A/N: This has been revised a tad, trying to make up for my absence… *feels bad*.

This is SLIGHTY AU. I will stick as closely as possible to the original storyline, HOWEVER! There will be things that are different so… yea…

Summary: Bel is a prince, though he was the younger prince, he wanted to be King, and this desire was shared with his elder brother Rasiel. They hated each other because of this, and one day, when they were 4, Rasiel had something done to Bel. When Bel finally escaped, he joins the Varia, in order to get revenge on his brother. He befriends Mammon, and they soon become the best of friends, but then one day, Mammon was killed by the Millefiore family, which Rasiel was part of and he realized then that his brother had taken away EVERYTHING from him, his status as royalty, his "human" emotions, his life, his best friend. Then comes along a "replacement" for Mammon that Bel instantly despises… or does he? What will happen now that Bel has finally found his precious "someone"?

WARNINGS: Is rated M for Gore and Violence! (Lemon… not planned at the moment.)

*A Fallen Prince – Chapter 1*

~*When Bel was 4*~

"WHERE THE HELL ARE YOU TAKING ME? LET ME GO, YOU FILTHY BASTARDS!" a blonde little boy was held by the arms as he struggled against the strong grip of his mysterious kidnapper. He was being carried through a long, dark hallway; the metal looked old and worn. The place reeked of chemicals, and other substances that he could not identify.

"Ushesheshe~!" almost immediately the captive blonde prince, whipped his head to face his "older" brother, Rasiel, or Siel (pronounced Jill in Japanese).

"THE HELL JILL! LET ME GO!" Realizing who the mysterious stranger must be, he shouted "ORGELT! AS THE PRINCE OF THE ROYAL FAMILY, I DEMAND THAT YOU LET ME GO!"

"I'm sorry Master Bel, but I only serve the prince that will one day become king, and that is Rasiel-sama," the largely built butler's grip on his arms tightened.

"USHESHE SHE SHE SHEE! Stupid little brother, that's right, I'm going to become the King, and you'll just be trash in the sewers," Rasiel broke into a laughing fit before continuing, "I hope you have a nice time here, I made sure to tell the people here to take EXTRA good care of you~! Usheshe shee~" Rasiel looked as if he was on the brink of collapsing of laughter, ecstatic even. They were approaching a menacing metal door. Bel scowled, and let out a growl; the panic and fear he was feeling grew. The door creaked open, Rasiel exchanged a few words with the people inside, and came back grinning ear to ear. He whispered something to Orgelt. Orgelt immediately stepped through the door with the thrashing Bel.

"LET ME GOO! HOW DARE YOU TREAT A PRINCE THIS WAY!" he spat at the people around him, "RASIEL! WHEN I GET OUT OF HERE, IM GONNA COME AND FREAKIN' KILL YOU!" Bel roared, as he was tossed into the hold of 2 other people.

"Ushesheshe~ As if you will ever get out of here, Bel," Rasiel said as the metal door creaked closed.

"Tsk, LET ME GO!" Bel screeched at the top of his lungs, he thrashed around in the hold of his captors.

"Hmm~ he's such a nice specimen, perfect for our next experiment," a black haired man with half framed glasses was observing him, he was an average looking middle aged man, nothing special about him, except for the fact he looked like a pedophile. His hand cupped Bel's chin, no later did the man touch him, did Bel bite at the offending hand.

"Wow, feisty too, AHAHAHAA~ but I think you should be a bit more cooperative little fallen prince," the man sneered as yanked at his nice blonde locks of hair, he pulled out a long cloth from his white lab coat, and instead of tying it around his arms, legs, eyes, or mouth, he tied it tightly around his neck, restricting his airflow. Two subordinates rushed up to the black haired man.

"Dr. Shiki, the materials are all ready for the experiment, Main Lab Room #1 has been prepped and is ready to proceed with the experiment," the two said as the accessed Bel.

"Ahhh~ perfect! Hmm…. From today on little "prince," he sneered at the word, "You'll be known as B2, and you WILL listen to us and be good." Bel wanted to spit in the man's direction, but the needle that was held in the hands of one of the men there was HUGE, (and he was a 4 year old, you can't blame him!) he whimpered.

"There there, now that's a good boy!" Dr. Shiki patted him on the head, Bel wanted to disinfect and/or rip off his head immediately, "Okay strap him down to the table in Main Lab #1, remember to gag him, don't want him alerting others of what we're doing here," the man said smiling. Bel could not see his captors nod their heads, but he knew they must have when they started moving. He was carried through the dark hallways that twisted and turned like a maze, before they suddenly stopped in front of a door and opened it.

The inside of the room was blinding white, so white that it hurt your eyes, and in the middle of that room lay a table with thick leather strap restraints. But Bel's eyes were looking at something else, they had widened in horror at the utensils laid out on the tables, needles, knives, scalpels, weird chemicals, everything was laid out neatly on the table.

"No…." he whispered quietly to himself.

"NOOOOOOOOOO! LET ME GO!" Bel jerked one of his arms out of the grip of one of his captors but his arm was quickly caught again, but this time, there was a hand wrapped around his neck, choking him, the cloth around his neck slowly dropped to the floor and laid there forgotten. His head made contact with the metal of the table, he trashed and clawed as hard as he could, but he could not break free. He was quickly strapped to the table, tears streamed from his bright amethyst eyes.

Dr. Shiki finally strode into the room with his doctor's gloves and mask. His eyes smiled deviously, as he popped a gag into Bel's mouth.

"Well, let's begin now shall we?"

Bel watched horrifically, as they picked up the needles, and filled them with strange liquids.

Slowly the door closed shut, but even through that thick metal door, you could still hear the pained screams of a little blonde prince. All through the night could you hear those agonizing screams, but when dawn finally breaks, the screams have gone away, and instead it was replaced by the whimpers of a frightened young boy.

'Once I get out of here, Rasiel, I'm gonna fucking kill you, ohh and not just kill you, but in the most painful way possible! I'm going to tear you limb from slowly, and torture you until you finally die. USHISHISHIII~'
