No Fatigue: 24-jikan Tatakaeru Otoko no Tenseitan

Outside the stables, from the royal dwellings, we heard a tremendous explosion.

How awesome the sound is, so much so that everyone who was on the spot nodded holding their ears.... Naturally, my ears have been keen on the unintentional explosion, too. This is probably because the castle corridor that leads to the residents sounds so well that the explosion sounds amplified.

... not if you're analyzing it in a swallowing way!

I stood up and tried to make my way to the explosion - I grabbed my arm from behind and relaxed.

"Wait, Edgar. It's okay."

That's what Brother Berhardt said when he grabbed my arm with his other hand, holding his ear with one hand.

"Did you do it again, Irvara guy!?"

Prince Ilfreed yelled so loudly, rushing towards the explosion.

All who were on the spot somehow follow the prince.

"Irvara! Are you all right?"

It was in front of the blown door that Prince Ilfreed shouted so.

"Keho Keho...... so, it's ok...... brother"

A young woman in a dress crawled out of the door coughing.

Coal is all over the dress that looks expensive. No, that's not all. That's...

"Keh, blood stains......?

Blood stained the work apron on top of the dress, which was extremely out of place.

"Hih, princess!

A maid jumped out of our backs.

The maid is a "princess" - when she approaches a woman full of coal, she uses handkerchiefs and brushes to pay for the coal.

Someone in a row coughed up at the sprinkling coal.

The maid looks back and says, bowing her head again and again.

"Sorry! The princess will call for a new order, so will you please leave the room once you have done so?

"Oh, oh...... Guys, I'm sorry, but let's get out of here."

Prince Ilfreed urged him to leave together while being taken lightly.

Eventually the other maids will fly away and lead us to another room.

Four of them, Prince Ilfreed, Prince Ellens, me and Brother David, thoughtfully table in the guided reception room. It should be noted that only Brother Berhardt is returning to the Dragon Knights stables, saying he will prepare for the regular sentry.

"... Not at all, it's a problem for Irvara"

That's how Prince Ilfrid spills it.

"You're making a scene every time."

Prince Ellens also agreed with Prince Ilfreed, shrugging his shoulders.

"Um... weren't you hurt? There was blood on it."

That's what I ask.

If you have a few injuries, you can heal them with [healing magic], so if you don't have any other manpower, I'm going to help.

Most of all this is a royal castle, so there will be about [healing magic] users.

"Oh, you'll be fine. It explodes flashly every time, but he doesn't get hurt wondering."

"Originally, [the spell] is not magic that can produce a large output instantaneously, is it? Explosion doesn't mean the Fireball will burst."

Two princes said that to their mouths.

I was intrigued by what Prince Ellen said.

"... [spell], is it"

"Oh, are you interested? Then you should ask him later."

That's what Prince Ellens said, and the door to the reception room was knocked.

- I brought the princess.

Prince Ilfreed responds to the voice heard from across the door, "Let him in".

What emerged from the open door was a woman in a dress about twenty years old.

Brunette's hair looks great in a smeared dress, a beauty with a flamboyant vibe. It has a slightly shady face, but depending on who sees it, it will sometimes be fascinating to see there.

... I don't think he's the same person who was covered in coal earlier.

"... I showed you something ugly earlier..."

Woman - Princess Irvara said that in a whispering voice with her eyes down.

Even though my voice is beautiful in itself, I think I'm losing a lot of money on the way I talk.

"I don't mind. I just wanted to say... I was just showing my guests around, apologize properly."

"… Guest, is it?... oh...?

In the words of Prince Ilfrid, Princess Ilbara sees Brother David and me as she first noticed.

"... Mr. David?

"Hello, Princess Irvara"

Sounds like the princess knew about your brother.

Brother David let her thank Princess Irvara as she did.

"Oh, did David know your sister?

That's what Prince Ellens heard.

"Yeah. I worked as a clerk, and I've helped you with your research."

"... that verse, thank you very much for your help..."

"No, even for me, I have had a meaningful time, touched by the princess's insights"

"... my goodness, compared to Mr. David..."

Princess Irvara seems to have lit up and leaned even further down her leaning face.

"... I didn't expect to see you here... that's unusual... What can I do for you...?

"No, unfortunately. I came today to visit His Royal Highness, Ellens."

"Sorry to hear that, David."

To Brother David, who answered Princess Irvara, Prince Ellens tells him to make fun of him.

"Not at all. I believe you have received an honorable assignment."

"I'm sorry, it's about my father, didn't you approach him pretty forcefully?

Prince Ellens treats Brother David quite comfortably.

Speaking of which, I thought you said you had an interaction with the prince on the hospital bed about the library book.

Brother David seems to be committed to responding with no disrespect, sometimes because the other person is a prince. Is that a little different from the relationship between Prince Ilfreed and Brother Berhardt?

"That's not... I and Edgar were also concerned about the Ripper trend."

"... Ripper, is...?

Princess Irvara picked up Brother David's words.

"This time, in the form of assisting Prince Ellen, we're going to be investigating the Ripper."

"Really... by the way, that... ripper, is that...?

"Eh."

Rarely, Brother David is vegan and surprised, but I can't tell you about people either. I said "eh" at the same time as your brother.

And what is surprising is that both Princes Ilfreed and Ellens were with them.

"Oh hey Irvara...... I don't think so, but you don't know the rumors about the cleaver (ripper)!?"

Prince Ilfreed said, shaking his mouth as a mess.

"... hey, was something wrong..."

"If you don't like it, maybe it doesn't really matter to you..."

"... I wonder if you don't know about the Ripper (Ripper) that's all we're talking about, sister."

Both princes stuck to Princess Irvara, confused by everyone's reaction.

In the end, Brother David will explain to Princess Irvara once again about the Ripper (Ripper) case and how Prince Ellens was to direct the investigation into the case.

"... was that what happened... sorry, I've been stuck in the lab for a long time..."

Princess Irvara said sorry.

Prince Ellens says with a sigh.

"Not at all... my big decision for my sister is without shape. Now that I'm a leader in [spell] research, I don't make enemies of magic research either.

Yeah, it looks like you're interested in your sister's research, Edgar.

"... what, is it true...?

"Oh, yes. I heard you were studying [the spell]"

Suddenly the story flew over here and I answered, slightly wandering.

"My father told you that he was a reincarnator because my sister is royal, too, right?

"... Yes. Very…… interesting…"

Princess Irvara stares at me while I'm hot.

"Yes, no, there was no magic in my world. It may not be very helpful for Princess Irvara's reference."

"... Still, knowing a different world is huge... because it means not being caught up in this world stereotype..."

Somehow, don't say something like Brother David.

Where Princess Ilbara said so, the reception room was knocked and Brother Berhardt glanced at her face.

"Prince, it's time"

"Oh, is that already the time?... I'm sorry, I have a regular sentinel coming up, so I'll let you out of here. David, say hello to Ellen."

"Ha. Yes, I did."

Prince Ilfreed slapped Brother David on the shoulder sitting in the chair and left the reception room with Brother Berhardt.

Prince Ellens is sighing and dropping off the look. Sounds like you're not good at it after all.

but Prince Ellens didn't drag it off and said to Princess Irvara.

"Sister, this is your opportunity, why don't you explain your sister's research to Devitt and Edgar? I have more time."

"Yes...? Then why don't you listen to me... and you can come to the lab...? Mr. David, Mr. Edgar..."

"Yeah, sure."

So we left the reception room and went back to Princess Irvara's lab.

◇

Princess Irvara's lab was a mess.

It's not just because of the explosion earlier. The trail of the explosion had been cleaned up by the maids while we were in the reception room, but there was also a bunch of books, a bunch of pieces of paper, bottles of medicines, animal bone-like stuff scattered in the other parts, and there was no place left for the princess, Prince Ellens, Brother David, when my four entered, to stand anymore.

"... sister, why don't you clean up a little? This. Then you don't know where and what?

That's what Prince Ellens said as if he was stunned.

The prince's attitude toward Princess Irvara is intimate compared to that toward Prince Irfrid.

It means we're both magic researchers, so I guess there's a part of the pulse that goes through.

"... I know where and what"

The princess said that a little out of her mind.

That was a classic excuse for people who couldn't even clean up their rooms in their previous lives.

I will test the contents of the room with this [Devil's Eye of Truth]. Oh, you see the rare herbs and grass roots in the textbook Grandpa Ganash gave me. That's just royalty, and just what's in this room is going to be worth it enough that it's going to have one house built.

"No, some drugs I'm buying out of the treasury, so I need to keep my inventory under control"

"... because the maid is making an inventory for me.... about getting in, though. And..."

"And?"

"... it would be a mess if it exploded anyway..."

"No, don't say it yourself."

Prince Ellens shrugged his shoulder like no treatment.

"So, what's the princess's research...?

That's what Brother David talks about.

"Oh, my sister's specialty is the study of [spells] using human blood."

"Human blood, is it"

My brother hammered Prince Ellens in his explanation.

"Yes. Of course you know about the two names" Blood Trail Princess "...

"It's... yes"

Blood Trail Princess.

I've heard rumors, too. Princess Irvara says she has numerous blood stains attached to the dress she is wearing because of her research into [spells].

I don't see the dress Princess Irvara is wearing right now because it was just summoned by a maid, but the princess was wearing an apron shortly after the explosion and there were numerous bloodstains on there.

"I once went out to a gardening party of noble ladies dressed as they were..."

"... I took off the apron properly, but it also came with the dress..."

"You're in a lot of trouble with the ladies graduating screaming. It was helpful because Marquis Sargastine's daughter managed to clean up the place, but there was no stopping the two names from spreading."

Are you referring to the daughter of Marquis Sargastine, a little bit of Senior Miriam? You put your face on those seats, too. My Culver family is also a Marquis, but sometimes my father doesn't like the social world very much, and I've hardly ever had a face for that hand event either.... Well, in my case, there's a situation where it's hard to get it out in public because of the difference in appearance and real age. Because of this, rumors that the Culver family has abominations are whispered among the nobles or not......

"Anyway, Edgar seems interested in studying magic at this age. So why don't you show me your sister's research?"

"Please"

As Prince Ellens said, I bowed my head toward Princess Irvara.

"... okay... maybe you won't be interested...?

The princess doesn't seem confident. Say no so, then start explaining.

"... do you know about [the spell]?

"Uh, only that I have that kind of magic skill"

"... right. [Spells] are also generally classified as magic skills..."

As I said, Princess Irvara took something like a card out of a pile of cluttered "things".

No, that's an undisputed card. It was a card for card games, which should also be called the cards of this world.

"... but there's a big difference between other magic skills and [spells]..."

"Differences, is it"

The princess handed me one of the cards.

I flip my card over and look at the back, but it looks like a regular card. The middle of the card was depicted with π (aqua) characters.

"... there's a [spell] on that card. I did the surgery... uh, three months ago. This is how we're going to unleash it.

Along with the words of Princess Irvara, the letter of the card glowed lightly. And a droplet floats on the surface of the card. [Demon Eye of Truth], who could also see magic, was sensing that magic had been activated on the card while being faint. Activated seems π (aqua), judging from the voices of the surrounding spirits.

"" This is... "

Me and Brother David haunted my voice without trying.

To our surprise, Princess Irvara looks a little satisfied.

"Normally, magic can only be activated in front of the operator...?

You're absolutely right. Normal magic can only be activated within the reach of the operator. Julia's mother's Firestorm, because the seed fire is produced at the hands of the surgeon.

Is the exception about [spiritual magic] and the magic of the sentimental system?

"But only [the spell] can be activated without having to be in front of the operator... No, to be precise, [the spell] is still something that activates in front of you, but you have an interesting personality that the effects of surgery fly across space and activate..."

When Princess Irvara uttered the keyword, the distance between me and Princess Irvara was a little over a meter away. Normal magic makes it difficult to activate more than a metre away.

"Furthermore, unlike other magic, time can be put between the activation of the [spell] and the expression of the effect….

In this way, [the spell] will have very different properties from other magic in terms of space and time… "

"Oh...!

Plain, but this is such a funny story.

"So even by using [the spell], you can install magic and activate it at whatever time you want?

"I can... maybe. Some ancient relics found from the ruins can instantly activate magic by 'using', but this may also be an application of [spells]......

Nevertheless, modern [spells] are quite ineffective, unlike the public image...... It's another dream to curse and kill the person you're after... Though I don't think I can use it to fight... "

This man, don't bother to say the negative side of his research.

It may be the type of person who is too humble and hates you rather than modest. That's what my colleagues in my previous life had.

"… I recently wondered if I could use the [spell] to communicate cryptographically…"

"In [the spell]... cryptographic communication?

When I asked the parrot back, Princess Irvara nodded.

"Yep... first, I'm going to use [spell] to create documents... I'm going to use special ink for this..."

"How special is that?

"It's usually as transparent as water, but the ink is that when magic passes... I developed it..."

"That's amazing"

"Kufu...... thanks......

But that would only be the seed of magic......? I have improved this ink to discolor only when certain magic powers are sent in [the spell]...

What is the use of this ink... Do you understand, Mr. Edgar...?

I thought about it for a second and then I answered....... while trying not to think about the princess and other inclusive laughter called "kufu".

"… so, is it cryptographic communication? Use [spells] in anticipation of a match when a letter arrives at the destination, to bring the letters to life"

"... you're a reincarnator... you're right. When I asked Brother Irfrid the same thing, I thought for a few seconds and said, 'I don't know!' It was..."

Princess Irvara chuckled.

I'm sorry you're a young woman, but you look more like an evil grin that you're up to something than a cute smile...

"... but you only have one thing to correct... This [spell] lettering requires [spell] only the creation of ink raw materials, but once you make ink, it can be used by anyone with magical taste..."

"Shh, wow!

Of course, magic can only be used by the operator himself. It means you can't use someone else's magic. The princess's [spell] will be partially but overcoming that principle constraint.

"... I have named this new cryptographic communication a 'spell character'... that allows us to interact with state secrets and diplomatic documents without the fear of being stolen by spies..."

"Isn't that amazing!

"Ugh... right?

But unfortunately, encrypted communication by spell letters was not adopted... "

"What!? Why?

"The spell needs to be written in the life blood of the surgeon... but the nobles at the top disagreed by saying they didn't want their blood to be drained for it"

"Ugh, um..."

I don't even know what it feels like, but don't even feel that if it's for diplomatic secrecy...

Prince Ellens adds to me twisting my neck.

"The other thing is, it's a matter of appearance.

Imagine where the spell came up.

On paper, letters written in blood come up in thin blurred light.

This is a little fear. "

... Indeed.

"Confidential documents are also important diplomatic documents.

Sometimes our mindset in the other country is more important than confidentiality.

Think about it, no matter how friendly the content was in the search for peace, if it was a creepy letter written in blood, how the other country would receive it... "

If they came by and wrote "Let's get along" in the blood letters of the curse, they'd doubt the intent behind it.

"So, what's important is the contents of the sentence......?

And Princess Irvara, who says dissatisfied.

"If you fry it up, yes, but the body and decoration of the document are important in appealing to the prestige of the country. I don't understand why the civilians disagreed... but it's bad for your sister."

"... I don't know..."

Princess Irvara sneers disappointingly.

Promising research, I think.

Breaking the silence that fell into the lab, Prince Ellens said in a teasing tone.

"- Well, is it time for us to run our errands?

Speaking of which, I was. Our purpose today was to have a meeting with Prince Ellen about the Ripper investigation.

We said goodbye to Princess Irvara, and now we're going to interrupt Prince Ellens's lab.
