Summary: What if the Black Knights did not betray Lelouch?

The Promise

Chapter One: Battle for Japan's Liberty

"Black Knights!" Zero said "our final battle for Japan's liberty is about to begin. It won't be easy for us because the enemy have the FLEIJA warhead. Some of us might not be able to come back, but their sacrifice won't be in vein. After this battle, Area 11 will be Japan again, and a new world will be built".

The Black Knights trusted Zero even if they knew about his real identity, even if he is Lelouch vi Britannia, Britannia's 11th Prince.

A communication line from Schnizel opened.

"Zero." the prince said flatly.

"Prince Schneizel el Britannia, I did not expect this. Are you going to surrender?" Zero said in a mocking tone.

"The one who must surrender is you, Zero."

"Why should I? Victory will be mine."

"Looks like we have to settle this at the battle field, Lelouch."

The communication line was closed.

Zero is about to enter his private quarters when he heard Kallen call him.

"Zero!" she said hurriedly.

"Kallen?" Zero said, "aren't you suppose to be preparing for the battle?"

"Well, I just want to wish you goodluck" she said flatly, "I'll go and start preparing"

"Kallen!" Zero called, "can we talk?"

"About?" the red-head ask.

"Come in first."

They entered the room, Kallen looked around looking for the green-haired witch, Kallen settled herself on the couch. Lelouch put off his mask and sat next to Kallen.

"Where is C.C?" Kallen asked.

"Probably eating pizza" Lelouch said.

"So, what do you want to talk about, Lelouch?" she asked curiously.

"I just want to remind you about your promise." the former prince said.

"Don't worry" the red-head started, "I won't breake my promise."

"I know" the prince said flatly, "you always keep your promises."

"So, what's the point of reminding me about it?"

Before Kallen knew it, Lelouch hugged her. "I just want to be sure you remembered it" Lelouch said in a worried voice "Icant manage to lose another person dear to me." Then he free her from his protective arms. Lelouch looked into Kallen's eyes, She can see the worry and fear in his eyes. "Kallen, Iwant to hear it again from you. Promise me you will return to Ashford Academy with me, when this war is over" Lelouch said almost pleading. She stared at his eyes for a moment, then she spoke "I will return to Ashford with you, Lelouch. That's a promise" she assured him. Lelouch can see sincerity in her eyes.

He cares about me? Kallen thought, Is it possible that he feels the same way too?

After this battle, I'm going to tell her what I really feel about her. It's going to be over after this, the prince thought.

Kallen broke the silence between them and said "I'm going now, Lelouch. I have to prepare for the battle." She said.

"Okay" the prince said lightly, "and googluck."

"Thanks" the re-head said while waving.

When Kallen was gone, Lelouch heard a familiar voice which irritated him.

"Looks like you had a good time, boy"

"Witch" he said irritated

"the battle will start in a few moments and the commander of the Black Knights is here, thinking about his girlfriend instead of planning for their strategy" the green-haired witch teased.

"I already have my plans, witch" the prince said with a smirk.

C.C did not reply.

Battlefield

Kallen positioned her Guren beside Shinkirou while waiting for a command from Zero when a communication line was opened.

"Kallen" said Lelouch

"What?"

"Stay beside me. I need you to back me up?"

"Okay"

Kallen was looking for Lancelot, but it was no where to be found, she then opned a communication line to Lelouch.

"Lelouch looks like Suzaku is not with them"

"I noticed that too."

"This will be easier if he will not show up."

"I hope he wont"

She cut the communication line.

The battle has now started, still Suzaku Kururugi did not show is facing Gino who opened a communication line.

"Looks like we really need to fight, don't we Kallen?" Gino said

"You can simply surrender if you're afraid"

"Unfortunately I'm not"

"Then, I'll have to defeat you Gino"

Kallen cut the communication line and started charging at Gino using her long fork, Gino blocked her attack with his sword.

They fought for 15 minutes, Kallen's long fork was cut into two pieces, while Gino's wing was damaged and is giving him a hard time flying.

It's time to end this Gino, Kallen thought. She attacked Gino using her right arm, she fired Guren's radiation straight to Tristan's face. It exploded but Gino managed to eject.

Kallen saw Anya chasing Lelouch so she followed them. She managed to Chase Anya and now she is in front of her. She opened a communication line to Lelouch

"Lelouch, go ahead, I'll take care of her" the red-head said

"But she have a FLEIJA with her."

"I'll be fine, you have to catch Schneizel?"

"You'll follow, right?"

"I will"

When Kallen saw Lelouch flew to the direction of Democliest, she started charging at Anya. Ineed to be careful or I'll die, the red-head thought, I must be able to defeat her before she fires FLEIJA. Anya started firing her cannons, Kallen was able to avoid all her attacks. She dodged around Anya trying to avoid her attacks and at the same time looking for a good spot to attack her. Anya was able to hit Guren's wings, Kallen was forced to land at the left wing of Democliest.

"Damn it!" Kallen wings are broken and she still have FLEIJA, I have no choice but to try this, Kallen thought. She jumped towards Anya and tried to attack her using Guren's clause, Anya caught her left arm and pointed a cannon on her, before she fired it Kallen fired her radiation on her. Kallen freed herself from the Mordred but when it exploded she was still in reach. She experience violent shaking and hit her head causing it to bleed.

She was about to faint when she remembered that Lelouch is waiting for got out of Guren still feeling dizzy.

Kallen saw Lelouch standing in front of Schneizel who is pointing a gun on him and wearing a visor. He's in trouble she thought, she started running towards them. Schneizel pulled the trigger but Kallen was able to push Lelouch, who landed clumsily on the ground. Before Schneizel can react Kallen punched in the stomach causing him to lose consciousness.

"Kallen are you okay?" Lelouch asked while standing up. "I'm fine" she lied and turned her back from him. "You're bleeding!" Lelouch exclaimed.

"You were shot!"

"It's nothing, really"

"That's ridiculus! You were shot and you"re telling me its nothing!"

"Don't worry Lelouch, I won't die because I was shot" she said turning to face him

"Your head is bleeding too" he exclaimed

"I'm fine" she said weakly.

Kallen is now feeling really dizzy and the throbbing in her head got worse, she 's tring not to faint. I cannot faint right now, not in front of Lelouch she thought, but she failed, she fainted.

"Kallen!" Lelouch said who was able to catch her, he cradled her in his arms "Kallen, can you hear me?" she did not responded "please open your eyes, Kallen, please!" Tears started flowing from his "you cannot die! You promised me"

Lelouch lifted Kallen bridal style and headed to his Shinkirou. He settled her on his lap, head is resting on his shoulder and one of his arms held her protectively, he then whispered to her "I won't let you die, Kallen, not you."
