The museum halls were quiet. The red lights overhead pulsed softly, casting long shadows that shifted with every step.

  Yoru walked just behind the other three Sentari, keeping her movements measured and silent. She focused on matching their pace, keeping her breathing even. The lead Sentari at the front held the headset close, nodding occasionally as instructions filtered through the comms.

  They turned into a narrow hallway and stopped at a small, inconspicuous side room. Inside, a metal ladder stretched up toward a square hatch in the ceiling.

  The lead Sentari ascended first, boots clanging softly against the rungs. Yoru followed, the metal cool beneath her palms. When she pulled herself up through the hatch, she emerged into a cramped ceiling access space lined with grated flooring.

  She straightened slowly, aware of how small the space felt. There was a reinforced door set into one side of the structure. The lead Sentari approached it and tried the handle, but it didn’t move. He gestured to the other two, and the three of them braced their shoulders against the door, pushing in unison.

  After a few seconds, they stepped back.

  “The door won’t budge,” the lead Sentari said into the headset, wiping a hand across his brow. Even in the dim light, she could see the tension tightening his expression. “It’s heavily reinforced. We can’t risk kicking it in without damaging the generator.”

  There was a pause, then the lead Sentari’s gaze lifted suddenly and landed on something above. Yoru followed the line and spotted a vent high on the wall near the door, a narrow rectangular opening covered by a metal grate.

  “Confirmed. We’ll attempt that now,” he said into the comms.

  He motioned to one of the others. Bracing his back against the wall, he interlocked his hands to give the other man a leg up. The Sentari climbed, unscrewed the vent cover with quick, efficient movements, and carefully passed the metal panel down to the third man below before leaning forward to inspect the opening.

  “It’s too narrow,” the man said finally. “We won’t be able to pass safely.”

  The lead Sentari let him down and stood still for a moment, staring at the vent.

  “That vent’s the only other way to get to the generator,” he murmured, more to himself than anyone else. “If it’s really not possible, we’ll have to find another route. But there aren’t many other options.”

  Yoru looked at the vent again. She stepped a little closer, tilting her head to better judge the dimensions. From where she stood, it looked small—but if she got on all fours, flattened her shoulders, and moved slowly…

  “I think I can fit,” she said quietly.

  The other three Sentari turned toward her at once. The sudden weight of their attention made Yoru’s heart jump, but she kept her posture steady, expression composed. The lead Sentari studied her for a moment, gaze assessing.

  “Would you be willing to go in?” he asked.

  Yoru nodded. “If there’s no other way,” she said evenly, “I can try.”

  There was a brief pause as he considered her. Then he gave a decisive nod. “All right. We’ll leave it to you.”

  The lead Sentari removed the headset and stepped toward her, holding it out. Yoru accepted it carefully. When she placed it over her ear and adjusted the mic, the ambient hum of the cramped ceiling space faded away. The world narrowed to the soft static of the line.

  She touched the mic lightly. “Hello?”

  There was the faintest pause. Then a voice came through—calm, familiar, unmistakable.

  “Hey, Yoru.”

  Her breath caught. She straightened without realizing it, heart skipping in a way it only ever did at the sound of him.

  “Akio?”

  “Yeah. It’s me,” he replied. His tone was steady, grounded. “How are you feeling?”

  Yoru swallowed, one hand still resting lightly against the headset as if to make sure it was real. “I’m okay. What happened to the security guard?”

  “He had a sudden health emergency,” Akio said. “But don’t worry, he’s going to be fine. I’ve taken over comms for now.”

  Relief threaded through her, quiet but tangible. She stepped toward the wall as one of the Sentari braced himself beneath the vent. Yoru placed her foot into the makeshift foothold and rose carefully, steadying herself against the wall until she was eye level with the narrow opening.

  “Have you been guiding us this whole time?” she asked, keeping her voice level.

  “I have,” Akio answered. “And I’ll guide you through the vent and the reset procedure. Does that sound all right?”

  Yoru looked into the darkness of the vent. It was tighter up close. The metal interior smooth but uninviting, the space beyond swallowed by shadow. Her pulse quickened faintly at the thought of crawling through. But the knowledge that he would be guiding her, step by step, eased the sharpest edge of her nerves.

  “Yes,” she said softly. She drew in a deep breath, pressed her palms against the cool metal frame, and shifted her weight forward. “I’m going into the vent now.”

  “Got it,” Akio replied immediately. “Move slowly. If you get scared, let me know. I’m here.”

  Yoru lowered herself onto her hands and knees and eased into the vent. The metal frame brushed against her shoulders as she angled herself sideways.

  She began to crawl. Her palms slid forward, knees shifting carefully to avoid scraping too loudly. The faint red glow from the emergency lights behind her faded inch by inch until the darkness ahead swallowed it entirely.

  “Yoru,” Akio’s voice came through the comms, calm and clear despite the static. “There should be a grate ahead that drops down into a room below. When you see it, let me know.”

  “Okay,” she replied softly.

  She continued forward until a faint sliver of light appeared ahead. Relief flickered in her chest. Crawling closer, she saw it clearly—a rectangular grate beneath her, dim light seeping up from the room below.

  She shifted carefully to the side and peered through the slats. A small, cylindrical room waited beneath her.

  Reading on this site? This novel is published elsewhere. Support the author by seeking out the original.

  “I see it,” she whispered into the mic.

  “Good,” Akio replied immediately. “There should be screws along the side. Loosen them and lower yourself down. It’s not too high.”

  Yoru nodded instinctively. She reached for the screws, fingers working carefully in the cramped space. When the last screw came free, she steadied the grate with one hand and eased it aside. A faint rush of cooler air brushed her face. She lowered herself through the opening, gripping the edge and letting her body hang briefly before releasing.

  Her boots hit the floor with a soft thud. She wobbled slightly, knees bending to absorb the impact, one hand pressing against the curved wall to steady herself.

  “I’m inside,” she reported.

  “You should see a hatch in the center of the floor,” Akio said. “Open it. The power generator will be underneath.”

  Her gaze swept the room and landed on a circular hatch set flush into the floor. She crossed to it and knelt. The metal latch was heavier than she expected, and it opened with a low mechanical groan. Beneath it, embedded into the structure of the building, was a cylindrical generator core. It hummed faintly, vibrating with contained energy.

  “It’s open,” she said.

  “Great job. The next part is a little tricky,” Akio replied, tone shifting into focused clarity. “So listen closely, okay?”

  Yoru straightened instinctively, sitting back on her heels, attention sharpening.

  “To reset the generator,” he said slowly, “turn the handle on top and pull the core out completely. Once it’s out, there will be three switches on the left side. Flip the middle one. That will cause a secondary handle beneath it to pop out. Pull that handle up and reattach its end to the node across from it. It will click when it locks into place. Then push the handle and node back into the generator housing and reinsert the core into the floor.”

  Akio paused, giving her space to process.

  “When you remove the core,” he added, voice steady but deliberate, “it will cause a temporary blackout. You’ll need to complete the reset within three to four seconds.”

  “What happens if I can’t?” she asked, keeping her voice controlled despite the faint pressure building in her chest.

  “It… would complicate things,” Akio said carefully. “But it’s not anything that can’t be fixed.”

  Yoru stared down at the generator handle, the time limit pressing against her ribs. Akio had said it wasn’t anything that couldn’t be fixed—but the careful way he’d phrased it lingered in her mind, like there was more he wasn’t saying.

  Her throat felt dry.

  “How will I know when four seconds is up?” she asked, her voice quieter than she intended.

  “Just count each step in your head,” Akio replied steadily. “That’ll give you a good sense of timing. Don’t rush it—just stay consistent.”

  Yoru tightened her grip on the headset, as if anchoring herself to the sound of him. “Will you help me if I forget?”

  There was the smallest pause.

  “The blackout will affect network signals too,” Akio said gently. “I won’t be able to reach you while the power is down.”

  Yoru inhaled sharply. For the first time since entering the vent, the reality of it landed fully. She would be alone. In the dark. On a timer. With no voice guiding her through it. If she messed up, everyone would stay trapped.

  Her breath caught in her chest, sharp and shallow. She suddenly had the urge to shrink, to step back, to hand this responsibility to someone more experienced.

  “I—I don’t think I can do this,” she whispered, clutching the headset tighter.

  “Hey,” Akio said softly, the warmth in his voice cutting through the spiral. “It’s okay. Let’s go through the steps together again. There’s no rush. You can try when you feel ready, all right?”

  Yoru swallowed and nodded, anchoring herself to his voice. They went through the sequence slowly, and she practiced the motions in the air above the generator—following his rhythm, counting under her breath. Each repetition made the steps clearer in her mind, but the anxiety never fully left.

  Eventually, there was nothing left to rehearse.

  Yoru looked down at the generator embedded in the floor. The handle waited beneath her hovering hands. She swallowed.

  “I… I’m going to try now,” she said softly.

  “You’ve got this,” Akio replied, steady and certain. “It’s just like we practiced.”

  Yoru closed her eyes and drew in one long, steady breath. She recounted the steps in her head again, slowly, deliberately, anchoring each motion to memory.

  Just like we practiced.

  And before she could change her mind, she opened her eyes and pulled the core free.

  The room collapsed into darkness and suffocating silence. For a split second, the sudden absence of sound disoriented her. Her heart slammed violently in her chest, loud in her ears. But she forced her body to move.

  Her free hand slid along the left side of the generator housing, fingers searching in the dark until they brushed against three raised switches. She found the middle one and flipped it with a soft click.

  One.

  A sharp mechanical snap answered her, something shifting deep within the machine. She moved immediately, hand dropping lower along the surface until she felt the secondary handle protruding outward. She gripped it and pulled it up toward her.

  Two.

  Her palm skimmed along the generator casing until her fingers found the small exposed node across from it. She adjusted carefully, aligning the handle’s end with the slot she could not see, relying entirely on touch. It locked into place with a soft but distinct click.

  Three.

  She pressed her palm against the top and pushed. The handle slid smoothly back into the generator housing with another decisive click. Without hesitation, she grabbed the core and drove it back into its chamber, feeling its weight slide into place beneath her hands. She secured it, locking the floor handle firmly back down.

  Four.

  Yoru stayed frozen in the dark, heart pounding so hard she thought she might black out from the force of it. The seconds stretched unbearably, and doubt crept in as everything remained painfully still.

  Did it work? Did I miss something?

  Then—

  A low vibration returned beneath her palms.

  Light burst back into the room, glowing a soft white. The hum of restored systems echoed through the walls as distant machinery powered back online.

  She blinked against the sudden brightness, momentarily disoriented. Before she could fully recover, a heavy metallic sound rang through the room. The reinforced door swung open, and the three Sentari stood there, faces lit with relief and excitement.

  “You did it!” one of them exclaimed, grinning broadly. “The power’s back—great work!”

  Yoru felt relief flood through her like a wave. She nodded quickly, almost shyly, unsure what to do with the praise. Only then did she realize she was still wearing the headset. The line was dead, so she slipped it off slowly.

  By the time they returned to the main entrance hall, daylight streamed freely through the tall windows. People emerged from reopened wings, confused but safe, voices returning to their normal volume.

  Yoru was still taking everything in when her eyes drifted instinctively toward the holographic map terminal.

  Akio stood beside it, posture relaxed, hands loosely at his sides. He looked calm, composed, almost gently detached as a small group of people nearby helped the security guard carefully to his feet. He listened as someone spoke to him, nodding politely.

  Then, as if sensing her attention, he looked up, and their eyes met across the crowd.

  Something in her chest swelled so suddenly it nearly stole her breath. Without fully deciding to, Yoru found herself walking toward him. The noise of the hall blurred at the edges as she weaved through clusters of people. When she reached him, she stopped just at his side, close enough to feel his presence.

  Akio smiled. “You did it, Yoru,” he said quietly. “That was amazing.”

  The praise hit harder than she expected.

  “Thank you,” she managed, lowering her gaze briefly. “I couldn’t have done it without you.”

  He shook his head slightly. “I could only guide you. In the end, it was all you.”

  The certainty in his tone made her chest tighten in a completely different way. Pride flickered there, intertwined with gratitude, relief, admiration… and something softer she didn’t dare name. For a moment, she was simply content to stand beside him, letting the warmth of the moment settle into her bones.

  Their quiet bubble dissolved when footsteps approached. The lead Sentari stepped forward first, followed by the security guard and a well dressed man Yoru assumed must be the museum curator.

  “On behalf of the museum,” the curator said respectfully, “I want to formally thank you both. Your quick thinking prevented what could have been a very serious situation. We’re deeply grateful.”

  The security guard looked directly at Akio, emotion thick in his voice. “You saved my life. And you took control when I couldn’t. I won’t forget that.”

  The lead Sentari turned to Yoru, a proud smile breaking through his usually steady composure. “Resetting an EQ4 under pressure, especially for the first time, is no small feat. You should be proud of yourself.”

  Akio glanced at her then and added, without hesitation, “Yoru was the real hero today.”

  Heat rushed to her face.

  She stood there, absorbing the words as if they belonged to someone else. She had crawled through the vent. She had pulled the core. She had worked in the dark. People were standing here because she hadn’t frozen. All of it felt surreal.

  The curator smiled broadly. “As a token of our gratitude, please accept free admission to the museum for life.”

  Akio dipped his head politely. “Thank you. That’s very generous.”

  Yoru blinked, still catching up. “Th-thank you,” she echoed softly.

  After a few more exchanges, the group dispersed, leaving the two of them standing beneath the fossil once more. Yoru looked at Akio again, memory replaying in her mind—the darkness, the silence, his voice steady in her ear. The thought made her heart flutter all over again.

  “Um, Akio?” she asked, fingers lightly fidgeting with the edge of her sleeve.

  He turned fully toward her, attentive as always. “Yeah?”

  She hesitated only a second before forcing the words out. “Can we… do this again sometime?”

  For a heartbeat, she worried she’d been too vague. But Akio only smiled in that easy, reassuring way of his.

  “Of course,” he said. “You can find me anytime.”

  The simple answer lit something inside her so brightly she had to look away to steady herself. She fell into step beside him as they walked toward the exit, sunlight spilling across the stone floor ahead. Her steps felt lighter.

  And for once, so did her heart.
