Lelouch Lamperouge aka Zero has ready his plan to engage the battle against Britannia. The Black Knights made contact to every resistance in Japan to join them and their allies to liberate the country once and for all. Most of the members of Kyōto house decided to take shelter at Fuji for their safety so a girl named Kaguya Sumeragi decides to join Black Knights to see Zero. The Black Knights preparing their knightmares, weapons, and ammunitions to fight against the enemy alongside the allies. Kallen goes to Guren Type-02 as she activates to engage the enemy. Tamaki and the others went on their knightmares too for the battle. Ohgi was worried about Chigusa so he tried to call her but he don't need it since he know Henry agents have take her to safety so he went to focus on the mission.

In the ghetto, They riding on stolen G-1 base which it was Zero behind of it using a Geass. Behind BK G-1 base are the resistance group from every region to support Black Knights. They are determined to take back their country by following Zero commands. Zero was on the command center to see they going straight to Tokyo Settlement.

Zero: It seems like the britannians are busying on fighting against our allies. But what they don't know that it is a diversion so we can surprise attack on them.

C.C: And you sure a plan of yours will work?

Zero: Of course! I make plans so you can trust my strategy.

Area 11 Conference room

Britannian nobleman 1: The entire cities are uprising by Eleven insurgents.

Britannian nobleman 2: The honornary legion forces have turned against us.

Britannian nobleman 3: I can't believe they are so many of them at the southeast.

A 28-years-old man named Kanon Maldini, a subordinate of Prince Schneizel el Britannia, can't believe to see so many of enemies coming from southeast of Area 11. He said to His Highness.

Kanon: Your highness, that's not the only one in the southeast. There is alson another one at the west.

Alicia: What?!

The screen shows another navy forces coming from the west coast of Japan.

Calares: Who are they from?

Britannian nobleman 1: It can't be... I've seen them before. It's Middle East Federation navy force.

Bartley: What?!

Britannian nobleman 2: Liar! The MED was crushed by mighty power of Princess Cornelia. How can they able to rebuild the military.

Schneizel: Not only that, the others from southeast are from other Areas. But they able to liberate it and reconstruct the military force without viceroys knowing they already being attacked and not call for help. I'm starting to think that a man from broadcast is responsible of it.

Calares: Him?! Bah! He will see what happens to those who challenge the Holy Britannian Empire.

Bartley: Bur without Princess Cornelia and her knight Gilbert leading the battle, it would be catastrophic defeat.

Calares: I go! I'll lead the battle against uncivilized monkeys myself. I would like to see them humiliate for their foolish actions.

He stands up and walk out of the room to prepare his G-1 base for the battlefield.

Bartley: Your highness, would you like to join the battle as well?

Schneizel: No.

Bartley: Huh?

Schneizel: Let him be. He owns this Area so he will be responsibility to take action by his own hands. Speaking of it, Sub-Viceroy Alicia, have you called reinforcement from the homeland?

Alicia: Of course, your highness. They will be here in few minutes. We just need to hold on until they arrived.

Schneizel: Good. That'll help him to win this battle. Let's hope he'll get his victory against them. Also, order to protect this place immediately. Sent the Glaston knights to defend it.

Bartley: Yes, your highness!

He lean back the chair as be put his finger on his chin to think about new enemy leading them to fight against Area 11. He finds intriguing to a man from broadcast that he's kinda a revolutionary man and speak english as well. He don't know how he do it, but he can be sure that something is going on him. He'll find out soon as the Area 11 is becoming a war zone.

Kagoshima Settlement Coast

GDI IUSS aims the lasers at cannon towers and solar panels as ion satellites destroying them in each blasts. The Allied forces bombardment the britannian defense positions that tries to held them back. GDI sends out orca bombers to destroying britannian knightmare forces on defense positions.

Tom: Alright, listen up boys! We are entering the enemy territory to liberate Japan for freedom. Now, I want all of you to stay alive to keep fighting those britan assholes. Let me ask you something, do they own this world?

GDI soldiers: Hell no!

Tom: Do they own every territory they taking it?

GDI soldiers: Hell no!

Tom: Do you want to watch every men, women, and children get killed indiscriminately by Fascist Britannians?

GDI soldiers: Hell no!

Tom: Then what are we fighting for?

GDI soldiers: The GDI!

Tom: What are we fighting against?

GDI soldiers: Holy Britannian Empire!

Tom: Then let's kick their imperial asses!

The GDI soldiers shouted for battle cry as they going to kill every enemy on the battlefield.

Daichi: Sir, I am ready to liberate Japan, even it's different from this world it consider as my home.

Daniel: I like you saying like that. Hey, when this is over, we'll get some drinks.

Jacob: Same here!

Tom: Alright, alright, we'll get drinks after this liberation of Japan. Right now, let's focus on the battlefield.

Both hovercrafts and landing crafts came close to reach the shore they opens the metal door and everyone goes through the beach. LT. Tom and his others rushed through the beach as britannian bunkers and knightmares shooting them in the distance. The britannians manage to kill few of GDI and the allied forces as most of them have take cover or keep rushing through the enemy lines. Tom and the others firing at them in the distance. GDI rocket pitpulls rushes through sands and fires rockets to destroy enemy bunkers and then GDI talons and zone troopers destroys sutherlands to clear the path. They reaching to the behind enemy lines as they taking down britannian infantry and ground forces. Two GDI drop pods came down from the sky to deployed two GDI mammoth MKII as they destroying all of them. Britannian soldiers are terrified to see those kind of knightmares that they never encounter before so some just retreat while others stays and fight back only to be retaliated by GDI and the allied forces.

Black Knights G-1 base

Minami: Zero, I've got word that GDI and the allies have engaged battle at Kagoshima Settlement Coast. The britannians are getting beaten. I also report that GDI will join us in any minute.

Zero: We are almost reaching to Tokyo Settlement so now it's time to commence the attack. Kill new viceroy and this victory will be ours. Diethard, Have Tohdoh handle the front line. I'm leaving you in charge here.

Diethard: Yes, very well, Zero.

Zero and C.C are heading out when the door opens to see Kaguya Sumeragi came to see him, which is surprised to Zero.

Zero: You're Sumeragi's...

Kaguya: Thank goodness I made it in time! That was so mean of you, the way you headed off to the battle without me! I've been a huge fan of yours ever since your big debut! I was hoping that I'd finally get to talk to you. Wow, you're really tall, aren't you? Don't worry though, I'll catch up with you pretty soon!

Diethard: L-Lady Kaguya, I thought the heads of the Six houses remained in Fuji.

Kaguya: I followed after you! So I can watch my future husband fight.

Both C.C and Diethard just shocked to her words then Zero said to her.

Zero: Don't joke around.

Kaguya: Well, once you win this battle, you'll eventually need a wife, won't you? I mean, I know your identity is a big secret and all, but you're gonna need somebody as your public face, right?

Zero: Really? You believe we're going to win this battle?

Kaguya: Of course! I am the goddess of victory after all.

Zero: I'd be lucky to have you then. Unfortunately, I've already made a contract with the devil.

Kaguya: Huh?

Zero: I have no room in my life for deities right now.

Zero and C.C leaves the room leaving her shocked to her expression.

...

Dark Lancelot and Lancelot goes out of kodiak II to join the forces to defeat britannia forces. Sutherlands were busying on fighting GDI and allied forces when they're being attacked by Dark Lancelot and Lancelot.

Sutherland pilot: What the- Lancelot has joined with them?

Sutherland captain: Traitor! Shouldn't known to be a number. How foolish it was to let him join the military of britannia. Kill him and his ally!

Sutherlands rushed towards them for attack. Dark Lancelot fires assault rifle at 5 sutherlands in each rows. Lancelot pulls out a sword and slashes on every sutherland.

Suzaku: I can't believe I have to go against them. But I'm with Princess Euphemia and I must fight to defend her with my life!

He said. Dark Lancelot pulls out MRAP to destroys a sutherland, killing a captain inside a cockpit in one shot. Dark Lancelot place down a beacon on the ground and contact on comms.

He said through the comms. A drop pod came down to deploy offense crawler and went forward. The allied forces follows a crawler to Tokyo settlement. Dark Lancelot and Lancelot goes ahead to support them through the battle against britannian forces.

A sutherland equipped with bazooka fires back at allied forces when Iron Knight appears and stabs through the chest using a sword. Another sutherland came from behind when he was being destroyed by Grey Wolf at the left side.

George (on comms): Hey, bud! I see you handle this situation.

Michael (on comms): Yep.

He fires large size minigun at 4 sutherlands in each rows.

Michael (on comms): You know, if Nod did have an idea of making knightmare from our world it would be harder battle.

George (on comms): At least they didn't have that idea. Now let's move!

Both Grey Wolf and Iron Knight clashes through britannian ground forces in full attack. Iron Knight throws a large grenades to explode 2 APCs and britannian soldiers. Grey Wolf fires directly at the enemy in each rows using his large size carbine rifle. 2 GDI razorbacks came to support them by shooting down enemy infantry forces.

GDI reinforcement came to support them to defeat the remains of britannian forces.

...

Hawaii

On the sky, GDI firehawks and interceptors flew towards Hawaii where the navy and army base were ready to go Area 11 for reinforcement. Unfortunately, they don't have time to get there as GDI air forces have reached to the Hawaii.

GDI firehawk pilot: Alright, boys! We're gonna hit everything on imperial britannian bases and take over Hawaii. We will be like Imperial Japanese attack Pearl Harbor. So let's give them a surprise attack.

A squad of GDI firehawks flew towards britannian navy base and dropped the bombs on the ships. Britannian navy ships are being attacked by GDI, killing everyone inside the ships. Those who are survived have jumping out of the ships and tried to swim to safety.

Britannian sents britannian jet fighters to deal with invaders but they are no match against GDI interceptors as they shoots vulcan guns and rockets. Britannian has lost most of the jet fighters while GDI lost some of the interceptors. Britannian Caerleon-class floating battleships was sent out to deal with invaders though they are not prepare against GDI grizzly battlecruisers, kodiaks, and philadelphia cruisers. The britannian captains from each floating battleships are completely jaw-dropped then the GDI kodiak forces fires upon Caerleon floating battleships, despite they were protected by shields, they have being shot down by multiple attacks and went down from the sky.

At the ground, GDI drop pods deployed in Hawaii and GDI forces are preparing to invade it. They're leading by a same commander fought in Narita, LT. Strongarm. And this time, she's using a new knightmare called Equitess, and it was built by herself.

Strongarm: Alright, boys! You know what we're here for. Time to kick some ass.

Equitess and her GDI forces rushed through enemy lines as they eliminate britannian forces. Equitess shoots her flak cannons at enemy knightmares at the front. GDI behemoth fires sonic grenades on britannian armed vehicles and shoots quad AA railgun at 5 britannian VTOL gunships. GDI war dogs shoots at britannian soldiers. A squad of sutherlands go straight to Equitess as she noticed them so she jumps in and slashes them by her sword. Few GDI paladins fires at britannian supply trucks and tanks.

After the bombardment on britannian navy base, the remaining britannian navy ships are still intact and they headed to Area 11 but they are being outnumbered by huge GDI navy forces. They have no choice but to surrender to the invaders.

Strongarm and her forces have taking every territory in Hawaii to take down military britannian forces like a wildfire. After they took out the last remaining britannian forces, Hawaii has being taken by LT. Strongarm.

...

Shinkirō is on the air as Tokyo Settlement has become a fortress. The entire britannian forces are standby ready to take out the enemy. Calares was at behind the line to observe the enemy planning to attack in full force. He thinks they are dumb uncivilized monkeys thinking they can go through his army by force. But what he don't know is Zero has other plans for him. Shinkirō reaching to the sky as he said using a speaker.

Zero (on speaker): Britannian! Hear me, I'm a rebel who oppose those using power to abuse for their selfish ways.

Calares scoffed that he will be scared of him but his confidence shows he will win the battle. But he still doesn't know about Zero motives. Meanwhile, Lelouch take off his mask as he see his left eye has activated the Geass. He make an evil smile to commence the attack. C.C just said to him.

C.C: Lelouch.

Lelouch: Hm?

C.C: If we succeeded taking over Japan, what are you going to do?

Lelouch: I'm still getting on my ideas. My plan should be mine, but the GDI has intervened my images. Attacking them is a death sentence and we will meet his allies.

C.C: Once we do this, there's no turning back. And Lelouch...

Lelouch: Hm?

C.C: Do you trust them? The GDI?

Lelouch: Only to take out our common enemy. Now, it's time to bring the destruction on mighty army of britannian!

Then, the countdown is finished as something is happened in this moment. The outer block begun to crumble as alll britannian forces are wipe out completely. Calares watching his forces
crumbling into the abyss and he's completely shocked.

Calares: No! It can't be!

Zero watches the britannian forces being send to their doom as every platform has fallen apart. He make an evil laugh.

Lelouch: HAHAHAHAHA!!! Yes, I can do it! I will destroy britannian!

C.C: Lelouch.

Lelouch: Huh? What?

C.C: I'm receive word that GDI has arrived.

Lelouch: By air transport?

C.C: No. From above the clouds.

Lelouch: Above?

He look up to see multiple GDI drop pods came down from the sky and hit the ground to deploy troops. Both infantry and ground forces are ready to take a fight against the enemy. They were lead by Tanya, Jäger, and Spectre to face against the enemy. The Black Knights and other Japanese resistance forces are taking a lot of surprise to see them coming from the sky. Kaguya was amazed to see the actions of new ally of Black Knights. Lelouch got receive call from the screen and see Tanya is on it as she said.

Tanya (on screen): Lelouch, are you there?

Lelouch: Yes. But you can call me Zero. Now, I'm taking command of this operation so here are your instructions.

Tanya (on screen): No thank you, Zero. Our supreme commander have giving us orders before we arrive here. Now, hear me out: Our specialist, Spectre, will be headed to Ashford Academy for set up an outpost there. We'll using our defense crawler to protect the students. My friend and I will lead our forces and fight alongside with your guys.

Lelouch: Hmph. Very well, then. Now let's begin to attack!

After that, they charges through the battlefield towards britannian government bureau.

...

Henry was watching on the screen as they able to take over the area within Japan. Not only that, the Alter-Japanese milita forces have also joined in to take over other territories. He contact Jack and Euphemia and then he said.

Henry: This is supreme commander Jefferson, what's the status there?

Jack (on screen): We'll manage to penetrate through enemy defenses. The britannian police forces have joined military forces to block off our forces. But we able to beat a right on them.

Henry: Good. But remember, we don't want the civilians who still out there get shot by one of our guys.

Jack (on screen): Got'cha.

Euphemia (on screen): Mr. Jefferson, I don't know about this. But I fear there are so many deaths fighting so blindly.

Henry: It's war, your highness. Your father have taking so many lives for colonize every land they have took from people. And I want to end it.

Euphemia (on screen): I understand. But, is there other way to stop it peacefully?

Henry: For what I know of intel, Calares has taking over as new viceroy and I doubt he will listen to you since you are our side. If we take him out, it is a good time for you to speak out your people to stand down and surrender to end this war.

Euphemia (on screen): I see... Contact me when new viceroy is dead.

Henry nodded her. The screen turns off and he continues observing the battlefield.

...

Ashford Academy

Milly and her friends watching on TV as the outer block has being crumbled into the ground. Shirley felt scared of this situation and hoping her family went to shelter for safety. Milly looking at the TV until she got a call on her earpiece so she went out of the room and said on the comms.

Milly: Yes?

Spectre (on comms): This is Spectre, GDI specialist, Delta Eagle Force. Are you Milly Ashford?

Milly: Y-Yes. That's me.

Spectre (on comms): Good. Now listen, we're planning to take Ashford Academy for our outpost.

Milly: O-Okay. Just make sure there won't be student casualties.

Spectre (on comms): We'll keep that in mind, Ms. Ashford.

Milly takes a deep breath before she went back to the room and Rivalz just said.

Rivalz: Hey! Where did you go?

Milly: Nothing much. But anyway, we have to stay here and remain calm. There's no need to be panic. We will be okay as long as we're here.

Shirley: R-Right. I'm just hope my family is safe.

Rivalz: So do I.

Nunnally: I'm still worrying about my big brother.

Shirley: You mean, Lulu? I don't know where he is? Is he still in school?

Rivalz: I don't think so. He's at outside.

Shirley: During in the time for this?!

Rivalz: I hope he will be fine, probably hiding somewhere from the battle.

Nunnally: I hope so.

Milly lowered her head worrying about Lelouch being Zero fighting against britannian military forces alongside the GDI and the allies.

Milly (thoughts): Lelouch... is this a path you must take for your revenge?

...

LT. Smith and the others keep fighting through enemy lines as they're pulling back. GDI and allied forces goes straight in full speed, but then they were being surprised attack by enemy sutherlands led by David T. Darlton.

David Darlton: I got you now, you invader scum!

LT. Tom and the others are able to take cover at the building. Few GDI and allied forces have taking a lot of casualties because of surprise attack.

Daniel: Mapahamak ang mga britannian! They're pulling back so they can put surprise attack on us!

Jacob: I don't think I can take 'em all of them.

LT. Smith contact on his comms as he said.

Tom: This is LT. Tom Smith, we need to clear the enemy, sir! I have coordinates on my location.

GDI operator (on comms): Roger that. I'm sending orbital strike on your location.

Tom: Got it. Everyone, take the cover! Orbital strike has been authorized!

Everyone went to take cover to the safe place from orbital strike. David Darlton and his forces keep hailing on them as The Allied forces are retreating.

David Darlton: Ha! They're starting to scare of us. All men, move forward to victory!

David Darlton and his forces rushed towards the enemy when orbital strike came down from the sky explodes everyone in the area, including David Darlton and his forces. After orbital bombardment, The Allied forces continue to push on.

...

Bartley: What?! David Darlton forces are wiped out?!

Britannian officer: Yes sir. They are total annihilated as we speak.

Alicia: Goddamn it! Those invaders have wiped out the entire battalion. How strong they are?

Schneizel: We're not sure yet. But this so-called GDI seemly have good strategy and tactics to know the battlefield.

Alicia: Are you saying he has experience as a soldier?

Schneizel: That could be impossible to know about his organization. However, we must be prepared of what comes next.

...

Shinkirō fires hadron cannons on all britannian air forces from government bureau that tries to bomb on his ground forces.

Kallen and the entire Black Knight forces goes in front line to take out britannian ground forces in the rubble of outer block.

Edgar: Yes, I understand...

Then suddenly, Tanya riding on her knightmare, Lady Fighter, appears after she took out a sutherland. This make Edgar enraged for she is responsible of both brothers killed in Narita so he engaged her.

Edgar: Murderer!!!

Claudio: Edgar, wait!

It's too late for Claudio as his adoptive brother goes attack Lady Fighter. Lady Fighter saw a glouscester coming for her in full speed.

Edgar (on speaker): You bitch! You'll pay for against the empire!

Tanya (on speaker): An empire that took people's freedom, especially Japan.

Edgar goes to swing his sword at her bt she suddenly disappeared.

Edgar: Huh? Where did you go?

Then, she appears behind him as she stabs through the chest then cut him in half and explodes into pieces. Claudio watches him being destroyed by her just realizes he has no chance against her so he went retreat. Iron Shooter fires sniper rifle at sutherland's head then switch to assault rifle to destroy other sutherlands. GDI predator tanks fires rail accelerators on every britannian ground forces. The Japanese resistance have also joined them to fight on the enemy.

Calares: We're started to losing this battle!? Where the hell is reinforcement!

Britannian officer 1: We still no contact from Hawaii base.

Calares: What about from the homeland.

Britannian officer 2: We can't, sir. They wouldn't reach in time.

Calares: Damn it! Just send everyone who are available to attack. Attack, all of them! We will never surrender to uncivilized savages!

...

The Slayer and his forces come to Ashford Academy for setting up an outpost. Spectre gets out of his knightmare and pinpoint to deploy defense crawler on his location. Defense crawler is deployed and turn into construction yard mode and built defense structures around the school such as falcon MLRS, focus beams, and skystrike artilleries. They also built tunnel to get his troops here from the other side of the battlefield. Spectre and his troops goes into the school to secure the place. Spectre reached to the room where Milly and the others were here and GDI soldiers are surrounded them.

Spectre: This is GDI! On the ground and put your hands on your back where we can see them!

Milly: Rivalz, Shirley, do what he says.

Shirley: But-

Milly: Do it!

Shirley and Rivalz did what she said to them, they drop the kness and put their hands on their back. He approached toward her as he said.

Spectre: Milly Ashford.

Milly: Yes?

Spectre: Follow me.

Milly: O-Okay.

Nunnally: Milly.

Milly: Don't worry, I'll be fine.

Both Spectre and Milly headed out of the room. Spectre said to her.

Spectre: Okay, I've see everyone are still here.

Milly: Of course. Every student have their dorms once they enroll here.

Spectre: Right. Now listen, I'm ordering to place all students into gymnasium where they won't go out during this situation.

Milly: Yes, I understand. I'll convince my grandfather to put the students there.

Spectre: Good. And before we can do that, are there anyone you know is missing?

Milly: Well, my friends are here except- Oh god.

Spectre: What?

Milly: Nina. Nina Einstein isn't with us. I've never known until now.

Spectre: Okay, okay, calm down. Now where is she?

Milly: Um... It's at underground storage below the school.

Spectre: Okay. Take your friends to gymnasium while I get to her.

Milly nodded before he get his troops and headed to underground storage. Milly went back inside as she said.

Milly: Everyone, time to go.

Nunnally: Where are we going?

Milly: To gymnasium, where it is safe.

Shirley: But-

Nunnally: Shirley, we have to listen to her.

Rivalz: I agree with her. Besides, Lelouch will be safe for now.

Shirley: *Sigh* Okay.

Milly: Good! Excuse me, sir. Can you take us there?

GDI rifleman: Of course. Follow me.

Milly and the others follows a rifleman to a gymnasium where they put students there for safety.

Meanwhile, Spectre and his troops are in underground storage to find Nina Einstein somewhere here.

Spectre: Listen up, switch it to stun gun. A girl named Nina Einstein, basically like Albert Einstein. Remember, don't kill her.

As they continue searching for her, they saw a knightmare which is called Ganymede.

Spectre: A knightmare? Here in below the school?

GDI rifleman 1: Sir! There's something attachment on that thing.

GDI rifleman 2: Holy shit. That's a bomb!

Spectre: A bomb.

???: Stay away from me!

They look a person riding on a knightmare. A green-haired girl wearing an eyeglasses and dresses a student uniform.

Nina: Don't you dare come closer to me or I'll detonate this bomb!

Spectre (thought): Shit. That must be Nina Einstein and she has a detonator on her hands. Like Albert Einstein, she has an idea of creating bomba but it's not nuclear. I have to stop her from blowing up this school.

Spectre: Nina Einstein, this is GDI! Put down a detonator and no one gets hurt.

Nina: I don't want to hear from you! You took Princess Euphemia and put  against her will!

Spectre: No, we're not! She is perfectly sa-

Nina: Shut up! You'll release her or I'll blow you up into the kingdom come!

Spectre: Okay, the negotiation won't go well. Shoot her.

A rifleman fires stun gun at her and she knock out cold. She fall from a knightmare as Spectre catching her on his arms and a detonator is fell on the floor. A rifleman picks it up and place it somewhere safe.

Spectre: Let's get out of here.

...

Henry saw that his Allied forces have successfully defeated the britannian forces on every region. Now, the only left is Tokyo Settlement. He viewing ok the screen to see G-1 base near behind the government bureau and behind of his full britannian forces to protect the line from the enemy. He wanted to keep fighting through the enemt forces although it may take some time to get there so the only option is using one of the superweapon of GDI existence. He radio contact to Ion cannon center and he said.

Henry: Operator, this is Supreme Commander Jefferson, has the Ion cannon ready?

GDI operator (on comms): Ready as you're ordered, sir.

Henry: Good. Fire a target on that location. I'm sending you a coordinate.

GDI operator (on comms): Roger that. Ion cannon ready to fire.

...

Calares can't believe his army has failed to defend Area 11 and the homeland take a long time to arrive here before the sunrise. He can feel his body shaking in fear as he's about to lose. Then, his officer goes to him and said.

Britannian officer: My lord!

Calares: What is it? Can't you see I'm trying to concentrate the battle strategy?

Britannian officers: Forgive me, but there's something unknown coming this way!

Calares: What!?

Outside the G-1 base

Britannian remaining forces are remain defening this road to protect their viceroy and government bureau when something is happening today. The light from the sky is starting to getting brighter as few lasers circle around the G-1 base and goes into a straight point. The britannian forces have no idea what it is until it's too late.

...

On earth atmosphere, the Ion cannon started to charging up and then it shoots directly toward Japan.

Onboard of GST Angel Sword, Vicktor watched on the screen as Henry have authorized to use a superweapon and fire on Alter-Earth target location.

Viktor: And so, the Ion cannon has introduced to the world itself.

...

The Ion Cannon strikes down upon G-1 base causing to explodes widely to destroy every britannian force within that area. Calares see the blue light is getting brighter and brighter until it closed into the existence.

Calares: No, no, no, no! NOOOO!!!

And with that final scream, Calares has being killed by Ion cannon, along with the rest of his forces.

...

Lelouch and everyone else fighting the britannians has stopped after they saw a blue light beam destroyed Calares and his entire forces. Once it's over, they saw terrifying moment to see a viceroy and his forces has wiped out in one blast and leave nothing but ashes.

Lelouch: W-What did I saw...

C.C: I have no idea...

Back to the ground, Tanya and Jäger get out of the cockpit and see that Ion cannon has fired upon Calares position and eliminate all of them.

Jäger: Alle Mutter Gottes. He did it. He authorize the Ion cannon.

Tanya: I can't blame our supreme commander anyway.

Kallen, Tohdoh and the others came to them as they said.

Kallen (speaker): You there! What the hell is that!?

Tamaki (speaker): Yeah! Explain us!

Tanya: That, my friend, is an Ion cannon. A superweapon of GDI.

Ohgi (speaker): So, he used that weapon on...

Jäger: Ja. The new viceroy.

Urabe (speaker): So that's what Ion cannon can do on the battlefield.

Kallen (speaker): Hang on! You know this?

Nagisa (speaker): Yes. He told us what it is and what it can do on the battlefield.

Tohdoh (speaker): A mass weapon that can take out a huge army in one blast. They've used it in tiberium war.

Tamaki (speaker): Wow... That sounds scary.

...

Suzaku and Goro Azuma just saw the blast of the Ion Cannon near the government bureau in the distance.

Suzaku: W-What the hell is that.

Goro (on comms): That is Ion Cannon.

Suzaku: Huh? An Ion cannon?

Goro (on comms): I've read about that weapon. A satellite superweapon on the orbit used to annihilate the enemy in one blast. They have used it against Brotherhood of Nod and The Scrin in the tiberium war.

Suzaku: It's so much power for a human being.

Goro (on comms): It's war, Suzaku. GDI have experience it on their war before coming to our world.
