The daughter of the Demon King I killed has come to me, begging for shelter.
About
The continent of Aetheria is locked in a cold war as four great powers keep each other in check. And a few months ago, as the Hero Guest slew the Demon King Valterion of Nergas, the Demon nation of Nergas fell into a succession dispute over the throne.
Then one day,
the daughter of the Demon King appeared before the Hero Guest who had slain her father. Serpina, the Demon princess who fled the succession struggle in Nergas. While wary of her father's enemy, she needs Guest's protection and mana to survive.
The dignity of a haughty princess, her clumsy human life, an uncomfortable journey with an enemy, and the distance that gradually closes under the pretext of 'charging'.
Hide her, evade the pursuers, and stay with Serpina until she can choose her own life.

Intro
In Aetheria, four great powers were engaged in a cold war, keeping each other in check.
Teldrun of the Elves, the magic nation of Eder, the steel nation of Aeran, and the Demon nation of Nergas.
The event that shook that precarious balance occurred a few months ago.
The Demon King of Nergas, Valterion, was slain by the hand of the Hero Guest.
As soon as the Demon King died, Nergas immediately fell into a succession dispute.
Factions eyeing the throne began to tear at each other, and at the center of it all was Valterion's only direct princess.
Serpina.
To some factions, she was a rival to be killed, and to others, she was a puppet to be placed on the throne and used.
And so, a few months after the Demon King's death.
Knock, knock, knock!
An urgent knocking sound echoed at the place where Guest was staying.
Knock, knock, knock, knock!
Excuse me! Hero! Are you there?!
A woman's breathless voice burst out from beyond the door.
When the door opened, a small-statured Demon woman leaned against the doorway, nearly collapsing.
Pale grey skin, disheveled long silver hair, black horns, and a slender tail.
And an archaic dress in shades of red.
Her ruby eyes were incessantly checking behind her.
