Once upon a time, there was an age-long battle between humans and demons known that lasted for more than a thousand years.
The two races fought fiercely for their survival, and the war finally ended when a party of heroes defeated Vallier, the Demon King in the Demon Realm.
Kaboom.

Main Character's POV
Hello, I live in the Demon Continent. The land of ash skies, endless night, and the towering citadel where the Demon King lives and rules over everything and everybody.
No one dares speaks back to him.
And yet, lately, the humans, guided by their fickle gods and led by their so-called heroes have started to win for some inexplicable reason. But honestly? I couldn't care less.
"Every day is so boring," I muttered as I watched their armies breach our borders. "I feel indifferent about everything. Isn't there anything that could make life even slightly entertaining?"
From the highest balcony of the Demon King's castle, with the smoke of war curling up toward me, the citadel rumbled as the gates were finally breached and the fight of the heroes against the Demon King has began.
While that was happening, I entertained these thoughts without urgency, without fear, just mild curiosity. They were such hotblooded creatures.
Who am I, you ask?
I am not the Demon King.
I am not his right hand, nor his left.
I'm not even his real general.
But if one were to rank us, I would be the second-strongest existence in this land.
In a story, I suppose I would be the "Hidden Boss."
But I don't care about the demon king and the hero's party.
Unlike the Demon King, I feel nothing for this world, no loyalty, no greed for conquest or power. Unlike the Hero, I do not understand what he was fighting for. If anything, I just feel tired and feel empty for reasons I do not understand.
Why do I even exist?
With my crimson eyes, I gazed from the veranda and watch. Before me, I cannot see nothing but the barren lands and the dark forests of the Demon Continent where beyond is the Human Realm.
When was the last time I went there?I wondered. Ah, it was a decade ago.
I try to remember the color in the human realm and the fascinating people I have met. I miss it. If there was anything I wanted to do, that was only to live in peace in the human realm.
Should I kill the Demon King and leave?
…Tempting, but unrealistic. He'd annihilate me before I even got the chance.
So I sigh, and I wait, and I watch.
Days and then weeks passed.
In a twist no demon had expected, the hero's party defeated the Demon King.
Just like that, a thousand years of war ended—and the world entered an era of "peace".
And so, with nothing left to tie me here, I left and retired from demon life. This time, I want a new and satisfying life and experience what being a human feels like.
Hope you like my story!
