KPop Demon Hunters voice cast: All the stars behind the characters

The animated musical KPop Demon Hunters has turned its neon‑soaked blend of K‑pop, fantasy, and action into a global Netflix hit since dropping on June 20, 2025. The story follows HUNTR/X- Rumi, Mira, and Zoey, whose chart‑topping tours double as covert demon‑slaying missions against the rival Saja Boys.

A stacked ensemble of Korean and Korean‑American talent powers KPop Demon Hunters, adding genuine pop‑culture credibility to every line and lyric. Below is a character‑by‑character guide to the voices, complete with key roles, career highlights, and a few words from the stars themselves.

KPop Demon Hunters' voice cast explored

1)Arden Cho as Rumi

Rumi fronts HUNTR/X with powerhouse vocals and big‑sister energy, yet hides fears that her “perfect” image might crack. Cho, born in Amarillo, Texas, broke out as Kira on Teen Wolf and recently headlined Netflix’s Avatar: The Last Airbender live‑action series. As per Entertainment Weekly's exclusive interview report dated May 22, 2025, Cho said,

“She wants to encourage the girls to, obviously, be awesome rock stars and hunt the demons while covering this deep, dark secret and trying to overcome all of her struggles.”

2) May Hong as Mira

Mira wields a supernatural polearm and the attitude to match. Hong’s credits range from HBO Max’s Hacks to Netflix’s Tales of the City. As per Entertainment Weekly's report dated May 22, 2025, Hong called Mira,

“She's tough as f---, I like that, but also so sensitive and so vulnerable. I do think I've been perceived as someone who's harder on the outside than I actually am with loved ones, and so it resonated with me.”

A duality of the character she related to personally.

3) Ji‑young Yoo as Zoey

Zoey is HUNTR/X’s bubbly rapper and resident maknae. Yoo gained notice in Prime Video’s Expats and the indie thriller Until Dawn. Recording Zoey’s rapid‑fire verses proved exhausting. She told Entertainment Weekly on May 22, 2025,

“A lot of it was just me trying to get as much energy as possible stored up in my system so that I could go into the booth and give that much energy to her voice, which is a ton of fun, but definitely a new kind of stamina challenge for me.”

4) Ahn Hyo‑seop as Jinu

Heart‑throb Jinu leads the Saja Boys. The Seoul‑born actor starred in K‑dramas Business Proposal and A Time Called You. KPop Demon Hunters is his first English‑language voice role. In a Netflix promotional clip in July 2025, Ahn said,

“I liked [Jinu’s] looks and how he’s kind of cool.”

5) Ken Jeong as Bobby

Bobby juggles tour logistics and demon emergencies as HUNTR/X’s frenzied manager. Jeong swapped medicine for comedy, exploding in The Hangover trilogy before becoming a fixture on Community and The Masked Singer.

6) Yunjin Kim as Celine

Celine, mentor, ex‑idol, and former demon hunter, adopted Rumi after tragedy. Kim is synonymous with Sun‑Hwa Kwon from Lost and recently appeared in Netflix’s XO, Kitty.

7) Lee Byung‑hun as Gwi‑ma

Lee’s resume spans Hollywood action (G.I. Joe films) and Korean hits like Squid Game, where he plays the ominous Front Man. In KPop Demon Hunters, he lends gravitas to Gwi‑ma, a demon king plotting global domination.

8) Daniel Dae Kim as Healer Han

When Rumi loses her voice, the group turns to the unconventional Healer Han. Kim, another Lost alum, has voiced characters in Avatar: The Last Airbender and starred in The Good Doctor.

9) Liza Koshy as Talk‑Show Host

Digital‑native star Koshy cameo‑hosts the band’s surprise “Golden” comeback interview. She previously fronted Nickelodeon’s Double Dare revival, earning a Daytime Emmy nod.

10) Joel Kim Booster as Romance Saja / Idol Show Host

Booster voices a scene‑stealing Saja Boys member and a variety‑show MC. His breakout came with Hulu’s Fire Island, followed by Apple TV+’s Loot.
