The End of the World was a world where the debris of the worlds taken by the heartless were sent. Heartless loved it there and waited in the shadows to destroy any unwary travelers.

Fortunately Sora and the others were very wary.

They burst into the final room of this bleak world. Ansem was there. Mia lay unconscious on the ground near him.

"Well I didn't expect you to come so soon." He sneered.
"SHUT UP! NOW GIVE MIA BACK!" Riku yelled.
"Ha ha! You know I just can't understand you people. Meet a female and you fall in love with her, take her away and you get mad. But Riku, you are too strong to succumb to your emotions like this. I will make you a king of all heartless if you agree to destroy Mia's heart."
"I would rather die than hurt her or any of my other friends!" Riku yelled.
"Hmm, what a pity."
"Before I cut your throat tell me this, why is it that when Mia came it felt like I was back to normal?"
"Because when you were taken out of Kingdom Hearts you lost a part of your heart inside. You lost an emotion."
"What emotion was that?
"Love."

Riku was stunned. So that had been the answer the whole time. Mia had restored his heart to him. That explained why he was now back to normal. Now it was time to get her back. He drew his keyblade.

"Wait Riku." Sora said stepping in front of him.
"Don't try to stop me Sora!"
Sora grinned. "Are you kidding? I'm fighting with you."
"So will the rest of us." Kairi said smiling. "We're all in this together Riku."
"How touching," Ansem laughed, "Friends again, just in time to be blown to bits by the forces of evil!"
"Remind me again why I decided to help?" Sora gulped. Kairi elbowed him in the ribs.

At that moment Mia stirred and sat up.
"Ah so you're awake. Excellent, now we can begin the ceremony." Ansem said yanking her to her feet.
Suddenly Mia whipped her hand into her pocket and pulled out a pocketknife. She slashed Ansem across the arm.
"ARGGGGGGGH!!!" He yelled. He struck Mia across the face and began to twist her arm.
"Leave her alone! I'll kill you!" Riku yelled. Sora and Tidus had to hold him back.
Mia winced as Ansem twisted her arm. Her knees buckled but he cruelly yanked her upright.
"You stupid little girl, don't you know I can crush you anytime I want to?"
Mia swung her foot and kicked him in the shin.
He hit her again and quit twisting her arm. He reached into his pocket and pulled out a dagger. It had bizarre symbols all over it and a jeweled handle.

"This is the dagger of darkness, all's I need is the leader of the pure-hearts to obtain its awesome power!" Ansem yelled. He held up the dagger. "Oh great powers of darkness! I offer my blood as a sacrifice! Devour it and bestow your awesome powers onto me!"
He gripped the dagger and dragged it across his wrist. Blood seeped from the cut.
A swirling cloud of darkness appeared overhead.
Ansem held up the dagger once again.
"I also offer you the blood of this pure-heart! Make her fuse with my darkness so that I may become invincible!"
There was nothing Mia could do to prevent it. Ansem made a cut on her wrist about the same size as his own cut.

The darkness seemed to be stirring. Suddenly it shot down into Ansem's cut and began to enter his body. But his hand still had a death-grip Mia's arm. She screamed and struggled to break free. Once the darkness was finished fusing with Ansem it would come into her and devour her blood.
"Hang on Mia!" Riku yelled. He broke free from Tidus and Sora and ran towards Mia. He yanked her free from Ansem's grip. The two of them ran from Ansem's side and back with the others.
"How bad is it?" Yuna asked taking Mia's wrist and looking at the cut.
"It isn't too bad," Mia said, "Just a little cut."
"Well, better safe that sorry. CUREGA!" Yuna yelled tapping the cut with her staff.
The cut instantly closed. There was no mark to show Ansem's work.
"I'm definitely going to have to remember that one." Mia said smiling.
"YOU MAY HAVE TAKEN THE PURE-HEART BUT THE POWER SHALL STILL BE MINE!" Ansem roared as the darkness consumed his body.
There was a rumbling sound. The entire cavern shook. Rocks fell from the ceiling blocking the exit.
And where Ansem had been there now stood a ferocious-looking monster. It had gigantic bat wings and horrible claws. It had had the same catlike golden eyes. It was completely made of shadow and darkness seemed to radiate from its body.

Mia put her hands over her head and sank to her knees. "No, no, NO!!"

"What's wrong Mia?" Lulu asked kneeling by her.
"The darkness is...calling me!" She cried.
Suddenly a dark swirling vortex opened up in the monster's chest. Mia screamed and was sucked into the horrible creature.
"MIA!" Riku yelled.
The monster threw back its head and laughed cruelly.
"NOW DIE, KEYBLADE MASTERS!"
An enormous ray of energy blasted from Ansem's hands and blew up the wall behind them.
"He's using Mia's power to increase his own!" Auron yelled, "If we're going to destroy him we'll have to get Mia out of there."
"I'll go." Riku said without hesitating.
"Fine, we'll fight on the outside. But remember, once you remove Mia from Ansem's core then he will start to self-destruct and you will only have a few moments to escape."
"Right." Riku said getting into running position.
"Go."
Riku ran forward. His heart was pounding inside his chest. He sprang forward and jumped into the closing vortex in Ansem's chest.

There was darkness as far as the eyes could see. He could hear sounds of fighting outside.
He heard Katie yell: "TAKE THAT YOU WINGED SPAWN OF SATAN!!!"
He could see Mia floating far towards the center of the beast. He flew towards her and scooped her up. Her eyes opened and she stared up at him.
"Riku, where are we?"
"We're inside Ansem. We've got to get out now!"
Suddenly there was a roar from outside and the whole place began to collapse.
Riku and Mia bolted for the vortex but it had sealed up.
"We're dead meat!" Riku cried.
"Riku?"
"Yeah Mia?"
"Do you remember what I said before? About not being sure of something?"
"Yes."
"Well, since we're going to die in a few seconds I guess I can me sure of something."
"Like what?"
"Like...I'm sure that I love you."
Riku stared at her and smiled. "I love you too Mia."

They kissed. Suddenly a bright shield of light formed around them. The monster was being destroyed but they were safe. Mia and Riku didn't notice any of this. They were lost in their own world.

"HEY YOU TWO!" A voice yelled. Mia and Riku were still kissing and hadn't noticed that Ansem was dead.

"Hey!" Wakka yelled. "The inside of the insane dark wizard is NOT a make-out place!"
Lulu rolled her eyes. "Wakka, they're 16, to them everywhere is a make-out place!"
Riku and Mia looked over at their friends and quickly stopped kissing and blushed.

"So is Ansem really dead?" Riku asked kicking part of the debris.
"Yes," Auron said nodding, "There is no trace of him left."
"Finally, all this horror is over." Sora said smiling, "Well, time to go back to Traverse Town."
"Can't we wait just a little bit?" Katie gulped.
"Why would you want to be in this awful place anymore?"
"I don't, but I'd rather be alive here than dead back in Traverse Town."
"Huh??"
"IN CASE YOU FORGOT CAROLYN IS GOING TO KILL ME!"
"She seemed pretty weak to me. A little too temperamental." Yuna said shrugging.
Katie stared at her in shock. "ARE YOU CRAZY?! Carolyn is the greatest fighter in the universe! She saves our world on a daily basis!"
"From who?" Wakka asked.
"A crazed scientist named Dr. Sloth who's hell-bent on conquering the planet. Although he's pretty stupid and screams like a girl he's still a threat."

"Hey a blitzball!" Katie said pointing at Wakka's weapon.
"You play?" Wakka asked sounding surprised.
"Well...I played it once or twice." Katie said.
"Here show us." Wakka said handing it to her.
Katie took a deep breath and tossed it into the air. Then she jumped up after it and kicked it with all her might. It shot forward and made a dent in a stone building.
"Holy shit!" Tidus cried.
