Aqua: "Oh, so your name is Kasai? What a pretty name."

Young Kasai: "Thank you."

Riku: 'Weird, why do I feel this way? I'm almost positive that I've never met this girl in my life, but I'm starting to feel like I know her.'

Young Kairi: "Hey, maybe the other Sora told this one about it."

Riku: 'Now that's interesting.' "Other Sora? You mean you've met another Sora, Kasai?"

Young Kasai: "Uh-huh, but he wasn't as old as this one." Young Kasai points to Sora, "He was the same age as us." Young Kasai wrapped an arm around Young Kairi.

Riku: 'Hm, I have a hunch.' "Out of curiosity, did you meet another Riku too?"

Young Kasai: "Yeah, how did you know?"

Riku: "Just a lucky guess. Excuse us for a second." Riku practically drags Sora to the other end of the room, away from the girls. 'So she does know us, there's only one way to find out for sure.'

Sora: "Riku, what is it?"

Riku: "Sora, do you still have that keychain?" Sora nodded and handed Riku the keychain.

Sora: "What do you want with it?"

Riku: "Well it worked before, I want to see if it can work again." Riku made his way back over to the girls. 'I sure hope this works.' "Kasai, can you do me a favor and hold this for a second." Riku hands her the keychain.

Young Kasai: "Oh okay, but what for?"

Riku: "I just want to see if something happens." Young Kasai takes the keychain, which starts to glow again, but not as brightly as before. 'Good, I hope this works.' She eventually gave it back to Riku. "Thank you."

Riku and Sora both help the keychain in their hands, letting their old memories come back to them. They saw Destiny Islands, back when they were really young, everything as they remembered it. Then they saw the secret spot that they and their friends use to draw pictures. They saw Sora and Kairi drawing each other on the far end of the wall. This confused Sora because he remembers this memory clearly, as if it was yesterday, but it shocked Riku who saw something Sora didn't.

Sora: "What is it Riku?"

Riku: "Look at her left arm." Sora did so, and noticed that there was a faint mark on her arm, one that looked like a heart. Sora and Riku seemed to have the same idea. "Hey girls, do you think you can do us another favor."

Young Kairi and Kasai: "Sure."

Riku: "Can you show us your left arm? Both of you?"

Young Kasai: "Man, you guys sure do ask a lot of weird questions. Hehe." But the two girls did so, showing their left arms to them. Kairi's arm had no marks whatsoever on it, while Kasai on the other hand had a faint mark on it, one that looks like a heart. "Is something wrong?"

Riku: "No, nothing's wrong. Thank you." 'Strange, all of these years Sora thought it was Kairi who drew that carving of him, but…was it really Kasai?

Aqua: "Well, we'd better get going. I hope we'll see you around someday."

Young Kairi: "Me too!" The young Kasai said something, but it was too faint for anyone to hear it. Soon, everyone left the castle.

Riku: "Aqua, you know what happened to us, don't you?"

Aqua: "Well not exactly. I know what happened, just not how."

Sora: "Wait, you knew? Since when?"

Aqua: "Since we went to see Merlin. He didn't seem to know you guys at all, but from what you said, you knew him. I thought that was suspicious, and I had to follow a hunch. Once Sora suggested that we should go to the castle, I thought that would be a great place to see if what I thought was true. Sure enough, it was."

Kairi: "So, what exactly happened to us?"

Aqua: "Well, I don't know if this is true or not, but I'm thinking that the items you got from those three somehow teleported us to the past."

Kairi: "What? How are we suppose to get back home?"

Aqua: "I'm not sure." Riku noticed that there was something in his pocket as everyone else was talking. It looked like a note. Riku first read it to himself before he told everyone else about it.

Riku: "Hey guys, I think you'd better read this." Everyone walked over to Riku to see what the note said:

"Hi everyone, sorry I have to give you something like this in order to talk to you, but I don't want to worry my little sister. I know who all of you are, and don't worry, I know how you all can get back home. And don't look so surprised, I may be 5 buy I know a lot more than you might think. And don't try to think of how I wrote this, you'll just give yourselves a headache. Anyway, use the keychain you showed me and sis. That's what got you here, it'll get you back home. Just think of home, and you'll be back where you belong. Trust me I know what I'm talking about. Oh and Kairi, I'm sorry you forgot about me…that's gonna cause everyone a lot of pain later on. ~Kasai"

Riku: 'I wonder what she ment by that. She seems to know a lot more than she's letting on, and I doubt a 5 year old could write this, something doesn't add up.' The gang started to make their way back to Merlin's house to get Kasai, who still lay on the bed undisturbed.

Merlin: "Ah, so you're back. Good thing too, I wouldn't want her to wake up with you guys not here again."

Sora: "What? She woke up?"

Merlin: "Why yes. Not too long ago. Poor thing barely had any energy at all, she was barely able to sit up. I don't even think she knew where she was, her eyes had absolutely no light in them. When I asked her what happened, she said that she didn't want to talk about it."

Sora: "Oh…"

Riku: 'Hm, no light in her eyes? Does that mean she is rejecting the light, or she won't accept it? She keeps giving me something to think about, and the only way I can get answers is from her.' Aqua was about to pick up Kasai in order to move her, when Riku stepped in. "Don't worry I got it."

Aqua: "Are you sure?" Riku nodded and picked her up. She seemed to twitch slightly at the contact but she didn't wake up.

Riku: 'Hm, I wonder if she'll wake up soon.' They all soon walked to the outside to see if what the young Kasai said was true. Each one of them placed a hand on the keychain and thought about home, but nothing happened.

Sora: "Great, it didn't work. Now how are we suppose to get home?"

Suddenly, Kasai's eyes opened, and everyone was ready to fight her off if they had to, but that wasn't the case. By this time, everyone except Riku let go of the keychain, and soon Kasai joined him. She didn't seem to be fully conscious, so everyone let their guard down, but they didn't expect the keychain to start glowing brightly as soon as Kasai touched it. Sora, Aqua and Kairi scrambled to come back into contact with the keychain, fearing that if they didn't they would be left behind. They made it in time and were all teleported back to their own time. The keychain gave off a blinding light, causing Riku to shut his eyes tight. He began to open them again when he heard someone shouting.

Kairi: "Sora! Sora please wake up!" Riku opened his eyes to see Sora passed out on the ground.

Riku: "What happened?"

Kairi: "I don't know, he just passed out! Sora, please wake up!" Kairi was shaking Sora violently trying to wake him up, but no luck.

Aqua: "Kairi stop, if you keep doing that you'll severely injure him."

Kairi: "He may be injured now! We have to wake him!"

Riku: "Kairi he'll be okay, Sora's not the guy to go down without a fight." At the mention of Sora's name, Kasai's body twitched again, and again she didn't wake up.

Aqua: "He's right, I'm sure he'll wake up soon." Kairi nodded in defeat. "Now what're we going to do with her." Aqua pointed to a still unconscious Kasai.

Riku: "Sora's told me time and again that he has friends here, maybe they can look after her."

Aqua: "Alright, why don't you go and see if they can watch after her and we'll stay here and watch after Sora until he wakes up."

Riku: "Alright." Riku left Aqua and Kairi behind as he left with Kasai to the castle, where he assumed Leon and the gang were. Luckily for him, he was right, but since he never really met any of them, he had to introduce himself, something he wasn't really good at.

Yuffie: "Oh hi! I don't think we've met, I'm Yuffie!"

Riku: "H-hi, I'm-"

Yuffie: "Oh what happened here? Is she alright?"

Riku: "I-I think she's fine but-"

Yuffie: "Aerith! Come here! I think this girl needs some help!" In the near distance approached another girl.

Aerith: "What is it Yuffie? Oh hello, I don't think we've met. I'm Aerith." Aerith approached Riku and Kasai to see what was wrong with her, hopefully heal her.

Riku: "N-nice to meet you, but all I wanted to ask was-"

Yuffie: "Oi! Leon! Cid! Tifa! Come out here!" Leon, Tifa and Cid came out of the castle, thanks to Yuffie's constant yelling. Kasai's slowly started to open, but Riku didn't seem to notice. Tifa approached Kasai and looked over her along with Aerith.

Cid: "Jeez, what's with all the racket out here?"

Yuffie: "I think this girl needs some help!" Leon walked up to Kasai to see what happened.

Leon: "Who are you?"

Riku: "Riku. Sora's friend."

Yuffie: "Oh, you know Sora? Why didn't you say so?"

Riku: "I would have if you gave me the chance."

Cid: "Hoooey, he got you good."

Yuffie: "Oh shut up Cid!"

Leon: "So what can we do for you?"

Riku: "I was hoping that you guys could look after her for a while. She could really use a place to rest up."

Aerith: "Why yes of course, that's okay right Leon?"

Leon: "Yeah sure, why not." Riku handed Kasai's lifeless bodyto Leon, and was about to leave when he noticed her eyes shoot open.

Yuffie: "What's wrong with her?" A cloud of darkness started to surround Kasai.

Aerith: "Leon, you have to get away from her!" Leon quickly dropped Kasai and got as far away from her as possible. She managed to land on all fours, so she wasn't hurt.

Riku: "What happened?"

Leon: "I don't know, but I don't think we're going to find out anytime soon." Leon summoned his Gunblade, ready to fight against Kasai.

Kasai's body started to shake with anger as she raised to her feet. Once she was standing on two legs, she shot a death glare at Riku, that caused her eyes to turn bright yellow. Without warning, Kasai broke out in a light speed sprint and quickly was face to face with Riku. Before she could attack him, Tifa came out of nowhere and punched her square in the face, causing her to fly back a few feet.

Riku: "Thanks." Tifa couldn't respond, because she clutched the hand she used to punch Kasai with, shaking after seeing it was slowly turning black.

Tifa: "Wh-What's happening?" Aerith raced over to see if she could help Tifa heal her hand, but before she could get close to her, a large Darkness energy ball blasted Tifa back until she hit the outside wall of the castle. Tifa had enough energy left to stay conscious, but she had to kneel over in pain. Aerith quickly made it to her, but not before Kasai started to make her way over to them. Riku saw this, but didn't have enough time to react before she was within shooting distance of the two. Luckily for them, Cid managed to set him self between the two in order to block, but he was out of luck. Kasai latched onto Cid's heart and viciously ripped out something causing Cid to drop to his knees and fall unconscious.

Leon: "Yuffie! Go get Sora, we could use his help!"

Yuffie: "Right!" Yuffie raced away from the fight, but not before Kasai tried to stop her. Luckily, Leon was fast to attack her from behind and make her focus her attention onto him. While she was distracted Riku tried to sneak up and also attack her from behind, but she was onto him, and quickly dodged him. Riku and Leon were now standing side by side, trying to think of a way to get her to stay still. Leon thought of an idea, and went over it with Riku.

Leon: "Hey, Riku was it? Do you know the spell 'Gravity'?"

Riku: "Yeah, I learned it a while ago."

Leon: "Good. Cast it on her, and we'll both attack her with everything we've got."

Riku: "Sounds good to me." Riku quickly casted Gravity onto Kasai, causing her to temporarily to lose control of her legs, making her a sitting duck. Leon and Riku took this chance to close the gap between them and her, using all of their strength to slice through her, hoping that was enough to make her fall.

Voice: 'Sorry, that won't be enough.' Riku thought he was hearing things, as he turned around to see Kasai was still standing, not even looking like she was injured. She turned to both Riku and Leon, giving them another taste of her death glare.

Leon: "Geez, does this girl ever take a break."

Riku: "We don't have time to find out, just keep attacking." Both of them tried to double team Kasai, Leon shooting a fireball at her as a distraction with Riku running up the side to her blind spot. But Kasai didn't fall for it, she effortlessly redirected Leon's attack so it attacked Riku instead and that it did. Riku was already weak from Kasai's previous attacks that Sora didn't see, but he wasn't one to give up easily and took the hit and launched himself for another attack. Kasai just looked up at him, and simply dodged it, running straight for Leon.

Riku couldn't pick himself up in time so he was of no help to Leon. Leon tried to block it, but he didn't have enough time. Kasai ran up to Leon and quickly knocked Leon out with one powerful attack. When Riku regained his footing, he raced toward Kasai, ready to do anything to make her stop. Kasai dodged every single one of Riku's attacks, never letting him get close to hitting her. Once she saw an opening, Kasai quickly and painfully attacked Riku's heart, latching onto something that was connected to it. Soon enough, she ripped the part out of Riku's heart, causing him to instantly lose consciousness. As he slowly drifted out of this world, he could only hear Sora's voice, filled with anger.

Sora: "Kasai!" With that, Riku was out. He no longer knew what was happening in the world of the living as he thought that he would soon be one with the dead. Then, as a sort of way to keep him awake, Riku heard voices. They were distant and faint so he didn't know what they were saying. Soon though, the world he was in now turned from black to light in a flash, as he was now in a new world. Riku saw Destiny Islands, it was sunset as three kids were hanging out by the paopu fruit tree.

Young Kasai: "The sunset is so beautiful."

Young Riku: "Well, I don't know how you can see it. What, with your eyes and all."

Young Sora: "Riku! You shouldn't say things like that!"

Young Riku: "What? It's true."

Young Sora: "Well you still shouldn't say things like-"

Young Kasai: "Well he is right." Both of the young boys looked at Kasai. "I haven't been able to see anything on my own. I've had to use the help of other people to see."

Young Sora: "What do you mean by that?"

Young Kasai: "Ku-ku, look at something, anything at all. But make sure it's something I wouldn't think of."

Young Riku: "I really wish you would stop calling me that."

Young Kasai: "Oh I'm sorry. So did I just imagine me falling of that bridge right over there." Young Kasai pointed to the nearby bridge that Young Riku made her fall off of in an earlier vision Riku had, making young Riku scoff as a response.

Young Riku looked around the island, and chose something of interest to look at. Kasai closed her eyes, and when she opened them up again, they were the same color as Riku's. "You looking at the bird's nest that is resting on top of that cocoanut tree over there." Young Kasai pointed to the tree that was a good distance behind them.

Young Sora: "That's amazing! How did you do that?"

Young Kasai: "I'm not really sure, I just know that whatever whoever I'm with sees, I'm able to see it too."

Young Riku: "That must suck. Having to rely on others if you want to see."

Young Kasai: "I will admit that I don't like having to rely on others, but I'm grateful I have people like you guys to be with. So thank you." At those final words, the world Riku saw began to fade, and soon it disappeared completely, leaving Riku back in the world of darkness. Soon, Riku was slowly drifting back into unconsciousness, but if he did that here, he would never wake up.

Before he could drift into sleep, he heard a soothing voice, but it wasn't the kids he heard before in his past memories. The voice was…calm, and majestic, almost hypnotizing.

Once in a while

You are in my mind

I think about the day s we had

And I dream that these would all come back to me

If only you knew every moment in time

Nothing goes on in my heart

Just like your memories

How I want here to be with you

Once more

Riku slowly opened his eyes to see where he was. He looked around and only could a field of nothing but lilies as far as the eye could see. Each one was blooming with life, as they majestically flowed along with the wind (1). Riku looked around to see if he could find the owner of the voice, when he noticed a large Sakura tree. At the base of the tree sat a girl, who seemed to be holding something. The girl looked as if she didn't notice Riku as he got up and walked over to her.

You will always gonna be3 the one

And you should know

How I wish I could have never let you go

Come into my life again

Oh, don't say no

You will always gonna be the one in my life

So true, I believe I can never find

Somebody like you

My first love…

Riku: "That was a nice song." The girl looked up to Riku, who now had a better view of what she was holding. She was holding a dark, energy ball that resembled a heart. After a short amount of time, Riku realized that the girl was Kasai, and summoned his Keyblade, ready to defend himself. "Who are you really, and what is that in your hand?"

Kasai: "Oh, I don't think we officially met. I'm Kasai."

Riku: "I know who you are. What is that in your hand, and how do I know you?" Kasai stood up, Riku took a step back, ready for anything she might throw at him. Kasai did something unexpected, she handed Riku the energy ball.

Kasai: "Here, I'm sorry. This is really yours. I had no right to take it."

Riku: "Well what is it?"

Kasai: "It's your darkness. You saw me earlier, I wasn't in my right mind then. Sometimes I just lose control, and when I'm in that state I…I steal whatever darkness I can." Riku summoned away his Keyblade, he knew that this wasn't the same girl he fought earlier.

Riku: "So, that darkness…was in my heart?"

Kasai: "Yes. The shock from the lose caused your body to go into unconsciousness. I'm actually surprised that you're able to stand now. You require much of you energy from you darkness, and when you lost it, your heart couldn't take it. You need to take your darkness back, or else your heart won't be able to take it and eventually shatter." This was enough to convince Riku, as he took back his darkness.

Riku: "So who are you? How do I know you?" Kasai just looked down.

Kasai: "I don't know what you're talking about."

Riku: "Yes you do. You were with me and Sora on Destiny Islands. So what happened? Why couldn't I remember anything about that before now?" Kasai never raised her head. "I promise I won't get mad, I just feel like a part of my life is missing and I want it back." Riku placed a hand on Kasai's shoulder, causing her to look up at him.

Kasai: "I-I can't tell you. I don't think I can take it again."

Riku: 'Again.' "I promise, nothing you say will change who I am right now."

Kasai: "Okay." Kasai place a hand on Riku's forehead, seeming to give Riku back his old memories. He was once again back at Destiny Islands, he was on a boat making his way to the island, Sora was apparently already there. Once he tied his boat to the dock, he noticed Sora and what looked like Kasai hanging out around the Paopu tree. Young Riku raced to the tree to see Sora on the ground, clutching his arm, and Kasai was standing above him.

Young Riku: "What did you do?" Young Riku ran over to Sora to see if he was alright. His shirt was torn at the sleeve, and his eyes were shut tight because of the pain. Kasai didn't answer. "What did you do to Sora!"

Young Kasai: "I-I'm sorry I-I didn't mean to…" Young Riku got up and made his way over to Kasai.

Young Riku: "You're a monster! You think you can do whatever you want!" Young Riku grabbed Kasai by the collar of her shirt. "You think your pity routine will work forever and that no one will ever talk back you. Well that's not going to happen here. Hurt my friends, and you get hurt back!" Young Riku threw Kasai to the ground, hard. Hard enough that he could have sworn he heard a crack. Kasai didn't move, ready to take whatever else Riku had to throw at her. "You just ruined a good thing. Don't think that you are EVER welcome back here! You may have been our friend before, but not anymore. I don't to you ever again, you got that! I wish we never met you!" Kasai just nodded.

Young Kasai: "I understand. And if that's what you truly want…"

Young Riku: "It is."

Young Kasai: "…Then it should be right if I honor that. It'll be like you and Sora never met me." Young Kasai got up to her feet, and that was the end of the memory. Riku was brought back to reality, Kasai still standing in front of him.

Riku: "What do you do? All of those years ago…"

Kasai: "Sora was mad at you, for being so late coming to the islands, saying things like, 'Riku, that jerk! He made us wait the whole day for nothing!' and because of that…I lost control and…well you saw what happens to me when I lose control."

Riku: "Well then why did you tell me? I'm sure I would have understood."

Kasai: "What was I suppose to say? 'I thought you guys should know that if you get mad near me and I'll try to kill you?' That wouldn't help out at all!" Kasai started to cry, turning away from Riku. "Besides, you guys rarely fought in front of me. And when you did, it wasn't anything major, so I didn't have to worry about it. So I thought it would okay just to keep that a secret. Anyway, there's no way to change it now, so let's just forget about it." Riku thought that was fair and dropped the subject.

Riku: "So why can I remember these things now? After all these years…"

Kasai: "Unfortunately at the time, I didn't know how to use magic well, so it was only temporary. The fact that it lasted this long is surprising."

Riku: "…So what do you plan to do? I'm sure that there is something you have or want to do. I'm sure of that."

Kasai: "There is. I need Sora…to erase me…"

(1) Where they are, I don't know. I just made it up.
