Prologue

She sat on his desk, looking down at his files with a flicker of disgust in her eyes. Chocolate-colored hair dripped over her shoulders as she craned her neck back, the door having been pried open. The woman frowned.

"Leon," she chided, "you're late."

The officer rolled his eyes at her with a sigh, brushing his long bangs from his eyes, fingers lingering over the scar on the bridge of his nose. He had gotten it when a violent suspect had tricked him into getting close enough to hit; needless to say, Leon Lionhart had learned his lesson. You don't trust criminals.

"Get off of my desk," he snapped.

"Oh, someone's grumpy!" The young woman, a detective and Leon's romantic partner, climbed off of the wooden stand, shifting on her feet as she watched him. She grinned, approaching. "Did you get sent on a goose chase again?"

"Yes." Leon pinched the bridge of his nose, settling in a chair by the door. His office was small – quaint and homey, but small – with white, newly painted wall and a bookshelf in front of what were once windows, and his desk.

His companion settled herself in his lap, arms loosely draping over his shoulders as she sighed, defeated. She nuzzled his neck. "Hm… tell me about it – before I'm forced to threaten you with a stapler again."

Leon chuckled, feeling quite embarrassed. The woman had, after finding him locked in his office (and somehow found her way into his safe-place), chased him around the room with a fully loaded stapler, screaming some choice words that were beautifully unlike her. He had gotten six staples in his walls, two in his shoes, and one loosely imbedded in his arm, to which she had gotten out when he'd explained to her why he had locked himself away.

"It's the same thing as yesterday, Kei," he told her, "someone hearing about a possible lead to finding a member of that group that's going around, murdering people. But, when I went to look, I found nothing."

Kei frowned, gently kissing his neck. He shivered in delight, and laughed at himself. "No offense, but shouldn't I be kissing you like that?"

"Yes… well, you're not going to like my news one bit," she replied, giving him a sharp, apologetic look. He groaned, shifting her forcefully and nipping at her neck until she squeaked in a bit of pain. "Le… not so hard…!"

He smirked. "Sorry – go on."

She purred a bit, humming a tune to herself before continuing on her topic; "there's been another murder – a boy, fifteen, was beaten and then drowned. Cloud found his body in the river this morning, on his way to work."

Leon sighed, resting his chin on her shoulder. "Have they identified the boy?"

"Roxas Gainsborough."

"Isn't that Cloud's punk?" Leon felt her nod, which beckoned him to continue. "Thought he was still in Juvenal for setting fire to that abandoned house down on 5th Street."

"That's what I was led to believe as well, but it turns out that Rox was let out for 'good behavior'. And now, a week after – by the date on his release forms – he's dead." Kei whined a bit, causing Leon to wrap her tighter in his arms, and she smiled at his action. "Rox also had a thing against water, remember?"

Leon searched his memory for a moment, before nodding. "Yeah, he freaked when we took he and his twin with us to the islands on that sailboat. I thought the poor kid was going to jump ship, but he looked to nervous to do that."

Kei and Leon had offered to take Sora and Roxas off of Aerith and Cloud's hands, because Leon's niece, Yuki, was very fond of the twins. The girl was going to meet them at the docks on Destiny Islands, and had failed to inform her uncle and aunt of the blond twin's horrible phobia of water; Roxas had been more than pleased to be on dry land again when they reached destination.

"Wait," the police officer growled, "is Cloud still in?"

Kei shook her head, "no. He went home, to console his wife and be there to tell Sora when he came home from school. I don't think either wife or son will take the news well…"

"We'll stop by after work tonight," he told her, getting an immediate nod.

The woman sighed. "Gods, whoever's causing these murders are sure good at it. Cloudy-boy said there wasn't a trace left of any DNA or murder weapon at the river."

"Did he bring back samples of what he found around the boy?"

"Yes – they've returned with negative results," Kei answered, "and they checked Rox for any help, and found nothing."

Leon sighed, feeling defeated already. They'd been on this particular case for months, ever since the first victim, a young, busty barmaid by the name of Tifa Lockheart, had shown up dead in the middle of nowhere, in a ditch that appeared to have recently been dug up.

Kei leaned back against him, playing with the file in her hands that held the information on the newest murder. "Le, I'm really starting to get disturbed by these cases."

"I know, Kei," the man told her, feeling the same. "But a job's a job."

He felt her get free, and watched her move away from him, pulling out her cellphone. Leon frowned. "Kei…" She ignored him, flipping it open and dialing a number that Leon couldn't read from his position. "Kei." Once more, he was ignored.

Leon rolled his eyes, getting up and stalking slowly, quietly, up behind her.

A whistle rang through the air, and Yuki's hands shot up over her ears. She glared at the soccer coach, her father, and growled low in her throat. "God, Dad," she shouted, "gonna go deaf over here if you keep blowing that thing so loud!"

Zack Fair laughed at his daughter, enjoying the scowl she sent him. "Then run, Yuki – just because you're mine, doesn't mean I'm not gonna tell you to get your butt in gear. What would your uncles think?"

"Cloud would scream; Angeal would lecture me about dreams and honor; and Leon would sit there and be lectured at by Aunt Kei for 'even thinking about scolding Yuki'." Yuki sent him a knowing smile.

Zack put the whistle to his lips, and proceeded to chuckle when his daughter literally sprinted away from him.

His phone rang, and he put away his 'weapon' to answer it. "Hello, Fair here."

"Hello, Puppy," Kei's silky voice purred on the other line. Zack subconsciously scowled at the petname, but said nothing, as he knew it would not cease her calling him it. "Listen, is Yu or So there?"

"Yeah, but they're both busy running laps and drills. Why – is something wrong, sis?" To Zack, it was habit to called Kei by 'sis', as he had grown a brotherly bond to Angeal Hewley, who was Kei's half-brother and close friend.

"Sora's brother was found dead this morning, in that lake close by Cloudy's house – you know the one? Such a shame; boy was one of your best players when he was on the team, wasn't he?" Kei sounded truly sincere, no matter how much she would tease him before by saying "soccer's a dog's sport", and that it fit him perfectly for said reason. "Cloudy headed home to console Aerith this morning… don't know how So will take it."

"He's a tough-y," Zack commented, "He'll be alright. Besides, he'll have Yuki and Riku to help him cope. And Kairi – that girl will be all over him, doing his every beck and call to make him happy again."

"Cutest little couple," she murmured.

He chuckled, nodding. "Yeah, they are cute together." The black-haired coach sighed, "hey, are you and Leon going over to the Strife's house anytime soon to pay respects?"

"After work tonight, why? Do you want to come, Zacky?"

"No, I want you to take Yuki over."

"Alright." There was a pause, and something that sounded like Leon trying to motion her from her phone. "Look, I gotta go – Leon's being a bugger again. Talk to you later, Pup."

Zack laughed, "knock him one for me, Kei!" He could hear her snicker, and then something that sounded like a lion growling and leaping at her, before she hung up (or, was forced to).

Zack drew out his whistle, blowing into it and sending a ring out. The players on his team jumped in a bit of fear and surprise. "Alright," he growled, "practice your scoring. Riku, Sora – you're goalies. Go!" The teenagers went to obey his command immediately. He sighed to himself.

"Jeez… you got some bad luck going to you, Cloudy."

Yuki kicked the ball towards Riku's goal, smirking as it slid past him and hit the boundary that was the net. The boy slammed his fist into the ground, displeased that the checkered ball had gotten past him. The girl, however, just laughed in triumph.

"Hooray," she cheered, giving a quick high-five to Yuffie Kisiragi. The shorthaired girl grinned back at her, before grabbing another ball and switching to 'attack' Sora.

Riku stood up, passing the ball back to his opponent. "Why's your dad looking so strange over there?"

Yuki looked over, noticing that Zack Fair did look extremely on-edge, but shrugged it off. "He's Zack," she told him, "when is he normal?"

The silver-haired boy chuckled, "yeah, you're right." He shook his head. "Silly me."

"Silly Ri-Ri," she agreed.

"Alright, switch goalies! Pick your substitutes, boys."

Riku sent her a look, mockingly bowing towards the goal as he stepped out. "After you, milady," he taunted. Yuki groaned, but obliged and walked by him, into place.

Sora had chosen to stay in the goal, much to Yuffie's enjoyment. The boy proved difficult to get a ball passed, as he and Roxas had raced a lot as children. Yuki could remember that it had made them both incredibly quick on their feet. It was something to brag about.

"Ready?" Zack called, not bothering to look up at his team. "…Go!"

And balls went flying.

Kei squeaked, trying to worm her way out from under Leon, who had her pinned to the floor. Her actions were to no avail, as the normally emotionless man was now becoming very playful. It wasn't to say that she didn't like his joy, but it was… overpowering; his agile movements didn't help her much in dodging him much, either.

The door flew open, causing both to pause their actions and look up. Angeal Hewley, Genesis Rhapsodos, and Sephiroth Crescent stood in the doorway, all seeming to be very amused. Sephiroth was the first to speak up; "are we… interrupting something?"

"O—Oh! N—No, nothing at… at all," Kei answered, scrambling out from under Leon; the cop was equally flustered.

Genesis scowled. "I certainly hope not! Kei, you are needed in our side of the building. Going to bring this cop a document does not give excuse to play dirty with him."

"We were not," the girl spat, "playing 'dirty'. He tackled me, and I wanted up."

"So you say," the redhead snapped back, glaring daggers at the officer. Genesis Rhapsodos had not been very fond of Leon since Kei had explained that she found great love for the man, and since Genesis had not been around her for twelve years, she had felt it right to 'move on'.

"Genesis," Angeal sighed, "let it go, please." The redhead visibly calmed, and the dark-haired man continued; "Kei, you and Leon may interact later, but you are needed to look over the evidence back in our office. It was irresponsible of you to run off as you did, but… understandable, as Roxas is practically your nephew; if anyone had right to show the file to the officer, it was you."

"Thank you, Angeal," the woman hummed.

"Now, shall we go?"

Kei gave her fiancé a quick peck on the lips before bounding past the three other detectives and out the door. The four men shared glances before Leon's bride-to-be's co-workers went after their more playful friend.

Leon chuckled, amused, and moved to his desk. His eyes fell to the clock; he and Kei could go see Mr. And Mrs. Strife within three hours – now, if the time would pass quickly, he'd be happy.

"Alright, practice is over for today. Shower, change up, and go home."

"Dad, that's not very nice."

Zack glanced at Yuki, who had approached him soon after she had taken her turn being goalie. He smiled, tussling her bangs. "I need you to go with your Aunt and Uncle tonight, alright? I'll drop you off at their office after —"

Yuki rolled her eyes, interrupting him, "I can walk."

"No, I want you to get a ride with me, Yuki. With these creeps running around and killing random people, I want you safe – and if you walk, I won't be sure," Zack told her. "Now, after you change up, get in the car and I'll drive you there."

The teen frowned, but nodded in her defeat. "Can Riku and Sora get a ride to their houses, too?"

"Of course – if no one shows up for them," the father offered. "But I'm sure Cloudy will come and get Sora, and Riku is probably going to hitch a ride with us anyway, because he's probably going to see his dad."

She nodded once more, running off to the bathrooms. Zack shook his head, chuckling when she disappeared, after almost tripping over her feet, into the doorways.

A knock came onto the detectives' door, and Sephiroth sighed. It was a long hour since they'd fetched Kei, who had ran off to hide in Leon's office; she and Genesis had yet to stop their bickering. Angeal was attempting to keep his sister relaxed by playing chess with her, and having given Genesis a copy of his favorite literature, but both actions seemed to be useless.

And now there was even louder knocking on their door, and it was really irritating Sephiroth.

The silver-haired man threw the door open. "Yes, what is – oh, hello Riku, Yuki. What brings you both here?"

"Zack wanted Yuki to come visit Kei and Leon, and Mom called after practice and asked me to stay with you," Riku answered, crossing his arms over his chest as he walked past his father. Yuki bounced after him, cheery, and settled next to Genesis.

"Hello Uncles," she greeted, smiling.

Angeal did not turn from his game, but smiled a bit nonetheless. "Good afternoon, Yuki – how was school?"

The girl sighed. "Boring as heck," she admitted, "even practice was dull… but I got a few past Riku!"

Riku whacked her over the side of the head, "stop saying that. Besides, you're terrible as a goalie anyway – every ball got past you."

Angeal chuckled at their antics; it was one of the reasons that he loved his niece and Riku when they were around. "Now, now, you two – where's your honor in those statements?" Both sent glares to his back, and he shook his head when he felt their eyes on him.

"There is no hate, only joy – for you are beloved by the Goddess," Genesis recited, looking at Yuki with a snickering glimmer of amusement in his azure eyes. The girl grinned, leaping at her uncle, and Genesis made quick to try to get free. "Yuki… Yuki, release me!"

"No," she laughed, "you brought it upon yourself, by calling me loved!"

Kei smiled, looking over at Riku, who was now speaking with his father. Yes, it was somewhat relaxing to have the two teenagers there, but with the evidence of Roxas' death hanging around on one of the desks… well, it would be more trouble than good.

A/N: Alright, other characters (i.e.; Kairi, Namine, Aerith, Cloud, more about Sora and Roxas, etc.) will be introduced in probably chapter one. Reviews are much appreciated.
