"I didn't come here to listen to your useless chatter," Rozen spoke bluntly, no longer mincing words.
"If you brought me here just for this, then I think we have no need to continue our conversation."
This was Rozen's ultimatum.
Endo Yukari stopped in her tracks.
"It seems you are very dissatisfied with the Lion King Agency's surveillance," Endo Yukari remarked calmly, neither disheartened nor feeling defeated.
In truth, Endo Yukari just wanted Rozen to accept monitoring.
There was no way around it. Rozen was no fool; the Lion King Agency wasn't confident they could monitor him without him noticing.
And since there was no way to monitor Rozen without him noticing, as Rozen said, if he truly wanted to hide, the Lion King Agency couldn't possibly keep track of him.
However, as a national espionage agency, the Lion King Agency couldn't allow Rozen, a potential explosive threat, to roam freely.
Therefore, in the end, the Lion King Agency had to persuade Rozen to voluntarily accept monitoring.
"I don't think it's a bad thing," Endo Yukari said confidently. "You don't want the monster sealed inside you to come out and harm the people around you, do you?"
So, accepting monitoring from the Lion King Agency meant that if there were any flaws in the seal, there would be someone nearby to handle it and prevent harm to innocents, that was what Endo Yukari wanted to convey.
Indeed.
If there was a possibility of endangering those around him, Rozen didn't mind voluntarily accepting monitoring from the Lion King Agency. If necessary, he wouldn't mind being killed to prevent harm to others.
Compared to being consumed by corruption and causing harm to those around him, Rozen preferred to become like that.
Unfortunately, Rozen himself was much more proficient in magic and jujutsu than Endo Yukari, and even surpassed her by far, so he was very aware that there was nothing to worry about.
Certainly, the Fourth Primogenitor was very terrifying and powerful, and it was not surprising that such an existence sealed inside a human body might break free at any time.
But for the Fourth Primogenitor to break free from Rozen's seal was impossible.
One must know that the Primordial Rune, as the source of the seal, was something even the main god of Norse mythology, Odin, could only sacrifice one eye to obtain, even though it was coveted by the gods.
At the same time, it combined numerous runes, sigils, and the command spell system of Chaldea, and even connected with the Crimson Wing Formation, embodying all the knowledge, power, and achievements of Rozen's life.
Such a seal, infused with the divine power of Kinu and Gyokuto, and with Rozen's Mind's Eye constantly adjusting it, could not be broken unless the original had the power to nullify all spells, even to the extent of controlling them, like Solomon.
So far, Rozen had never felt any signs of the seal being touched, not even a trace, indicating how strong the seal was.
Of course, there was still the possibility of the seal being broken.
If Rozen really unlocked the three seals, it was highly likely that he would be devoured.
After all, it was Rozen himself who unlocked the seal.
If only the first seal were unlocked, the impact on the mind and will would not be too strong, and with Gyokuto guarding the mind, as long as Rozen didn't excessively use the power after unsealing, he wouldn't be devoured.
However, once the second seal was unlocked, the threat would greatly increase.
If the third seal was unlocked, it would be equivalent to almost completely releasing the seal inside the body, and the restraint on the Fourth Primogenitor would be at its lowest point.
By then, Rozen would probably be very dangerous.
During these months, Rozen had somewhat attempted to unseal the seal and finally confirmed the limits of the unsealing.
Unsealing the first seal, Rozen could only sustain for about an hour.
Unsealing the second seal, Rozen could only sustain for about ten minutes.
Unsealing the third seal, Rozen could only sustain for about three minutes.
Once the designated time was exceeded, Rozen's mind and will would be in danger of being devoured, and ultimately, it would be irreversible.
Moreover, these seals could only be removed once a day, and the seal needed twenty-four hours to stabilize again before it could be unsealed again.
Otherwise, if the seal was directly unsealed for the second time within twenty-four hours, the seal that hadn't stabilized yet might immediately collapse, which was very dangerous.
On the other hand, as long as Rozen didn't repeatedly unseal the seal or simply didn't unseal it, there would be absolutely no danger.
Rozen himself was very clear about this.
This was not overconfidence, nor was it Rozen's high self-esteem. It was confirmed after numerous experiments and explorations.
Moreover, even if there was a possibility of the seal in Rozen's body being broken, there were people around Rozen who could intervene.
Not to mention Kinu and Gyokuto, a certain indifferent Heroic Spirit had been silently following Rozen all the time, and with their abilities, they were much more reliable than any monitor from the Lion King Agency.
Therefore, Rozen didn't need monitoring or protection from the Lion King Agency at all.
Given this...
"I can't think of a reason to voluntarily accept surveillance," Rozen said truthfully.
"Regardless?" Endo Yukari confirmed.
"Regardless," Rozen affirmed.
"...Then there's no other way," Endo Yukari fell silent for a moment, then sighed.
Just when Rozen thought the other party was finally giving up...
"I heard that you seem to enjoy studying magic and jujutsu," Endo Yukari said out of the blue, without any reason.
This statement surprised Rozen.
"Could it be..." Rozen blinked.
In such a situation, Endo Yukari said so.
"Although the Witch of the Void has some privileges on Itogami Island, allowing you to read good magic scripts, jujutsu scrolls, and various research books, those are at best things that can be leaked without consequences. The real secrets and arcane arts, I believe Minamiya Natsuki doesn't have the authority to let you browse through those," Endo Yukari muttered to herself.
"The fact is, Itogami Island is ultimately just an artificial island, established only a few decades ago. Unlike the Lion King Agency, if you trace back, it originated from the Heian period to protect the palace from malicious spirits and demons. Therefore, it is an organization older than the current Japanese government, and who knows how much knowledge has accumulated from ancient times to the present."
The implication was clear without even needing to guess.
"Let's make a deal!" Endo Yukari grinned, finally revealing her plan. "As long as you accept Himeragi Yukina as your monitor, I will provide you with the valuable knowledge accumulated within the Lion King Agency, using the authority of a special instructor of the Lion King Agency's magical department and the promise of the Three Saints."
For Rozen, this was a huge temptation.
"How about it?" Endo Yukari inquired.
As for Rozen...
"You really brought out something incredible, didn't you..." Rozen squinted his eyes.
"Can I consider it a yes?" Endo Yukari confirmed again.
"...Since the Lion King Agency is willing to do something like that, why should I refuse?" Rozen pondered for a moment, then said casually.
"Very well," Endo Yukari nodded in satisfaction.
Thus, the two sides reached an agreement.
