Child Rearing Hero and Children of the Demon King

Aura was startled by Yuuya who opened his eyes without swallowing antidote, but the twins laughed in satisfaction.

「…… Why are you laughing? Yuuya-san nearly died!」

Ignoring Aura’s words, the twins kept laughing as they grasped Yuuya’s hands.

「Nii~chan, you met with Kaa~chan, didn’t you?」
「Onii~san. It seems that Okaa~san was pleased with you」

I blinked in puzzlement.
I thought it was just an auditory hallucination since I was in a hazy state, but it appears to have been real.

「…… Eh~ was that perhaps your Okaasan?」
「Yea! Nii~chan, you did meet her after all!」
「You went to Okaa~san’s home! It was Okaa~san!」

I looked towards Pochi while patting the heads of the delighted twins. Would this fellow know?
The twins replied with things like「Lives far away」「Separated」when I asked about their mother. I didn’t have the time to ask the dying Demon King about their mother either.

「Pochi? Do you know these children’s mother?」

Pochi who was sitting down let out Hmph and approached.

「You are not aware? And yet you call yourself Prince’s and Princess’ guardian, how pathetic」
「Sorry, I don’t know. It would really help if you could tell me」

When I lowered my head, Pochi got cocky.

「The mother of Prince and Princess is the entity that governs over death! Because she governs over death, she lives in the Netherworld!」

I blinked in shock.

「…… Netherworld?」
「That’s right!」
「…… Governs over death?」
「Indeed!」

Errr. I recalled her voice.
She spoke of scolding him, but if she’s the entity that governs over death, the soul of the deceased Demon King might have gone to the Netherworld. And why did she left the children alone after seeing the Demon King pass away?
What would she do to me were I to pass away?
…… A shiver ran up my spine.

「…… Eh~ is your Okaasan scary?」
「Dunno~」
「I do not know. But, Otou~san said that he was scared of her」

…… Demon King. Go get yourself killed once more in the Netherworld.
If you come back, I swear I will defeat you once more. For sure.

The Brave Hero who stepped with one leg into the Netherworld swore such.

Aura muttered doubtfully.

「Death? Netherworld? …… Say, just how did your Okaasan meet with your Demon King Otousan……?」

At Aura’s words, Iric declared while brimming over with confidence.

「Tou~chan said he fell in love with Kaa~chan when he died of an illness!」

Demon King, how many times did you die from illness?
