In the deepening silence of the night, as Akira and Macau returned to their apartment, the air felt thick with an unsettling, heavy tension. Macau was utterly exhausted; her mind was so cluttered with the intricate details of files and legal cases that she craved nothing but a moment of peace. Yet, she knew Akira was far from sleep—the prosecutor sat fixed in her chair, staring at the documents before her with an intensity that suggested she was trying to force the hidden secrets right out of the paper. Hoping to clear the mental fog, Macau considered going over to see Naea for a brief reprieve, but she stopped in her tracks. Akira's rules were absolute and unyielding: no one visited Naea without her explicit permission, and if a visit did occur, Akira was to be there as an inseparable shadow.She looked at Akira. The prosecutor hadn't moved for an hour. Her pen moved with rhythmic, lethal precision, jotting down notes on the "Operation Lost Echoes" file.
"Akira," Macau said, her voice small in the vast quiet. "I'm going to see Naea."
The pen didn't stop, but its pace slowed, a microscopic hesitation. Macau knew the rules: No contact with Naea without permission. If you go, Akira goes.
"Do you want to come?" Macau pushed, searching for a flicker of humanity in Akira's frozen expression.
Akira didn't look up. Her posture remained cold, a statue of duty. She didn't say 'no,' but her silence was a fortress. Don't disturb the work. Don't mention her name. Macau sighed, understanding the unspoken rejection, and walked out.
The hallway was freezing. Macau stood before Apartment 44 and pressed the bell. She waited. Five seconds. Ten. The silence from inside was different—it wasn't the silence of sleep, but the hollow silence of an empty vessel. There were no footsteps, no rustle of sheets, no soft humming of a surgeon winding down.
"Maybe she's still at the hospital," Macau whispered to herself, a frown deepening on her face. She returned to Akira's cabin, her expression troubled. "Boss, Dr. Sato isn't home. I'm going to bed."The pen in Akira's hand stopped instantly. The nib dug into the paper, leaving a small, dark blotch of ink. A memory flashed in her mind: the parking lot. Naea's Mercedes Sedan had been there, parked in its usual spot. If the car was there, why wasn't she? Had she left for Osaka ?
The name Isamu Sato suddenly screamed in her mind. Was it possible? Was the sister of the boy she was hunting for the same woman who had just shattered her heart? She shook the thought away, forcing her hand to start writing again, though her heart was now hammering against her ribs like a trapped bird.Macau reached the door to her room but stopped. She turned back, watching Akira's hunched shoulders. "Akira boss... there's something that's been bothering me since last night. If you don't mind, can I ask?"
"Keep your excitement to yourself, Macau," Akira replied, her voice a razor-thin line of ice.
Macau didn't flinch. She took a direct shot. "Do you like Naea?"
Akira froze. She didn't deny it. She didn't move. She just stood there, a shadow in the dim light of the desk lamp. "What do you think?" Akira asked, her back still turned.Macau smiled sadly. "My heart is absolutely sure. Prosecutor Akira likes Dr. Naea."
The silence that followed was a confession in itself. Macau pushed further, her voice softening. "I think you confessed last night... and she rejected you. Didn't she?"
Akira finally turned. When her eyes met Macau's, the mask was gone. For a split second, Macau saw the raw, jagged pain Akira had been burying under layers of prosecution files. Macau tried to lighten the mood with a wink. "It's okay, boss! If not Dr. Naea, we'll find someone else. A beautiful girl, someone who fits you."
The temperature in the room seemed to drop ten degrees. Akira's voice turned into jagged glass. "I have no interest in 'relationships.' And as for Naea... I have liked her since Osaka, six years ago. If you ever mention another name in front of me again, you're fired. If it isn't Naea, it won't be anyone. Now, drop it."
Macau shivered. "Boss, if you want, I can talk to her—"
"No." The stare Akira gave her was enough to silence a courtroom. "Naea is intelligent. She makes her own choices. I heard her answer yesterday without her even saying a word. Now, go to sleep."
To Akira, it was a suggestion; to Macau, it felt like an absolute order that left no room for debate. Macau retreated to her room, the weight of the night's revelations still heavy on her mind, but after scrolling through her phone for a few minutes to numb the tension, sleep finally claimed her. Meanwhile, Akira remained a prisoner of her own thoughts, the names Naea Sato and Isamu Sato swirling in her head like a dark omen. She desperately tried to rationalize the connection as a mere coincidence, yet a nagging instinct told her otherwise as she finally succumbed to a restless slumber.
The next morning arrived with a cold, functional efficiency. Both women went through their morning routines like clockwork—freshening up and moving through the apartment in a synchronized but silent dance. Akira prepared breakfast while Macau brewed a pot of strong coffee, the aroma filling the kitchen, though the air between them remained thick with unspoken words. They ate in a heavy, contemplative silence, neither willing to break the truce of the morning. Once finished, Akira packed lunch for both of them, her movements precise and detached. They headed down to the parking lot where Akira pulled the car out of its stall. Macau climbed into the passenger seat without a word, and together, they drove toward the office,the office was a war zone. The air was thick with the smell of burnt coffee and the hum of servers. Together, Akira and Macau dove into the dark web's belly, and that's when they found it: "The Blue Butterfly Message."
It was a masterpiece of psychological warfare. An encrypted link sent to vulnerable teenagers with a single, haunting bait: "Do you want to see the real you?"
The moment a child clicked that link, a digital trap door slammed shut. Their location was pinged, and the hunt began. But the reality was worse than kidnapping. Akira's blood turned to slush as she read the details of "The Living Autopsy." The monster wasn't killing them. He was turning them into "Art"—replacing limbs with mechanical gears, fusing skin with cold steel while they were still breathing.
Akira's brilliance ignited. She didn't just look at the data; she looked for the soul in the machine. She mapped the last pings of the twenty victims, cross-referencing them with the server's latency.
"He's not in the city," Akira muttered, her eyes bloodshot but sharp. "He's at the edge."
The heat map converged on a single point: an abandoned server farm in the industrial outskirts of Tokyo. Akira grabbed her tactical jacket, the grief for Naea replaced by a murderous, focused rage. She checked the file one last time—Isamu Sato's photo stared back at her. He had Naea's eyes.
"Team, gear up," Akira commanded, her voice vibrating with authority. "We're going in. Every second we waste, another part of those kids is being replaced by iron. Let's move!"
