From that day onward, Ein really did reflect on his behavior! He really listened to my words—I felt like a proud big sister!

He stopped behaving in a stalker-ish way and got along well with my other friends, although I could feel that he was slightly more attached to me since he saw me as a sister figure.

After I stopped myself from trying to keep up a pretense in front of him, interacting with Ein didn't feel stressful at all. On the contrary, it was fun. Having a younger figure looking up to you feels nice, actually.

I didn't get to taste it with my past self's younger brother... Well, that was partly my fault for harboring a dislike to Domi back then, right after he was born.

Either way, things didn't seem to be as bad as I thought it would be if I were to stop putting up my defense in front of Ein.

Obviously, I tried my best to be a good big sister and corrected his wrong ways like how a real elder sister would. For example, this child's innocence clinginess that resembled a stalker's way... It got better day by day. Apparently, due to my acceptance of him, he managed to calm down as well.

Well... This incidence... I predict that it will most likely haunt Ein in the future as one of his 'dark' childhood secrets, mwahaha!

--No, I'm a good and kind elder sister, okay?

That was just a joke, teehee~.

It's not like I will definitely make fun of him in the future with this incidence... maybe.

It all depends on how he will grow up in the future~!

...Right. Because my mental is already developed, it doesn't seem like I will have a very drastic change in personality... maybe? But I wonder how about my other friends?

They will surely grow up and develop their personalities further.

It would be nice if we could stay good friends even when they have all grown up.

Yes, I will make sure that happens.

Today, Ein learned that dragons normally use treasure chests as wardrobe replacement.

"Eh?! REALLY?! I'd like to see, I'd like to see! Please, big sis Kuuuuuu?!"

Ein's eyes sparkled as he leaned forward to request Carbuncle to show him her treasure chest. I felt like Ein was so similar to a dog wagging his tail in his excitement—KUUUH, CUTE!!

"Sure, I can show you the dragons' proud treasure chests!!" Carbuncle said with her chest puffed.

"Ah... How nostalgic...," Iris clapped her hands in front of her chest.

Really, these days, I felt like I became more and more tomboy, with Iris doing feminine things... It must be due to my environment, yes!

"Nostalgic?" Ein who just went 'yay, yay~!' suddenly asked in curiosity.

"Well, we went as far as visiting the Capicastle's Treasury Room to observe treasure chests...," I recounted our experience back then.

"...Treasury... Room? Capicastle?"

"...Uh?"

I realized Ein had this 'calculating' look, and that was when I had a premonition...

"I want to go there, too! I want to visit the Treasury Room and do [Treasure Chest Observation] as well!!"

See?

"Well, that is--," I looked at Luca. Help!

"...Hey, what's with that look? Even if I live there, I still have to ask for Father and Mother's permission. We can't just go there without any notice."

"Really, big brother Luca? Can you ask the king and the queen on our behalf?"

After spending time together with us, Ein became less reserved in front of the crown prince.

"Can Harvey and I come as well...?" Iris timidly asked.

"Yeah, sure. When should we do that?" Luca suddenly asked.

"Uhm, what about during the day our parents come to Capicastle to make it easier...?" Kiri asked back.

"...Kiri, your father usually comes to Capicastle on almost a daily basis."

"...Right."

I wanted to laugh at Kiri's silly remarks when I figured what was wrong.

Then, I remembered that there was still an ongoing conflict between Naraka and Cielle—one that inevitably involved our country, Riviera.

As the Head of the Royal Knights, Kiri's stepfather got busier and had to be absent from his home or from Capicastle for quite a while.

Therefore, for a moment there (no, I'm not trying to do a tongue twister or something like that!!), Kiri forgot that his father would usually come to Capicastle on a daily basis.

I was more used to Mom and Dad's absence which increased in both frequency and length.

"Actually, Kiri's idea sounds nice. My parents often come to Capicastle—especially Mom, so it's not really a problem for me, but for Ein...," I glanced at Ein.

"Me? Oh! I remember that Mum said something about going to Capicastle... So I will ask her if I can tag along during that time!"

"Eh, really?" I was surprised to hear that Nicole would be going to Capicastle. But then again, she is now a duchess... and Four Ducal Houses of Riviera are the pillar of the country in one way or another, so I see the connection.

It's just that Dad's frequency of going to Capicastle definitely exceeds the other ducal houses—some visits are incognito if he's doing spy work. Other than that, his frequent visit is also justified because the East Riviera needs lots of work after two generation (or more?) of corrupt governance.

It's also the king's strategy to "check" on the Hartmann lineage that some people might still distrust.

"Okay then, it's a deal!"

***

That was how I got myself in yet another dejavu, but this dejavu definitely came from my past experience as Lyra, not Reinst.

Yes, I tagged along Dad and Mom as they were going to a very important meeting—I guess it would be about the current conflict again.

To my surprise, I encountered two familiar figures on my way!!

"Herbert-san, you're very early today," Dad greeted the familiar figure in front of me.

"Valkyane-san, how do you do?"

I reflexively stiffened upon meeting my past self's biological father.

What is this situation?

The one holding my hand right now is my current self's biological father, and the one in front of me right now is my past self's biological father. In a sense, my fathers are both here.

Glancing to Father's side—there's Domi.

Mom and Alt-nii were walking next to Dad and me.

"It's rare of you to bring your son along?" Dad asked in curiosity.

Thanks Dad for asking the question I've been wanting to ask!

"Yeah. I think it's important for him to be directly involved and observe the situation, since he will be the one who succeed me in the future," Father answered.

I looked at the expressionless—or the straight-faced Domi. I couldn't really tell what he was thinking about, but that straight face of his reminded me of my past self, and it made me feel a little bit uneasy at the same time.

"It should be my question instead. You seem to be bringing your children along as well? They're still so young, you couldn't be thinking of letting them observe the meeting, too, right?"

"No, of course not. You see, Crown Prince Lucius is fond of my children's company, so I brought them here to accompany him."

"Oh? That's nice for you to be forging such a close relationship so early."

"...Thank you for your compliment. However, this is nothing but a coincidence for Crown Prince Lucius to take a liking on my children."

I could sense Dad's voice went colder when he said, "take a liking". But that should be undetectable for anyone other than Dad's closest people.

I saw Mom stealthily reprimanded Dad via her glare. ...From this angle, it seemed like Domi would be able to see Mom's reprimanding glare, but he just remained as expresionless as usual. This made me feel a little bit worried.

Only Dad and Father were speaking. Mom wasn't someone who'd like to initiate conversation—and based from the look of it, Domi neither.

"Well, like father, like children, I guess?" Father chuckled.

Oh... I guess it's no longer a secret that Dad is King Titus' close aide. I looked at Dad with concern in my eyes.

I wonder if he has faced difficulties due to his close bond to King Titus?

I guess this kind of thing is a double-edged sword.

"Haha, they are my children after all."

Such was Dad's only response.

The meeting was so brief, yet it made me clear that Father hadn't really changed, even when his hair grew even grayer. And that Domi was really my (Reinst's) biological younger brother. Even his upbringing should be exactly like me (Reinst).

Unlike the other day, we were escorted to the Treasury Room.

To be more exact, Dad went first to speak with the other Royal Spies before having to attend the meeting with the king and the others as a duke.

So, Mom was the one to escort me, Alt-nii, and Clavis to the Treasury Room.

Coincidentally, the Treasury Room was close to Mom's territory—err, I mean, the Royal Magicians' work space, and Mom's Familiar—Fenix the Phoenix was guarding it.

And in front of the Treasury Room... there was yet another one of my past self's acquaintance.
