Chapter 9 – The Former Demon King, Strengthening Himself


Chapter 9 – The Former Demon King, Strengthening Himself

—That day, in a corner of the mansion—

”Are you still concerned about Yuuki-dono?”

“….yes. Sensei”

”Again, it’s unlikely that Yuuki-dono has used the ‘Ancient Magic’. It’s because that is a magic that can only be used by the Chosen One”

”Y, yes. I’m well aware of that but”

”I understand that Xellos-sama is wary of Yuuki-dono. Did you see how Baron-sama behaved earlier? He cared for Yuuki-sama so much. As expected, it seems that he is being ensnared. This proves that Yuuki-dono wants to overthrow you and take over as the legitimate son”

“….sensei, I’m…”

“Don’t ever let your guard down. Xellos-sama”

Tutor Kachel grabbed Xellos Grossalia’s shoulder.

“Yuuki-dono is steadily implementing a plan to get the servants on his side. The other day, he was trying to treat his servants to the prey of the hunt. This is an obvious attempt to curry favor with the servants. I wonder what would have happened if I hadn’t stopped him”

”Is Yuuki really…trying to get rid of me?”

“It’s something common in a noble family”

Kachel muttered bloodily.

“Things like an illegitimate child joining a noble family and eventually taking over the house. To neglect someone who is the legitimate son just because he is a little better is unforgivable. You must show to them. Show to them that your true power is not just like this. And”


”Listen, Xellos-sama. The only one who is on your side is this Kachel Mieghem. Do you hear me, I’m the only one on your side”

Kachel repeated the same words.

The illegitimate child has invaded the Baron family.

The Baron even accepted Yuuki, everything was just a scheme.

“I have faith in you. Xellos-sama”


“Xellos-sama is the one whom Kachel Mieghem should serve. If this body do not possess a great amount of magic power, then I might not be able to gain the trust of Xellos-sama and—”

“N, no. I also have faith in Kachel-sensei”

“Then please repeat the same words as me. Grasp this amulet tightly—Yuuki Grossalia is the enemy—and we have a common enemy. Moreover, we must fight against him, and”

“W—we have— a common enemy”

”No matter what Yuuki-dono do, he can’t win against me and Xellos-sama. I’ve already taken steps to make sure that my magic and Xellos-sama’s magic are united. So please be at ease on the day you’re taking the examination. Xellos-sama”

—At the same time, in Yuuki’s room—

After returning to my own room in the detached building.

I decided to investigate the phenomenon.

Xellos nii-sama’s ‘Ancient Magic’ was activated by drawing a crest in the air and chanting a spell.

The crest could be read from the movement of his fingers.

But for the spell, I didn’t understand what it was. As far as I know, that’s not the language of any country that I know of.

It’s probably words that are used exclusively for the ‘Ancient Magic’.

And the only way to know that is to learn from tutor Kachel or the ‘Magic Guild’.

Even though I only drew the crest and didn’t chant the spell.

But the ‘Body Strengthening’ was activated.

Let’s think again from the beginning.

There are two types of magic in this world, the common magic used by the general public and the ‘Ancient Magic’ discovered by the ‘Sanctuary Church’.

The differences are power, duration, and magic consumption.

Compared to the common magic, the ‘Ancient Magic’ has 3 things that put it in a different league than the common magic.

Nii-sama with his ‘Body Strengthening’ fought evenly with otou-sama who was a veteran warrior.

After that, I drew the same crest that nii-sama had shown me then my body became stronger too.

But the problem was, why did my magic got activated.

“Let’s experiment with it”

I took out a piece of parchment.

With a pen and the ink, I tried to draw the crest from that time.

“…………Nothing is happening”

Next, let’s use my ‘Magical Blood’.

At that time, things started to change when I drew the crest on the palm of my hand with the blood on my fingers.

So let’s do the same thing now.

I cut my fingertips with a knife and draw on the palm of my hand with my blood on the pen….

It was activated.

My body feels light and when I stretch it……I feel unpleasantly fast.

Let’s not do a jump as I might crash into the ceiling.

After that, I just silently count the number of seconds. 100…… 200…… about 600 seconds. So, 10 minutes huh.

Next, I’ll put my blood into the pen and draw the crest on a parchment this time.

And when I tossed the parchment—it just fell normally.

So, there is no way to use the ‘Body Strengthening’ on a parchment huh.

“……that means my ‘Magical Blood’ is the cause of it?”

I displayed the status again.

‘Yuuki Nosferatu’

Age: 13

Race: Unknown

Stamina: B

Strength: B

Agility: A

Magic: S

Dexterity: B

Skill: Flight. Magical Blood. Stealth. Ice Magic. Servant Creation. Erosion. Purification. Ancient Magic Aptitude.

The skills increased.

What’s the meaning of this? Until now, there was no such ‘Ancient Magic Aptitude’ skill.

In the first place, I never use the ‘Ancient Magic’ in my past life too.

However, I was stabbed with the ‘Ancient Artifacts’ Holy Sword at the end….

“Was it from that time!?”

When I died in my past life, the Holy Sword was stained bright red with my blood.

And my blood is like a part of my limbs.

So when I died, I was connected to the ‘Ancient Artifacts’ Holy Sword.

In other words, I reincarnated in the state of being connected to the ‘Ancient Artifacts’.

It seems that it had some kind of effect on my soul, and as a result, I’ve gained an aptitude for the ancient magic.

So, the ‘Ancient Magic’ could be activated just by using the ‘Magical Blood’ to draw the crest?


When I reincarnated, I thought that the humans of this era might have analyzed the ‘Ancient Artifacts’ and developed their culture with it.

However, that didn’t happen.

Because of the war, the ‘Ancient Artifacts’ had disappeared, and the ‘Ancient Magic’ belonged to the ‘Rindobell Magic Guild’.

But what if I become an expect in the ‘Ancient Magic’….

“Maybe I can develop the culture and make this world a more comfortable place”

Okay. End of delusion.

It’s impossible. Impossible.

I’m the one who was called as the Local Demon King in my past life, and now I’m the illegitimate child of a Baron family. Let’s not get my hopes high.

My desire is to study the humans and be able to pretend like a human. That’s all.

Let’s leave the affairs of the human world to the humans.

“I hope Xellos nii-sama joins the ‘Magic Guild’ and get better”

I laid down on the bed.

From outside, I could hear my little sister, Lumia and Martha’s voice.

”Yuuki nii-sama caught a rabbit! So the lunch menu is nii-sama’s meat!”

“Yuuki-sama is amazing. I’m sure it will be delicious”

Lumia, that sounds like you’re going to eat my flesh.

Martha should lower down her voice a little too.

Everyone in the mansion knows that the two of them are childhood friends, but it would be troublesome if Kachel heard about it.

“……I’m fine with this”

Reincarnated as a human and has a normal family too.

From now on I can go to the school and gain knowledge of this era.

I have been treated well enough as an illegitimate child of a noble.

I’m no longer the ‘Local Demon King’ and I’m no longer the ‘Vampire King’ too.

What happened in the past life is over now.

The ‘Sanctuary Church’ that cornered me is gone too.

‘Immortal mage! You, as the Demon King, are plotting to conquer the human race, aren’t you!?’

As a Demon King, I don’t think there will be such an accusation anymore.

Nobody was trying to conquer the human race.

All I wanted to do was improve my magic, make it easier for the people in the village to draw water…… and reduce the rate of livestock contracting disease so that they could have meat on a weekly basis—

“…………it’s depressing. Past life”

I decided to sleep in until lunch, so I closed my eyes.

That night, the butler Neil told me about the coming day of Her Royal Highness the Princess.

From tomorrow afternoon, one of the chosen sites for the exam venue at the mountain behind the mansion will be off-limits.

I decided to sneak out of the house again.
