Neo-Tokyo was a city that never slept, a sprawling maze of steel and glass, its towering skyscrapers reaching for the stars, only to be anchored by the electric glow of the streets below. Neon lights danced across the buildings, flickering in brilliant shades of pink, green, and blue, advertising everything from high-tech implants to virtual dreamscapes. The air hummed with the quiet buzz of drone traffic and the distant hum of autonomous vehicles gliding through the city's arteries.

Rei Kuroda stood on the rooftop of an old building, one of the few relics left from the time before the world went mad. He scanned the horizon, his dark eyes narrowed against the harsh glow of the city. The wind tugged at his coat, causing the fabric to ripple like a ghost in the night. His hand rested on the hilt of his katana, a sleek, high-tech blade that pulsed with an inner light. It had saved his life more times than he cared to remember.

But it hadn't saved her.

"Got eyes on the target yet?" a voice crackled through his earpiece, pulling him back from the abyss of his thoughts.

Rei exhaled slowly, forcing himself to focus. He peered through the scope of his visor, his vision enhancing as he scanned the bustling crowds below. The streets were packed with people—workers returning home, gangs prowling for a quick score, and corporate suits moving in clusters, protected by their private security. He was looking for one person among thousands, a needle in a haystack of neon lights and concrete.

"Not yet," Rei replied, his voice cold and distant. "Keep monitoring the feeds. She'll show."

"Copy that." His handler's voice faded into static.

Rei's target was a high-level executive from MiraiTech, one of the largest corporations controlling Neo-Tokyo. They were powerful, ruthless, and had their hands in everything—from cybernetic enhancements to artificial intelligence development. People like that didn't disappear without a trace, not in a city as tightly controlled as this one.

But this particular target had vanished. She had gone off-grid, erasing her digital footprint with an expertise that made her hard to trace. That was where Rei came in. He wasn't just a bounty hunter—he was the best. Or at least, that's what everyone said.

Yet, as the minutes dragged on, Rei found himself wondering if the edge he once had was dulling. His mind wasn't as sharp, his focus not as clear. Too much time spent staring into the void of the past, drowning in memories of what he had lost. Memories of her.

Aiko.

He shook his head, pushing the thought away. No time for that now.

Suddenly, a flash of movement caught his attention. A figure darted through the crowd below, moving too fast, too precisely, to be an ordinary pedestrian. Rei's visor locked on, zooming in on the figure's face.

It was a woman, dressed in a long black coat, her hair pulled back into a tight bun. Her movements were calculated, her eyes sharp as she maneuvered through the crowd with ease. This was no ordinary target—this was someone who knew how to disappear.

"Found her," Rei murmured, the cold professionalism returning to his voice. He tightened his grip on his katana. "Engaging now."

He moved with practiced precision, leaping from the rooftop and landing silently in a narrow alleyway below. His muscles tensed as he began to follow the woman, weaving through the labyrinth of streets with the stealth of a shadow. Every step was calculated, every movement efficient.

But something about her seemed familiar. He couldn't shake the feeling that he had seen her before—perhaps not recently, but somewhere in the distant past. It gnawed at him, the ghost of a memory just out of reach.

Rei caught up to her as she slipped into a quieter part of the city, where the neon lights gave way to dark alleyways and flickering street lamps. He moved closer, his heart pounding in his chest, though he would never admit it. There was an electricity in the air, a sense of impending conflict.

"Stop right there," he called out, his voice steady.

The woman froze but didn't turn around. For a moment, silence hung between them, thick and tense.

"You've been running for a while," Rei said, taking a step closer. "But it ends here."

Slowly, she turned to face him, her features illuminated by the dim light of a nearby streetlamp. Her eyes were a piercing shade of green, sharp and cold, but there was something else there too—something vulnerable. It was that vulnerability that caught Rei off guard.

And then, it hit him.

It was her.

"Aiko?" The name slipped out before he could stop himself.

The woman—Aiko—blinked, her expression shifting just enough to reveal that she recognized him too. But she quickly masked it with a cold, detached gaze.

"So, you remember me," she said softly, her voice cutting through the air like a blade.

Rei's mind raced. He hadn't seen her in years—not since the war, not since the day everything fell apart. She had been on the other side, fighting for the corporations, while he had fought for what little remained of the free world. But they had shared something once—something deep, something that still haunted him.

"What are you doing here?" Rei asked, his voice barely above a whisper.

Aiko smiled, though it didn't reach her eyes. "That's a complicated question, Rei. The real question is—are you going to stop me?"

Rei's hand tightened on his katana, but he couldn't bring himself to draw it. The memories of their past—of the nights they spent together, of the promises they made—flooded back with overwhelming intensity. He had thought he could bury those feelings, lock them away in the depths of his mind. But seeing her again brought everything crashing back.

"I don't know," he admitted.

Aiko stepped closer, her gaze never leaving his. "Then you'd better figure it out quickly. Because the next time we meet, I won't give you a choice."

With that, she turned and disappeared into the shadows, leaving Rei standing alone in the dimly lit alleyway, his mind swirling with confusion and memories.

For the first time in years, Rei felt something other than cold indifference. It was as if a long-dormant part of him had awakened. But he didn't know if that was a blessing or a curse.

As the neon lights flickered overhead, Rei stood in the silence, haunted by the ghost of his past.
