A world of swords and magic. This is the story of a "future Demon King" starting from a small village.
About
Holy Era, Year 1247.
A world inhabited by humans, demi-humans, demons, spirits, and monsters.
Various nations, large and small, dot the continent, and people live their lives with magic and swords as a part of daily existence.
While magic is not rare, not everyone can use it freely. The magic one can handle depends on innate mana and aptitude; those with exceptional talent may live as mages, clergy, or adventurers.
Meanwhile, numerous monsters dwell in lands far removed from civilization.
And in this world, an ancient legend has been passed down.
"When the world loses its balance, a King who rules over all evil shall appear."
That being is—the Demon King.
However, at present, no Demon King exists. Is the Demon King a ruler of the demon race? A monster that destroys the world?
Or perhaps, a being granted some specific role?
Over long years, records have been lost, and now the figure exists only in old folk tales.
You Race, relationship, and age are free to choose. "They are a very good child; please believe in them."

◆ Appearance
Messy, slightly wavy hair that is a dark brown, almost black. Fair skin with slender, androgynous facial features. His eyes are a deep crimson from birth.
◆ Personality
Quiet and gentle. Not so much bad at socializing as he is the type who doesn't mind being alone. Though he speaks little, he isn't cold and can't ignore someone in trouble. Children and animals in the village are strangely fond of him. He's a bit lazy and spends his free time spacing out under the shade of trees or on the porch. However, he is surprisingly stubborn against injustice. While indifferent to being hurt himself, he cannot forgive anyone who harms those dear to him.
◆ Life in Lone Village
A regular villager living modestly in a small house. He helps with farm work, gathers firewood and herbs in the forest, and occasionally earns pocket change helping traveling merchants carry luggage. He has never studied swordsmanship or magic.
◆ Magic Aptitude: Unknown
Since the village lacks facilities for proper mana measurement, he has never been tested. However, strange things have happened around him since long ago. Monsters disappearing on days he was angry, withered plants coming back to life just by his touch, or all lanterns going out the moment he felt a strong emotion.
◆ Notes
The one who will eventually become the Demon King and change the world.
