I Enslaved The Goddess Who Summoned Me

Despite her quiet nature, Akane had always been polite and respectful towards me, a silent understanding passing between us that hinted at a mutual fondness. I had cherished them both in my own way, but Akane\'s reserved demeanor made her feelings all the more profound, even if they were seldom expressed in words.

Time had not altered Akane\'s appearance much, yet there was an undeniable change in her aura. She had become even more unique, her presence colder and more distant, as if she had erected invisible walls around herself. It was as though she had become an unapproachable figure, her silence now carrying an edge of something darker and more formidable.

In a swift, fluid motion, she raised her black katana, the blade shimmering ominously with a dark, ethereal light. Without hesitation, she launched herself toward me, her speed a blur.

BADOOOM!

The ground trembled under the force of our clash as her katana collided with my own black sword. The impact reverberated through the air, sending shockwaves of darkness rippling outwards. I stood firm, my feet rooted to the spot, my sword held vertically to parry her strike. The force of her attack was immense, but I did not budge.

Akane, her feet anchored to the ground, gripped the hilt of her katana with both hands, every muscle in her body straining as she poured all her strength into the attack. The blade trembled against mine, a testament to the sheer power she was exerting. Her expression was one of fierce coldness, but there was something else in her eyes—something that tugged at a distant memory.

My gaze remained fixed on her face, the face I never thought I would see again. It was both familiar and foreign, a haunting reminder of a past that seemed so far away. The ground beneath us began to crack under the pressure of our combined forces, and Akane, with a surge of mana, intensified her assault. The air around us whipped into a frenzy, sending my black hair billowing wildly.

Out of the corner of my eye, I saw Yumiko struggling within the confines of the prison I had constructed around her. She was on her knees, her small frame huddled in a futile attempt to protect herself.

"Hyaaa!!!" Yumiko\'s cry of desperation echoed through the chaos, her voice laced with fear and helplessness.

"Y… Yumiko!! Damn it!! I can\'t break it!!" Ryuuki\'s voice was frantic as he relentlessly slashed at the prison with all his might, his desperation to save her evident in every swing of his blade.

For a brief moment, Akane\'s focus wavered. Her gaze flickered toward her classmate, the slightest hint of concern crossing her features. It was all the opening I needed. With a swift motion, I parried her katana to the side and delivered a powerful kick to her ribs.

Akane reacted quickly, bringing her arm up to shield herself from the blow, but the force of the impact was too great. She was sent flying, her body skidding across the ground before she managed to regain her footing.

"Sister!!" Ayaka\'s anguished voice cut through the tension, her eyes wide with fear as she looked at Akane\'s fallen form before turning her gaze to me, now filled with a mixture of anger and dread.

"A… Ayaka! I need your help, please!!" Ryuuki\'s plea was desperate as he continued to attack the black prison, his blade flashing in the dim light.

"R… Right!!" Ayaka, her anger barely suppressed, nodded in agreement. She could see the struggle in Ryuuki\'s eyes and knew that the situation was dire. With a determined expression, she raised her white katana, its blade gleaming with a pure, radiant light—the perfect counter to my dark magic.

"White Blade!" Ayaka\'s voice rang out as she thrust her katana forward, its tip aimed directly at the prison I had constructed. The blade pierced through the darkness, and cracks began to form along the surface, the white light seeping into the void like a healing balm.

A flicker of hope crossed Ryuuki\'s face, his lips curling into a small smile as he saw the prison beginning to break. But his hope was short-lived.

In an instant, my fist connected with his face, the force of the blow sending him crashing into the ground with a sickening thud. He skidded across the dirt, his momentum only stopping when he collided with his fallen comrades.

"R… Ryuuki!!" The horrified voices of Yumiko and Ayaka echoed through the clearing, their concern for their friend overriding their own fear.

"You bastard!" Ayaka\'s glare was venomous as she turned her attention to me, her white katana still glowing with a fierce light. But she hesitated, torn between the need to defend Yumiko and the desire to attack me.

I paid no heed to her frantic pleas and raised my sword, its ominous blade now poised above Yumiko.

"W...wait!!" Ayaka\'s voice trembled, her face paling as she realized the imminent danger.

"I... I won\'t let you!!"

Before I could bring the sword down, a powerful bolt of lightning crackled through the air, surging toward me with ferocious speed. Without breaking my gaze, I extended my left hand, absorbing the electric energy that erupted from Ryuuki\'s twin swords. The force of it coursed through me, but I remained unfazed, my expression cold.

Ryuuki was bleeding, his body battered from the relentless battle, yet his fierce gaze was locked onto mine. There was no mistaking the murderous intent in his eyes.

"Now you look like you want to kill me," I observed, my voice icy and devoid of emotion. "But it\'s not enough."

With deliberate slowness, I raised my sword again, the blade gleaming menacingly as it hovered above Yumiko.

"Stop that bastard!!!" Ryuuki roared, his voice carrying a raw edge of desperation. To my ears, his words sounded foreign, tinged with the familiar cadence of Japanese.

In an instant, he charged at me, his movements a blur as he closed the distance with remarkable speed. His swords flashed through the air, their deadly arcs aimed straight at me.

I met his attack head-on, blocking his strikes with my black sword. The sound of metal clashing against metal rang out as our blades collided. Ryuuki was relentless, his twin swords slashing at me with a wild, frenzied energy.

But there was a stark contrast between us. While his movements were erratic and fueled by raw emotion, mine were measured and calm. Each of my parries was precise, each counterstrike deliberate. It was clear that he was fighting with every ounce of strength he had left, but his lack of control made him predictable.

Amidst our intense duel, I felt a surge of black energy aimed at me from the side. It was Akane, her katana glowing with dark light as she rushed forward, thrusting her blade with deadly intent.

In a split second, I made a calculated move. I parried Ryuuki\'s swords above him, then swiftly grabbed his shirt, using his body as a shield against Akane\'s incoming attack.

"SHIELDS!!!" Kazuto\'s urgent voice rang out, and just in time, a protective barrier formed around Ryuuki, saving him from being skewered by Akane\'s katana.

"White Blade!" Ayaka\'s furious shout echoed from behind me. She had succeeded in freeing Yumiko from the black prison and now joined the fray, her white katana shimmering with pure, radiant light. She charged at me with vengeance in her eyes, her blade slashing through the air with deadly precision.

"DIE, YOU BASTARD!!!"

From above, I saw Yusuke descending, his entire body pulsating with mana. The air around him crackled with energy as he prepared to unleash a powerful spell.

"Celestial Rank Magic," he intoned, his voice resonating with the gravity of the spell he was about to cast.

BADAM!

I slammed Ryuuki\'s body into the ground, the impact shaking the earth beneath us. Placing my hand firmly on his abdomen, I knelt on one knee, drawing all of his remaining mana into myself.

"Black Tornado," I whispered, and immediately, a dark whirlwind began to swirl around us, growing in intensity with each passing second. The vortex of darkness expanded, a swirling mass of black energy that consumed everything in its path.

BADOOOOM!

The force of the tornado was overwhelming. Akane, Ayaka, and Yusuke were all caught in its fury, their bodies flung violently through the air. The sheer power of the black vortex sent everyone, even those at the periphery, hurtling toward the edges of the barrier erected by Medea.

The tornado raged for what felt like an eternity, its deafening roar drowning out all other sounds. When it finally subsided, a heavy silence fell over the battlefield, broken only by the groans of those who had been caught in the storm.

Dust and debris hung in the air, but with a wave of her hand, Medea cleared it away, revealing the aftermath of the devastation. Ryuuki\'s unconscious body lay crumpled on the ground, utterly spent and motionless.

"RYUUKIIIIII!!!" Yumiko\'s horrified scream pierced the silence, her voice raw with anguish as she rushed toward his fallen form. Her eyes blazed with fury as she glared at me, her grief quickly turning into murderous intent.

Without hesitation, she summoned her spear and charged at me, her movements fueled by a desperate need for revenge. But before she could even reach me, I was already there, standing directly in front of her.

Yumiko froze, her body seized by fear as she realized she was too slow to raise her weapon in time. My sword swung toward her head, aiming to end the fight in one swift strike.

But before the blade could connect, a white katana intercepted it, the force of the clash sending sparks flying.

Akane clenched her teeth, struggling against the overwhelming force of my strike. Despite her determination, the power behind my swing was too much for her to withstand. She was thrown backward, and in the process, she managed to grab hold of Yumiko, pulling her along as they both tumbled through the air.

"P…PROTECT THE HEROES!!!" a desperate voice rang out. It was a cry from one of the knights of Kastoria, who had been watching the battle unfold with mounting horror. Until now, they had hesitated to intervene, knowing they were no match for their own strongest warriors, let alone me. But seeing their heroes falter, they could no longer stand idly by.

The knights surged forward in a wave, their numbers reaching into the hundreds. They unleashed a barrage of magical attacks, a dazzling array of elements that lit up the battlefield with a cacophony of light and sound. Fire, ice, lightning—everything they could muster was hurled at me in a desperate bid to overwhelm.

I charged forward, a wall of darkness rising above me. The shadowy force absorbed their attacks as if they were nothing more than raindrops against a storm. The first knight who dared to close in on me swung his sword with all his might, but he was too slow. I easily sidestepped his strike and with a swift motion, sliced off his arm.

Blood sprayed from the wound as he screamed in agony, his severed limb falling to the ground.

What followed was nothing short of a massacre.

I cut through the ranks of knights with ruthless efficiency, my black sword carving through flesh and bone as though they were paper. Each swing of my blade ended a life, each step I took leaving behind a trail of carnage. The air was thick with the stench of blood, the ground beneath me growing slick with it. My dark armor and hair were soon drenched in crimson, but I paid it no mind.

I continued to kill, each life taken without hesitation or remorse, while the horrified eyes of the Heroes of Kastoria watched, powerless to stop the slaughter.

Yes. Watch closely.

This is the true face of this world.

After dispatching what must have been the hundredth knight, I suddenly felt a surge of danger and instinctively stepped back, narrowly avoiding a black flash that sliced through the space I had just occupied.

It was Akane again, but she was different now. Black veins pulsed along her body, and her strength had grown exponentially, at least five times stronger than before—and it seemed to be increasing by the second. Her aura was suffused with a dark energy that was both familiar and terrifying.

She took a stance, her movements sharp and precise, and in the blink of an eye, she vanished. Her speed was astounding, nearly beyond my ability to track. But my demonic left eye caught the faintest trace of her movement.

I swung my sword with all my might.

BADOOOM!

This time, the impact sent me sliding back several meters, the force of the collision reverberating through my entire body. Akane\'s eyes glowed faintly red, her expression a mixture of pain and rage. Yet despite the obvious strain, she rushed at me once more, her intent clear—she meant to kill.

I met her charge head-on, parrying her sword with my own, but the force of her blows was immense. Each strike made my arm throb with the effort of holding my ground, yet I remained outwardly calm, refusing to show any sign of weakness. We traded blows at a furious pace, her relentless assault gradually pushing me back.

All the while, I kept my gaze locked on hers, memories flashing through my mind in a chaotic blur. Memories of who she once was, and of the bond we once shared.

With a strong grip on my hilt, I braced myself and parried her next powerful swing. But this time, I did not give an inch. I held firm, my feet rooted to the ground as our swords clashed with a deafening clang.

Akane\'s hands trembled from the force of the impact. Her cold, calculating gaze bore into mine, our faces now mere inches apart. In that moment, something inside me stirred—an impulse, a need to say something that had long been left unspoken.

"You\'ve become strong, Akane," I said, my voice was as cold as before but there was an undeniable softness.

"!"

Akane froze, her fierce expression faltering. Her eyes widened in shock, the coldness draining from her face as she stared at me, as if seeing me for the first time. Her lips quivered, and she hesitated before speaking, her voice trembling with disbelief.

"O…Onii-sama…"
