Chapter Five-The Unknown Keyblade

Riku held Kairi tightly as she cried in his arms. She hasn't stop crying since their return from Sora's home and she was blaming herself for Sora's action against them, blocking himself from the outside world.

The young sixteen year old tried soothing her, telling Kairi that everything will be fine and their problems will be worked out soon enough. However, Riku knows in his mind that Sora is done with them, after he made it a clear statement that he doesn't want them in their life anymore. Riku never thought their twelve year friendship would end like this. The bond was strong and it even showed during their adventures. Enemies tried to manipulate both their minds so they could fight each other to the death, but the bond couldn't be broken.

Even Xemnas witnessed their powerful bond and it ended his life.

However, this betrayal has done the damaged and cause the bond to shattered in pieces. Every fun memory they had was gone.

"R-Riku, I'm a b-bad person," Kairi stuttered as she continued to cry.

Riku shook his head and gently rubbed her shoulders. "You're not a bad person Kairi, everyone makes mistakes."

"No, this wasn't a mistake. What I've done can't be described and Sora will never be the same again because of me."

"Kairi..."Riku sighed, knowing it's no use getting through to her. When she feels she has done something wrong, it's no use trying to tell her she isn't the problem.

He knows that Kairi shouldn't be drowning herself for the blame. He should be the one suffering. He was the cause and the effect that got everyone thinking about themselves.

"Kairi don't put yourself through this. It was my fault in the first place. If I didn't do want have done to you, we wouldn't be in this mess."

Shaking her head, Kairi stood up from her bed and walked towards the window, her puffy eyes gazing outside the sunset. "It doesn't matter Riku," she said quietly. "Your fault or mine, we still hurt Sora, a friend who would never try to harm us." Turning back around, arms folded across her chest, she continued saying, "I think it's best if you leave Riku..."

Riku was stunned by her actions and opened his mouth to protest, but decided not to. He nodded and understood that Kairi needed to be alone right now.

"I guess...I'll talk to you later then." Riku stood up from the bed and Kairi nodded slowly. She turned back facing the window and then she heard the door shut from behind and sighed.

What am I doing? She thought.

"So, what do I have to do?" The young Keyblade master asked his imaged. His blues eyes following his every movement, as he circled around him.

Smirking, anti-Sora held out his hand and with a snap of his fingers, the two keyblades, Oathkeeper and Oblivion, appeared in front of Sora. They were levitating slightly above the ground. "The Oathkeeper and Oblivion keyblade..."Sora said quietly.

Exactly, Sora, those two blades are the most powerful ones in the world. The Oathkeeper is powerful on the light side, and the Oblivion, powerful on the dark side. When they are combine...they create a powerful keyblade, capable of destroying anything insight. Now watch closely...

Sora watched as the two keyblades came close together and then in an instant, they began merging withing each other, creating a white light in the process. Moments later, the light faded away and he opened his eyes from the blinding light.

As he looked up where the two keyblades were at, there stood only one keyblade levitating in the air. It was black and silver, two inches longer than an average keyblade, and the end of the blade was sharper than any other keyblade.

"What kind of keyblade is this? I've never seen one like this." Sora's eyes examined the new highly weapon and he admired its features.

It's the Unknown Keyblade, Sora. This is the most powerful keyblade ever!"

"The most powerful keyblade ever..."

Anti-Sora nodded. Yes it is. The Unknown Keyblade was only a myth and past keyblade warriors even tried to search for it. This keyblade is different from the other ones because normal keyblades choose their masters whether they have a strong heart for light or strong heart for the dark. However, they say whoever touches this keyblade will be its wielder forever and no other can wield it. Only its master can wield and those who possesses his or her genes.

Sora furrowed his brows, thinking about what anti-Sora told him. If he touches this keyblade, only he will possess it and no one else. Meaning, Riku won't be able to wield, whether if he has a strong heart or not. "So, if I touch this, I'll be the only one and its only master?"

Anti-Sora nodded once again. Sora, you are the first to witnessed it. Go on and feel it's power.

Sora did as he was told and he wrapped his hands around the handle, and suddenly he felt a felt flow of energy rushing through his body. The power he was feeling from the keyblade was unbearable. He never felt so much energy, so much power before. The other keyblades couldn't compare to the type of power his was feeling from this one.

Sora screamed as he tried to gain as much darkness into him, and afterwards he collapsed to his knees, his left hand holding the Unknown Keyblade, breathing heavily as dark aura surrounded his body.

The Unknown Keyblade will make you stronger as progress your journey of terror. The more chaos and havoc you cause, the more the keyblade absorbs it and gain energy from it. It will make you invincible. Anti-Sora reminded his host.

"So basically it feeds of destruction?" The brunette slowly struggled getting up and regaining his balance. He felt a little woozy since he wasn't use to the dark energy, especially one with so much power beyond he ever had.

Correct and theres a one more thing you need to know about this keyblade. Anti-Sora smirked

"And what is that?"

The heartless grinned evilly, as his golden eyes glowed with excitement. It kills humans as well.

"It kills...humans as well." Sora's eyes widened in shock. Keyblades weren't made to kill humans' right? They were meant to kill only heartless right? Then his eyes narrowed and a sickening smiled formed on his lips. "Perfect. They all need to suffer. So will Kairi and Riku. I'll make them scream and moan in pleasure all right. Then will see who's having the most pleasure," he hissed.

Anti-Sora was finally getting what he wants. If Sora keeps allowing the darkness to flow through his veins, and no time will he have Sora under his control and the world will feel they're wrath.

I can see that the keyblade is giving you the darkness. With me and you combined Sora, nothing will stand in our way!

Sora don't! familiar voice shouted.

Sora turned his head and saw Roxas appeared a few feet away from him. The nobody's blue eyes were filled with anger, yet sadness as he glared at Sora and his counterpart. He heard it all and felt Sora lingering into the darkness. He hoped it wasn't too late to change him back.

Sora, don't listen to him. He's trying to trick you. He wants to use your body as a host. Roxas said pointing at Anti-Sora. His blue eyes were glowing in anger.

Anti-Sora folded his arms and frowned. Now, Roxas, why would you say such a thing? The heartless titled its head.

Roxas gritted his teeth, his fist clenching as he tried to hold back his anger. He didn't want to wield out his keyblades and start a fight, but this other Sora was tempting him. Shut up! You've already cause so much trouble for Sora. He doesn't need any more. How dare you use his anger to control his fate?"

"He isn't controlling my fate, Roxas," Sora said defending him. "I've choose to fate for a reason. When I wield this keyblade and cause destruction throughout the worlds, they will feel my suffering and rage!" Sora eyes glowed bright yellow.

Looks like he's getting stronger by the minute. Anti-Sora said noticing Sora's eyes changing colors from blue to golden orbs.

Roxas ignored dark version of Sora's comments and continued speaking to Sora. Sora we can work this out. You don't need to end your friendship with Riku and Kairi like this. You are better than this.

The nobody tried getting to him, but the young keyblade master shook his head, and Anti-Sora laughed. He's not listening. He sang.

Didn't I tell you to shut up! Roxas had enough and summoned both the Oathkeeper and Oblivion. He tightened his grip on both blades and charged towards anti-Sora. As he lifted the blades over his head, while he jumped in the air, in a blink of an eye, Sora appeared blocking his path. The nobody paused his attack.

"Sora...what ar-" Unexpectly, Sora lashed an attack on Roxas, fortunately, he was able to jump back away from the attack.

Sora! What are you doing?! The stunned Roxas shouted. He never expected Sora to attack him. He knows this attack isn't from their recent battle they had with each other.

Sora didn't answer but narrowed his eyes and launched another attack. Roxas tried his best not to fight back and not try to hurt Sora. The Sora he knew wouldn't harm anyone unless he had to defend himself or save the world.

As their blades collided, Sora tried forcing the defensive Roxas on to the ground. Roxas' foot was slipping underneath him and he was trying his best to hold his ground. With a powerful shove, Sora was forced into the air as he back flipped. Roxas took this opportunity and he leap into the air, and was about to slice an attack on Sora, but he missed and hit only solid air.

Huh? Where did he go? Roxas shifted his eyes searching for Sora, who vanished in thin air.

Anti-Sora laughed in amusement as he watched Roxas baffled about Sora's whereabouts. He sensed where Sora was and knew it will be over shortly.

Sora suddenly appeared behind Roxas, smirking and cut Roxas from behind.

Ahhh! Roxas screamed in pain, falling to the ground. When he landed with a loud thump, his two keyblades disappeared and Sora landed on the ground, pointing the Unknown Keyblade inches from Roxas' face.

It's like I said Roxas, Anti-Sora said walking up beside Sora, arms crossed, grinning evilly. He has chosen his own fate and you couldn't stop him and neither will anyone else. His grinned then formed into a scowl and he turned to Sora. Finish him.

Roxas looked into Sora's now yellow ones, and saw no happiness like he has seen before. That Sora no longer existed anymore. This Sora shows emptiness, no sympathy, or any bit of guilt whatsoever.

Roxas was in disbelief that Sora already sealed his fate. He tried to convince Sora that this wasn't the right choice, but he failed.

So, is this it Sora... Roxas was breathing heavily, his body was beginning to fade away because of Sora's darkness was taking control. Is it...worth it...

The keyblade master narrowed his yellow eyes at his weakened nobody. "Yes..." he responded coldly and then held his keyblade up, preparing for the final blow.

Kairi shot up from her peaceful slumber, clutching her chest, where her heart was beating rapidly. She felt her nobody, Namine, hurting in pain. She sensed something was wrong.

"Namine, are you okay?"

Kairi, i-its...Roxas...

"What about Roxas? Did something happen to him?" Kairi knows Namine can feel Roxas anytime and tell her how he's doing. If something happened to Roxas, then something must be wrong with Sora.

Kairi, I can't sense his presence anywhere. Roxas...is gone!
