Gate: Thus Britannia Liberated There!

Summary: The checkmate was played and the king has won. The White Emperor of Britannia decides to rule the world as it benevolent leader. A more kinder and peaceful world, yet, one world isn't enough. For where there are injustices, there is salvation. Post R2 AU.

A/N: I'm following the canon info from the manga and novel. That why the beginning may seem odd and massive spoilers to anyone only watching the anime.

Spoilers Warning

Because Hardy opened the Gate which was only a small doorway at the time. The Empire DID send SCOUTS ahead of time. The large Gate we see was in anime and the manga was after enough scouting missions, kidnappings, and manipulation via the Empire magicians to enlarge the Gate to fit the rest of the army.

I also know how brutal the Gate fanfic fandom can be...*take deep breath*...LET DO THIS!

*Granted, it justify when it short, overly unrealistic, or in...script format. Violating the rules and dammit I feel like Critics United now.

Chapter 1

Normal PoV

Hardy Realm

"Hardy, I presume?",A young woman with black through pink hair approach Hardy underground cave domain. The goddess of the underworld set on her gold throne, embellish with rubies, sapphire, and other subterranean minerals.

"Strange? I sense divinity coming off of you, but, you're not a Goddess", the Goddess of the underworld questions as she then licks her lips,"Then again with a body like yours. It telling me otherwise."

"Sorry for not introducing myself", She ignored the perverse comment with a passive face,"I'm the Dimensional Supervisor to the world you're about to open a Gate into."

Hardy smiled and leaned forward,"Oh really? What are you going to tell me? Don't do it? It going to enrage the deities on the other side? It's rather boring being a deity you know."

"As a matter of fact", The Dimensional Supervisor spoke,"I don't care because I know how this will play out. It will be a shock if something off script happens."

"Then you just came here to tell me that?",the Goddess raise a brow.

"The reason is because the moment a connection between time and space is made. I'll know, C-world will know, and then all the immortals connected will know", She answers bluntly,"For eons, I seen the Gate open to one world and the next. Rather it here or an alternate reality. It came to Earth multiple time during the early stage of human civilization. But if you open the Gate now, it isn't going to end well."

"Oh, DS, Can I call you DS?",Hardy asked and received a nod,"That just part of the fun. Thus far, every time a Gate is open. The result is the same, a species enter, make peace or fight. Neither side really changes much and there is no technological or social progress."

"Open the Gate to another world", DS shook her head,"I only came because I sense the initial disruption."

"I don't want to because it took forever to find a living world with enough sentient life that wouldn't conflict biologically with each other. None of the Gods could open the Gate under an ocean or the vacuum of space...no matter how fun it sounds."

"If you're so steadfast in this then I will allow you. But accept what will happen next, that arrogant smirk of yours going to disappear Hardy. C-World will claim no knowledge of such transgression and neither will the immortals, our Code Bearers, until it too late", DS walked away, her back turn to Hardy as her form slowly disappear,"Don't be surprised if you're brought down to the level of a lowly mortal Hardy and killed like one."

"I don't believe you, but I know you're looking forward to the interaction between our world DS."

"I guess you're right", the Supervisor finally disappeared back to her world.

The Golden Age Begins

2 Months after the final battle, The Emperor releases all his enemies from prison with a treaty resulting in all the world power temporarily being consolidated to him. The world leaders have to agree and for the next two years, he rebuild the world, help the hungry, and erase corruption and evil elements from the world. The people, regardless of nationality, worshiped him. It was he, who liberated the world.

In between those two years, he has married multiple women. The first being 1st Empress, Cecilia Corabelle. The shortly after 3rd Empress Kaguya Sumeragi and 2nd Empress Kallen Kozuki as a way to bring unity to Japan and the Black Knights.

Then in the final years, he got on live TV and reveal himself to be Zero. The world was shocked and baffled that the Man of Miracle and the White Emperor are the same voice, ideas, and person. The people protested especially in Japan and China, but in the end, the actions of Lelouch won out. Once he releases power back to the world leaders and sends the Damocles and all the FLEIJA's into the sun. No one resisted because the majority of their own people are siding with the Emperor. There are no longer any resistances because no one can survive the collected might of the world.

Unfortunately, on October 5, 2019, A.T.B, disaster strikes. A rogue faction of fanatics attempted to kill our benevolent Emperor. The end result was the Emperor becoming fatally wounded. Yet, like the man of miracles, he once was; His majesty left the hospital the very next day as if his bullet wounds means nothing to him. That when the final truth, his immortality, his commitment is revealed.

May he live a thousand years, Hail Immortal-Emperor Lelouch and glory to the world.

Ginza, Japan

March 2020 A.T.B

It was a normal morning in Ginza. A former ghetto, rebuild by the kindness of the Emperor. Everything was running peacefully in the new system created. Men and women hurry to work and children to schools. War was already a distant memory and the people look to the future.

Lately, There has been occasional missing person report and strange men wandering the alleyways at night. It was minuscule at the time as local authorities try to resolve the situation. There no need to involve Britannia. The foreign military presences in Japan cities were removed last month and even if both countries are on good terms. The people don't want foreign soldiers patrolling the streets like the days of old.

The law enforcement in downtime Ginza ramped up security once report that the second Empress, Kallen Kozuki, was visiting the city or in this case, view the recovery of Japan and to visit a former Zero squad member.

Kallen PoV

I still couldn't believe how quickly things rebuild. It has been only a year ago, only 3 out of every 4 people are fed. Now the city looks better than how it was before Britannia invaded.

I kept my disguise on with the elite royal agents keeping watch on me from various viewpoints. I'm amazed what a simple black wig and sunglasses can do as I walk effortlessly to the destination without anyone looking my way. As a added message of protection, their currently a Cerulean class airship hovering high in the sky with a squadron of knightmares and my 9th generation Guren prep and ready. It's not like Lelouch would send me out with only a handful of bodyguards. Even if their zero chance someone or some group will come after me!

He has been acting paranoia the last month. He kept saying a threat is coming but he just couldn't figure out what it is. CC even felt it and she's the more experienced immortal.

All I need is to find the last surviving Zero Squad member and catch up on old time.

Now, the OSI stated he heading to a Doujinshi Convention. So that where I'm heading.

I came at a crosswalk and a sense of foreboding overtakes me. It wasn't long until I look directly down the street at a marble gate. It was 5 block down and my first thought was,'What the hell?'

"Ma'am. It time to leave", One of the agents spoke into the Bluetooth in my ear.

"Wait, Let see what happen,"I then added,"What the status on my Knightmare?"

The moment of pause as he radio the airship to report that it ready to deploy at my very location was long enough for men and beast to march out of the gate. A lone horseman marches out making some sort of decree to the stunned and curious civilians.

What the hell is going on? Are those ogres and Romans?

"My Empress! You're husband personally request that you retreat!"

"Not-NO!",the sound of tributes and the roar of battle commence and the slaughter begin. Dragons-actual DRAGONS suddenly flew out the Gate with soldiers on their back.

Japanese were getting slaughter and I stood in place.

It was for a moment, I saw a flashback of Tokyo being bombed by Britannia bombers, soldiers going on a killing spree, and I just stood and watched as it burns.

No...It won't happen like last time.

"Deploy my Guren", My right-hand grips the key around my neck.

"But!"

"Deploy my F**KING GUREN NOW!",I roared.

"Yes, Ma'am. It only takes a minute."

"THE CIVILIAN DON"T HAVE A MINUTE!".I yelled again and waited as I help with directing those running away. The slaughter happening behind them. Calvary charges ahead impaling those on their spears. Dragons picking up the helpless civilian in its jaws. Archers firing a rain of arrows. Cars and people being swatted away by ogres and viciously torn apart by other humanoid creatures.

I don't care who they are, but you step on my country soil and spilled Japanese blood. I will show no mercy.

A/N: Sorry for the cliffhanger. But worth it when Kallen come down with the red death.

If you're familiar with my other fanfic. The thing I pride myself in is writing my own stories; I will have changes to canon or deviations. I also plan to have a longer chapter after a bit of Gate revisiting since it been months since I read the first chapter of the manga and longer when I saw the first episode. Then there getting a bit more knowledge on the military jargon because of that what I like about Gate.

Otherwise, Code Geass is my most knowledgeable field and even I will try to smooth out the faults in the GATE series. Somewhere along the line of the upper tier writing of Gate: World at War in term of realistic reactions and actions.

It will take some time for me to explain the whole Lelouch become Emperor of the world storyline. I just abridged it heavily in this chapter and will reveal more details. I can't guarantee a speedy update because of my priority to my other fanfics. Hopefully not being the authors with a shit ton of uncompleted fanfics.

Please read and review and be helpful. I know my grammar crap so go on right ahead.
