Chapter 1: The Living Gun, The Watchdog.

"Lucille I will tell you a story, it's the story of a witch and a wizard."

The ragged old woman said petting the child's hair.

"It's about how the wizard and a Dirty Blooded witch woman met" she continued, watching as her granddaughters ears perked.

"They fell in love...after the wizard fought many years to gain hers though and they married happily together. And then a bad man came"

"Then the witch found herself with child. And nine months later a beautiful baby girl and a boy were born, with the prettiest Emerald eyes and the silkiest raven colored hair while the boy had smooth chestnut eyes and hazelnut colored hair.

Dorea started to braid her granddaughter's hair. The child smiled up at her in confusion not quite understanding.

"The bad man tried to kill her parents, one night a curse he cast one that killed immediately but the baby girl blocked it, in effort to save her brother. The old man came and claimed the boy as the savior"

"The little Girls name was Lucille See that's your story Pup and someday you will add more."

The girl giggled in delight as her grandmother tickled her stomach and finally a few minutes later she was lulled into slumber as she listened to her grand mama's heartbeat.

"Remember little guardian. The fate of the worlds, rest in your hands"

Lucille woke up with a gasp, she never thought... no, it was nothing just a dream.

The emerald-eyed girl held her hand up to feel the familiar wet trails going down her cheeks.

The raven haired ten year old groaned as she wiped her tears and once again, pretended she was listening attentively to the teacher who drawled on about math... or something.

She heard the quiet humming of the boy behind her a possibly a pop song on the radio or a random tune.

She felt her mind wandering and thought about the dream she hasn't had it in years. Why was it here now and finally she started to curse internally, cursing her damned father and mother for abandoning her, the world for taking grandmother Dorea from her and finally cursed the Dursley's For abusing her she at

Least was smart enough to know children weren't treated like she was.

Finally the bell rang, Lucille grunted and stood up stretching her arms out and picked her bag of the floor and walked out the door and heading for the school entrance not patient enough for Dudley but knew she would get a beating out of it but it happens everyday anyway.

Ignoring her female classmates gossip and her male classmates annoying jeers, and dear Dudders Lame attempts at getting the new kid to hate her; she quickly walked to a less used route and let out a long suffering sigh.

"This is hell" The Potter let out, and stopped by a winding road near the highway glancing left and right and checking for cars and finally nodded to herself, walking out to the street she heard the unmistakable sound of a truck and started to walk faster the other side of the road looking infinitely farther the sound was close she started to jog and finally she sprinted.

Lucille Jamie Potter flew into the air as the truck hit her head on black hair waved in the air as she hit the ground, she felt the bones break and knew the blood was pooling and then...she was floating.

She gasped in shock in front of her was a wraith like apparition. The thing was a murky black/brown color and covered her ears as a high pitched keening noise came out of the creatures or what she assumed was the mouth.

And finally after the creature stopped its horrid screaming, Lucille sighed in relief. Then screamed, as hundreds of thin black chains wrapped around her body and red chains wrapped around the wraith.

And finally it went black.

Lucille groaned pitifully, and tried to pry her eyes open. Only to be met with three pairs of glowing red eyes.

Screaming she shoved herself back until her back hit a rocky wall.

Suddenly a strange baritone voice boomed,

"Abandoned Child, Daughter of Darkness and savior of light, guardian of thy worlds, thou dark lords slivered soul has been destroyed but many remain do thy accept thy responsibility as Gatekeeper?"

The voice belonged to the large three-headed canine in front of her!

"Once again I ask of thee! Do thou accept?"

Despite what her ten-year-old mind alerting her, she responded anyways.

"Yes" she whispered.

"Go! Go! To the man riddled with guilt, a boy controlled by a woman unknown and a child who has forgotten all love but his brothers."

The voice said much more gently.

"Y-yes" she said stammering but louder.

Suddenly the large three-headed dog shifted and churned its form turning into a spot of black and seemed to turn into an orb of glowing darkness that seemed to suck in any light in the dank cave, and suddenly it sunk into her chest.

Slowly dark blue fog started to fill the room and suddenly she couldn't breath and for the second time that day she fainted.

Vincent Valentine had just turned twelve! Mother said that was good since he was going to be a big man!

He was so Excited, Lucrecia was going to come over but on another note so was Hojo.

The Eldest Valentine sighed sadly he didn't like that Hojo would be there, the boy was older than both of them nearly 14 but he sent chills down the scarlet-eyed boys spine.

Vincent being preoccupied with his thoughts of creepy older teens suddenly noticed he was in a cave...a very pretty mako cave. The red-eyed boy stared in awe as he took in his surroundings before he heard...was that humming?

Walking forward his black boots making a rather peculiar squish sound, eyes still wide he approached a pillar made of what seemed to be black stone with flecks of rainbow (A/N: yes it's opal you will se why later) and smack dab in the middle was a portion of stone colored a shimmery white.

Laying his hand on the unnaturally smooth pillar he jerked back, whispers filled the air as he once again laid his hand on the pillar; the voices were eerie filled with songs of heroes and dirges of their sad ends (A/N: yeah I know what I did) he stared in wonder as thousands of legends were told in a span of a few seconds.

But one rang in his ears, a song about a three headed guardian the name wasn't clear but, but, he knew its name so familiar like he knew it since birth.

"Cerberus" He breathed out airily.

Suddenly something seemed to burst the whispers came to a immediate halt, as bits of mako and strips of light flashed around him as the pillar started to do what seemed like melting.

Finally it was done the colors died down and the debris settled Vincent once again found himself in awe on the now on top of the half melted pillar was a three barreled, triple cylinder, revolver. On each barrel a small silver dog head was carved and down the revolver delicate script swirls decorated it finally coming down to the brown wooden handle and a chain and charm of a three headed dog and a wing hanging from it.

In a trance, he strode up to the pillar and pulled on the cylinders. Finally moments later the stubborn stone let the gun free as he stumbled, revolver in hand and fell on his butt gracelessly.

Standing up patting himself down for imaginary dust he once again brought the gun up studying its designs and general structure. It was a revolver all right though unique everything on seemed to be tripled.

"Hello? Hello? I don't know where I am!"

He gasped and nearly flung the guns away from him if it wasn't for the fact it seemed to stick to him, like magic really.

"Um...hello my name is Vincent w-who are you?" The Valentine spoke stammering a bit.

"...Vincent...what a nice name...my name is Lu- I mean Cerberus" the feminine voice replied by the sound of it, Cerberus he deducted was a young girl close to his age.

"Where are you?"

"Right here silly!"

"W-where?"

"Look down" Vincent did as ordered only for his eyes to rest on the revolver.

"Y-you're the g-gun!?"

"Well that is plenty rude! I'm not a gun I'm as human as you! Or welllllllll, used to be..."

"Then, what happened?"

"Well Vincent dearie you know how you never ask a lady their age?"

"...Yes"

"It's one of those moments~" the disembodied voice of Cerberus sang out.

-(Because the Authoress is lazy she will be skipping a few years)-

Vincent had grown, Lucrecia noticed and painfully handsome to.

She herself was proud to say she was the center of the raven's metaphorical world.

In all honestly it was sad that she didn't know that Vincent's center was Literally his revolver. Ah well she did not need to know that! Does she? Hmmmm.

Lucrecia stared longingly at the Turk trainee, then glanced at the glaring Hojo, then back to Vincent. Really if it weren't for the plan she and Hojo had then she would be romping on our dear Vinnie's bed by now...(A/N: can't believe I just wrote that).

But of course she just had to be pregnant with said scientists experiment oops she meant child. Yes child.

Vincent Valentine was not an idiot. Cold? Yes, a Turk? Yes, Antisocial? …

Does a ducks ass look like Sasuke's hair?

In other words! Hell to the yes! But an idiot? No, siree!

He knew that Hojo was up to something.

"Ooh! Absolutely nefarious! Tell me more!" The mental voices of his weapon butt in.

"Cerberus, what have I told you about messing with my train of thought?"

"..." She stayed silent.

"Cero?" He asked again mentally and impatiently.

"...Not to" the Guardian replied.

He once again gave a long-suffering sigh and continued down the Shinra hall, shrugging off Hojo's glares.

Lucille hated lying to Vincent, loathed it! But for the past few years it had been one absolutely grand one.

Walking along the lush, luxurious mansion that was her Vinnie's Mind, poking stray thoughts away, she stopped by a large barred door.

Mentally debating whether to open it or not, nodding she opened the door and walked to an iron-grey cage...she needed help.

Lucille wasn't all-powerful. Far from it actually, she was a weapon not the user, but she needed to learn how to protect herself and her wielder.

Especially, Vinnie. Vincent could be reckless with his life, taking on missions above his trainee status. She knew he was going to be promoted to Turk in a week but still she worried.

Because, in her mind she knew she would do anything for Vincent; even if it meant ripping the stars from the sky and tearing the world apart she would protect him.

Even if it meant making a deal with Him.

"Hello...Chaos"
