K-Pop Content Takes Over Halloween Culture... Rumi’s Costume Ranks #1 in the U.S.

K-pop style characters have become the stars of the Halloween season. According to Google’s Halloween search trend analysis system, “Frightgeist,” Rumi, the protagonist of Netflix’s animated series “KPop Demon Hunters,” was identified as the most popular Halloween costume search term in the United States for 2025. “KPop Demon Hunters” is a series that combines the aesthetic elements of K-pop idols with supernatural action, featuring three main characters—Rumi, Joy, and Mira—who serve as K-pop style performers while also fighting demons at night. Rumi appears as the lead vocalist and protagonist of this team. Her signature look consists of purple mohawk hair, denim shorts, a white cropped top, a yellow cropped jacket, and combat boots, and this distinctive visual style has received widespread acclaim from people across the U.S. Per Google Frightgeist data, not only Rumi but also other characters from the same series such as Joy, Mira, Jinwoo, Baby Saja, and Duffy the Tiger made it into the top 25 most popular Halloween costumes in the U.S. for 2025. Regionally, cities like Mobile, Birmingham, and Huntsville in Alabama ranked Rumi’s costume among the highest searched terms, with half of the top 5 trending costumes being characters from “KPop Demon Hunters,” demonstrating its extreme popularity. Meanwhile, active developments continue within the domestic K-pop scene as well. The global K-pop chart “KM Chart” is conducting a September 2025 K-music preference survey through the 24th, with 50 songs across various genres such as TOMORROW X TOGETHER’s “Beautiful Strangers,” BLACKPINK’s “Luteo,” aespa’s “Dirty Work,” and Im Young-woong’s “Make a Moment Last Forever” competing for spots in the K-music category. Thirty groups, including BTS, STRAY KIDS, aespa, Lee Chan-won, and TOMORROW X TOGETHER, are on the list for the K-music artist category, with ten groups each competing in the male and female rookie awards categories.
