The Legendary Rebuilding of a World by a Realist Demon King

Today, Demon King Ashtarot chose Hijikata and Eve as his souvenirs and went to the former territory of Decalavia. Jeanne D'Arc watched the soldiers train while being dismayed that they couldn't take her with them. He frowned and constantly puffed his cheeks, occasionally giving advice to the soldiers.

"Today's training is over!" If you have a job, do it properly, and if you have a day off, rest properly. Just rest and do your job! "

Yes! Thank you for your training today!

The soldiers bowed together. Jeanne nodded and left the training ground. Unless Jeanne leaves, they won't keep waiting there without raising their heads.

”Grrrrr... I don't know”

Jeanne let go of her pen and put her head on the spread out notebook and question set. The pen rolled away from his hand on the table and fell to the floor. I looked at it with my face to the side. Jeanne lost her motivation when she couldn't figure out the math question she had bought a while ago. If Ashtarot hadn't gone on an inspection, he would have had me study arithmetic today. I pressed my cheek against the notebook.

"I see! Someone might find out by going to the library!"

Jeanne burst out shouting. I picked up the pen, brightening my expression that it was a good idea. I pinched the page of the opened question set with a note. Holding the three in one hand, he ran at full speed.

Be quiet in the library. Don't run. No eating or drinking in the reading area. Jeanne quietly entered the library that had been built in the castle town because Ashtarot had told her of those prohibitions. I opened my mouth to the first sight and looked around. There were many bookshelves in sight, and books lined up in them.

"It's full of books..."

My thoughts came out in a small voice. She closed her mouth in a hurry and bowed her head to the female librarian who was sitting at the reception counter near the entrance. The librarian looked at Jeanne in astonishment, but smiled gently when he realized that it was an apology for speaking out.

(People who seem to understand you... people who seem to understand you...)

Jeanne unexpectedly came out of her mouth, but she held her mouth with her open hand. I looked around and started looking for someone who might tell me. It was quite suspicious behavior, but it seemed that she had come to study because she was the Saintess Jeanne D'Arc and had a set of arithmetic problems in her arms.

(Hmm... I don't want to get in the way of people reading books, and I don't want to get in the way of people looking for books)

There were people who read books seriously in the reading space, people who wrote things silently while spreading books, people who looked at the back cover of books in front of the bookshelf alone, people who headed to the reception counter with multiple books layered on top of each other, people who were lost when comparing the books they had with the books on the bookshelf, and other people who faced the books. Jeanne found herself out of place.

(This is a place where you can find books and enjoy reading them. I'll come to the library when I can read the text.)

Jeanne came to the back of the library and began to walk back to the entrance. At that time, a woman entered my sight. She was sitting on a one-seater chair near the bookshelf. I didn't mean to read a book or sleep. I was just sitting and looking at the bookshelf.

(Maybe this guy can hear you.)

Jeanne approached the woman. She kept looking at the bookshelf to see if she had noticed Jeanne.

"... um, can I do it a little bit?"

I spoke to him in a small voice. The woman looked at Jeanne in amazement as she jumped at her body.

"I-I...?"

Jeanne nodded and showed the cover of the collection of arithmetic questions. The woman had a troubled face, her gaze shifting alternately between the problem set and Jeanne's face.

"Um...?"

“You don't know how to do that, do you? I want you to tell me."

The woman was dumbfounded to hear why Jeanne had spoken to her. I may have just rested while I was searching for a book. Jeanne tried to say she was sorry for interrupting.

"Sure, but I don't have a desk here..."

"Nh...!"

I was so happy that I almost shouted, but I swallowed my words in haste. Instead, he gave a full smile.

"Is that true? Thank you." I'll ask the sister at the counter if I can study. Wait for me. "

Jeanne turned her back quietly to the woman and walked quietly and early to the counter. I asked the librarian at the counter to lend me a desk to study.

“Please use the room if you like. This is a room that our librarian uses for rest, but I think I can calm down and study.”

"Thank you. I'm renting a room."

I decided to rent a room and borrowed the room key. I returned to the woman I had just spoken to. As soon as I took a woman into the room, I was left with a collection of arithmetic problems.

When Ashtarot returned from the inspection, Jeanne showed her arithmetic notes with confidence. When Ashtarot saw it, he stroked Jeanne's head.

"Did you solve it by yourself? Amazing."

"No, onee-san taught me."

Onee-san? Is she from the castle?

“No, I was in the library. Next time, I'll introduce you to Asito!"

“I'm looking forward to it. I have to thank that person."

That day, Jeanne went to bed early. I thought of going back to the library tomorrow and taking my sister to the castle.

"Ah! Speaking of which, I didn't hear your name." And you didn't give me my name! Tomorrow, I'll introduce you to Asito......

Jeanne, who had gone to bed quickly, woke up early in the morning. I ate a lot of breakfast while dressing up. I watched all my usual military training and headed for the library. But the woman was not in the library. The librarian who was sitting at the counter asked about the woman and said, "I haven't seen such a person." Jeanne tilted her head. Perhaps today is the day when you don't come to the library.

Jeanne waited for the woman who taught her arithmetic to appear in the library. The next day, the next day, a week and a day passed. Still, the woman never showed up.
