My Unique Adaptation Skill in Another world-Chapter 16 - 15: Foundation

Leo woke to sunlight streaming through the porthole and the gentle rocking of the ship. His body felt stiff, not from injury, but from a day of adjusting to ship life. He stretched, feeling joints pop, then dressed and headed topside.

The deck was already active. Crew moved about their tasks with quiet efficiency, adjusting rigging and checking supplies. The morning air was crisp, carrying the sharp scent of salt and open water.

Near the bow, Iori stood alone.

She moved through a series of forms; fluid, precise, deadly. Her twin katanas flashed in the morning light as she transitioned between stances, each movement economical and controlled. No wasted motion. No hesitation.

Leo watched, transfixed. This wasn’t sparring or combat. This was mastery.

She finished the sequence and sheathed both blades in one smooth motion, then turned and caught him staring.

"Enjoying the show?" she asked, one eyebrow raised.

Leo didn’t bother hiding it. "Learning, actually."

"Learning requires more than watching." She gestured for him to approach. "Though I suppose watching me isn’t the worst way to start your morning."

"Definitely not," Leo said, joining her near the railing.

Iori smirked faintly. "You wanted something, or are you just here for the view?"

"Both," Leo admitted. "But mostly—I need your help."

"With?"

"Aura." He drew one of his blades—Defiance—and held it loosely. "I’ve realized that my control is not good and I’m wasting energy, mostly just relying on raw power."

"Well you aren’t wrong," Iori said, studying him. "But considering how things have been and the different circumstances, you’ve done quite, but it won’t take you far"

"I know." Leo met her gaze. "That’s why I’m here, I want you to teach me."

Iori tilted her head, considering. "You understand I can’t teach you any of my techniques, They are exclusive to the First House."

"I’m not asking for your secrets," Leo said. "Just the foundation, theory, whatever you’re willing to share."

She was quiet for a moment, then nodded. "Alright then, but if I’m doing this, we do it properly, no half-measures."

"Agreed."

"Good." Iori pushed off the railing and moved to the center of the deck, gesturing for him to follow. "First lesson, is to understanding what aura actually is."

Leo joined her, sheathing Defiance.

"You’ve been using aura instinctively," Iori began. "Flooding your body with it to enhance your body, It works, but it’s inefficient"

"Aura isn’t just raw energy," she continued. "It’s the manifestation of your will, your life force, channeled through your body. The better you control it, the less you waste, and that efficiency is what separates mediocre fighters from true warriors, aside from techniques of course"

"Technique?" Leo asked.

"After you’ve mastered control. Techniques are physical anomalies created by manipulating aura in specific ways, like bending, warping or compressing space, creating shockwaves, heating up or cooling down your environment, increased perceotion that seems like future sight, and so many more, but attempting them without a proper foundation will just cripple you." Iori said.

She stepped closer, eyes sharp. "Right now, you’re at three stars in aura, which is respectable for most people our age, but progression gets harder with every rank. Going from three to four stars will take months, maybe years, depending on your talent and training, and the gap in power between ranks grows exponentially."

Leo absorbed that. "So even if I reach four stars, someone at five would crush me almost effortlessly?"

"Not necessarily," Iori said. "That’s where skill and technique matter. Two fighters even at the same rank can be worlds apart in actual strength. Efficiency, precision, mastery of their abilities, that’s what decides real fights, your star rank is just a measure of how much energy you have at your disposal, and that capacity determines what is accessible to you."

She drew one of her katanas, holding it casually. "I’m an eight-star aura user, you’re three stars, but even if you reached nine stars tomorrow, I’d still beat you, because I’ve spent years refining my control and gaining experience in applying all my skills and techniques."

Leo felt the weight of that. "So what do I need to focus on?"

"Basics," Iori said simply. "Aura flow, controlled enhancement, learning to channel power precisely instead of flooding everything at once." She gestured with her blade. "And sparring. Lots of sparring."

"I can handle that."

"We’ll see." Iori’s smile turned sharp. "Draw your blade."

Leo pulled Defiance free, settling into a ready stance.

"Show me how you fight," Iori said, her own blade held loosely at her side.

Leo didn’t hesitate. He pushed aura through his body and lunged forward, Defiance cutting toward her in a heavy diagonal slash.

Iori sidestepped effortlessly, her blade tapping his wrist as he passed. "Too much power, and not enough control."

Leo spun, bringing the blade around in a horizontal cut.

She ducked under it, stepping inside his guard and tapping his ribs with the flat of her blade. " Too wide and simple of an attack, any one can see it coming a mile away"

Frustration flared. Leo activated Defiance’s weight manipulation, making the blade heavier, and brought it down in a crushing overhead strike.

Iori caught it on her katana, and didn’t budge.

Leo’s eyes widened. She was using barely any aura, yet his full-force strike hadn’t moved her an inch.

"Efficiency," Iori said calmly, holding his blade in place with one hand. "You’re using ten times the energy I am right now, and I’m still stopping you. That’s the difference between us."

She pushed his blade aside and swept his legs out from under him in one fluid motion.

Leo hit the deck hard, breath knocked out of him.

Iori stood over him, sheathing her katana. "You fight like you’re always about to die, that worked in the forest, It won’t work forever, especially not against competent fighters."

Leo coughed, pushing himself up. "So what do I do differently?"

"Don’t just attack, think," Iori said, offering him a hand. "You’re not in survival mode anymore. Well you have time to learn, make sure to use it fully."

Leo took her hand, and she pulled him to his feet with surprising gentleness.

"We’ll train every day," she said. "Mornings and evenings, when I’m not handling delegation business. I’ll teach you control, precision, and how to build your own style. But you’ll need a proper master eventually, someone who can take you beyond the basics."

"Sounds like a lot of work," Leo said, catching his breath.

"It will be." Iori’s expression softened slightly. "But you’ve earned it, It’d be a waste to let that potential rot."

"Thanks," Leo said, meaning it.

"Don’t thank me yet." Iori turned back toward the bow. "We’ve got two weeks. By the time we reach the capital, you’ll at least know what you’re doing. Maybe."

Leo smiled despite the ache in his ribs. "I’ll take ’maybe.’"

They trained for another hour. Iori correcting his stance, his grip, the way he channeled aura through his limbs. It was exhausting in a different way than the hunt had been, this required focus, precision, constant adjustment, and adaptation wasn’t helping which confused Leo but he shock it off, it was axiom’s doing.

By the time she called a break, Leo’s shirt was soaked with sweat.

"Not bad," Iori said, leaning against the mast. "You’re a fast learner."

"High praise," Leo muttered, collapsing onto a nearby crate.

"It is, actually." She glanced at him, amusement flickering in her eyes. "Most people I’ve sparred with would be crying by now."

"Give me time."

She laughed, a genuine sound that caught him off guard.

"I like that you don’t give up easily, makes this more interesting."

"Glad I can entertain you."

"Oh, you do," Iori said, her tone playful. "Watching you flail around like a drowning cat has its charm."

Leo shot her a look. "I wasn’t that bad."

"You absolutely were." She pushed off the mast. "But you will improve , and that’s what matters."

Leo stood, wiping sweat from his face. "Same time tomorrow?"

"And tonight," Iori said. "After dinner. We’ll work on aura circulation while you rest. It’s less physical, but just as important."

"You’re serious about this."

"I don’t do things halfway," Iori said, meeting his eyes. "If I’m training you, I’m doing it right."

Something in her gaze made Leo’s chest tighten. "I won’t make you regret it."

"See that you don’t." She turned and headed toward the cabin entrance. "Go clean up. You smell like a wet dog."

Leo grinned. "You’re not as intimidating as you think, you know."

Iori paused at the doorway, glancing back over her shoulder. "And you’re not as charming as you think, but maybe you’ll get there."

She disappeared below deck before he could respond.

Leo stood there for a moment, replaying the morning in his head.

"Maybe axiom was right"

He shook his head, smiling to himself, and headed below deck to clean up.

Later that evening, Leo passed through the lower deck on his way back to his quarters.

A group of crew members worked near the cargo hold, reinforcing crates with heavy rope and additional strapping. Their movements were deliberate, practiced, like they’d done this before.

One of them muttered something Leo couldn’t quite catch.

"...when we hit the zone..."

Another replied, voice low. "...just like last time, captain says be ready."

Leo slowed, curiosity prickling at the back of his mind. The zone?

He was about to step closer when a voice called from behind.

"Leo."

He turned. One of Iori’s guards stood at the base of the stairs, expression neutral.

"Lady Iori requests your presence topside," the guard said. "She wishes to continue training."

Leo glanced back at the crew. They’d stopped talking, resuming their work in silence.

"Right," Leo said. "I’ll head up now."

He filed the overheard conversation away, something to ask about later, and followed the guard back up to the deck.

That night, after another grueling session, Leo sat across from Iori near the stern. The sun had set, and stars filled the sky overhead.

She’d spent the past hour teaching him aura circulation, how to cycle energy through his body without burning it off wastefully. It was tedious, meditative work, but he could already feel the difference.

"You’re doing better," Iori said, watching him. "Your flow is smoother than this morning."

"Doesn’t feel much different" Leo muttered, eyes closed as he focused.

"It never does at first." She leaned back, stretching her arms overhead. "But you’ll get there."

Leo opened his eyes. "And after that?"

"After that, you find a master," Iori said. "Someone who can push you past what I can teach."

"Any recommendations?"

"Depends on your path," she said thoughtfully. "If you want to focus on weapons and close combat, there are schools in the capital. If you want raw power and aura manipulation, the academies might suit you better."

"What do you think I should focus on?"

Iori studied him for a long moment. "I think you should figure out what kind of fighter you want to be. You’ve got the raw talent. The adaptability, but you’re still fighting like you’re trying to survive, that needs to change."

"Into what?"

"Into someone who fights because he’s strong," Iori said. "Not because he’s desperate."

Leo let that settle. She was right. Everything he’d done so far had been reactive, survival, adaptation, responding to threats. He hadn’t chosen his path yet.

"I’ll figure it out," he said finally.

"Good." Iori stood, brushing off her pants. "Get some rest. Tomorrow we’ll work on footwork, If you’re going to dual-wield those ridiculous swords, you need to move better."

"They’re not ridiculous."

"They’re three times wider than a normal blade," Iori said, smirking. "That’s ridiculous." 𝒻𝘳ℯℯ𝑤ℯ𝒷𝘯ℴ𝓋ℯ𝘭.𝑐ℴ𝑚

"They’re effective," Leo countered.

"We’ll see." She headed toward the cabin, then paused. "Leo."

"Yeah?"

"You did well today." Her voice was softer now, genuine. "Keep it up."

Before he could respond, she disappeared below deck.

Leo sat there, staring at the stars, feeling the quiet satisfaction of progress settle into his bones.

Two weeks.

He could do a lot in two weeks.
