Shizuka Koyomi left.
Once Rozen agreed to her request, she no longer had any reason—or ability—to stop him. Her only option now was to make arrangements as quickly as possible to prevent any unforeseen incidents.
However, compared to the situation at Kannawa Lake, Rozen's circumstances were undoubtedly weighing more heavily on Shizuka Koyomi's mind.
After all, the changes that had occurred within Rozen were potentially far more serious than anything happening at Kannawa Lake.
Shizuka Koyomi had to take action regarding this matter.
Rozen and Yukina watched her leave before turning to face each other.
"You're really coming with me?"
Rozen asked, just to confirm.
"Of course," Yukina replied firmly. "Because I am your monitor."
Earlier, when Shizuka Koyomi had suggested that Yukina accompany Rozen, Yukina had spoken up before Rozen could respond.
"Even if you refuse, I will still follow you."
Her expression at that moment had been deadly serious.
Clearly, she wasn't joking.
That was why Rozen had agreed to Shizuka Koyomi's request without hesitation.
Still, he found Yukina's reasoning somewhat amusing.
"There's no longer a Fourth Primogenitor sealed inside me. The Original is gone, and I'm just an ordinary human now. Do you still need to keep watch over me?"
That was Rozen's argument.
The Lion King Agency was a special organization dedicated to preventing magical disasters and terrorist activities. Their usual targets were Demons—he had never heard of them monitoring humans.
But Yukina had an answer for that.
"Precisely because you are human yet possess such dangerous power, I must monitor you. To ensure you don't make a grave mistake and lose control."
Yukina was unwavering in her stance.
After today's events, Rozen's situation would undoubtedly become known to the Lion King Agency—and eventually spread across the world.
The news that the Fourth Primogenitor had completely vanished, with Rozen having stolen its power, would shock the world's major powers and influential figures, forcing them to reassess their stance toward him.
In the past, Rozen had summoned deities, been recognized as a divine child under divine protection, and now he had even taken the power of the Fourth Primogenitor—whom he had once sealed—and erased it entirely. These extraordinary feats would make it clear to everyone that Rozen was an existence even more fearsome than the world's strongest vampire.
And yet, he was still human.
No one could predict how his presence would reshape the world's power dynamics.
Yukina didn't know either.
But there was one thing she was certain of.
"Senpai truly is a dangerous individual. I must keep a close eye on you."
Yukina reaffirmed her role as his monitor.
This was likely the Lion King Agency's stance as well.
They would never revoke Yukina's mission or allow Rozen to go unwatched. If anything, they would intensify their surveillance to prevent any greater threats from emerging.
Among humans, Rozen was probably the only one who warranted such caution and wariness from the Lion King Agency. But that just showed how extraordinary he was.
From now on, the Lion King Agency would never be able to ignore Rozen's existence.
Rozen had already been prepared for this when he decided to reveal the truth.
"Fine, do as you please."
Rozen shrugged, acting indifferent.
But then—
"Let me make one thing clear—this time, I may not be on your side."
Rozen looked directly at Yukina.
"For Nagisa and Avrora, I might very well become an enemy of the Lion King Agency. Are you really okay with that?"
Though the Lion King Agency had already compromised with Rozen, if Nagisa and Avrora were harmed because of their actions during the Kannawa Lake incident, Rozen would never forgive them.
In that case, he and Yukina would truly become enemies.
"I will do everything in my power to prevent that from happening."
Yukina's response was resolute.
"And if it still happens?"
Rozen pressed further, refusing to let her evade the question.
"It won't." Yukina remained stubborn, her voice firm. "I absolutely won't let it."
It seemed she had made up her mind.
If Rozen truly became an enemy of the Lion King Agency, Yukina's position would become untenable.
Seeing Rozen's attitude toward the Lion King Agency and Shizuka Koyomi's wariness of him, Yukina felt she had to take this matter seriously.
She didn't want Rozen and the Lion King Agency to become enemies.
Because if that happened, Yukina would inevitably have to leave Rozen—or worse, she might even receive orders to eliminate him.
She couldn't bear that thought.
So even if it wasn't just for Nagisa and Avrora, Yukina felt she had to make this trip.
Rozen smirked, as if seeing right through her thoughts as he met her unwavering gaze.
"Then do your best."
With that, he snapped his fingers.
A magic circle spun into existence on the ground.
"Roar!"
A Wyvern burst forth from the circle, its wings beating violently as it soared into the sky above Saikai Academy's rooftop.
"This is…?"
Yukina blinked in surprise.
"We're riding this."
Rozen stated it plainly.
If they went through the proper procedures to leave the island, it would take far too much time. And since the distance was too great to accurately determine spatial coordinates for a teleportation jump to the mainland, riding a familiar to Shinji Lake was the only viable option.
If either Nagisa or Avrora were one of Rozen's contracted familiars, he could have used spatial transfer to jump straight to them.
Thanks to the absolute contract, no matter how far apart they were, Rozen could always sense his familiars' locations, allowing him to teleport directly to them—or even use reverse summoning to appear at their side.
That was how he had instantly traveled from the Walpurgis Royal Academy to the secluded estate of the Izanagi clan, arriving in a single day before burning their mansion to the ground.
But now, without a familiar on the mainland, Rozen had no choice but to cross the sea the old-fashioned way.
"Eek!"
Yukina let out a startled cry as Rozen suddenly scooped her up.
"S-Senpai…!?"
Rozen, however, remained completely unbothered.
With a single leap, enhanced by his Kongouriki reinforcement, he soared high into the air and landed smoothly on the Wyvern's back.
"Roar!"
The Wyvern let out an excited cry before beating its wings and darting toward the ocean like a gust of wind.
Their destination: Shinji Lake, in the Shinokuda region of Tanzawa, Kanagawa Prefecture, Tokyo.
