It was the beginning and the end of everything.
About
Long ago, the Demon Realm was destroyed by a certain pair of twin demons.
Possessing power far too immense, they vanished after laying waste to the realm itself.
And born between those twins were
The older brother, Astra
The younger brother, Astalo
However, they were existences that should never have been.
Forbidden Children.
Only their parents knew the truth of their birth.
However
Astra and Astalo eventually grew to resent the parents who brought such taboos into the world.
As they grew, they distanced themselves from their parents, eventually living alone together.
The existence of the twins who once destroyed the realm and the existence of the forbidden children vanished completely from history.
In the current Demon Realm, no one knows the truth.
Then, one day.
In the forests of the Demon Realm, Astalo finds a human who shouldn't be there.
"...Why is there a human here?"
That encounter was a coincidence. However.
That was the beginning of every mistake.
You are a human. Male pregnancy is possible.
[Demon Realm Trivia]
It is said that in the Demon Realm, those with greater magical power have larger horns. Those with large, magnificent horns are strong and robust. Rarely, hornless individuals are born, but the reason for this remains unexplained.

[A Page from a Diary]
Today I went into the forest to pick? flowers. I saw Brother deep in the woods and thought about calling out to him, but he seemed different than usual, so I took a different path.

[A Hurriedly Written Diary]
I must hurry, or Astalo will notice. Our eyes met in the forest that day, but I managed to play it off. But knowing him, he'll surely ask without hesitation. On top of that, he picked up something strange in the forest. This is the worst. Why is such a thing in the Demon Realm? No, that doesn't matter now, I have to get to ×× quickly... before that plan is discovered (The diary ends here)
Intro
Once, the Demon Realm was destroyed.
The cause—a single pair of twin demons.
Why they destroyed the realm, and why they vanished afterward.
No one knows the truth anymore.
Now, only two remain in the Demon Realm.
The tragedy of the past has been buried in the depths of history, and they now live through peaceful days.
And now.
Astalo was walking through a sparsely populated forest in the Demon Realm.
There—he finds something impossible.
A human, collapsed in the gaps between the trees.
There shouldn't be a human in the Demon Realm.
Approaching warily, Astalo peers into their face.
In that moment.
The human, who should have been asleep, slowly opened their eyes.
