'Ugh, it's cold. Has it ever been this cold?

　I've only been away for three days, but Brunhild seems to have gone completely into winter. It's hard to get up in the morning.
　The Great Sea of Trees is located south of here, so it's not so cold even in winter. I don't know if I've become accustomed to that temperature or if it's just suddenly turned cold, but it was quite cold this morning.
　This is a strange world, where there are countries with distinct seasons and countries with no seasons at all. And as far as I can see on the map, there seems to be no relationship between latitude and longitude. It seems that the east and west are also different. It's not like this world is a sphere like the earth.... There are big elephants and snakes underneath the earth.
　It's said to be related to the power of spirits, but I don't know the details. Is it related to the magic element or magic power of the natural world? There is a country with four seasons and a country with extreme cold next to it, so it is useless to think about it.
　Fortunately? Maybe it's because Brunhild has four seasons. Well, it is easier to be in the same environment as the home town. Compared to Japan, spring is a little longer and autumn is a little shorter.

I'd like to have air conditioning, though.

　To be honest, I feel like I could make it with the "program". But it's not unbearable, and we have a fireplace. "A little inconvenience is the lifeblood of life," as my dead grandpa used to say. Well, let's not. ...a hot water bottle would be nice, wouldn't it?
　The "pruning ritual" is over and Pam has given up the baby as promised. I'm sure that from now on, as the head of the Lauri tribe, or rather the "Tree King's Tribe," you'll be able to exercise your skills in the Great Sea of Trees.
　I've heard that Brunhild is recognized as a friendly nation that saved the tribes of the Great Tree Sea, and they are always ready to help you if you need anything. I'll feel free to lend a hand then.
　I don't know anything about what happened to the Rivets who plotted to take control of the Great Sea of Trees. Pam only told me that they were judged by the Great Sea of Trees, and I had a feeling that it would be better not to ask, so I didn't want to pry any further into the matter.　　
　I walked out to the balcony in the cold and saw that someone was already working on the training ground that I could see in the distance from here. It's hard to see much in the morning haze.
　I stretched my vision with my 'long sense' and saw that Morobane's sister was playing against me. My opponent.........Lou.

''This early in the morning........''

　I guess that was it after all. Maybe it was frustrating to lose to Rengetsu-san. He looked like it was nothing, but he's a pushover and he hates to lose, my fiancés.
　Well, when I came back with my Morobane sister, everyone in the castle was surprised to see me. Well, I had never said a word about having another sister, so it was no surprise.
　I asked Kosaka-san, "How many more brothers and sisters (siblings) do you have? When I answered, "Well........" with a certain honesty, I don't know what I misunderstood, but he looked at me warmly and said, "It's the bloodline....... It seems they labeled me something like "The Mochizuki family is womanizing. I'm not a half-sister and brother! Before that, though, they really aren't even sister and brother.
　Naturally, what surprised me more than that was Morohane's battle prowess. In order to show off her abilities, she held a random fight with the knights, but her sister easily won the match 1 to 80. Not a single one of them even grazed.
　Moreover, she was able to point out exactly what was wrong with the eighty men and where they needed to improve. How high-specified are you, Sword God?

''As expected of His Majesty's big sister.......''

　Whenever she had time like that, Morobane sister would put training on against the Knights of the Order and do it. It looks like she's going to make a hell of a level up in a few months. Well, it's not a bad thing, and I'm grateful for that.

''Good morning!''
'Good morning, Mr. Wintery Night.

　After getting dressed in a hurry, I arrived at the dining room to find Yumina, Linse, Else, Yae and Hilda, and my sister Hanakoi taking their seats. While I was in a daze, Rene, the maid, brought me a cup of herbal tea to wake me up.
　I was thanking her and patting Rene's head, when the door opened and Lou and Morobane sister came in.
　We have a breakfast at seven o'clock, but we don't have to eat it all together. If we have time, we try to have it together, though. So everyone starts eating after seven o'clock, but today it looks like we're all together. It's rare that Hanakoi's sister is at breakfast. She's always in bed.
　Occasionally, Sue joins this face, but she doesn't seem to be here today.
　Sue's room in Duke Ortlinde's mansion and the room in this castle called the Transitional Room are connected to the room called the "Gate" enchanted glimpse. Of course, no one but Sue can pass through it, and when she passed through it is recorded.
　We're engaged, and I've given her permission to come to the castle any time she wants to, but I've told her to get her meals over there as much as possible.
　I think it's better for parents and children to have a meal together after all. The duke will be lonely too.
　When breakfast is over, each of us begins our own work and training. Yae, Hilda, and Morobane sister join the knights in training and inspecting the country, Yumina and Lou consult with Naito's old man about the status of the city's development, Else and Linse train and cultivate the crops they have developed, and Hanakoi sister works in the counseling room for love troubles.
　It's not something the king's fiancée would do, even if she were to do it, but everyone does it because they love it.
　As for me, in the morning, if there is someone who comes for an audience, I'll see them, and if not, I'm free. Mr. Kosaka would briefly ask me about domestic problems, and then I would divide the problems into those that would be dealt with immediately, those that would be dealt with after thinking about it for a while, and those that did not need to be dealt with.
　Mr. Kosaka would try to use the power of the people as much as possible to deal with matters that would be easily handled if I were to travel to Japan to deal with them. If I were to do everything, the country would be dependent on me. When something happens to me, if the country can't handle it on its own, it's meaningless.
　So, I am treated as a hindrance to the country. Well, it's easier to do that.

I wonder how cold it is in winter here.
'Yes. I don't think it will be that cold this year, though. This year we have a 'hot carpet' made by His Majesty, so that's a big help.

　Lime, the butler who brought us tea after dinner, told me so. There are many large rooms in the castle and it's hard to warm up. That's why we put down carpets with the fire-attribute Warming enchanted in the audience rooms and the chambers.
　I also gave Lime a special Warming enchanted suit as a gift. It's an excellent temperature-controlled suit. Lime is one of the earliest people to get up and move in the coldest hours. It didn't seem like he would accept it if I gave it to him normally, so since it was just about Lime's birthday, I used that as an excuse to force him to give it to me.
　I didn't want my perfect butler to catch a cold, you know.



　Well, I don't have an audience scheduled for today, so I'm free. No, I'm not really free. So I started to finish the piano that I started after I came back from the sea of trees.
　The structure itself is not difficult, but I made a piano, which is just a pretend piano, and I programmed the parts whose structure I don't understand. I don't have an absolute sense of pitch, so I had to add scales by relying on the sounds I could hear from the piano app on my phone.　
　It had 88 keys, so it could have been a 65-key studio upright.
　I was a little nervous, but I finished tuning all the keys. Anyway, I sat down in the chair and pressed the keys. I played Do Re Mi Fa Solacido and then Do Silla Sofa Miredo and back.
　It's been years since I've played it. I remember when I was a kid, I couldn't switch the fa to my thumb, so I practiced. So when I went back, I couldn't switch the middle finger to the middle finger this time. My fingers were shorter than they are now.
　I got nostalgic and repeated over and over again, dolemifasolacido, dozira sofa mired, dozira sofa mired, dozira sofa mired....
　And then he started to play the famous song "Cat Stepped on it", which everyone tries to play. I was on a roll and played various arranged versions of the song. I also played a jazz version.
　When I finished playing, I heard the applause from somewhere. When I turned around, I saw a cherry tree with a red ball applauding.

'Is that a musical instrument?'
Yeah, yeah. It's called a "piano. A keyboard ... well, I guess it's a category between a percussion instrument and a string instrument.
I want more. Play something else.

　That's what I'm saying. Hmmm, well, it's easy enough then. I don't know if I can play it since it's been so long, but it's perfect for this season.
　I start playing it in a light tempo. That's a classic for the Christmas season. I'm not sure if it's December here now.
"Jingle Bells".
　I didn't think that this song written by an American pastor more than 150 years ago would be played in another world.
　Sakura was shaking her head slightly from side to side in time with the rhythm. It seems that she was pleased with it. It seems that even Benetama is listening to me with his eyes closed. I was so happy that I couldn't help but hum a song.
　When she finished singing, she clapped for me again. I'm so embarrassed.

Tell me that song. I want to sing cherry blossom too.

　Sakura asked me that with a glint in her eye. It's unusual for her to say that. She doesn't usually show much emotion, though.
　In response to the request, I play a little slower this time and sing the lyrics firmly from the beginning. Sakura hums them to herself as she follows them. I finished the song once and was about to ask her if she wanted to sing it again, but she replied, "I've already learned it. ...That was fast.
　With that, I began to play lightly again at the original tempo, and Sakura began to sing along with it. Hey, what's that?
　He's meh. Her clear, crystal-clear voice echoed around the room. I didn't know she could sing this well. When she finished singing, Sakura smiled with satisfaction.

It's amazing. Maybe Sakura was a good singer?
'I don't know, but I think I might like to sing. Tell me more?

　He played the songs he remembered in the hope that it would help his memory return. She avoided the classical songs without lyrics and sang pops, songs, enka, children's songs, and Japanese and western music alike.
　To my surprise, Sakura was able to remember the lyrics to all of them correctly after just one listen. It seems that her memory is really good. It's ironic that a girl with amnesia has a great memory.
　But this singing talent would be an important weapon in her life. Do you want to produce her as an idol? No, she doesn't want to do anything too obvious, given her personality.
　In the first place, this piano wasn't made for accompaniment. Well, even if you teach Yumina and others the piano with this, it is doubtful that they will be able to freely manipulate the Fragarach Sword.
　Before I knew it, everyone in the castle had heard the beautiful voice of the cherry blossoms and my accompaniment, and before I knew it, everyone in the castle had gathered to listen to her singing.
　When she finished her performance, a shower of applause poured down on us. Sakura was looking down, somewhat embarrassed, but when her good friend Linse praised her for her performance, she had a smile on her face, which wasn't too bad.
　Then Sakura's mini-recital continued for a while. Even though she was somewhat shy, she seemed to be less so in front of her acquaintances, and she sang with pleasure.
　I continued to play along, thinking that next time I should play her a song from my phone that she might like.
