive you out into the wilderness, away from Beach city, where there's no one around for miles. But this is just a temporary solution until we can find someplace that can hold you."

"Eh, sounds good to me." answered Amethyst, closing her eyes as she put her hands behind her head and leaned back in her chair. "The fresh air'll do me good."
Pearl smiled reassuringly.

The next few weeks passed fairly uneventfully. There was a volleyball-match she had with the other citizens of Beach City, and they wondered as Amethyst had seemingly become more athletic since their last game. This prompted Steven to ask questions, leading eventually to her explaining her condition to him during an eating session at Kiki's Pizzeria.
She wore her usual look, her hair tied neatly into a ponytail in the back. She looked to all as though the attack had never happened, except for the three faint claw marks which would still be visible on her shoulder were it not covered by her casual white shirt.

"So in five days you're gonna turn into a werewolf." He said, as if in disbelief. He had hardly touched his pizza, which was unusual for him.

"Uhhh!" breathed Amethyst in annoyance, rolling her eyes. "NO, Steven! I AM a werewolf, and in five days I'm gonna change. Into this -Monster. With fur, and huge teeth... It won't be anything LIKE me."
"SO," she continued, "Pearl is gonna drive me out of town, far away from any people so I won't hurt anyone. Hoooopefully.", she said with another eye-roll.

"Is there a cure?" he asked

"We're lookin', but we haven't found one yet." answered Amethyst dryly as she drummed her fingers on the table.

"So, are you nervous?", asked Steven.

"PSSSHHH, Yeah, kinda.", she answered, looking upward and running her right hand through her hair as she thought. "Like, what if there's a hiker or something out there? Pearl says that it'll be too far for me run all the way back to Beach City, and that my wolf-self won't care to come back here anyway, but Pearl's not always right."

"She does know more about werewolves that you do.", said Steven smiling reassuringly.

Amethyst chuckled. "Yeah, she admitted."

"So, the transformation, will it hurt?" Steven continued.

"Yeaaah", answered Amethyst. "Pearl says it'll hurt, like a Lot. But I'm a wrestler, I'm a fighter. I'm no stranger to pain.", she smiled.

"Now let's finish this Pizza!", she said before happily munching her slice which had almost literally everything on it.

That's my first chapter based loosely on the Steven Universe Occult AU. A future chapter will describe Amethyst's transformation, along with possible romance with some other female character. I'm not sure yet, but I've rated this story M because of it.
