Six months had passed in the blink of an eye.
A lot had happened in that time, but… if one had to summarize some of the most striking events…
First: the wedding of Kazuya and Serafall.
It wasn't merely an extravagant ceremony between a Supreme Demon King and the "anomalous human" who had already become legend.
It was the trigger for a tectonic shift in the supernatural world.
From that day forward, the Demons formally sealed an alliance with Chaldea.
And with that, they joined the Pleiades group, becoming part of the coalition that united virtually every relevant supernatural force on the planet.
And, of course, there were consequences.
The main one was this: humans were catapulted to the very top of the hierarchy.
Not through their own merit, of course, but because they stood under the wing of the only organization capable of facing any supernatural faction on equal terms: Chaldea.
Many humans who knew of the supernatural world—hunters, heirs of magical bloodlines, informed governments, secret societies—felt an involuntary surge of arrogance.
That old feeling of "now it's our turn."
But that pride didn't last.
Not when every supernatural race clearly remembered that all of this was only happening because of Chaldea.
Without them, humans would still be seen as resources, pawns, or—at best—prey.
Thus, as quickly as it had risen, human ego was drowned.
And the new world order began to stabilize… silently.
But it wasn't as if this were truly anything new.
The Demons, despite not having officially joined the alliance earlier due to… well, their past mistakes, had never actually been distant. In practice, they had been orbiting the coalition for a very long time.
Why?
Because Kazuya allowed it.
They remained in a sort of neutral zone: tolerated, watched, and above all, waiting.
Waiting for the decision everyone knew would come sooner or later:
whether Kazuya would truly marry Serafall.
And when he finally decided "yes," everything changed… and at the same time, nothing changed.
The only difference was that what had previously existed only as tacit permission, an undeclared presence, a nameless coexistence, was now official—stamped and recorded before the entire supernatural world.
Their position, which had previously wavered between "tolerated" and "hanging by a thread," became stable, recognized, and legitimized by the force that bound all the others together.
In the end, the wedding merely turned into law what had already existed in practice.
So politically, almost nothing had changed.
But on a personal level… that was an entirely different story.
The Gremory family, for instance—with the exception of Rias and her peerage—still burned with dissatisfaction, and the reason was easy to understand. Kazuya had reduced Sirzechs, the former "Demon King," to little more than an impotent eunuch, stripped of power and reduced to the frailty of an ordinary human. A direct, proportionate, and cruelly precise punishment for his arrogance in trying to manipulate him.
And as if that weren't enough, a little over a month after Serafall and Kazuya's wedding, the fall of Grayfia occurred.
Her punishment—equally just, equally devastating—swallowed her pride whole. And a woman like Grayfia Lucifuge… could not live without it. Unable to accept a life in which she had to bow her head, unable to bear the humiliation of being reminded of her own failure every time she looked someone in the eye, she chose the only path she believed was left to her.
She took her own life.
She left behind a still-young son and a husband who no longer even had the strength to stand. It was the kind of decision that silently destroys an entire family and that none of them would ever dare put into words.
In the end, everyone understood the reason… but that didn't make the pain any less bitter, nor the resentment any less alive.
The silver lining was that Serafall intervened and asked Kazuya to bring Grayfia back to life—this time with a face that had not been disfigured by him. In exchange, Grayfia would accept to work as a maid at Chaldea's facilities, and thanks to Serafall's mediation, her punishment was lifted.
Serafall also tried to negotiate Sirzechs' situation, seeking to free him from his own punishment. However, Kazuya remained inflexible. In the end, she gave in and offered him her last remaining virginity in exchange for at least restoring part of Sirzechs' demonic power—though he would remain without his [Power of Destruction] and without recovering his masculinity.
And it wasn't only the Gremory family that carried bottled-up frustration.
A good portion of the demonic nobility was also discontent.
After all, many of them had no idea about the old plan of the Four Great Satans to marry one of their own to Kazuya. To those nobles, everything seemed to have happened far too quickly, as if the world had been turned upside down without asking permission.
And there was resentment.
The kind of resentment that only blossoms when wounded pride and deep fear coexist.
After all, Chaldea had wiped out a considerable portion of the demon population, and to most of these nobles, all of that had happened because of a simple "overreaction to a conflict with humans."
They still didn't seem to understand—or pretended not to understand—that in the new world, humans protected by Chaldea sat at the very top of the food chain.
And touching them had consequences.
Devastating consequences.
For weeks, dissatisfaction simmered in the Underworld. Secret meetings, whispered conversations in dark corridors, hateful glances when they thought no one was watching.
But Kazuya settled everything.
And ever since that day, no one questioned his position again.
From that moment on, the Underworld acknowledged him as its ruler—despite the irony of him being, of all things, a human.
Or perhaps precisely because of it.
For there was no living supernatural being who would dare challenge someone capable of bending the entire Underworld so effortlessly… and still smile as if it were the most trivial thing in the world.
Well, setting the Demons' position aside, an inevitable detail emerged right after Serafall finally obtained her long-desired "husband."
A certain little angel of the Brave Saints simply exploded with jealousy.
For two whole months.
Yes—two months of pure, silent, radiant sulking bright enough to make half the Underworld believe a new luminous race had been born. She would appear whenever Serafall was with him, cross her arms, puff out her cheeks, and make passive-aggressive comments so sweet that even God would be proud.
And, inevitably, she gave in.
Or rather, Kazuya won—as he won against any other force of creation.
And so she became his fiancée… and soon after, his wife.
As for the old fear that the "wedding night" might turn her into a Fallen Angel?
Of course that was taken care of.
In a way so simple and so definitive that even Heaven gave up questioning it.
Nothing that an almost-omnipotent being couldn't fix with a single thought.
But she wasn't the only one.
Yasaka, who had been maintaining an increasingly close—and almost "innocently" too close—relationship with him, eventually declared her feelings in a direct, elegant, and impossible-to-refuse manner.
And finally, even Kuroka—who over the past months had grown accustomed to prowling around him with the ease of a cat that had already decided which house she wanted to rule—spoke up. And when Kuroka decides something… well, everyone knows it's pointless to resist.
In the end, he gained four new wives.
Fortunately, Kazuya was… well, Kazuya. And that meant that no matter how chaotic his married life became, he still found time for everything. And for everyone.
He alternated between one-on-one moments and group gatherings, balancing each relationship with the ease of someone who had already seen a thousand possible futures and knew exactly how to avoid trouble.
But that wasn't the only thing that happened. He finally used up the secret stockpile of rolls he had been saving in the [Fate Gacha].
For months he had been hoarding those precious chances, waiting for the right moment.
And now, with the wedding official and his life stabilized at the top of the supernatural chain, he simply decided to… use them all.
That was how he essentially summoned every single one of his other wives, lovers, allies, and friends from Chaldea that he had missed.
Every one of them.
Without exception.
Well… almost without exception.
Because some Servants were still too problematic even by Chaldea standards—Vlad, Blackbeard, and a few other names that would embarrass anyone—and he preferred not to risk bringing that kind of madness back into his Chaldea.
The rest?
They all came.
And the result was exactly what any minimally lucid observer would have predicted: months of absolute chaos.
Arranging housing, assigning roles, defining territories, managing jealousy, preventing certain deities from starting ritual wars just to mark their presence, adapting an entire social structure to accommodate dozens of mythical figures…
It was hellish.
And paradoxically, wonderful too.
Beyond those two events, the remaining days passed peacefully, with nothing truly noteworthy. Kazuya enjoyed his time with his wives and friends, savoring their company while preparing for a long and well-deserved trip to another world.
Yes—he had finally discovered a method to cross dimensions thanks to some successful experiments with his [Second Magic]. And now he was ready to leave and have a little fun…
This time, alone.
Convincing hundreds of wives that they couldn't come along wasn't easy, but somehow he managed it. In truth, for them and everyone in Chaldea, the period he would be away would feel like "an instant." That was because Kazuya had perfected his [Innovate Clear] to the point of completely controlling the flow of time inside his inner universe. So his plan was simple: freeze local time while he traveled.
And let no one dare call him selfish.
Honestly, after everything he had done—every battle he had won, every world he had saved, all of humanity he had carried on his back—Kazuya had every right in the world to a real vacation. One without blowing anything up, without solving anyone else's problems, and without dealing with the unbearable politics of half the multiverse.
In fact, he had already made a bucket list.
And what a list it was.
From traveling to the DC universe just to personally beat up the Justice League and teach them a lesson about their twisted heroism… to visiting the Dragon Ball world and training with Goku purely on a whim—and maybe, just maybe, proving he could keep up punch for punch (which was relatively easy, since Goku was kind of a meathead anyway)…
That was it.
This was his moment.
And no one was going to take it from him.
After weeks of preparation, analyzing every possible variable and ensuring the High School DxD world wouldn't collapse without him—even with Chaldea temporarily out of the picture—Kazuya finally felt at peace with his decision.
Would humans go back to being treated like cattle?
Probably.
Would the political balance tip the wrong way again?
Very possibly.
But honestly? He had already carried this world on his back more than enough.
Still, just to be safe—and because he knew full well the universe's tendency to screw him over out of sheer stubbornness—he left behind a clone to keep everything under control. An extremely competent clone, mind you, with enough power to stop any cosmic stupidity while he was away.
And so…
The day arrived.
The day Kazuya would finally cross into another world.
The day of his long-awaited vacation.
The day he would, for the first time in a very long while, do something just for himself.
And nothing—absolutely nothing—was going to ruin it.
.
.
.
.
.
.
Kazuya stretched as if he had just woken up from a pleasant Sunday nap, even though he was floating in a completely empty, silent, infinite space—a sea of darkness dotted with countless false stars.
False not because they were illusions…
But because they only looked like stars from where he was.
He hummed softly, the light and relaxed melody of someone who was officially on vacation for the first time since… well, since he had been born as Kazuya.
"Vacation, vacation, vacation…" he sang under his breath, hands behind his head, legs swinging in the void as if he were sitting on the edge of a pool.
The "stars" slowly pulsed around him, breathing. Each point of light was actually an entire world. A complete universe, with its own history, tragedies, logic, and chaos.
But to Kazuya, inside the [Outer Path], they were merely windows or doors.
He particularly liked calling them travel routes.
His [Second Magic] had created a multidimensional observation tunnel connecting thousands—perhaps millions—of possible, impossible, and hypothetical worlds. A garden of paths that only he could walk.
He spun once more in the air, completely carefree, and let out a lazy smile.
"Man… I deserved this even more than I thought…"
He reached out and touched the void. The lights vibrated, rippling like water touched by a fingertip. Colored waves spread outward.
"Let's see…" he muttered, tilting his mouth. "DC world? Tempting. But beating up Superman can wait a bit… I'd rather not be labeled an 'interdimensional villain' on the very first day of my vacation…"
The lights shifted.
Another star blazed fiery red.
Another glowed gold.
Another shone deep blue, almost calling to him.
"Dragon Ball?" He chuckled. "That's a good one too… but training with Goku right now means getting tired. And I just started my vacation…"
Yet another star flared intensely, pulsing like a giant heart.
Something about that glow felt… fun. Challenging. Chaotic. Light.
"Oh?" Kazuya raised an eyebrow, activating his [Omniscience] to check. Upon discovering it was a world where he would actually have trouble at his power level—where he wouldn't feel like a bored Saitama—he smiled faintly. "You look promising…"
He raised his finger.
Pointed at the star.
The light responded as if the entire universe had held its breath.
"Chosen…"
The decision was made.
And in a single instant, Kazuya leaned forward and vanished.
There was no explosion.
No trace.
No spatial distortion.
He simply moved.
Faster than light, faster than any concept of speed, beyond any natural law that dared to exist. Reality compressed around him, the [Outer Path] tunnel bloomed like a cosmic flower, and time itself seemed to bow in greeting as he tore through every possible barrier.
"This is gonna be fun…" His voice echoed into the void, full of anticipation.
And then…
He dove straight into the new world.

(A/N: And so, we've reached the end of the High School DxD arc.
To be honest with you — and I really do want to be honest — this arc drained me far more than I expected. I won't lie: there were moments when writing this part of the story became tedious, heavy, repetitive. Many times I found myself rereading sections and thinking, "I could've done this better," or, "I don't think this development turned out the way I wanted."
There were days when I almost deleted everything. There were nights when I seriously considered rewriting the entire arc from scratch. Believe me: the temptation to throw it all away and start over was very real.
But I also knew that if I did that, I would never escape that loop. I'd be trapped in an endless chase for perfection — and you would be trapped with me, with no progress, no advancement, no new worlds.
So I took a deep breath.
Grit my teeth.
And moved forward.
Because I knew that if I could reach this point, I could finally open the doors to the parts of the story I truly wanted to explore with more freedom. And now… we've arrived.
The DxD arc ends here.
And with it, a phase of the story full of excesses, exaggerations, madness, chaos — a phase meant mainly to show you who Kazuya really is, his past as the last Master of Chaldea, and everything else.
And the next world is exactly this:
Tensura.
A universe where power, diplomacy, evolution, and "creation" are uniquely intertwined.
A universe where Kazuya won't be a bored Saitama, where he will actually face challenges, and where he can finally unleash himself — but in a new way.
That's why I want to do this arc properly.
With care.
With attention.
With quality.
I was thinking of following a different rhythm from now on:
One big chapter, around 10,000 words, per week(Which would be equivalent to five 2k-word chapters that are normally posted daily, so you won't be losing anything — and I will simply gain more time to write, allowing the chapters to come out with much higher quality.)
I'll probably post it every Friday — every single Friday.
This is because I'm going to reread the Light Novel, revise material, and I genuinely want to raise the narrative level. Tensura deserves it. You deserve it. And I want to be proud of this part of the story — at least this part, I want to make as perfect as possible…
But… what do you think?
Do we continue with daily chapters?
Or can I switch to larger, weekly chapters — with more quality and development?
Tell me. Truly.
Your opinion matters a lot to me.
And thank you, from the bottom of my heart, for sticking with me until now.
It's because of that that I keep going.
See you in the new world.)
