I Was Reincarnated As The Brother Of A Villainous Young Lady, But I Couldn't Use Magic, So I Used My Sword To Slash Down The Doom Flag - Chapter 25

My name is Garand Ranger. I’m just a low-ranking noble… or at least, I should be. Maybe.

Why “maybe”? Because my son—who is without a doubt my own flesh and blood—is a complete monster.

The fact that he took my silly party trick and turned it into a real sword style called “Demonic Swordsmanship” was shocking enough. But then, he went ahead and got personally chosen as the squire of a marquis’s son.

If it ended there, I’d just be celebrating like crazy. But no—he had to go and clear a dungeon at ten years old… and even defeat a demon.

I once entered a dungeon myself, thinking it would be a fun little challenge. I learned the hard way that it’s a nightmare filled with endless monsters and terrifying bosses that make you feel death the moment you see them.

They say defeating the boss closes the “gate,” but back then, I thought, Yeah, sure, like anyone could actually do that.

And demons? Even veteran knights who fight dungeon bosses every day say they never want to face one again.

But somehow, my son managed to kill one. Yeah, this doesn’t feel real at all.

Still, if it were just that, I’d only be sweating nervously about how ridiculously strong my son is.

But this situation? This is just unfair.

“Baron Garand Ranger. I’ve heard that you are Sord’s master… Have you ever considered serving the Marquis household as a knight?”

The one speaking to me with such a serious expression was Laik Hartmann, the eldest son of the Marquis Hartmann family.

Right now, we were alone in a soundproofed room, making sure no one else could hear our conversation. It felt like I was being interrogated for a crime I didn’t commit.

“I-I, um… I don’t have the strength to fight, so… I’d really appreciate it if you let this one slide…”

“…Is it because of the arrow wound in your knee? I heard from the family doctor that there were no lasting injuries after you were treated.”

“W-Well… I don’t have trouble in daily life, but when it comes to sword fighting, it’s, uh… quite difficult…”

Of course, I never actually suffered such an injury. The truth is, I’ve never been strong in the first place. Injury or not, I just can’t fight.

But if I admitted that outright, wouldn’t I be arrested for fraud or something?

Terrified of that possibility, I couldn’t bring myself to tell the whole truth.

“I see… My apologies. I understand that some wounds leave lasting effects. It was insensitive of me to bring it up.”

“N-No, it’s fine…”

What’s not fine is this entire conversation.

But if he’s willing to drop it, then that’s good eno—

“However, if being a knight is impossible, you could still serve as an instructor, couldn’t you? The way you trained Sord into such a skilled swordsman—I’d love for you to apply that expertise to my men as well.”

Nooooooo!!!

On the outside, I kept a polite smile, but inside, I was screaming and rolling on the floor in agony.

There’s no way I can instruct anyone! I have zero talent for the sword. The fact that Sord turned out so strong is the real mystery here.

If I tried training the Marquis’s knights, they’d figure me out in no time and have me executed!!

“You overestimate me. Sord became strong on his own—my instruction had little to do with it. His skills are purely the result of his own hard work and talent.”

“Ah… I see. You wish to keep your secret techniques within the family, then?”

I was just telling the truth, but somehow, Laik twisted my words into something else entirely.

No, that’s not it at all! It’s just that Sord is abnormal! Please, believe me!!

“I understand. Our family also has knowledge that we cannot share, even with friendly allies. I apologize for pushing the matter.”

“N-No need to apologize…”

It’s not a secret technique or anything, but at least he’s dropping it. That’s a relief.

Just as I let out a quiet sigh of relief, Laik brightened up and said cheerfully:

“Anyway, if I keep you here too long, Sord might get mad at me. He’s at the training grounds, right? Let’s head over.”

“Ah, yes, let’s do that.”

I suddenly remembered—Sord had just finished being scolded by his mother, Mirau, and then he immediately said he wanted more training from me.

I have nothing left to teach a guy who can kill demons, but… staying in this stifling room was worse.

So, I went with Laik to the training grounds. As expected, Sord was there, sword in hand, waiting.

“Ah, Master! Are you done talking with Laik-sama?”

Since Tilti wasn’t around, Sord casually called me “Master” like he usually did when training.

I regretted ever letting him call me that in the first place.

I could hear knights around us whispering:

“Wait, that guy is Sord’s master?”
“He doesn’t look the part at all… But I heard he’s much stronger than Sord.”
“For real? Guess you can’t judge by appearances.”

No, judge me by my appearance! I really am weak!!

“I never got the chance to tell you because of all the chaos with the attack and the squire thing, but I mastered Ice Wolf Flash! I also came up with two of my own techniques! Could you check if they’re okay?”

“Oh, sure, sure… Wait, huh?”

Ice Wolf Flash? That’s the technique that freezes whatever it cuts, right?

He mastered that? A sword technique that encases things in ice?

And two original techniques, too??

Then, right before my eyes, Sord demonstrated each one. He froze a training dummy, unleashed an explosion of flames, and then—

Sliced the sky in half.

…What?

As the knights murmured in awe, Sord looked at me expectantly.

“How was that, Master? Do they fit the Demonic Swordsmanship style?”

My jaw hung open, completely unable to process reality.

Sord… I have nothing left to teach you.

And for the love of all that is holy, please, stop drawing attention to yourself.
