"You."
After Kurozawa's punch pierced his chest and directly removed his heart, the tall man's life force rapidly declined at a visible rate.
Those extremely sharp slashes all required the human body as a support.
When the power source was destroyed, in an instant, the sky full of sharp metal blade shadows vanished into thin air.
Swish! The sharp blade that Lefty had transformed into instantly swept across the tall man's neck. A fountain of blood shot up, directly staining the ceiling crimson.
One man and one Left Hand, one gouging out a heart, the other beheading. When fighting seriously, without holding back at all, they instantly extinguished the tall man's life force.
Plop, the Parasitic Organism's true form dropped to the ground.
The once glossy, blood-red fleshy tentacles that looked like they were made of tough muscle began to wither, their color quickly becoming dull and grayish-white.
Clang! A metal blade extended out. It used this as support, wanting to move its body to escape, but sadly, the metal blade that could easily destroy walls and cut through metal like mud just moments ago was now soft. It could only barely make a tiny, almost invisible hole in the ground.
After all, it was a Parasitic Organism. After losing its host, all its skills plummeted, shrinking significantly.
Now even a cat or dog could kill it.
The tall man's body also fell to the ground, the severed head still spurting blood, gradually forming a large pool of blood.
Kurozawa frowned and moved away, not letting these stain his clothes.
At the same time, the Parasitic Organism raised its head, managing to form a mouth. Its voice was intermittent, as if speaking to Lefty: "You... fellow... assist..."
It didn't finish its sentence before Lefty quickly interrupted, "Fellow? Different paths."
Lefty knew very clearly who was the father and who was the son.
Cling tightly to Kurozawa's thigh and don't let go! Kurozawa squatted down and poked the Parasitic Organism, which looked like a puddle of slime, with his hand. He said in surprise, "Looking like this, it's hard to connect it to that ferocious appearance just now."
It felt soft and rotten, as if a slight push could pierce it.
At the same time, a sound of footsteps echoed behind him, slowly approaching.
The Parasitic Organism under his finger seemed to see something and suddenly shouted, "Ryoko Tamiya, save me! Let me parasitize one of your limbs!"
Having seen Kurozawa and Shinichi Izumi's appearance, and their way of coexisting with Parasitic Organisms, it knew it actually had a slim chance of survival.
It had helped Ryoko Tamiya conceive that child, making it the biological father according to humans. It had what humans called a bond. Ryoko Tamiya, considering this relationship... probably wouldn't save it! What kind of bond could exist between Parasitic Organisms?
Kurozawa stood up, stepped on the Parasitic Organism trying to escape, and turned to look behind him.
Long ash-purple hair, sharp and indifferent eyes, and professional teacher's attire – the sound of footsteps was Ryoko Tamiya's low heels hitting the ground.
"What, do you want to save this fellow of yours?"
Kurozawa's eyes narrowed slightly, as if flames were rising in them, making him sharp and intimidating.
But the next second, his imposing aura dissipated, and he returned to his lazy, casual posture: "If you want to save him, just say so. I'll give you face."
That's what he said, but could he put the knife down first? Ryoko Tamiya looked at Kurozawa, who was pretending to be magnanimous with Lefty transformed into a metal blade, and suddenly felt that this strange human with great strength seemed to be a little petty.
Shaking her head, Ryoko Tamiya's voice was flat, saying, "I only came to see your fighting style."
"However, I was a step late, so I didn't see the wonderful battle." Her words seemed regretful, but her expression remained unmoved.
"Since you want to see, I'll give you a demonstration."
With a movement of his arm, the moon-white slash of a blade suddenly appeared and attacked Ryoko Tamiya's arm.
Across from him, Ryoko Tamiya's eyes immediately narrowed.
A strand of her hair instantly transformed into a sharp blade, intercepting and shattering the blade light.
"Aren't you going to take this opportunity to do some experiments?"
Kurozawa moved his leg. The Parasitic Organism beneath him was further indented, its breath faint.
But it was alive. If undisturbed, it could live for another minute or two.
Ryoko Tamiya glanced at this fellow of hers, and a hint of... disgust?... seemed to appear in her eyes.
Across from her, Kurozawa was slightly taken aback.
He didn't know if Ryoko Tamiya's emotional management was so strong that she could make micro-expressions and convey thoughts with her eyes, or if she had already been heavily influenced by human society and developed emotional thinking.
"No need. Transferring bodies only requires theoretical knowledge as support, not excessive experimentation."
As long as the theory was feasible, the Parasitic Organism, whose movements were as precise as a machine, could accomplish it.
Her voice paused, and Ryoko Tamiya added, coldly stating, "Besides, for a fellow like this, dying is a good thing."
The Parasitic Organism under his foot immediately showed a look of despair.
Although it didn't value human lives, it was very afraid of death. Any creature has an instinct for survival, and this was especially strong for Parasitic Organisms.
A clear smile appeared on Kurozawa's face, and he said, "Looks like you've figured it out."
The disturbance caused by the tall man was definitely not something Ryoko Tamiya wanted to see. She wholeheartedly wanted to integrate into human society and live a low-key life, and the tall man's actions were no different from throwing a bomb into human society.
Schools were always places that received a lot of attention.
With a school under attack, the state machinery was probably already restless, and various measures against Parasitic Organisms would be expedited.
Ryoko Tamiya nodded and sighed softly: "Such uncontrollable, self-willed fellows will only affect the survival of our species."
"It's a dangerous individual that must be eliminated."
Looking up, Ryoko Tamiya gazed at Kurozawa and said seriously, "I agree to what you've proposed. I will contact you later and provide the locations of some of our kind."
"Thank you."
Kurozawa waved his hand, and at the same time, he exerted force with his foot, crushing the Parasitic Organism that had been clinging to life.
"It's just cooperation, but rather than you trying to gain control, I hope you learn the transplant technique as soon as possible."
Ryoko Tamiya's delicate brows furrowed slightly in confusion. "You are already very strong. Why are you still so insistent on incorporating more of my kind?"
She couldn't see through Kurozawa at all. Her previous firm trust in Goto's combat strength had now wavered considerably.
Kurozawa turned around, looked at the clear, cloudless sky, and smiled. "You've been searching for a way for our species to survive. Regarding that, I do have an undeveloped suggestion."
He had a bold idea.
Compared to when he was somewhat lost in the Demon Slayer World, unsure of his goals, the current Kurozawa had clearly defined his aspirations.
He wanted brilliant, unique lives, one after another.
Since he had come this far, wouldn't it be a waste of his ability to travel between worlds if he didn't do something that would shake the entire world and leave a deep imprint on its cycle?
Perhaps a demon lord who destroys the world, perhaps a hero who saves sentient beings, perhaps an ordinary passerby who was always unknown but made a move that astonished the world... He wasn't bound by form, only by what pleased himself.
Across from him, Ryoko Tamiya suddenly felt that the man before her seemed somewhat different.
But exactly how he was different, she couldn't say.
