I guess I made a pretty decent kick-off for this fic, and I do promise you, it will get more interesting. A lot more, I hope. Please leave me some feedback as to whether you like it or not. I'm also adding a little recommendation list for some soundtracks that could make the reading experience better.
I'll add a number of the soundtrack at the parts where it should be played.
1) Code Geass OST 1 – Nightmare
2) Code Geass OST 1 – Outside Road

It was spring, and the winter cold had not completely disappeared yet. The air was chilly, and the leaves had frost covering them in the morning. Still counting approximately 6 months since the death of Lelouch vi Britannia, the country had pretty much gotten back to normal. The malls were lively, and it was on this particular day that Kallen and Rivalz decided to go buy some supplies for the Student Councils stand at the Cultural Festival.

The Student Council had gotten a few more members, whom Kallen and Rivalz got along with pretty well. Only Rivalz and Kallen had gone for the shopping though, as it was the "leaders' commitment to the council", which Rivalz had simply stated to make himself look cool and respectable, to no surprise.

So, on to the shopping part. There wasn't really a lot for them to buy, as they had already fixed most of it. They were simply running a little low on supplies for their stand, which was the giant pizza, as usual.
They went from store to store, just buying some unimportant things, and the shopping trip went without flaws. Well, except from one little flaw. If you could call this flaw little, that is.

"Something doesn't feel right," Kallen suddenly stated, stopping in her tracks. They had just left a convenience store, where Kallen had bought herself a carton of chocolate milk.
"No, something definitely feels very wrong," She mumbled, and Rivalz just stared at her with a bewildered expression on his face.

"What are you talking about, Kallen? You aren't getting your peri-" Rivalz was interrupted by Kallen throwing herself over him, tossing him into the ground.
"Hey, I was just kidding, no need to take it so seriously!" Rivalz exclaimed with a slight laugh.

"Cover your face!" Kallen shouted, "Everyone, get down!" She yelled, but not many people seemed to react. Rivalz only looked at her with surprise on his face, and Kallen threw herself down over him.
"I said cover your face!" She yelled as she put her arms around Rivalz' neck and held him close to her chest, which made him blush furiously.
Of course, his thoughts were broken off by the loud bang following Kallen's commotion. The loud stinging noise in his ear muffled up all the screams around him. Kallen stood up again, looking around for the source of the explosion. Smoke was emerging from a store not far away from them, and it looked like a couple of people were hurt in the blast. Kallen started cursing to herself.

"H-how did you know?" Rivalz asked, panic in his voice. Kallen just shrugged her shoulders.

"I don't know," she said, "just a gut feeling."
At the same time, several Knightmares came jumping in through the windows, and Kallen could easily see that they were not Britannian forces.
"Shit! What the hell is their purpose here?" Kallen cursed, looking distressed. She wasn't surprised that someone would plant a bomb, but why come in with Knightmares afterwards? She shook her head and grabbed Rivalz, making him follow her as she ran towards a storage room.

'I'm pretty sure this leads to the cellar, where Lelouch regained his memories back then.' Kallen, thought, making sure Rivalz was still following her.
"We'll just have to hide here!" Kallen exclaimed as they came into a big, hollow room.

"How are you able to keep so calm?" Rivalz stuttered, seeming very stressed out at the situation. Kallen looked up from the feather like accessory she had dangling from around her neck, which now had a tiny, red light blinking faster and faster.

"You might remember what I used to do?" Kallen asked with slight sarcasm in her voice.
".. Oh." Rivalz retorted, looking down as if he felt a little stupid.

"Just hurry up already!" Kallen shouted, looking back at her necklace. Rivalz looked at her dumbfounded, literally having no idea what she was talking about. Kallen noticed that the red light was blinking much faster now, until it finally lit continuously.
(1*)"There!" She shouted just as a red object came crashing through a big window in the roof.

"Shit, they found us!" Rivalz exclaimed, looking completely horrified.

"Stay here, and stay hidden, you got that?" Kallen ordered him, before running towards the red Knightmare that was literally kneeling in front of them. She leapt onto its arm, running upwards on it, and then it opened up. Rivalz only stood there dumbfounded at what he saw.
Kallen jumped into the seat of the Guren S.E.I.T.E.N, and she tore the key away from her neck, plugging it in, and the face of the Knightmare closed, covering her completely.

"Engage systems!" Karen uttered as she started clicking away on the screen in front of her.
"It seems the new radio controlling in this key worked perfectly." Kallen grinned to herself before rolling away. Looking at the map on the display, she could see the position of the enemy Knightmares. There were 5 of them altogether, spread across every side of the main hall. She had to take care of this before Britannian forces arrived, or this might get ugly.

After looking at the display and quickly laying a plan, Kallen burst through a concrete wall, appearing behind one of the Knightmares. The situation so far looked like a hostage situation. The Knightmares stood completely still, aiming their weapons at the many people standing in the center of the main hall. In the blink of an eye, Kallen had activated the energy wings on her Guren and sliced through the Knightmare in front of her with them, splitting the enemy's device in half on the middle. At the same time, she fired the right arm as a slash harken, piercing it through another Knightmare.
It was at this point that the enemy had noticed the Guren, but they barely had any time to react. Kallen flew her Guren into the air, while sending a power surge through the right arm into the already pierced Knightmare.

"Enemy Knightmare spotted! Focus fire!" One of the enemies shouted.
"What the hell is that thing?"

"Get a taste of this!" Kallen grinned as she activated the Harken booster, and disappeared within the blink of an eye.

"It's fast!" One enemy exclaimed, before getting a mechanic arm attached to his Knightmare from behind, a power surge blasting through and practically melting his Knightmare from the inside.
Already now, there were only 2 enemies left for Kallen to take care of. Even though it had been 8 months since her last ride with the Guren, this was like a piece of cake for her. All it took for her now was to fire the two slash harkens from the shoulders of the Guren, rendering the remaining enemy Knightmares for demolished within a couple of seconds.

"You chose a bad time to act, idiots!" Kallen muttered to herself with a frown on her face, before activating the speaker communication system on the Guren.
"Everyone! We still can't be sure if there are any more threats, so I strongly advice you all to evacuate the building!"
Just like that, Kallen could make them believe that she was from the Britannian army. There were a lot of doubts though, considering many people had seen the Guren on the news a long time ago, under the Black Rebellion. But they didn't care about that, they all just wanted to get out, and so they did.

At the same time, a voice could be heard on speakers outside. Britannian forces had arrived. Even though Britannia was much better after Lelouch's plan, Kallen didn't fully trust them, so she decided that it was best for her to get the hell out of there. She headed back towards the hole in the wall that she had come through.

While passing through, she could barely spot a glimpse of white and gold, rolling into the main hall.
'What the hell is that doing here? Is it still him who pilots it? People are supposed to think he's dead!' Kallen thought, shocked to see the Lancelot again after such a long time. Brushing the thought of, she hurried over to the spot she had left Rivalz, finding him hiding behind a crate. She hurriedly opened the Guren, waving at him.

"Get your ass in here, we're leaving!" Kallen shouted, and Rivalz wasted no time to get in and sit in the tiny spot behind the pilot seat. He didn't even bother to ask any questions yet, as he as much as Kallen, wanted to get the hell out of there.

Kallen activated the Harken booster and flew them both out of there as quickly as possible, simply hoping that no one would see them.
'Like it even matters now, the civilians saw the Guren, they'll probably tell it to the Britannian forces.' Kallen mentally cursed to herself. It was too late now, anyways. Someone knew that the Guren was back, but they couldn't be completely sure that Kallen was in fact piloting it.

Shortly after, the Guren arrived at the hiding spot it had been standing in. It was a completely abandoned warehouse in the outskirts of town. Rivalz and Kallen climbed out of the Knightmare, and Kallen started pacing around.

"What was that back there?" Rivalz asked, seeming much more calm than before. Kallen didn't even turn to him, she just kept pacing back and forth.

(2*)"That, my friend, was a terrorist attack. Just plain luck that I happened to be there." Kallen said, looking as if she was thinking hardly about something.
"Shit! That Lelouch just has to be dead when we really need him!"

"Lelouch? What does he have to do with this?" Rivalz asked, confusion written all over his face.
"Lelouch is no good! Lelouch was bad!" He exclaimed.

"It's a long story, ok? Let's just say that old friend of yours would know what to do in the outbreak of a new terrorist group. Shit."

…

"And it has been reported that the assumed terrorist group was wiped out by a red Knightmare frame. This is all we've got from the case so far, and we will report back as soon as we know more."

The TV sounded, and the green haired girl smirked.
"Interesting." She muttered to herself, tightly holding onto her 'Cheese-kun' plush, which was almost like her trademark by now.
"But it is as you feared, isn't it?"

"…"

"Yes, indeed so." C.C retorted, sounding both serious and slightly amused at the same time.
"I guess we'll have to get going in not too long, then."

"…"

"Yes, I understand. Take your time."
C.C sighed before lying down on her back, her arms spread out on her sides.
"These past 6 months have been so boring. I'd gotten used to an exciting life, and then it all turned back to this boring existence. Hopefully, that will change soon, yes?"

"…"

C.C giggled a little closing her eyes.
"Yes, I do hope so."

…

Suzaku threw the Zero helmet down on his bed and started pacing around the room, distressed.
"So it broke this soon?" he cursed to himself, seeming both angry and disappointed. "Lelouch would not be happy about this."
Of course, they hadn't expected a complete state of peace to maintain forever, but this was even sooner than Suzaku had expected anything to happen.
"Let's just hope they're not up to anything bigger. I have to make sure Nunally is safe."

"Suzaku?" A gentle voice spoke over the communicator outside of Suzaku's door. It was impossible to get in without being let in from the inside, or having Suzaku's fingerprints. After all, no one could know about "Zero's" true identity.

Suzaku pushed a button that opened the door, and Nunally entered the room in her wheelchair. Suzaku had still not gotten completely used to her having her eyes open all the time. She could see now, after all.

"I heard about what happened. I can't really say I'm too good with all these warfare things, so I must ask you for help. I assumed that asking my brother, Schneizel, is unnecessary." Nunally said, concern in her voice.

"I'm honestly not sure what to do yet. We weren't prepared for this yet. Me, and the other generals, will need some time to think. We don't even know what to tell the public yet." Suzaku answered, seeming very distressed about the whole situation.

"Then take the time you need. I trust you more than anyone else, you know that." Nunally smiled at him, and Suzaku kneeled in front of her.

"Of course. It is my honor to be your guardian."
Nunally put a hand on Suzaku's head, closing her eyes.

"Thank you, Suzaku."

And so, that marks the ending of chapter 2. I'm feeling really good about this fic so far, and I have yet to reveal a few things.
Oh god, I honestly can't wait for the big surprises.
Until next time ~
