Cap.5

As time passed, the influence of Muzan Kibutsuji extended from the human world to the supernatural world; the hunting of the onis generated by Muzan at first alarmed some supernatural forces, but not enough to take any action.

Fugaku promptly developed a countermeasure to this problem, as it was now possible to "pick up" food in arrests around Japan.

It is an honorable end for dishonest people. With these measures, the attacks decreased but did not stop.

Muzan was going to inspect one of these arrests, he was looking for possible onis candidates at these locations.

Entering the city, Muzan put on a hood and mingled with the crowd and walked towards the penitentiary where fugaku warned that there was someone with potential.

Entering the courtyard muzan observed that there was a young man beating his "colleagues" in the room, he was a young man with white hair and he used some martial style.

Muzan walked to him when he saw that the fight was over, "boy, what's your name ", the boy turned his head towards muzan and began to watch him.

"My name is Garou, who are you?"

"Me? , I am the progenitor of all a onis - Muzan Kibutsuji, if I may ask the question, were you using any martial art?"

Garou hesitated to answer but said, "the name of my martial art is called water stream rock smashing fist, this martial art was taught by my master Bang.

Muzan smiled mischievously and asked, "why are you here? , you seem very honored to me for a place like that.

Garou made a strange expression, a mixture of anger and sadness, "someone poisoned my entire dojo, and I killed the guilty with my own hands.

Muzan's smile widened and with a blow he emptied garou's chest and injected his blood, within seconds Garou began to transform.

Before Garou even woke up, Muzan erased his memories, unfortunately garou was too kind to keep him aware of his human life.

Garou opened his eyes and observed muzan, he processed the information and quickly knelt down, Muzan with a glimmer of satisfaction in his eyes quickly etched into his eyes the kanji of upper moon 3.

Muzan soon gave his order, "go hunting and become stronger, Garou upper moon 3."

Garou stood up and said, "I will fulfill your Muzan-sama wish, "and left at a much faster speed than most of the newly formed onis.

Muzan outlined a proud smile, 'I have fulfilled all my initial goals of this era, only lack the upper moon 2, but my chosen one will only be born in the XIX century.

'Well, what remains is to develop my personal skills, so first I will train to replicate nakimi's kekkijutsu, and I need a meeting point with high-ranking onis, nothing more useful than infinity castle.'

Nakimi used her biwa as a medium for her art of the blood demon, as she was required to honk the instrument using bachi to play it. As a demon, it is possible that his biwa and bachi are made of his flesh and blood, similar to other tools and weapons used by demons.

With this in mind Muzan cut off his arm which soon fell to the ground, while another arm was already growing because of his regeneration, Muzan molded the flesh of his arm ripped off to form a flute.

Keeping in mind the concepts of space-time, Muzan put the flute in his mouth and started playing it, as a beautiful melody spread, the environment began to change, until it became an infinite space with traditional Japanese rooms.

Muzan smiled with his deed, with this the onis had a secure base, which could not be invaded by most of the beings of this world.

With his blood connection to each of the onis, Muzan could feel them and transport them through time space to their location, with that in mind he summoned tokugawa, the upper moon 5.

Tokugawa was somewhat surprised, but when he saw his Lord he soon recomposed himself, "your orders, Muzan-sama ".

Muzan walked closer to tokugawa and said, "I need to know the current situation of the youkais ".

Tokugawa promptly replied, "the west youkai faction, also known as the Kyoto youkai faction, are a group of youkais that are led by Yasaka, and the east youkai faction, also known as the kanto youkai faction, are another group of youkais led by Nurarihyon."

Muzan pondered a little and asked, "which one is in a more fragile state for us to take on?"

"Muzan-sama, currently the weakest faction and the eastern faction led by Nurarihyon"

Muzan thought for a moment and looked for someone with his blood connection and pulled him to this place through time space.

Garou, unlike tokugawa, was not surprised; he just silently waited for his orders.

"Garou, I want you to go to the youkai faction of the east and kill their leader, Nurarihyon."

With excited eyes for the good battle to come, he readily accepted his mission.

and spent a few days... , one night in the complex of the youkai nurarihyon clan, a battle takes place between their leader and the oni known as Garou.

Garou was having fun with the battle, the harder the battle, more Garou's battle spirit increases, Garou's fists begin to gain a blue tone and his movements begin to become more fluid.

Nurarihyon was getting slower, the wounds on his body were accumulating, while Garou got faster and faster, more and more flexible, and when he suffered from a wound, his healing factor quickly left him ready for battle again.

Nurarihyon was struggling to make his body respond before Garou's attacks hit him, and in a moment of carelessness Nurarihyon's defense was open.

In this breach garou delivered a string of blows with his martial art, the water stream rock smashing fist.

Nurarihyon was sent at high speed until it collided with a tree; by its current state, several internal organs were crushed.

Nurarihyon was beginning to lose his spark of life, but even so he remained with his burning will and used all his strength to deliver a decisive blow.

"Do you think you can defeat me only on the basis of physical strength? , I'll show you the technique by which my clan is famous.

"Shin meikyo shisui"is a technique that frightens the enemy with an overwhelming amount of "fear", making the enemy unable to feel Nurarihyon's presence.

Nurarihyon now without presence moves towards garou planning to end the fight with a final blow.

As Nurarihyon approaches, garou whispers "blood demon art - hakai satsu" and strikes a blow that sends a shock wave towards Nurarihyon.

Nurarihyon is sent flying to one of the houses of the complex which is destroyed in the crash, when the dust begins to subside.

"How? , you shouldn't have been able to feel me"

Garou gave a simple answer, "fighting spirit". When these words fell, nurarihyon accepted his defeat and began to close his eyes never to wake up again.

Muzan who watched this along with tokugawa ordered, "Tokugawa, I need you to suppress the information about this night is to take command of the eastern faction.

Tokugawa nodded and said "shall be done as Lord muzan commands".

And so 400 years passed...

-19th century.
