Well. It's nice to invite them, but I don't know where to start. Since he wants to play, I guess we should start with that. Let's start with something easy to make, as far as I know.
　The first thing I started to make was billiards. It's structurally simple and can be played indoors.
　Next was a bowling alley. It wasn't difficult to make this too, as long as you can "program" it to return a fallen pin and a thrown ball to its original position. However, after I built it, I realized that this game might be a bit too hard for the old kings to play.
　This is a fully automatic mahjong table. It's a bit of a challenge to remember the rules, but once you get used to it, you'll be able to enjoy the game's tactics as much as this one.
　I make various indoor games such as the table tennis table, the pinball table, and the air hockey.
　I also made some automatic massage chairs to relieve fatigue. I made these chairs by myself, but they are very good. It's soothing..... I'm so tired after all these years........

"Winter's night, Winter's night
Hmm?

　I was in paradise when Else, who was sitting around the mahjongg table, called out to me. She pointed at the tiles in front of her.

It's a windfall, right?
Let's see... hey...!

　Southeast, southwest, south-east, south-southwest, west-northwest, north-north, north-north, north-central.

　Dai Shiki, Ziichi Shiki, and Shichikoki Single Jockey........

Tsumo?
........Tsumo.... Triple........or is it quintuple jumbo? I'm a parent, so 8,000 all........
""Ew!"

　Lapis-san, Rosetta and Linse, who were surrounding the table, raise their voices. Terrible.......... Let's not surround the table with Else.

''Owner. Which is stronger, the flush or the straight?''
Uh, The Flash is better.

　This time, we answered questions from Sylvie, who was playing poker with Berue at another table. This time, we couldn't do it by ourselves, so we asked for help from the employees of the "Tsukuyomi" reading cafe. Sylvie, the waitress leader, Shea from the kitchen, and Belue from the receptionist's office are here from Tsukuyomi.
　Including our maids, Sylvie-san and the others were given a chance to play with us. It's best to have them do it in order to learn the rules.

''Master~, Sheska-chan, please remove me from billiards~. I can't even poke it once~
It's not a difficult game if you calculate the cushioning, the angle of incidence and the angle of reflection, and control the amount of force.

　Cecil-san sounded troubled and Sheska answered with a flat face. Ahhh, it was a mistake in choosing the right person. If it's a nine-ball rule, that's what happens if you don't make a single mistake from the break. It's called "Break Run Out".
　We left the playroom for now and headed for the kitchen of the cafeteria. In the spacious kitchen, Claire-san, Shea-san, who is the kitchen attendant of the 'moon reader', and Rene were there to help.

''Ah, sir. It's just as well, I'd like a taste.

　I took the hot baked goods Claire handed me and ate them. Yes, they're delicious.

"Don't worry, it's all in the waffle. It's delicious. Oh, it's even better if you put some whipped cream on it or something.
I see. Well, I'll try to make your own.

　With a waffle in my mouth, I took the chilled item out of the refrigerator with ice in the corner of the kitchen. 'Yeah, it's solidified properly.

'What's that, owner?'

　Shea looked at the object he had taken out with interest.

A pudding. It's a pudding, too, and it would be even better if you served it with fresh cream and fruit.

　It's called pudding a la mode. I take out a plate and turn the cup over on top of it and take out the contents. The caramel flows on top of the pudding, which is yellow and looks so delicious. I take out a spoon and take a bite. It's a little thick, but it's okay.
　Shea also takes a spoonful of pudding to her mouth. Her eyes widen in surprise at the taste, and she continues to eat her pudding, crunching away at it. Is this another success?

Fuyao-chan, I cut up the sweet potatoes as you asked, what are you going to do with them?

　The potatoes, cut into sticks in front of the rene, are in a pile on the cutting board. Rinse them briefly, drain them, and put them in a pan with a little oil, heating them over medium heat, one by one. When the potatoes start to float, you take them out, and so on. Now put them in the hot oil and fry them crispy and ready to go.
　I tried the one with a dash of salt and the other with homemade ketchup. It wasn't anything special, but maybe it's because it's been a long time since I've had them, but the fries tasted so good.

Delicious! Brother Fuyao, can I have all this stuff!
All of it? Well, that's okay. I'm just saying, you shouldn't eat too much or you'll get heartburn.

　Chuckling, he threw the last couple of fries into his mouth and handed the whole plate of fries to Rene. Claire-san and Shea-san reached out from the side and took a bite, but at the end, their hands wouldn't stop.
　For now, the food and the indoor playground equipment is just like this. The rest is security.
　When I went to the training ground inside the castle walls, three of our new knights were stretched out on the ground while breathing roughly. Yae is laughing as she looks down at them. It wasn't her who beat the three of them, but the stern, white-haired, long-bearded old man beside them and the old man with scars all over his body.
　Baba Nobuharu and Yamak Prefecture Masakage. The warlords of the Yisheng Takeda territory. They were the two martial artists of the Four Heavenly Kings of Takeda.

Yo, kid. What's up?
No, I was just wondering what's going on.

　This old man in the stable still calls me a little boy. I'm now a king, though.

Oh, Winter's Night. It's quite a sight to see. Well, they're still chicks, though.

　The old man in Yamagata Prefecture carries a large sword and smiles at me. He calls out to us.
　I had two people come all the way over to train the three of us. I thought about asking Neil from Belfast or Yae's brother, but I refrained from doing so because they seemed busy. These two, on the contrary, seemed to have some free time on their hands.
　I heard that the newly appointed head of Takeda Katsuyori had begun to act selfishly, deliberately keeping his aides away from the former head of Takeda Shingen. Even though I had warned him so much, he seems to be in some kind of trouble with Oda. Is it because he is not yet twenty years old and therefore out of control, or is he really an incompetent bonkers lord.... Takeda's downfall may be imminent.

But the boy is the king......... It's a small country, but it's nothing to sneeze at. Well, since they can use so much magic, it wouldn't be surprising if they did...
I envy these people. Compared to my masters.

　Sighing, the old man in Yamagata muttered to himself as he looked at the three men who were stretching. It looks like you're having a hard time.

How is it really? Wouldn't it be bad if we ran into Oda?
It's not so much about Oda, but rather the behavior of our lord. He would order the things he came up with without much thought, and when his domain was short of money, he would raise the taxes on his people without any hesitation. Anyway, he has a bad reputation. If this is the case, the territory could be confiscated or taken away faster than Oda can destroy it. The guy in Kosaka has been admonishing me, but he hasn't listened to me at all.

　Apparently it's going to be pretty bad. There are a number of countries where the founder of the country is a rare hero, but the second generation of the country is a fool, and that's why it has been destroyed. This doesn't bode well for Maigen-san.

"Do you want to come to our country? We're in a newly established country right now, and we need people to help us out.
Hmm. It's a tempting offer, but.... I have a duty to Oyamata-sama, too...
Baba-dono is hard. I don't mind. I agree with you since you're making the effort to invite me. But the lack of a battlefield is a bit frustrating.

　Don't be so mysterious. This is exactly why battle maniacs are such a thing. It's like having a match with His Majesty the Beast King in Mismid.

Anyway, I can't give you an answer right now. I've got to go home and talk to Naito and Kosaka first. Even if it's cancelled, I want to see Takeda's end properly.
Well, I know how you feel. I don't want to force you to do anything, and I'll do it when I'm ready.
Oh, thanks.

　The old man in the mountain prefecture put down the big sword he carried and turned his attention to the three men who were stretched out.

"Well, the break is over. The three of you, just like before, will take it.
""Yes!"

　All three of them responded cheerfully and stood up and held their weapons. You're really into it. With this, the security is also safe, isn't it? Naturally, I'm going to take every precaution on my end as well.
　Leaving the training ground, as I was about to return to the castle, the big door of the Kannon opening opened automatically. I entered the entrance hall and this time the door closes behind me. It's not an automatic door. The person who opened and closed the door is right in front of me. He is there, or rather, he is "decorated".
　A painting hangs on the landing that goes up from the entrance hall to the second floor.

'It's kind of hectic in the castle, isn't it, Master?

　A girl in a white dress came out of the painting, only the upper half of her body. It was a framed artifact recovered from the ghost fiasco of the past. When she found out that I was the owner of Babylon, she started calling me Master, just like Sheska.
　I sold the painting of the murder lord's wife long ago and used the money to frame another suitable painting. Even if I say appropriate, it's a reasonably expensive painting because it will be displayed in the castle.
　As a result, I was reborn as a girl in her late teens, wearing a white dress, with her peach-colored hair tied up with a ribbon. Her name is Ripple. It's the name of that ghost castle, Ripple Castle.

I'm busy preparing to welcome the kings. You'll take care of Ripple too?
Yes, sir. I'll let you know if there are any suspicious movements. My eyes are always on this castle. Oh, Renee-chan just broke a plate.

　You know exactly what I mean. It seems that Ripple can come and go freely in the same picture frame as himself that he duplicates in the "workshop" and can share that feeling as well. Since the duplicate does not copy your will, the main body does the supervision. We have a convenient security system.　A landscape painting was placed in the frame of the duplicate, and it was set up all over the castle. Naturally, they are not displayed in private spaces. Let's call it a ghost surveillance camera, shall we?
　For now, everything is ready. All that's left to do now is to welcome the Royal Family to the castle.
