A/N: Yup, it's another story from me, even though I've got others still being worked on. The idea demanded working on before I forgot about it.
In this story, Sora is the resident of Twilight Town, Xion and Kairi are twin sisters, Roxas... well, I won't spoil that bit, and Twilight Town has lost it's perpetual sunset in favour of a normal, proper cycle of day and night. Though that last has nothing to do with anything except that I decided there was going to be proper nights there now.

As usual, I don't own Kingdom Hearts.

Right, that's all from me. Get reading, enjoy, and if you like it, review!

It had begun with them – the twinned girls. You could tell them apart only by their hair, one had hers dark brown, the other's was a raven black. They were identical otherwise, but only until you knew them.
Sora knew them both. He'd been the one they turned to for a tour of the town two days ago – an unexpected request, but not one he was about to turn down.
They were Kairi and Xion, moving to Twilight Town from some distant place for the summer vacation, and the new school season coming right after it.
Sora had noticed slight differences in the girls as he gave them the tour. Kairi was more outspoken but calmer, while the quieter Xion flitted between different emotions almost constantly and was harder to surprise.
He'd walked them to their new homes and helped them unpack, then as night began to fall he too headed to his home, overlooking The Usual Spot – a place where some of the other kids in town hung out from time to time. He and Riku had their own place, down in the underground tunnels where almost no one ever went.
Two days ago. That was when it had begun, because no one had seen them since then.
On the night of that day he'd met them, he'd found he'd started to grow attached to Kairi – but he was torn, Xion had her attractions too.
He'd not slept well that night, seeming to dream about someone like him, but not him, someone who'd take one of the girls away from him and leave him with the other. The dream-stranger seemed to know everything he did, and be able to do anything he did.
When he woke up the next morning, the torn feeling was still there, but subtly different, as if there was another person within him. It was an absurd idea, so it had been shoved aside and ignored, and Sora had gone about his life as usual.
That was yesterday. That was when Riku had mentioned he'd seen Sora giving the twins their tour, and remarked that if no one else did, he'd ask after one of them. Like Sora, Riku also leaned toward Kairi over Xion.
They'd teased each other over it a bit, but it was good-natured teasing that always existed between close friends.
Then there was today, when they'd found out the news. Sora lay back on his bed, staring at the ceiling as if it would give him the answers.
No one had seen them even once since that first day. Their home was neat, tidy, and devoid of life. Neither of them were there, nor was there any trace of them leaving. There was a house key for each of them, but both were still inside. The only spare key belonged to the landlord, the one who'd let Seifer in to try and find out what had happened.
He hadn't found anything, and now Sora was beginning to worry. People didn't just disappear without a trace. Something had happened, but what?
It troubled him as he lay there until finally Sora fell asleep...

...and Roxas woke up. He looked out through Sora's eyes for a few moments, then felt them become his own.
Two days ago. He was still just a part of Sora then. But part of Sora had wanted Kairi, and the other part, him, he wanted Xion. The night after they'd met them, Sora had dreamed about him, and the longer he dreamed about him the more complete he became. By morning, Roxas was there, watching, seeing, hearing everything that Sora did from inside Sora's own mind.
And then last night. When Sora had gone to sleep, he'd subtly nudged Sora's mind aside, taking care not to wake him and for the first time, experienced everything for himself. Sora's body had changed just slightly when he took control. The hair changed style and took on a slightly different colour, and his features were slightly different. Sora's blue eyes still looked back from that face though, the only telling-point that Sora was still there, dozing away unknowingly.
Unlike Sora, Roxas felt there wasn't any point in burdening himself with petty things like morals or ethics. He also felt he needed his own identity, so had spent the night taking whatever he wanted to create that identity, then carefully prying up a floorboard in Sora's room to hide it in so Sora would never know anything about him – not to mention anyone else. Roxas had the kind of freedom that Sora never would have had. He didn't have to do anything he didn't want to, he could do whatever he wanted, and he took whatever he wanted. He thought of himself as a creature of the night, because that was the only time Sora slept. All Sora needed to do was fall asleep, and he could take over again. He didn't have to give up that control by morning, he could keep it as long as he wanted, but Sora's mind would start to try to wake up not long after sunrise, and it was hard to keep it from actually waking up and realising what was going on. He'd decided to take care not to let that happen, getting back to Sora's room and stashing his own belongings long before Sora woke up.
Tonight, now tonight was different. Sora had heard about the disappearance of Xion – oh, and Kairi too – and so naturally, Roxas had too. Sora, in his good-natured way, wouldn't get involved in looking for either of them. Not yet, anyway – no, he'd wait until he knew there was something wrong to start getting involved, unless someone asked him sooner, but he and Seifer didn't get along well, so it was unlikely.
Roxas didn't care for that. He swung himself off Sora's bed, picked out the clothes he'd got himself the night before from the stash and dressed himself. A black jacket without sleeves, with a white one over it that did. Grey pants – mostly grey, anyway – and grey trainers with red straps, instead of the normal laces. Normal was something that happened to other people, he'd already decided. This was his look – no one elses, certainly not Sora's with his ridiculous getup. There was no way he was going to be seen wearing that again, it even made him feel ridiculous just wearing it the night before. He hadn't had any choice then; either wear what Sora had, or go around without anything on... well, he'd entertained the thought briefly, but decided it was probably better if he put up with it while he got his own stuff.
With a last glance down to the stash, he wondered whether to take one of the five rings he'd stolen the night before, each one with a different design on them. They were where he'd taken his name from. They'd been lined up beside each other in a display, spelling out what would become his name. So similar to Sora's name, just like he was still similar to Sora, but different enough to be distinctive. He didn't even know why he'd taken them after they'd given him his name, they'd just caught his eye... and the next thing he knew, they were pocketed and he was walking away without a care for what he'd just done.
Why would he care? He had the perfect cover. All he had to do was hide his stuff and let Sora take over come morning. Even if anyone found out about the link between him and Sora, he didn't have to take control. He could sit back and wait for the suspicions to fade, then he'd just carry on where he left off. Let Sora take the blame for things. What did it matter to him?
Roxas decided not to take one of the rings tonight, checked his reflection in a mirror, then opened the window and dropped down to the alley below that lead to The Usual Spot as Sora knew it. He listened nearby and heard nothing coming from it, so glanced inside. Old furniture, knocked up tables and even an oil drum. Who'd want to meet up here? It was full of junk.
The night-time streets were quiet, barely anyone around. No one paid much attention to him, he was just another new kid who'd arrived recently. Or whatever else they thought.
Sora's memory of Xion's house was clear enough that even a blind mouse could have followed it. It was just opposite the place the trams were stored. Not exactly a big or quiet place, but she must have had a reason. Or her sister, but Kairi wasn't his concern. Let Sora deal with her.
The curtains were drawn over the windows, so there was no telling what was inside from them. He didn't really need to tell, Sora had helped them unpack like the charitable soul he was. Well, if it gave him what he needed to know, it couldn't have been that bad.
A few glances around told him he was alone. Perfect.
The door was locked, naturally. It didn't stay that way after he'd given it a good, solid kick. It made a lot of noise, and damaged the door of course, but it got him in, so he slipped in before anyone noticed him.
Everything was neat and tidy, exactly as it had been when Sora had left. The kitchen looked completely unused, as did the bathroom.
The beds broke this rule of tidiness. One bedroom, with a bed on either side of the room. He ignored Kairi's, and went straight to Xion's, telling the difference because their names had been carved into the wood at the end of each. Maybe some people had trouble telling them apart despite their clearly different hair or something.
The beds were a mess, looking more like someone had been dragged out of them while struggling.
He picked up the covers, tidying them more because he was bored than out of any kindness to the girls. When he came to setting Kairi's straight, he found a note hidden inside it:
'Seifer:
Have girls safe at AM. Tell others not to worry. Don't let them find out.
Setzer.'
Too late, Roxas thought, pocketing the note. He'd keep it with his stash until he got the chance to act on it, probably tomorrow night.
So, Seifer was in on what had happened. No wonder nothing had been found. Who was Setzer though? Sora didn't seem to know anyone called Setzer.
Well, no matter. He could draw on what Sora knew and could do. What harm was there in giving him something back? Unaware of it's source, Roxas caused Sora to have a dream where he was outside the twins' house, overhearing Seifer reciting the note. Maybe it would spur Sora's curiosity when he woke up, and get him to go searching for him. Better that Sora waste the time chasing him up than him wasting the valuable hours he now had every night.
He paused often on his way back out, listening for anyone who might have come running after he'd kicked in the door, but there didn't seem to have been a reaction. Still, better to be cautious, so he surreptitiously looked out of one window to see if there was anyone hiding outside.
Damn!
Seifer was approaching. Clearly someone had gone to tell him. At least he was alone.
Well, the house was built so he could evade him it seemed. Two rooms at the front on either side of the door. The stairs and a corridor to the kitchen and dining room at the back. There was a door from each front room to the dining room or kitchen behind, and a door between both dining room and kitchen. No matter which way Seifer went, he'd have a way out.
Roxas hid behind the door from the kitchen down into the corridor, opening it just a crack to see which way Seifer would go.
He went straight upstairs. Roxas waited until the floor creaked right above him, signalling that Seifer was fully up the stairs, then quickly but quietly made for the door. He kept to the walls once outside, so Seifer wouldn't be able to see him so easily from any windows, upstairs or not.
He wouldn't find anything there anyway. Just a pair of tidied beds, and no note.
Maybe Seifer hadn't found the note in his first search. It had been tucked into the covers fairly well. Or maybe Seifer had tucked it there himself, not wanting anyone else to find it.
It didn't matter much now. He'd know someone had been there, but he'd never be able to find out who. Not once Sora woke up.
He felt Sora stir slightly, and headed quickly up a different side street to get back sooner. He climbed in the same way he'd left, stashing everything quickly, but neatly under the floorboard, ensuring the floorboard itself didn't look out of place before he settled back in.
Well, it had been a quick and quiet night. At least he had something to start with now.
Roxas leaned back on Sora's bed, getting comfortable.
Not long after, Roxas fell asleep...
