The conversation that took place in the antique shop, Rozen naturally couldn't have known about it.
However, even without knowing, it's not hard to guess.
Seeing the Lion King Agency offer such a trade, handing over the very essence of their inheritance just for a chance to monitor him, Rozen only needs to think for a moment to realize that it's not just because the Fourth Primogenitor, the strongest vampire, is sealed within him, but also because of the abilities he displayed during that sealing battle.
"No matter in which world, the descent of gods is the greatest and most incredible miracle."
So, Rozen had already guessed that the awakening of the God of Fault by him would definitely become the focus of attention for all factions.
How did it happen?
What exactly is going on?
How was it implemented?
Where exactly is the mystery?
And why is Rozen able to possess such abilities?
Each of these questions will lead all the major powers in the world to focus their attention on Rozen and take action and countermeasures accordingly.
As the national secret agency, the Lion King Agency is just taking a stance that requires them to take action before anyone else.
After all, Rozen is in this country, and even though Itogami Island is an administrative autonomous region, it still belongs to this far eastern island nation at present, so naturally they must take action first; otherwise, if something goes wrong, the country, and they themselves, will be the first to be affected.
"If I hadn't shown enough strength, maybe they would have sent someone to assassinate me directly," Rozen sneered.
Compared to handing over the very foundation of their existence, they would definitely prefer to do this.
However, seeing Rozen's ability to confront the Fourth Primogenitor head-on at the Blazing Banquet, wouldn't they be cautious even if they wanted to take assassination action?
Assassination itself is a double-edged sword; if used well, it can eliminate enemies, but if used poorly, it will provoke enemies.
If the Lion King Agency's assassination ultimately fails, then they may not be able to bear Rozen's wrath, and in the end, they may even implicate the entire country and the entire world.
With this in mind, the Lion King Agency can only compromise and sacrifice, resolutely paying a high enough price to recruit Rozen.
"As a result, the Lion King Agency has taken the same attitude as the Artificial Island Management Cooperative."
For now, this still satisfies Rozen.
However, this satisfaction will definitely not last.
Because not everyone will adopt this attitude.
Perhaps one day, there will be entities willing to obliterate Rozen at all costs or take action against Rozen in secret.
Those are the invisible threats.
Of course...
"I've seen these kinds of threats many times."
Therefore, whether in terms of intelligence or strength, Rozen doesn't think he will lose.
If it were before, Rozen would probably have to think carefully.
However, now, after becoming a living spirit of a Primogenitor, even if Rozen cannot act without any scruples, he does not need to be afraid.
Even without releasing the seal, after obtaining the magic power surpassing the Dragon Veins provided by the seal within him, Rozen can unleash the power of Kinu, Gyokuto, and Altera to the fullest. Plus, with Hokuto, who has already officially formed an absolute contract, even if the opponent is a Primogenitor, Rozen can confront them head-on.
Moreover...
"After returning, I'll start researching the Lion King Agency's inheritance."
Rozen can still continue to improve.
There is still a lot of room for progress ahead of him.
Rozen looks forward to it like this.
It's just a pity that Rozen has already forgotten.
Today, he still has an extremely huge trouble to solve.
...
In the western district of the Artificial Island, at the top floor of the luxury residential apartment, Rozen's home.
At this moment, in the living room, Kojou, Nagisa, and Avrora stood hiding in the corner of the hallway, nervously watching the scene in the living room.
There, Natsuki stood expressionless, tapping her lace fan against her palm.
"So, explain to me why you took a transfer student from the mainland to that kind of place, Nichiyo," Natsuki said with an unprecedented icy expression, making such a judgment.
In front of her, Rozen sat on the sofa.
But...
"...Before that, can you please release the 'Lawbinding Shackles' on me...?" Rozen was tightly bound by the magic of the 'Lawbinding Shackles'.
"You tied me up with the 'Lawbinding Shackles' as soon as I entered the door. Isn't that too ruthless?" Rozen protested.
After separating with Yukina, Rozen went straight home, only to be bound like this as soon as he entered the door.
Because things happened too suddenly, without any warning, and without feeling any killing intent, hostility, or malice, even Rozen was stunned and fell for it, so he had to protest.
Even...
"Even if I hand you over to the Special Zone Security Unit as someone who committed an indecent assault, that would be okay right?" Natsuki's extremely cold words made Rozen completely shut up.
"Bringing a middle school transfer student to a hotel district, there should be enough reason for the Special Zone Security Unit to arrest you, right?" Natsuki directly transformed into an impartial law enforcer.
"No no no! I didn't do anything! Natsuki-nee!" Rozen quickly declared his innocence.
Natsuki accepted it quite readily.
"Indeed, you're not the kind of man who would take a schoolgirl straight to a hotel room, otherwise the girls at school would probably all end up pregnant before marriage."
Natsuki calmly used a statement that made Rozen's mouth twitch, then continued speaking.
"But why did you take a transfer student from the mainland to such a place, and why did you bring back something like this? Your dear sister is very curious, aren't you going to explain?" Natsuki said so, holding a book in her hand.
It was the Grimoire Rozen brought back.
As a witch, no one understood Grimoires better than Natsuki.
"No. 282...?" Natsuki muttered the title of the Grimoire in her hand while coldly snorting.
"You really brought back something rare," Natsuki's attitude was not surprising.
After all, Grimoires are generally extremely dangerous things. If things go wrong, and a Grimoire goes out of control, the island would probably be doomed.
As a national attack mage, Natsuki cannot ignore the existence of such things.
But...
"Natsuki-nee, you can't possibly not know, right? This Grimoire doesn't pose any danger!" Rozen offered this explanation.
As the highest-ranking witch, Rozen didn't believe that Natsuki wouldn't know what kind of Grimoire No. 282 was.
"It's just a pure library that can only be used to record a large amount of knowledge," Rozen stated.
"That's correct," Natsuki admitted.
But Natsuki still wasn't convinced.
"Where did you bring back this Grimoire from? I really want to know," Natsuki stared at Rozen, her coldness turning into a smile.
"You'll explain it to me, won't you, Nichiyo?"
With that, Rozen felt helpless.
So, Rozen explained everything, from cause to effect.
Anyway, it's not something worth hiding.
Of course, Natsuki's mood is probably going to get even worse.
