A/N: This will be my first Rated M fanfic

A/N: This story was inspired by Inulover4eva's "Island of Secrets". This story is rated M for it will include lemons, violence, and explicit language. The pairings are Kira X Cagalli (Yes, that means it will involve incest) and it implies Athrun X Cagalli a bit. Don't like, don't read. KIRA X CAGALLI FOREVER!! Oh, I don't hate Lucas. R&R

Disclaimer: I do not own Gundam Seed, but God I wish I did…

Kira: ….

Cagalli: ….

Riaken: What's wrong with you two?

K&C: …You're a sick fuck…

Riaken: Then why are you two reading the story?

K&C: blush

"KIRA!!" yelled a teen male in a dark red jacket. His dark blue hair blowing in the small breeze that made its way in to his cockpit. He moved a handle forward as it's thrusters activated. On his screen resided "G.U.N.D.A.M". His Gundam dashed forward, charging at another in front of his own.

"ATHRUN!!" yelled a voice from the other Gundam in front of him, coming from the cockpit. The pilot, who was identified as Kira by the dark blue haired teen-Who had just been identified himself as Athrun- pulled back a handle, and the giant machine fired a green beam from his rifle. Athrun threw a control forward and another back, and almost instantly, the red Gundam pulled a barrel roll, getting away with a blow to the arm., but not before returning fire and nailing Kira's Gundam, the Freedom, in it's knee joint. "Tch, dammit!" he said as the Freedom drew a beam saber and dashed forward.

The red Gundam, the Justice, barrel rolled again, dodging the saber and then pulling out his own, jamming it in to the Freedom's side. The Freedom preceded to pull away, springing up and throwing a kick to the other's head with it's good leg. As the kick neared the point of connection, both Gundam's turned grey, and stood still.

"Battle over!" a computer declared as the cockpits of both pilots slowly opened., and Kira and Athrun emerged from the Freedom and Justice respectively.

"Looks like I win!" Kira said, trailing his fingers through his brown hair, sighing loudly.

"Don't kid yourself!" Athrun replied, pointing to the Gundam's, still in the position they left them. As Kira looked on, he noticed the Justice was pulling something from it's legs, most likely a dagger. Were the kick continued, the leg wouldn't be there.

"Hmmm, sneaky Athrun. Wasn't expecting that." Kira laughed as Athrun joined in. As they exited the room, Athrun was caught in the arms of a blonde, who looked somewhat like Kira, if not exactly alike.

"C-Cagalli!" Athrun got out, being caught off guard and falling over on his back.

"YOU'RE AN IDOIT!!" she yelled out. "You promised to meet me at four, and now it's five thirty seven you jerk!" she replied as Kira laughed slightly. Cagalli noticed him and jumped up, tackling him in to a wall. His back smashed in to it, hard.

"Oww, what the hell Cagalli?"

"You could've hurt Athrun!" she yelled back, punching him in the arm. She then helped Athrun up as he laughed. She then kissed him deeply. Kira smiled and then looked at the floor, sighing.

"I'll…see you guys later…" Kira said as he walked off down the hall, heading to his room. The pair behind were left confused.

"What's his problem?"

"I don't know…" Cagalli replied to Athrun as she watched him disappear from sight. "Athrun, I'll be right back!" she said leaving his arms and running down the hall.

"B-but Cagalli! What about our pla-"

"He's my brother, I have to!" she said, disappearing after Kira, out of Athrun's sights.

In his room, Kira was laying on his bed. He started blankly at the ceiling. He started to see the fading image of Flay and it's place appeared the fierce blonde that was his sister. He rubbed his eyes. "…Cagalli…why do I…" he sighed a bit as his door flew open.

"Kira…" said a soft voice as Cagalli stood in his doorway.

"Cagalli!" Kira yelled as he leant up to look at her."

"I thought you and Athrun had pla-"

"I came to check on you. You're my brother, and I'm concerned." She said as she walked over and sat on his bedside. He moved over next to her, but looked at his hands. She grabbed them and looked him in the eyes as he blushed. "Kira, what's been going on lately?" she said hugging him tightly. "You're worrying me…"

Meanwhile, Athrun had entered his own room, playing with the Haru on top his desk. He wondered about Lucas, as there was then a knock on his door. It flew open as a member of the Arcangel approached him.

"A-Athrun Zala? I'm here to deliver a letter!" she said as she handed it to him, and then left. He looked at it and noticed the seal on the letter, his eyes widening.

"PPLANT?!" he said as he proceeded to open the letter.

Kira and Cagalli left his room a bit later, both blushing.

"Cagalli…I'm sorry…" he said looking away.

"I-It's fine…I'd better find Athrun." She said as she started to walk off, but was stopped when some staffers running by.

"Hurry, we have to stop the Justice!" one yelled as they made a left, the two twins following upon hearing 'Justice'.

In the hanger of the ship, a red Gundam was making it's way toward the Catapult.

"LET ME HEAD OUT!!" Athrun yelled from the cockpit, meeting heavy resistance as he tried to escape. Kira rushed up a flight of stairs o try and reason with Athrun, only to be blown off the ledge by the Justices busters as it escaped, sending Kira flying backwards. He would've died were it not for Cagalli grabbing his wrist. She pulled him up and he fell on top of her, both breathing heavily, they blushed as they pulled away from each other, Cagalli finding a letter on the floor, picking it up to read it. Her eyes widened.

"Cagalli, is something wrong?" Kira asked concerned. She looked at the floor, and tears started to fall from her eyes.

"I'm…I'm fine!" she said running off. Kira went to grab her, but she was gone.

"Cagalli…"

A bit later, night hit. They were over the ocean, so it was easy to tell. Everyone was apparently fast asleep, except for the fiery blonde know as Cagalli. She wondered off to the hanger, the letter from before still in her hands. She slowly began her trek to the Freedom, and as she entered the hangar bay, she could slightly her snoring, but ignored it. She popped open the cockpit, and a vain appeared on her forehead. Kira was asleep in the cockpit, birdie on his shoulder.

"…Dammit!" she whispered as she began to sneak away.

"Cagalli? What the hell took so long? Are you coming or not?" Kira said rubbing his eyes as birdie flew away.

"Coming? What do you mean?" she mused as she laughed uncomfortably.

"I know you want to get Athrun, and I knew you'd be willing to take the Freedom to do it, but I won't let you go alone!" he said grabbing her hand and bringing her to the cockpit. "I already disabled the security system, but they'll be back on in the morning, so let's get moving befo-" he was cut off by a loving embrace from a blonde sister.

"Kira…thank you!" she said as tears fell from her eyes. Kira was a little shocked, this was one of the only times he'd seen Cagalli cry aside from when her father died.

"C…Cagalli…" he said as she reluctantly left his figure. "I'm sorry…let's go…" she said as she sat on his lap, the cockpit of the Freedom closing as it activated, taking off.

They spent hours searching for the lost member of their group. It was about eight thirty P.M. when they left, and it was now seven thirty seven A.M. They were tired, but wouldn't stop.

"Kira…do you think he's alright?"

"Don't worry Cagalli. It's Athrun we're talking about. He'll be ju-AHHHH" he yelled as the Freedom started to shake rapidly. It was hit in the back by a beam. A battle was going on, and in the middle, hovered the Justice.

"ATHRUN!!" yelled the twin's as they dashed to him. Athrun was taking down a horde of Skygraspers left and right when he noticed the Freedom's approached.

"KIRA, LOOK OUT!!" Athrun yelled as a beam hit the Freedom's thrusters. They were pretty high above the ground, and falling could be fatal. Kira began to channel all the power to the main thrusters as a mobile suit suddenly appeared a top a rock formation. It was blue and grey and held a large cannon.

"SAY GOOD NIGHT, BITCHES!!" he yelled as he fired it, a large beam hit the Freedom, sending him and Cagalli hurling towards the ocean. The cockpit flew open, and Cagalli who wasn't secured, flew out, but was caught be Kira.

"CAGALLI!!" he yelled, holding on as tight as he could.

"KIR-AHHHHHHH" she yelled as they both flew out of the cockpit of the freedom. They flew towards the ocean below, but not before Kira grabbed her and wrapped his hands around her waist. She did the same as they suddenly hit the water. He let go by accident, and she tried to hold on, but the impact was to much for her, and she let go as well. He threw his hands out to grab her, but was running out of air. He tried to grab her, but was losing consciousness. He quickly swam to the surface, and got ready to swim back down, but was knocked back by a large wave, completely losing consciousness at this point. His vision was fading, and he could see the Cagalli in the distance.

"Ca…ga…lli!" he got before everything went black, and everything went silent…
