The four arrive in the chamber where the keyhole is. The remaining princesses of heart are standing by the keyhole.
"Belle" yelled Beast. He walks over to her and they both hug each other.
"We're trying to hold the darkness that's seeping out the keyhole back" said Jasmine
"We won't be able to hold t for long" said Alice
"Don't worry guys" said Sora we can take care of it.
"We're counting on you" said a girl with black hair and a blue and yellow dress.
Sora makes his way to the Heartless emblem. Sora, Donald, and Goofy jump into the emblem. There they are greeted to a giant animal like Heartless with big teeth and small yellow eyes, a horn and some tusks. The three of them prepare to fight.
Meanwhile Aimala manages to make it to a heartless world just beyond Hollow Bastion. The entire world is crawling with heartless. Aimala sees a light in the very back glowing brightly. She slowly makes her way to the light. Heartless start appearing and Aimala tries to control them. The heartless don't appear to be listening to what she is saying. She realizes that her power must be too weak to command them. She summons her staff and slowly walks to them. The heartless strike at her but she manages to knock them out with her staff. With each passing fight she feels herself getting weaker. Despite this she presses on. She comes to a giant Heartless similar to the one Sora is fighting and takes a battle position. The heartless strikes at her with its claw. She dodges it and yells, "Thunderga." Lightning strikes the Heartless but it keeps going. One of its strikes manages to hit Aimala. She is knocked back but still alive. She gets on her feet and does a series of Fire, Blizzard, and Wind magic to slow it down. The heartless still charges at her. She dodges the attack and yells "Zero Gravity." She immediately starts floating in the air. She release the magic and lands on the heartless' back. She then uses her staff to strike the horn. It appears to be the weak point. The Heartless roars in pain and Aimala yells, "Thunderga." Lightning strikes the horn and the Heartless is defeated. She crashes on the ground feeling extremely exhausted. She gets on her feet and makes her way deeper into the world.
Back in Hollow Bastion, Sora and the others defeat their heartless and Sora locks the keyhole. He walks outside the emblem and Leon's group is there to congratulate them.
"What are you guys doing here?" asked Sora
"We came in Cid's ship" said Yuffie
"This is our childhood home" said Aerith "We wanted to see it again."
"It's in worse shape than I feared" said Leon "It use to be so peaceful."
"Don't worry" said Aerith "If we defeat Ansem all will be restored including your island."
"Really" said Sora. Aerith nodded
"But that means we have to say goodbye" said Yuffie
"Once the worlds are restored, they'll all be separated again" said Aerith
"Everyone will go back to where they came from" said Yuffie
"Then I'll visit you guys in the gummi ship" said Sora
"It's not that simple" said Leon
"Before all this you didn't know about the other worlds" said Yuffie
"Because every world was isolated" said Aerith "Impassible walls divided them."
"The heartless destroyed those walls" said Yuffie "But when the worlds return so will those walls."
"Which means the gummi ships will be useless" said Leon
"So you're saying we'll never…?" said Sora
"We may never meet again, but we'll never forget each other" said Leon
"No matter where we are, our hearts will bring us together again" said Aerith
"Besides, I couldn't forget you even if I wanted to" said Yuffie.
"What's that suppose to mean" asked Sora
They all laugh.
"Sora!" says Belle as she walks in with Beast. "There's a very powerful darkness growing far away from here. It may be where Ansem is.
"We can take the gummi ship and deal with him" said Sora
"Be careful" said Beast.
"I will" said Sora
Back in the heartless world, Aimala is barely holding on. The Heartless are endlessly attacking her. She barely manages to win each time. She finally gets to a door. The door looks fancy like it belongs in a castle. She slowly opens the door and walks through. Inside were what appeared to be the islands that Sora, Riku, and Kairi were from. The island seemed broken up and partially destroyed. It also seemed to be floating in mid air. Aimala sees Riku standing on the beach. She walks up to him.
"So you made it" said Riku in Ansem's voice. Aimala jumps back. Riku turns around to face him. "Surprised? Nothing like a reunion of friends even if the friends are traitors."
"What did you do to Riku?" asked Aimala
"I told you, His heart is gone. I've taken over for him. It's really a shame. Tricking him into accepting me was fairly easy thanks to Sora. To think that Sora's need to help others would drive Riku to abandon him and seek out power. And he thought you were weak."
"Riku isn't weak."
"No of course he isn't he wouldn't have survived as long as he did if he was. And clearly I underestimated your strength as well. To think that my other self would take your heart away from you means your power is worth more than what I have right now. Maybe I should have chosen you as my vessel instead of Riku. Taking Kingdom Hearts would have been much easier that way."Riku starts walking around Aimala. "When you fully accept the darkness you surpassed that of even your mother and father's power combined. You were able to defeat Sora with this power. Had I not stopped you I'm sure Sora would be dead now. It's funny how Sora is the key to everything isn't it. He wasn't even meant to have the keyblade and yet it chose him; and with that keyblade he brought the death of all those you love. Even worse is the fact that Sora valued his new friends more than his old ones. Sora is the real enemy here. Don't you think?"
"Of course he is. Once I'm done with you he's next."
Riku laughs. "Do you really think that you have the power to defeat Sora now? You are barely able to stand. As you are right now Sora will walk all over you."
"You're wrong I can defeat him. I will defeat him."
Riku then frowns. "Too blinded by revenge to see the truth. Too ignorant of your own weakness to notice the scale of power between you two." Riku then transforms into an older man with silver hair. He wore a long black coat with white gloves. He had an open white shirt on with black plants and boots. The heartless symbol is tattooed on his chest. "I guess I'll have to show you just how weak you really are." He summons a giant demon-like monster behind him. He also starts floating in the air and crosses his arms. He smirks at Aimala who get ready to fight.
