The world knows them as a viral K-pop group named HUNTR/X. In reality? They are a trio of demon hunters chosen specifically for their singing voices to maintain the Honmoon, the barrier that protects the world from demons. The premise might sound a little strange at first, but KPop Demon Hunters is wonderfully creative from start to finish.
KPop Demon Hunters follows Rumi (Arden Cho, singing voice: EJAE), Zoey (Ji-young Yoo, singing voice: Rei Ami), and Mira (May Hong, singing voice: Audrey Nuna) to the final show of their current HUNTR/X tour, where a giant crowd of fans have gathered to watch them sing. As they are set to arrive on-stage, their manager Bobby (Ken Jeong) sees their location steadily moving away from the concert location—leading HUNTR/X to realize their plane had been hijacked by demons. Easily dispatching them, they arrive just in time to their show. After they perform their last song, they’re delighted to see a glint of gold over the Honmoon. Their job in particular is to turn the Honmoon completely gold with their songs, strengthened by the power of their fans—sealing demons away from the world for good.
Zoey and Mira in particular are excited for their time off, but Rumi doesn’t seem to be—announcing their new single before the other two even get a chance to sit down properly. Their break is cut wildly short as they prepare for the debut and release tour. However, they quickly run into an obstacle—as they begin recording, Rumi begins to lose her voice. As Rumi walks into the changing room and unzips her jacket, Rumi is shown to be part-demon despite being a demon hunter. Her demon marks, which have only spread over time, have now reached her throat—causing the voice loss she’d experienced while recording their song. Her earlier workaholism was a push to make things right—having been promised that her marks will disappear when the Honmoon is made gold and the demons are permanently cut off.
To make matters worse, a demon named Jinu (Ahn Hyo-seop) has proposed to the demon king Gwi-Ma (Lee Byung-hun) his plan to fight back against the demon hunters—create a K-pop boy band known as the Saja Boys to steal HUNTR/X’s fans and weaken the Honmoon. Since the Honmoon was created, Gwi-Ma has only gotten weaker as demons were no longer able to steal human souls for him. In exchange, Jinu asks that Gwi-Ma erases his human memories. The Saja Boys are an immediate hit in the human world and only HUNTR/X are aware of their true natures as demons.
When K-pop superstars Rumi, Mira and Zoey aren't selling out stadiums, they're using their secret powers to protect their fans from supernatural threats.
