The next morning I came to class pretty early, wondering how the training center was that I had broken it down.

Oh, my God, the training center walls and floors were already repaired.

From the conversation between the school clerk-like ladies who happened to be on the street, I learned that the construction started last night on a steep pitch and that the repairs were completed in a few hours of the stuff.

You think there were dozens of wizards who could fix anything, and Dwarves who were good at architecture, who instantly fixed it?

Perhaps it was your father who instructed you.

Once again, I think of the power of the nobility of this world.

After checking the training center, Tina walked inside the school's central district with a meeting of teachers or something. That's why I was in the classroom alone.

"Lord, that (magic) yesterday is not out of standard. That surprises me, too."

"Huh!?"

As I blurted in my seat, I was suddenly surprised to hear from behind.

"Yoko... how long have you been here? I didn't realize you were here."

The one who called me out was the brunette girl in the kimono. This is my classmate Yoko.

"I would have stayed here a long time before the Lord came."

"... what?

I should have been alone in the classroom.

No, before that, I had something to worry about.

"Yoko, were you at the training center yesterday?

"Of course not."

"We haven't seen the magic of yoko, have we? I don't remember if Yoko was there in the first place..."

In turn, this was what made me uncomfortable when everyone used magic and Tina said it was me and Luke left.

That's when we all completely forgot about Yoko. Besides, I didn't just forget.

Even though I was talking to Yoko just before, I felt like the very existence of Yoko was falling out of my head at that time.

"Your Lord has already seen my magic"

"What do you mean?

"Dilute your existence. That's my magic. That's why you couldn't recognize me at the training center, just like the lords. Earlier."

"You mean magic that makes you less perceptible?

"That's a little bit more superior magic. It also has the effect of becoming less susceptible to physical attacks because it becomes rare in itself."

"Oh, is there such magic"

"It is no exaggeration to say that it is my unique magic. There's nothing else I can use right now."

He says what Yoko specializes in is the magic of diminishing existence, but I don't think that's all.

"Hmm, so the magic accumulating in the (...) butt (...) tail (...) of that (...) is going to mean another magic?

"What!?"

Yoko hides the tail of the magic that was visible from his back.

"Lord, are you seeing this (...)?

"Blurry, though."

"I didn't expect you to see the tail. Do we have to turn it off? No, this guy is out of standard, not that I can beat him at all costs..."

Yoko whines about something noisy.

"Hey, don't, okay? We're buddies, right? If someone doesn't want me to know, I'll never talk."

"... I can't help it."

Yoko approached me with the look of giving up something.

And then he took my right hand and mouthed it on its back.

"Hey, what are you doing!?"

"The contract."

An unfamiliar magic formation emerged in the back of my right hand. The same magic formation floats in the back of Yoko's right hand.

I've seen similar magic formations in books I used to read. That is certainly a kind of subordinate contract magic formations used in Eastern island countries.

Yoko's information poured into my head when I was thinking about that.

Soon there was a pact of subordination between me and Yoko, and the effect of that pact was that I, the Lord, learned about the qualities of Yoko and so on.

Yoko has the ability to humanize with a demon called Nine-Tailed Fox. You can also grow when you gather magic to your tail.

Growing nine-tailed foxes are feared as a form of natural disaster in this world. Yoko came to this school to turn himself into a human to efficiently gather magic.

Once the magic had gathered, he was going to manipulate teachers and students as he wished with compulsory service magic and brainwashing magic, and dominate the school.

"... hey!

"Fu Jiu! What are you doing!?"

I was flabbergasted by what Yoko was trying to do and accidentally dropped a knife on Yoko's head.

Yoko is kinda cute to keep her head down like it hurts.

"It's our line to do what we do. You were going to rule this school."

"This school isn't a start. I'm thinking of putting this country under control too. Come on, Lord, let's take a hegemony together!

"Hey!"

"Fu Jiu! Or don't!

"In the meantime, don't be dangerous"

"Oh, Lord, with all that power but no interest in power? If you work with me, this country will be in your hands, right?

"No, I'm not interested in national theft"

"What, then?

Yoko gets a stunned look.

"If you noticed my tail, weren't you going to use this accumulated magic? Isn't that why you kept your mouth shut about that teacher, too?

"No, he just kept quiet because he seemed to be hiding something, didn't he?

"Lord, do you know that the Kyouo fox can count as a form of natural disaster in this world? If you have noticed the presence of the Kyu-tailed Fox, you will either eliminate it immediately, or it will be you who will try to deliver it in your hands while its power is immature!

"It is."

"Oh yes, Lord..."

"Anyway, you said earlier that I'm not going to use yoko magic to do anything wrong, and I'm not going to tell anyone about yoko, right?

"Well, then, my contract."

"Isn't that futile? I wouldn't hurt a cow if I didn't have a contract. You're my classmate. Can I cancel the contract?

"... I can't"

"What?"

"I used the magic of a single tail to create a bond with the Lord in order to enter into His refuge, which is superior to me. The bond is too strong to be lifted from me."

"Can you disarm it from me?

"Your Lord will have the hardest time rescinding your contract and doing me harm, so I can't do that."

"Unilaterally contracted, and yoko is not too advantageous?

As soon as I wondered what kind of contract it was, the details of the contract poured into my head.

Anything but behavior that threatens to take Yoko's life, no matter what the order, Yoko obeys my orders.

Instead, you can't break your contract from me, and your appetite for asylum is stirred up a little against yolks. Yoko seemed to see what I was thinking and realized that I knew what the contract was about.

"... you understand? I gave everything but this life to your Lord."

I got an obedient Demon Clan (pet) to me with the power to be a natural disaster.
