My Demon System : From Outcast To Hunter

"Damn that man! Who is he, really? A demon from hell itself? He kills anyone who dares stand in his way! He's…"

Before one of Prince Kairon's soldiers could finish cursing Itaru, breath was snatched from his lungs.

His body collapsed lifelessly to the ground—heartless. Itaru had crushed his heart and then tossed it to the dirt, stomping on it with his foot.

"This feels amazing… I… I want… I want more,"

Endo, stunned by Itaru's words and the bizarre expression twisting his face, realized—this man wasn't normal. He was a curse in human form. A lunatic.

[Devil's Blood +10]

[Your Devil's Blood has increased by 10]

[Your Devil's Blood has increased by 10]

Each time he killed a soldier, those messages flashed before his eyes. A torrent of energy flowed into his heart, a wave of euphoria washed over his mind. It was like being in another world. Every cell in his body screamed—demanding more.

The people of the region had witnessed bloodshed before, especially when Prince Kairon invaded their district. But never like this—this level of brutality, the sheer savagery of how he tore his enemies apart—it exceeded their worst nightmares.

"Damn you! Stand still for once!"

Each stab, each fallen soldier happened in a second—sometimes less. Endo could barely catch the movement in Itaru's pupils before he lost yet another man.

He couldn't predict when or where Itaru would strike. It was like the madman was toying with them.

'Is he avoiding me because he sensed my strength?'

Endo thought, concern etched into his face. When he turned to look, he realized half his men had already fallen.

"You filthy freak! I'll kill you!"

Itaru placed his claws around Endo's neck. Endo's once-white suit was now soaked in his own black blood. Itaru licked his claw slowly, locking eyes with Endo, who looked like a volcano ready to erupt.

"Don't borrow my words, Endo. Clean your mess first—then I'll make sure no one sees your execution."

Itaru state the added: 

" I want no soldier witnessing your beheading. I want to preserve your dignity,"

For a moment, Endo felt the weight of pressure on his shoulders as Itaru finished speaking. The moment he pulled out his dagger and lunged at Itaru, it was all for nothing—he struck only empty air.

"Aaah… aaah…"

"Commander…"

"Damn that bastard!"

Itaru made sure his enemies died in agony—their screams filled the air. Serum's tears flowed uncontrollably. Since the death of her father, the 25th Demon King, she hadn't seen such bloodlust. Especially not from someone like Itaru.

Yes, those were tears of joy.

"Whatever dwells inside him… Itaru will become a legend."

In the Demon Realm, killing was a duty. It was how demons earned recognition. The stronger or closer the victim was, the more fame you gained. Bloodshed fed your status.

This world belonged to the strongest, the cruelest—the merciless. You either ruled or died. There was no middle ground. No other path.

"Only two left. Where will you run now?"

Just as Itaru pierced the heart of a fleeing soldier, he suddenly felt something—his arm fell to the ground. That bastard Endo had severed it.

And yet, Itaru didn't even flinch. He kept chasing the fleeing soldier, as if Endo didn't exist—like his mind was fixed on a single purpose.

Three jumps later, a devastating kick sent the soldier crashing into four thick walls, which shattered into pieces. The last of Endo's men charged at Itaru.

"YAAAAAARGH—!"

His cry of excitement turned into a final scream as he fell.

"All my soldiers were elite demons. You can't just slaughter them before my eyes like this! I— I won't let you go unpunished!"

Endo moved, his eyes surveying the bloody scene, the stench of gore, the scattered heads of his men. He clenched his rage.

[Congratulations! Level 1 of Devil's Blood has been completed.]

[Level 2 unlocked.]

[Devil's Blood: 100/500]

[You have gained the skill: Demon Mode – Phase One. This skill allows you to transform into a demon with half the power and abilities of those you've slain. Your physical attributes will also increase by 40%.]

This was what Itaru wanted—to experience Demon Mode. It was what thrilled him. What made adrenaline flood his every nerve. He loved this system—at least so far.

[Player, do you wish to activate Demon Mode? You may use it for three days each week.]

Everyone stared in awe. Endo's eyes widened as the size of his dagger quadrupled—it wasn't a hallucination.

"I just sliced him in two. This is his blood!"

Endo muttered as he wiped the blood off his shoulder and parts of his face. The dark clouds in the Demon Realm's sky parted, revealing a crimson sky above.

"I think… a royal demon has been born. My God… I'm truly lucky to witness this. I'm so happy,"

Daid spoke slowly. Even the dust in the air froze in midair.

The arm Itaru had lost grew back—stronger than before. He didn't descend from the sky. He simply stood before Endo, grinning, revealing his fangs.

His skin now blackened, short horns—about seven centimeters—grew from his head, pulsing waves of energy every ten seconds. Each time, Endo felt a chill rattle his skull.

Every time Endo raised his dagger and cut a piece of Itaru, the boy regenerated—stronger than before.

"Heeey, you cursed freak—DIE DIE DIE!"

His dagger glowed, his muscles swelled—he was finally taking this fight seriously.

Their movements, their rapid dashes across the buildings—each structure collapsed under their weight and speed—it was unreal, inhuman.

'I led the Demon Scouting Corps for two centuries, and never lost a man. I protected them all.'

Endo thought. Now he wanted only one thing—to kill this monster. He didn't know how Itaru changed so drastically, or how he got this strong, but damn him a thousand times.

Several windows appeared before Itaru, displaying weapons he'd never even heard of.

This… this was only Phase One. What would the higher stages look like?

"I'll rip you apart with my bare hands. I'll savor it. I'll kill you—and your prince too,"

Itaru laughed. Who needed a weapon to kill this soldier? This would be fun.
