Child Rearing Hero and Children of the Demon King

Now then, I have made my report to the King. Whether he believed or not aside, I have carried out my duty.
What I have to think about now is what we will do from now on.

First of all, I wrote a letter to my hometown.
The Demon King has died. From some kind of illness.
The peace has come, I think. Probably.
I have picked twin war orphans, so I am going to raise them.
I don’t have a wife. They are not my children, so please do not misunderstand.
Eh~ well, I am doing fine. Jiichan, Baachan, Tousan, Kaasan, Niisan, Sister-in-law, Brother-in-law, stay well.

I have written a letter with such contents.
With this, He got a wife!? Grandchildren, great-grandchildren!! They won’t misunderstand, probably.

Now then, where to next?
I lifted my head.
The twins on both of my sides looked up.
Writing a letter seems to be unusual for them.

「Come to think of it, can you write letters, Iric, Ilya?」
「Hmm, I have practiced, but I’m not very good at it」
「I can. But, difficult letters are still difficult」

These four-year-olds seem to be able to write a little. I’m not that proficient at writing, so I turned to Aura.
She, who was reading a book on a chair behind me is Sage’s egg. She’s supposed to be a lump of knowledge.
She should be writing down records while researching, so she should be an expert.

「Aura, won’t you become a teacher of the children?」
「Eh~」
「Eh~」

The displeased voices of the children overlapped. Aura stiffened for a moment, then let out a large sigh as if making a big resolve.

「…… I don’t mind, but please make sure to tag along, okay?」
「Eh? Me? My handwriting is terrible, you know?」
「I am aware. I didn’t mean to help me teach, but for my own safety……」
「?? I don’t quite understand, but sure」
「Let’s have fun studying, alright? Obediently, happily, gently, peacefully」
「Tsk」
「Tch」
「Yuuya-san, did you hear that!? These children just smacked their lips, did they not!?」
「Now there. I will be studying with you guys, so let’s do our best to learn, alright? How about we send a letter to my family later?」
「Nii~chan’s family? …… Yea, fine. I will do my best!」
「Onii~san’s family…… yes. I understand. I will work hard!」
「Yup, let’s work hard」

I smiled at the children who had a complete change of mind.

「Was it only me who felt a tinge of scheming just now…..?」
「Ha ha ha, there’s no way that Sage’s egg that’s treated like a parasite would be able to read Prince and Princess’ hearts」
「Same to you, Pochi. Rather, your treatment is much worse than mine, no?」
「………… That was uncalled for, woman」
