The acrid stench of gunpowder lingered in the air as Rei glared at the Tiger Girls, her fists clenched at her sides. The alleyway echoed with the fading sounds of their target's hasty escape, leaving both teams empty-handed and seething with frustration.

"Nice work," Rei spat, her voice dripping with sarcasm. "You just cost us both a big payday."

Snow, the icy-eyed white tiger hybrid, merely shrugged, her expression maddeningly calm. "Not our fault you weren’t your backs when we arrived.”

Beside her, Flake grinned, sharp canines glinting in the dim light. "Maybe if you spent less time singing and dancing at your stupid concerts, you wouldn’t be weak.”

Luna bristled at the jab, taking a step forward. "Why you little-"

Rei threw out an arm, halting her sister's advance. As much as she wanted to wipe those smug looks off the Tiger Girls' faces, starting a brawl in a filthy alley wouldn't solve anything. They needed to be smarter than that.

"This isn't over," Rei growled, locking eyes with Snow. "We're still the top hunters in this city, and don't you forget it."

Snow's lips curled into a wintry smile. "For now, maybe. But the way things are going, your reign won't last much longer."

With a dismissive flick of her striped tail, Snow turned on her heel and sauntered away, Flake close behind. Rei watched them go, her jaw clenched so tightly it ached.

"Come on," she muttered to Luna. "Let's get out of here."

The ride back to their penthouse suite was tense and silent. Rei's mind raced, replaying the botched capture over and over. If those damn twins didn’t surprise them, their target wouldn’t have the chance to escape.

"We can't let them keep getting the drop on us like this," Rei fumed. "Our reputation is on the line."

Luna nodded, her blue eyes clouded with worry. "I know. But they're good, Rei. Really good. What if..."

She trailed off, but Rei knew what her sister was thinking. What if the Tiger Girls really supplanted them as Moreau City's premier bounty hunters? What if all their hard work building their reputation came crashing down?

Rei shook her head, pushing the doubts aside. "No. We're better than them. We just need to step up our game."

By the time they reached their suite, some of the anger had faded, replaced by bone-deep weariness. Rei's muscles ached from the chase, and her head throbbed with the beginnings of a stress headache.

"I need to unwind," she sighed, rubbing her temples. "Jacuzzi?"

Luna's face brightened at the suggestion. "Oh yes, please. I feel like I've got alley grime in places I didn't even know I had."

They changed into their swimwear, Rei opting for a sleek red bikini while Luna chose a shimmering blue two-piece that matched her hair. The rooftop jacuzzi was one of the perks of their luxurious suite, offering panoramic views of Moreau City's glittering skyline.

As they settled into the warm, bubbling water, Rei felt some of the tension melt away. She closed her eyes, letting her head fall back against the edge of the tub.

"That's more like it," she murmured.

This story originates from Royal Road. Ensure the author gets the support they deserve by reading it there.

For a few minutes, they soaked in comfortable silence. But when Rei opened her eyes, she saw Luna's brow furrowed with concern.

"What's wrong?" Rei asked, though she had a feeling she already knew.

Luna bit her lip, hesitating before speaking. "I'm just... worried. About the Tiger Girls. What if they really do replace us? We've worked so hard to get where we are, both in our music careers and as hunters. If we lose that..."

The fear in her sister's voice tugged at Rei's heart. She hated seeing Luna upset like this. Impulsively, she reached out and poked Luna in the ribs, right where she knew her sister was most ticklish.

Luna yelped, jerking away. "Hey!"

Rei grinned, attacking with both hands now. "What's the matter, sis? Feeling a little sensitive?"

"Stop it!" Luna squealed, trying to fend off the assault while giggling uncontrollably. Water splashed over the sides of the jacuzzi as they tussled, their laughter echoing across the rooftop.

Finally, Rei relented, letting Luna catch her breath. Her sister's cheeks flushed, her eyes sparkling with mirth instead of worry. Mission accomplished, Rei thought with satisfaction.

"Feel better?" she asked.

Luna nodded, still grinning. "You're evil, you know that?"

"Maybe," Rei conceded. "But I'm also right. We're not going to let the Tiger Girls or anyone else take what's ours. I promise."

The determined set of Rei's jaw seemed to reassure Luna. She opened her mouth to respond, but before she could speak, a harsh electronic chime cut through the air.

Rei groaned, recognizing the tone of their secure communication line. Only a handful of people had that number, and a call this late usually meant trouble.

Reluctantly, she hauled herself out of the jacuzzi and padded over to where their holo phones lay. The caller ID made her eyebrows rise in surprise.

"It's Fiona," she told Luna, who was climbing out to join her. "Must be important if she's contacting us directly."

Rei activated the holographic display, and the stern visage of Moreau City's Chief of Police materialized before them. Fiona's emerald eyes narrowed as she took in their dripping swimwear.

"I hope I'm not interrupting anything important," she said dryly.

Rei fought the urge to squirm under that piercing gaze. Even after all this time, Fiona had a way of making her feel like a naughty schoolgirl caught breaking curfew.

"Not at all, Commissioner," Rei replied, adopting a professional tone. "What can we do for you?"

Fiona's expression grew grave. "I have a new assignment for you. One that could be the biggest challenge you've faced yet."

Despite her weariness, Rei felt a spark of excitement. This was exactly what they needed - a chance to prove themselves and put the Tiger Girls in their place.

"We're listening," she said.

Fiona's holographic form flickered as she pulled up a series of gruesome crime scene photos. Rei's stomach churned at the sight of mangled bodies and scenes of carnage.

"For the past week, something has been stalking the underbelly of our city," Fiona explained. "Whatever it is, it's unlike anything we've dealt with before. Victims have been found partially... consumed. Those who've survived encounters describe it as some kind of amorphous black creature, capable of changing its shape at will."

Luna gasped softly beside her, and Rei felt her own pulse quicken. This was far beyond their usual bounties.

"Why come to us?" Rei asked. "Surely this is a job for your officers."

Fiona's jaw tightened. "We've tried. Lost some good people in the process. Whatever this thing is, conventional tactics aren't working. We need your unique skills and... unconventional methods."

Rei did not miss the implied compliment. She exchanged a glance with Luna, seeing her own determination mirrored in her sister's eyes. This was their chance to reassert their dominance as Moreau City's premier hunters.

"We'll do it," Rei declared. "Send us everything you have on this creature. We'll start our investigation immediately."

Fiona nodded, relief clear in the slight relaxation of her shoulders. "I'm transmitting the full case file now. Be careful out there. This thing is like nothing we've seen before."

As the hologram winked out, Rei turned to Luna with a grim smile. "Looks like our relaxation time is over, sis. We've got work to do."

They hurried to dry off and change, the gravity of their new mission settling over them like a heavy cloak. As Luna fired up their high-tech planning station, Rei's mind raced with possibilities. How would they track this creature? What weaknesses could they exploit?

She was so engrossed in her thoughts that she almost missed the incoming call alert. Rei frowned when she saw the number - unlisted, but with a familiar prefix.

"Hello?" she answered cautiously.

"Well, well," drawled a silky voice that made Rei's hackles rise. "Heard you kitties got yourselves a new toy to play with."

Rei's grip on the phone tightened. "Snow. How did you get this number?"

The white tiger hybrid's laugh grated on Rei's nerves. "Oh, we have our ways. Just wanted to give you a friendly heads up - you're not the only ones after this bounty."

"What?" Rei sputtered. "How did you even know-"

"Like I said, we have our ways," Snow interrupted. "May the best hunters win."

The line went dead, leaving Rei staring at the phone in disbelief. She turned to Luna, who had caught enough of the conversation to guess what happened.

"The Tiger Girls," Luna said, her expression a mix of anger and worry. "They're going after the creature too."

Rei nodded, her jaw set in a hard line. "Looks like the race is on."

As they dove into their preparations, Rei's mind whirled with the implications. The stakes had just gotten even higher. Not only did they have to stop this mysterious monster, but they had to do it before the Tiger Girls could claim the glory.

One thing was certain - this hunt would push them to their absolute limits. And Rei was determined to come out on top, no matter what it took.
