Rencarnation Room {Other Story line}

El's serious gaze became a little softer. "My judgment does not seem to be wrong this time. I also expected you to ask about my true identity."

"However, I'm sorry. I can't tell you about that. One thing is for sure, I guarantee that your life will not be involved in any conflicts. Your job will only be to watch over my fortune and a family from here." explained El, with a cold tone of voice, full of emphasis and seriousness in her words.

Kirai stared at El's eyes which looked very serious. After a while, Kirai nodded her head slowly. "Young master seems very serious. However, more importantly, I like living in luxury."

"Meaning you agree?" El said so with a cold tone of voice. Then, raised his right hand and stuck it out. "It's a pleasure working with you, my wife."

Deg! Deg! Deg!

Kirai's heartbeat suddenly skipped a beat as soon as she heard the word wife come out of El's mouth. Not only that, Kirai's beautiful face became even more flushed in the process.

Unable to bear the embarrassment, Kirai immediately turned her face to the right. Both hands raised and waved quickly, Kirai fanned her hot face.

"Uwa! Wake up Kirai, this is just a contract marriage! You are going to be his wife, but it is written on paper." muttered Kirai very quietly, hoping that El did not hear her.

However, Kirai's wish could never come true because El could hear Kirai's muttering. In his heart, El felt a little guilty even though Kirai was allowed to use his property. However, in the end, El only used her.

Inwardly, El muttered with a sad look when Kirai turned his face away. 'I'm sorry, Kirai. I asked you to do this because I will not be able to always take care of my family in this world.'

...

Ever since that day. The day El and Kirai agreed to a contract marriage, Kirai's days were filled with luxuries that El gave freely.

Although, Kirai was given a condition. That was to keep an eye on the circumstances of a middle-class family that suddenly became billionaires mysteriously.

At first, Kirai was very curious and really wanted to ask about it. But, considering the contract they agreed together, Kirai undid her intention.

Kirai monitored the situation of a family that El was referring to by hiring the services of a person, secretly spying on their every activity. Then, detailing the report and sending it to Kirai via email message, as the hiring party.

After receiving the detailed report data, Kirai immediately gave the report to El. 'Hmm, so that's it. They invested the money I gave them to build a shop.' El thought.

The days passed quickly like a rolling wheel. It had been 9 days since El had vacationed in his world. At exactly midnight, El would return to the Rencarnation Room.

This afternoon was sunny with a little cloudy. Some birds flew in the sky of El's house like they were singing a song.

Currently, El was accompanied by Kirai in their luxurious house. El was sitting on the balcony seat of the house, while flipping through the report paper in his hand.

Kirai was watching El who was currently flipping through, reading every word in the report carefully. When reading the contents of the report letter given, El's eyes looked very deep and mixed with sadness.

An expression of astonishment was etched on Kirai's beautiful face. Kirai tilted her head slightly to the right. Actually, Kirai was still very curious as to what that family had to do with El.

Recalling the contents of the agreement to become a contract wife, Kirai abandoned her initial intention to ask something.

Not long after, El finished reading the report Kirai gave him. El placed the report papers on the table in front of his. "My wife, you did a good job." El said in a cold tone of voice.

Kirai's face flushed red, heartbeat pounding so loudly it could be heard. Immediately, Kirai controlled herself from the emotional turmoil of happiness. Even so, the corners of her mouth could not help but smile.

Taking a deep breath, Kirai exhaled through her mouth. For a moment, Kirai regained her composure. "No problem, it is my duty."

El smiled at Kirai's reply and, then said: "Ah, that's right. Later tonight I will be away on business, I don't know how long it will take, so don't contact me or even look for me."

"I put the ATM card, house key and Pagini Huayra car key in the safe along with a note of the password. You have memorized the safe password, right?" asked El.

Kirai's eyes became serious at El's words. "Yes, I already know the safe password. But, should I take you to the airport?"

El leaned his back on the chair and closed her eyes. "No need. Forget about the formalities between us. Our relationship is now husband and wife, even if it's only written on paper. To prevent the suspicion of many, please do not be too formal."

Kirai smiled happily when she heard that. "Okay, I understand my husband."

***

The time of day passed quickly. In his dark room, El was standing and wearing the white trench coat he had bought this afternoon while shopping with Kirai at a clothing store.

As soon as he put his right hand on the sleeve of the trench coat, it fluttered slightly even without being blown by the wind.

Suddenly, a system notification hologram screen appeared before him.

Ding!

[Beyonder with serial number 120,000 has spent 1 day in his home world. The system will return you to the Rencarnation room]

Instantly, El disappeared from her home world without leaving a trace. Not long after, the door to the room opened. Apparently, Kirai opened the door and entered El's room without knocking because she forgot.

Kirai thought that El was in a hurry to leave for some important business. "Husband, do you really not want me to take you- Eh?" Upon entering the room, Kirai did not find her husband in the room. "He left already? But which way?"

Instantly, Kirai was silent and lost in reverie. "What a mysterious man." muttered the beautiful woman staring at the window of the room not far from her, with a look full of complexity.

***

El was in a room, where he was undergoing a mission evaluation. As soon as he put his right hand into the pocket of his trench coat, El took out a black box that was the size of his hand. The black box had question mark ornaments on each surface.

This black box was an item El obtained from his first mission evaluation. To be precise, when completing the secret mission.

"System, open the random item box!" El said that with his voice slightly echoing in the silence of the dark room.

Suddenly, the box shattered and became a ball of light that illuminated the dark evaluation room. In the next second, the ball of light in El's hand began to lengthen, 60 cm long with a slight curve to its body.

As the light that wrapped the item in El's hand began to fade, El seemed to recognize the item he had obtained.

Ding!

A system notification appeared, explaining what kind of item El had just obtained.

________

Standard Nicirin

Level: Black

Type : Standard Katana

Description :

This sword forged with Scarlet Crimson Iron Sand (Shōjōhi Satetsu) and Red Ore (Shōjōhi Kōseki) is powerful to kill creatures that are weak to sunlight, if their necks are cut.

_______

In El's hand, there was a katana with a black sheath of a handle and tsuba. Everything was jet black in color. "Nicirin? Isn't this the sword used by the Demon Slayer Corps in the anime series Kimetsu no yaiba?"

Just like in the description. In the Kimetsu no yaiba anime series, the main raw materials for making Nichirin were Scarlet crimson iron sand and red ore.

Both materials have been continuously absorbing sunlight. By decapitating demons using the Nichirin Sword, it can permanently kill them. Once their neck bones are sliced by the weapon, their heads and bodies crumble into ashes in the same way as when exposed to sunlight.

However, despite their sunlight-absorbing properties, Nichirin Swords were less effective when used to cut off other parts of a demon's body, so decapitation became the only viable option for Demon Slayers.
