K-Pop Demon Hunters Fever: How Netflix’s Hit Film Is Taking Over Halloween 2025

If you’ve spent a fortune — or, as some might say, a severed arm and leg — stocking up on Halloween candy this year, don’t be surprised when dozens of tiny Rumis and Jinus show up at your door demanding treats.

For anyone wondering who those are, Rumi and Jinu are the heroic duo from K-Pop Demon Hunters — now officially the most-watched film ever on the world’s biggest streaming platform.

From Screen to Sidewalk

According to Google Trends’ annual “Frightgeist” report, which tracks the most popular Halloween costumes each year, KPDH characters dominate the charts in 2025. The top five fastest-rising costumes nationwide are all inspired by the movie’s colorful demon-slaying idols.

Retail giant Spirit Halloween, the exclusive seller of official K-Pop Demon Hunters merchandise, confirmed that demand has been off the charts. Its shelves have been cleared of the signature purple wigs and yellow jackets that mirror the film’s protagonists, The New York Times reported.

With the movie now surpassing 325 million views on Netflix, it’s little wonder searches for “K-Pop Demon Hunters costume” have skyrocketed more than 1,100% over the past three months. The phenomenon underscores how much pop culture continues to shape our collective Halloween imagination.

When Movies Drive the Dress-Up

Data from Google Trends shows that costume popularity consistently mirrors major movie releases. Last year’s Barbiecraze saw a flood of pink-clad revelers, just as Despicable Me 2 and It inspired waves of Minions and Pennywises in years past.

Franchises like Super Mario and Minecraft also enjoy costume resurgences when their video game worlds hit the big screen. Yet, even with the rise of viral trends, traditional Halloween favorites — ghosts, vampires, witches, and superheroes — never seem to fade.

Because while pop culture may redefine what’s “in,” October 31 always leaves room for the classics.
