Rozen's unannounced departure caused chaos, which now officially concluded with his return.
However, from everyone's accounts, Rozen came to understand just how many problems his disappearance had caused.
Not only had those including Natsuki exhausted every possible means to find him, but others had also stirred up no small amount of trouble over the matter.
After all, in this world, Rozen was both the Divine Child once delivered by the gods and the living being who sealed the Fourth Primogenitor. Combined with his public defeat of the Third Primogenitor during the Harurouin Festival, he was already under close surveillance by nations and major organizations worldwide, regarded as an important figure by entities like the Lion King Agency.
For such a person to vanish without warning, leaving no clues, it was impossible not to cause waves.
Beyond Natsuki and the others, the Lion King Agency had made major moves to locate Rozen. Nations and factions globally closely followed the matter, the Management Cooperative dispatched Special Security Teams for island-wide searches, and even the Third Primogenitor he'd once battled showed concern, reportedly offering assistance to Itogami Island. The Ardeal Principality stationed on Itogami also declared their readiness to help at any time.
Furthermore, upon receiving news, Aldegyr's First Princess even offered to lend her nation's elite "Holy Ring Knights" to aid the investigation, personally visiting Itogami Island and nearly causing a major incident.
"That damn princess..."
Hearing this, Rozen's mouth twitched involuntarily.
He was certain the princess hadn't acted out of concern, but purely for amusement.
At least, Rozen couldn't imagine La Folia worrying over him.
In contrast, Natsuki caused the biggest stir, even confronting territories of the Three Primogenitors—particularly barging directly into the Chaos Zone to confront Giada.
Given Rozen had just battled this Third Primogenitor, Natsuki's suspicion toward Giada was understandable.
In summary, Rozen's two-month disappearance kept Itogami Island in turmoil, resulting in numerous criminal organizations being exposed and many underground incidents being aborted—collateral damage from the chaos his absence created.
Of course, Yukina also employed extreme measures investigating every possibility, while Asagi—the Digital Empress—nearly breached firewalls worldwide, infiltrating national databases globally in her search.
This made Rozen realize:
"Unknowingly, I've gathered so many remarkable people around me."
With such talents working together, creating massive disturbances was inevitable.
Moreover...
"After you disappeared, Avrora's mental state became extremely unstable. Her powers even went berserk once, nearly freezing all of Itogami Island."
Yukina's grave report made Rozen realize his absence hadn't just caused chaos—it nearly brought existential crisis upon everyone.
"It seems I really can't casually disappear anymore."
Rozen deeply internalized this lesson.
Immediately, he retrieved his local phone to contact Nagisa and Avrora, but couldn't get through—likely due to signal issues—so switched to messages announcing his return.
According to Kojou, Nagisa and Avrora were currently visiting their grandmother's home in Kanto's Tanzawa hinterlands under Gajou's guidance, and wouldn't return until after New Year's.
"Nagisa and Avrora were truly worried sick. Make sure you apologize properly later."
Only after delivering this did Kojou depart.
During Rozen's absence, the Akatsuki residence destroyed by nosferatu had been rebuilt. Kojou and Nagisa had moved back under Gajou's supervision beforehand.
Reportedly, Tokoyogi Yuuma was also living there now—effectively cohabiting with Kojou.
Avrora had been taken in by Nagisa.
With Avrora emotionally unstable, staying at their usual place would trigger memories of Rozen, so Natsuki suggested she temporarily stay with Nagisa. Thus, Avrora joined Nagisa and Gajou's trip under the guise of relaxation.
"So you're living alone with Yuuma now?"
"Don't make the mistake all men make, Kojou."
Motoki and Asagi teased with ill intentions.
"Like hell I would!"
Kojou's flushed face—whether from anger or embarrassment—prompted him to drag both away upon leaving.
With school on winter break, the group agreed to meet later for proper catching up.
Yukina, however, remained behind, sticking to Rozen like glue.
"This time I won't let Senpai leave my sight for even half a second."
Her resolute declaration prompted Natsuki's intervention.
"I've no spare rooms here, Sword Shaman."
Her tone bordered on expulsion.
"No matter." Yukina responded without hesitation: "I'll share Senpai's room."
Dead silence followed.
"Yukina-chan, how bold~"
Kanon's cheeks pinkened.
"Sharing a bed..."
Astarte stated with clinical bluntness.
"...To say such things before me—you've courage, Lion King Agency brat."
Natsuki's gaze turned dangerous.
Only then did Yukina realize her phrasing.
"N-Not like that!"
Flustered, she desperately backpedaled.
Watching this, Rozen could only sigh.
Because his internal harem had erupted.
"...So this is your so-called 'terrifying enemy'?"
"Just flaunting your popularity? Making us worry for nothing? You wanna die?"
"Rozen-sama..."
Artoria [Alter], Jeanne [Alter], and Serenity's voices dripped icy disdain.
"Senpai..."
For the first time, Mash's voice carried unmistakable displeasure.
What could Rozen do?
Only smile helplessly.
Thus, with Rozen's return, the two-month turmoil finally concluded.
The Management Cooperative could presumably breathe easier now.
As for other factions' reactions upon learning of his return?
Rozen pondered this.
Unbeknownst to him then—
A new storm was already brewing.
