"Boom————!"
In the explosive sound, the burning flames gradually expanded, becoming more and more vigorous.
"Ahhhhhh————!"
The Meyer sisters, continuously engulfed by the increasingly powerful flames, kept screaming in agony, rolling on the ground in an attempt to extinguish the fire.
However, it wasn't so easy to put out.
This was the power brought by Rozen's Mystic Eyes. As long as Rozen's gaze remained fixed on the target, they couldn't escape the fate of being burned by the flames.
Rozen coldly stared with his pair of fiery red Mystic Eyes, disregarding the sisters' screams, steadily increasing the output of his magic, causing the power of his Mystic Eyes to rise linearly, burning the witch sisters alive.
Pitiful as they were, these witch sisters were previously cruel and heartless, either torturing their enemies or continuously killing. Today, they finally received their comeuppance from Rozen.
This was truly an eye for an eye.
After all, Rozen intentionally maintained the power of his Mystic Eyes at a level that wouldn't be fatal.
It's worth noting that Rozen's Mystic Eyes weren't just burning eyes but exploding eyes.
In other words, the burning flames were just a side effect of these Mystic Eyes.
The true power of these Mystic Eyes lay in instantly destroying the target with the fierce and volatile flames.
If Rozen exerted full force, even Vatler's luxurious cruise ship would be instantly shattered, let alone two witches who only knew how to command guardians and grimoires.
Therefore, Rozen sought retribution, an eye for an eye, not seeking revenge but merely waiting for the right moment to use the power of his Mystic Eyes to slowly burn these cruel and heartless witch sisters.
Observing from the sidelines, La Folia also watched coldly.
If it were Yukina, Nagisa, or Avrora, among others, witnessing this scene beside Rozen, they would surely feel unable to bear it, right?
This wasn't about being saintly or naive; it was just that no one, regardless of who they were, would want to see the people around them tormenting others, let alone remain indifferent to their screams of agony.
It was precisely because of this that when dealing with the Apostle, Rozen directly used the power of the Crimson Wing Formation to erase his existence, allowing him to die quickly and painlessly.
But La Folia was different.
As the princess of Aldegyr, La Folia wasn't a bad person, but she certainly wasn't a good person either. She understood what it meant for someone to deserve punishment and who could be forgiven. Some people should be valued and helped, while others were pests who needed to be punished and even judged in order to maintain the order of the country and the world.
And the Meyer sisters were just such pests.
If it were La Folia herself, she might not directly take the lives of the Meyer sisters but would instead capture them and give them the punishment they deserved.
However, even if these sisters were tortured and killed in front of her, La Folia would not frown because they deserved it.
In view of this, La Folia didn't think Rozen torturing the Meyer sisters was cruel, nor did she find it satisfying. She just watched coldly, quietly witnessing the final fate of these cruel sisters.
To have the end witnessed by a princess of another country was also La Folia's only mercy to these witch sisters.
As for Rozen, he didn't torture the Meyer sisters for pleasure either; he just thought it was too cheap for them to die so easily.
In this situation, Rozen continued to increase the power of his Mystic Eyes, steadily burning the sisters, giving them the punishment they deserved.
Gradually, the screams of the Meyer sisters became hoarse, their clothes completely burned away, leaving only their alluring bodies exposed in front of Rozen.
However, Rozen paid no attention to these tempting bodies, remaining indifferent, coldly staring at the two, causing the flames on them to persist without extinguishing.
"Thud..."
"Thud..."
With a muffled sound, the Meyer sisters each fell to the ground, their consciousness mostly deprived by the burning pain.
Thanks to this, the guardians they commanded also disappeared, and even their grimoires fell to the ground.
In the current situation where the witch, who possesses the invincible guardian, has fallen, the guardian, theoretically unbeatable as it may be, is now useless.
This is one of the methods to defeat No. 193, to directly attack the owner of the guardian, whom the guardian cannot reach at the speed of the holder, so that when the owner falls, even the strongest guardian will disappear on the spot.
Realizing their defeat and still being burned by flames, the sisters Emma and Octavia Meyer convulse their bodies and plead towards Rozen.
"Please... please spare me..."
"I... I'm willing to do anything... please... have mercy..."
These cruel and bloodthirsty witch sisters finally beg for mercy.
But Rozen ignores them completely.
*Swish!*
Accompanied by a blurry spatial fluctuation, the Grimoire named No. 193 disappears from its original location and appears in Rozen's hands.
"As a spoils of war, this isn't too bad."
Rozen calmly puts away the Grimoire.
The power of the Harmony of Primordials is actually very strong, involving causality, and Rozen cannot ignore its existence.
Having such a Grimoire as a spoils of war is indeed quite good.
Of course...
"There's another one here."
La Folia Rihavein disregards Emma and Octavia, and gazes towards the location of No. 539.
That Grimoire is equally powerful. Its ability to manipulate space affects the entire Itogami Island, indicating how strong its power is.
However, as Rozen has said before, to touch that Grimoire, it depends on whether others are willing to let him
The "others" mentioned here are definitely not Emma and Octavia.
To Rozen, the sisters are just minor characters. Even if they obtain the power of the Grimoire, they would at best be comparable to the old generation of vampires and would not be worth his attention.
There must be another formidable enemy who can make Rozen say such things.
"The first team, Philosophy, to which Emma and Octavia belong, manipulates causality and ontology. Physical magic that controls space is not within their specialty."
Rozen says so.
In other words, with Emma and Octavia's abilities, it's impossible for them to activate the Grimoire No. 539.
A Grimoire cannot be used casually. If one does not have the corresponding abilities and qualifications, it will only cause the Grimoire to go out of control, run amok, or even be devoured by the power of the Grimoire.
With this in mind, Emma and Octavia must not be the users of No. 539.
"The real user of this Grimoire is someone else."
Rozen's gaze is firmly fixed on the floating Grimoire's front space.
"..."
La Folia seems to have also noticed something and stares over.
So, both of them see it.
In front of the Grimoire, there is a peculiar distortion of space different from the entire Itogami Island.
"So you've noticed?"
A voice, both relieved and helpless, comes from the shaking space.
"But, this level of deception is certainly impossible to deceive you."
As the voice falls, the flickering space cracks open.
Yes, it cracks open.
Just like a crack appearing in space, a girl slowly walks out from it.
She has long green hair.
She has eyes like emeralds.
Full of wildness, yet with a hint of mystery.
"We finally meet, Divine Child."
The girl suddenly smiles.
The surrounding atmosphere is instantly suppressed.
