Before we knew it, a few days had passed so quickly. However, at this moment El was still lying on the futon in the basement, where Tamayo and Yushiro were treating their patient.
For the past few days, El had done nothing but lie down and look at the ceiling of his room. Doing nothing all day was a hidden talent El had. And, El him self was very fond of his talent.
The cramps all over El's body had completely healed. But, El was still pretending to be sick, helpless which made Yushiro often angry at El, warning her to leave as soon as possible.
As usual, El ignored Yushiro's anger. Treating Yushiro's every word and insult as a gentle breeze blowing in his ears.
As long as Yushiro did not act with murderous intent, El would not move and did not care about how Yushiro would treat his.
There was a reason El still remained in Tamayo's house. El's goal was simple, it was to wait for Tanjiro and Nezuko to come somehow. Once Tanjiro and Nezuko came, El would ask for Nezuko's blood.
"Hopefully, the system doesn't give me a troublesome mission like the previous one." El muttered while looking at the sky of the room.
Then El sighed. "I'm getting a bit bored, aren't I? Not doing anything for a few days other than lying down, sleeping all day and being fed."
Because now El is pretending to be sick so he can't move. In other words paralyzed. Every time El eats and drinks, even changing clothes and washing sweat will be helped.
At first it was Tamayo herself. This made El very embarrassed inside. But, the expression on his face remained cold and flat very different from the one inside.
Over time, seeing El constantly being served by Tamayo, Yushiro burned with the fire of jealousy and soon replaced Tamayo.
Not long after, El sensed the presence of another demon and a human entering Tamayo's house. The demon was with Yushiro, while the human was with Tamayo in the upper room.
From the sense of presence, Yushiro and the demon walked towards his basement.
"Hmm, is this the presence of another demon? Is Tamayo or Yushiro going to do medical practice? But, what are the humans for?" El muttered while wondering in thought.
El moved her eyeballs in the direction Yushiro and the Demon were coming from. Moments later, Yushiro was seen crossing in front of El's room with a male demon tied with ropes all over his body.
The demon looked very rebellious and roared. But no matter how hard the demon tried, the demon could not escape from Yushiro who was much stronger than ordinary demons.
"Yushiro, what are you going to do with that demon?" asked El curiously.
"None of your business." Yushiro answered El sarcastically.
"Then why bring a demon? Don't you hate demons so much? Especially since he's a man." El continued to ask because he was a little bored.
"I said it's none of your business! Hurry up and leave this house!" Yushiro said that in a sarcastic tone.
Quickly, Yushiro put the demon in the room directly opposite El's room. Then Yushiro left in a hurry.
"So it can be said that now I have a friend, right? Hey Demon, what's your name?" El asked the new Demon.
"Grr, roar!" However, the Demon's only answer was to growl, roar and continue to try to get out of the cage by clawing at the wooden bars.
El let out a disappointed sigh. "Apparently it can't talk yet."
'Tanjiro, Nezuko... Hurry up and come, this boredom is starting to kill me.' El said in thought.
As if fate answered her wish, soon El felt the presence of another foreign figure entering Tamayo's house even though she was in the basement.
From what El felt, there were two people who entered Tamayo's house. One of them can be confirmed to be human. However, the other was a non-human figure. What El felt, the figure was a demon who was very thirsty for blood but was still suppressed by his desire.
As far as El's understanding of the existence of creatures in the world of kimetsu no yaiba is concerned, the bloodthirsty figure is a demon. But, the owner of the air of existence that El felt was a little similar to Tamayo and Yushiro, on the other hand it also felt different.
"This human's air of existence, could it be Tanjiro? And the Devil's air of existence but it feels a bit strange. Is this Nezuko?" muttered El with a smile on her face.
"Hey, Devil! Do you know any of them?" El asked the new demon again.
"Grr, roar!" But, the demon answered El by growling and roaring.
Feeling that he had almost reached his destination, El was about to get up from the futon. However, because El lay for too long pretending to be paralyzed. Suddenly, his body felt like it had been stung by hundreds of needles.
"Ah, damn... Now I'm really paralyzed. Really?" El said this with a flat tone of voice and expression.
...
The front yard of Tamayo's house, Yushiro was seen with a sour expression. From behind, Yushiro's young boy and young girl followed him, walking towards the entrance of Tamayo's house.
The young boy was of average height with tanned skin. He had disheveled black hair with red tips, slicked back to expose his forehead and wide, dark red eyes with white pupils that appeared lighter around the bottom of the iris. In addition, he also has a scar on the top left of his forehead.
The young boy wore a black and biscay green plaid haori over his all-black Demon slayer uniform. He also wore a pair of distinctive hanafuda earrings with an image of a sun rising over a mountain, similar to what El was wearing.
Right beside the young boy, there was a young girl with fair skin. She had delicate-looking pale pink eyes that seemed lighter around the edges of the iris.
The young girl's body was slender, and sharp nails with a pink base color faded to reddish at the tips.
The young girl's hair was long, black, and wavy. Her hair reached just below her waist, turning a fiery orange color as it passed her elbow, and her wavy, side-swept bangs were drastically to the left.
The young girl wore a light pink kimono with an asanoha pattern, a pale pink lining, secured by a red and white plaid hanhaba obi with orange threaded obijime and green obiage.
Over it, the young girl wore a long dark brown haori that reached her calves, as well as a pair of zōri with pink laces and white tabi socks, wrapped in a thick black piece of material that resembled a kyahan.
The young girl also wore a small pink ribbon on the left side of her head to keep her hair from covering her face, along with a bamboo stick secured around her jaw with a piece of cloth.
"Wow... It turns out there's a big house behind the wall." The young boy said with an amazed expression.
Before entering the house, Yushiro turned around and quickly threatened the young boy. "Hurry up and come here. Listen, don't be rude to the people inside."
Suddenly, Yushiro stepped very quickly in front of the young boy with a cynical expression in his eyes. "I don't care about you guys. But, since that woman insisted, I brought you to this house."
Knock... Knock!
"Please." said Tamayo, inviting them in with a soft tone of voice.
The door opened, revealing Yushiro opening the door with their two guests. Yushiro then responded by greeting the house. "We have returned."
"Welcome." Tamayo welcomed Yushiro and his two guests.
