A vast field stretched for five square kilometers, reaching all the way to the horizon.

  The sky, as if aware of the gravity of the moment, was veiled with thin clouds, through which a cold light seeped down.

  On one side stood Headmaster Selveran, his long cloak rippling slightly in the wind.

  On the other — Rosaline, sword in hand, and Hiro, standing a step behind her — calm, detached, as if watching a game unfold before him.

  A fiery sphere burst into the sky — the signal to begin.

  It exploded with a deep thunder, and the earth itself trembled beneath their feet.

  Rosaline was the first to move.

  Her steps were swift and light, like a gust of wind.

  The sword flashed in her hands as clouds of dust rose around her.

  Hiro didn’t move.

  He simply stood there, watching — eyes half-lidded, as if playing his own silent game.

  > “White makes the first move,” he murmured. “Then I’ll play as black.”

  The Headmaster made the first move.

  The air around him ignited.

  Pillars of earth erupted from the ground, forming barriers and walls, followed by a rain of fireballs that exploded above the field.

  Lightning cut through the sky, and sudden gusts of wind swept across the battlefield — moving diagonally, like pieces on a colossal chessboard.

  > “He’s placing rooks and knights,” Hiro observed calmly. “Classic defensive play.”

  He raised his hand.

  From the ground rose metallic pillars, stretching toward the heavens, connected by arcs of pure energy.

  > “Pawns,” he said.

  A faint vibration spread from each — a mana resonance linking the entire field.

  Then, around them, swirling fire vortexes appeared, circling like guardian spirits.

  > “Rooks. Your move, Headmaster.”

  Meanwhile, Rosaline darted through the grassy field, weaving between earthen walls and flashes of light.

  A bolt of lightning struck before her — but stopped a few meters short.

  A metallic pole had emerged from the soil, absorbing the impact completely.

  Rosaline froze, startled.

  > “What… was that?” she whispered.

  If you come across this story on Amazon, be aware that it has been stolen from Royal Road. Please report it.

  No answer came — only the hiss of scorched air and the faint scent of ozone.

  A stone wall suddenly burst upward before her. She lifted her sword to strike —

  —but the wall shattered in an instant, blasted apart by a bolt of pink lightning.

  Fragments of stone glimmered midair.

  Rosaline’s eyes widened. Someone had just saved her.

  > “…Hiro,” she whispered, gripping her sword tighter.

  He still stood far behind, eyes cold and focused.

  A faint line of light burned across his palm — the trace of his last spell.

  > “Don’t stop,” he said quietly — as if she could hear him from afar.

  And she understood.

  She no longer looked back.

  She ran — forward, the sword blazing, the air trembling around her.

  Selveran watched, intrigued.

  > “He doesn’t interfere… but still alters the flow. Interesting.”

  He raised his hand.

  The air quivered, and above him materialized dozens of elemental constructs — beings of stone, flame, and wind, each moving in deliberate formations.

  > “Check,” he said calmly, releasing his spell.

  Lightning stormed across the heavens. The earth cracked. The world itself seemed to tighten.

  Hiro smiled faintly.

  > “Just a check, Headmaster. You’re still far from mate.”

  He lowered his hand.

  The metallic pillars twisted, transforming into mirror-like spheres reflecting the storming sky.

  Each one captured a bolt of lightning, redirecting its energy toward the center — toward Rosaline’s path.

  Now, instead of striking the earth, lightning guided her — carving a road of light straight to the Headmaster.

  > “So,” Selveran said, narrowing his eyes, “you’ve chosen to play the hidden King behind your pawns.

  But remember, Hiro — I’m the one who sees the whole board.”

  The air rumbled. Cracks raced from his feet.

  The earth split apart, and sand lifted in a wild spiral.

  Hiro clenched his fist.

  One of his mirror spheres shattered into fragments of light, embedding into the ground and detonating — nullifying the shockwave.

  Selveran smiled faintly.

  > “Now I see why you fascinate me.”

  Rosaline was close now — her every step lighting the ground beneath her feet.

  The battlefield pulsed — a living chessboard of mana.

  ---

  The Field of Kings

  She dashed forward.

  Lightning crashed, the sky burned, and the world itself felt alive.

  Selveran looked up — and finally saw it.

  A colossal structure unfolded before him — a transparent emerald grid stretching across the land.

  Each square vibrated, overflowing with magic.

  Figures stood upon it in perfect formation.

  > “You… turned the entire field into a chessboard?” he whispered.

  He struck the ground, summoning four colossal stone walls that closed in on Rosaline from all directions.

  Hiro exhaled.

  Before him, a luminous chessboard appeared midair, glowing with pink energy.

  > “Four queens in one move? Breaking the rules, are we?” he smirked.

  “Fine. I can do that too.”

  He grasped the board by its edges — and stretched it.

  Space itself bent. Lines multiplied. A ninth rank appeared, both vertically and horizontally.

  The world shuddered.

  Selveran gasped.

  > “That’s… impossible.”

  Hiro placed a new piece — between the King and Queen’s squares.

  A figure appeared: a young man wearing a tilted crown, a chain in one hand, and a radiant sword in the other.

  > “The Prince is ready,” Hiro said softly.

  He moved the piece forward — directly above Rosaline’s cell.

  His sword ignited in pink flame, lightning coursing through his veins like living light.

  > “My move,” he said, and leapt.

  The world erupted.

  Hiro soared through the air, leaving a trail of rose-colored fire.

  He appeared above Rosaline in an instant —

  —and with one sweep of his arm, the walls surrounding her crumbled into dust.

  On the ethereal chessboard, Selveran’s four queens burst into light and vanished.

  The Headmaster froze — not in fear, but in revelation.

  He met Hiro’s eyes — and the world went silent.

  Magic drained from his body.

  His spells disintegrated into ash.

  Cold sweat trickled down his face.

  And then — he felt it.

  Cold steel against his throat.

  A whisper at his ear.

  > “Check,” Hiro said —

  his voice echoing inside Selveran’s mind.

  He couldn’t move. Couldn’t breathe.

  And in that suspended moment — Rosaline reached him.

  She leapt, her sword gleaming in the fading light,

  the blade stopping just at Selveran’s chest.

  The whisper came again — calm, final, inevitable.

  > “Mate.”

  The paralysis faded.

  Magic returned to Selveran’s limbs.

  He blinked — and saw Rosaline standing before him, sword lowered.

  A long silence followed.

  Then the Headmaster smiled faintly.

  > “I lost,” he said quietly.

  The wind carried away the dust.

  The board faded.

  The world exhaled.

  Rosaline lowered her sword.

  Hiro stood on a distant hill, a faint victorious smile on his lips.

  He walked toward them.

  > “That was… entertaining,” he said simply.

  In his hand still burned the rose-colored sword.

  Rosaline extended her arm.

  > “Give it back.”

  Hiro handed it over.

  But the moment she touched it, the sword crumbled to dust.

  > “What…?” she whispered.

  Hiro shrugged.

  > “The blade would’ve shattered from a single strike made by me. I held its form together with mana — but once I stopped maintaining

  it, it dissolved.

  Seems the steel just couldn’t handle that kind of power.”

  Rosaline looked at him, then at her hands still dusted with silver ash.

  After a moment, she brushed them off and sighed.

  > “You can’t be trusted with anything anymore.”
