A Journey Through the Multiverse from the Supreme Sovereign

"...I think you should give up on that idea. Be careful, or the teacher might get fired!"

The girl called Miyun-chan blushed and shouted, "...Hey, don't spout nonsense, Enoka!"

"Hahahaha!"

The surrounding students all burst out laughing at the two girls' bickering.

Yase Motoki looked at the beautiful girl seated beside him by the window, who was resting her cheek on her hand and gazing outside, and asked, "...Asagi, what kind of person is our new teacher?"

The girl resting her chin on her hand turned around. Though she was only a middle school student, she was dressed in an exceptionally fashionable manner.

She had pale golden-yellow hair and reddish-brown gemstone-like eyes. Her hairstyle was exquisite, and she wore light makeup.

Combined with her unusually developed figure, she was practically on another level compared to students her age—the campus goddess in the hearts of countless boys.

Hearing her childhood friend's question, Aoba Asagi merely rolled her eyes at him. "...How would I know what our new teacher is like?"

"I thought you knew everything."

Yase Motoki teased.

"Do you have some kind of misunderstanding about me? Oh, class is starting. Stop talking. We'll find out who the new teacher is soon enough."

Aoba Asagi waved her hand impatiently.

She certainly had the means to find out who the class's new teacher was in advance. The new teacher's information should have long since been entered into the school database.

But Aoba Asagi was not bored enough to investigate something like that.

The bell rang, and the students quietly returned to their seats.

Then, beneath the curious, expectant, and excited gazes of the children, a delicate little girl dressed in a Gothic Lolita gown, as petite as a doll, walked in.

At the sight of the little girl, Yase Motoki whistled. "...Hey, little miss, did you wander into the wrong room?"

"...This is Shiritsu Saikai Academy. We only have middle school and high school divisions here. The elementary school isn't here."

The other students who heard Yase Motoki's teasing snickered, and the classroom became quite lively.

Only Akatsuki Kojou turned pale as he stared fearfully at Nangong Nayue entering the room.

He had personally seen how this Witch slaughtered the beastmen on Gozo Island.

Akatsuki Kojou had never imagined that after seeing a demon by the roadside that morning, he would see a Witch in his classroom during class.

Could they really be here to destroy String God Island?

At that thought, Akatsuki Kojou grew even more terrified, his body swaying as though he might collapse at any moment...

Nangong Nayue, who had entered the classroom carrying her lesson plans, glanced at Yase Motoki. She lowered her head, quickly checked the student photos in her hand, and said coldly:

"...Yase Motoki, is it? Copy today's text ten times!"

Though Nangong Nayue was petite, she radiated authority. A single sentence silenced the noisy students, and they all sat up straight, not daring to make a sound.

Yase Motoki was no exception. One look from Nangong Nayue made him feel as if he had fallen into an ice cellar, and he swallowed every word he had been about to say.

Nangong Nayue placed her lesson plans on the desk, picked up a piece of chalk, and wrote her name on the blackboard.

Then she turned to face the middle school students and said, "...My name is Nangong Nayue. From now on, I will be your English teacher and homeroom teacher."

"...I hope you will not cause me trouble and will study properly—especially in my English class."

At that moment, someone suddenly said, "...Little Natsuki?"

"Shut up! When addressing a teacher, do not use words like 'little' or '-chan'! If I hear that word again, you will copy the text ten times just like Yase Motoki over there!"

Veins bulged on Nangong Nayue's forehead.

To be honest, that form of address had practically become someone's exclusive nickname for her. Nangong Nayue did not like hearing it from anyone else.

In an instant, the students fell silent in terror.

The Witch's authority was not something a group of ordinary students could withstand.

Although the students' noisy behavior was troublesome, Nangong Nayue did not dislike it.

Just as Saigō had said, she actually liked children very much. Otherwise, she would not have wanted to become a teacher.

At home, she took excellent care of Aurora and the others as well.

Though she often ordered Aurora and the others to do this and that, Nangong Nayue sincerely regarded them as her children.

She was like a strict mother. Though her words were always merciless, the tenderness in her heart gave Nangong Nayue a peculiar feminine charm.

At night, dark clouds obscured the moonlight. At the Foundation Gate on String God Island, members of the Artificial Island Management Corporation were holding a meeting.

They had no idea that the demon's slaughter was about to descend.

The Sins of Demons and Witches

Inside the Foundation Gate, in the conference hall of the Artificial Island Management Corporation, many people dressed in suits sat in a circle.

Most of them were middle-aged men over forty, though there were also several elderly men.

These people were the true rulers of String God Island—a group of capitalists who sucked the people dry.

"The news from Gozo Island has been verified. The demon contracted to Nangong Nayue devoured the Cursed Soul there and took control of the Vessel of the Night Lord of Blazing Light."

At that moment, a potbellied middle-aged man looked around the room, holding a report in his hand as he spoke slowly.

Someone among the others gathered around the conference table said, "...So that means the demon contracted to Nangong Nayue now possesses the Fourth True Ancestor's Familiars?"

"Precisely!"

"How did It do that? The Cursed Soul was one of the Celestial Tribe's greatest technological creations. For thousands of years, no one has dared to clash with that soul in the domain of souls."

"...Yet that demon completely devoured it and obtained the Fourth True Ancestor's power."

Someone voiced their disbelief.

"Who knows? Perhaps it is a secret unique to demons. The demon contracted to Nangong Nayue is unlike an orthodox demon to begin with, so it is only natural that It possesses its own peculiarities."

The middle-aged man who had delivered the report said with slight hesitation.

"There is no need to concern ourselves with how that demon devoured the 'First One' for now. What we should consider is what impact this will have on String God Island and our objective."

An elderly man with a head of white hair tapped the table as he spoke.

His words temporarily quieted the noisy conference room.

The middle-aged man giving the report continued, "...Looking at the outcome, this should be good news. We are all on the same side here, so I will speak frankly."

"...The families and corporations represented here chose to fund Kagami Chiro's construction of String God Island for only one purpose: the altar of Sin God Cain and the Great Calamity system."

"However, due to interference from the Sanctuary Treaty nations and the other three True Vampires, despite our occupation of String God Island for so many years, our research into Holy Annihilation has made no progress."

"...But now, an opportunity has arrived. The Fourth True Ancestor—the world's strongest vampire, said to have no blood relatives or followers, to stand alone, seek no dominion, and merely command twelve incarnations of calamity."

"As long as we can gain control over the Fourth True Ancestor's power, we will have the means to contend with the other three True Vampires and the Sanctuary Treaty nations."

"...This will create an excellent opportunity for our Holy Annihilation research. As long as we can master the power of Cain's Great Calamity, the world will be within our grasp!"

"Now that the Miko of Cain is under our control, we can attempt to activate Holy Annihilation at the appropriate time!"

The speaker's words made the many String God Island administrators present nod in agreement.

Someone asked, "...Then how are we supposed to make the Fourth True Ancestor's power serve us?"

The white-haired elder smiled. "...That is simple. The Witch of the Void has entered into a contract with a demon, and her true wish in that contract is 'Peaceful Coexistence Between Humans and Demons.'"

"...To fulfill that wish, she must have String God Island's support. She certainly will not betray String God Island."

"All we need to do is give her a promise. Promise that once we seize this world, we will work toward fulfilling her wish. The Witch will surely obey our orders."

"...And according to our investigations over the past few years, the demon hidden within the Witch's shadow is like the guardians of other Witches. It seems to have no excessive ambitions and has always kept to itself."

"I imagine It will also allow us to make use of the Fourth True Ancestor's power in order to fulfill the contract!"

The elder's words won the approval of everyone present.

So what if they were ordinary people? As long as they controlled wealth and power, as long as they grasped the weaknesses of others, they could command the strong and make them serve them.

This was precisely the arrogance and prejudice of these people. Even Witches and demons were to be exploited by them, treated as tools for their use.

"Then should we help that demon obtain the other Vessels now, so that the Night Lord of Blazing Light's power can fully emerge?"

"Of course. I believe that is necessary."

"I second it!"

"I second it!"

"..."

The group raised their hands to vote. Everyone looked relaxed, even faintly excited, as though they could already see their success and the world about to submit beneath their feet.

"Though I appreciate your desire to help me seize the other Vessels, I think it is better to handle my own affairs myself."

"...If I had to trouble others with everything, would that not make me seem far too incompetent? Don't you agree?"

At that moment, a leisurely yet somewhat gloomy male voice echoed through the conference room.

The many String God Island administrators present changed expression. The white-haired elder slammed his hand against the table and barked, "...Who is it?"

Though his voice was stern, it carried an air of bluffing.

The conference room erupted into chaos. None of them had expected anyone to infiltrate the heavily guarded Foundation Gate.

"Allow me to introduce myself. My name is Zarathustra, the demon you spoke of—the one contracted to the Witch of the Void."

"...Oh, right. I am also the target you intended to exploit."

Saigō chuckled. Accompanied by a burst of black flames, his figure appeared in the center of the conference room.

Within the Foundation Gate, especially in this meeting site of the Artificial Island Management Corporation, a barrier had been established to prohibit spatial transfer.

But what Saigō used was not this world's Space Control technology, but magic from the World Tree.

The previous dynasty's sword could not behead the current dynasty's official.

They were fundamentally different systems, so the barrier here naturally lost its effect.

It was not that Saigō could not use World Tree magic. It was merely that its magic was of little use against truly powerful beings, so he rarely used it.

"Demon, why are you here?"

The white-haired elder asked, forcing himself to remain calm.

"I have only one purpose, of course—to kill you all!"

Saigō wore a gentle smile as he spoke those incomparably cruel words.

The expressions of everyone present changed drastically. Someone shouted in panic, "...Security? Where is the security team? Get in here and protect us!"

"Bang..."

The doors to the conference room flew open, but what entered was not String God Island's security team. It was a nauseating stench of blood.

Three doll-like beautiful girls with rainbow-colored hair and Flame Light Eyes walked in together. Behind them, the corridor was a complete mess.

The corridor walls were smeared with thick, bloody gore. Severed limbs and the terrified expressions of dying humans came into the sight of the many Artificial Island Management Corporation members present.

Their legs trembled. Some were so frightened that they soiled themselves, while several younger people spoke through tears:

"...D-Demon sir... Mr. Zarathustra, w-what do you want? We can give you anything. Please, please don't kill us."

The group that had been so high-spirited moments ago, planning to control Witches and demons, now revealed their true colors.

"I do not need you to give me what I want. I will take it with my own hands... because what I want is your lives!"

Saigō said with a smile.

The elder's lips trembled as he asked, "...Demon, does Nangong Nayue know you are doing this?"

Saigō revealed a surprised expression. "...What gave you the mistaken impression that I, a demon, have to listen to a Witch?"

"...You should know that it was the Witch who sold her soul in exchange for a demon's power. If anyone is to obey, then it should be the Witch obeying the demon!"

Then Saigō's smile faded as he addressed the three Vessels of the Night Lord of Blazing Light. "...Kill them all!"

Aurora and the others obeyed Saigō's command. Even without summoning their Familiars, they were vampires with immense magic power. Killing these ordinary people was simply too easy.

"Please, don't kill me."
