The Port Yokosuka that suppose to be accomplished for the Black Knights and Frontier Militia wasn't expected to have new player to intervene their operation. As they busying fighting Britannian forces led by Cornelia, the Enclave stepped in and attack everyone whether Black Knights, Britannia, or Frontier Militia. The Enclave forces attacking the Britannian forces and then Frontier Militia as they using everything to destroy them. The Black Knights have also being under attacked as well as the Enclave aggressively goes towards them to attack. 

Oscar and the others face off both Enclave and Britannian forces while they fighting each other. Dorothea take out Enclave sutherlands that tries to surround her.

Dorothea: Fools! Have you not hear from me before? I am a part of the Knights of the Rounds, loyal to the emperor, you shall regret it to face me!

Her knightmare open fire the hadron cannons as five Enclave sutherlands are destroyed. She kept going to attacking them until she saw Oscar and the other fighting them. She went up towards as she raise her large hand turning into a fist and attempt to smash them.

Dorothea: Die!

One of Oscar Team, Keshly, saw her coming and warn his teammates.

Keshly: Guys! Look out!

They noticed as they dodge the attack from Dorothea. They are on the stances as they facing her in the middle of this situation.

Danny: Shit! She still fighting us during this situation?

Oscar: She doesn't care anyway! As long as we are the threat of Britannia in the future she won't give up until we're dead, 

Oscar and Danny splits up as they went different directions to make Dorothea choose to which one will she after her enemy. So she pick Oscar and went after him.

Meanwhile, Ling and Keshly is busying fighting off against either Britannian or Enclave forces in each places. Ling slashes enemy sutherland in half with her arc broadsword. Keshly shoots at two or three enclave sutherlands at each time then he shoots his battle rifle at Britannain sutherland attempt to fire slash harken at him. These two continues fighting the both different enemy factions in the port. The Frontier Militia infantry and ground units were busying fighting two enemy factions as well as they could destroy them in a lot of damage.

The Black Knights are small, but very determined and follow Zero strategy as they attacking small Britannian forces and large number of enclave sutherlands in every place. Zero didn't expected the new enemy have waiting to strike while he and the others are busying to fight against Britannian forces.

...

Shirley was being held by Augustus' men as her father was feeling being threatened and Villetta just stand still pointing her gun at them. Augustus see that she is alone and she wasn't with Britannian forces fighting against SRA, Black Knights, and The Enclave. He make a smirk on the face as he said.

Augustus: So, you must be Villetta Nu, "former" member of Pureblood. I didn't expected to come here.

Villetta: Former? 

Augustus: That's right. Since the Pureblood faction in Area 11 have betrayed your own country and they're working with us.

Villetta: So, it was you who make them betrayal of the Holy Britannian Empire! You persuade them!

Augustus: Perhaps I am. It's just that since the "Orange" incident Kewell and the other members of Pureblood seeing Jeremiah Gottweld to be blamed for ruining their reputation so I did what I could to give them something more than reputation.

Villetta: And what's that?

Augustus: Loyalty to the Enclave.

Joseph: E-Enclave?

Augustus: Yes. That's what we called ourselves. We are going to change the world once we unleash our fury upon this world and it will be soon in our grasp.

Villetta: You sound like you can take over this world. But I see a small number of terrorist impossible to win.

Augustus: Oh, but it was only beginning. But it is unfortunate you won't see it.

Villetta: Huh?

She is confused before she suddenly got shot by a sniper and fell on the ground. Joseph and Shirley look in horror they killed her.

Augustus: Dump the body.

Two Enclave commando comply his order and carry Villetta to dump her somewhere. What they don't know is that she still alive and she is in unconscious. Augustus face at him.

Augustus: So where are we?  Ah yes, thank you for giving me your research documents about Geass that you work for Prince Clovis and Gen. Bartley. You make a very good work for your career.

Shirley: Daddy, what is Geass. What is this about?

Augustus: Oh darling, he has secrets that you wouldn't know everything about his work. But since you are here and you know everything too much...

He pulled out Oni pistol and points at her.

Augustus: Then I'm afraid you have to be taken out.

Shirley's eye widened in horror as she fear of her life being threatened and she was going to die here where no one will miss her except her friends and her lover, Lelouch Lamperouge. She is in a verge of tears as she is going to die when suddenly her father pulled out his pistol and points at him.

Joseph: Let my daughter go right now!

Augustus: Oh? Looks like Daddy here has come to save his daughter.

His commandos are pointing their weapons at him.

Joseph: I have been scared when I got out from Narita when it become a warzone. I survived to escape the facility from your men when my colleagues are either killed or captured. You try to blackmail me when you tried to threaten my family. I cannot allow to be happen of what I have just done. My daughter isn't part of this. I do!

Augustus: So you admitted that you lied to your daughter about your job as a car selling guy. A scientist conducting the human experimentation ordered by Prince Clovis and Gen. Bartley.

Shirley was loss of words of what her father's job isn't about selling cars. It's about human experimentation. She can't believe her father lied to her from the start when he got a job when she was born. She also can't believe he is working for Prince Clovis who is responsible of order the massacre of Shinjuku ghetto. Joseph was guilty of his daughter's reaction but he does not cared. He will save her daughter so he can atone his sins.

Joseph: I may lied to my daughter so she can have a perfect life, I have to for my family. Even actions I committed bring more sins onto my shoulders, I'll do anything for her.

Shirley: Father...

Augustus: Ah... Love for a daughter. Such an emotional scene. But emotional can be advantage.

Joseph is confused and suddenly Augustus quickly kick the gun out of his hand and then he got shot to the body chest.

Shirley: Father! No!

Joseph cough out in blood as Augustus walks toward him with the gun pointing at him.

Augustus: It is a pleasure to meet you in person, Joseph Fenette. And now, your future comes in the end with one bullet.

He pulled a trigger and a bullet goes to Joseph's head. Blood comes out spreading on the ground. Shirley's eyes widened as her heart crashed into million pieces. She watch her father was shot by that man and she couldn't do anything to save him despite how her father have lied and commit horrible experimented on human beings, he still love her no matter what. Tears flows down the cheeks from her eyes. She cried out her father.

Shirley: FATHER!!!

...

Zero is aiming the battle rifle at Cornelia's gloucester pinned down when he hear the woman loud voice.

???: FATHER!!!

Zero: What the? That scream. It sounds like...

But he was cut off by Lancelot surprise attack from the air. He kicked at knightmare's face and slides him on the ground. Zero take a badly damage as his knightmare lose some of the pieces. Lancelot focusing on him now he is on the ground damaged.

Suzaku: Zero! Your methods won't change anything! You focused on goals, and don't understand the pain of others.

Kallen: Zero!

She went to save Zero when Lancelot Club piloting by Nonette jumps to the air and land it to block her path.

Nonette: Not so fast, Eleven!

Kallen: Get out of my way!

She was going to attack when suddenly Blisk's titan jumps out of nowhere and charge attack Lancelot Club in full power. Nonette got knock out and fell to the ground. Blisk is in the center surrounded by his enemies. He feel interesting to face all them at once.

Blisk: Hmm... Seems these people are busy here. Mind if I join in.

He raised predator cannons to ready himself for a fight then someone spoke to him.

Nonette: Hey!

He turns around to see Lancelot Club is getting up and draw out the swords to fight him.

Nonette (speaker): You dare interfere me!

Blisk (speaker): Oh shut up already.

He pointing his weapon and open fire at a knightmare, destroying every pieces that bullets hail on her. A Lancelot Club is shredded into the pieces forcing a cockpit to eject to the sky.

Nonette: Damn it! Why!!!

Once she's out of the way, Blisk turns at Guren MKII and prepare to fight.

Kallen: Shit!

Blisk: Gotcha.

He started shooting his weapon as Guren quickly dodge the bullets and went on top of the rectangular crate box.

Blisk: Hey... Don't run away. I haven't finish you yet.

Then he sense something is coming for him. He turn around and saw Cornelia's gloucester charging towards him with her jousting lance.

Blisk: Oh no, you don't.

He dodge from an attack as he grabbed knightmare's arm and thrown her to the crate box and then he pulled out the left arm.

Cornelia: You barbarian!

Blisk: Looks like Viceroy is thinking so rashly.

He pulled out the knife and stabs to the torso and rip it apart and then he kicks her to the ground.

Cornelia: Damn you!

Blisk: Now time to die.

He raise his weapon and pointing at her when a slash harken just hit at the right side, but a bit effective. He turns around to see Lancelot is going towards him.

Blisk: Well... It isn't a knightmare I fought in Narita. I was looking for rematch.

Lancelot to kick him but Blisk dodge it and grab a leg and throws him to the ground. He draws out to pointing VARIS at him and open fire. He move around to dodge it and firing predator cannon at him. Lancelot tries to block the bullets by having forearm shields but it hits the legs forcing to kneel down. 

Suzaku: Why... Why are you people here for? More destruction? More bloodshed?

He getting up and went to attack when a volley of rockets hits him at the back.

Suzaku: I got hit! Who's firing at me.

He turn around to see Viper's titan flying on the sky.

Suzaku: What! It can fly!

Viper: Boss, I got a shot. 

He quickly firing his railgun as a projectile goes straight to the left shoulders ripping off the arm.

Suzaku: Gah!

Blisk charge attack to push him to the ground.

Blisk: Huh... It seems too easy. I wasn't expected for a challenge.

He's going to end him when suddenly Guren MKII comes back and kick at the face.

Kallen: Forget about me?

Blisk: Damn, I almost forgot about that. Viper?

Viper (comms): Roger that.

Viper's titan flies toward Guren as he kicks to the face and push her to the ground.

Kallen: Not bad! But try this!

She stands up and jump attack him using her weapon and then she tries to grab him with RWU right-arm but she failed. Viper flies away from her and firing volley of rockets upon her. She dodge the rockets and fires a slash harken at him. Unfortunately, it's out of reach when Viper's titan moves away to avoid getting hit in range. Zero got up and went to intercept the fight. Blisk turns around and open fire as he able to take out some of the pieces from Zero's knightmare. He dodge it and use slash harken to fly away but Viper notice it and fires rocket to shoot down a knightmare. Zero got hit and crash down to the ground as it ejects the cockpit to land nearby where Shirley is there.

...

Shirley was disheartened and her body is shaking to see her father is dead on the ground. Augustus men release her as she went to her dead father and tried to wake him up believing he is taking a nap.

Shirley: Father, father! Come on, wake up! Please! Wake up!

Augustus: I'm afraid he is not waking up.

He aiming his laser pistol to Shirley's face as she is shocking that he is going to kill her next.

Shirley: No... please...

She said, scaring of her life being threatened and her tears continue to flowing down.

Augustus: Good bye, girl.

He was interrupted when a cockpit is landed near them. Shirley, Augustus, and the commandos caught the surprise to crash to their position nearby.

Augustus: Men, check it.

The commandos raised their weapons cautiously as they approach it to see Zero is in unconscious. Augustus approach him surprising to see him here.

Augustus: So this is Zero. A man with a revolutionary ideals to bring down Britannia.

He grabs a helmet to take it off revealing his face.

Augustus: And not for that, a Britannian is leading them.

Shirley: L-Lulu?

She's shocked to see Zero was none other than her secretly boyfriend, Lelouch Lamperouge. He turns around at him.

Augustus: This man is your friend? Or your boyfriend. at least.

She lost her words as she tried to respond that question.

Augustus: Nevermind. At least I'm going to kill him nonetheless.

He pointing his gun at him.

Shirley: No!

She ran as she grab his arms and try to hold him down.

Shirley: I won't let you!

Augustus: Get off me, you bitch!

He shrugs it off and slapping her to the face as she dropped to the ground. He return to end his life when suddenly, Oscar came arrived in time. He gets out the titan and aim at them using R-201 Carbine.

Oscar: Alright, you Enclave bastard! Stay where you are!

RT pointing his assault shotgun at them.

Augustus: Well, well... Looks like the Union is here. Aren't you suppose to fight the Britannians.

Oscar: My guys will handle them. Now tell me, how did you get here and what do you want to this world.

Augustus: That I cannot answer to you. but to be fair point, we have access a portal technology to take us here. Now we are going to take it first before you Unions reclaim it.

Oscar: Not gonna happened, "colonel". Now put your hands up!

Then he saw Shirley on the floor is getting up from being slapped by Autumn.

Oscar (thoughts): Shirley? What she- Nevermind, gonna focus on him.

He return pointing a gun at him.

Oscar: I'm taking you to the custody.

Augustus: I'm afraid not.

Oscar: And why is that?

Augustus: Because I brought my own knightmare.

He reached out his remote and press it as a customized sutherland comes out from inside the warehouse and it's prepare to attack.

Oscar: Whoa!

Augustus: Let's see if you can handle to face me in combat.

His knightmare take a knee and grabs him to putting him into the cockpit.

Dorothea: No! I can't-

She cuts off as Ash use all of her might to pulled out the cockpit and throws her out of the knightmare to somewhere else in the port.

Ash: This is Ash, a member of Knights of the Round has defeated. Go to the next one.

Husk (comms): That won't be necessary. I have something to make him turn to our side.

Ash: Oh yeah? How?

Husk (comms): Trust me.

Luciano continues to attack Frontier Militias and Black Knights in the area when someone contact him to in-coms.

Luciano: Huh? Someone contact me during the fight? Who is this?

Husk (in-coms): I can answer the same thing. Who are you first, Knight?

Luciano: I am Luciano Bradley, I am Knight of Ten. Now, identify yourself.

Husk (in-coms): Call me Husk.

Luciano: Husk? Now tell me, what is your business to interrupt me for fighting these vermins.

Husk (in-coms): First, I would say my apologize for my men to kill your men for they are fighting against those enemies.

Luciano: Oh... So you're the one who ordered your terrorists to surprise attack.

Husk (in-coms): Yes. First, we destroy Japanese general in the freighter, and next, this is where I come to you. I want to meet you in person but not in the right time unless you decide to meet me right now with all of the commotions. I have something special offer for you, something that can satisfied of your sadistic bloodlust.

Luciano: My satisfy of my sadistic bloodlust...?

He started to chuckle with his evil smile.

Luciano: I'm listening...

Meanwhile, Guilford and Darlton riding their knightmares are having difficult situation as all enemies are facing together and they lost so many men in the battle.

Darlton: It's no use! We have to retreat.

Guilford: But we haven't receiving orders from the Viceroy. We must hold out until we receive order from her highness.

...

Shirley is sitting beside unconscious Lelouch still exposed to his face as she is still shocked that he is leading the Black Knights while he is a Vice President of Student Council. She cannot believe of what she have witness around here. She can't explain what is going on here.

Shirley: Lulu, why are you fighting against Britannian? Is it something on your mind that makes you become this?

???: Ah... I see someone come here during the battle.

It caught her a surprise as she turns around to see C.C wearing a casual clothes used for disguised in the public.

Shirley: Wha- Who are you?

CC: His accomplice. Now what a girl like you doing here?

Shirley: I-- I come here to find out why my father coming here only to be ended up killed by those... men.

She started to verge in tears as she's saddened to watch her father killed in her own eyes. She wipe out her tears as she said.

Shirley: Listen, I-I want Lelouch to tell me a truth a-and I want to know what is going on here.

CC: Oh? So you're wanted to stay here and wait for him to wake up.

She nodded.

CC: Okay. That's your choice anyway.

Meanwhile, Oscar is fighting against Augustus in battle as they clashes in each other in few times. He swings broadsword around to hit him but Augustus dodge it then he draw out his battle rifle and fires at him. Oscar quickly use phase dash to dodge it and then he unleash arc wave which is a bit effective on him. Augustus took damage and fall back. As he was going to engage him, he got contact from General Husk on comms.

Augustus: Yes sir?

Husk (comms): Colonel, I have ordered to retreat. It's no point to continue this fight.

Augustus: Understood, sir.

He looking at him before he decides to leave the battle for retreat. Oscar sighed that it's over and he said to his titan AI.

Oscar: Hey RT, you alright?

RT: Affirmative. Just a sustain damage, but still functions.

Oscar: Good, good...

He look on the screen to see C.C and Shirley are there beside her dead father and Zero aka Lelouch still unconscious laying on the ground. He saw that Lelouch is no longer wearing a mask. He is so concern of what happens next.

...

Cornelia's knightmare struggles to get up despite of many damages on her. She contact her remaining forces for her next order.

Cornelia: This is Viceroy Cornelia...

Guilford (in-coms): Princess!

Cornelia: We retreat. There's no point of fighting here.

Guilford (in-coms): Understood, your highness.

...

The Frontier Militia and Black Knights saw the Britannian forces are retreated as well as The Enclave retreated in separate ways. This make everyone a sound of victory, but they failed to protect Gen. Katase and his remaining soldiers on the freighter. Ling and her teammates open their cockpits to see it's over for now. Keshly takes a deep breath to relief the battle is over.

Keshly: It seems like it's over.

Danny: Yeah. But what the Enclave are doing here?

Ling: Probably complete their mission that they failed in Narita, or they wanted to take us out tonight.

Danny: Or they're must be the ones who destroy the freighter boarding with a general and the members of Japanese Liberation Front.

Ling: I think they did it. Looks like the JLF is no more. The Enclave killed them.

Keshly: Man, those bastards always getting away with it.

Danny: Don't worry, we'll get them soon, bud.

Then, they getting contact from their team leader.

Oscar (comms): This is Echo-1, come to my position. We got a serious problem.

The Echo team look each other faces before they close the cockpits and went to his position.

...

Warehouse, BK headquarter

Lelouch aka Zero wakes up to see the mask is in his head. He rises up to see Kallen and the others are here for him.

Diethard: It's good to see you awake, Zero.

He groaned of waking up from unconscious.

Zero: What happened?

Ohgi: The Britannian and unknown enemy are retreated. Cornelia is still alive and leave immediately.

Zero (thoughts): Shit! I cannot believe I failed to capture her.

Kallen: Um, Zero.

Zero: Hm? What is it?

Kallen and the others look at each other faces and she said to him.

Kallen: Echo-1 wants me to bring you for something important at the room.

Zero: Hm? What something so important?

Ohgi: It's better to see it for yourself.

Timeskip

Zero entered the room and shocked to saw Shirley crying in her hands. Oscar and his teammates are not wearing masks which means she learn that these guys are from Ashford academy. C.C was here too for a reason. His eyes widened behind the mask to know why Shirley is doing here, and then he saw someone was covered in a white sheet. He look at Oscar as he said.

Zero: Oscar, what is this girl doing-

Oscar: Drop the act, Lelouch. Shirley knows your face. 

Zero: What?

Shirley: L-Lelouch.

He look at her seeing eyes filled in tears flowing down her cheeks. She was saddened of what happen here. He takes off his mask to reveal his face to her. His face felt guilty like he something did happen to her.

Lelouch: Shirley...

...

Somewhere

Percivel is parking at outside the a small abandoned house in the woods. Luciano is sitting with Augustus, Kewell, and Gen. Husk to meet them in person. He drink a cup of tea as they're having a conversation.

Augustus: I hope that's everything you learn from us.

He finished drinking his tea cup and place it on the plate.

Luciano: Oh man, I cannot believe the American rebels have find a way to another world where futuristic technology there that left behind by alien civilization. This taking so long time for me to accept it after you explaining the whole thing.

He look directly at Kewell.

Luciano: And I know why you turn your back on your empire.

Kewell: It is for the best of all of us. I lead my Pureblood and I am doing it so they can give me something they promise. Regretfully, I feel that I betray my homeland, but nonetheless I'm doing it anyway.

Luciano look at two Enclave officers.

Luciano: So, what the Enclave intention here on Earth?

Husk: I would like you to come to our side. Like I said, we can give you something to satisfy your bloodshed in the battlefield, if that's what you want according to your files.

Luciano: I see you're doing the homework. Yes. That's how I earn my title "Vampire of Britannia" from begin with. And what makes you think I can join your organization.

Husk: To change the world by Richardson vision. The nobles, they are always be so arrogant, so selfish, and so ignorant fools to protect their nobility by any means to keep their luxury. The Blacks, they should've not come to exist like your friend there which she is defeated in her first time. The royalties who struggles to take the throne when the emperor died. The emperor believes he can win, but he cannot see the enemy of the shadow will come to take his life without a warning. The Knights, they always rely on honor when killing the civilians from foreign countries to believe their righteous. The Holy Britannian Empire believes the conquest is only way to bring peace to the world, but soon, they will fall by resistance and terrorists because they dislike their ideas.

Luciano: She is overzealous woman. She always look down those who are lower-class citizens and Numbers. Also, I kinda agree with you for once.

Husk: That is why we need your skills to benefit for the Enclave. The Frontier Militia, they are just pretend to be organization revolutionary group. They are real military force of Sovereignty Republic of America. Not only America, they also other countries on other world that fled here.

Luciano: I see... If that's what you want, I would like to say something for you.

Augustus: And what's that?

He lean closer near to their faces.

Luciano: I am happily to join you guys to slaughter everyone in the battlefield, and build a new order. You have me, I can kill everyone in the battlefield. Is that okay for you?

Husk, Kewell, and Augustus look at each other faces for a second before Husk said to him.

Husk: Very well. It's pleasure to join us, Luciano.

They both shake their hands as Luciano has joining the Enclave in secret. His expression becomes chaotic as he will likely to kill more people in the battlefield just for satisfaction.
