The next morning, I came to the classroom quite early, curious about the state of the training camp I had destroyed.

　To my surprise, the walls and floor of the training center had already been repaired.

　From the conversations of women who seemed to be the school's clerks who happened to be passing by, I learned that the construction work had begun at a rapid pace last night and the repairs had been completed in a matter of hours.

　Dozens of wizards who can repair buildings and dwarves who are skilled in construction had gathered and fixed the building in the blink of an eye.

　Probably, it was your father who gave the orders.
　Once again, I was reminded of the power of the nobles in this world.

　After checking the training camp, Tina walked into the central city of the school, as there was a meeting of teachers or something. That's why I had come to the classroom alone.

I'm sure you're not the only one. As expected, I was also surprised.

''Huh?''

　I was in a daze in my seat when I was suddenly surprised to hear a voice from behind me.

'You're Yohko.......how long have you been here?　I didn't notice you coming at all.

　The one who approached me was a dark-haired girl wearing a kimono. It's my classmate, Yoko.

"I've been here before you came.

...What?

　I was alone in the classroom.
　No, I had something else on my mind before that.

"Was that Yoko at the camp yesterday?

Of course.

'We're not seeing the magic of Yoko, are we?　I don't remember if Yoko was there in the first place...

　This is what I felt strange when everyone in turn used their magic and Tina said it was me and Luke the rest.

　At that time we had all completely forgotten about Yoko. And it's not just that we had forgotten.

　Even though I had been having a conversation with her just before, it's as if the existence of Yoko had slipped from my mind at that time.

'You have already seen my magic.

What do you mean?

We dilute your existence. That is my magic. That's why they didn't recognize me in the camp, just like you. Just now.

You mean by making it hard to be detected?

A higher level of magic. It has the added benefit of making you less vulnerable to physical attacks because you are less likely to exist.

Oh, there's such a thing as magic.

It's no exaggeration to say that this is my own special kind of magic. I am the only one who can use it now.

　Yoko says her specialty is magic that dilutes her existence, but I have a feeling that's not the only thing she's good at.

''Hmm, so the magic power that's stored in his or her (s)ass (s)tail is another kind of magic?''

What!

　Yohko hides the magic tail that was visible on her back.

Can you see me, my dear?

Vaguely.

Well, I didn't expect to see the tail. I'll have to turn it off.　No, this one is substandard, even my all-out self can't always win...

　Yoko mutters something boisterous.

'Hey, stop it?　We're on the same side, okay? If you don't want anyone to know, I'm not going to talk.

But I don't have a choice.

　Yoko came up to me with a look of resignation on her face.

　Then she took my right hand and kissed the back of it.

"What are you doing?
"We have a contract.

　An unfamiliar magic circle has emerged on the back of his right hand. The same magic circle also appeared on the back of Yoko's right hand.

　I've seen a similar magic circle in a book I read a long time ago. I'm sure that was a type of master-slave contract magic circle used in the eastern island countries.

　I've been thinking about this when the information about Yohko started flowing into my head.

　I've been thinking about this for some time now, and I've learned about Yohko's background through the effects of the master and servant contracts that have been made between me and Yohko.

　Yoko is a nine-tailed fox and has the ability to humanize herself. It can also grow by collecting magical power from its tail.

　A fully grown nine-tailed fox is feared in this world as a type of natural disaster. Yoko has come to this school in the form of a human in order to collect magic power efficiently.

　Once the magical power is gathered, he intends to control the teachers and students by using compulsory magic and brainwashing magic to control the school.

''........Tei!''

Pfft!　Wha, what are you doing!

　I was stunned by what Yoko was about to do and unintentionally dropped my sword on Yoko's head.

　It's a bit cute to see Yohko holding her head in pain.

'What you're going to do is my line. You were going to rule this academy, weren't you?''

This school is just the beginning. "This school is just a start." "Eventually, I plan to bring this country under my control. Now, my Lord, let's take the high road together!

I'm sorry.

Pfft!　No, don't stop!

Don't do anything dangerous for now.

'Oh, my lord, you have so much power, yet you have no interest in power? Cooperate with me, and you will have this country for yourself eventually, won't you?

No, I'm not interested in stealing a country.
What do you mean?

　Yoko looks astonished.

'If you were aware of my tail, wouldn't you have thought to use this accumulated magic to your advantage? Isn't that why you didn't tell that teacher?

No, I just thought you were hiding something, so I didn't tell you.

"Do you realize, my lord, that the nine-tailed fox is a type of natural disaster in this world? If you're aware of the existence of the nine-tailed fox, aren't you humans the ones who will immediately eliminate it or try to take it into your hands while its power is still in its infancy!

Yeah,

That's right, my Lord...

Anyway, I told you earlier that I'm not going to use Yoko's magic to do anything bad, and I'm not going to tell anyone about Yoko, right?

Oh, so that's what I signed up for.

Isn't that a waste of time?　Even if there's no contract, I wouldn't hurt Yoko. We're classmates. You can cancel the contract, okay?

I can't...

What?

I used a tailful of magic to create a bond with you in order to come under your protection, a being higher than me. The bond is too strong for me to break.

You think you can get me to disarm it?

The last thing I want is for you to break your contract and harm me, so I've made it impossible for you to do so.

Aren't you giving Yoko a free pass to sign up?

　As soon as I thought about what kind of contract it was, the details of the contract flowed into my head.

　Yohko will follow my orders, no matter what the order is, as long as it's not something that risks taking Yohko's life.

　In exchange for that, the contract can't be broken by me, and it makes her feel a little protective of Yoko. When Yoko saw me thinking about it, she seemed to realize that I knew the details of the contract.

''........Do you understand? I have given you everything but this life.

　I got a demon race (pet) that obeyed me with the power to be a natural disaster.
