The three sisters were in a very good mood that day.
　Why?
　It was because everyone's vacation happened to fall on it.
　Elsa was off duty with the Order, Anna had her first day off in a while, and Meryl had decided to take a voluntary break.
　And I took a day off work too.
　An instructor of the Order, an adventurer, and a part-time teacher at a magic school.
　It was a busy day and I needed a break once in a while.
　Since all of your family members are off, we've decided to go out together. The four of us will forget about work and spend the day with our families.

"Yay!　It's a date with my dad!

　Meryl's in her pajamas and she's hugging me.

"Hey, hey. You're up really early today.
Because I'm going out with my dad today. I don't want you to fall asleep. I wanna stay with you every minute of the day.
You're such a good girl. You should get up at least once a day. Then you'd have no reason to be late.

　Anna said with a confused look on her face.

I'm a moody person. I need to be excited to be able to move. I can't do anything when I'm not here.
Meryl. You used to be able to live on that before Daddy came to King's Landing.
I used to go back to the village once a week to replenish my supply. I've been taking in a week's worth of daddy stuff there.
What is the Papa ingredient supplement ......? Elsa asked dubiously.
'Hmm. I wanted you to know that you get to play with your daddy and beg him for money. Anyway, when you make out with your dad, you can replenish your supply, right?　Dad,
That was a tough one: ......

　I looked far away as I thought of days gone by.
　In those days, I would come home once a week and Meryl would ask me for all kinds of favors.
　She wanted me to pat her head, give her a hug, kiss her cheek, bathe with her, hold her hand until she fell asleep, and let her change all her clothes when she woke up. ....... Etcetera.
　Huh?　Not much different now, is it?

"Meryl. You're never going to be able to leave your father that way. Do you want to be a broken boy who can't stand on his own?
Okay.

　Meryl said it without apology.

The word 'person' is made up of me and my dad. Me and my dad are gonna be in love with each other forever.
It's open, and it's ......

　Anna put her hand on her forehead.

'I'm glad to hear you say that, but ....... As long as me and Meryl are father and son, I'm almost certainly going to die first. I don't know if it's an illness or if I'm on a mission. So Meryl needs to be able to stand on her own, too.
I'm fine!　Even if my dad dies before I do, I'll bring him back to life!
Hey, can you bring her back?
'Yes!　Even if my dad died, he'd be able to come back and put his soul back in the body he rebuilt. Then we'd have no life span. Hmmm. Me and my dad will be together for hundreds of years.
Yes. ......

　Meryl was saying the d*mnedest things in a light tone.
　That is to say, to make you immortal.
　Since the dawn of time, the powers that be have all scrambled east and west to find immortality, but no one has ever done so.

''She's a true genius. ....... It's not impossible. She's a genius when her dad is involved. He invented a mage because he wanted to help people and earn my dad's praise.
That means ......
Dad. I'm sorry to hear that. You may have to take care of Meryl forever.
No rest for the wear, eh?
"Meryl. I support your work, Dad. Papa ...... because we all want your father to be alive.
What?
No. It's not because I don't want to leave you, Father - it's not that I don't want to leave you!　That kind of indulgence is not necessary for a Knight Commander. It's just ...... that ...... there's no point in beating your old and unskilled father with a sword.


Ha, ha. Make sure you can beat me before I get old.

　I couldn't help but chuckle .
　Elsa is still steadily getting stronger every day. One day soon she'll be a far stronger swordsman than I am.
　Well.......
　I want to stick around for a little while longer to preserve my father's dignity.

"By the way. When Meryl completes her research on immortality, will she apply it to us?
Of course you can. We're a family. Me, my dad, Elsa and Anna, we're going to live together forever and ever.
That sounds wonderful. If I can live forever without losing my young body, I'll be able to reach the heights of a swordsman.
I guess I could take all the power in the country. We could take all the power in this country and get rid of the old bastards that are roaming around now and we'd have a better country.

　Each of the girls imagined what it would be like after they became immortal.

"Well... I think we should look ahead. But it's our time off. Let's just enjoy the holiday for now.

　I said, and the girls nodded happily.
