"The Great Red" Dragon

Code Geass: Demon Emperor

Chapter 1 : The Day a New Demon was Born

"Yes, I have..."

"Destroyed the world"

"And created..."

"Anew."

That was his final words as he took his last breath and died in front of his sister, Nunnaly Vi Britannia.

This is mark the end of Lelouch Vi Britannia, the 99th Emperor of Britannia reign or known as The Demon Emperor reign.

He has no regret as he embrace his death. Because in his short life, Lelouch has done more than anyone could hope to accomplish or dream off. He has fulfilled all of his goal and his promise to his sister, to make a gentle world.

Even with the knowledge that history will record him as the most evil man in the history of humankind as the payment to realize his promise to his sister. Forever he will be known as the Demon Emperor, his name will be spoken for centuries as the source of fear and hatred. Nevertheless, to him, that is a small price to pay for a better future.

The world will never know the sacrifice he made but select few.

To think this all started with a simple promise from a brother to his little sister.

However, even if he does not feel any regret, he feels guilty for two things.

The first one, he lied to his sister when he promised to never lie to her. This is the first time he ever lie to her but this is for the best. He hopes his sister will understand this.

The second one, he broke the promise that he made with C.C but he known that C.C understood why he done it. After all, she was the first one that supported his plan. He just hopes someday there will be someone who will release her from her curse. It`s too bad that someone is not him.

"Le…"

'Huh?'

"Lelouch…"

He heard a small and soft voice calling his name. However, that cannot be true as he was already dead. Though he noted that the voice seem familiar.

"Lelouch, please open your eyes…"

The voice asked, leaving him confused.

"You are not dead yet…"

….

….

For a brief second, all the thought in his head disappear, leaving a dreaded feeling inside of him. If by some reason he is still alive then his plan is doomed to fail because his plan, the Zero Requiem will be only success if he died.

However, he doesn't hear other sound except the voice who asked him to open his eyes. Surely…

"But you are not alive either"

The voice informed him. This left him speechless as he is become more confused.

Slowly he opened his eyes.

What he saw left him stupefied.

He was floating in the middle of space and right before his eyes there was a planet, Jupiter to be exact. However, after he calmed himself he realized that was not Jupiter but something that he saw before when he was in C world. It was the collective human unconsciousness or the God itself. Instantly his mind makes a hundred of theories why he ends here. However, there is only one that plausible.

"It cannot be…" Lelouch said in disbelief.

"The God is the collective sub consciousness of all humans' beings metempsychosis into the World of C" The same small and soft said from behind him.

Lelouch immediately turned back to the source of the voice.

"And the world of C is the will of mankind…"

Lelouch eyes widen as he saw who is talking to him.

"Wh…." Lelouch tried to speak but the words are choked in his throat.

"Hello Lelouch, long time no see"

Lelouch feel his eyes become wet. Right in front of him, there was someone who he never dream or hope to meet again.

Someone that he thought he lost forever.

Someone that died by his own hands.

Someone that hold special place in his heart.

However, right now, against all odds, she was in front of him.

There is no scorn or hate on her face but a small warm gentle smile.

Lelouch could not hold out anymore.

A lone tear fall down his cheek as he whisper her name, "Euphi…"

(Skip)

"I see…" Lelouch nodded in understanding with Euphemia in front of him.

After he calmed himself, Euphemia explained the reason he was here. Truth to be told he is already got the gist of it before Euphemia explanation. Therefore, he was not too surprised.

In his reign as Demon Emperor, many people died from his order and because of that. They hated him and wished him to burn in hell or to suffer forever, be it unconsciously or consciously. With the C world as the will of humankind and the God is the collective sub consciousness of all humans' beings. It's no wonder that he was rejected to join them. After all, who want to join conscious with someone who knows as the most evil person on earth? In addition, the world of C has decided his punishment for what he has done.

"So this is the true price that I must pay…" Lelouch asked Euphemia who nodded her head and smile sadly at him.

"…."

"…."

They fall into awkward silent.

"Honestly, I kind of expected that when I realize I was in C world" Lelouch said suddenly.

Euphemia just stared Lelouch in disbelief before a look of understanding dawned on her face. After all, Lelouch is one of the brightest people in royal family rivaled only by Schneizel. Therefore, it is not a surprise if he expected it even before she told him the truth.

"I see" Euphemia said sadly as she knew that no one deserve this kind of ending especially Lelouch. After all the sacrifice, that Lelouch made so the world became a better place. He deserved to be able rest in peace but instead he got something worse than death.

"For a better future and to break the chain of hatred I became the source of hatred, the symbol of evil and a demon" Lelouch said out loud with a bitter tone, "I know someone like me doesn't deserve salvation or forgiveness. Still…"

Lelouch turned and stared Euphemia directly into her eyes. Euphemia resisted the urge to flinch as she looks into Lelouch eyes. His eyes were so tired and old beyond his ages. The pain and suffering that Lelouch has gone through reflected clearly on his eyes. Euphemia felt her heart shattered at the defeated look of Lelouch. This was not the Lelouch that he known after all.

"I have a small hope that maybe in death I will find it but instead of salvation or forgiveness…" Lelouch let out a small defeated smile, "I find damnation instead"

'A perfect ending for a demon like me…' Lelouch added in his mind.

His mind understand this is the most likely outcome for his action but his heart not. The sheer of despair that he fell right now when he learn that his last hope for peace, to atone his sins was forever rejected is too overwhelming even for him. He will never be at peace. He will be forever tormented by all things that he has done. However, is that matter?

After all, he is a demon in human flesh. His actions prove it.

'A demon….' Lelouch thought as a dark smirk formed on his face.

"Do you regret it?" Euphemia asked uneasy as she saw the dark smirk that started to form on Lelouch face. She could not help to shiver a little. Lelouch is on the verge of losing himself and she cannot let that happen. She knows that he was tired but to lose himself this quickly. No, she will not let it happen. She will not lose him for a second time and for that reason, she was here.

Lelouch blinked at the sudden question before he averted his eyes from Euphemia and look up.

'Did I regret it…?' Lelouch thought as he remembered all of things that he have done.

Truly, he has done a great work to make himself as the enemy of the world. People view him as the most evil man and a demon. The hatred of the world is focused solely on him alone. However, at the end he accomplished his goals and fulfilled his promise.

"No, I`m not" Lelouch answered firmly without wavering one bit, "It's for a better future… a world that Nunnaly wished"

Lelouch look back to Euphemia and let out a smile, a true smile.

Euphemia became relaxed as she saw this. It seems deep down Lelouch is still the same Lelouch that she knows. Still she must make sure of it. She must make Lelouch remember.

"Even if you are rejected from this world…. Forever you will be trapped in this void?" Euphemia asked, her tone full of sorrow, "Cursed with half existence… not dead and yet not alive? Is it worth?"

Lelouch just kept smiling as he looks down at his chest that has no wound on it.

'Is it worth?' He asked himself, 'Yes'

"Yes… I do not regret it. This is the path that I choose and regardless the consequence I must see it to the end…." Lelouch said as he looks back at Euphemia.

'Thank you Euphemia for remind me of this…' Lelouch thought as he realizes who close that he lose himself. However, Euphemia made him to regain back his conviction. The world of C may deny him but he won't lose himself.

The punishment that the world of C decided beside that he could not join the collective conscious is that he will forever trapped in here, in this void, which located between the world of C and the living world. He has no hope for return or contacts anyone even C.C.

He does not know if he must curse the God or not for this punishment but he is grateful because before the God condemn him, he can see Euphemia for one last time.

Deep inside his heart Lelouch knows that the real reason Euphemia here is because someone needs to tell him his punishment. However, he prefers to think that the God granted his last wish to meet Euphemia. Though, it's only a matter of time before Euphemia will go and leave him alone here and the start of his punishment.

Euphemia just smiled sadly at Lelouch.

"You are…" Euphemia stopped before she finished her sentence and shook her head.

"Lelouch, you don't deserve this…." She whispered softly as she looks up at the collective sub consciousness of humankind, "We won't let it happen…"

"We?" Lelouch repeated as he looks at Euphemia.

"Yes, we…"

For a briefest moment, Lelouch can see the image of Shirley behind Euphemia.

"What…." Before Lelouch could finish his question, Euphemia put her finger on his lips.

"It`s true that many people want you to suffer but…." Euphemia paused as she pull pout her finger from Lelouch lips, "There are other who doesn't wish for that…"

"What do you mean?"

"Those who know your true plan…" Euphemia paused as a low humming sound could be heard, "Doesn't wish this happening to you"

Lelouch just stared at Euphemia face in confusion when a look of revelation dawned on his face.

"It cannot be…" Lelouch trailed off, "Are you planning to defy the will of the world of C, the will of mankind itself?"

"Yes" Euphemia answered firmly.

"But how can you do that? One person wishes against the will of mankind…." Lelouch asked in disbelief. Euphemia is trying to do the same thing that he has done when he stopped his father and mother plan. Though he doubted what Euphemia trying to do is going to work as the only reason why he could done that before because his absolute obedience geass and Euphemia does not have it.

Euphemia smiled sweetly, "It's not a wish of one person Lelouch…."

As soon as Euphemia said that the image of C.C, Shirley, Kallen, Nunnaly, Suzaku, etc. appeared behind her.

"Though, you are right. We cannot defy the will of mankind but we can alter it" Euphemia said as the humming sound become more louder than before.

"We will send you to other world, a new world without God…." Euphemia take a step forward, "Or Satan itself, so you will not be judged from your past sin"

"New world…" Lelouch repeated in disbelief. This whole idea of the completely new world is foreign to him but….

"You should know it already or feel it…" Euphemia stated, voicing Lelouch thought.

True, he already knows it or perhaps feels it when he was in the world of C for the first time. Nevertheless, it was a fleeting feeling and he is not too sure about it.

"Think this as a second chance for you Lelouch" Euphemia said as she raised her hand and touched Lelouch cheek gently.

Lelouch feel himself melting under Euphemia warm hand.

"However, you will lose your power, your geass of absolute obedience as geass can only work in this world only…" Euphemia told Lelouch softly as she draws close to him.

"What?" Lelouch said aloud. Why he will lose his Geass? If he loses his Geass then how can he survive in the new world? True to be told he was happy when Euphemia said he would get a second chance but he should know better. There is nothing in the world that has no prize.

Sensing Lelouch confusion Euphemia decide to explain it, "Because the power of Geass is something that born from this world god or to be accurate the collection of subconscious and…"

"In the new world there is no God or a different kind of God…." Lelouch continued as the humming sound became more louder.

Euphemia just smiled how fast Lelouch came to conclusion. He will do just fine in the new world.

"This is our gift for everything you have done…" Euphemia said softly as she guided Lelouch head and kissed him softly on his lips. The humming sound suddenly stopped. There is only silent.

"Euphi…" Lelouch muttered, as he looks deep inside her eyes.

"Goodbye Lelouch…." Euphemia said as she let him go.

"Wh…" That snapped his attention as he realize that his body disintegrate into particles of light, just like what happened to his father and mother.

"Euphi! Wait!" Lelouch yelled as he brings his hand out to Euphemia.

"I forgive you"

That stopped Lelouch on his track as his breath hitched and his chest constrained.

"I never hate you for my death"

His shoulder feel light as a huge burden have been lifted.

"So, please don't blame yourself anymore…"

Lelouch feel his eyes become blurry and wet from the tears that forming on his eyes.

"You deserve to be happy"

Tears were flowing down freely from his cheek.

"Sayonara my…."

Lelouch could not hear Euphemia voice anymore as he completely disintegrated into particles of light. However, just before he disintegrated he saw the image of smiling Euphemia with Shirley behind her.

….

….

Euphemia just smiled sadly, as he saw Lelouch completely gone from this world into another. Her heart is hurt but she knows this is for the best.

"Are you sure it's okay?" Euphemia asked aloud, "Not to meet him for the last time?"

From behind her, another figure materialized.

"Yes, I`m sure"

Euphemia just nodded in understanding. He does not need to look back at the figure, as she knows who it is.

"I hope you don't regret it Shirley" Euphemia said as she look down at her feet which slowly disintegrating into particles of light.

"No, I don't…." Shirley said as she walked beside Euphemia. She is also disintegrating into particles of light, "This is for the best"

Euphemia nodded as she accepted Shirley answer.

"So this is it?" Shirley asked as she looks at Euphemia.

"Yes" Euphemia replied.

The two of them just look back at the space Lelouch once stood.

The true is she has not told Lelouch the whole truth. There is another price beside the loss of Lelouch power for defying the will of humankind. If Lelouch know this, he would not accept the second chance that she and Shirley gave to him. He was too kind after all and it will only make his burden become heavier. Therefore, she does not tell Lelouch about it.

The price for those who against the will of humankind to save the demon from enteral damnation is ceases to exist. They will not be reincarnate or join the collective conscious back. They will be erased from this world.

She and Shirley know about this. However, it does not deter them to save their loved ones.

"It's nice to meet you Euphi…." Shirley said as she smile to Euphemia before completely disintegrate.

"Yes, it's nice to meet you Shirley…" Euphemia replied one last time before disintegrate.

With that, the existences named Euphemia li Britannia and Shirley Fenette is erased from the World of C. Lelouch will never knew the sacrifice of the woman that he love made and that's for the best.

-Dimension Gap-

Inside the distorted place between dimensions there is a huge red dragon resting on a small ground that floating in the space. This place was the Dimension Gap, located between dimension and that dragon is The Great Red or known as the Apocalypse Dragon, the True Red Dragon Emperor God, True Dragon, the Dragon of Dragons, and one of the two divine dragons. A dragon that have power even more than God and Satan and born from "Illusions" of dreams and represents Fantasy.

The Great Red stirred from his resting place. He feels something passing his domain, the dimension gap. Which is something unusual as no one should able done that but a select few. Moreover, this select few knew better to not come to his domain.

This made the Great Red, the most powerful Dragon in existence feel a feeling that he doesn't know still exist in him.

Curiosity.

He is after all has live since the time of creation. Nothing has gained his attention since the battle between Satan and God that ended with the death of the two of them. Nowadays he spends his day sleeping as it has become dull lately.

So to say he is happy is an understatement of the centuries.

"Let's see…" He whispered as he willed his power to catch whatever that passing his domain.

A ball of light materialized in front of him and imagined his surprise when he saw unconscious human inside it.

"Well, well, what a surprise…" He chuckled in amusement.

"A human, here, in the Dimension Gap" He studied the human closely and from closer inspection the human before him is male. The man wear strange clothing, not that he understands a thing about fashion. After all, he is a dragon and he doesn't need clothes. However, he found something odd about the man before him.

Therefore, he decided to enter the man mind. He is after all an existence with the power of dreams and can descend into people's thoughts and turn dreams into reality. So entering the man mind is an easy thing to do.

As he entered the man mind, he found his way to the man memories and watched it. When he finished, he let out a small grumble before became a full blow laugh.

"Interesting….a human from another world!" He roared loud.

The man before him was named Lelouch Vi Britannia and he came from another world, a different universe than his. However, what gained his attention is the fact that this man, Lelouch is an Emperor who has conquered the world to only die to bring peace to the world.

"How noble…." He said and there was no mockery in his words.

"Also what an interesting view you have there…" He muttered in amusement.

"If the king does not lead, how can he expect his subordinates to follow?"

"The only ones who should kill, are those who are prepared to be killed."

"I see, then I... shall become evil to conquer an evil larger still!"

He quoted three Lelouch words that he found the most interesting. He cannot help to feel a certain degree of respect for this man, no, Lelouch. What Lelouch have done is something that could not be ever compared to anything else.

Their meeting, perhaps fate is the one that bring them together.

"Perhaps…" He trailed off as he studied Lelouch.

His world right now was throw into chaos because the absent of The God and Satan. However, not many know of this fact. Still, the future seem dark to him. Maybe, just maybe Lelouch can put an end to this chaos and bring balance or a new order. After all, Lelouch has done it before so why he cannot do it again?

"Yes, this will do" He muttered as he came to decision.

"Lelouch Vi Britannia, you are the first human that I come to respect and acknowledge in millennia" He proclaimed to the unconscious Lelouch, "And for that I will give you a gift…"

As soon as he said that, Lelouch body disintegrated leaving his soul only.

For the first time in millennia, the Great Red is shocked. He knows someone like Lelouch will not have normal soul like other human but this, this leave him speechless. Lelouch soul, not only it is big but also shines brightly than any soul that the Great Red ever sees before. Furthermore, instead the usual gold, silver, black or white one the color of Lelouch soul is purple, no, amethyst to be correct, a beautiful amethyst. Now, he sure that Lelouch is the one can put an end to this chaos. If not Lelouch, no one can.

"This body will do…" The Great Red said to himself as he has the perfect body for Lelouch soul, a great body for a great soul.

In instant, another body identically to Lelouch but younger appeared beside Lelouch soul.

He watched as Lelouch soul entered the body and gave a satisfied smile.

However, another thought appeared in his mind. It won't do if he sends Lelouch to human world. It will counter productive and it will take a long time before Lelouch realize his new potential. Still, he cannot send Lelouch to hell or underworld. It will only bring Lelouch unnecessary danger if he does that. Not to mention the remaining of the 72 Pillars will try to…

The Great Red let a smirk as he remembered something about one of the 72 Pillars.

"Yes, it will do… "

(Skip)

-Underworld-

-Dantalion Mansion-

Duke Dantalion put down the book that he had reading to the table as he sighed for a million time.

Once again, for the million times he is lamenting his clan situation. The once mighty Dantalion clans that have the most prestige and power have been reduced into this, a pathetic clan that has lost its status. On the positive side, he was not the only one that lost it. From the 72 Clan, only 34 survived the Great War. However, actually, there is more than 34 houses that survived but just like him, they lost their status due various reason. In his case, the only one that still alive is only himself as the rest of his family is dead because the Great War and one cannot call itself a clan if there is only one person in that clan.

He could always marry and sire a child but that is out of option because he is old, old enough to be called great great grandfather by the current generation. He is after all one of the survivor of the Great War and the oldest devil in underworld.

To make things worse, he know that he have not much time left. It's only a matter of time before he will die and then the Dantalion will be forever lost because he has no heir. Well, he could always use the Evil Pieces that he got from Ajuka Beelzebub but he couldn't. not for the lack of trying in his part but he simply couldn't find someone that suitable. Call him picky but cannot let anyone to just waltz in and become a part of his clan.

At first, the requirements are to love book and smart, as Dantalion clan is a scholar clan that collect book. Which make his clan famous for their knowledge but he cannot find anyone like that. The youngster nowadays only care for power and forsake the past as they deem that unnecessary. To him that is something that he couldn't forgive, which the reason why he distancing himself from the current hell government.

Still, he couldn't let his clan to disappear away just like that. If things come to worse, he will just take anyone and hope for the best.

Duke Dantalion is surprised when his surrounding distorted and replaced with vast space. However, his confusion is short as a huge red dragon appeared. He knew who exactly that dragon is, The Great Red.

"Still searching for a worthy heir Duke Dantalion" The Great Red boomed.

"Great Red… then this is a dream?" Duke Dantalion as he finally knows where he is.

"Yes, sharp as ever…" The Great Read praised, "Truly your title as Dantalion The Mystic Archives of Dantalian is not just a name… "

"Thank you but it's been a long time" Duke Dantalion addressed the dragon with respect, "For what I owe this honor"

"It is and cut that out. We are friend after all" The Great Red said as his tone suggested that he is annoyed by Duke Dantalion greeting.

Duke Dantalion just let a small smile. He is after all the Great Red friend after all. However, no one knows this as it will only bring trouble.

"So what do you need Great Red?" The Duke asked as its unusual for The Great Red to come to his dream after all.

"I have a…proposal that you may find benefit both of us" The Great Red explained as Duke Dantalion raise his eyebrow.

"And that is…" Duke Dantalion urged the dragon to speak.

"This..." The Great Read materialized the unconscious Lelouch.

"Please explain…"

(Skip)

"I see" Duke Dantalion nodded his head as The Great Red finished his explanation.

'A human from other universe, that's so unreal even by devil standard but….' The Duke Thought as he studied Lelouch, 'If what Great Red said is true then I finally have find someone worthy'

"So what is your decision old friend?" The Great Red asked as he looks at Duke Dantalion face. He knows the duke will accept it, as there is no one else worthy but Lelouch. As Lelouch have the traits that the duke want in an heir.

"You already know the answer don't you?" The duke asked. With Lelouch as his heir not only that the Dantalion clan will continue to exist but will also prosper and regain back its glory.

"Yes, then I leave him to you" The Great Red said as he moved Lelouch who is floating to the Duke, "When you wake up you will find him near you"

The Duke nodded, "Still the problem he is a human so I must use the evil piece"

"You don't have to worry about it. I have modified his body a little" The Dragon reassured the Duke, "Though if you still want to use the evil piece, I won't forbid it"

"You have changed his body into a devil?" The Duke asked the dragon ridiculously. Lelouch must have impressed the Great Red greatly if he done that to him.

"That's a secret…." The Great Red answered, "Though I think that a normal evil piece won't be enough for him"

Now this gains the duke attention and makes him want to see what piece that Lelouch will get.

"Then, until we meet again" The Dragon said as their surrounding become distorted once more.

(Skip)

The Duke suddenly snapped his eyes open and look at his surroundings. He is in his library; he must fall asleep when he was reading before. Then the memory of his meeting with the Great Red hit him and he begins to search around him. Not far from his place there is a young man sleeping on the floor.

"So it's real" The Duke muttered as he stood up from his chair and walked to Lelouch.

As soon as he stands beside Lelouch, he snapped his finger and a set of evil piece appeared, floating in front of him.

"Let's see, what kind of piece that you will get"

At first, the Duke start from one pawn but it does not seem enough. Soon he tried two, three, four, five, six, seven, and finally eight but it's still not enough.

"Interesting… so you worth more than eight pawn" The duke muttered to himself. if eight pawn is still not enough then its futile to try Bishops and Knights as each worth only three pawn. Therefore, it leaves two Rooks or one Queen. A Rook is equal for five pawns and Queen is equal to nine pawns.

"A Queen or Two Rooks…" The Duke Wondered.

"Let's see the Queen first" The Duke decided but to his amusement, it's still not enough.

"Well, well then the Rooks" The Duke said but it's also not enough.

The Duke became speechless by this. Lelouch must be having a huge potential. Still this leaves him with the last option, the King.

"I don't think it will come to this…." The Duke said in disbelief as he grabbed the floating King piece and look at it.

Instead the usual crimson color, the color of the King piece is amethyst. Duke Dantalion knows why the piece is amethyst and it makes him hesitate for a second. This amethyst King piece is Mutation Piece and something beyond priceless or rare. You can get one Mutation Piece of Queen, Rook, Knight, Bishop or Pawn out of ten Devils but one Mutation Piece of King. That is something that could be said a miracle if you get one, as it was one out of million chances. The reason why he hides this from other as it will bring unnecessary conflict for this piece.

"I hope this is worth it…" The Duke decided as he put the King Piece and accepted.

Lelouch body glowed for a second and the next thing the Duke saw will be forever engraved into his memory.

"Impossible…."

Please Review

A/N: Another take what happened after Lelouch death, it have the same idea as my story Code Geass: The Power of The King but also different.
