I'm not going to be an Spirit! (Translate)

Time passed quickly and three days passed.

Within three days, Kyōjurō Rengoku found the rebellious demon in Asakusa and successfully completed the mission.

For a demon slayer, there is no rest or vacation.

This is especially true for pillar-level members with extremely high combat capabilities.

After dealing with the demon in Asakusa, Kyōjurō Rengoku received his next mission and headed to the next destination without stopping.

Demons are solitary creatures and each has its own territory.

After getting rid of a Demons, it is equivalent to liberating the surrounding area, and there is no need to worry about Demons appearing in the short term.

Therefore, Kyōjurō Rengoku was also very relieved to leave Kotori Itsuka here.

After her elder brother left, Kotori Itsuka, who had been playing the role of a good girl in the Demon Slayer Corps base these days, immediately put on a black hairband, picked up a lollipop, and went to Tamayo and Yushiro hidden base in this city.

"Well, maybe this is it?"

After checking out the surrounding buildings, they seemed to agree with Tamayo description.

Standing in the interconnected alley, Kotori Itsuka tentatively tried to reach her hand into the wall.

But this wall was not an illusion, it felt solid to the touch.

After searching around for a long time, Kotori Itsuka finally found the hidden intersection.

Stepping into the phantom wall created by Yushiro blood demon art, Kotori Itsuka saw a mansion isolated from the world.

Unlike the Rengoku family's Japanese-style mansion, the Tamayo family's mansion is more modern.

As if sensing someone approaching, Yushiro poked his head out from behind the window on the second floor of the mansion.

He originally thought it was a lost passerby or a drunkard who had strayed into this place by mistake.

This kind of thing has not happened before.

However, when he saw that the person coming was Kotori Itsuka, his expression changed instantly.

"Tamayo-sama! Tamayo-sama!"

There was a noisy sound in the mansion.

Soon, the door of the mansion opened, and Tamayo, Yushiro, and the Kamado siblings all stood inside.

"You, why are you here in the daytime?" Yushiro voice was filled with shock that could not be concealed.

"If I don't come during the day, do I have to come at night?" Kotori Itsuka glanced at him strangely.

"Isn't that nonsense?!" Yushiro became excited, "Demons are active at night!"

"ah..."

After hearing what Yushiro said, Kotori Itsuka suddenly realized that she had fallen into a habitual way of thinking.

For ordinary people, visiting others happens during the day.

But for Demons, they will turn into ashes once they appear in the sunlight, so they can only move at night.

However, Kotori Itsuka immediately became confused.

"Don't you know that I'm not afraid of the sun?" She looked at Tanjiro Kamado in confusion, "You didn't tell them?"

"Tell me what, I don't know you..."

Tanjiro Kamado was about to say something.

However, he suddenly recalled that the first time he met Kotori Itsuka was at dawn, and at that time she had already shown her fearlessness of the sun, so he suddenly realized.

"At that time, I had just woken up from a coma, my mind was not very clear, and I was completely unaware..."

Tanjiro Kamado touched his head, feeling a little embarrassed.

And in Tamayo eyes, an inexplicable light flickered.

The urge to draw blood for research became stronger and stronger.

There is more than one Demons that doesn't eat people.

None of the Demons present need to eat humans to remain sane.

However, there has never been a Demons that is not afraid of the sun from ancient times to the present.

The Demons King, Muzan, has lived for thousands of years, but is still afraid of the sunlight.

This is also his only weakness.

"Could it be that... you found the blue spider lily?"

There were mixed emotions in Tamayo voice.

According to Muzan Kibutsuji himself, the blue spider lily is a medicinal herb that can help the demon overcome his fear of sunlight and become the ultimate creature that is truly immortal.

He has been searching for this magical herb ever since he became a Demons.

In fact, the only reason for creating the Demons race was to increase his subordinates in this way to assist him in finding the trace of the blue spider lily.

If there is a Demons that can overcome the sunlight, then the only explanation that Tamayo can think of is that the other party found and ate the legendary blue spider lily by chance, thus overcoming the biggest weakness of being a Demons.

"Well... I'm not sure about that."

Kotori Itsuka did not answer her question directly but gave an ambiguous answer.

In fact, swallowing blue spider lilies is not the only way to overcome sunlight.

In the original work, Nezuko did not rely on the blue spider lily, but embarked on the path of evolution on her own and overcame her weakness of fear of sunlight.

As for the reason why Nezuko was able to bask in the sun within just a few years after becoming a demon, while Muzan, an old demon who had survived for thousands of years, could only hide in the dark, it can only be said that this guy was too weak.

As expected, after knowing that Kotori Itsuka was immune to the damage caused by sunlight, Tamayo immediately prepared the props for drawing blood.

After inviting Kotori Itsuka into the mansion, Tamayo drew three full tubes of blood from her without any further formalities.

"Thank you. With the new sample, the progress of making the antidote to turn Demons into humans should be faster."

Holding the blood belonging to Kotori Itsuka, Tamayo bowed deeply and took Yushiro into her laboratory.

Kotori Itsuka rubbed her eyebrows, feeling helpless.

Because she really is not a Demons.

It's impossible to use the blood of Spirit to research the potion that can turn Demons into humans.

Kotori Itsuka could only hope that Tamayo would realize something was wrong sooner and give up studying her blood.

"Ah…ah…"

Just as the blood was drawn and Kotori Itsuka was about to find Tanjiro Kamado to discuss how Ratatoskr should act in the future, she heard a painful growl coming from somewhere in the mansion.

"Is there anyone else here?"

"Yes, there is another patient admitted by Ms. Tamayo." Tanjiro Kamado answered, "He had a small amount of blood implanted into him by Muzan, but I controlled him before he went crazy. He was then transferred to Ms. Tamayo and is being treated little by little with medication."

"Hmph... In other words, the curse of the Muzan cells still remains in his body?"

"I don't quite understand these, but from what Miss Tamayo said, there should be some left."

Hearing this, Kotori Itsuka nodded slightly.

Then, as if he had thought of a plan, an interested smile appeared on the corner of his mouth.

"Take me to see the patient."

Kotori Itsuka instructed.

"There's an experiment I want to try."
