I don't know much about it, as I hadn't heard much about it in a previous life, but the room was filled with classical-like music played from a gramophone like shape of a grimoire.

　The room is connected to a large, well-appointed courtyard, where I was practicing a dance with Nell as my partner and teacher.

"Huh, buddy, take your time.

"d*mn it, this ......!

"Look, look, it's getting hard!

　It's a good thing that Nell is now smiling and smiling happily as she takes my hand and twirls it leisurely.

　It's a good idea to be able to have a good idea of what you're looking for in a new product.

　It's not just the fact that you're not used to it, but also the fact that you've just stepped over your own feet several times and almost tangled your feet up.

　It is very difficult to move your body to the music, even with such slow movements. 　

This is for a banquet or something like that. And this one is no different. So don't look so bitter. Smile more.

Mmm. ......

　I pulled back my frown and smiled at Nell, thinking she was justified.

　It's the best-looking face of the demon king's fresh and handsome flavor. I'm sure the ladies will be very happy with it.

　Huh. ...... but I'm sorry. I can't receive that love because my mind is already trapped in certain people's minds: .......

......It's weird, so maybe I shouldn't smile.

"How dare you speak so frankly?

　Nell.

I'm sorry. I'm sorry. But just be natural and don't make any funny faces, okay?　It's the first time you've done it, and it's not something you're used to, but if you're natural and you look like you're doing it, you can usually fool yourself.

"Oh, oh, okay. I'll be careful.

　I'm not going to be the only one who has a lot of experience in this area.

　The reason why I am practicing such an outrageous dance is because of the upcoming ball as well as preparing the formal wear in town.

　I don't give a shit what the noblemen of this country think, but in human society, the reputation of a follower is directly related to his or her master. 　
　I don't want to ruin Nell's reputation by being accused of having a "barbarian who doesn't even know the etiquette of a squire" when I only know the culture of the court with my imagination and go straight to a ball.

　We don't want to give them even the slightest excuse to participate, since those who could be considered our enemies will also be there.

　Therefore, I'm trying to learn the basic manners and dances as best I can: ...... Yeah, well, it doesn't work out that well.

　I'm not sure about manners, but I've never done it before, and that's a dance I don't have even a hair's breadth of experience in, and it's too egregious.

　I'm not sure at what level I'm a bad dancer, but En, who was watching from the side, muttered, "...... ritual? That's all I can say.
　I've been practicing desperately now because I had to endure a lot.

　It's a haphazard move, but I want to be able to dance to the point where I'm not embarrassed to be seen by the type of person who says what's on my mind right out loud.

"Hey, man. Let's do that one a few more times. Repetition is the only way to make sense of these dances.

Okay, watch, Nell. I think I know something now.

　Yeah. Maybe. I don't know.

You sure?　All right, so let's do it before I forget what it feels like!

　So saying, I operate the gramophone grimoire and turn the music back to the beginning again, and then Nellie stands in front of me.

　I put one hand behind her waist and take her hand in the other and start spinning around the room again, ruminating in my brain about the teachings so far.

　Incidentally, this room is one of the rooms in the castle where you asked the king if there was a place where you could practice dancing, and he lent you the whole room because it was not in use.

　In the courtyard just off this room, Ilir and En are playing together, and Ilir is occasionally watching me and laughing at my feckless dancing.
　The usual blank expression on Eng's face, but I'm sure it's a face of concern about what's for lunch.

I'm sure you'll be able to find a way to make it work better ...... than before, no, it hasn't changed much, but it's something ...... ummmm, what is it?　I don't know, it's a bit strange. ......

"Nell, you're too fluffy to understand anything.

　Is it getting better or not?

　What is that strange feeling?

"Gwynnu ......

　I thought I was getting a little more mobile, but I don't have a lot of time ...... and I'll have to use a last resort.

...... Okay, Nell. Wait a minute.

"Huh?　Yeah, it's good, but ...... onii-san, why is it open?

"Because I was driven by necessity.

　With Nell looking dubiously at my side, I manipulate the open menu screen and exchange a certain skill scroll for a DP.

　This menu screen is now visible to all members of my family, so Nell is no exception.

　However, Leila is the only one who knows what it is, and only Leifi has partial control over it.

　Leila is fully aware of the specifications, but the others, including Reffi, only think of this transparent plate floating in the air as a magical ability of the demon king.
　Even if you look into my screen, you won't be able to read the words because they are written in Japanese. You may still be able to understand Leffi's screen because it's written in our world's language, but her screen is a simplified version, so you won't understand it.

"...... Okay, Nell. I'm ready now. We're back!

"Uh-huh, okay.

　And once again me and Nell begin to dance around the room to the music.

　But I am no longer the same person I was before.

　I step with a flourish and follow Nell's lead, moving my feet in a flowing motion.
　There is almost none of the awkwardness of my previous movements, and I'm able to move in a way that feels refined.

"That was amazing, man. It's even better than before!　What did you do!



"Hmph, if I get a little more serious, I can get away with this.

　You will be able to get a lot more information about the company and its products.

　This change in me is due to a new skill that I have just acquired by pouring magic power into the skill scroll - "Dance".

　The effect is that as the name of the skill suggests, movements related to dancing are refined.
　I've raised my skill level to 3 at once. At skill level 1, there was a chance it would be completely useless like the previous swordsmanship skill.

　Nell doesn't have any of these skills, and a normal person could do a simple dance without any skills, but ...... I didn't seem to have any talent, and I didn't have much time to practice, so this is a necessary expense.
　So this is a necessary expense, not a waste of skill points. Yes, I have saved up for this kind of situation. I'm glad I saved them for this kind of situation.

　It's a good thing that you've saved up for this kind of situation. Previously, if you were outside of the dungeon's realm, the power of the dungeon was of course out of your reach, so you were limited in your ability to use DP manipulation and skill-related things. ...... It was around the time Liu's family returned from the magical forest.
　I'm not sure if it's a good idea, but I'm sure it's a good idea for you.

　Perhaps I am becoming the equivalent of a dungeon myself. The power that originally belonged to the dungeon is now available to me as I grow.

　It's a "human-shaped" dungeon called the demon king, derived from the original forest dungeon.
　That's how close I am to the dungeon now. I'm a reformed demon king, not a reformed human.

　The demon king continues to evolve every day.
　If you lack something, just make sure you have enough.
　If you don't know how to dance, just learn the skills to learn to dance. Vive la France!

　And as I was chanting hooray for my overwhelming victory, Nell was smiling and spinning the words.

Good, now we can go to the next step.

...... yeah. Isn't that the end of it?

"No way. It's only the beginning. I was a little nervous about teaching you all, but I think I can get by on the day.

...... because, by the way, how much more do you have to remember?

Hmmm, about thirty items?　So, good luck, man!　I'll stay with you until the end.

"...... Hey!

　I just nodded to Nell, who clenched her fists adorably and said so, unable to say anything.
