Sitri had been dead asleep when she heard the strange noise at the glass. No demons dared trespass the castle of Hell. She blinked once and looked towards the window, her demons sight sharp in the dark.

She was shocked and overjoyed when she immediately recognized the faces of her two younger half brothers. She threw open the window, dragging the two inside before any guards would see them and alert the King.

She embraced the pair tightly but her joy instantly turned to worry.

"What are you doing here? I told you never to come back!" She cried.

Sebastian crooked a brow, "Yes you made that quite clear sister.." He states, his voice heavy with sadness and betrayal. "We're not here for a social call."

Sitri smoothed a lock of her hair down, her hair still very much in a disheveled bed head state.

"Then what brings you back to Hell?" She wondered, "you could have gotten caught!"

Sebastian sighed. "It's father. He keeps finding us. He wants us gone. We can't hide and run forever."

"But he promised.."

"Look" interjected the youngest, Stolas silent until now "when has father kept his word?"

The three considered this.

"I'll talk to father.." Sitri faltered.

"No. He won't stop trying to find us. We have to kill him first" Stolas said firmly. Sebastian nodded in agreement.

"We need your help. Together we can overthrow Lucifer. And you can keep your throne. Except now you won't have father dictating your choices. Please sister. This is the only way."

Sitri was not her fathers number one fan but she still felt a tinge of loyalty to her own blood. Not to mention going against Lucifer would a great feat in itself, being the second most powerful celestial being under God. While they where born of him and with great powers, Lucifer had the benefit of many years and experience as well as a cunning mind coupled with terrifying power made him a foe unlike any she'd ever faced.

"Just.. give me until the morning to think about it"

Her brothers seemed disappointed but agreed.

"I can hide you in my closet, it's almost as big as a room and no one else goes in there."

She made up a bed inside the closet and as they settled down to sleep she thought about thier request. Killing her father.

She couldn't deny what her brothers said was true. Although Lucifer had made her pay the ultimate price to keep her brothers alive, he went back in his word and now wanted to get rid of his failures. Her own dear brothers who she basically raised herself.

She thought about how he fathered them all and his treatment of her and decided she had no sense of loyalty for the demon after all. He was never their father in anything but a sperm donator. In the morning she would tell them her decision.

The next morning the plans to take over hell began. For months she hid them and during the day when most demons where away or sleeping they would practice honing thier powers.

Finally they felt ready enough and had gathered up the courage to confront their father in a battle that would shake the underworld to its core.

Each dressed carefully for the battle to come. Sebastian slicked back his short black hair. Usually his wings where hidden but today they where out in full glory. Huge feathery white wings with the tips of the darkest black. His eyes where the same color as his sisters and he simply wore a black suit, something he was most comfortable in. However, under the suit he wore a thin layer of magical spells, drawn onto his skin with dark fairy ink. To his back he strapped a sword. To the rest, he relied on his magic.

He didn't look intimidating he acknowledged but as long as he could survive and take down his father then everything is worth it. He was as ready as he could ever be.

Siri's dress was made of thousands of dragon scales which where very resilient against both magic and physical attacks. It was a deep violet with flashes of indigo and maroon. The neck was and back where cut into deep v's, sloping below her wings so they could be free. The skirt was cut short in a slanted pattern and belted together with a belt with 3 sheathes for a sword, a dagger and a small set of throwing knives. Her boots where armored and the same color as the dress, continuing halfway up her calf.

"I guess I'm ready" Sitri thought to herself, her hand resting lightly on the swords hilt. She started to wonder if it would be that very sword that.. She shook her head. They've already made it this far, she needed to just focus and do what she was supposed too.

Stolas pushed his shaggy black hair out of his face. Being half demon, his body aged much slower and at the tender age of 16 he was about to start a battle with his own father. His worried mismatched eyes gazed out at him, green and violet. He was shorter than his siblings, reaching up to the middle of his brothers chest and Sitris chin. However he made up for it in genius, although they often counted on his brains for a tactical advantage, Lucifer was quite sharp himself and had centuries more experience.

He began suiting up in armor made in demons fire, fireproof and almost indestructible. It was pitch black, each piece clinking into place. He had to protect himself the most being the most vulnerable as part human. Once dressed it gave him a few inches giving him the impression of being slightly taller which he definitely enjoyed. The chest plate had a purple crest on it, his family's crest. It stood for power and that is what he needed. The suit was a gleaming masterpiece, an intimidating metal soldier.

Finally they where ready, there was no backing down now as they would likely get caught and killed or tortured for treason.

The found their father in the courtyard, about to ascend to earth to wreck his chaos. He saw them, decked out in thier battle gear and changed his plans.

At first their father laughed, a deep rumble that shook the ground. "You dare betray me?! Kneel!" He thought to intimidate them but they stood thier ground.

Sebastian stretched out his half angel wings and declared "No!" before hurling a ball of light towards his father, catching his shoulder.

Lucifer smirked "Was that all you had?" He flicks his wrist towards his son, sending an invisible blade towards him in the blink of an eye, magically sharpened to even be able to kill an immortal.

Stolas knew his tricks and jumped in front of the spell and throwing out his forearm. His armor deflected it and sent it back towards his father, cutting a small cut in his cheek.

Lucifer bellowed, enraged. Sitri jumped into action and threw her 3 throwing knives straight into his gaping mouth. With a snarl he breathed out fire and melted the blades before they reached him, his flame even melting the magic imbued within.

"I'm so disappointed in you daughter. These half bloods I understand but you are to be Queen. Such a waste. Just like your mother" He hissed.

"Have you ever considered that mother let herself be summoned so she could escape from you?" Sitri hissed back "We are done with you. I will still be Queen but you will not be there!!"

She flew up, her wings stretched wide in midair shimmering with undertones of purple. Her eyes flashed deep indigo as she raised her arms and with a single flap of her wings she gathed all her power and hurtled it towards him with a huge rush of wind, knoking him to the side and slightly stunning the great King.

Sebastian followed lead, his power a blinding white ball of energy that hit his other side. Stolas had planned this and when the king was blinded from the two blows he struck with his sword and muttering a magic spell to strengthen his blow and sharpen his sword he struck the king down.

Sitri stepped close to Lucifer with her sword. "It's over." She poised her own sword over his heart, to make sure it never beat again.

"Not quite" Lucifer's eyes snapped open and he flung her into the wall hundreds of feet away. He grabbed Stolas and tried to bite but he couldn't get through the armor so he began to squeeze. "Even a demon can't survive after exploding" he laughed

"NO!!" Sebastian cried. Stolas had been there with him all that lonely time on earth and he was not about to lose him now to his father. Drawing his own sword he darted towards his father who now had grown over 50 feet tall. Charging with all his might he went for his heart, only to be knocked aside by a single finger as his father played with him as his brother's organs squeezed.

Sitri however was not down for the count. She took advantage of the diversion and went behind Lucifer and flew up to stolas.

"I need your power" Sitri said urgently, knowing the boy was no longer able to fight. He would one day be a force to reckon with but for now he was still only a 16 year old boy.

"No..t much use to me now" he whispered, as snarky as ever, red very human blood dripping down his mouth. She drew him near, her lips mere inches from his and she breathed in. His power came in a rush filling her like caffeine. She lifted the sword and with one swift cut she cut Lucifer's hand off, catching Stolas as he fell to the ground, unconscious. She flew him off to a safe distance and gave him a healing spell. He would be fine to recover on his own.

She rushed back to the battle where her father met her with a black void she immediately started being sucked into. She flapped her wings and strained away but it kept pulling her.

"Help!" Sebastian was closer to the hole than she was and barely clinging onto a stalagmite protruding from almost everywhere in hell.

There was no other chance, she would have to cancel his magic.

She stopped struggling and faced it. In her hands grew a fireball of black and purple flames, it became the size of the hole and then bigger and even her fathers eyes widened as she threw it towards his void, it crashed into it and exploded.

Sebastian was sent flying but caught himself with his wings. The explosion and knocked her father back quite a distance and they cautiously approached. All she did was cancel one spell, the war was not over.

"I'm almost impressed" her father grunted, rising to his feet, his handless arm clutched against his body.

"I would think you'd be a little more than impressed when you only have one hand" Sitri taunted, gathering energy for the next attack.

"I don't need any hands to finish you ungrateful brat!!" Lucifer roared. His next attack leveled the ground creating a huge hole where she had just been. Lightning fast she lept into air, narrowly avoiding the following repercussions. She weaved in and out, lashing out at his body with her sword as Sebastian helped with his own, flooding thier swords with every spell they could imagine of pain and destruction.

"You'll hack at me with toothpicks? You won't hardly make it challenging" Lucifer grinned, blood running down his body but many of the cuts where already healing.

Delighted to oblige, Sitri flew at him in a ball of black energy, she hit him, crackling with dark electricity. His back straightened and his eyes rolled back as his entire body jolted back.

His head snapped back and his eyes gleamed black as he charged them, he slammed them both the the ground repeatedly. "I will make you pay a thousand fold for the pain you've caused me today" He threw them into the wall, creating impressions. He opened his one hand it changed into a deadly claw, ready to shred them apart. They where stunned and couldn't move.

"I would say remember this moment, but by tomorrow it won't matter anyways" Lucifer laughed cruely. Sitri shook her head. They couldn't die here. What was all this for then? She struggled and tried to clear her mind. She just needed a moment. She was at a disadvantage still because of his pure size. She did not ever practice becoming a giant. She hit him with a few explosions that almost seemed to bounce off of him. Sebastian stirred beside her and they tried to get a short distance from thier giant foe.

"Still trying?" He snarled. He slammed his hands into the ground, causing the ground to rip upward in a huge earthquake wave. They where knocked but had managed to fly a couple feet up before the debrees hit to escape the brunt of the damage.

Sebastian weaved around him, flying in and out and dealing as many powerful blows to his fathers weak spots as possible. Thier father was slowly becoming tired out. They where also beaten and tired but they still had hope.

In the air Sitri made spears of black flame which she sent hurtling towards his vital organs but Lucifer dispensed her magic with his arm. However she did notice his arm was badly burned despite him trying to hide it. Lucifer roared in anger. His attacks grew more wild but also more uncoordinated and unfocused.

"I still can't do this alone, we have to do it together" Sitri declared. She was fast running out of stolas's power. "Together we are demon, angel, and, human and that will be enough to pierce him through. We have to do it now while he's still weakened."

Stolas had done his research about the 3 keys and while he didn't know how or want too how to activate them fully. But he did know how they could borrow their power because it was thier own power and together they where unstoppable. He had indulged this to Sitri before she had left him to heal safely.

Sebastian nodded, his suit now in shreds, exposing his skin glistening with sweat and blood. The writing still swirled across his chest and abs but the protective benefits where nearly gone. He had to rely on his own toughness and ability to cope.

Sitri stretched her hand out to him and he grasped it firmly. Together thier powers began to glow, a fire mixed with green and purple with white running through it. They charged towards him, thier powers growing more intense as they drew closer to thier father, the force of thier emotions and powers a sight to behold. At the last moment the two pulled off and the massive beam of energy thier power created slammed into him stronger than a cannon.

With that final blow, thier power exploded right through the King of Hells chest. For a moment Luifer stood frozen in disbelief, his mouth hanging open as he was about to speak but before he had the chance his entire body exploded into ashes and sparks before fading away entirely. The King was gone.

In victory, Sitri and Sebastian stumbled to find thier younger brother where she had left him and the siblings hugged each other. Although weakened and exhausted, they felt almost free with thier father not looming over them anymore. They had done it.

"I guess this means I'm Queen now" Sitri started, already back to real life, her shoulders already drooped from the responsiblity. They hardly ever stopped to think of what would come next. Was she even ready for this? She had helped to protect her brothers and now she is to take the throne many years ahead of schedule. Maybe she didn't even want to be the Queen of Hell. What if she was to become her father? Who is she supposed to be?

"I'm sure you'll do great! We'll help spread the word of the Queen that vanquished the King!" Her brothers assured her, thier focus more on wanting to celebrate thier victory and spread thier news.

"But that's not why I was worried.." She murmered under her breath.

After celebrating thier victory, the brothers soon left to spread word of the new ruler and the demise of the King. They would be back in a few days time. Within a few days she was to be Queen. There was nothing else to do but focus on the next few days. She turned to go back into the castle.. no. Her castle. She had better start getting ready for her coronation.
