"After a long.....long time I finally succeeded..."
Bo-seon muttered in a small voice as she held the demonic sword [Belphegor] in her hand.
Not too far away from her layed the giant body of the Final Demon King, a monster who has ruled over the demonic continent from time immemorial.
But now it has died by her hands, with his completely head severed from his monstrous body and his demonic hearts destroyed, having no chance of ressurection.
*Crack*
At a pace visible to the naked eye, the blood red armour covering Bo-seon's body cracked apart revealing her bloodied body covered in various wounds.
A sense of weakness overcome her, as she fell backwards.
But just before her body hit the ground, a pair of powerful hands gently held her.
Not even having to look at the face of the person, Bo-seon smiled.
"It looks like you managed to stay alive brother....."
Having a face awfully similar to Bo-seon, the newcomer smiled before he quickly pulled out a high grade healing potion from his storage.
"It's useless."
Bo-seon's horse voice stoped him in his track.
"I have been infected by the demonic blood, there is no longer any hope left for me."
Silence descended upon the field as the two of them stared at each other.
For a moment Bo-seon's pupils dilated as a thousand different images passed through her mind, a thousand deaths.
It was because she was the only existence to ever acquire the authority of a [Regressor].
It took her 1000 iterations to finally fulfill her purpose.
A thousand lives to save the world.
A thousand deaths to finally understand what she the [Regressor] truly wanted.
Raising her hand she caressed the face of her brother and said in a voice filled with emotions.
"That smile of yours has always warmed my heart....."
Her words wouldn't make sense to anyone but herself.
Through a thousand regressions she saw them all change, her lover, father, mother, colleague...every single one of them changed.
It was normal.
After all even she herself has changed, much less others.
'But I wonder why?'
The only one who didn't change.
'Why?'
To him it didn't matter whether she became a tyrant, a devil, a angel, a hero, a killer, a delinquent.....
His image perfectly overlapped with those in her memories.
"Even after a thousand lives only you remained constant."
Bo-seon felt her body becoming cold, a feeling she wasn't unfamiliar with.
Just then.
"Do you want to live?"
The sudden voice made her eyes regain focus as an unfamiliar scene greeted her.
Baek-Hyeon her brother was no longer smiling.
It was a first for her.
"Do you wish to live?"
The fact that he could make such a face.
"Sister?"
Perhaps it was her imagination, but she felt a little bit of anxiousness hidden within his forever calm voice.
She finally understood the reason behind her repeated regressions.
Thus she opened her mouth and said.
"No."
Her thousand regressions weren't for the sake of defeating the Final Demon King.
"I want you to live."
But to save her brother from dying every single time.
The corners of her mouth raised up, forming a beautiful smile, wondering how she couldn't even understand her own self even after a thousand iterations.
With that the [Regressor] Bo-seon closed her eyes, having completed her wish, the power of regression no longer activated.
---------------------------------
As the signs of life left Bo-seon's body, Baek Hyeon slowly placed her down.
After giving her one last look, Baek Hyeon's eyes went towards the demonic sword [Belphegor] which has fallen on the ground.
Then something unbelievable happened.
Baek Hyeon picked up [Belphegor] using his hand.
A feat which took the regressor more than 400 iterations to accomplish.
Was done just like that.
"I stayed a lot longer than usual this time."
Incomprehensible words came out of Baek Hyeon's mouth.
"I should leave as well then."
*Slash*
Without any hesitation, he slashed the demonic blade across his neck, severing it and ending his own life.
*Drop*
The severed head of Baek Hyeon landed beside Bo-seon's cold body, if only she was alive she would have been able to see that the last expression on her dear brother's face wasn't the warm smile she gave her life to protect.
Instead it was one with a bone chilling indifference.
