Although it was daytime, the curtains in the clinic were drawn tight, protecting the two occupants from being burned by the sunlight.
Upon seeing Ren, both Tamayo and Yushiro widened their eyes in unison.
Yushiro, in particular, instantly became vigilant, staring at him with a gaze filled with hostility.
At this moment, the doctor spoke respectfully, "Miss Tamayo, I have brought the volunteer for the blood donation."
"Alright, leave the rest to me. Doctor Chiba, you have been busy all day, please go and rest."
"Okay, I will leave the rest to you then, Miss Tamayo." Doctor Chiba yawned wearily and left the consultation room.
After he left, the atmosphere in the room suddenly turned gloomy. Finally, Ren broke the silence, flashing a smile he believed to be kind.
"Miss Tamayo, let's proceed with the transfusion quickly. It wouldn't be good if something happened to the patient."
With that, Ren took the initiative to offer his arm. Seeing this, Tamayo was momentarily surprised before nodding repeatedly.
"You are right, I will begin immediately!"
Tamayo first sterilized the area with medical alcohol, then took out the IV tube and needle. She inserted the needle into Ren's vein, and his blood slowly flowed into the collection bag.
As the needle pierced his skin, a faint scent of blood permeated the air. To Tamayo and Yushiro, however, this scent was exceptionally delicious.
Even so, the two suppressed their craving for fresh blood, focusing their attention on the patient.
Seeing this, Ren smiled faintly and suddenly spoke, "Doctors, you are demons... right?"
"!!!"
At these words, both of their eyes widened. Yushiro looked ready to strike preemptively to cover Tamayo's escape.
However, Tamayo signaled Yushiro with her eyes not to act rashly. She then nodded gracefully and admitted it.
"That is correct, we are indeed demons. But please rest assured, we will not harm humans. My goal is the same as yours: to defeat that man, Kibutsuji Muzan!"
"So, I hope you can trust us!"
"Mn, no problem. I trust you!"
Ren nodded. As a transmigrator, he naturally knew that Tamayo and Yushiro were good people—no, good demons.
Especially Tamayo; she was essentially the MVP of the Infinity Castle battle and the Demon Slayer Corps' number one support. Compared to her, everyone else was basically just getting carried!
"Eh?"
Tamayo's eyes widened, and she spoke in disbelief, "You trust us so quickly? We are demons!"
"Lady Tamayo, don't be deceived by him!"
Yushiro suddenly spoke up, his tone filled with hostility. "He doesn't have a Nichirin Sword right now, so he definitely wants to gain our trust first to stall us. Once he retrieves his sword, he'll kill us!"
"Heh, you are judging a gentleman with the heart of a villain!"
Ren chuckled softly and pointed out the window. "Don't forget, it's broad daylight. If I wanted to kill you, would I need a Nichirin Sword? Couldn't I just kick you out of the clinic?"
"The reason I trust you is that I believe in my nose!"
"You don't have the stench or the bloody smell characteristic of evil demons. Furthermore, you just spoke Muzan's name. Plus, I am the Cloud Hashira of the Demon Slayer Corps. I have seen in the Corps' records that hundreds of years ago, a swordsman named Tsugikuni Yoriichi spared a female demon named Tamayo, and he guaranteed to the Master of the Demon Slayer Corps at the time that Miss Tamayo would absolutely never harm anyone."
"So, I chose to trust you. I trust that you will not harm humans."
"Mr. Yoriichi?!"
Tamayo was dumbstruck. She hadn't expected to hear Tsugikuni Yoriichi's name again after hundreds of years.
Slowly, she stood up and bowed slightly to Ren, expressing her gratitude. "Thank you, swordsman of the Demon Slayer Corps. Thank you for being willing to trust us! You really are a very kind child..."
Tamayo then explained how she had modified her body with medicine and mentioned that they had just been observing Ren's battle with the three Upper Moons using a Blood Demon Art.
"So that's how it is. You were watching from the side the whole time, and I didn't even notice..."
Hearing this, Yushiro immediately smiled proudly. "Hmph, this is my, Yushiro's, Blood Demon Art. How is it? Amazing, right?"
"It is indeed very amazing."
Ren nodded slightly. Being able to see the intensity of an enemy's techniques and even share vision just by sticking a talisman on the forehead was practically on par with the Six Paths of Pain.
This talisman could not only share allied vision but also block the enemy's vision if needed. Although it lacked offensive power, its support capability in combat was incredibly strong.
After praising Yushiro, Ren looked at Tamayo and bowed slightly. "Miss Tamayo, I have a presumptuous request. I have a friend who is deeply poisoned. I hope that one day in the future, you will be able to step in and save her."
"As payment, as long as you stay in this town, I will protect you from Muzan's threats."
"That is no problem. I am both a demon and a doctor; saving lives is my duty."
Tamayo agreed without hesitation, but then she changed the subject, asking in surprise, "However, logically speaking, when someone is ill, the sooner they are treated, the better. Why don't you let me help her detoxify now?"
"Heh, because she injected the poison into her body for the purpose of eliminating evil demons. To kill demons, she wouldn't even hesitate to sacrifice her own health. But I cannot watch helplessly as she hurts herself, so I hope Miss Tamayo can help me."
The friend Ren spoke of was Kocho Shinobu. Heaven only knew when the Wisteria poison in her body would flare up, so he had to prepare in advance.
"I understand. When the time comes, I will help her. However, I also have a request."
Tamayo paused for a moment before continuing, "You know that I have been developing a drug capable of weakening or even killing Muzan. However, due to the lack of Muzan's blood, I haven't made any progress."
"I hope that when you fight the Twelve Kizuki again, you can obtain their blood. That way, I can develop a drug to weaken demons, or even turn them back into humans."
"That's no problem. I will help you."
Ren agreed without hesitation. He was going to fight the Twelve Kizuki anyway; taking some blood for Tamayo after killing them was no trouble at all.
"Thank you. I hope we have a pleasant cooperation."
Tamayo smiled with gratitude. By now, the blood bag was sufficiently full. She immediately removed the needle from his arm and began transfusing the blood to the little girl's mother.
After receiving Ren's blood, the woman's pale face became rosy again at a speed visible to the naked eye.
Seeing that she was out of danger, Ren left the consultation room and went to Tanjiro's ward. He told Kamado Kie, Nezuko, and the others to go back and rest first, leaving the situation here to be handled by him and Kocho Shinobu.
After all, it was broad daylight, so he wasn't worried about them being attacked by evil demons.
