Trinity Seven Prophecy

"So the problem is that the principal who is one of the Heavenly Arbitrators and the people in his group who have the task of keeping the world in balance have gotten a prophecy about the "Goddess of Darkness" who will rise again and end all the worlds in your universe."

"For that reason the principal who happened to find a way to arrive in this world had the idea to ask for help from outside and that's why you were sent to seduce me, Lilith?"

Eiji asked Lilith who had just finished explaining why she was asking for his help to save her world.

They had stopped joking and the atmosphere in the room became serious.

Rias and the other members of the occult research club were confused because they were completely unfamiliar with the Goddess of Darkness that Lilith mentioned. At most they only knew there was the famous God of Darkness Erebus from Greek Mythology and that man was now dead at the hands of Eiji. He also had a younger sister, the Goddess called Goddess of Night Nyx and now that woman was a maid in Eiji's house.

But Lilith said it was her universe, so it must be a Goddess from another world.

Eiji wasn't really familiar with this "Goddess of Darkness" either, but then he remembered a novel cover featuring a silver-haired woman who had Heterochromic eyes: blue and red.

He tried to dig his memories from his previous life further and managed to get a little information about her.

The Goddess of Darkness called Lilith is the boss villain in the Trinity Seven franchise! In Highschool DxD's power system, this woman's full power is probably on par with beings like the Great and Trihexa or even the ExE gods because she can assimilate all dimensions.

Instead of being slightly scared or very serious, the corners of Eiji's lips lifted, his eyes sparkling for unknown reasons.

Miss System and Leme who knew what their host was thinking were silent. Should they say it? Given Eiji's personality, what he was thinking when recalling the Goddess of Darkness' appearance was not surprising.

[As expected of my King! So what if it's the villain boss? She's a very beautiful woman!]

Leme... What are you saying? Don't say things that will make people misunderstand.

[.....]

In contrast to what he thought, on the surface Eiji made a serious face.

"Yes the power of the Goddess of Darkness is too strong that in the past, the combined Heavenly Arbitrators and the strongest mages in various worlds were unable to kill her and could only seal her away."

"Many years have passed since then and I only know this story from the principal and the books that recorded about that creature."

Lilith explained how powerful the so-called Goddess of Darkness was in a way that was easy to understand as she considered Eiji and the others who were from another world.

"I'm sorry but who exactly is this Goddess of Darkness you're referring to, Lilith?" Still, Rias didn't understand.

Lilith thought it was natural and added with an apologetic expression. "Her name is Aryan Celestial. She is a True God who is also known as the Goddess of Darkness. I don't know how gods are in this world, but in my world Gods are extremely high dimensional conceptual existences. They have unlimited magical power and one Thema..."

She also began to tell everyone in the room what Thema was. It was different in this world where people could use magic as long as they mastered spells and had enough magic power, demonic power, holy power or other energy to do so. In Lilith's world people had to choose their theme first before going down the path of magic.

It all starts with the seven archives known as the Seven Deadly Sins: Superbia (Pride), Ira (Wrath), Acedia (Sloth), Invidia (Envy), Avaritia (Greed), Gula (Gluttony) and Luxuria (Lust) which hold a wide variety of themes related to each archive. In the battle against Hades that destroyed the entire Realm of the Dead, Eiji had used one of the magic related to the Superbia archive. Lilith didn't know this, if she did she wouldn't doubt the boy's power.

But put that aside.

From Lilith's explanation, Thema made magic more complicated because one had to have a theme that was opposite to their personality. In short, your theme is the furthest thing from yourself. So the things that are further away from one's common sense are what make "magic" materialize. Most people will choose Archives and Themes that are opposite to their personality, because that seems the easiest for them to use since magic is inherently irrational, in other words, they have to think in a way that is opposite to themselves.

Of course not only that, they also had to do research to understand their archives and themes.

Eiji had Judecca, he didn't have to bother thinking opposite to his perverted self and being a herbivore... cough, he just needed to choose the archives and themes recorded by that Demon Lord Weapon and master them quickly using the understanding of magic that Anos and Varvatos had.

While Rias and the others were enlightened by Lilith's explanation of the power system in her world.

Eiji suddenly remembered something, although he already knew, he smiled and asked. "I see, Lilith. By the way what is the theme that Aryan-, that Goddess of Darkness, has?"

"...." Rias and the other girls narrowed their eyes suspiciously when they heard Eiji call out the Goddess of Darkness' name in quite an intimate tone.

Although the other party was basically a person feared by the people in Lilith's world. This man didn't think of her as a woman he could usually seduce, right?

Lilith who hadn't known Eiji as much as the girls in the room didn't think there was anything wrong.

"According to the records of the Great Magic War in the past where many people fought against the Goddess of Darkness, her theme is Evil. While the archive is not clearly known but it might have something to do with Ira, Avaritia or Invidia."

Eiji honestly didn't care about the Goddess of Darkness' theme and archives because he had the confidence to defeat her in some way and asked again with 'curiosity' on his face.

"And what about you, Lilith. What are your themes and archives?"

"I-It's..."

Lilith avoided Eiji's gaze. The gazes of Rias and the others didn't help either, making Lilith blush with embarrassment.

She seemed as hesitant to answer as when asked about her answer about Eiji's confession.

"Ara Ara. Lilith-san, I want to know too."

"There's no need to be embarrassed to tell us, Asami-san."

Akeno and Rias urged for an answer from the red-haired girl.

Ignore Yuuto and Gasper. Koneko bit her lip, she lowered her head to hide her lewd expression that would make people surprised.

Her petite body trembled slightly, she really wanted to meow. Because Eiji didn't just use one finger, during the conversation he slowly inserted three fingers.

Koneko was almost crazy, especially when the man's hand had a magical effect that made her hole feel electrocuted. The pleasure she felt was also more than enough to make her breathless.

"Can we skip this question? It's not important, right?" Lilith didn't want to answer because she was too embarrassed to say it.

It was fine if these people didn't know how magic worked in her world yet, but now they did! She herself explained it to them!

So they could roughly guess how her magic worked from the theme name and the archives.

"Lilith, how could this not be important? Have you ever heard the saying that before knowing your enemy, you must know your ally?"

[Isn't what you said backwards, host?]

"Not yet." Lilith said.

Eiji sighed, he ignored Miss System and said seriously. "Lilith, tell us."

Lilith complained in her heart why is Eiji so pushy about this?! He was forcing her to answer this question more than answering about his confession...

Rias and the others except Koneko who was having trouble thinking properly were getting curious.

Lilith's reaction was a bit excessive, right? Isn't it just the name of the theme and the archive?

Why is she—

"My themes are Abies, Fall, and Vanitas... All from Luxuria..." Lilith whose face was flushed red said in a very small voice

"Lilith, what are you saying? Please say it louder, we didn't hear it." Eiji pretended not to have ears that could hear sounds within a radius of tens of meters.

The devils in the room could also certainly hear Lilith's voice. But they were silent and pretended like Eiji.

"I said that Lux... Ugh! My T-Theme is basically Luxuria!" Lilith shouted. Now she had the urge to find a quiet place and squatted down while covering her face.

Rias and the others were dumbfounded.

Akeno giggled. "Luxuria? Doesn't that mean the theme Lilith-san chose was Lust? That fufufu was unexpected~"

"From your explanation earlier, Asami-san. A person who has chosen a theme must of course study the theme as well. That means that even though you don't like perverted things that are contrary to your personality, you have learned a lot to perfect your magic."

Rias said an analysis that made Lilith even more embarrassed.

And at this moment, Eiji's inner voice asked an outrageous question.

[Wait, is Lilith still a virgin?!]

"No, even though I have experience, this newly created body is still a virgin."

In the house of Eiji, the devil ancestor, Lilith who was enjoying watching DevilTube from the laptop while sitting on the living room sofa unconsciously answered.

That man, Eiji kept calling her name over and over again.

Although she knew it was the name of another woman similar to her, she could sometimes misunderstand.

"Lilith, the Lilith Eiji is referring to is probably Lilith Asami whose appearance is somewhat similar to Rias."

"Is that so? Still, should I change my name so that others don't misunderstand?"

Lilith looked at the silver-haired maid who was cleaning the carpet with a vacuum cleaner not far from her.

Grayfia was silent for a moment before saying, "Don't do that. You're the mother of all devils, at least have the dignity to defend your own name."

Since becoming addicted to technology, the woman who could be considered her ancestor often laughed to herself when she watched DevilTube videos and played online games. Sometimes she was also very quiet when reading random articles on the internet, she seemed to be enjoying herself so much that her image as Lilith who was the mother of all devils was not visible at all.

Grayfia didn't know if this was good or bad, but at least this woman wasn't as depressed and suicidal as before.

Back to the occult research club room, at the same time.

"D-Don't misunderstand me! I'm still a virgin, okay?"

"Although I did learn many things related to my theme, I learned them from books and the internet!"

Lilith frantically defended her innocence in front of everyone, especially Eiji who was wondering whether or not she was still a virgin in his heart.

How could this man be so focused on such a sensitive part?

She hadn't even dated anyone yet.

Still, Eiji looked satisfied hearing her answer which made her snort and resist the urge to shoot him.

This man...! Why does he care so much about my virginity?

Lilith actually already knew the answer, but she wasn't ready.

She was relieved to hear that Eiji's mind was no longer on her virginity.

[In the original work, the plot about the resurrection of the Goddess of Darkness feared by many in the world of Trinity Seven certainly existed.]

[However, since Biblia came to this world and wanted to ask for my help instead of relying on the protagonist who has the potential to become the strongest Magic King. The plot moved faster and changed! Lilith was even sent to seduce me to help the people of that world to fight against the villain boss who was about to rise.]

[This... Gosh, why are these people relying on me? I'm not the protagonist! But fine, I remembered a bit of the plot and knew how to prevent the resurrection of the Goddess of Darkness. For the sake of Lilith and the girls in Trinity Seven... I mean the lives of the innocent people in that world. I'll do it!]

The heroines:

[Mio: Do what? Are we still talking about saving the world?]

[Yuki: Eiji mentioned Lilith and the girls from Trinity Seven before those people so...]

[Mai: His intentions are good and cool like a good protagonist but why do I feel like there's more to it than that?]

[Sona: Ahem! Girls, I know you're smart but just pretend to be stupid, okay?]

[Ai: It's Eiji after all.]

[Maria: As expected from Eiji-san!]

[Sapphire: What is this guy doing?]

[Venelana: Fufu. Sapphire-san, you don't have to worry about what our young husband is doing. Instead of that, why not come to his house to have tea with us?]

[Sapphire: I'll be right there. I happen to be upset because Jin has been bothering me a lot lately even though I've made it clear that I no longer love him the way I used to.]

[Yasaka: Hurry up and discuss it with us.]

While the adult women made an appointment to gossip at his house, Eiji didn't know and said to Lilith who was now looking at him with a moved expression.

"Lilith, I don't know if my power is enough. But I'll try to help you."

"Eiji..."

[Lilith Asami +6]

"...." Rias and the other girls. Seeing Lilith's expression that looked like a girl in love whether she realized it or not, they knew she couldn't be helped by the protagonist anymore!

If the protagonist of the original work is here, he might panic?

...

In the library of the Royal Biblia Academy.

The protagonist of Trinity Seven, Arata Kasuga is training hard to become stronger so that he can save his cousin, Hijiri and prepare to face a multi-dimensional level disaster.

The last one is about the resurrection of the Goddess of Darkness. Apparently this has something to do with the principal sending Lilith to seek reinforcements in another world.

At least that's what Akio told him yesterday.

Arata realized the seriousness of this matter. Even though he had only been studying magic for over a month and didn't even know how powerful the Goddess of Darkness who was the boss villain in his world was. He had a sense of urgency to become the King of Magic as soon as possible!

However, while he was so excited to read the magic books in the library that could deepen his knowledge about the theme and archives he chose.

Suddenly, he clutched his chest as he felt someone stole something important from him. It didn't hurt, he just felt uncomfortable.

It was the same feeling he had before being hit by Akio's kick. The difference was that this time the feeling was stronger.

"Yo Master, do you have a history of heart disease?"

"Hmm... I'm sure not."

"Then?"

Hearing the question of his legendary gremoir, Astil Manuscript or commonly called Sora who was now in the form of a gremoir around his neck. Arata scratched his head with a confused expression.

"I don't know. I'm not sure either..."
