"These remains need to be disposed of properly, or they could easily give rise to new evil entities."
As the last traces of evil aura dissipated, Kikyo withdrew her spiritual power and eyed the mountain of demon limbs piled on the ground. Tapping her chin lightly, she frowned.
"Although the evil aura has been purified, the residual demonic energy still lingers. Fully purifying all of this would consume too much spiritual power. We need a more convenient method."
"Can't we just throw them away?" Kagetsu asked, confused.
In the past, when he needed demon life force, he would simply use a scroll to drain it into mummies. Once he no longer needed the corpses, he left them where they fell, never considering any consequences.
"Of course not," Kikyo replied sternly. "Most demons retain not only demonic power but also lingering evil aura. After death, these energies gather in the corpse and can mutate, giving birth to new demons. They must be handled properly."
Kagetsu glanced at the remains, realizing his old methods were equivalent to dumping highly toxic waste. He thought of a great demon from the story,Ryūkotsusei, the one who sacrificed himself to teach Inuyasha the Bakuryūha,a demon formed from the mutation of a dragon corpse.
"How do you usually handle demons after killing them?" he asked.
"For weak demons," Kikyo explained, "a Demon-Slaying Arrow can purify them directly into ashes,no extra steps needed. For stronger demons, it's more complicated. They must be buried with talismans to suppress the residual aura. Over time, the aura dissipates, and the corpse becomes safe. Alternatively, they can be thrown into special places, like the Bone Eaters Well near Kaede's Village, where I often disposed of corpses fifty years ago."
"Understood," Kagetsu nodded. "So we bury them and use talismans to suppress the aura until it fades naturally."
Kikyo turned to fetch the talismans, but Kagetsu placed a hand on hers. "No need for all that trouble. I have a better way."
"But we need to change locations,here isn't suitable."
The Mangekyō Sharingan emerged in his eyes, surging with ocular power.
"Kamui!"
A spatial vortex appeared, instantly sweeping all the demon remains into the Kamui Dimension.
"Come with me." Kagetsu led Kikyo toward the back of the shrine. "There's a rock pile in the forest behind the shrine,it's perfect for disposal."
They passed through the woods and arrived at a clearing filled with rocks and overgrown weeds.
"How are you going to handle them?" Kikyo asked, curious.
Kagetsu activated Kamui, bringing forth all the remains and piling them on the rocks. "We'll burn them."
"Ordinary flames can't completely burn demon corpses," Kikyo reminded him. "I'm not sure if your Ninjutsu flames will work."
"Don't worry. These flames will do the job." He stepped back, keeping a safe distance. The Mangekyō Sharingan patterns rotated slightly in his eyes, releasing a surge of ocular power. He shouted:
"Amaterasu!"
Jet-black flames erupted from the remains without warning, engulfing the entire "mountain of corpses." The intense heat warped the surrounding air.
"Is this… black flames?!" Kikyo's eyes widened in shock.
"These are the Sharingan's inextinguishable black flames," Kagetsu explained with a strange smile. "As long as I don't release them, they keep burning the target until it's reduced to ashes."
He had copied the technique from Sasuke but rarely used it.
"It's powerful!" Kikyo exclaimed, impressed.
"But it also has a nickname: 'The Amaterasu That Can't Burn Anyone to Death,'" Kagetsu added.
"Can't burn anyone to death?" Kikyo was confused, pointing at the remains quickly turning to ash. "Its power is clearly immense. How can it not be lethal?"
Kagetsu chuckled. "As long as you understand its principles, it's hard to die from it. For example, if it touches my clothes, I simply remove them before the flames reach my body. Even if the flames touch a non-vital area, one can survive by decisively removing the burning part."
Kikyo stared, speechless, but found the logic sound. "I see… that makes sense. I suppose few people are completely unclothed in battle."
"Exactly," he said with a wry smile. He recalled Naraku's naked incarnations, like Musō, who had perished recently,defenseless against fire.
Turning back to the demon remains, Kagetsu said, "For these immobile corpses, this is more than sufficient."
The black flames roared, consuming every trace of the lingering evil aura, ensuring that no future threat could arise from Naraku's remains.
