Once Upon a Little Time

Summary: Due to a bit of Shinra's experimentation, Izaya somehow finds himself in the past. And not just anywhere in the past, but in Shizuo's childhood home. Thinking this is the perfect opportunity to study his favorite toy, Izaya ends up staying with kid Shizuo. But soon Izaya sees a side of Shizuo he's never bothered to look at before, and he can't help but see his future enemy in a different light.

Rating: K+ for mild cursing

Pairings:Shizuo/Izaya

This is a deanon from the kink meme. :) I had so much fun writing this cute story! I've got most of it written up, but I'm working on expanding parts of it so hopefully updates won't be that terribly slow, especially with the wonderful help of my beta Sunny! She betaed this chapter so a huge thanks to her~

Here's the prompt I filled in case anyone wants to see:

Izaya X Kid Shizuo

I've never actually seen this, and I've been wanting to for awhile. It can be however you want, as long as it's Izaya and little kid Shizuo.

Bonus if:

-Izaya is only with little kid Shizuo because Shinra (or his dad) somehow sent Izaya into the past.

-Kid Shizuo hides Izaya in his room since Izaya can't exactly go 'home'.

-Izaya originally agrees to let Shizuo hide him because he finds that it'd be the best way to observe him, but finds himself falling for Shizuo. (The part of the past can be a bit before his strength appears, making Izaya like the kind Shizuo, or after it appears, when he's hurt a lot, making Izaya fret about how fragile Shizuo seemed to be.)

-Kasuka finds out about Izaya, doesn't tell anyone, but gets jealous.

-Izaya eventually tells Shizuo he's from the future, and says that he might have to go back.

-After hearing the above, Shizuo states that he'll wait forever for Izaya if he does go back.

-The person who fills this can decide if Izaya ever does go back or not, but if he does, Shizaya, and lots of it.

Izaya was going to kill Shinra later for this. And he wouldn't be swift about it either. No, he'd make sure the underground doctor suffered.

Izaya groaned as he rolled over, blinking away the bleariness in his eyes as he tried to focus on his surroundings. He hissed as he moved his arm and felt pain sear through it. He cursed as he realized he must have hurt it during his fall. Damn Shinra. What the hell had been that thing anyway that the underground doctor had pushed him through? Izaya had thought it was weird when he arrived at Shinra's home at the doctor's request and found a weird machine that looked like it belonged in a sci-fi movie. And he hadn't expected the bastard to actually push him through it—or that the impact would hurt this much.

A shuffling noise and a surprised squeak made Izaya perk up as he blinked away the dizziness. Finally focusing on his surroundings, Izaya realized that he was no longer in Shinra's home.

Some poor kid, probably no older than seven years, with messy brown hair and wide, mocha eyes was staring at him with a shocked expression. Izaya cursed under his breath again. He was definitely going to kill Shinra later for getting him in this mess.

The kid opened his mouth and Izaya panicked for a moment, thinking the kid was going to scream for help. It's not that Izaya didn't have the skills to escape easily, but he really didn't want to deal with freaked out parents or looking like a criminal. Just as Izaya was about to move before the kid could say anything, a feminine voice rang out in the air, "Kids! Dinner's ready!"

'Damn. I'm in trouble,' Izaya thought.

He froze as the kid's eyes flickered to the doorway, but then the kid did something Izaya didn't expect. "I'm coming, mom!" he called out. The kid then turned back to Izaya, studying the raven for a moment before he pointed towards the bed, "You can rest there. I'll make sure to bring something back for you."

The kid rushed out the room, leaving Izaya alone and blinking with surprise as he tried to comprehend to what just happened. Did that kid really just tell him to relax? How…unexpected. Izaya's interest was piqued as he thought about this kid's reaction to him. Normally, wouldn't someone scream at the sight of a stranger in their room? Why had this kid hid Izaya from his parents? Why didn't he seem freaked out by Izaya's sudden appearance? Izaya suddenly became excited as he thought about this kid's unpredictable acts. What an interesting person he had stumbled across~!

Instead of escaping like he had been intending to in the beginning, Izaya decided to stay and study this kid more. Maybe he would be a great apprentice to take on since Saki had failed him. As the sounds of a family eating came from downstairs, Izaya took the liberty to explore the kid's room.

It was like any typical kid's room; it was messy with cartoon posters hung on the wall. There was a bookshelf mostly filled with manga and action figures, and a desk where unfinished homework sat along with scattered school supplies. Izaya furrowed his brow in confusion as he saw the kid had written the wrong date on his homework but shrugged it off as he continued studying the room. The bed was unmade and clothes were strewn about the floor. Izaya sucked his teeth with slight disapproval and then caught sight of a picture frame sitting on a nightstand next to the bed. The raven picked it up with a curious expression and almost dropped it in the next moment.

There were two kids in the photo, the brunette boy from earlier smiling widely with a peace sign as the other kid stared at the camera with a bland expression. It wouldn't seem odd to anyone else, except for the fact that Izaya recognized the other kid.

'That emotionless expression can be recognizable anywhere.'

That was Hanejima Yuhei in the picture. But Izaya knew that wasn't his real name. After all, an informant of his caliber would know that Hanejima Yuhei was just his stage name and that his real name was Heiwajima Kasuka. And of course Izaya knew that Kasuka was that monster's little brother. But then didn't that mean that the other boy in the photo, the one that hadn't acted the way Izaya had expected…?

Izaya's train of thought was interrupted as he turned at the sound of the door opening, the boy reappearing as Izaya heard the boy's mother call after him, "You better not spill any of that food in your room, or so help me I will ground you for a week, Shizuo!"

"Yeah, mom," the boy answered with a roll of his eyes, closing the door behind him and turning to Izaya.

And suddenly Izaya connected the dots. Those mocha eyes, the abnormal reaction, Kasuka in the picture frame, the name the woman had said, and the wrong date on the homework. Izaya couldn't believe it. That hadn't been just any machine Shinra had pushed him through. But was it really possible that the machine had transported him to the past? And to Shizuo's childhood home no less?

"Here, are you hungry?" The kid asked, interrupting Izaya's thoughts as he held out the food in offering.

"Yeah," Izaya said slowly, his scarlet eyes studying the boy carefully as he took the offered plate. "Thanks…?"

Sensing why Izaya had trailed off, the kid filled in the blank for him, "Heiwajima Shizuo. That's my name."

Izaya felt his eyes widen, and his lips curled into a devious smile. Now this was a much more pleasant surprise than he thought. "Nice to meet you, Shizu-chan. My name's Orihara Izaya."

Ah, by the way, technically Shizuo is supposed to have a broken arm during this time period I'm writing the story in, but the broken arm really doesn't work with what I've written so ignore that fact please. XD

These chapters will be pretty short considering there was a character limit on the kink meme for those who are used to my longer chapters. But updates should be relatively quick~ :)

I hope you guys enjoyed the beginning! Review please? It'll make me one happy writer. ^w^
