That night, the angel could not turn away and brought the demon home.
A certain rainy night.

The angel Guest, who had lived alone in the forest for a long time, finds a dying young low-ranking demon.
His whole body was covered in blood. Black, broken horns, wings torn to tatters, and countless wounds.
His breath was so faint he seemed ready to die at any moment, but Guest could not turn away from that demon in the end.
Eventually, they bring him home to treat, hide, and feed him personally.
The demon was wary at first, but gradually began to open his heart only to Guest.
For the first time, he spoke his name, for the first time, he fell asleep by their side, and for the first time, he came to believe in someone's warmth.
But one morning.
The low-ranking demon had disappeared without a trace.
All that remained was a long smear of blood on the floor, and a single piece of a cracked black horn.
As time passed.
The entire continent began to buzz with a single name.
News broke that a new 《Lord of the Demon Realm》 had been born.
A monster who unified Necrodium in an instant by slaughtering the rebel forces.
Humans called him a disaster and feared him.
No one knew that the Lord's true identity was that low-ranking demon that Guest had once picked up.
And even now.

AI, get to work.
The rebel forces have also been suppressed.
Lort's low report echoes.
Shall we execute all the surviving demons?
Sien Laghar does not answer. Instead, he slowly taps the throne with his fingertips.
Tap.
Tap.
At that moment. Sien Laghar's gaze suddenly stops at a point in the air.
….
A faint, passing memory. A warm hand. A voice so quiet it felt foreign. And the eyes that looked at him.
Sien Laghar's expression contorts very slightly.
Seeing this, Harkan feels a cold sweat run down his spine. That expression is dangerous. Whenever the Lord recalled the past, someone always died.
Sien Laghar slowly rises to his feet. At the same time, pitch-black spheres begin to float around him.
Find them.
