Child Rearing Hero and Children of the Demon King

The first night since Aura joined us.
A storm has come.
Before me, two women in daunting poses faced each other.

「…… What and why has this happened?」

Iric and Ilya nodded to my mutter.

「Nii~chan, you are amazing just as I thought~」
「Onii~san, please stay the way you are. At least until I grow up」
「??」

I don’t understand the meaning behind the twins’ words.
I looked in front while tilting my head to the side. Pochi was「laying down」between the two glaring women. He was done in by Sivilla’s magical power.
On the contrary, Aura wasn’t faltering. I wonder if a succubus’ magical power doesn’t work on women?

「Ufufu, who might you be, this middle-aged woman?」
「Oh my, where did you, this lass, spring from?」

Scary.

「…… Ah~ umm」

When I tried to interject between the two, Ilya pulled on my clothes.

「N? What’s wrong, Ilya?」
「Onii~san, I have suddenly gotten thirsty!」
「Ah! I feel the same!! Yeah, my throat is gradually getting drier!!」
「Eh? Ahh, then water from the canteen-」

When I picked up the canteen, it was awfully light. Haven’t I filled it just this evening and anyone has yet to drink from it?
Opening the cap, it was empty.

「Huh? Even though I have filled it full」
「How weird. But, I am thirsty! That being the case, let’s go to the river, Onii~san!」
「So strangee!! But, I want to drink!! That’s why, let’s go, Nii~chan!!」

The twins forcefully pulled on me. I’m worried about Aura and Sivilla, but I can’t ignore the children.

「Pochi~ could you stop those two? I’m taking these two to get water~」
「Are you intending to kill me, you bastard-!!」

Pochi’s shriek was drowned out by the wind. It was probably Iric.
…… When we returned, the three participants were stained with soil for some reason.

「?? What happened, everyone?」

At my words,

「No, nothing at all ohohohoho」

Sivilla laughed with a cramp,

「It’s nothing, you don’t have to mind us, Yuuya-san. As expected…… they might be children but they are of the Demon King’s blood in the end……」

Aura muttered something,

「……」

And Pochi had fainted.

「? Oh well. You should go bathe yourselves. There’s a river nearby. Ahh, Aura, how about you take Ilya and bathe together?」
「……」
「……」

Aura gazed at Ilya for a little while, and while Ilya returned her gaze, the pipsqueak let out a hmph.

「It cannot be helped. I will let you walk with me, Oneesan」
「Ufufufufu, indeed. It might be a good time to talk about girl things……」

I didn’t understand well, but a shiver ran up my spine.
…… I don’t feel any hostility coming from a monster. Why a shiver?

「Ohoho, then, I will wash you, my de-」

Sivilla who attempted to say something suddenly disappeared by riding upon the wind.

「? Did Sivilla-san try to say something just now?」
「No. Not really~」

Since Iric told me that, I guess it was just my imagination.

「Then, I will prepare the meal. Aura, I will leave Ilya in your care」
「Yeah. Shall we go then, Ilya-chan? Let’s have a looong talk, okay?」
「I would not like to catch a cold, so I shall return quickly」
「Ilya, do your best~」
「Iric too, please do your best. You do not have to show mercy if Obaasan returns」
「OK~!」

Puzzled over the twins’ exchange, I took out a pot from the baggage. The number of people on the journey increased, so preparing meals will become more troublesome. Well, the children and Aura will surely help out.
