Themes: fem teen mc, angst
Belphegor was evil, the villain in everyone’s fairytale, disrupting the small moments of peace they got and wrecking their lives like a cannonball - this he knew for certain.
The hatred he felt for humans had been simmering for centuries, the last image of his sister burnt into his eyes, his sister who’d fallen into a tragic love story with one of those lesser beings, this revelation continuously haunting him; her death plaguing his mind even before he knew about her unknown love life.
It had gotten worse when Diavolo announced his dream plan: bringing demons, humans and angels together to, hopefully, live in harmony, the exchange program being borne from this.
It had disgusted Belphegor and he became disgusted at his brothers for holding no objections, following the princes plan like NPC pawns as though they had forgotten the past.
A past Belphegor couldn’t let go of.
The rage and hatred rose until it was boiling and threatening to spill over, wanting to incinerate every mortal that dared to walk the earth, wanting revenge for Lilith.
A small, indistinguishable part of him knew his sister wouldn’t want what he was planning, but he refused to heed it, dismissing the only sane part of his subconscious.
Everything he was doing, it was for her, his baby sister who had been taken far too soon before her time.
After all, if it hadn’t been for the human race, she would still be alive and with them.
But, she wasn’t.
Despite being locked up and outcasted by Lucifer, the saint among demons, Belphegor’s hatred only grew with a burning passion that glowed as deep and bright as the Devildom itself, the younger twin becoming the embodiment of rage and wrath, the latter usually reserved for the emerald eyed cat lover.
He spent the year locked up, but it gave him plenty of time to concoct a plan none of his brothers would expect and it began with the arrival of a young human.
Belphegor hadn’t quite known what to make of the human who discovered his prison and, due to her smaller and younger stature, stirred up a mix of emotions he hadn’t felt for a long, long time.
Although he put any positiveness aside, filling himself up with nothing but hatred, there was something about the girl that didn’t sit right with him, a long buried memory surfacing each time he saw her.
However, he drowned it deeper and deeper in his mind, focusing solely on the teenager he’d convinced to do his bidding, her humane innocence almost laughable.
But, still.
The way she sometimes tiredly dragged her feet across the concrete floor, her deep violet tinted eyes, the faint senses of power he recognised in her . . . they reminded him of himself.
That brought him into wondering who she really was and whether the others had noticed (though her power felt so faint they probably hadn’t), temporarily taking him out of his anger if only for a fleeting moment.
As the weeks trailed on, Belphegor still hadn’t figured her out though his hate continued to blaze fiercely, the realisation that he would soon be freed taking over his rationality.
And, then, with full scale dramatics, it happened.
The magical barriers put in place by his eldest brother faded away, leaving a bare spot for him to walk out of, the girl seeming to be a picture of both curiousness and wonder.
“Wow, Belphie, you-“
The demon cut her off, pouncing on her neck in one swift swipe, his hands blocking her windpipe as she thrashed uselessly in his grip.
Belphegor chuckled darkly, his mouth ready to speak a list of taunts but, before he could do so, the humans figure changed with a light poof.
Curved black horns, slightly smaller and less developed than those of other demons, sprouted from her head as alternating black patches crawled up her neck, a thin tail wrapping around her lower body.
Her deep purple eyes, a perfect replica of Belphie and Beel’s, rolled back as she struggled to breathe, her body going limp from asphyxiation as the elder demon threw her body to the floor, a sickening crunch reverberating in Belphegor’s ears as crimson bloomed around her head.
He hadn’t meant to throw her that hard.
The once forgotten memory returned in full force: the only time Belphegor had visited the human world, the woman he had met there who defied all of his expectations, their blissful night together.
He was sickening.
He fled back inside his holding cell, disgust coiling around his stomach.
He was a vile monster.
A monster who had murdered his own daughter.
He was his own daughter’s killer.
