Summary: By the Pandora's curse, he and Kaito got separated. When he got a chance to be with Kaito again, would Shinichi take it? Would they get together again or forever separated? KaiShin, girl!Shinichi~!

Author's rant: Well, this story is kinda for Miracle or Magic since this was inspired by her story, Marionette (which you really should read! It's beautiful!) and I got her permission to use the idea of Kaito being immortal but my story really has nothing to do with hers. The idea haunted me for days so I just wrote this to get rid of it. It was intent to be a one shot but the plot bunnies wouldn't agree, so I decided to divide it into two parts :3.

And because of my shitty English skill, there were some parts that I couldn't get right, so please forgive me for my bad grammar and awkward paragraphs *bows low*. Beware of OOC-ness too, I tried to keep them IC but I failed, yeah...

This got some cross-over with manga Yami no Matsuei but nothing too much, you don't have to read the manga to understand :D. And how the people in Yami no Matsuei work are my ideas cuz I don't really remember how they really work…so yeah.

Disclaim: I don't own DC or MK...There, I say it, happy now?

Edit: Just correcting some typos, nothing much v^^.

That's done~! Please enjoy~!

Immortality.

By: Shimizu Hikaru.

…Darkness.

"Where…am I?" a weak voice echoed.

"Welcome, Kudo Shinichi," a calm voice said back.

Shinichi slowly sat up. He looked around groggily but there was nothing but darkness. He turned his eyes back to the boy standing in front of him. The boy, looked around 16-17, had blond hair and pierced green eyes; he wore a simple jacket over an orange shirt and blue jean.

"Who are you? And where am I?" Shinichi asked again.

"My name is Kurosaki Hisoka, a Death God, nice to meet you," the boy, Hisoka, then looked around, "You are in the land between the Dead and the Living."

"Oh right, I'm dead," Shinichi muttered, not really surprised. After all, Pandora was real, so why not Death Gods?

He did live a pretty long life. He was dead and Kaito….

"So, you're here to lead me to The land of the Dead, right?"

Hisoka sighed, "Yes, I'm supposed to but…" he paused, his eyes twitched as if he remembered something he did not like.

"…My idiotic partner thought your love was such a tragic love," Shinichi raised an eyebrow at that, "So he begged Hades-sama a chance for you."

"A chance for me? What do you mean?" Shinichi asked bewilderedly.

"Yes, you will have two days to make your lover say he loves you, you then will get a chance to live, to be with him again," Hisoka explained.

"There will be some changes in exchange for your chance," he added.

Shinichi sat still for several minutes before looking at Hisoka oddly, "Why does your partner help me?"

Hisoka shook his head, "That you'll have to ask him yourself." He sighed then looked at Shinichi his eyes softened, "Well then…good luck."

Shinichi smiled back softly, "Thank you."

And then, everything went black.

When he woke up again, he was in his bed in his house-the Kudo manor.

"Urg…" he sad up and ran a hand through his hair. He realized that his hair was much longer than it should have been.

"I need a hair cut…" he mumbled to himself then froze. His voice, it was too high for a guy. He jumped out of his bed and ran toward the mirror hung on the wall.

In the mirror, reflecting a girl in her teen clad in his favorite pj. She was quite tall for a girl and had long dark brown hair and HIS usual cowlick. In general, she looked quite pretty.

"…Is that me?" Shinichi stared at the mirror as if expected the reflection said 'no, it's not' but blue eyes just stared back at him mockingly. He turned around and dragged his feet back to the bed.

"Is this the change that Death God talked about?" he sighed.

xxxxxXxxxxxXxxxxx

Shinichi walked out of her (yup, he had grudgingly accepted his new gender) house. The inside looked just like she remembered but the outside looked much older and creepier than it was in her memory. Asaga-hakase's house was no longer there, instead it was some stranger. As she walked down the street, she noticed everything had changed so much, it was more advanced and modern. Well, she did spend three years copped up in her house because of her old age and illness.

She smiled to herself, it felt weird to be in a girl's form, a young one at that. Then her smile turned sadly…Kaito…She remembered his ever youthful face and his stupid cheerful smiles. He had never aged, never changed. He had been always by Shinichi's side as Shinichi had got older and older as the time went by.

…Kaito…

'I have to find him…only 2 days.' But it was hard to find Kaito if he didn't wish to be found.

"Did you hear? KID-sama's gonna strike again~! Wah~!" a young girl's voice snapped Shinichi out of her thoughts.

"Of course~! I wanna see him again! Ah~, I wish he'd appear right here and sweep me up in his arms! Uwah~! I'd die happy!" the other girl beamed and then the two of them burst out giggling.

"Excuse me?" Shinichi ran up to them.

They stopped walking and turned to her questioningly, "Yes?"

"By 'KID-sama', did you mean Kaitou KID?" Shinichi asked.

The girls beamed. "Yup! His heist is tomorrow night~! Ah, I can't wait to see him!" one girl chirped happily.

"Here!" the other thrust a newspaper into her hands, "It's on the news! And you can have that." She gestured toward the newspaper cheerfully.

"Ah, thank you." Shinichi bowed.

"You're welcome~!" they both said and then walked away, giggling.

Shinichi quickly turned to the newspaper. There, on the headline was 'The Immortal Kaitou Strikes again' on top of a picture of KID in his costumer, stood under the moonlight.

' KID has sent his note yesterday and the police has found out the time and the target. The target is the Starlight Tear, that will be introduced tomorrow night at the Beika Museum. The time is 9:30 pm.' The news read.

Shinichi smiled fondly at the picture but then her eyes caught the date and she froze.

'8/9/2043'

'2043?' Shinichi thought frantically, 'but the last time I checked it was only 1993!'

She looked blankly at the news, 'So…over 50 years have passed…' She turned around and began to walk home. She then understand the change, the advances…

But had Kaito changed? What had he been doing those years? Shinichi looked up to the sky

'Has he found anyone to replace me?'

xxxxxXxxxxxXxxxxx

Shinichi spent her time losing in her thoughts. She vaguely remembered eating some hamburgers and going to the toilet and then she found the following night had come. Only around 2 hours left and the heist would start.

Shinichi let herself sink further into the comfy sofa in the library while letting her eyes wander.

Everything in the house was clean, no dust and the water and electricity still running. Someone must have been cleaning and paying the bills but it seemed as if no one had been staying there.

The only one she could think of doing those things was Kaito. It made her heart ache with both happiness and sadness. Happy that Kaito still remembered Shinichi, still loved Shinichi and sad that Shinichi couldn't be with him all those years… he must be lonely.

She looked at the clock hung on the wall and stood up. Time to go, the heist would start soon and she would see Kaito again soon…

xxxxxXxxxxXxxxxx

"KID-SAMA! WE LOVE YOU~!"

The fans screamed their lungs off, Shinichi covered her ears and rolled her eyes in fond annoyance.

She then sneak her way into the museum, passed the guardians safely. There was someone screaming about capturing KID and he really reminded her of Nakamori-keibu. She pressed herself into a dark corner and held her breath. There, she wouldn't be discovered yet still can watch what was going on.

At exact 9:30, KID appeared in a puff of pink smoke, in front of the case holding the diamond.

"Good evening my dear~," KID grinned and bowed down as a showman.

Shinichi felt her heart speeding up at the familiar figure and voice. She didn't know that she missed him that much.

"GET HIM!" the inspector roared angrily and the entire taskforce jumped at KID, who disappeared with an insane grin.

Shinichi looked at the pile of police on the ground struggling to get out of the glue KID had set up. "I thought they would have learn…" she rolled her eyes.

KID then reappeared on top of the case holding the diamond in his hand. He grinned down the taskforce, "Ah, I didn't know you were that eager to see me~."

"But I have to go now…what a pity," he said in a mock sad voice, ignored the inspector's angry growl, "Bye bye~!"

And then he was gone.

Shinichi ran past the pile of police, pretending not to hear the inspector's yells after her, to the staircase. When she got to the top, she was out breath.

She panted quickly then looked up to see KID holding the diamond to the full moon.

"Why are you still doing that?" she asked, startled the thief.

KID turned around to look at her, Poker Face in place. "Good evening, oujo-ssan," he greeted, "and what do you mean?"

Shinichi stepped toward then stopped, "I mean you've already found the Pandora, so why do you still steal-"

If KID was surprised, he didn't show it, "Borrow, oujo-san, I am only borrowing them…and how do you know about the Pandora?"

She raised an eyebrow at him, "I'm a detective."

KID's expression darken, "I see…he waa a detective too…"

"Kudo Shinichi?" KID's Poker Face shattered as he stared at her surprisingly.

"How-" he began but was cut off as they heard the taskforce ran up the stair…it seemed they successful escaped KID's glue.

"Go, I'll see you again at the Kudo manor, Kuroba Kaito," she smirked at his bewildered face.

But he quickly got his Poker Face under control again, "Very well, oujo-san. I'll be waiting." He activated his hand glider and flew away as the taskforce burst through the door to the rooftop.

xxxxxXxxxxxXxxxxx

"Gosh, he's much annoying than Nakamori-keibu," Shinichi growled darkly as she walked hurriedly to the Kudo manor. They had kept her at the police station for and entire hour just to lecture her how she should not sneaking in and make her promise not to do that again.

'I have to hurry,' she looked at her watched and sped up her walking.

When she got to the Kudo manor, Kaito was standing there in his civilian clothes, tapping his foot impatiently. She walked up to him, " Good evening."

He nodded at her than his expression turned serious, "How-" Shinichi cut him off, "Not here, please." In a puff of smoke, Shinichi found herself on the manor's rooftop.

"Now, answer me," Kaito demanded beside her.

"I'm just curious about KID so I did some research."

Kaito narrowed his eyes, not believing her. She sighed, "Okay, okay…"

Then she turned to look at him seriously, "What if I told you that I'm Kudo Shinichi?"

"What do you mean? Don't mess with me! Shinichi is dead! 50 years ago!" Kaito hissed out angrily, making Shinichi flinch. "I don't know how you know about me and the Pandora, frankily, I don't care! You can say or do whatever you want! Just don't say thing like that!"

Shinichi's eyes widened at Kaito's remark. Then Kaito's shoulders slumped, "He's my most precious person…please don't…just don't…" he trailed off hoarsely.

For a moment, they sat still on the rooftop.

"I'm sorry," Shinichi broke the silence, "Uhm…you can call me Shiera."

Shinichi didn't know what she was doing, really. She was supposed to convince Kaito that she was indeed Shinichi and then Kaito'd say he love her, then she'd get to be with him again. But as she looked at his broken expression, she couldn't help but lie to him.

xxxxxXxxxxxXxxxxx

Kaito was angry with himself. Why did he drop his Poker Face in front of a total stranger? There was no way that she was his beloved Shin-chan! But why would she say something like that? That was just plainly cruel if she knew about him being KID , the Pandora and Shinichi then she must know about his and Shinichi's relationship and how precious Shinichi to him…

Kaito looked away and whispered, "I'm sorry, I didn't mean to yell at you."

"It's okay, I understand…sorry again…" was the soft reply.

"He means a lot to you, right?" she asked after a moment.

"Yes…" Kaito looked up at the night sky. Everything had changed so much but the sky hadn't. It still looked like it did that night, when his precious Shin-chan died. Kaito turned to Shiera, "I loved him, still do…"

The girl looked both strange and familiar, she looked a lot like Shin-chan, especially those blue eyes, "…but I guess I've kinda moved on…" he didn't notice her stiffened, " I mean it's been over 50 years and Shin-chan would want me to live on, live for him and to see the future for him…" he trailed off.

Shiera just smiled, a bit sadly, " That's good to hear…he must have want that."

For a long moment they both let the silence surround them.

"Aren't you lonely?" Shiera asked hesitantly.

"Mh, yea…but I'm used to it," he grinned. And again they both sat quietly.

Shiera looked at her watch then stood up silently. Without looking at him, she moved to get down.

"Where are you going?" Kaito asked.

"Ah, I must go meet someone." He blinked at her, "At this holy hour? It's nearly 12."

"Mh…just some business." And in another puff of smoke, Shiera found herself on the ground. She rolled her eyes but said nothing. She began to walk away without looking back, "Goodbye, it was nice talking to you."

Looking at her distanting figure, Kaito felt something in his heart ached then disappeared…just like it did 50 years ago…

Without thinking, he followed the girl.
