The gas masks were finally finished, each one carefully crafted with Kaseki's expert hands and Senku's meticulous design. They lay in a neat row on the workbench, their dark frames gleaming under the dim light of the workshop. The air was heavy with the knowledge of what came next: the sulfuric acid lake, a place of death and danger, and the next critical step in their mission.
Senku stood at the center of the group, his arms crossed and his expression resolute. "I'll go alone. There's no need to risk more lives than necessary."
"No way!" Chrome shouted immediately, stepping forward with a determined look. "You're not going alone, Senku. We're in this together."
Senku sighed, already preparing a rebuttal, but Kuri's calm voice cut through the tension. "Chrome's right. We're comrades. Either we all go together, or we don't go at all."
Senku turned to her, his brow furrowed. "You're saying you'd risk your life for this? Why?"
Kuri shrugged, her silver eyes steady as they met his. "Because that's who I am. I'm kind of a ride-or-die, Senku."
The words hit him harder than he expected. For a moment, he was caught off guard, his heart skipping a beat. Ride-or-die? For me? Her unwavering gaze and the conviction in her voice sent a jolt through him, a mix of surprise, admiration, and something else he couldn't quite name. He swallowed, trying to push past the unexpected heat rising to his face.
"Well, that's… ten billion percent insane," he muttered, but his voice lacked its usual sharpness. "Fine. We go together."
The group set out early the next morning, the sulfuric acid lake looming in the distance like a shimmering mirage of death. The air grew thick and noxious as they approached, their gas masks firmly in place. The green, bubbling surface of the lake reflected the overcast sky, a reminder of how dangerous this mission truly was.
"Stay sharp," Senku said, his voice slightly muffled through the mask. "We're here for sulfuric acid, not a swim."
The group moved cautiously, collecting samples with the tools they'd brought. Senku worked with practiced efficiency, his focus unshakable as he transferred the dangerous liquid into a secure container. Chrome and Kuri worked alongside him, their movements careful but determined.

The bubbling green surface of the sulfuric acid lake hissed as toxic fumes rose into the thick air. Senku and the group worked quickly, their gas masks shielding them from the deadly vapors. Senku's sharp focus was locked on the task, transferring the acid into secure containers while barking instructions to Chrome and Kuri.
"Careful with that, Chrome! If even a drop spills, we're toast," Senku warned, his muffled voice cutting through the noise of the hissing lake.
Chrome grinned nervously, wiping his brow under his mask. "Yeah, yeah, I got it!"
Kuri moved methodically, her silver eyes darting between her comrades. She glanced at Senku, her gaze lingering for a moment longer than necessary. He's always so precise, so in control, she thought.
They were nearly done when it happened.
Chrome stepped back to adjust his footing, but the unstable ground near the lake's edge crumbled beneath him. He stumbled, his arms flailing as he toppled forward toward the bubbling pool of death.
"Chrome!" Kuri screamed, her voice ringing with panic.
Senku's head snapped up, his heart lurching. Without thinking, he thrust his hands forward, his mind focusing on Chrome with an intensity he didn't know he possessed.
And then, everything stopped.
Chrome hung suspended mid-air, his body frozen in place just inches from the lake's surface. The world around them seemed to hold its breath. Senku's fingers trembled, golden light flickering faintly around his hands as he struggled to keep his concentration.
"What the—?" Senku muttered, his voice barely audible through the mask. His sharp mind raced, piecing together what was happening. This… this is me. I'm holding him.
"Don't lose focus, Senku!" Kuri's voice jolted him back, cutting through his shock. She was sprinting toward Chrome, her movements swift and precise.
"Kuri, no! You're not wearing a mask!" Senku shouted, panic flooding his voice.
"I'm fine! Keep holding him!" she yelled back, her tone fierce. "I'll get him out!"
Senku's breath hitched, his fingers twitching as he maintained his focus on Chrome. Time seemed to drag, every second stretching into eternity as Kuri closed the distance. Her legs glowed faintly with magic, her speed accelerating as she reached Chrome's frozen form.
With a burst of energy, Kuri tackled Chrome, knocking him safely away from the lake's edge. They hit the ground hard, rolling to a stop a few feet from the bubbling acid. The golden light around Chrome faded as Senku dropped his hands, his body sagging with relief.
Kuri helped Chrome to his feet, waving at Senku to signal that they were okay. "We're fine! Get back to the samples!"
Senku didn't move, his chest heaving as he stared at his trembling hands. The golden light was gone, but the memory of it burned in his mind. That was magic. My magic.
He looked up, his sharp eyes locking onto Kuri as she dusted herself off. His rational mind screamed for answers, demanded an explanation for what had just happened. But those questions died on his lips. All that mattered was that his friends—she—were alive.

Back at the workshop, the atmosphere was tense as the group processed what had happened. Senku placed the sulfuric acid containers on the table, his hands still trembling slightly as he turned to Kuri.
"What was that back there?" he asked, his voice uncharacteristically quiet. "I… I held him. That was me."
Kuri nodded, her expression calm. "It was. Molecular Immobilization. You used your magic, Senku."
He stared at her, disbelief flickering in his sharp eyes. "How? I didn't even know I could do that."
"You've always had it," Kuri said gently. "Magic is tied to intent and focus. You wanted to save Chrome, and your instincts kicked in."
Senku's mind raced, piecing together what she had told him before. "So, it's not just theory. It's real."
"Very real," Kuri said with a faint smile. "But magic requires balance. It's not limitless, and it's tied to your emotions. That's why you need to stay in control."
Senku leaned against the table, his sharp mind still reeling. His gaze drifted to Chrome, who was sheepishly rubbing the back of his neck.
"Thanks for saving me, Senku. And you too, Kuri," Chrome said, his voice thick with gratitude. "That was… intense."
Kuri chuckled softly. "Let's try not to make it a habit."
Senku's eyes flicked back to Kuri, something unspoken passing between them. The memory of her rushing toward Chrome, risking herself without hesitation, played in his mind like a broken record.
For once, his endless curiosity wasn't focused on the how or why of magic—it was on the girl who had shown him what it meant to truly put everything on the line. And for the first time in his life, Senku Ishigami was at a loss for words.
