Meanwhile back to the Mayuri's evil lab

In a dimly lit corner of Mayuri Kurotsuchi's laboratory, Uryu Ishida found himself engaged in a solemn conversation with Nemu Kurotsuchi. The room was filled with an eerie silence, broken only by the faint hum of machinery and the occasional drip of liquid from nearby apparatus.

Ishida's usually confident posture was now replaced by a visible sense of shame and regret. His brow furrowed with deep lines of anguish, and his eyes held a hint of sadness. He couldn't help but feel burdened by the weight of his involvement in Mayuri's Quincy breeding experiments.

Nemu, standing nearby with her usual impassive expression, observed Ishida's turmoil. Her gaze, seemingly devoid of emotions, held a subtle hint of understanding. With her soft, monotone voice, she broke the silence.

"Ishida, it is not your fault," Nemu stated matter-of-factly, her words cutting through the heavy air. "You were practically **** into participating against your will. Mayuri-sama's control over you through the ingestion of that pill made your actions involuntary."

Ishida listened intently, his gaze fixed on Nemu. Her words offered a glimmer of solace, a small flicker of relief amidst his inner turmoil. Yet, the weight of his involvement still pressed heavily upon his shoulders. "I understand," Ishida responded, his voice laced with a tinge of remorse. "But that doesn't absolve me of the guilt I feel. I should have resisted, fought back against Mayuri's manipulations. I allowed myself to become a pawn in his twisted game."

Nemu tilted her head slightly, her analytical mind processing Ishida's words. She spoke with a hint of sympathy in her monotone voice, a rare display of empathy from her stoic demeanor.

"Ishida, you must remember that Mayuri-sama's methods are designed to exploit and control. The fact that you were able to recognize the wrongdoing, to feel regret, speaks volumes about your character and integrity. It is a testament to your strength that you carry this burden of remorse."

Ishida nodded, his eyes glistening with a mix of gratitude and sorrow. He appreciated Nemu's attempt to console him, to offer some semblance of understanding in this labyrinth of guilt. However, the regret still lingered, gnawing at his conscience.

Meanwhile, in another corner of Mayuri’s laboratory, the atmosphere couldn’t have been more different.

"Boring! Boring! Boring!" echoed through the walls of Mayuri Kurotsuchi's laboratory as he swung a whip in his hand, sending various equipment and vials crashing to the floor in a fit of rage. The usually captain of the Twelfth Division was always a quick-tempered and eccentric individual who got irritated even at the smallest things. But this time he was even more visibly agitated, his eyes filled with frustration and disappointment.

Mayuri's experiment involving the insertion of his soul copy into the bodies of Candice and Bambietta, two Sternritters he had captured, had not gone according to his expectations. The soul copies were designed to mimic his personality and abilities, but they had turned out to be mere replicas lacking the unpredictable essence that made Mayuri himself so intriguing. There was nothing more turning-off for Mayuri than trying to have a wild threesome with these two ripe, voluptuous Sternritter bodies only to find that they were acting exactly like him.

"You imbeciles!" Mayuri spat, his voice seething with irritation. "Is this the best you can do? Acting like mirror copies of me? How utterly dull!"

“We’re sorry,” the soul copies inside Candice and Bambietta's bodies lowered their heads, apologizing profusely for their failure to meet Mayuri's expectations. “We won’t fail to meet your expectations again, Captain Kurotsuchi.”

But Mayuri wasn't interested in apologies. He craved excitement and chaos, the thrill of witnessing the unexpected. The soul copies' attempts to emulate his eccentricities had fallen flat, leaving him disillusioned and unsatisfied.

“Pah!” he spat, once again swinging his whip and knocking things around, causing Bambietta and Candice to hurriedly duck to avoid it. “I should have known this is the best soul copies can do. I need to insert their real personalities while still letting them be possessed… hmmm…”

A wicked grin spread across Mayuri's face as a devious plan began to form in his twisted mind. He laughed, a chilling sound that reverberated through the laboratory, blending with the clatter of broken equipment. This setback was merely an opportunity to refine his experiment further, to push the boundaries of what was possible.

With newfound determination, Mayuri set to work, his nimble fingers assembling a complex and intricate device. His mind raced with calculations and possibilities as he sought to create a mechanism that would allow the soul copies within Candice and Bambietta to retain their own unique personalities while still being under his control.
