Finding out they were soulmates shouldn’t have changed the very nature of the war their people waged against each other. It shouldn’t.
Dabi disagreed.

Summary
He shrugged off his coat, pushing the thought away and turning to hang up the coat by the door. Behind him, Dabi’s breath hitched, and he felt the corner of his lips tug up.
Gotcha.
Or:
Keigo's having a rough night. He knows exactly how to fix that.

Summary
Hawks died. He died in flames and chaos, panic around him. He died with ash in his lungs and blood on his lips, and loss dragging his soul down. He died with screams echoing in his brain, hands too-far away reaching for him, and no wings at his back to catch him as he fell. He died with Dabi shouting his name, clear across the battlefield, that familiar voice curling in his ear.
And then, against all expectations, he woke up.

Summary
Hawks died. Then, he woke up.
He really wasn't expecting that second part, to be honest. But like hell was he going to let go of a chance to change the world for the better. And if he can dismantle the HPSC, root out All for One's corruption, maybe he could save himself and his family in the process.
But oh man, what a change that brings about.

Summary
In a world where Names have power, and wild things run on the edge of a world where there's so much more to see. If only you learn how to look for it.
The thing about learning to look, is that other things learn to look back
Or, in other words, welcome to another pit of fun where anyone named Takami is also Todoroki bait. Come right in.

Summary
“I can explain,” she rushes out, even though she has actually no idea how to explain.
“Yeah, can you explain why I found this out from a Twitter thread instead of from you?” Bobby says. He grabs his phone and pulls up a web page, then slides the phone over to Rumi.
She freezes.
It’s not some tell-all about her secret demon identity.
She looks down at the photo, taken by some resourceful paparazzo, of Jinu waving goodbye as he slips out the back of her condo building. In the background, blurry but still obviously her, is Rumi.
//
Five times people assumed Rumi and Jinu are together (and one other time entirely)

Summary
After the fall of Gwi-Ma, the feared Demon King, the girl group Huntr/x claimed victory… but the war was far from over. The mystical barrier, Honmoon, was merely contained—a golden crack between worlds.
Now, ancient secrets are surfacing: Gwi-Ma was only one of the Seven Kings of the Underworld, primordial entities born from the vices and pains of the human soul.
With the balance broken, portals begin to open. Rogue demons cross into the human world—some hungry for power, others seeking redemption, freedom… or love.
At the heart of the chaos stands Rumi, carrying a power she doesn’t understand and a past that was kept from her. Her father—one of the most dangerous and enigmatic exiled demons—has returned, challenging everything she thought she knew.
And Jinu, torn between guilt and desire, may hold the key to saving or damning both worlds.

Summary
Her fingers brushed a neglected box tucked beneath the lowest shelf. She knelt, lifting its surprising weight. Inside lay stacks of tapes, CDs, albums, and letters — but her gaze snagged first on a loose photo resting atop them:
Ryu Mi-yeong at Han River Park, pregnant beneath a charming sunhat. But what stole Rumi’s breath wasn’t just her mother—it was the man beside her. Tall, powerfully built yet relaxed, his careful arm circling Mi-yeong’s waist. His features mirrored Rumi’s: calm brown eyes, the same striking purple hair cropped short and rebelliously styled, paired with a tacky goatee and a goofy smile.
…Was this her father?
— Or: Rumi discovers that Celine has been less than honest about demons, and now Huntrix must figure it out on their own. A Fanfic to explore the magical universe and the girls of KPop Demon Hunters
