Rumi’s Parents Deserve Their Own K-Pop Demon Hunters Spinoff — Here’s Why

K-Pop Demon Hunters didn’t just leave fans with bops — it left them with questions.

Netflix’s record-breaking animated hit, which dropped in August 2025 and quickly became the streamer’s biggest movie ever, delivered a world of pop star demon slayers and jaw-dropping fight scenes. But while Rumi, Mira and Zoey may have ended the film stronger than ever, not every mystery was solved — especially when it comes to Rumi’s parents.

One of the film’s biggest twists reveals that Rumi is half-demon. Her mother, Mi-yeong Ryu, was a legendary demon hunter before her time with Huntr/X, but we learn almost nothing about her past. And as for Rumi’s father? Still MIA — not a name, not a flashback, not even a hint.

While Rumi makes peace with her demonic side by the film’s end, her family’s story is begging to be told. A potential sequel or spinoff could explore the forbidden romance between her mother and the demon who stole her heart, plus give us a look at the original pop star hunter crew, the Sunlight Sisters.

So… who is Rumi’s father?

We know he was a full-fledged demon when he met Mi-yeong, a hunter from the generation before Huntr/X. “Some fans theorize Gwi-ma might be Rumi’s peepaw,” one theory on Reddit suggests, “but he seems completely ignorant of her nature throughout the movie.” Sure, he could theoretically shapeshift into a “sexy hunk” like the Saja Boys, but his total lack of recognition toward Rumi makes that theory pretty shaky.

Is a 'K-Pop Demon Hunters' Sequel Happening? What We Know So Far

And what about Rumi’s mother?

Mi-yeong’s friendship with Celine — Rumi’s mentor and caretaker — hints at some complicated history. “Early in K-Pop Demon Hunters’ development, a concept that wound up being scrapped was that Celine would have secretly killed Rumi’s mother,” artist Simon Baek revealed. It’s not canon, but it definitely adds drama to their relationship.

A Netflix press release once claimed Mi-yeong died in childbirth, but the movie never confirms that. If she’s alive — or existing in some spiritual or demonic form — it would open the door to huge emotional stakes in a sequel.
