High God's Forest, an affiliate organization of the Lion King Agency, located on Mount Oe in Kyoto Prefecture, is an institution that gathers orphans with spiritual power potential from all over the world and trains them to become Attack Mage.
So-called Attack Mage refer collectively to magi, spiritualists, and others possessing methods to combat demonic beings.
Military and police special forces personnel, employees of private security firms, individuals hired by other organizations… Attack Mage have all sorts of identities. The skills and systems they use vary widely, but no matter how they're categorized, they are all experts in dealing with demons.
To demons, Attack Mage are natural enemies, because many of them live solely by hunting demons, like assassins.
High God's Forest is an institution established for cultivating such talents and only admits children with spiritual power potential.
Although these children grow up to take various paths, without exception, they are all female.
Because females are more prone to possessing spiritual power potential—at least in this country. This is also the origin of the role of the Sword Shaman.
Because of this, High God's Forest appears on the surface to operate as a girls' boarding school and, in reality, does function as a training institution for girls.
And Kaiser, starting from three years ago, was thrown in here to receive education...
In other words, he was the only male in the entire High God's Forest—the sole male student attending a girls' school...
"Damn, this kind of setup is pretty much main character level."
Kaiser held his head, looking unsure whether to feel happy or sad.
Attending a school full of beautiful girls… isn't this treatment straight out of a light novel protagonist's handbook?
So, shouldn't he be happy about it?
Kaiser felt a bit conflicted.
Suddenly—
"Kaiser, the only male student in High God's Forest."
It was a somewhat stern, yet not cold, and still very young voice.
The voice came from in front of Kaiser, from behind a hanging screen.
At this moment, Kaiser stood at the center of a spacious worship hall, like in a ritual. In front of him were three figures concealed behind a curtain, their true appearances entirely obscured, only vague outlines and shadows visible.
"Do you know who we are?"
That deliberately authoritative young voice made Kaiser sigh.
"I do," Kaiser mustered some energy and said, "The Elders of the Lion King Agency, leaders of the organization, known as the 'Three Saints'—humanity's strongest Attack Mage."
The three people before Kaiser were indeed, both in name and in practice, the leaders of the Lion King Agency, the highest-level spiritualists and magi.
Kaiser could clearly feel that although the three hid behind a curtain, the aura around them was terrifyingly still.
With such an aura, it was no wonder they were called the strongest Attack Mage—even more mysterious than Seishuin Ena in her possessed-by-god state.
Of course, to Kaiser, these three could be summed up with one word—weak.
As a result, Kaiser's tone was very casual, prompting the three behind the curtain to exchange glances.
"You were taken in by the Lion King Agency on the coast three years ago and brought to High God's Forest," one of the Three Saints began to speak, seemingly unconcerned with Kaiser's overly casual demeanor, as if tacitly acknowledging that he had earned that right.
"It was we who issued that decision. Do you remember?"
According to his backstory, Kaiser had awakened after sleeping for tens of thousands of years, and upon awakening, he remembered nothing—he didn't know who he was, what made him special, or even basic common sense.
To put it simply, his setting was equivalent to a newborn three years ago—he understood nothing.
That left Kaiser not knowing where to start with his complaints. He could only sigh again and say:
"Well, it did happen, so what?"
What exactly were these three heads of a matchmaking agency trying to do?
"You're already sixteen this year. It's about time you left High God's Forest, graduated, and became independent," one of the Three Saints spoke. "You've spent three years at High God's Forest; you should have learned quite a bit, right?"
"Mostly general knowledge and academics," Kaiser said flatly. "The rest is just some martial arts and weapon-based combat techniques."
"What about sorcery? What about magic?" another of the Three Saints asked. "Your instructor was Enju Yorigami, right? She's a master of both sorcery and magic—she can even be called an all-rounder."
"Unfortunately, I only learned martial arts and systematic demon-fighting combat techniques. Whether sorcery or magic, I didn't learn any," Kaiser looked at the three behind the curtain and said with a half-smile, "Master Enju never taught me those. She said some people were afraid I'd go out of control if I grasped power."
The Three Saints immediately fell silent.
"So, what did you summon me for this time?" Kaiser didn't want silence and asked bluntly, "Just say it directly. That'll save us all a lot of trouble, right?"
If others saw Kaiser speaking to the Three Saints like this, they'd probably be scared pale.
The Three Saints were humanity's strongest Attack Mage and leaders of the Lion King Agency. Meanwhile, Kaiser was just a trainee from a subordinate training institution under their command. The difference in status was vast. Speaking like this, with such tone, was extremely rude and completely disrespectful.
However, though it should've been like that, the atmosphere in the room was the opposite.
At this moment, the young man standing in the center of the hall felt far more like a king. Every gesture and movement exuded powerful authority. Instead, it was the Three Saints who seemed subordinate, completely overshadowed by a teenager.
This left the three inwardly astonished, unable to suppress a shared thought.
"Could it be… he's already awakened?"
The three couldn't confirm it, but that didn't stop them from continuing.
Because what they were about to say next concerned not just the Lion King Agency—but the entire world.
"Since you already possess basic knowledge, you should've heard of the Fourth Primogenitor, right?"
The youthful yet dignified voice sounded, causing Kaiser to narrow his eyes.
The so-called Primogenitor referred to the emperors who ruled over vampires.
They were the oldest and most powerful vampires, existing in this world since long, long ago—even before the heavenly gods vanished. They were ancient beings.
Each of them commanded tens of thousands of troops, established autonomous nocturnal empires on three continents, possessed countless blood kin, and were themselves comparable to entire armies. They controlled terrifying familiars like natural disasters—able to destroy cities, alter geography, and obliterate tens of kilometers in a single strike.
As someone familiar with the original work, Kaiser naturally knew of the Primogenitors and was well aware that the three vampire Primogenitors were among the most powerful beings in the world—both in status and strength, they were on par with Campiones from the previous world, feared by all.
And the Fourth Primogenitor, also known as the "Kaleid Blood," was said to command twelve disaster-class familiars—immortal and undying, with no vampire kin, no desire to rule, existing solely for slaughter and destruction.
They were known as the world's strongest vampire, also called the Phantom Vampire. Many believed they were merely an urban legend and not real.
But the truth was—the Fourth Primogenitor truly existed.
Because they were the protagonist of this world.
"There have been multiple tragic catastrophes in history, and all of them were later confirmed to involve the Fourth Primogenitor."
"Though they have no vampire kin or territory, the Fourth Primogenitor is real."
"They have awakened several times and fallen into slumber again and again. Now, they've awakened once more and returned to the human world."
With each of the Three Saints speaking in turn, a photograph suddenly descended from above, landing in Kaiser's hands.
Kaiser caught it, took a closer look—and froze.
"This is the Fourth Primogenitor."
The youthful and dignified voice sounded again.
"They are currently in the Demon District of Tokyo Metropolis, on the artificial island Itogami City."
What followed was a calm yet demonic voice.
"We hope you can become the observer of the Fourth Primogenitor. Head to Itogami Island and monitor them. If determined to be a threat—eliminate them with all your strength."
Finally, an elderly male voice spoke.
However, Kaiser's attention was no longer on the three of them, but entirely focused on the photograph in his hand.
Staring at the person in the photo, Kaiser fell into a long, long silence.
"Well? Is something wrong?"
The Three Saints seemed to notice Kaiser's abnormal reaction and asked.
"…No, nothing wrong," Kaiser finally moved his gaze from the photo and looked back at the Three Saints. "The only problem is probably—why did you choose me for this task?"
Though he said that, Kaiser already understood the reason.
"There's a terrifying power sleeping within you."
"That power is enough to slay even the immortal Primogenitors."
"If you can wield it properly, even the Fourth Primogenitor should be within your ability to handle."
One by one, the Three Saints spoke, and none of their words surprised Kaiser.
Kaiser then looked down again at the photo in his hand.
In the picture, a girl with expressive, large eyes and long black hair tied up with a hairpin—making it look like short hair at first glance—was smiling with a cute expression. Her facial features and body gave a slightly youthful impression. She looked to be a middle school student.
"She… is the Fourth Primogenitor?"
Kaiser had to confirm.
"She is."
"Her true name is Nagisa Akatsuki, a third-year student at the private Saikai Academy Middle School."
"You will also transfer into that school and become her observer."
The Three Saints spoke with certainty, leaving Kaiser speechless for a long time.
So… wasn't I given a light novel protagonist's setup?
Why am I now playing the heroine's script?
The Fourth Primogenitor, Nagisa Akatsuki.
This joke… is a bit too much, isn't it?
