Otome Game Mob Villain

Chapter 585

"You know about the Roukyuuju (Prison Palace Jewel) I explained earlier, right? When it crystallizes, it always turns into a specific color."

"Don't tell me..."

I was startled by Sandra's suggestive tone, and she nodded with a serious expression.

"As you've guessed, all Roukyuuju are jade-green in color."

"Wait, but isn't it a bit hasty to assume that the 'jade-green orb' is modeled after the Roukyuuju just because they share the same color?"

I tilted my head, expressing my doubt.

I understand what she's getting at, but relying solely on the shared color as evidence feels too weak.

However, Sandra shook her head.

"Of course, it's not just the color. More importantly, it's the phenomenon you witnessed, Lord Lidd, where it absorbed someone else's magical power."

"Uh, what do you mean?"

"I looked through various historical records, and I found almost no instances of a phenomenon where someone's magical power is absorbed. However, if I had to name something similar, the mechanism of the 'Prison Palace' (Danjon) is the closest."

"Ah..."

I finally grasped the meaning behind Sandra's words.

The Prison Palace Core accumulates magical power over long periods, using that power to create the Prison Palace and monsters.

In other words, it releases the stored magical power.

Moreover, it has the property of 'absorbing' the magical power of those who wander into the Prison Palace, allowing it to grow further.

Thinking about it, it's similar to the phenomenon where Gabriel transformed after absorbing the jade-green orb.

As I was left in stunned silence, Ellen interjected, "This is just an additional note, but..."

"The armor we created for Lord Lidd also has the property of absorbing or releasing magical power. This was made possible by utilizing the characteristics of the Roukyuuju."

"Exactly. And most magical tools, to a greater or lesser extent, have the ability to absorb or release magical power. The primary material used in their creation is the Roukyuuju."

"I see. So that armor also uses Roukyuuju, huh?"

A rare gem imbued with high magical power, and also used as a material for various magical tools—the Roukyuuju.

In my memories from my past life, there was no such thing in 'Tokirera.'

It's possible that the item names in the game are different, but I don't recall anything similar either.

If there had been, I would have moved to secure it immediately.

"There's one more reason we assumed it was modeled after the Roukyuuju."

"Another reason...?"

As Sandra said this, Curtis cleared his throat.

"To be honest, in Renalute, there are fairy tales about people who went missing in the Prison Palace suddenly appearing in towns or countries, bringing disaster with them."

"Wait, but Sandra said she couldn't find anything like that in historical records."

When I glanced at her, she shrugged.

"To be precise, it was in the Empire's records. I couldn't possibly investigate all the fairy tales in Renalute."

"Ah, I see."

In this world, without something like the internet from my past life, knowledge is only accessible through books.

That said, a book compiling fairy tales from various countries would probably be too niche to exist.

"Well, it's probably just a cautionary tale to keep children away from the Prison Palace. However, in the fairy tale, the person who brought disaster to the town was said to have devoured people one after another. It reminded me of this incident."

Curtis said this and bowed slightly.

"I see."

Fairy tales are usually based on some kind of real event.

And when you consider Gabriel's transformation, the jade-green orb, and the properties of the Roukyuuju, it all seems to connect.

"Everything we've discussed is just a hypothesis based on the information we have. Without concrete evidence, it remains speculative."

My father spoke up, his eyes sharpening.

"But it's better to act with a hypothesis in mind than to act without thinking. If we're wrong, we can adjust. In any case, don't let your guard down in the Foxkin territory."

"Understood."

With my bow, the meeting concluded.

By the way, since it was a good opportunity, I explained the Demon Blade Technique to my father and demonstrated it in the training grounds. He seemed to like it, saying, "Hmm, this seems like a useful technique," without getting angry.

Come to think of it, I recall that my father wasn't particularly skilled in spear-based magic either.

"I'll allow you to teach Rubens and Asuna. But first, teach me."

"Wait, you want me to teach you, Father?"

"Yes. Since Rubens deemed it a good technique, it might eventually be formally adopted by the knight order. Therefore, I should be able to use it first."

"Uh, huh. Formally adopted by the knight order? I don't think it's that impressive of a technique, though."

The conversation had escalated beyond what I expected, and I was taken aback, but my father seemed unusually pleased.

However, Kiel's words suddenly flashed through my mind, filling me with unease.

"May I ask something unrelated?"

"Hmm, what is it?"

"If the Magic Blade Technique is formally adopted by the knight order, you're not planning to use it to dominate the world or anything, right?"

"Of course not. Wait, don't tell me..."

My father looked exasperated but quickly turned stern.

"Are you hiding something again? Or are you plotting something nefarious?"

"W-what?! N-no, of course not!"

"Really? You're absolutely sure?"

For a while after that, I was under my father's suspicious gaze, and it was quite a hassle to clear up the misunderstanding.

Incidentally, my father mastered the Demon Blade Technique in just a few days and quickly became more proficient with it than I was.

He mentioned that in the near future, he might consider formally adopting it as a technique for the knight order.

I didn't think it was that amazing of a technique, though.

After my father mastered the Magic Blade Technique and gave his permission, I was able to teach it to Rubens and Asuna as well.

Both of them mastered it within a few days and are already better at using it than I am.

After my father, Asuna, Rubens, and I tried using it, it seems that the  Magic Blade Technique is closer to a 'body enhancement' type of magic, where the user's swordsmanship skills are more important than their magical power.

Even I, the creator of the technique, was quite surprised by this revelation.

Currently, my father is the most skilled at using the Demon Blade Technique.

Even though I'm the one who created it...

And so, while teaching the Demon Blade Technique to my father and the others, I spent my days catching up on the administrative work that had piled up during my time in the Foxkin territory.

Before I knew it, the day for my return to the Fox tribe  territory was fast approaching.
