Octavio

"I was very lucky to meet Demon Slayers in this remote village, Muzan-sama must be very happy to know the deaths of more Demon Slayers… Hehehehe…"

The skinny Demon giggled, he imagined getting more blood from Kibutsuji Muzan and he would become stronger.

*swoosh*

Rio's figure appeared in front of the Demon, his sword swung horizontally which instantly cut off the Demon's head before it could respond.

"Have you never heard of villains dying from talking too much?"

Glancing at the headless body, Rio waved the sword to the side preparing to insert the sword into the scabbard.

*Poof*

White smoke suddenly appeared and the headless Demon turned into a block of wood.

Seeing this strange scene, Rio's pupils contracted, without hesitation he swung the sword backwards.

*Ting*

The sound of metal clashing was heard along with sparks between the sword and the 5 meter long fingernails.

"Tsk, you were able to fend off my sneak attack."

"How sharp are your instincts!"

It was none other than the Demon that Rio had just beheaded.

Rio didn't comment on the Demon's comment, he swung his sword at the Demon's barrage.

*Ting Ting Ting*

The Demon didn't lose either, with hooves no weaker than metal and a sharp weapon, it tried to fend off Rio's attack.

But either due to having no experience in actual combat or never having fought a strong foe, the Demon couldn't match Rio's movements and there were many cuts on his body, but because of the Demon's lack of immortality, his wounds healed quickly.

"Why are you so strong! The Demon Slayers I met were not as strong as you!" The Demon shouted in annoyance.

"I'm not the strong one, they're the weak one." For the first time, Rio responded.

"You bastard!" The Demon felt humiliated hearing this.

"Thunder Breathing, Ichi no kata: Hekireki Issen (First Form: Thunderclap and Flash)."

Rio slashed really fast without giving the Demon any time to dodge.

*Swoosh*

For the second time the Demon's head was severed by Rio.

Unlike before, Rio didn't lower his guard, he didn't think the Demon was dead.

He guessed that the Demon possessed the Demon Blood Art that replaced his death with a wooden block. That's why Rio was still alert despite decapitating the Demon, his eyes glancing in all directions so as not to be hit by a sneak attack.

*Poof*

As Rio expected, white smoke reappeared on the Demon's body and turned into a block of wood.

"Do not appear?"

After a while of waiting, but the Demon didn't appear, Rio frowned.

"Escape?"

Rio was lying on the ground, pressing his ear to the ground, he heard the sound of footsteps slowly drifting away.

"There."

After determining the direction the Demon was going, Rio inhaled a large amount of oxygen into his lungs.

"Total Concentration Breathing."

Then Rio ran at an inhuman speed.

The skinny Demon ran away from Rio without looking back.

"What the hell is that Demon Slayer, why is he so different from the other Mizunoto rank Demon Slayers."

"Less than 5 minutes, I've been beheaded 2 times! If it weren't for the Kawarimi No Jutsu (Body Replacement Technique) I got from the Beginner's Pack, I would be dead by now."

The Demon saw Rio's rank Demon Slayer engraved on the uniform, he had killed 4 Mizunoto rank Demon Slayers, that's why he looked down on Mizunoto rank Demon Slayer.

But he didn't expect to meet such a powerful Mizunoto rank Demon Slayer.

"Could it be that that person is also a Player?"

A possibility appeared in the Demon's mind.

"If that's true, I really had the misfortune of meeting a user on the Demon Slayer Corps' side."

There were only 15 players on the Demon Slayer Corps' side, and only 3 days after the new Quest was released the Demon didn't expect his luck to be so bad.

"Ichi no kata: Hekireki Issen (First Form: Thunderclap and Flash)."

The Demon jumped with all its might to the side dodging the blade that nearly cut off its head.

"Almost."

There was cold sweat on the Demon's forehead, if he was even a second late, the remaining use of Kawarimi No Jutsu would be used up.

"Hey you, you're a player, right?" Demon asked while rubbing his forehead.

Rio gave no response, he looked at the Demon with an indifferent expression.

Seeing Rio silent, the Demon mistook that for an answer.

"Can you let me go this time? As fellow humans from earth, shouldn't we help each other?"

"Oh right, my name is Octavio from Brazil. What's your name?"

The Demon named Octavio judged the youth in front of him to be 16 or 17 years old. At this age, many young men are still naive and innocent, according to him the young man in front of him can be persuaded.

"I don't need to tell my name to people who are about to die."

After saying that, Rio using <Reduced Earth> appeared before Octavio and swung his sword vertically splitting Octavio's body into two pieces.

"What---"

Octavio did not expect this young man to be so cruel, he was careless and died once again.

*Poof*

Octavio's body that was split in half became white smoke and a block of wood once again appeared.

"Damn it, what are you doing bastard!"

Octavio did not expect the young man in front of him to be so decisive, the young man only said a few sentences and immediately attacked him.

He could only use the Kawarimi No Jutsu three times, now Octavio has no way of saving lives anymore.

"I will kill you until you can no longer live."

Rio had no intention of having a chat, after declaring that, he ran to attack Octavio.

"Shit Shit Shit, this guy is a psychopath!"

Even though Octavio had become a Demon, his outward appearance was still human. To kill a human without changing his expression, he could only describe that person as a psychopath.

*Ting Ting Ting*

With no other choice, Octavio was forced to serve Rio. He didn't want to die, especially when he already had half-finished immortality.

As for why Octavio calls Demon immortality half-finished, because Demons will still die if exposed to sunlight and their heads beheaded by Nichirin's Sword.

Aside from those two weaknesses, the immortality that Demons have is quite tempting. Does not age, does not contract disease, the stronger the more humans are eaten, and can live forever. How can people not be tempted?

"Don't daydream in the middle of a fight."

Rio watched Octavio think of something else, taking advantage of this gap, his sword shot into Octavio's neck.

"Thunder Breathing, Ichi no kata: Hekireki Issen (First Form: Thunderclap and Flash)."

"Eh...?"

Once Octavio was awakened by Rio's reminder, it was already too late.

In the air, Octavio saw his headless body slowly turning to ashes.

"I die?"

Filled with anger and regret, Octavio looked at Rio with a look of hatred before his head also turned to ashes.

"So only three times..."

Seeing that Octavio had turned to ashes which was the condition of the Demon's death, Rio now confirmed Octavio had really died.

"Hmmm...? Is that it?"

Inserting the Nichirin Sword into the scabbard, Rio was startled by red ripples appearing at the location of Octavio's body earlier.
