The battlefield had fallen silent.
Only moments ago, the training grounds had been consumed by a storm of radiant energy. Hundreds of concentrated beams had descended from the sky under Professor Hexio's command, tearing through the earth and forcing Ryusei Ryugu to the absolute limit of his endurance.
Now, all that remained was the aftermath.
Faint fragments of light still lingered in the air, drifting slowly across the battlefield like shimmering particles of stardust left behind by a violent storm. Some disappeared almost immediately, while others floated gently through the sunlight before fading into nothing.
The ground was scorched and cracked.
Deep craters covered the field.
Smoke rose from several impact points, twisting lazily into the morning air.
The smell of burned earth lingered around them.
And at the center of the devastation stood Ryusei.
Barely.
His entire body trembled.
His legs felt as though they could give out at any moment, and his arms hung heavily at his sides. Burn marks stretched across his exposed skin, while his clothes had been torn in several places by the relentless barrage.
Blood trickled from a small cut near his forehead.
Sweat ran down his face and disappeared beneath his jaw.
His breathing was ragged.
Every inhale was sharp.
Every exhale was painful.
It felt as though each breath scraped against his lungs.
Yet despite all of that—
Ryusei was still standing.
His feet remained planted against the ruined ground.
Across from him, Professor Hexio slowly lowered his hand.
The brilliant aura that had surrounded his body gradually disappeared. The hundreds of weapons of light suspended in the sky vanished one after another until not even a single beam remained.
The overwhelming pressure that had filled the battlefield disappeared with them.
What remained was simply Professor Hexio.
Calm.
Composed.
Almost completely untouched.
His coat fluttered gently in the breeze.
His glasses caught the sunlight as he looked toward Ryusei.
His expression remained neutral.
But his eyes were different.
Sharp.
Observant.
Evaluating every detail of the boy standing before him.
"...You're still conscious."
Hexio's voice was quiet.
It wasn't praise.
It was an observation.
An evaluation of Ryusei's condition.
Ryusei tried to answer.
His lips parted.
But no sound came out.
His throat felt dry.
His body suddenly lost what little strength remained.
His knees buckled.
"Ghh...!"
Ryusei dropped onto one knee, catching himself with one hand against the cracked earth.
Pain surged through his body.
His fingers dug into the dirt.
For a moment, his vision turned white.
The attack had not merely struck him.
It had overwhelmed him.
Every defense he attempted had been broken.
Every movement had been predicted.
Every escape route had been closed.
Professor Hexio's spell had been absolute.
Ryusei lowered his head and struggled to breathe.
From the edge of the field, Kayosha instinctively stepped forward.
"Ryusei—!"
She stopped herself before crossing the boundary.
Her hands clenched tightly against her chest.
Her expression was filled with worry.
She wanted to run to him.
She wanted to help him.
But she knew this wasn't her battle.
Ryusei had challenged Hexio himself.
He had chosen this.
And if he wanted to become stronger, there were some things he had to face on his own.
Kayosha slowly lowered her foot.
"...Come on, Ryusei."
Her voice was barely audible.
"Get back up."
Back in the center of the field, Ryusei forced himself to raise his head.
His vision remained blurry.
Hexio's figure seemed to sway slightly in front of him.
Ryusei blinked several times until the professor came back into focus.
Then he looked directly at him.
"...That attack..."
His voice was weak and hoarse.
He swallowed painfully.
"...How... did you do that...?"
Hexio didn't answer immediately.
Instead, he began walking toward him.
His footsteps echoed softly across the cracked earth.
Step.
Step.
Step.
Each step was slow and deliberate.
When Hexio finally stopped, he stood directly in front of Ryusei.
Ryusei looked up.
Hexio looked down.
For several seconds, neither spoke.
Then Hexio's eyes narrowed.
"You're asking the wrong question."
Ryusei's eyebrows drew together.
"...What?"
"The question isn't how I did it."
Hexio's voice remained calm.
But there was a firmness behind it now.
"The question is why you couldn't."
Ryusei's expression froze.
The words struck harder than he expected.
Hexio continued.
"You possess the same elemental attribute as I do."
He gestured slightly toward Ryusei's hand.
"Light."
Ryusei looked down.
A faint glow remained around his fingers.
It was barely visible.
Unstable.
Flickering in and out of existence.
Hexio's eyes returned to him.
"Yet the difference between us..."
He paused.
"...is the difference between a spark and the sun."
Ryusei's chest tightened.
Those words hurt.
Not because they were cruel.
Because they were true.
He lowered his gaze.
His fingers slowly curled into a fist.
"...I know that."
His voice trembled.
"I know I'm weak."
The memories came rushing back.
The frozen lake.
The ruined battlefield in the forest.
The people he had desperately tried to save.
The fear in their eyes.
The overwhelming presence of enemies he hadn't been prepared to face.
Nekuro.
The destruction.
The helplessness.
And then—
Ryushi's words.
You are the only hope left.
Ryusei's fist tightened.
His nails pressed into his palm.
He remembered standing there, knowing that people were depending on him while he barely understood his own abilities.
He remembered how powerless he had felt.
That feeling was something he never wanted to experience again.
Ryusei slowly raised his head.
His eyes were no longer filled with frustration.
Something stronger had taken its place.
Resolve.
"...That's why I'm here."
Hexio remained silent.
Ryusei pushed his trembling hand against the ground and slowly began to rise.
His legs shook violently beneath him.
But he refused to stop.
"I don't care how hard it is."
He pulled himself upright.
"I don't care how long it takes."
His breathing remained rough.
"I need to learn this power."
He looked directly at Hexio.
"I need to become stronger."
His voice became steadier with every word.
"So please..."
Ryusei lowered his head slightly.
"...Teach me."
The wind passed quietly through the battlefield.
It carried dust and small fragments of ash across the ruined ground.
For a moment, Professor Hexio said nothing.
His gaze remained fixed on Ryusei.
He wasn't looking at his injuries.
He wasn't examining his remaining magical power.
He wasn't judging the strength of his Elemental Art.
He was studying something deeper.
The boy's determination.
Finally, Hexio spoke.
"...You're reckless."
Ryusei flinched slightly.
"You rush into battles you're not prepared for."
Hexio's voice remained steady.
"You take on enemies far beyond your current level."
Another pause.
"You rely on instinct more than understanding."
Ryusei lowered his eyes.
Every criticism was accurate.
He couldn't deny any of it.
"And yet..."
Hexio's voice changed.
Only slightly.
"...you survived."
Ryusei looked up.
Confusion crossed his face.
Hexio turned his back toward him.
"Do you know how many Elementalists die because they hesitate?"
Ryusei didn't answer.
The professor looked toward the ruined training field.
"An Elementalist can possess extraordinary power and still die because they spend too long wondering whether they should use it."
His gaze moved across the craters.
"Fear can kill as easily as an enemy's spell."
He glanced over his shoulder.
"Power isn't simply about control."
His eyes met Ryusei's.
"It's about conviction."
Ryusei remained silent.
"And you have that."
From the sidelines, Kayosha's eyes widened slightly.
There was something different about Hexio's voice.
It wasn't quite warmth.
But it wasn't the cold evaluation from earlier either.
It was recognition.
Hexio turned back toward Ryusei.
"However..."
His expression became serious again.
"Conviction alone isn't enough."
Ryusei listened carefully.
"Without control, your conviction will eventually destroy you."
Ryusei looked down at his hands.
He understood.
He had already seen what happened when his power exceeded his control.
He had felt it himself.
The instability.
The loss of direction.
The overwhelming pressure.
His own power could become just as dangerous as any enemy.
Ryusei slowly pushed himself upright.
His body shook.
His knees nearly buckled again.
But he forced himself to remain standing.
"...Then teach me control."
Hexio watched him.
A long silence followed.
Then the professor's expression softened by the smallest amount.
"You challenged me to a duel."
Ryusei blinked.
Hexio continued.
"And you're still standing."
His eyes moved over Ryusei's battered body.
"Barely."
For the first time, a faint smile appeared at the corner of Hexio's mouth.
It was so subtle that Ryusei almost wondered if he had imagined it.
"Very well."
Ryusei stared at him.
"...What?"
Hexio straightened.
"You win."
Ryusei froze.
His brain struggled to process the words.
"...W-Wait."
He blinked.
"What?"
Hexio turned fully toward him.
"I'll train you."
Silence.
Ryusei simply stared.
The battlefield seemed to disappear around him.
The pain.
The exhaustion.
The ruined field.
For a moment, none of it mattered.
"...You mean it?"
Hexio nodded once.
"I don't accept disciples lightly."
His expression became serious.
"If you're going to walk the path of light..."
He paused.
"...then you will walk it properly."
Ryusei's eyes widened.
Something warm spread through his chest.
Not the overwhelming sensation of magical power.
Something different.
Hope.
Hexio slowly raised one hand.
A faint glow appeared around his fingertips.
This light was different from the attack he had used moments earlier.
It wasn't destructive.
It didn't carry pressure.
It didn't threaten to tear apart the battlefield.
It simply existed.
Steady.
Quiet.
Controlled.
The glow pulsed gently like a heartbeat.
Ryusei stared at it.
He couldn't look away.
Hexio noticed his expression.
"Your problem," he said, "is that you're forcing your power outward."
Ryusei listened.
"You treat your Elemental Art like a weapon."
The light moved between Hexio's fingers.
"But light isn't meant to be forced."
The glow shifted gently.
"It flows."
The light moved across his palm.
"It connects."
It gathered around his fingertips.
"It responds."
Ryusei's eyes followed every movement.
Hexio slowly closed his hand.
The light disappeared.
"Until you understand that..."
He looked directly into Ryusei's eyes.
"...you'll never reach your full potential."
Ryusei stood completely still.
He replayed Hexio's words inside his mind.
Light flows.
It connects.
It responds.
Until now, he had always thought of his power as something he had to command.
Something he needed to force into existence.
Something he had to turn into a weapon powerful enough to defeat whatever stood in his way.
But perhaps that was the problem.
Maybe light wasn't something he needed to dominate.
Maybe he needed to understand it.
Ryusei slowly looked down at his hand.
A tiny spark appeared between his fingers.
It flickered.
It almost disappeared.
Then returned.
Ryusei watched it carefully.
He didn't try to force it to become a blade.
He didn't try to increase its size.
He simply watched.
The glow remained for a few seconds before fading away.
Ryusei smiled faintly.
"...I understand."
He paused.
Then gave a tired laugh.
"Or at least..."
His eyes returned to Hexio.
"...I will."
For the first time, Hexio gave a small nod of approval.
"...Good."
That single word carried more weight than Ryusei expected.
Then—
"Ryusei!"
Kayosha rushed across the field.
She reached him before he could react and grabbed his arm, immediately supporting some of his weight.
Ryusei nearly stumbled.
"Whoa..."
Kayosha glared at him.
"You idiot!"
Her voice trembled.
"You pushed yourself way too far!"
Ryusei gave a weak laugh.
"...Yeah."
He looked down at himself.
His torn clothes.
The burns.
The dirt covering his arms.
"...I know."
Kayosha's expression remained worried.
"You could have seriously hurt yourself."
"I know."
"You could barely stand."
"I know."
"And you still kept fighting!"
Ryusei looked at her.
A faint smile appeared on his face.
"...Yeah."
Kayosha stared at him.
For a moment, she looked as though she wanted to scold him again.
Instead, she sighed.
Her shoulders relaxed.
At least he was safe.
At least he was still standing.
And now—
He had someone who could teach him.
Ryusei glanced past her.
Professor Hexio had already begun walking away from the battlefield.
Ryusei watched him for a moment.
Then looked at his own hand.
A faint glow appeared between his fingers.
This time, he didn't try to shape it.
He simply let it exist.
"...But it was worth it."
Kayosha looked at him.
"Worth it?"
Ryusei nodded.
"Yeah."
He looked toward Hexio.
"Because now I have a teacher."
Kayosha followed his gaze.
A small smile appeared on her face.
"...Then you'd better work hard."
Ryusei smiled.
"I will."
The sun had begun its descent toward the horizon.
Golden light stretched across the academy grounds, covering the ruined battlefield in a warm glow.
The same field that had been torn apart by Hexio's attack now looked almost peaceful.
The smoke was slowly disappearing.
The dust was settling.
The last fragments of magical light drifted away on the evening breeze.
For the first time since the duel began, there was no tension in the air.
Only silence.
And within that silence, something had changed.
Ryusei had entered the battlefield believing that he needed more power.
He had left it understanding that power alone meant nothing.
He needed control.
Understanding.
Discipline.
And most importantly—
A reason to wield the power he possessed.
Professor Hexio had opened a new path before him.
A path that would undoubtedly be difficult.
There would be failures.
There would be pain.
There would be moments when Ryusei would question whether he was capable of mastering the power inside him.
But he no longer had to walk that road alone.
Ryusei closed his hand.
The small light disappeared.
He looked toward the horizon.
His eyes were tired.
His body was exhausted.
But his expression was brighter than it had been that morning.
A new journey had begun.
And this time, Ryusei Ryugu would not simply seek greater power.
He would learn to become worthy of it.
The path of light had opened before him.
And this—
Was only the beginning.
