Chapter 328: The only soul that the Prince of Flies will come to seek personally...

Klein sighed at length, a look of manifest contempt on his face. " Princess Sierra is really an idiot... Making a pact with a demon... "

She scratched her head, blushing again under the insult, unable to protest as the truth of his words . She tried to stand up with dignity to end this humiliating conversation, but her movements were still clumsy. She tripped lamentably and sprawled full length on the ground, right at the exorcist’s feet.

" What do we do now ? " she asked, raising an imploring gaze toward him from the ground.

Klein did not move to help her. On the contrary, he took a step back, his gaze suddenly becoming sharp as a blade. " Well, now, princess, you are going to tell me where Princess Sierra is... "

The young girl blinked, feigning incomprehension. " Huh !? What do you mean ? "

Without another word, Klein drew his sword with lightning speed and delivered a devastating horizontal attack. The blade split the air in a deadly whistle.

Sierra only had time for a superhuman survival reflex, performing a prodigious leap backward to escape decapitation. She landed softly on her feet, all trace of clumsiness having disappeared instantly. For an elf, physically weak it was impossible to have this reaction time. 𝕗𝚛𝚎𝚎𝐰𝗲𝗯𝗻𝚘𝚟𝚎𝗹.𝕔𝐨𝕞

Sierra’s smile widened then, losing all trace of shyness to become an expression of pure predatory malice

" Exactly when did you notice that it was me ? " she asked, her voice having changed to a more melodious tone.

Klein calmly took a cigarette out of his pocket and lit it with a nonchalant gesture, superbly ignoring the threat. He exhaled a puff of gray smoke that slowly dispersed in the air.

" The nauseating smell of your mouth that stinks of sulfur... "

The creature burst into a shrill laugh. Under Klein’s eyes, the elf’s body began to transform. Three black and twisted horns burst from her forehead, tearing her pale skin, while the white sclera of her moon eyes turned to absolute black, leaving only her silver pupils shining with a demonic glow.

" You are quick-witted... As expected from the Mystical Exorcist..."

" Mystical Exorcist ? " repeated Klein.

" Since Konstantine, you are the only soul that the Prince of Flies will come to seek personally... You have caused way too many problems, little human... " she added.

’ It seems that even the demons do not know that Diavolo is alive... ’ thought Kaiser, noting that Shaytan ignored that her true master was none other than the Wizard of Constellations himself.

" Enough talking, Shaytan. Tell me where Sierra is... " he ordered, his hand tightening on the hilt of his sword.

The demonic princess smoothed her white hair, her smile becoming even more cruel.

" She paid her pact... Her soul belongs to me now. And soon, your body will be my new playground ! "

She propelled herself forward, the thorns of her demonic mana bursting from the ground to seal the fate of the exorcist who dared defy Sloth. The real fight for Sierra Del Luna’s soul was only just beginning.

...

Facing Klein, Sierra’s graceful body was now the receptacle of an entity whose mere aura was enough to wither the grass around her feet. The three black horns that adorned her forehead pulsed with a demonic glow.

Kaiser let out a puff of gray smoke before dropping his cigarette butt. His cold blue eyes narrowed, analyzing the distortion of space around the demoness.

" You talk a lot for a parasite that needs the soul of a kid to exist in this world... " he replied in a casual tone, although every muscle in his body was tense, ready to explode.

" Arrogant, just like Konstantine..."

Suddenly, the air became heavy. It was the manifestation of Shaytan’s Sloth, a force that sought to slow the heartbeat and numb the reflexes. Klein felt his limbs weigh tons, but he did not retreat. He forced his aura to circulate in his veins with increased violence to counter the stasis.

< Activation of the skill : Eyes of Predation >

Immediately, bulging veins appeared at the corner of his eyelids. His vision changed radically, perceiving the flows of demonic mana that intertwined with the structure of the domain.

He then saw the true obstacle : a barrier of magic mirrors, invisible to the naked eye, that enveloped Shaytan like a second skin.

Kaiser disappeared in a silver blur.

< Aura Technique : Dash >

He reappeared instantly in front of the demoness, delivering a devastating attack with his katana. The blade split the air with a high-pitched whistle, aiming for Shaytan’s neck. But at the moment of impact, a crystalline shimmer appeared. The blade did not cut the flesh ; it bounced violently, as if it had struck an indestructible steel surface. Even worse, the kinetic energy of his own blow came back full into his chest, sending him flying backward.

Kaiser recovered with a fluid pirouette, his boots plowing the blackened ground.

" Mirror Magic... " he murmured while wiping a trickle of blood that flowed from his lip. " It does not just block, it sends back the force of the impact with amplification. "

Shaytan laughed, a sound that resembled the breaking of thousands of glasses.

" You are quick for a mortal. But my Mirror is an automatic barrier. Any attack, whether of mana or aura, will turn against you even before you have been able to touch my skin. Give up, Klein. Let sloth consume you. "

< Art : Sundering Eclipse >

< Second Movement : Quarter Moon >

The blades began to vibrate, emitting a low-frequency hum . Klein rushed forward again. This time, he did not attack with a single massive blow, but his swords traced dozens of arcs of white and black light in a few seconds.

*CLANG ! CLANG ! CLANG ! CLANG !*

The impacts multiplied against Shaytan’s invisible barrier. With each blow, the mirror shimmered, sending back shockwaves that Kaiser dodged with hip movements calculated to the millimeter.

However, the genius of this technique lay in the aura residues. Each passage of the blade left behind a "echo" sharp suspended in the air

Shaytan, initially confident, saw the space around her become saturated with these stationary blades.

" What is this... ? " she began, losing some of her arrogance.

" Your mirrors have a reaction time, do they not ? " Kaiser launched while continuing his dance. " They react to direct attack vectors. But what happens if the attack comes from everywhere at once, without initial movement ? "

Dozens of invisible blades converged on Shaytan from every blind angle. Shaytan’s mirror barrier went into a frenzy. Shrill cracking sounds rang out as Sierra’s magic, pushed to its limits by demonic influence, tried to reflect everything.

*BOOM !*

An explosion of pure mana shook the plain. Shaytan’s barrier shattered into pieces, and the demoness was thrown to the ground, her left shoulder lacerated by a trail of aura. Black and viscous blood, smoking like acid, flowed onto her white dress.
