I couldn't fit this into the summary so I'll just say it here. This story would probably make more sense if you've watched the Bleach Movie, Hell Verse. Oh and there may be slight Hitsugaya/Karin or Ichigo/Rukia in future chapters. Although the story is not centered around romance. (Or Karin)

The loud thunder boomed, shaking the very core of hell. All the sinners were running around in chaos. Hell had been in chaos before, it was always in chaos. But this chaos meant something even more. Something very bad was happening.

In between the loud pauses of thunder, hell was eerily silent. Almost as silent as midnight. Everyone was terrified. Some people were trying to be hopeful. Others were shaking and trembling fear. No one dared to speak for breaking the silence would only have made things worse. Doom was sure to come. That message was very clear. Perhaps fate would finally destroy them once and for all.
The most terrifying thing of all, was the fact that not one Kushanada was in sight. On a normal day, this would have been a miracle for sinners. But today, it meant only the worst was to come. Nothing was normal about this day. Nothing at all. Thunder was booming from hell. That wasn't supposed to happen, ever. The Kushanada were no where to be found. Even those that had lost all ability to think could tell there was something horribly wrong.
After a few, long and agonizing hours the thunder finally fell silent. Only instead this time, it didn't start up again after a minute or so. All was quite and silent. Minutes later, the sinners began whispering amongst themselves.
"Is the earth ending?"
"It's the apocalypse. . ."
"Maybe hell is crumbling!"
"No, something is horribly gone awry."
"Something must've gone against the laws of hell!"
"Do you think maybe someone broke free from their chains?"
"Don't be stupid. Nothing can break these chains."
"Then why is it so wrong here? You can feel it, I can feel it. Something in the air is wrong. It just isn't right."

A deep rumbling sound came from within the depths of hell. All sinners fell silent once more, holding their breath. The ground groaned and shook. Was it an earthquake in hell?
Finally, a high-pitched roar rose. It was more sinister than an animal-sounding hollow. It was much more sinister than the roar of a savage beast as it lunges towards your neck. All the sinners screamed in agony. Screaming with the beast from within hell. Every single sinner lifted their hands in unison and covered their ears. The terrible things that only they could understand from the beast made them want to die, gone forever. They wanted to become the crushed sand of sinners.
All the sinners cried out, curling up into the fetal position and held tightly to their ears. Some of their ears even began to bleed from the roar of the beast.
Finally, at last the roaring stopped. Everyone breathed a sigh of relief. No one knew what was happening. No one knew what that beast was. But one thing they all did know, was that a beast had awoken from its deep slumbers within the chambers of hell.
At last, the beast opened it's eyes, and shut it's mouth. It slowly began to awaken. It was nearly impossible to see it in the darkness. The beast was within the very core, the center of hell. Slowly, it folded in it's red crimson wings, stepping in out of it's little cocoon it had encased itself in. For the first time ever, it had folded in it's bat-like wings, and woke up.

The beast's eyes were completely black. Devoid of any emotion at all. It's face looked like a pale woman's with long and black flowing hair sprouting from the scalp. The hair reached down all the way to it's feet. Two long horns stuck out on top of it's head.
She yawned as if waking from a little nap. Her teeth were sharp, sharper than a knife. She looked down at her naked body and frowned. Holding out her hand upwards, the ground above rumbled a bit. Then a sinner, bound in chains came shooting through. Dust flew everywhere as she came flying straight into the beast's hands.
The sinner looked into those black eyes, terrified. She was being held by the throat. "P-P-please...d-d-don't," the woman stuttered. "I've seen your sins. Your wrongs. Suffer once more." A long tail unraveled from the woman, or demon, whatever she was. The tail was long and slender with a little sharp arrow as the tip for it. The arrow pierced the sinner, straight into the heart. Or at least, where the heart used to be.

The sinner screamed, screamed and writhed in pain she had never known before. She was relieving every single sin she had done. Relieving the guilt and agony. The agony of killing her own son when she had been alive.
After a minute or two, the sinner finally stood open mouthed, gaping. Her soul and spirit had finally crumbled at last. Her body then turned into sand, slipping through the beast's fingers. All that was left was the white piece of clothing.
The beast then put on the white clothing. Satisfied, she had decided it was time to do her job. She roared once more, making every sinner cower. "WHO DARES AWAKEN MY SLUMBER!" she screamed in a deep, demonic voice. Her wings shot out, and then she crashed through. She flew through every single layer of hell, leaving behind the core.
She was ignited by fury and rage. The only emotions she could feel. But she had a purpose. A reason for existing. Or else there would be no reason she would've been made at all.
Finally, she shot through the last layer of hell. The outer core. She roared and screeched. "SINNERS! VILE! SCUM! SUFFER ONCE MORE!" The sinners cried out in agony. Every single one of them. This was much more than what the Kushanada had put them through. The pain they felt was spreading through out their very bodies. Taking over their mind.

She flapped her wings, glaring at the sinners from above. The sinners below were crying. Crying for what they had done. Even those that had no feelings of guilt were crying now.
She chuckled as she looked at them. Obviously satisfied now, she turned around. Looking at the sky with a frown, she held up her hand. Red crimson lighting shot down, striking it.
When the smoke cleared, in her hand was a sword. It had a black hilt with a red sheath. Negative energy was all that poured from the cursed blade. Clucking her tongue, she lifted her tail and struck at the air. Not blindly, no. She was making a portal to the real world.

Finally, she stopped and the small little square she had marked began to shine. Once the small square in the sky crumbled, leaving an open portal she took one last glance at the sinners. She roared, "SCUM MUST NOT ESCAPE. SCUM MUST BE PUNISHED." After that, she finally walked through the portal. As she did, two black broken chains appeared on her wrists. She looked at them with a frown. "No matter how broken they appear, I am and always will be hellbound."
