Kyoraku Shunsui met Jūshirō's eyes. Between them flickered the same disbelief, a silent realization that both had been wrong. They once thought their Zanpakutō had escaped Muramasa's control, but the truth hit like a cruel strike neither could release their blades. Not even a spark of response.
Their faces darkened, and the weight of that silence pressed on the hill. All around, the Shinigami's expressions turned grim. If even the oldest captains of the Gotei 13 were denied their Zanpakutō, what hope remained for anyone else? Had every sword in Soul Society already betrayed its master?
The unease thickened until even breathing felt like wading through mist.
Among the crowd, Unohana Retsu stepped forward, her steps unhurried, her calm face shadowed with cold composure. "Our Zanpakutō have been stripped away by your ability," she said, voice soft but cutting through the air. "But I'm surprised… why isn't my sword beast among them? And judging from the scene, neither are those belonging to Jūshirō or Kyōraku."
Her eyes, narrowing slightly, glinted with an ominous calm.
Kyōraku and Ukitake's expressions grew heavier. From among the sword beasts' Reiatsu, they could sense several familiar spiritual patterns but none belonging to their own Zanpakutō, nor to Unohana's. That absence was abnormal, and both veterans knew what that implied.
Kyōraku's mind sharpened instantly. "It must be connected to the old man's disappearance…"
Muramasa's indifferent voice broke the silence. "Ah, their sword spirits? I sent them to him."
The words fell like cold rain. The difference in terminology sword spirits instead of sword beasts was subtle, but deliberate. It carried weight, pride. He regarded Zanpakutō as equals, not beasts.
The crowd rippled with shock.
Kyōraku, Jūshirō, and Unohana exchanged looks, their Reiatsu flickering uneasily as Muramasa continued in a detached tone, "That old man's Zanpakutō was too loyal, refused to join us. So, I had the sword spirits of the three of you seal him away."
The words chilled every Shinigami present.
Yamamoto Genryūsai Shigekuni the strongest Shinigami in the millennia. Ryūjin Jakka the most powerful fire-type Zanpakutō in existence. To say it had been sealed was unthinkable. Yet Muramasa said it so casually, as if discussing the weather.
And yet, no one doubted Ryūjin Jakka's loyalty. It was Yamamoto's lifelong partner, a blade that burned alongside his soul for centuries. That such a weapon would refuse to rebel was natural.
But Muramasa's mocking laughter shattered the brief silence. "That one is just as rotten as his master," he sneered. "A relic of a corpse stale, rigid, mindlessly loyal. Nothing more than an old dog clinging to decayed ideals."
"Bastard!" Kashiwamura Sajin roared, his voice trembling with fury. Yamamoto had raised him, trusted him, given him purpose. Every honor, every ounce of his pride as a Shinigami, had come from that man. To insult the Head Captain was to insult the faith that defined him.
He staggered upright, clutching his blade. His Reiatsu flared weakly but defiantly. Before he could strike, another presence surged past.
"Don't you dare run wild in Seireitei, you bastard!"
A white blur cut through the mist. Hitsugaya Tōshirō's furious shout split the air as his blade swung toward Muramasa.
But Muramasa didn't move. His eyes narrowed slightly, almost amused.
In that instant, a tall, cold figure appeared before Tōshirō.
A storm of frost exploded outward.
The young captain's pupils constricted as ice burst from the man's hand, spreading across the ground in a wave of glittering blue. He leapt back, but the frost caught his wrists, freezing them solid.
Tōshirō stared at the figure before him his own face reflected in those cold, glacial eyes. "You… Hyōrinmaru?!"
His voice trembled with disbelief and rage.
Hyōrinmaru said nothing. His expression remained emotionless, serene as frozen water. That icy stillness alone was a denial sharper than any word.
Before Tōshirō could react further, two more figures lunged from the ranks of the Gotei 13.
"Go to hell, bastards!"
"Let's see you sneer after this!"
Twin blades struck toward Muramasa but their blows were intercepted midair. Sparks flared as steel clashed.
Renji Abarai and Madarame Ikkaku froze in shock as they saw who stood against them. A muscular man with a jagged hairstyle… and beside him, a sultry woman with fierce eyes and a petite girl brimming with power.
Their Zanpakutō.
Renji's teeth clenched. "Damn it…" His voice sank low, anger trembling in every syllable. "How did it come to this?"
Muramasa watched with quiet disdain, his eyes sweeping across the battlefield filled with divided souls. "See?" he said coldly. "The moment your blades gain freedom, they turn their edge toward you. The Shinigami who claim to be kings were nothing but parasites."
He smiled faintly. "In that case…" His head lowered, eyes glowing faintly crimson. "Let this revolution begin."
The hill trembled as his voice echoed.
A heartbeat later, the world erupted.
Countless icicles burst from the ground, lightning split the clouds, cherry blossoms scattered like blades in the wind, and violet mists of poison curled through the air.
The once-silent hill of Sōkyoku plunged into chaos
a war of masters and their own blades,
a rebellion born from the heart of every Shinigami's soul.
The Zanpakutō Rebellion had begun.
