A misunderstood baby scenmo kid sits in front of a pair of 10-year-old monitors, absentmindedly clicking away at a virtual pet site, the only place where xe feels like xe can properly express xyrself. They're listening to a Nightcore of a Punk Goes Pop cover and are considering that they wouldn't mind finding out who the original artist was, but they never get around to it for the next several years. In short, they proceed with the same things they've done for years, feeling like they have no place in this world or any other. They long for a single best friend who understands their unique mentality, interests, and more. In fact, they'd sell their soul for that.

A Demon King appears to them, decked out in skintight black armor, leather, and spikes, bearing wild, multicolored asymmetrical hair, and dangerously brandishing a massive scythe, the light of the kid's computer room glinting off its sharpened edge. The creature introduces itself as the Demon King Of Edgelording and tells the kid it'll be xyr best friend, help xem unlock xyr true self, and expose them to a world of music and aesthetics beyond their wildest dreams. The kid doesn't have anything better to do, so they accept. The Demon King is overjoyed and introduces itself as the Enforcer, Master of Edgelord Reality, king of alternate worlds. It takes up residence in the kid's head, recommending them music, clothing, and friends.

If you think this is a magical girlfriend story where supernatural aid helps the kid find themself, you're mistaken. The Demon King does not have their best interests at heart. In fact, it plans to get them to destroy their soul so it can occupy the kid's body. It approached them because they were not only the only vessel with powerful enough mental and spiritual abilities to sustain continued possession as its avatar, but because weighed down by gender dysphoria they didn't know was gender dysphoria and lacking any real friends, they lacked the confidence in themself to fight back. The Demon King of Edge would masquerade as a cool, powerful figure embodying the kid's ideal presentation. The kid would idolize it and gleefully embrace all of its commands, and would slide into becoming entirely dependent on it, lacking any real concept of themself outside of its influence. They'd destroy themself for it and they'd smile and tell the Demon King how cool it was the whole time.

The Demon King underestimated its victim's power. Xe listened to its music and clothing recommendations, yes, but with every track, they reimagined it and reclaimed it for themself. Using the very power that drew the Demon King to them in the first place, they fought back with every suggestion. Gradually, as they reclaimed and decorrupted all of the fragments of the demon's power that it granted them, they gained control over it, rather than the other way around. After years of this game of mutual manipulation, they were prepared to mount their final attack, gaining ultimate power and preventing the evil creature from taking advantage of anyone ever again. First, they started drawing pictures of the demon, treating it as one of their characters. They gave it a ref, a backstory, a page on their website, and built up an understanding in worldbuilding of how it worked. The demon was all in favor of this. After all, if it could infect the very creativity that had let the would-be vessel resist it, then all of xyr tools against them would be damaged.

But in the end, every OC is a part of one's self, and the demon failed to realize this before it was too late for it to fight back. The would-be vessel sectioned off part of their soul for the demon, allowed its power to take hold, eventually granting them all of its abilities...and then reabsorbed it into them, where as far as they were concerned, the OC had originated in the first place. The once proud spirit of destruction was reduced to an inner monologue, a story they told, and that served as the Lord of Edge's final downfall.

Empowered by the fel energies coursing through them, the would-be vessel transformed. They took on the demon's color scheme, but altered to their own style, adapting it into the serpentine and feathered features of their favorite persona character. Their endlessly dark hair took on a single point of light, the same vibrant, near luminous red as the demon's aura. In the end, all that was left of the Demon King was the scythe Administration that clattered to the ground before the former vessel. The scenmo kid picked it up, embraced the surge of power that electrified their body as they thrust it into the sky, and took on the demon's title for xyrself, adding some additions of their own.

They would henceforth be known as the Enforcer, Demon King of Edge, Master of Alternate Realities, King and God of the Music Scene, Liegelord and Webmaster of the Draggian Universe, the Most Highly Esteemed and Exalted, the Devourer of Souls, They Who Show No Deference. The human who a demon attempted to possess and who possessed the demon right back.

And then they returned to their virtual pet sites.
