Mayuri Kurotsuchi was riding a black dog bigger than an ox towards the Shin'ō District.
He wasn't particularly interested in the intrusion into Seireitei, especially since the intruders had challenged Captain-Commander Yamamoto to a duel; he simply didn't care.
He disliked wasting his energy on things that didn't require his attention and only wanted to complete the Super Hound experiment as soon as possible.
This thought persisted until Shiraishi released his Reiatsu.
Mayuri Kurotsuchi realized that the annoying guy was in Seireitei. Instead of continuing to conduct experiments behind closed doors, he released the large black dog that was still being modified to see if it would have any effect.
Or it may be that a shortcoming has been discovered that needs improvement.
The current black dog is considered the closest to a Super Hound among all modified dogs.
His body had been injected with various enhancement drugs, but it hadn't collapsed yet. However, the muscles in his limbs were so exaggerated that they resembled those of a human wearing a muscle suit. Most of his body hair had fallen out, and the exposed skin was still jet black.
It looks very unattractive.
Superhounds weren't created for beauty pageants; their purpose was to track the scent of Shiraishi.
The big black dog's sense of smell was enhanced, enabling it to identify more than four million scents at a very fast pace, comparable to that of a typical vice-captain.
Its mouth cannot close properly, and it constantly drools a corrosive green saliva, which needs to be improved.
They rushed into the Shin'ō District, and the man and dog arrived outside the ground-level building of the Central 46 Chambers.
The scene was one of ruins.
The most severe damage stretched for hundreds of kilometers, destroying countless buildings along the way, but also carving out a remarkably clean, straight path.
"Woof woof!" The big black dog landed in the middle of the road and the Roar at a figure on the ground, spitting as it made a sizzling sound as the ground corroded.
Mayuri Kurotsuchi jumped off the dog's back and strode toward the fallen Nemu Kurotsuchi. His face, painted with black fake skin, made it impossible to tell what he was thinking.
Isane Kotetsu turned around, his expression tense, and said, " Captain Kurotsuchi, Nemu is seriously injured and needs to return to the Fourth Division for treatment."
"Get out of here!"
Mayuri Kurotsuchi's tone was clearly displeased. The treatment at the General Infirmary couldn't compare to the experimental table at the Twelfth Division, where he could quickly restore Nemu Kurotsuchi's health. "My adjutant doesn't need your treatment."
"This is our duty."
Isane Kotetsu gritted her teeth and continued to block him.
The big black dog made a threatening growling sound, its paws scratching the ground, leaving a trail of claw marks.
Mayuri Kurotsuchi's golden eyes flashed with murderous intent, his right hand gripping the Zanpakuto tucked into his Zanpakuto. "I'll say it again, get out of the way."
The air temperature dropped sharply.
A chill ran from her fingertips down her shoulders and into her heart. A deep-seated fear made her tremble. If she didn't move aside, the man in front of her would really kill her.
If you move aside, what kind of treatment will Nemu receive when she goes back?
Thinking of this, Isane Kotetsu overcame her fear, bit her lip, and continued to block him.
Mayuri Kurotsuchi's anger intensified. How dare a mere Third Seat be so ungrateful? He immediately drew his sword.
One hand holds down the end of the knife handle.
The snow-white Captain's Haori floated down slowly, with the four ink-black characters in the center. Isane Kotetsu's taut courage instantly vanished, turning into a limp lamb, whimpering pitifully, " Captain Unohana."
Retsu Unohana didn't turn around, her expression calm as she said, " Captain Kurotsuchi, please don't interfere with our work."
This woman... Mayuri Kurotsuchi narrowed his eyes slightly. After weighing the pros and cons in his mind, he still released his grip on the hilt of his Zanpakuto was then sheathed.
Retsu Unohana's tone softened considerably as she said, "Thank you for your cooperation."
Mayuri Kurotsuchi was extremely annoyed, but there was nothing she could do. She turned around and glanced at the big black dog, which had long since lost its previous ferocious baring of teeth and lowered its head, looking like a very docile and obedient dog.
"Useless thing!"
He got angry, took out the controller and pressed it, and the big black dog's body quickly bulged with muscle bulges.
In the blink of an eye, before it even had time to howl, its Riot Games- sized eyes were squeezed so small by the muscle bulges that they were no bigger than soybeans.
With a loud bang.
The big black dog exploded, splattering blood and flesh everywhere, leaving a shallow crater in the ground.
" Captain Kurotsuchi, you've gone too far." Isane Kotetsu couldn't contain her anger. Forcibly using dogs for experiments was already extremely cruel, but to then casually kill the modified dogs was even worse.
This is something no human being could do.
Mayuri Kurotsuchi didn't think she had done anything wrong, and said with a sneer, "Useless trash is of no use at all."
In his vision, a super hound must possess characteristics such as being unafraid of Reiatsu, recognizing stimulating scents, and being incredibly fast.
The big black dog clearly failed in the first point, and wasn't particularly outstanding in the others either. If he was in a good mood, he might stay alive, but if he was in a bad mood, he would only die.
For something like this, making a new one would be incredibly easy.
"You."
" Isane," Retsu Unohana interrupted her, "Once the temporary first aid is finished, take her back to the General Infirmary for full treatment."
"No, no need."
A weak voice came from the stretcher below. Nemu Kurotsuchi barely opened her eyes. Perhaps because her injuries had been treated, her vision was not so blurry, and she could see the person standing next to her.
Isane Kotetsu quickly squatted down and said gently, " Nemu, you can't speak yet."
" Kotetsu, thank you for your concern, but I still have to go back."
Nemu Kurotsuchi's face was pale, but her gentle tone contained an unwavering determination, "I've been through a lot these past few days, and I think you and Shiraishi are both wrong."
Isane Kotetsu understood what she meant by "misspokenly," and fell silent.
She continued to murmur, "During those times outside, the scenery I saw, the people I met, the things I experienced, and the new dishes I learned to cook—the first thing I thought about was how to tell Mayuri- sama about it and share the joy in my heart."
Mayuri- sama is my only family in this world, and my most beloved father.
This is a fact that will never change...
" Nemu." Isane Kotetsu watched her fall into a deep sleep again, her feelings complicated. Being filial to one's father was right, but was a scumbag father truly worthy of filial piety?
The big black dog's body was still warm.
I wonder what kind of treatment she'll receive when she goes back.
Isane Kotetsu was caught in a fierce internal struggle.
Mayuri Kurotsuchi remained silent. He had never seen Nemu Kurotsuchi speak so much or show such a human expression. She didn't seem like a machine; she seemed more like a person.
Mayuri Kurotsuchi has always believed that emotions are unnecessary distractions that hinder scientific progress.
Only rational thinking can yield the most efficient and accurate answers.
Perhaps he was wrong?
Mayuri Kurotsuchi thought of Kisuke Urahara, and also of the Quincy she had studied, and a thought she had never had before arose in her mind.
He wanted to understand those emotions, love, friendship, beliefs, those mysterious and profound things. "I'll leave Nemu to you for treatment."
After saying that, Mayuri Kurotsuchi looked up in the direction of the Sōkyoku Hill. It looked like the event was almost over. Since they were already here, they might as well take one test subject back with them.
