After that, Rozen and La Folia didn't manage to have a smooth conversation for a long time.
The atmosphere between them had completely changed, carrying a hint of ambiguity and a tingling sourness, sweet and sour, making the surrounding pedestrians feel embarrassed to continue watching, so they could only retreat.
In such a situation, the waiters at the outdoor restaurant delivered the meals ordered by the two with awkward expressions, and secretly gave Rozen a thumbs-up, making Rozen laugh dryly.
The two began to have their meal.
However, they didn't remain silent the whole time.
"Actually, before today, Sayaka and I had encountered random spatial displacement phenomena."
La Folia mentioned this very suddenly.
"You've encountered it before?"
Rozen's spirits lifted, finally taking it seriously as he looked at La Folia.
"I think it's a phenomenon that reacts to extraordinary magical and spiritual power in individuals. The more outstanding someone's magical and spiritual power is, the easier it is to trigger this phenomenon. So Sayaka and I encountered it yesterday."
La Folia said so, making Rozen somewhat enlightened.
If that's the case, then it would explain why La Folia and Sayaka encountered this phenomenon before today.
Sayaka, as a Warlord Dominion's Shamanic War Dancer, must have considerable spiritual power, not much inferior to Rozen's.
As for La Folia, being the daughter of the Aldegyr royal family and a naturally high-level spirit medium, her spiritual power can even rival that of third-generation vampire elders and second-generation vampire royals, not to mention she's also an spirit summoner, capable of summoning powerful spirits with massive spiritual power, which is no less than having a beast vassal for a vampire.
With such two individuals together, if the random spatial displacement phenomenon is triggered by the magnitude of magical and spiritual power, then it's understandable that they encountered this phenomenon yesterday.
In contrast, Rozen, although he possesses boundless magical power as a Primogenitor, it is firmly sealed within him. Without lifting the seal, this magical power will not be detected, and he did not trigger this phenomenon until just now when he was with La Folia.
"Because of this incident, I did a little investigation."
Saying that, La Folia looked at Rozen.
"Do you know about the 'Library'?"
The sudden mention of the name by La Folia made Rozen's eyes widen.
"The Library."
It is a world-renowned criminal organization, whose full name is the Library of Criminal Organization (LCO), commonly known as the 'Library', or simply 'LCO'.
LCO is a huge criminal organization composed only of high-ranking mages and witches, with a membership of thousands. Its total combat power is enough to rival that of a nation. Compared to it, even the Black Death Emperor Front, which advocates Beastmen supremacy, is weaker by far.
Because, within LCO, there are not only high-ranking mages and witches, but also numerous grimoires collected from all over the world.
It has been mentioned before that due to the preciousness of grimoires, many mages and witches collect them from all over the world and strictly classify them according to their purposes, either sealing them or handing them over to those capable of manipulating them, continuing the wisdom left behind from ancient times to the present.
However, there are also some mages and witches who are not interested in developing grimoires or protecting world peace, but only seek to satisfy their own curiosity and desires. They gather together, regardless of means, collecting grimoires from all over the world, acting recklessly, selfishly, and becoming a criminal research group with criminal characteristics.
And LCO is exactly such a group of reckless and self-centered grimoire researchers, with criminal organization characteristics from its inception, but has collected numerous grimoires from all over the world, hence the nickname "Library".
This establishes the danger of LCO on a global scale.
After all, you have to know, just one powerful grimoire going out of control can destroy one or two cities, but within LCO, there are many such books. It's easy to imagine how high the overall organization's combat power is.
Rozen knows about this organization to some extent.
The reason is simple.
"It is said that ten years ago, Itogami Island once welcomed a witch from LCO. That witch used an extremely powerful grimoire on the island, causing great damage and loss to the entire Itogami Island. In the end, your sister, the one called the 'Witch of the Void,' intervened and defeated the opponent, confiscating the grimoire, thereby saving Itogami Island, right?"
La Folia mentioned this incident.
"..."
Rozen fell silent immediately.
Of course, Rozen knew about this incident.
At that time, Rozen was already five years old, while Natsuki was still in high school. The siblings grew up together, relying on each other. Such a major event naturally couldn't escape Rozen's knowledge.
Moreover, Rozen was somewhat involved in that incident.
Even though Natsuki went to deal with it when it happened, Rozen, being too young at the time, was not taken along. But for Rozen, that event at the time also had an impact on him.
So, La Folia mentioning LCO made Rozen's mood quite complicated.
But bringing up this matter now is pointless.
"You mentioned the name of LCO, is it related to the recent anomalies on Itogami Island?"
Rozen asked in a low voice.
La Folia neither confirmed nor denied it, just saying this.
"Not long ago, Itogami Island was invaded by criminals."
La Folia suddenly revealed this news.
"The attackers were the Meyer sisters, known as a handful of belligerent elements within LCO, belonging to the first team, 'Philosophy,' known as the 'Witches of Ashdown.'"
Witches of Ashdown—
This name is equally famous.
They are a pair of witch sisters.
The elder sister's name is Emma Meyer, known as the "Witch of Darkness."
The younger sister's name is Octavia Meyer, known as the "Witch of Crimson."
Because the two sisters often act together and are both witches, people refer to them collectively as the Meyer sisters.
In the past, the two sisters boldly conducted extremely dangerous magical rituals in Ashdown, within the Northern Sea Empire, ultimately causing a huge disaster, leading to the disappearance of an entire province and a vast forest, and they became internationally renowned first-class magical criminals.
In the incident ten years ago, among the witches who caused unprecedented damage on Itogami Island, these sisters were also involved.
In other words, the Meyer sisters were also the culprits who caused great damage on Itogami Island ten years ago.
However, after the leader of the witches was defeated and arrested by Natsuki, these sisters fled in fear of Natsuki and eventually escaped.
If it is indeed these witch sisters, it is indeed possible for them to invade Itogami Island again.
And with their power, it's unlikely that the special district security forces of Artificial Island Management Cooperative can deal with them. It's only natural for them to invade.
"It was indeed the Meyer sisters who invaded the Itogami City last night."
La Folia smiled slightly at Rozen.
"In that case, do you think they are unrelated to the strange spatial phenomena that occurred on Itogami Island?"
Can they?
Of course not.
"Because of the incident ten years ago, the Meyer sisters are quite hostile to your sister," La Folia said with a meaningful smile, "What are you going to do?"
Does that need to be said?
Thinking of the inability to contact Natsuki today, Rozen's eyes suddenly turned cold.
His gaze then turned in the direction of the Keystone Gate.
