I don't own Date a Live or Kingdom Hearts, all are owned by their respective owners.

"It's back. It's really back. My world." Shido began to cry, relived that all he Sora, Goofy, Donald, we did it. H continued to sob quietly as he stared at his home city Tengu City.

(Keyblade)

"You! You're here to kill me too!" The armored girl yelled and rushed towards.

"Hey, hey wait!" Shido saw that she wasn't stopping. By instinct he summoned his Keyblade and blocked her sword.

The Keyblade appearance, like all the Keyblades, had the semblance of a giant key the colors it had was mostly of pure silver and white. The body was composed of two sharp blades and the guard was shaped like a heart that appeared to be made by flowing cloth with an angelic carved face that connected the base to the guard. The edges of the blade appeared to be glowing. The colors kept changing from purple to green to yellow and so on. Lastly the key chain attached looked like a small purple teddy bear.

(Keyblade)

"Guh… where I'm I?" Shido muttered as his vision slowly came back to normal from the blinding light that suddenly enveloped him.

"Ah, so your awake."

His vision finally focused and saw the one tending to him.

His eyes widened and mouth went a gaped.

"It looks like you regained conciseness. That's good. I'm the analysist officer of Fraxinus, Reine Murasame"

He didn't hear what she said as he took in her appearance.

The silver hair and the color of her eyes. The small purple teddy bear on her breast pocket. What made Shido even sure who this was what he felt in his heart. It was tugging itself to Reine.

The now named Reine was confused at Shido's behavior.

Shido slowly stood up and walked towards her. His hand slowly went to her cheek and tears began fall.

This worried Reine and was about to speak. But she stops as one word that Shido muttered that shocked her to her core.

"Mio?"

"Heh."

"It's you, isn't it? Mio."

Her body tremble as the chart she was holding fell to the floor. Tears began to fall as well as unimaginable happiness swelled in her heart.

Shido hugged her tight. After so many years they were together again.

"I finally found you Mio."

Her arms slowly rapped around him as she muttered his name after so many years.

"Shin."

(Keyblade)

The two long lost lovers sat quietly. Mio, her true form sat with Shido in his room. She was leaning on him as Shido's wrapped his arms on her.

After their reunion. The two decided to act that they didn't know each other for now from Kotori and the crew.

Taking in all the information about the spirit princess and what he is supposed to do. Mio left her other half Reine with Fraxinus to handle some last minute details for Shido's future engagement with princess.

Now the two just wanted to drink in each other's presence. As the two had their fill, Mio began her questions for her long-lost love.

"Shin, how did you regain your memories?" She asked the big question on her mind. In all honesty, Mio didn't care in the slightest how. It was just way to hear his voice.

Shido rubbed the back of his head. Unsure how to tell his adventure to Mio.

He knew that it was against the world order to tell anyone about the bigger universe they are inhabiting. Donald made sure that he and Sora drilled it in their brains.

So, he decided to keep most of the information and tell her just one thing and hope Mio would understand. He got the feeling she would any way.

"I can't really tell much Mio. It concerns something big. Bigger than you could imagine." He stretched his arm and in a flash of light summoned his Keyblade. "All I can reveal to you is this. This is called a Keyblade. A weapon that is said to be the mightiest in all existence."

He explained and Mio began to touch the strangely shaped weapon. She didn't know why, but when she touched it, she felt it was like she was feeling Shido's very being. It was warm and comforting for her.

"How did you get this Keyblade?"

Shido looked at her. She saw the troubled look on his face. "You can't tell me that?"

"Yah… Not even that Mio."

She was crestfallen, but she won't hate him for it. After all she had kept her plan from even as well.

"Then…" The spirit of origin said as her gaze went to her love. "I'll wait for the time you will tell me."

Shido stared for a while, but he put on a great full smile.

"I promise. I'll tell you everything someday."

She nodded. "Then in exchange." She clasped her hands gently on Shido's cheeks and slowly inched ever closer to him.

"Mi-Mio?

"I wont hold back anymore Shin. I waited for so long. So please Shin…"

Their lips met and Shido was completely lost himself with her presence. The soft lips, the heat from her body he felt as she laid over him. He didn't fight it. He just accepts her and the two continued all night.

He made her wait for far too long.

(Keyblade)

Shido sighed in exhaustion. It was only been a few hours since he saved Yoshino and sealed her angel.

Mio or her double, Rinne said she will look after Yoshino for a while and that he should rest up. He fell right into bed forgetting to even change his clothes. He didn't even wait for Mio to return and sleep together.

As he tried to drift to sleep. He noticed a box that he didn't remember having on the side of his bed.

Wondering what it was he stood up and went to open it.

What he found inside was a dark coat with a large silver zipper running through its center. He studied the strange clothing until a piece of paper fell from it. He picked it up and read its contents.

"Hey Shido! I'm giving you something that will be useful to you in the long run. Hope you like it! Don't worry its free!

~M.O.M."

"Huh?" Shido said, baffled at the letter. Who ever wrote it seemed to be acquainted to him? But he can't remember anyone who was named M.O.M.

Still, it wouldn't hurt to try it on. His inner Chūnibyō said it looked cool anyway.

(Keyblade)

Isaac Wescott stared at the dozens of screens showing the chaotic battle happening outside of the building. His usual confident smirk wasn't present, but an annoyed and troubled expression.

As he watched his army of WIZARDS are being overwhelmed by the forces of Ratatoskr. All of the spirits that they have saved and the WIZARDS of the London branch that joined them months ago and the traitor Mana Takamiya were fighting his army.

Hermit, Nightmare, the Berserker Twins, the spirit that was rescued Sister, Angel and the unknown spirit that appeared not to long ago Ruler. The Special Sorcery Service along with their Ace Artemisia Bell Ashcroft. Where making quick work of the army.

But he still had confidence that Ellen, Minerva and Jessica would handle or the very least delay them from getting near.

"BOOM"

He heard another explosion from below. It's only a matter of time before the hero would arrive and save the princess.

He put his attention to the monitor that showed the floor where the explosion happened. He saw him. The boy that gave him so much trouble. Shido Itsuka. He sported the black coat he always wore when in combat, but now he didn't have his hood over and clearly showed his face.

As of now he was arguing with the spirit Diva, Miku Izayoi. Along with a small girl with extremely similar feature with the spirit Ruler, who was holding his hand.

He wondered who the small child was. "Is she a spirit? There was no data on this child." He smiled. "Well, I can ask the hero when he arrives to save the princess.

His eyes the wen to the unconscious Tohka. His excitement grew as his pane is drawing closer and closer. Once they fatally wound Shido. Tohka will feel utter despair and will finally Inverse.

"Then finally our dream will come true."

BOOM!

He felt a gust of wind and he heard the crumbling rubble that was once the door. He turned to greet his guest.

As expect he saw Miku, Shido and the little girl. The child was happily pointing towards the unconscious form of Tohka.

"Papa, Tohka is right there!" She said pointing at her.

"Yup, good work finding her Rio." He responded as he ruffled the girl's head. In response Rio giggled happily being praised by her father.

"Geez, to bring your own cute daughter to somewhere dangerous are you insane! That's just wrong! That's why men are so!"

"Yah, yah I get it." Shido said, dismissing Miku's comment and the girl gave him an annoyed glare.

"So, the child is Shido Itsuka's child." So many questions raised, but a matter for another time. He must greet his guest after all.

"Welcome my guest. I presume that you are friends of Princess?" He said in a polite, yet at the same time condescending manner.

They turned to him and didn't expect the reaction he was getting from the black coated hero.

His faced showed unbridled furry. It was if his stare would kill him on the spot.

"When I met Ellen Mathers, I hoped you weren't alive, But I guess I was asking for much. I really did hope when the worlds where restored, your rotten heart didn't come back."

Everyone was confused at his words. Not knowing what it meant.

"Well, I guess it also okay. Once I save Tohka I can beat the living crap out of you." He said as he pointed the Deus Keyblade at Isaac.

"I'm sorry have we met before?"

Shido gave a smirk as his eyes locked on with Isaac's. "What? Have you forgotten about me? Remember thirty years ago, you killed me and my sister and nearly kidnapped Mio!"

Isaac eyes widened for a second. But a smile formed as he finally remembered what he was talking about.

"Ah, its nice to see you again, Shinji Takamiya."

(Keyblade)

"So, how's the coat I gave you doing for you?" The man with the same black coat Shido has asked as the strange man drank the coffee Shido gave him. "And this coffee is great! where'd you get this?"

Shido wasn't sure how to respond to the man. About an hour when the girls went out to do the grocery for him since he was still recovering from the whole Origami incident, he answered a knock on the door and saw the man standing there.

He thought he was part of the Organization, but he felt no ill or hostile intention from him. In fact, he greeted Shido like he was an old buddy of his.

He was confused of course since he well remembers if he ever met this guy.

Shido welcomed him inside and the man nonchalantly came in and now was sitting with him.

"It's been a big help. Especially with my espionage mission from DIZ and with the Corridor of Darkness."

"Hmm good, good." The hooded man said with a cheery tone. As he sipped the coffee on his hand.

"And those girls of yours? Treating them, right?"

He raised an eyebrow from his question, but saw nothing wrong to answer him.

"Yah. There doing fine. I know they are." He said as he placed a hand over his heart.

"Still, beachful though. To those girls your everything to them. You're their emotional crutch. That thing called Inversion is the least of your worries. In that moment of despair. The darkness will not hesitate to consume their hearts. Remember that well Shido."

He heard the seriousness of his word's and he nodded wordlessly. His face showing the understanding of the warning.

He could tell that the coated man was smiling in relief. "Then I guess that's it for now."

"Huh?"

"Just wanted to see you in person really. Also, this coffee of yours is perfect!"

He got up as he drank the last drops of coffee. Suddenly the front door busted open and Shido's harem entered the room.

"Shido where back!" Tohka shouted excitedly as she entered the living room.

"Papa! Rio, I missed you!" Rio, rushed in and hugged her father. Ignoring the coated man in the room.

"I missed you too Rio-chan." He said as he returned the hug.

"Umm, Shido-san who's this?" The Spirit of Ice, Yoshino ask gaining the attention of everyone who arrived. In the back, Reine suddenly began to feel uneasy looking at the figure in the black coat.

"This is the guy who sent me the black coat. He's uhm, the Master of Masters I guess."

"Sup girls!"

He said while giving a two-finger salute.

The girls didn't know what to say at the mysterious figure they just gave him a creeped outlook.

The Master of Masters slouched in depression from their rection. "Geez, your harem is pretty cooled Shido."

Shido spat out the coffee he was currently drinking and began to fluster. "Th-Th-They aren't my harem! Nope definitely not!" He denied, still not accepting the reality he was now living with.

"Says the guy who already has a daughter with one of them."

Shido had nothing to say to his claims.

"You have my sympathy girls."

All of them sighed in exasperation and silently thanked the Master of Masters.

"Well, I should leave now. Don't want to be the third wheel in your love nest."

"It's not a love nest!"

He began to walk out to the door. He stopped and his gaze turned to Reine. They stared at each other, but Reine was sure he was smirking at her.

"Really a miraculous thing you are thing you are."

Reine wasn't sure what to make with his words.

The Master of Masters opened the door and went outside. But stopped before completely getting out.

"Oh, one more thing." He turned to them and spoke. "May your heart be your guiding key." With that he finally left.

"What was that all about." Natsumi asked everyone.

"Pa-papa!?"

They heard the frightened and worried voice of Rio. As they turned to the father and daughter. They too were left in shock.

Shido had a horrified look. He was breathing heavily, hyper ventilating at this point. His hands slowly clutched his head.

Then he screamed in horror as he fell to the ground.

"Shido!" Evey one screamed and went to their saviors side.

(Keyblade)

"That was pretty reckless of you. Luring the Heartless like that." Riku said as his stare made Shido lookdown in shame. Even if it was blindfolded.

"I… had no choice." Shido began. He didn't know how to explain his action. And the stares of his girls didn't help at all.

The girls wanted to say something to Riku. To defend Shido in anyway. But the tension in the room stopped them from saying anything.

They were completely in the dark. They knew Shido was hiding something big. The fact he had powers that didn't have any connection to the sealed spirit power really gave it away.

And that strange key shaped weapon. Lert's not forget about that.

"One of the organization members attacked us and was about to kidnap Mio. They brought an army of Nobodies. So, I…"

"Use the power of darkness and called the Heartless." Riku finished, not accepting his excuse.

Shido nodded silently.

Riku sighed. Feeling a headache coming. "Let's not discuss this now. We need to go. DIZ found Roxas's location. We move in an hour."

"What?! Shido your leaving?!" Tohka blurted out as she stood up. Her eyes were pleading at him to explain thing already. She was tired on being in the dark.

Shido and Riku stared at the girl. This caused the girl to flinch, but recomposed herself.

Riku sighed once more and went back to Shido. "You have an hour Shido and we need to move."

Shido gave a node as he took Riku's hint. "Right."

Riku opened the Corridor of Darkness and left the scene.

Shido fell on the sofa and gave a heavy sigh. He then looked at everyone present in the room. His heart crumbled a bit at their gaze. The guilt was eating him up.

"Shin…"

His eyes turned to her. To Mio Takamiya. To him, she was his entire being. The girl that he loves. Even above his own heart. That's why his Keyblade. Its true form was a mirror to her. That's why it is called the Deus Keyblade.

He smiled inwardly. If he was Sora, then she was his Kairi. He coudnt help but compare it with his friend.

"I…we have been patient. WE gave you the time you need to tell use everything."

As she talked her face showed such a pleading look that it just made Shido feel even worst.

"But now we need answers Shin. Please…" Shido saw that tears were beginning to fall from her eyes. "Please tell us the truth."

He sighed once again and stood up. He put his hood on and slowly walked towards the window and stared at the moon. He didn't know why, but it felt so nostalgic for him.

"Nia." He called the manga writer spirit. Causing her to flinch in surprise. "When Kurumi went to you to ask about Mio. What did Rasiel say."

"W-well." She began, trying to regain her composure after she was suddenly put on the spot light. "To tell you the truth. Nothing."

"What?! Isn't Rasiel the all-knowing angel?!" Kotori yelled out in shock.

"No joke imouto-chan. When Kurumin came to me to ask about Miocchi. The strangest thing happened to Rasiel."

"What do you mean Nia-san?" Mayuri spoke what everyone wanted to ask.

"When I used Rasiel to find a way to beat Miocchi, it-."

"The angel started to jitter and glitches started to manifest around it. Then it abruptly stopped and smoke came out of it." Kurumi interjected, giving her part with the conversation.

"Only one word appeared. It was your Keyblade."

"Hmm…" Shido muttered. "I guessed as much."

"What do you mean Shido?" The spirit Ruler, Rinne Sonogami asked the black coated boy.

Shido flicked his hand and the book Rasiel appeared in his hand. "Rasiel is the book that knows everything about the World. Yet that is its only limitation. Only THIS World."

"Question. What do you mean by this world Shido?" One of the Berserker twins. Yuzuru asked. Confused what Shido was emphasizing.

"Like I said, THIS World. OUR World." He dismissed Rasiel and then summoning his Keyblade, raised it and pointed it to the moon. "The Keyblade is both part of Our World and not at the same time."

"Not… of our world?" Origami muttered in wonder.

"Could you just get on with it! The suspense is killing me!" one of the members of the SSS, Ashley blurted out in irritation and was met by a hand of Lenora hitting her square at the middle of her head.

Shido chuckled softly. "Where to start though?"

"Oh, I don't know. How about what you mean about the World! Or how exactly you were able to heal both Artemisia-san and Mana with that Elixir thing you called! Or maybe where you took Rinne and Mayuri and was able stabilize them to remain here! Also, on how you were able to save the Quasi-Spirits and brought back Sawa-san" Kotori listed all the impossible thing that Shido had able to achieve. "And what those Heartless things and the people who wears the same coat you have that attack us!"

"Hhaaa…" Shido sighed seeing that he would be telling from the very beginning. "Well, I guess the beginning would be best."

He turned to them and all of them tensed as they saw how serious his face was.

It was time to tell them.

"Then I will tell you all what I have been keeping. On how our world and all its people, including you all were devoured by darkness. On how I ended up surviving the worlds destruction and ended up in another world called Travers Town.

On how I met with my friends, Sora, Donald and Goofy. On how we traveled the worlds to restore everything back to normal, and…" He turned back to the moon and raised both his hands towards it and made a shape that resembled a heart. He didn't know why, but he had the urge to do it. "I will tell you about, the heart of all worlds, Kingdom Hearts."

(Kingdom Hearts)

Hey guys this is a little something I wanted to make. As with the new season of Date A Live and me finally had time to play KH3 and with the hype of KH4 I got the urge to make this small experiment.

Don't know when I will further this story, but if some people will like this. I might find the time to make this soon.

No promises though.

Well R&R and see you all then.
