In truth, Yushiro loves Tamayo dearly, willing to do anything to protect her. He was obsessed with Tamayo and would attack and insult anyone who came near him except him.
In other words, Yushiro feels jealous of Tamayo's attentive treatment of El. Just because El was a legendary sun breath user, the owner of the technique had already helped her.
But, what was equally important to El at the moment was that despite Tamayo looking 19 years El's age, Tamayo's real age was approximately 500 years. In essence, El was treated more as a child patient than a man.
And El was embarrassed to have his clothes taken off by a very beautiful woman. Although El's facial expression was completely out of sync with his thoughts.
"Okay. I understand, you can lie down a little longer, Adrian." Tamayo said not wanting to remove the kimono El was wearing and lay back down.
"Thank you." El said thank you in a cold voice. "Sorry for being presumptuous, can I ask you for something? Please give me a piece of cloth to cover my left eye."
"Your left eye?" Tamayo watched El's left eye curiously.
"My left eye is too conspicuous, I just want to cover it." Of course, El wasn't really telling the truth.
Actually, because Six Tomoe Rinnegan was constantly in an active state, the eye of insight always entered a constant state that interfered with the body's recovery of cramps being much slower.
Perhaps, El could overcome this by limiting the vision of the eye of insight. After that, El would use Kaifuku no Kokyu to speed up the recovery of her body's cramps.
Kaifuku no kokyū or recovery breathing is the state of taking time to focus on calming one's breathing, which speeds up the recovery of stiff muscles, which prevents a demon exterminator's body from being immobilized for the next few moments after using successive breathing styles.
By using this method, the recovery of El's stiff muscles can be accelerated even more than before.
Unfortunately, with his whole body cramped, it would be difficult for El to focus on limiting both eyes of insight while performing Kaifuku no Kokyu.
What El usually did was to close his eyelids, and then the problem was solved. Because of the uniqueness of Six's eye of insight ability from his Six Tomoe Rinnegan.
That uniqueness was, although only the left eyeball possessed the Six Tomoe Rinnegan. However, it had an effect on both eyeballs.
But, right now El couldn't let his guard down. Because it was possible for Yushiro to get rid of him if there was no Tamayo around.
That was why, El would use his right eyeball as the vision of the extended eye of insight, of Six Tomoe Rinnegan.
Following her patient's request, Tamayo tore off a bit of the hem on the purple kimono she was wearing, to make El an eye patch. Yushiro screamed inwardly with his mouth gaping and eyes turning white.
Teeth chattering, Yushiro walked over to El who was lying on the futon. Annoyed, Yushiro grabbed the collar of El's neck kimono. "You bastard!"
Then shook El's helpless body. "How dare you make Tamayo-sama have to break the hem!"
"Yushiro, stop doing that!" Tamayo said that with a stern tone of voice and a sad look in her eyes.
"Yes, Tamayo-sama!" Immediately, Yushiro released the neck grip of El's kimono collar, making his fall to the floor.
"Gah, ugh!" El growled as the back of her head hit the floor quite hard.
"I'm sorry Yushiro, he's actually a good kid. It's just hard to communicate, I hope you guys can get along." Then Tamayo corrected El's lying position and then tied the blindfold over El's left eye.
"Yes, no problem. Thank you for making me an eye patch. But, I'm sorry, can I ask you about what I asked you before?" El with her right eye looked seriously at Tamayo.
For a moment, a silence with heavy air was created in the basement. Tamayo watched seriously. In his mind, Tamayo wondered about what El's purpose was in actually asking for his blood.
This man lying on the futon should have known the purpose of asking for her blood. From the sword moves shown last night, it was certain that El was a Demon Hunter.
"Why do you want my blood? Don't you want to be human anymore? However, living not as a human would be very painful and difficult." Tamayo said that with a sad look in her eyes and a serious tone.
"No, that's not it. I'm not asking for your blood because I want to stop being human. But for me to keep it and maybe, I can help someone with it." El said seriously.
At the time of saying that, El was dishonest and lied. You could say, El mixed lies with the truth. Because it's impossible for El to tell the truth.
The purpose of asking for Tamayo and Yushiro's blood was none other than the quota requirement to complete the third main mission, collecting demon blood.
The more and stronger the Demon rank, the better. Especially, considering Tamayo is a demon that existed before 12 Kizuki was formed. Surely Tamayo is as strong as the 12 Kizuki of the upper moon.
Tamayo was silent, her sad eyes gazing seriously at El. In her mind, Tamayo wondered about El's true motives for asking for her blood, which felt suspicious and strange.
Meanwhile, Yushiro was also silent looking at El overlapping with her. Yushiro recalled the memory right before becoming a demon. Because of Yushiro's unknown illness that Tamayo had unsuccessfully treated.
When Yushiro was about to die, Tamayo asked Yushiro 'if he wanted to save his life' but on the condition of turning Yushiro into a demon or letting him succumb to his illness and die as a human.
Convinced, Yushiro decided to become a demon. From then on, Tamayo accepted Yushiro as an assistant and a medical practitioner until now.
Another outside and another inside. El's expression looked very serious cold and flat like the ice in the Arctic untouched by time. But in her heart, El really hoped that Tamayo would give her some blood.
That way, El would not lose the side mission reward. Moreover, El could speed up two of the main missions that needed to be completed in order to return to the Rencarnation Room and start the reward evaluation.
"Yushiro, please get me two syringes." Tamayo commanded Yushiro with a soft tone of voice like a lullaby melody.
Yushiro nodded his head and obeyed Tamayo's orders without asking any questions. Yushiro withdrew, going to fetch a syringe. "Alright, Tamayo-sama."
"Does that mean you gave your blood voluntarily, Tamayo-san?" El asked with a tone of voice demanding reassurance.
"Yes." Tamayo answered briefly.
Shortly after, Yushiro had returned and brought 2 glass syringes measuring between 2 and 3 ml, usually most used for vaccine injections.
Tamayo injected the syringe into her right arm to draw blood. Followed by Yushiro doing the same. After taking a sample of his blood, Tamayo handed it to El.
Tamayo placed the two syringes right next to the futon, where El was lying. "These two injections contain my blood and Yushiro's blood."
"I don't really understand what your purpose is in asking for our blood. In any case, please use my blood wisely." Tamayo advised and warned El to be careful.
El understood the advice and warning. El, who rarely smiled, gave Tamayo a gentle smile. "Don't worry, I'll use your blood wisely."
Ding!

Then Tamayo smiled wryly and stood up. "I hope you can keep your word. I'll be leaving, so get plenty of rest to recover quickly."
"Since you just woke up from fainting, I'll bring you food and drink in an hour." Tamayo turned around with Yushiro, they then left El to rest.
After Tamayo and Yushiro had moved away, El moved his right hand and looked at palm. El clenched and opened his palm, he checked the movement of his joints that had recovered.
"Hmm." El nodded. "Kaifuku no Kokyu is working very well. Now I can move my body." El said, smiling gently.
