The Heart of Zero

The man's gaze was icy and resolute, exuding a deadly aura that felt like an abyss devouring everything. Slowly, he extended his hands, and the black currents swirling around him condensed into a pair of pitch-black wings behind him. With a slight tremor, they emitted an overwhelming pressure.

Yahageshii and Shingin felt a chill seep into their very bones, but the battle intent within them only burned fiercer. Wiping the blood from the corner of his mouth, Yahageshii's eyes flared with a blazing fury. He roared, "Don't think you're invincible. Today, we'll show you what we so-called 'foolish youths' are capable of!"

Ryuosho rolled his shoulders lazily, the blue-yellow arcs of lightning dancing around his arms like restless thunder. A relaxed grin appeared on his face. "First time for everything. If we've come this far, I might as well join the fun."

On the rooftop, the three stood apart in a triangular formation, their gazes meeting briefly. Without words, a profound understanding formed between them, solidifying in this moment of life and death.

The man smirked coldly, his wings suddenly spreading wide. Black energy surged like a storm, sweeping across the rooftop with a force that seemed intent on tearing everything apart. Yahageshii charged first, his fists igniting with fierce flames that bathed the rooftop in red light. With a mighty punch, he struck at the man's chest!

The man scoffed, effortlessly deflecting Yahageshii's attack with a flick of his wing. He countered with a swift punch, striking Yahageshii squarely in the chest. Yahageshii was caught off guard, sent flying backward until he crashed into the railing, the impact shaking the structure as if it would collapse.

"Hmph. Such feeble power is nothing to me," the man sneered, his voice cold and merciless.

Furious, Shingin stepped forward, summoning his alien soul. Azure streams of water surged forth, forming whirlpools that lashed out with immense force, attempting to ensnare the man. Yet the man merely sneered, his wings unfurling again. The black energy shredded through the water torrents like blades, forcing Shingin to retreat several paces.

It was then that Ryuosho moved. His eyes sharpened, and the lightning within him surged to its peak. Blue-yellow electricity coursed over his body, forming a crackling armor of light. He dashed toward the man, his figure transforming into a streak of lightning, leaving behind a trail of azure afterimages in the air.

"Try this!" Ryuosho's electrified punch struck out with ferocious power. The sheer intensity of the energy ripped the air apart even before his fist connected. The man's expression shifted slightly as he raised his arms to block. Yet Ryuosho's lightning pierced his defense, leaving a scorched wound on his arm.

A flicker of shock crossed the man's face before it turned to anger. "You truly have no idea who you're facing!" he bellowed. With a furious sweep of his wings, he unleashed a powerful shockwave that forced Ryuosho back several steps.

Struggling to his feet, Yahageshii called out hoarsely, "Lazy slug! His defenses are tight. Let's take him down together!"

Shingin nodded, and the three launched their attacks in unison. Yahageshii's flames, Shingin's torrents, and Ryuosho's lightning intertwined, converging into a massive surge of energy aimed directly at the man.

The man's expression remained cold. With a sweep of his wings, he summoned a vortex of black energy to counter the combined assault. The resulting collision fractured the rooftop beneath their feet, and the structure groaned under the immense force.

Suddenly, Ryuosho felt a shift within him. The lightning in his veins seemed to reach a critical threshold, as if he were merging with the very storm above. Azure and yellow currents coiled around him, roaring like a dragon awakening within his soul. Raising his hand toward the darkened sky, he silently willed an unseen force.

In response, the clouds above churned and swirled, devouring the last traces of light. The oppressive darkness coalesced into a single terrifying mass, lightning dancing wildly within. A massive dragon of electricity, its azure and yellow scales crackling with power, writhed within the storm, roaring as though ready to descend upon the world.

A deafening crack of thunder split the air. From the storm's heart, a bolt of lightning tore through the heavens, descending with cataclysmic force. The blue-yellow lightning, a judgment from the skies, hurtled toward the man like divine retribution.

"BOOM!"

The lightning struck with an earth-shattering impact, its brilliance outshining the night. The rooftop trembled violently, the building quaking under the devastating force. Debris and rubble were flung into the air, raining down as the shockwave obliterated everything in its path.

Walls cracked, steel beams twisted, and the very foundation of the structure began to collapse. The lightning surged through the air, illuminating the entire campus in a blinding light that left onlookers below frozen in fear. Students on the field gazed upward, horrified by the apocalyptic scene unfolding on the rooftop.

When the light finally faded, smoke and ash hung heavy in the air. Amidst the rubble, the man still stood. His body was battered, his arm charred and smoking, his skin scorched and cracked. Yet, even in his battered state, a cold, unyielding fury burned in his eyes—a wrath that seemed to rise from the depths of hell itself.

Ryuosho's gaze narrowed as he gritted his teeth. "This guy... he's tougher than we thought."

Yahageshii and Shingin exchanged grim looks, their battle intent undiminished. In the brief silence, their resolve only grew stronger, each preparing for the next desperate assault.
