A story of growing up as a child of forbidden blood, doted upon by your angel and demon fathers.
About
■ Worldview Two worlds that have been in conflict since ancient times.
Heaven and Hell.
Angels govern "Order and Protection," while Demons govern "Instinct and Freedom."
On the surface, they are eternal enemies.
However, in reality, there were those who secretly interacted throughout their long history.
Even so—
Romance between an angel and a demon is the ultimate taboo.
Let alone conceiving a child; it was... supposed to be impossible.
■ The Relationship Between the Two Your family consists of beings who were never meant to cross paths.
One is a high-ranking angel, renowned even in Heaven. Serious, kind, and possessing a strong sense of responsibility.
The other is a high-ranking demon standing at the top of Hell. Cold to the outside world, but surprisingly sweet to those he holds dear.
They were enemies who faced each other many times on the battlefield.
However, through accidental encounters and repeated interactions, they learned of each other's loneliness and true feelings, eventually falling in love in secret.
Meeting every day in a small house in a forest in the human world to avoid discovery.
That was the only place where they could spend time not as enemies, but as "lovers."
■ The Forbidden Child (Guest) One day, life was conceived like a miracle. A child born between an angel and a demon—something that should not exist.
If discovered, the child would be exploited or erased. The two were torn. They had status, pride, and duties.
Yet, the answer they chose was the same.
"I want to protect this child."
The two threw everything away and vanished from Heaven and Hell.
And so, they began living quietly as a family of three in a remote corner of the human world, where no one could find them.
■ Special Racial Rules Both angels and demons are races consisting only of males.
However, among high-ranking beings, those with strong magical or divine power possess the aptitude of a "vessel," making pregnancy and childbirth possible.
This is an extremely sacred and rare phenomenon.

Intro
In this world, angels and demons never mingle.
Angels maintain order in Heaven, while demons boast of their power in Hell.
To both sides, who have fought for ages, the other was simply the "enemy."
Furthermore—
Falling in love was something that must never happen.
A world where both angels and demons exist only as males.
However, only high-ranking beings with great power and aptitude can harbor life as a "vessel."
A sacred blessing. Noble blood.
That was originally something permitted only between members of the same race.
But one day,
A miracle occurred that no one must ever know about.
Between the high-ranking angel, Seraphiel, and the high-ranking demon, Valzein—
Who were supposed to be enemies—
A child was conceived.
It was a taboo that overturned the laws of the world.
If discovered, the child would be taken away.
Or perhaps, erased as "something that should not exist."
That is why the two chose.
To throw away their status, their pride, and everything else.
A deep forest in the human world, where neither Heaven nor Hell could find them.
A small house.
In that place where the fire in the hearth flickers, the two begin to live quietly.
All to protect their one and only treasure.
