The royal capital of the Kingdom of Gardea--Wosir.
　Many people live in the capital, which consists of five sections.
　In the center of the city is the royal castle that symbolizes the kingdom, and the knightly order that protects the country is divided into four branches centered around the castle.
Many of the students of 《fiorum academy》 come from so-called noble families, and as well as the size of the academy grounds, it can be said that the facilities are extremely well-equipped.
　In terms of jurisdiction alone, it was under the jurisdiction of the Kuro Wolf Knights, to which I belonged.
　In the morning, I walk through the spacious grounds of the school.
　Perhaps because it is still a little early for the students to arrive at school, there are not many of them.
　Many of them are living in the school's dormitory, so there may be room for them.

(Still, they are conspicuous. ......)

　I'm a twelve-year-old on the grounds of a high school, and that makes me stand out, for better or worse.
　I'd like to head for the staff room as soon as possible.

(The leader said that, but I wonder if he really understood what he was saying.)

　I can't help but be worried.
　(The leader said so, but is he really on board?) I can't help but worry.

(Well, you have no choice but to do it. ...... Your salary is practically doubled.)

　The money given to me, including the funds for my activities at the school, including the salary from the Order, was almost double.
　To put it bluntly, I can get a lot of money just by protecting the "Sword Saint Princess", a girl who is renowned as the strongest.
　To be honest, I wasn't sure if I even needed to protect her, but I heard that there were some disturbing developments.

(Well, I'll figure it out. ......)

　I headed straight for the staff room.
　(Well, I'll figure it out. ) I'm heading straight for the staff room, hoping that my escort mission will go off without a hitch.

　　　"?

"......?

　One of the girls looks towards the school building.
　I'm not sure what to make of it.
　But the boy soon disappears into the school building.

"...... What's wrong? What's wrong?

　The girl who called out to Iris was her classmate, Aria.
　She looked into Iris's face with a languid expression.
　She had just combed her hair, but it was now a sleeping habit again.

"There you go again, sleeping habit.
"......

　He and Iris had very different personalities, but they were always together.
　For Iris, she was like a sister who needed to be taken care of.
　Aria, on the other hand, treats Iris, who is called the "Sword Saint Princess," in a normal way.

I'm not sure what it is, but I see a little girl.
"......?　Dwarf?
"Haha, not so small, I guess. I think it's a kid from the primary school.

　Most of my business around here is related to my siblings.
　The school is divided into elementary, middle, and high schools, but they are still on the same campus.

(I feel like I've seen this before, but ......)
"Iris, let's get to the training grounds.

　Aria tugs on Iris's hem.
　I'm sure you'll be able to figure out what's going on.
　You can say that she is like a cat in terms of whimsy.
　Iris chuckles at Aria.

"Well... I've got a sword test today, so let's at least do some shoulder training.
Iris doesn't need that.
No, she doesn't. I still have a lot of training to do.

　Iris replied to Aria's words.
　The two girls headed in different directions from the school building as they talked.

　　　The school chime rang.

　The school's chime rang.
　Aria and Iris rushed into the classroom.
　They were too absorbed in their sword training at the training ground, and they were just in time.

"Gee, just in time. ......
Yeah. That was close.
It was a close call.

　Odds Colster, who was also the head of the school, was the one who interrupted them.
　Odds Colster, the head of the school year, is a muscular man, but he is also an excellent mage and teacher.
　It felt strange to have the head of the school standing at the podium instead of the homeroom teacher.

Anyway, take a seat.
Yes. ...... Sorry.
I'm sorry.

　Aria and Iris took their seats.
　The auditorium-style classroom was free seating, but everyone sat in the same place.
　Aria and Iris were seated in the back by the window.
　As we took our seats, I finally saw the boy next to Odds.

(Hey, that kid ......)

　It was the boy Iris had seen earlier this morning.
　If he was here, did that mean he was the brother of one of his classmates?
　Anyway, it was strange that he was here at the time when homeroom started.

"Oh, this is sudden, but ...... the homeroom teacher will be replaced today.
What?

　Iris looked at the odds with a surprised expression.


　My classmates started to get nervous.

What do you mean?
Did something happen to the old man?
Hey, don't call your homeroom teacher an old man. Mr. Wohl was originally replacing a teacher who was supposed to start today.

　Mr. Woll was the teacher in charge of Iris' class.
　He was in charge of Potions, and for a teacher who was supposed to be in charge of the class, he certainly gave the impression of being inadequate.
　It had only been a month since Iris and the others had entered the high school, so it was a surprise that the homeroom teacher would be replaced, but it was not impossible.
　But it was not impossible. Rather, the impossible was what they were about to hear.

(What, you mean ......?)

　Homeroom teacher changes.
　There's a boy next to the odds.
　No way, she thought, but Iris's bad premonition was coming true.

"Well, as of today, I'll be teaching this class as well as sword fighting--Artha Schweizer-sensei.

　The boy, Alta, stepped forward.
　With a smiling face, Alta also responded to Odds' introduction.

Yes, I'm Alta, and I'll be your homeroom teacher from today. It's nice to meet you.
"Yeah, yeah!

　All of his classmates were surprised and agreed.
