Smoke clung to the back of Mikasa's throat like wet wool. Ash drifted down from the shattered battlements of Fort Vesta, coating her dark hair and the cold steel of her twin blades. Screams echoed through the burning courtyard, but she registered them only as background noise. Steel clashed against steel a few yards away as her Jaeger Hunters engaged the remaining Eldian vanguard. Rain began to fall, but it did not cool the heat radiating from the burning wooden towers. It only turned the ash on the ground into a slippery, grey paste that coated her boots. She shifted her weight, balancing on the balls of her feet, her eyes locked on the next wave of attackers. Sweeping her blades in a low, lethal arc, she stepped forward to meet them. This was not a battle for territory; it was a slaughter. The Eldian forces had breached the outer wall at midnight, using their strange, devastating tactics to bypass the heavy iron gates. Now, the courtyard was a graveyard of broken stone and shattered lives. Shouts of panic rose from the Eldians as they saw her approach. They knew her face. They knew the crimson scarf tucked tightly beneath her leather collar. They knew the captain who commanded the elite hunters. Crouching low, she dodged a wild swing from a broadsword. Her left blade sliced through the attacker's tendons, sending him to his knees with a choked cry. Her right blade finished the job before he could hit the stone, a swift, merciless strike that required no thought. Two more soldiers rushed her, their spears leveled at her chest. Crimson sprayed across the gray stones as she spun between them. Her movements were a blur of pure, instinctual violence, a dance she had rehearsed a thousand times in her nightmares. She did not feel anger, not yet. She felt only the cold, hollow emptiness that had occupied her chest since the day her home was destroyed. Silence fell over the immediate area, broken only by the crackle of the flames. Looking down, she wiped her blade on the sleeve of a fallen enemy. Her knuckles were white where she gripped the hilts, her breathing shallow but controlled. She could feel the heavy thud of her pulse in her ears, a steady, relentless drumbeat that kept her moving. Crimson banners bearing the golden crest of the Eldian Empire fluttered from the battlements. Underneath the central banner stood the enemy standard bearer, desperately trying to rally the retreating remnants of the vanguard. He was shouting orders, his voice cracking with fear and exhaustion. Mikasa approached him slowly, her boots clicking against the wet stone. Something about the way he held himself made her pause. He was not a seasoned imperial soldier; his shoulders were hunched, his stance wide and defensive, like a boy pretending to be a man. Golden hair escaped from beneath his dented helmet as he turned to face her. Cold sweat broke out on Mikasa's forehead. Her breath caught in her throat, the icy fortress of her resolve cracking down the center. Memories rushed back, vivid and unwanted. She saw a sunny afternoon in the northern provinces, before the war, before the fire. She saw this same boy laughing as they shared a loaf of black bread beneath the shade of an old oak tree. Thomas. It was Thomas, her former comrade from the training academy, a boy who had sworn the same oath she had. "Mikasa?" he whispered, his eyes widening in recognition. His hand shook, the golden standard trembling in his grasp. "Please," he muttered, taking a step back. "You... you survived the purge." Gritting her teeth, Mikasa felt the grief in her chest twist, morphing into a colder, sharper resolve. This was what the Eldian Emperor did. Eren Jaeger took the people she loved and turned them into monsters, into enemies she had to destroy to survive. He had forced this boy to carry his banner of conquest. He had forced her to hold the blade that would end his life. Thomas lunged, a desperate, clumsy thrust of his spear. Her instincts, cold and unyielding, took over. She parried the spear, the impact vibrating up her arms. Her second blade found its mark, sinking deep between the plates of his armor. He gasped, his eyes locking onto hers with a mixture of shock and betrayal. Slowly, the golden standard slipped from his fingers, clattering into the mud. He fell forward, his weight dragging her blade down. Mikasa stood over him, her chest heaving, the rain washing the warm blood from her face. Her heart felt like a block of ice. The grief was gone, replaced by an unquenchable, burning fire of vengeance against the man who had orchestrated this tragedy. Emperor Eren Jaeger. He was the disease. She would be the cure. Standing amidst the ruins of Fort Vesta, she swore a new, silent oath. She would not stop until his empire was ashes. She would not rest until her blade found his throat. Wind howled through the ruined towers, carrying the scent of salt from the distant harbor. Suddenly, the ground beneath her feet began to tremble. It was not a tremor of the earth, but a vibration that seemed to shake the very air. As Mikasa stands victorious but alone, a distant, earth-shaking roar echoes across the scarred landscape, a sound she knows instantly belongs to Emperor Eren Jaeger, promising a storm far more devastating than any she has faced.
