Prologue: the secret WATERWAY
CHILD, i will hurt you


It may not have been a life worth living, but it was something.

There was nothing like having a family. People you could trust, you could rely on. And for Sora, orphaned at a young age along with many others whose parents died in the massacres. Children were spared. No one understood why. But as those children grew into adolescence, they learned that it was theorized someone, something out there had killed the adults in hopes of creating an army out of the children that were left.

Who knew? It was all just conspiracy theories created by idle minds.

The kids moved on in hopes of escaping their predicted fates of becoming someone's weapon, army, and moved to Traverse Town. Untouched where men and women and children lived happily.

The children, now a little bit older, had decided to create a home there. But the untouched city saw them as nothing more than pests, unwanted in their town. Their selfish, busy lifestyles led the kids to live underground, away from city life, living off the people's spoils, but at least they were all together.

For Sora and his friends, they had chosen to make their home, a place they liked to call the Secret Waterway. It was a tunnel, guarded by steel pipes that looked to be unmovable, Some may refer to it as the sewers, but to them it was home. As chilly and drippy as it did become in winter.

Winter had approached quickly, and now, the children had grown over the years between their old town and finding Traverse Town, as well as settling in. Teenagers now.

Riku had always said it was them against the animal known as society. Riddled with fleas. The townspeople may have disagreed, claiming the orphans the only fleas this town ever saw. But the group didn't need outsiders, as long as they had a home, food, and most importantly, each other. It was a family, their family, and that was all really mattered right?

That and the fact that they were alive. They felt alive. And it was better to be in their position with bruised palms and scraped knees than to, as Yuffie liked to put it, with a colon in your neck.

In the face of a new terror, it was better to be dead than undead, that was for sure.

It was obvious when someone was around the bend. Footsteps echoed louder through the cave, reverberated and bounced like the drip drops of ice. And it was always easy to judge, based on how hard or softly they walked, just who it was. In this case, it was Yuffie, with her way of stomping about in her heavy combat boots.

Riku and Sora, seated on old crates by the fire they made couldn't help but raise their head, nervous, aware of the fact that Yuffie was running. Fast. But then again, they thought as they shared a quick glance. Wasn't she always running somewhere?

She came in barreling, falling over herself into the thick moss-covered rocks that lined the secret waterway. She howled in pain, rubbing at her nose that dripped with blood. Drip. Drop. And she wiped at her nose, inspected her stained hand. "Oh shit," she said, in a hurried attempt to wipe it away. That was when she looked up at the trio of boys by the fire. Riku had already stood up. Blood. The scent of it could easily lead the monsters to them.

"Are you crazy?" Riku said, his voice low but harsh.

"I'm fine, thanks for asking," Yuffie stood up and blew the fallen bangs that fell into her dark eyes. They still managed to hold that innocence that belonged to children. Even if their childhood didn't leave room for puppies and tricycles. "I got the food." She said as she threw the paper bag she was holding onto the ground and cans rolled out on the slick ground. The boys' eyes trailed the can as it rolled. They were starving, after all.

"Well, good..." Riku said, though his eyes stayed planted on the waterway entrance. "Close it back up, before..."

"There's no monsters coming," Yuffie said with a wave of her hand, but she still did as asked and lifted the heavy iron bars so they could be placed at the arch of the waterway. That way, at least the facade of safety was present. "I outran them here—"

"What?!" Riku shouted so loud it caused Sora and the boy beside him, Tidus, to turn their necks so fast they nearly got whiplash. His voice echoed like cave drippings. Even the fire ceased to crackle and turn newspaper to ash. "You let them follow you here?! How could you be so fucking stupid?"

"Last time I checked, I'm one of the only ones here who does the food run," she turned her eyes to Sora and Tidus. Tidus wasn't fast enough, and in all honesty, was a bit of a chicken when it came to the monsters. Aladdin over on the side didn't want to risk dying and leaving his girlfriend, Jasmine, alone. Pathetic. And Sora? Well, Riku wouldn't even think about letting Sora go alone. Not under his watch. So it was left to Riku and Yuffie. And Yuffie had tried to quell her fear by turning it into a game of sorts.

"At least when I go, I don't try to play tag with the monsters," Riku growled as he picked up the cans and tossed them to Tidus and Sora. He pulled the switchblade out of his boot and proceeded to cut open the lid. "It's like your out looking for them."

"Psh, I'm fast. I can handle it." Yuffie walked over and tossed her soaked olive jacket to the floor. She sat on one of the crates and rubbed her hands together before holding them up to the fire. "What are you looking at?" She snarled at Tidus, who rubbed the back of his neck.

"Me? What did I do?"

Riku had trained to warn them all of the monsters. The were fast, much faster than Yuffie, and yet she always came back with stories about how she outran one this night and saw three the other night. But what she failed to see, most likely, as the monsters doing what they did best, feasting and slobbering on their prey. Sure, they all had heard Riku's horrific stories, but Riku was the only one who had seen it. He was the only one who really knew.

Ever since he was little, it was like he had a monster following him at a steady, safe distance. And it scared the hell out of him.

"Can't you stop being so reckless all the time?" He had been a ticking time bomb for a while now, and everyone had just been waiting for the night he'd explode. Yuffie was always doing crazy stunts, and if there was anyone who took it seriously, it was Riku.

The monsters weren't a joke, never had been. He remembered waking up in the middle of the night with Sora at his side, and he'd look to his surroundings. Wherever they were always depended on where they were sleeping that night. And he'd see these same yellow eyes. This same black silhouette that watched him, watched him, smiled. He'd close his eyes, as if that could will it away, eventually fall back asleep, and wake up as if his eyes had been casting strange shadows in his dreams.

"You're going to get yourself killed. Or worse, one of us!" He said.

"What do you mean 'or worse?' Geez, besides, I can handle them no sweat. They're no match for me-"

"Yuffie, get your head out of your ass and realize something...those things out there are monsters. They'll tear you apart just so much as look at you!"

"S'not like you care," Yuffie said, stubbornly crossing her arms over he chest and turning around on her makeshift seat to stare at anything that wasn't Riku.

"Riku."

Sora's voice was a lamppost against a pitch black night. Soft and comforting, it cut the edge off almost instantly. Riku glanced over to see Sora gesturing with a nod that they talk in privacy, and they stood up from the crates, moved the iron gates once again, and stood outside in the bitter, biting cold of another harsh winter.

"What?" Riku asked, already defensive as he wrapped his arms around himself and rubbed the sides of arms for some warmth. "I'm just worried," he said when Sora gave him that knowing look. Raised brow and a frown, that told Riku immediately that he hadn't handled himself as well as he probably could have.

"I know but she's your friend, and you just told her she's going to get torn apart."

"It's the truth," he looked down, his teeth chattering nosily. Small snow began to fall into his white blond hair, disappearing and weaving as if his hair was made from snow itself. He had never been one for the cold. "What if something happened to us because of her? I wouldn't even want to say I told you so."

There was a bit of a laugh that erupted from Sora, one of the little things that was a secret pleasure for the two boys. Laughter. It was one of the only things they had.

"Even on your dying bed, you'd say it."

And Riku smiled back, before he reached forward, and put his hand on Sora's shoulder, his face turning somber. "I don't want something to happen to you."

"I'll be fine. You'll be there to make sure nothing happens to us," Sora said with a grin, his lips beginning to tremble from the cold as well. He shuffled his feet, sneakers covered in old, dirty snow, and his tartan flannel was hardly enough to keep him warm, even if it was underneath the thick jacket Riku had let him borrow a little while ago.

Winter was always brutal, but now they had more than just the cold to worry about.

"Stop being so afraid, okay? I know what you saw was horrific but-"

"I'm not afraid. I haven't been afraid of monsters under my bed since I was a little kid," Riku said, his eyes narrowed. And he knew exactly what monster kept him up at night, though that was something he hadn't told Sora. "I'm just cautious. At least someone needs to be."

Sora sighed, soft, and though Riku was a bit of a hard-ass at times, he was right. Someone had to be the hard-ass in this group. It most certainly wasn't Sora.

"Come on, let's eat, I'm starving," Sora said as he grabbed Riku's hand, the gloves they wore moth-eaten and punched with holes, but there was a warmth there. A heartbeat Sora held in the palm of his hand.

And they walked inside, forgetting about monsters for the time being. Just for now, they could forget. Sora always had a way of making Riku forget.

There were times, for Riku, when he could easily forget his fear, his anxiety, his stress, and those times were few and far between, and Sora knew that.

When he had the chance, he'd give Riku that moment, made sure he bottled it up and relished the moment enough that he could forget monsters and winter and starving for just a few moments. An hour, tops.

And these were one of those moments, as Riku sat on a swing, laughing as he kicked his legs, and Sora pushed him from behind to give him more height.

He wanted Riku to feel like he was soaring.

Riku had even stopped insisting that they get back to the waterway, and seemed to be loss in the bliss of Sora's laughter that made Riku's heart pound against his chest, ring in his ears.

"If I push you any higher you're going to do a flip," Sora said with a laugh as he did just that, and pushed Riku even more. "Yuffie sure would be jealous."

"Yeah, she would, do it again," Riku said with a laugh, his bangs fluttering in his eyes, and he closed them, ignoring the bite of the wind that rushed at him every time he pushed himself forward on the swing.

They spent a few more moments laughing before Sora walked away, watching as Riku leaped from the swing and landed shakily on his two feet, before taking a wrong step, and falling against the white snow, his chest heaving.

Sora laughed, running forward and collapsing beside Riku, his arms strewn over Riku's chest as he nuzzled his nose against his neck.

"Clumsy," Sora said with a grin as he brushed some fallen snow out of Riku's hair, moon hair, Sora liked to call it before the moon became something to fear.

And though they were out now underneath the moon that hung in the midnight sky, their faces were flushed, their lips pink, as they laughed together in a way that they had never been able to stop doing.

"No monsters out tonight," Sora said with a grin, his nose tinged pink from the cold, and his cheeks tinged pink from Riku.

And Sora guessed he shouldn't have said anything at all, with the way Riku's face hardened, and all the laughter was replaced with that somber expression Riku always had whenever he was brought back to reality.

"Sorry, I shouldn't have mentioned it," he said as he scratched the back of his head and reached forward, pinching Riku's cheek. "Smile, come on, please. I didn't mean to make you think about it. Ugh, we were having so much fun."

Riku pushed his hand away, and moved to sit up, his hand raking through his hair, and Sora, desperate to go back to the way things were a moment ago, grabbed his shoulders.

"There's nothing out here, Riku. Just us. There's nothing-"

Sora stopped when he heard the soft creak of the metal swing behind, and he could have sworn all the blood drained from his face when he saw Riku's expression.

The higher you are, the harder you fall, and in that moment, everything came crashing down at their feet.

He didn't want to look, God, he didn't want to look, but Sora slowly turned around, heart beginning to pound when he saw a vampire perched on the swing like the gargoyle statues above the hotel in the second district.

The monster grinned, a fanged smile, and Sora swallowed the thick lump in his throat when he saw the monster's chin already smeared with blood. It stood up, lean and tall, casting a shadow over them, and Sora stumbled backwards on his hands, pushing himself away, kicking at the ground for propulsion.

Riku sat in place, trembling as he gaped, his body frozen in place, like all he could do was stare, stare, stare.

Sora grabbed his arm, and he glanced over for just a second, saw Sora's eyes pleading, mouth open, silent string of words coming out, though Riku couldn't understand. He couldn't do anything but stare as the monster looked back, and two more tall, lean figures joined him, hands clutching the chain as the monsters watched them.

He imagined their necks being cracked in two, and blood spurting out, and most of all he imagined Sora, looking to him, asking 'why? Why didn't you keep your promise?'

And he was snapped out of his trance, and turned to Sora.

"Should we fight?" He asked, a stutter in his voice, and his chin trembling.

"No, that's suicide. Just Run! Go!"

Sora finally managed to catch his footing, and stood up, pulling Riku along with him, who still kept his eyes on the monsters who watched with amused smirks.

They took off running, sprinting, and it wasn't long before they heard the monsters begin to run after them. They cried out, a battle call? A taunt? They weren't sure, but it was the most awful, blood-curdling sound the two had ever heard.

Sora looked at Riku, saw the expression on his face that he had ever seen before. Terror. A look of steadfast fear that made him run faster, against the burn in his thigh. Run faster against the sting in his chest as they ran for minutes now. Minutes without getting any farther from the monsters, minutes without getting any closer to their home. They ran without direction, without a single thought besides get the hell out of there, and live.

But Riku knew the vampires were just toying with them. He had seen them run so fast their body blurred, and they appeared so fast it was as if they didn't follow any rules the world had set for them. They could have easily been right in front of them whenever they chose. But why weren't they? Why were they letting them engage in a game of cat and mouse when it was clear who the winner was?

Was it cruel of Riku to fool Sora into thinking they could escape? There wasn't a way, right? It was impossible. But...Yuffie had managed to avoid them, maybe, maybe there was a bit of hope that could lead them home.

At least one of them.

"Go! Run faster, Sora! And don't look back, whatever you do!"

Sora nodded, he ran faster than he had ever imagined, God, it felt like he was soaring. Even when the bitter realization of pain and fatigue hit him. Like the burn in his chest, and the air whipping past his watery eyes and chapped lips.

But it felt different when his steps were fueled by adrenaline and fear. Fueled by the fact that his life was at stake.

He wasn't sure how long he would be able to do this for. Home was close, but would he really be able to outrun the vampires there?

But now wasn't the time to doubt himself. He knew there was no chance he wouldn't make it. Both he and Riku. He was focused, determined, and ignored every physical part of him that burned.

There was the turn up ahead. The turn that lead to the alleyway where home was. All he had to do was make it there. Just survive, make it there.

But, now that he thought about it, Yuffie and Kasu were there. Would the vampires follow him inside? Of course they would, so if they could, they had to have some sort of plan.

"Riku, we can't lead them to home. We have to shake them before that."

And there was no answer.

If Sora had looked back before, he would have noticed Riku's step slowing, would have noticed that Riku was stalling, was using himself as the distraction.

And a cry pierced through the air, ripped from the vampire's throat that made Sora stir. It sounded like a cry of victory, and when he turned his head, in the corner of his eye, he could see the vampires swarming.

"Riku!" He screamed, but didn't have time to turn back, when he suddenly felt himself falling, his foot catching something that sent him flying down a dark pothole. He screamed his friend's name again, all before his head collided with the hard ground, and his world went black.
