The atmosphere inside the exam arena buzzed with anticipation. Students crowded the balconies above, their voices merging into a low roar of excitement. Dean Freaderick stepped down from the platform, his boots echoing sharply against the polished floor.

  Dean Freaderick: “All right, time to begin. The first match of the Midterms—Aaron Nanazawa versus Randall Crowe!”

  A hush rolled through the hall, tension instantly thickening.

  Aaron: “Looks like I’m up first.” He smiled faintly, rubbing the back of his neck. “Wish me luck, guys. Randall’s no pushover.”

  Emma: “Be careful, Aaron.”

  Hiruzen: “Yeah man, give it everything you’ve got.”

  Caitlyn: “You better not lose.”

  Aaron: laughing softly “Heh, thanks for the confidence.”

  Aaron and Randall stepped onto the arena floor. The lights above dimmed slightly as a small hovering robot descended, its black-and-white striped casing gleaming under the spotlights.

  RefBot: “Greetings. I am RefBot—official referee for all Midterm matches today. This bout ends when one combatant is unable to continue. No lethal strikes or unsanctioned attacks. Understood?”

  Randall: snorting “Yeah, yeah, we get it. Start the match already.”

  RefBot: “Acknowledged. Round One—Begin!”

  Randall cracked his neck and gestured lazily. “Since I don’t know much about your power, I’ll give you the first move.”

  Aaron exhaled calmly, eyes narrowing.

  Aaron: “My ability’s called Delta. It lets me measure, manipulate, and exploit the difference between two states of existence.”

  His right hand began to glow—soft, pale blue light spreading outward like circuitry. Faint numeric glyphs floated in the air around him.

  Aaron: “Light intensity, sixty-seven lumens… shadow density, forty-three percent. Delta constant between surfaces—twenty-four percent variable margin.” His lips curved faintly. “Perfect range for spatial compression.”

  He vanished.

  The floor buckled under a sudden force. To the crowd, it looked like teleportation—but Randall’s instincts screamed otherwise. Aaron reappeared right in front of him, fist wreathed in blue energy.

  The punch wasn’t fast by normal standards—yet Randall couldn’t react. The difference between their speeds had been nullified, made equal.

  Randall barely managed to block before sliding backward. “You’re not fast… you’re cheating distance!”

  Aaron: “Not cheating. Just equalizing the equation.”

  Randall chuckled darkly. “Then let’s see how you equalize this.”

  He raised both hands. Shadows erupted across the floor, twisting into wolves, serpents, and swords of darkness. They lunged from every direction, their movements jagged and chaotic.

  Aaron’s pupils shimmered with light-blue sigils, numbers spiraling rapidly.

  Aaron (thinking): Too many vectors. Each construct has its own motion—can’t nullify them all at once.

  A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.

  He pressed a hand to the ground. The energy rippled out in concentric rings.

  The weaker shadows flickered and collapsed instantly, their density destabilized by his adjustments. But three remained—thicker, reinforced by the energy of the others’ destruction.

  One lunged from behind. Aaron’s calculations shifted in an instant. He snapped his fingers.

  Aaron: “Delta Space Collapse.”

  The distance between him and the shadow doubled in an instant. The beast crashed into nothingness, as though it had stepped through an erased frame of reality.

  The remaining two closed in, their jaws wide. Aaron altered the delta between light and darkness around him—creating a bubble of illumination.

  The shadows entered it and dissolved like ink under a sunbeam.

  Randall scowled. “You and that freaky math trick of yours…” His grin returned, sharp and cold. “Fine. Time to show you what real darkness looks like.”

  He slammed his palms into the floor. Every shadow within fifty meters exploded outward, then expanded like liquid smoke, swallowing the arena whole.

  The lights vanished. The world went black.

  Aaron: “What… is this?”

  Randall: “This is my ultimate technique—Umbra Abyss. In here, there’s no light. No reference. No difference. Tell me—what’s your power worth now?”

  Aaron felt his heart spike. His entire power relied on two measurable states. Here, the delta between light and dark was zero– total equilibrium, infinite blindness.

  Aaron (thinking): No visual,no contrast,no calculable vector… so i must create one myself.

  He clenched his fist as equations spun around him in three dimensions.

  Aaron: “Delta Force amplifies the difference between my strength and yours!”

  A wave of blue light burst from his core, tearing fissures in the darkness. For a heartbeat, the void blinked—Randall’s constructs briefly visible as hollow silhouettes.

  Aaron moved again—his acceleration now balanced perfectly with Randall’s reaction time. Every strike was unreadable. Every dodge seamless.

  Randall’s shadows attacked in desperation, spearing through afterimages. Aaron slipped past each blow like liquid math, his steps precise to the decimal.

  He appeared at Randall’s side, hand glowing brighter than ever.

  Aaron: “Equation resolved.”

  His palm struck Randall’s chest—reversing the delta within his shadows.

  The darkness imploded inward, devouring its own mass. Randall screamed as cracks of black light split across his body.

  But even through the pain, he laughed. “You think this is over? Let’s end it with a singularity!”

  Randall spread his arms. His power spiked, warping the entire arena. Shadows began to converge– not outward, but inward,folding reality around them. The shadows formed a black hole like a vortex,dragging everything towards its center.

  Aaron’s equations flickered– his mental formulas crumbling under the gravitational chaos. His mind bled from the effort.

  Aaron(thinking): He’s creating an infinite delta between light and dark – collapsing reality itself. If he succeeds this entire arena will vanish.

  He closed his eyes.

  Aaron: Then I’ll collapse it first.

  His power ignited – forming a glowing blue triangle across his chest. The symbol of Delta burned brighter than the moon.

  Aaron: Ultimate Technique: Absolute Delta Collapse!

  In a single motion he designated two targets: Himself and Randall.

  Aaron: Collapse to zero

  The difference between them vanished. All motion,power,and energy balanced – every variable forcibly equalized. Randall’s vortex froze midspin. The shadows disintegrated into harmless mist. Aaron stood tall as Randall laid in silence. Then Randall coughed up blood and got up before falling to one knee.

  When the light returned, Aaron stood tall amid the fading glow. Randall knelt before him, breathing heavily, then coughed up blood and let out a raspy laugh.

  Randall: “Heh… guess I lost, huh?”

  Aaron: “Yeah. But you put up one hell of a fight.”

  Randall: “Yeah, yeah… RefBot, go ahead and make it official.”

  RefBot: “Winner of Round One—Aaron Nanazawa!”

  The crowd erupted. Aaron exhaled slowly, his blue aura fading into nothing.

  End Chapter.
