Crossover Anime: A Dimensional Journey Starting with Frilian

"Teacher, what exactly does La Fria mean?" Yukina Himeragi was unhappy, so she got back to the point.

“Okay, La Fria is right. What I didn’t do was actually what I did,” Shichen confessed.

"That sounds so convoluted..."

"It's very simple. Someone wants to do something to Nagatsuki, but I plan to tacitly allow them to do it."

"Huh?" Himeragi Yukina finally realized what was happening and was surprised.

"Teacher, do you mean you're going to let others attack Teacher Nangong? Don't you like Teacher Nangong?"

"It was precisely because I liked her that I allowed others to make a move on her."

"What do you mean?"

"That month, she refused to let me free her."

"Freedom?" Yukina Himeragi still didn't understand.

“I have a clue about this. Chen, what you're talking about is probably the prison barrier, right?” La Fria asked.

The prison barrier is a sealed space different from this world, an eternal place of exile, a time labyrinth with no exit.

"Prison barrier? Isn't that an urban legend?" Himeragi Yukina asked.

“No, the prison barrier does exist, it’s just invisible.” Shi Chen shook his head.

"So, what you mean, teacher, is that the prison barrier is related to Teacher Nangong?"

"Yes, that moon is the guardian of the prison barrier."

The prison barrier is an artificial alternate world created using the power of the dragon vein flowing through the Demon Realm. Its existence is invisible, and even the council members who created it do not know its exact location.

But it does exist, and it is located somewhere in Itogami City.

Even the artificial island management commune cannot confirm who sent the prisoners into the interdimensional prison in the area, or how.

The answer came to mind immediately.

"So, what you mean, teacher, is that the prison barrier is related to Teacher Nangong?"

"Yes, then Yue is the guard of the prison barrier." Shi Chen nodded calmly.

Nangong Nayue is the Void Witch. She is the guardian, gatekeeper, doorkeeper, and key of the prison barrier. Basically, the prison barrier is the name of the magic used to seal away evil demons and guide criminals, and she is the only one who can use that magic.

Because the prison barrier is maintained by magic that Nagatsuki uses, her true form remains inside the prison barrier.

The term "witch" is another name for a woman who has made a pact with a demon. By acting as a guardian of the demon's servants, she can use the same power as the demon.

Witches possess human bodies and can wield magical power comparable to high-ranking demons. Their magical abilities even surpass those of the highest-ranking mages. However, making a pact with a demon comes at a price.

The price Nangong Nayue paid was to remain sealed in that huge, empty prison, all alone, until her death.

This is the curse she suffers, just like the True Ancestor.

Nangong Nayue was initially willing to take Shichen in for this reason as well; she and he were kindred spirits.

"Nayue's true form has always been inside the prison barrier. She has lived there all her life, and has never been outside since ten years ago. She has always been alone there," Shichen said calmly, describing Nangong Nayue's situation.

“Wait, isn’t that strange? Nangong Nayue has been here all along, hasn’t she? I saw her yesterday.” Kirasaka Sayaka couldn’t help but speak up.

“I think that’s Sister Nangong’s clone, right?” La Fria asked Shichen.

"Yes, the moon you saw was an illusion created by her true self using magic. It was just... a dream of the sorrowful girl who stayed there."

“Illusion, illusion… how could it be… no, if it’s her…” Himeragi Yukina denied herself.

When she thought of Nangong Nayue's identity as a witch, and her extraordinary abilities... creating a physical clone and disguising it as an ordinary person would indeed be a piece of cake for her.

This also explains why Nangong Nayue can remain young and never grow old.

"Is someone targeting Teacher Nangong in order to release the criminals from the prison barrier?" Himeragi Yukina asked again.

Although she didn't understand the prison barrier, urban legends clearly stated that the prison barrier was a place where magical criminals were imprisoned.

Now that the prison barrier is real, the prisoner detention area must also be real.

"more or less."

"almost?"

"It's pointless to destroy that moon's phantom unless the seal of the barrier is broken, allowing her true self to return to this world... The criminals in the prison barrier are imprisoned in her dreams. Destroying her will free those prisoners."

"Wouldn't Teacher Nangong be in great danger? Teacher, how could you... wait, Teacher, you wouldn't be...?" Himeragi Yukina said halfway through, then suddenly realized what Shichen meant.

"That's right, I want those people to release Nagatsuki and let her return to this world."

“Teacher, you…” Himeragi Yukina couldn’t speak.

She didn't think there was anything wrong with her timing, or even that she was right. Nangong Nayue was indeed pitiful, being all alone in the prison barrier.

But what will happen to the criminals if she is rescued?

Those were all unforgivable, heinous criminals.

"Yukina, I know what you're worried about, but have you forgotten who I am?"

"A teacher's identity... Ah!"

"Teacher, I am the Fifth True Ancestor, who could never possibly exist. I will deal with all those criminals when the time comes."

“No wonder the teacher just let it go.” Himeragi Yukina sighed helplessly.

“I’ll even help.”

"Huh--?"

“Chen, I have a question. With your abilities, you should be able to easily get Sister Nangong out, right? Why don’t you do it yourself? Now that someone is watching her, won’t something bad happen?” La Fria asked doubtfully.

"I could easily rescue her, even if it's the Demon July, I could handle it, but she doesn't want to come out." Shi Chen helplessly spread his hands.

"Unwilling? Why?"

"I'm not sure either, so this is all I can do."

"No wonder......"

"You don't need to worry about Na Yue being in danger. I said I would help those people, so I will definitely keep an eye on them and not let them hurt Na Yue." Shi Chen smiled faintly, but his eyes revealed a coldness.

"Sendouki Yuma, hurry up and come."

"Huh? Sendou Yuuma? Isn't that Akatsuki-senpai's friend?"

"It's her."

Chapter 462 The Power of Familiars

"Sister, why is this city still so ugly?"

At night, on the sea off Itogami Island, two people were walking on the water.

The voice belonged to a woman in red. Her revealing outfit had the flair of an exotic dancer, with provocative stockings and a long hood reminiscent of a magician's robe, all in a deep, blood-red hue.

She appeared to be around twenty years old, and judging by her clothing alone, she could easily be mistaken for a prostitute. However, the fierce aura emanating from her made people hesitant to think too much about her.

The woman is a witch, and there is a danger of her making a pact with a demon.

“Yes, it really is ugly,” came a seductive voice in response.

The owner of the voice was dressed entirely in black. She wore a wide-brimmed triangular hat, a dark black cloak, and a tight-fitting black leather motorcycle suit that covered her entire body completely.

Her curvaceous figure was perfectly outlined, and her alluring curves were on full display. She might be even more attractive like this than if she were naked.

She was a witch too.

Crimson Witch and Dark Witch.

Just as the two stepped onto Itogami Island, the blinding beam of a searchlight suddenly enveloped their figures.

Immediately afterwards, fully armed mobile units were deployed along the coastal roads.

"Ugh, what a downer, sister." The crimson-clad beauty sighed disdainfully as she glanced at the security guards.

"Yes, it's a reunion after ten years, why can't we be given a more grand welcome?"

The two whispered amongst themselves, their arrogant attitude showing no regard for the security forces.

"Warning to intruders: You have violated the administrative area of ​​the Demon Realm. We will detain you in accordance with the Special Zone's security regulations. Immediately remove the magical barrier and heed our advice!"

The captain of the guard shouted a warning, but the two beautiful women remained unmoved.

"You only have ten seconds. This is your final warning. If you do not comply, we will take strong measures to detain you."

The guards pointed their weapons at the two men.

The two beauties simply laughed coldly at this.

"Why are these ignorant people so noisy?"

"Hehe~ Try your best to please us."

Ten seconds passed in the blink of an eye, and the security team attacked the two men without hesitation.

"Fire!"

Sparks burst in the darkness, and countless gunshots merged into one, deafeningly loud, yet the torrential rain of bullets did not touch the two witches at all.

The enormous tentacles that burst forth from the sea acted as their shields, blocking all the incoming bullets.

"what is that?"

"Monster?"

"Who exactly are those two people?"

The guard was horrified by the enormous tentacles, which were thick and long, and looked disgusting and creepy. Their semi-transparent appearance was reminiscent of the flesh of a cephalopod like a squid.

"Sigh, we're supposed to be residents of a city that's supposedly a special zone for demons, so please don't make such a fuss about a servant demon of this level," the Crimson Witch mocked again.

The dark witch sneered and curled her lip: "Don't even think about it, Octavia. This is the city where that ill-mannered little girl lives. How much knowledge and experience do you think these people have?"

"Oh right, then I can only kindly offer my help."

As the Crimson Witch spoke, she unfolded the book that had been tucked under her arm. She placed her palm on the book, and the words on the pages shone with light, surging forth with immense magical power.

"Next, I will use your blood to make this filthy city a little more beautiful."
