The Guardian was down, but the Observers remained.
They leveled their weapons, closing the circle with military precision. Their rhythmic footsteps echoed through the chamber, drawing nearer with every beat. Harsh floodlights stung Koyoi’s eyes, blurring her vision into a white haze. The machine’s hum rose to an angry thrum, making the floor shudder beneath her feet.
"Don't let them escape," the Captain barked. "Secure the subjects. They’re specimens."
The space felt smaller as they closed in. Koyoi tightened the drawstring of her pouch, feeling the Wind Spirit tremble inside. She was terrified, but she couldn't stop.
"Tch... they're persistent," Asahi muttered, readjusting his grip. His footing was unsteady and his breath came in ragged gasps from the fight with the Guardian, but his blade never wavered. Watching him, a flame sparked in Koyoi’s chest. She couldn't just be protected anymore. It was her turn.
She looked at the massive machine. As long as it ran, the Observers would keep coming, and the earth would continue to weep. Blue light pulsed through the pipes at its base like glowing veins. If I sever those, the mountain will be free. She bit her lip.
"We have to break it," she said, her voice steady despite the tremor in her hands. "Destroy that, and they'll run."
Asahi nodded, leveling his sword at the machine. "But how? That thing looks solid."
"I'll ask the Spirit," Koyoi replied. She pressed her hand to the pouch. I know you're scared, she whispered in her heart. But if we don't help now, they’ll steal everything. A puff of warm air brushed her palm in response.
She opened the pouch. The Spirit was ready. "Wind, please! Tear those pipes apart!"
『...Leave it to me!』
The Spirit surged out, a tiny dust devil swelling into a massive vortex. It spiraled around the room first, kicking up grit to blind the Observers and rattling their lights. Koyoi felt its intent—it was shielding them while locking onto the target.
"What is this!?" the Observers cried as they were swept off their feet. The Captain reached for his console, but a focused gust slapped his arm away. It wasn't just a storm; it was a protective will. Within the vortex, Koyoi felt the Spirit give a small, brave laugh. It was giving everything it had.
The vortex charged the machine. Pipes groaned and shrieked as they were torn free. Steam hissed, sparks showered the floor, and the tower began to tilt. The light on its surface flickered into chaos.
"Cooling system failure!" someone screamed. "It’s going critical!"
With a roar, the machine crumbled. Blue light erupted from the wreckage, racing across the floor as steam geysered from the cracked earth. Then, a pillar of light shot upward.
The leylines. The stolen energy was being liberated all at once. The light pierced the ceiling, turning the rock translucent. Koyoi’s hair stood on end as the Spirit let out a jubilant cry. For a moment, the cave was as bright as noon.
"Evacuate!" The Observers scattered. Koyoi saw the Captain clutching his equipment even as he retreated, but she quickly turned away. Survival came first.
"Move!" Asahi grabbed her hand, pulling her through the collapsing tunnels. Rocks crashed behind them as they ran. When debris blocked the path, Asahi hacked through it. Koyoi didn't stop, clutching her pouch as the Spirit swirled ahead, guiding them through the gaps.
They burst outside just as an explosion thundered behind them, burying the entrance. Koyoi collapsed onto the grass, gasping for air. The scent of damp earth was sweet, the underground heat dissolving into the cool night. They lay there, trembling with exhaustion and relief.
Koyoi felt the pouch lighten as the Spirit slipped back inside. "Welcome back," she whispered. Asahi propped himself up, wiping blood from a cut on his forehead.
"...Is the mountain saved?"
At her question, he looked at the sky and nodded. "The earth is breathing again. It’ll be okay."
An aurora-like glow spread across the sky—the light of the released leylines. It shimmered as if the earth were taking a deep breath of relief, tinting the clouds with soft hues. Koyoi watched in awe. This was the color of the life that had been stolen. As the glow faded, the forest began to wake. A bird chirped; the wind rustled the leaves. The silence of the dying mountain was gone.
『...Thank you.』
She heard the voices of spirits on the breeze. Koyoi laughed, her face streaked with mud and tears. It had been terrifying, but they had saved it.
Asahi looked at the sky. "We did it." It was a small victory, but the mountain was free.
Distant thunder rumbled, sounding more like a song than a threat. Koyoi vowed to bring this same wind to the next town.
"Let's go," Asahi said.
Koyoi stood, brushing mud from her knees. The summit was still far, but she felt the wind at her back. She looked at the buried tunnel one last time. I won't let them take anything else.
The wind stirred the grass, a signal for the next trial. Koyoi found her footing and began to walk. With the Spirit’s help, her fear began to thin and her pace grew light. With the wind as her ally, she knew there was only one way to go: forward.
