After the ascension of Emperor Lelouch, two lovers from the Euro Universe are targeted by the Hearts of the Kingdom, this reality's Knights of the Round.
The Hearts' offer to join their ranks is rejected by both the Former Knight of Nine, Axel as well the Former Black Bishop of the Black Knights, Roxas.
The Knight of One, Ansem, brands the two veterans as traitors to the empire, making them criminals in Britannia's eyes.
Now hunted, with nowhere else to go, Roxas and Axel join the Black Knights yet again using Roxas' ties with Kallen Kouzuki, who is a Black Knight herself.
Now they are beginning their fight against Emperor Lelouch at the border between Britannia and the Middle Eastern Federation.
However, they are confronting none other than two of the Hearts of the Kingdom.
And these Hearts can use Geass................
Roxas and Sora are seen up in the skies.
Sora's Knightmares still have Roxas's Knightmare pinned.
Kairi and Kallen are also trading blows.
"Just give up! You can't beat me!" Sora says to Roxas. "There's just too much of my good looks and my Knightmare.....to handle!"
Roxas is on the defensive, blocking attacks from the attacks of Sora's Knightmare Copies.
Roxas attacks one of the Knightmares, only for the Knightmare to dissolve and reappear.
"Wow!" Sora says. "So, this is the Black Bishop? More like Black Bitch to me."
Roxas contemplates his current situation.
"Hmmm.....I can't call on Kallen to help since she's fighting the Knight of Two. I also can't attack blindly. That'll get me killed."
Roxas looks around his Knightmare and sees the Geass Conduit nearby his right arm.
He shudders to himself, recalling the day that him and Axel were experimented on.
"AAAAAHHHH!"
"NNNNOOOO!"
"I really don't want to use Geass if I don't have to."
Roxas's Knightmare takes another hit from the back.
A computerized voice speaks.
"REMAINING SYSTEM POWER:40 PERCENT. REMAINING ENGINE POWER:50 PERCENT."
"I don't have a choice..." Roxas thinks. "But, how can I use my Geass on an enemy that can become many enemies? Wait! My Geass allows me to control electricity and machinery depending on the power level. It'll take a lot out of me, but if I set my Geass on Full Blast, I might be able to destroy his Knightmare using his own operating systems. But first, I need some breathing space."
Roxas inserts his arm into the Geass Conduit as the shock takes effect.
Electricity begins flowing into Roxas's body.
"So, you can use Geass, too?" Sora says. "Yay! More fun!"
One of the copies tattempts an attack, but Roxas's Knightmare sends out a shockwave from it's body, attacking all of the copies and stunning Sora's unit.
"Cool!" Sora says. "Finally, some competition!"
Kallen and Kairi are also fighting.
Kallen is knocked back by pressure again as Kairi keeps pushing Kallen back with The Protection.
"I told you." Kairi says. "No matter how many times you attempt it, you'll never scratch me."
"Yeah, keep thinking that." Kallen thinks.
After five more repulsions, Kairi begins to breathe hard.
"Wow, are you persistant, or what?" She says.
Two more repulsions.
Kairi begins to grow tired.
"Damn!" Kairi says. "So, this was..... your game?"
"Yep!" Kallen says. After two more repulsions, she succeeds in pinning Kairi's Knightmare down a second time.
"Now, it's checkmate." Kallen says, placing her Knightmare's plam onto the enemy Knightmare's body.
As the radiation reaches full, Kairi gives a final bold smirk.
"You............might be able to defeat Sora and me..........." Kairi says between heaves. "But, you'll never demolish the Hearts of the Kingdopm. Our Darkness will swallow you!"
She then flips Kallen the bird as her and her Knightmare are destroyed in the pressure of the radiation's wake.
"Yeah, I've heard that crap before." Kallen says. "Find peace, you tortured soul."
Roxas and Sora are about to end their battle, too.
Sora summosn as many copies as he can as the shockwaves from the Key of Destiny dissolve them.
One carefully aimed burst from Roxas manages to hit his Knightmare.
"I'll break free of this eventually, you know." Sora says, pinned by the electricity stemming through his Knightmare's body.
"Yeah, but can you dodge this.....Bitch?" Roxsas asks. as he summons more than half of the electricity in his body, and then, VIA the Geass Conduit, adds it to his main cannons.
Sora's face borders on horror as he realizes the power output of Roxas's electricity.
"No.................." Sora says. "Please.................."
"I wonder what that trader would've said if he saw your face now......?
Sora starts begging for his life.
"Please!" Sora says. "I'll do anything! Money! Power! Whatever! It's yous if you let me live!"
Tears are streaming out of his eyes.
Kallen rushes beside Roxas and analyzes the situation.
"Roxas, what are you gonna do? If we let him live, he'll no doubt just turn on us again."
Roxas deactivates his cannons and silently remains motionless.
"Yeah, but..........He's so pathetic. He won't mess with us anymore. Even if he gives info out, it's not like Lelouch won't see it coming. Especially after he finds out that the Knight of Four was defeated."
Kallen speaks to Sora in a stern tone.
"Go while you still have a chance." She says. "You won't get another one. If you mess with us again, you'll just die."
"Thank you, thank you." Sora says, flying off into the distance with an evil smile on his face.
Kallen and Roxas begin to fly in the opposite direction when She notices that Roxas still has his Geass on.
"Um....Aren't you gonna----?" Kallen asks.
"Wait for it." Roxas says.
Screaming from a Knightmare is heard as Sora and one hundred clones rush at the two from the opposite direction.
Roxas unleashes his Electricity cannon on the clones without even truning around.
The cannon blazes through all of the copies and hits Sora directly.
"NNNNNNOOOOO!" The boy shouts as he is killed by the voltage.
One last copy is seen attempting to attack the Guren from behind, but dissipates before it can strike.
"Wow." Kallen says. "How low can some people go?"
"Very." Roxas says. "I've seen the lowest scum with my own eyes. Me................. and............... Axel.................................."
Roxas collapses in his Pilot's seat as his Knightmare begins to lose altitude due to a loss of control.
Kallen pick up his Knightmare with hers and carries him back to the Black Flagship.
Scenes switch to Emperor Lelouch and Suzaku, who are seen talking with Ansem and Riku.
"So, the Knights of Two and Four are both defeated?" Lelouch asks.
"I'm afraid so, my liege." Ansem says.
Suzaku faces Lelouch.
"According to intelligence, the two were defeated by two Custom Knightmares." Suzaku says. "One of them was the Guren piloted by Kallen Kouzuki. The other was a Knightmare that has been listed as inactive for over five months until recently."
"Five months, you say?" Lelouch says.
"Yes." Ansem says, interrupting Suzaku. "However, data on the pilot is very scarce. All we know is that the pilot's name is Roxas."
"The Black Bishop............." Lelouch says.
"Pardon?" Suzaku says.
"Back when I was Zero, I rescued two boys from a Britannian experimental facility." Lelouch says. "One of them was a blonde."
"Ah yes, I remember." Ansem says. "One of them was the Former Knight of Nine, Axel. His whereabouts are currently unknown."
"Suddenly, a blonde boy shows up and takes out one of our most prestigious Knights. Then, Roxas and the Blonde are one and the same....." Suzaku says.
"Not only that, but if Axel and him are lovers, then they must follow each other closely." Lelouch says. "Ansem, I'm afraid that the Knight of Nine is now a Black Knight."
"I saw this coming, I did!" Ansem says. "But, now what? Our information is not only in the hands of the enemy, but the enemy is an evil version of my own Kingdom Hearts!"
Ansem leaves the room, saddened.
Leloucdh and Suzaku look at each other.
"Ansem's really devastated about the loss." Suzaku says. "What should we do, Lelouch?" He's smart. But, he's also impulsive. If we don't do something, he might do something so stupid that it's affects the Zero Requiem directly."
"Relax, Suzaku." Lelouch says. "Having a barking dog at the end of a leash can create as much fear as a loose dog that can't do anything. In fact, we can use this."
"How?" Suzaku says.
"It's a surprise............" Lelouch says combing his black hair with his hand.
