Chapter 218: 218 Resurrection Medicine
Afterward, at Ubuyashiki Kagaya’s request, Reiger helped all the Pillars dissolve the marks on their bodies.
These were deadly, and had Reiger not helped them dissolve them, they would definitely not have lived past 25 years of age, and Himejima Gyoumei, who was already 27, would have died immediately, without any chance of survival.
Since the birth of the marks, there was only one person who had managed to live with it, and that was Tsukiguni Yoriichi.
Reiger did not know how Tsukiguni Yoriichi had managed it, and it wasn’t mentioned in the original story either.
Perhaps, Tsukiguni Yoriichi survived because his mark was congenital.
Perhaps, the mark did not deplete all of Tsukiguni Yoriichi’s life potential, which allowed him to survive.
Or perhaps, Tsukiguni Yoriichi had found a way to break the side effects of the marks before he turned 25, but that too was uncertain.
But Tsukiguni Yoriichi was Tsukiguni Yoriichi, a real standout, and the Pillars of the Demon Slayer Corps definitely could not compare; continuing with the marks was simply courting death.
Thus, Reiger used his magic to dissolve the marks from the Pillars’ bodies.
In this way, the Pillars could now live past 25, but at the same time, without the marks, their strength was greatly reduced, nearly bringing them back to their original state.
Without the marks, the Pillars couldn’t even activate their Swordsman’s Blade, and out of the trio of abilities, only the Transparent World could still be used by them. Uzui Tengen, Kochou Shinobu, and Kanroji Mitsuri could not even use the Transparent World, so saying they were brought back to their original form was no exaggeration.
However, now that there were no longer any malevolent spirits, they no longer needed the power.
The Demon Slayer Corps was officially disbanded, and after this event, all the Ghost Hunters would put down their swords, return to normal society, and lead normal lives.
Rengoku Kyoujurou would take over the Rengoku Family’s business and try to transform this historic Ghost Hunter family.
It is said that he intended to open a dojo, where he would teach swordsmanship to apprentices who came to learn, making the dojo the main business of the Rengoku Family for the future.
Kochou Shinobu would continue to run the Butterfly Mansion, but from now on, the Butterfly Mansion would not only serve the Demon Slayer Corps but would offer medical treatment for the general public.
It seemed Iguro Obanai had made up his mind and planned to confess his feelings to Kanroji Mitsuri. If the two could bind together, they would most likely get married soon.
Uzui Tengen was already married, with three wives, and the four of them planned to find a place to settle down and live a secluded life in the future.
Himejima Gyoumei, Shinazugawa Sanemi, and Tokitou Muichirou expressed their intention to stay with the Ubuyashiki family and continue to serve the Ubuyashiki family’s business.
As for Tomioka Giyuu, he seemed to want to go back to his master and what he would do in the future was something only he knew.
The Pillars made their plans in such a manner, and even Tanjirou, Zenitsu, and Inosuke planned to take Nezuko back to the Kamado family, to live as before.
Of course, the Ubuyashiki family would not ignore them after the disbandment of the Demon Slayer Corps; whether it was the Pillars, Tanjirou and others, or even the general members and the hidden ones, the Ubuyashiki family had already planned to help them integrate into normal society and lead normal lives, at least financially, they would probably never have to worry again.
In such circumstances, even the village of swordsmiths was preparing to open up to the outside world and no longer conceal their whereabouts but make the forging business their main source of income, nationwide.
All of this would be conducted smoothly with the assistance of the Ubuyashiki family in the future.
It could be said that the surviving individuals would all have a bright future ahead, living a life free from worries throughout their lives, and that wouldn’t pose a problem at all.
Ubuyashiki Kagaya, Rengoku Kyoujurou, and Tanjirou and others even asked Reiger about his future plans.
To this, Reiger only gave one reply.
"I will return to where I belong."
After saying just that, Reiger never spoke of anything else.
This gave Ubuyashiki Kagaya, Rengoku Kyoujurou, Tanjirou, and others a certain feeling.
That was, once Reiger left, they would probably never meet again in the future.
But, they did not become overly sentimental because of this.
"The Ubuyashiki family will always remember you."
Ubuyashiki Kagaya thus declared.
"You are always welcome to visit my dojo."
Rengoku Kyoujurou also embraced Reiger with a rare gentle expression.
"Thank you for everything, big brother."
Tanjirou was a bit sad and shed tears, but after wiping them away, he also gave Reiger a big smile.
Then, at this very last moment, Reiger told them something.
"Actually, I am not called Tsukiguni Yoriichi."
Reiger suddenly smiled at everyone.
"My name is Reiger."
Finally, Reiger revealed his real name.
"Reiger..."
Ubuyashiki Kagaya, Rengoku Kyoujurou, Tanjirou, and the others murmured silently, and by the time they came to their senses, Reiger had already disappeared.
On that day, Reiger left the village of swordsmiths alone.
And whether it was the people of the Demon Slayer Corps or the villagers, from then on, no one ever saw Reiger again.
But Reiger’s name, would stay forever.
Many years later, some miraculous things were discovered.
For instance, at a dojo named "Rengoku Dojo," the name "Reiger" was engraved at the foremost position on the wall of honor.
For example, the ancestors of the Ubuyashiki family often mentioned a great swordsman named "Reiger" to their descendants.
Further, in a coal-selling household deep in the mountains, there was a group photograph of all the members of the Demon Slayer Corps displayed, but the center spot was empty. Instead, an automaton holding a nameplate inscribed with "Reiger" was placed there.
Even in a private medical institution named "Kochou House," it was said that there existed a pharmacist who had made tremendous contributions to the medical field. She never married, dedicating her life to researching a herb that could cure all diseases, which she named "Reiger."
These, however, were things that would only happen long, long in the future.
......
Meanwhile, having left the village of the swordsmiths, Reiger stopped suddenly as he entered a dense forest.
Because in front of him, two people appeared.
It was Tamayo and Yushirou.
"Are you leaving?"
The elegant visage of Tamayo no longer held the sorrow and resentment of the past, only a sense of relief as if a burden had been lifted.
"Yes," Reiger nodded at Tamayo like this and said, "Have you come to see me for the last time?"
"...Sort of," Tamayo pursed her lips and said, "I want to thank you, but you probably have heard enough of that, so I’ll just keep it in my heart."
"Is that so?" Reiger smiled slightly and asked, "What plans do you have for the future?"
Upon hearing this, Tamayo lowered her eyelids.
"I have successfully developed a medicine that turns people back into humans," Tamayo said. "The blood of Kibutsuji Muzan that remained on the battlefield of Infinity City has been completely analyzed by me, and I ultimately managed to develop the medicine."
"Oh?" Reiger was slightly startled, then understood and asked, "So, do you plan to take the medicine and turn back into a human?"
"...Whether it’s me or Yushirou, we wouldn’t hesitate to turn back into humans if given the chance," Tamayo said quietly: "This world should no longer have ’demons’ in it."
The death of Kibutsuji Muzan led to the annihilation of all demons.
Tamayo and Yushirou were the exceptions.
Tamayo had already taken advantage of the weakened state of Kibutsuji Muzan, who had been critically injured by Tsukiguni Yoriichi centuries ago and could no longer control her. Using her knowledge in medicine, she transformed her body and completely freed herself from Kibutsuji Muzan.
Yushirou was the only demon in the world not created by the blood of Kibutsuji Muzan but transformed by Tamayo from a dying human into a demon during her centuries of research on demons.
Thus, the death of Kibutsuji Muzan did not affect these two.
In this world now, Tamayo and Yushirou were the only remaining demons, while all the other demons had disappeared.
No one knew about this, except for Reiger.
No, perhaps the Ubuyashiki family knew, but it seemed that Ubuyashiki Kagaya had no intention of interfering with Tamayo and Yushirou.
Clearly, Ubuyashiki Kagaya chose to trust Tamayo, believing that even though she was a demon, she would not become an evil one.
With this, Tamayo and Yushirou could continue to live as demons, never having to fear aging or dying.
Tamayo also knew about the existence of the blue spider lily, and with her medical skills, it wouldn’t be difficult to develop a drug that could conquer sunlight.
In time, the eternal life and perfect existence that Kibutsuji Muzan had dreamed of might be realized in Tamayo and Yushirou.
However, Tamayo did not seem to plan on doing so.
She didn’t want to be a demon; she just wanted to be human.
Even if it meant death, that didn’t matter.
Having avenged her great grudge and lived for hundreds more years, Tamayo felt she had lived enough, and now she simply wanted to die quietly as a human.
With Tamayo making such a decision, it was natural that Yushirou would not choose to continue being a demon alone.
Therefore, once the effects of the medicine that turns demons back into humans were fully confirmed, with no issues, both of them would likely take the medicine and turn back into humans.
With this, the last two demons in the world would also disappear.
"Please take this."
Tamayo handed a small vial to Reiger.
"What is this?"
Reiger asked, puzzled.
"This is a medicine I developed after completely diluting the blood of Kibutsuji Muzan, allowing a person to temporarily gain regeneration abilities comparable to a demon," Tamayo explained. "There is only this one dose in the world. If you take it, even the most severe injuries will heal immediately, and it could even revive someone who hasn’t been dead for long."
A medicine that could revive the dead!
This was a big deal indeed!
"Consider it a thank-you gift," Tamayo bowed to Reiger and said goodbye, "Farewell, until we meet again."
After speaking, Tamayo disappeared with Yushirou.
Reiger watched them leave and only after a long while did he put away the medicine.
