The ground beneath Yuki softened.
His feet sank. Ankle-deep in an instant — the sand of the arena floor liquefying into thick, clinging mud. He dropped to knee-depth before he registered what had happened. The mud gripped him, dense and heavy, resisting movement.
Quagmire spell. She turned the ground into a trap.
He could break free easily. A burst of force magic or spatial displacement would rip him out in a fraction of a second. But he held back. This was interesting. He wanted to see what she'd do with the advantage.
What she did was cast lightning.
A bolt of condensed electrical mana leapt from her staff crystal and crossed the stage in an instant. Bright, crackling, powerful — easily the strongest single spell he'd seen from any mage in this world.
He threw up a barrier. Skin-tight, invisible — a shell of force wrapped so close to his body that from the outside, it looked like the lightning hit him directly. The bolt struck, discharged across the barrier's surface, and dissipated. Smoke rose from the sand around him.
In the stands, three people jumped to their feet.
Kana screamed. Hana grabbed Lira's arm. Lira was already half over the railing, bow in hand, face white.
The smoke cleared.
Yuki was floating. Cross-legged. Hovering a metre above the quagmire, completely untouched. His arms were folded. His expression was thoughtful.
"Wow," he said. "That was amazing."
The mage stared.
"A quagmire spell — I never thought of using earth magic defensively like that. You can subdue entire groups without killing them. That's brilliant." He was genuinely excited. "And the lightning — the mana compression on that bolt was incredible. The way you pulled atmospheric charge and combined it with your own output—"
"Are you... analyzing my spells? Mid-fight?"
"Force of habit. Sorry."
He cast the quagmire spell back at them.
The swordsman — mid-engagement with the daggers, focused entirely on the thirteen ironwood blades trying to hit him — sank to his hips without warning. The sudden stop killed his momentum. The daggers he'd been deflecting found openings. Three hit simultaneously — blunt impacts to the shoulder, ribs, and thigh. He grunted. Took more hits. Went down to his waist in mud, arms still defending, but losing ground fast.
The mage sank too — but she was ready. She seized control of the earth around her and launched herself upward on a pillar of compressed stone. Airborne, she shifted to wind magic — rapid-fire blades of compressed air, launched in a barrage at Yuki's hovering position.
Yuki cast his circular barrier — a sphere of force that he'd developed at the homestead, tested against his own full-power attacks. The wind blades hit it and shattered. Every single one.
He floated inside his barrier, still sitting cross-legged, perfectly calm.
"What else do you have to show me?"
The mage's eyes narrowed. The wicked smile returned — sharper now. Hungrier.
She began to chant.
Yuki watched with mana-enhanced vision as something massive took shape. Mana poured out of her — not a stream but a flood. Every Val she had, dumped into a single spell. The energy coalesced above her, pulling atmospheric mana into the vortex, combining her output with the ambient charge in the air. The pool of concentrated energy shot skyward.
Clouds gathered. The clear sky darkened. Wind picked up, swirling around the arena, whipping sand and dust into spirals.
The crowd murmured. Some stood. Some stepped back.
A column of light formed inside the cloud bank. Blue-white. Blinding. The charge built until the air itself tasted metallic.
Then the lightning came down.
Not a bolt — a pillar. A column of electrical force so massive it turned the arena blue-white. It descended directly toward Yuki with the inevitability of a falling mountain.
Oh.
For the first time since the dragon, Yuki felt fear.
Not rational fear — not I'm going to die fear. The primal, lizard-brain kind. The kind any human felt when they saw a lightning bolt coming straight at their face and their only defence was a magical barrier they'd built themselves.
Trust the barrier. Trust the work.
His mental enhancement was still active. The lightning crawled downward in slow motion — a branching tree of plasma, beautiful and terrible, reaching for him with fingers of pure energy.
He had minutes of subjective time. He used them.
I can block this. My barrier will hold. But that's a waste.
What if I captured it instead?
The idea formed fully in the time it took the lightning to descend a metre. He'd absorbed mana from kills. He'd stored energy in stones. Lightning was energy — electrical mana, raw and wild but fundamentally the same substance he worked with every day.
Infuse my mana into the lightning. Take control of it. Make it mine.
He extended his mana outward — not a barrier, not a shield. A net. A web of his own energy, woven into the descending lightning's path. When the bolt reached the web, his mana merged with it. Infused it. Claimed it.
The lightning resisted. Wild energy, chaotic, fighting his control. He pushed harder. Five parallel minds dedicated to the task, each one managing a section of the captured bolt.
The lightning stopped.
The entire column of electrical force — enough energy to level a building — hung frozen in the air above the arena. Crackling. Pulsing. Contained in a lattice of Yuki's mana.
The crowd went silent.
Yuki compressed it. The column shrank — from a pillar to a beam to a sphere to a point. He pulled it inward, crushing the energy denser and denser, until he held a ball of pure lightning the size of an apple. It crackled in his palm, white-hot, barely contained.
He pulled a blue mana stone from storage with his free hand. The same conductor he used for all his enchantments. He pressed the lightning sphere into the stone.
The stone absorbed it. The blue surface blazed white — filled to capacity with compressed electrical energy, pulsing like a heartbeat. A lightning battery. A weapon, a power source, a proof of concept.
Yuki held the stone up. Turned it over. The possibilities unfolded in his mind faster than he could catalogue them — lightning-infused weapons, electrical enchantments, storm-capture arrays —
"If I mounted a grid of these on a tower," he muttered, "I could capture every lightning strike in a thunderstorm. Store them. Deploy them later. A renewable energy weapon system—"
He was talking to himself. In the middle of a duel. While holding a captured lightning bolt.
He looked up. Remembered where he was.
The Platinum mage was on her knees. Swaying. Her mana was gone — completely spent on the lightning spell. Her face was grey with exhaustion, her staff the only thing keeping her upright. Her eyes, though — her light blue eyes were wide open, staring at the white stone in his hand with an expression that was equal parts horror and fascination.
The swordsman was unconscious. Waist-deep in the quagmire, slumped forward, ironwood daggers scattered around him. The relentless barrage had overwhelmed him once the mud took his mobility.
The arena was silent.
Yuki floated down to the stage. Landed. Dissolved the quagmire, letting the swordsman's body settle onto solid ground. Walked over to him and cast healing magic — bruises, minor fractures, exhaustion. Nothing life-threatening. The ironwood daggers hadn't been sharp enough to do serious damage.
He walked to the mage. She was still conscious — barely. He offered his hand.
She looked at it. Looked at him. Took it.
He pulled her up. Steadied her when she swayed. Cast a mild restoration spell — not full healing, just enough to take the edge off the mana depletion.
"That lightning spell," he said. "Seriously. That was the most impressive thing I've seen in this world."
She stared at him. The woman who hadn't been outclassed by anyone in a decade, who'd walked onto this stage expecting a challenging spar, was looking at a seventeen-year-old boy who'd captured her strongest attack with his bare hands and gotten excited about the engineering applications.
"Who are you?" she whispered.
"Just an adventurer."
She laughed. Weak, exhausted, but genuine. "No. You're not."
The arena stayed silent as Yuki walked back to the stands. The daggers returned to storage. The white lightning stone went into his pocket.
He climbed the steps to where Lira, Kana, and Hana were waiting.
Kana tackled his legs. "THAT WAS SO COOL."
Hana grabbed his hand and held it tight. Her ears were still flat from the lightning scare.
Lira stood in front of him. Her face was complicated — relief, pride, exasperation, and something deeper underneath.
"You said you'd be subtle," she said.
"I was subtle about some things."
"You captured a lightning bolt and started muttering about renewable energy."
"...that part was less subtle."
She shook her head. But she took his arm. And she didn't let go.
In the gazebo, the king sat very still. The guard captain beside him was pale. Wayne had found a chair and was using it.
Nobody in that gazebo had ever seen anything like what had just happened on that stage. Nobody in the Confederation had. Nobody in recorded history had.
The boy was already walking away, fox children hanging from his arms, a merchant's daughter at his side, talking about what to cook for dinner.
The king looked at his guard captain. The guard captain looked back.
Neither of them said a word. There was nothing to say.
The most powerful person on the continent had just moved into their city, and he was seventeen years old and more interested in lightning batteries than politics.
They were going to have to figure out what to do about that.
