In a modern world where demons feed on human souls and music serves as a protective magical barrier called the Honmoon, the K-pop girl group HUNTR/X leads a double life as demon hunters descended from ancient Korean shamans. When the demon overlord Gwi-Ma sends his lieutenant Jinu to form a rival boy band called the Saja Boys, the groups clash both on stage and in the supernatural realm. Lead singer Rumi harbors a dangerous secret—she is half-demon—and as the Saja Boys drain fan souls and weaken the Honmoon, her fear of exposure causes her to lose her voice. The crisis deepens as Rumi and Jinu form a complicated bond over shared guilt and hidden truths. When Rumi's secret is exposed and trust fractures within HUNTR/X, Gwi-Ma launches a full assault during a massive concert. Rumi must embrace her true self, and with Jinu's sacrifice, HUNTR/X reunites to perform a new song of self-acceptance and unity, defeating Gwi-Ma and forging an unbreakable barrier.
Style
An animated musical urban fantasy blending K-pop aesthetics with Korean folklore. Expect vibrant color palettes, dynamic concert sequences, and stylized action choreography that fuses dance with supernatural combat. Musical numbers drive both the narrative and the magic, with songs serving as literal spells. The tone balances high-energy pop spectacle with emotional depth, exploring themes of identity, self-acceptance, found family, and the weight of hidden truths. Visual and narrative inspiration draws from both modern music performance films and traditional Korean mythological imagery.
Setting
A vibrant urban fantasy version of modern Seoul and beyond, where the glittering world of K-pop entertainment collides with traditional Korean folklore and shamanic mythology. Stadiums pulse with lightstick oceans and synchronized choreography, while beneath the surface, ancient demons lurk in the shadows. The Honmoon—a magical seal powered by music and the emotional connection between performers and fans—holds back the demon realm. Neon-lit concert venues, recording studios, dance practice rooms, and backstage corridors coexist with spirit realms, sacred shrines, and the dark domain of Gwi-Ma. The supernatural bleeds into the mundane: talismans hidden in accessories, protective wards woven into stage designs, and ancestral spirits watching from the margins.
Characters
Rumi
The lead singer of HUNTR/X and a descendant of ancient demon hunters. Outwardly confident and charismatic on stage, Rumi secretly bears demon skin markings that she hides beneath her idol styling. She is half-demon—a truth that fills her with shame and fear of rejection. As the Saja Boys threaten the Honmoon, the pressure causes her voice to falate and weaken. Her journey is one of self-acceptance: learning that her dual nature is not a curse but a source of unique strength. She forms a complex, emotionally charged connection with Jinu, who understands what it means to live with guilt and hidden darkness.
Mira
A member of HUNTR/X and a skilled demon hunter in her own right. Mira is dedicated, fierce, and deeply loyal to the group's mission and to her fellow members. She takes the supernatural threat seriously and struggles when trust within the group is shaken by Rumi's revealed secret. Her arc centers on learning to see beyond betrayal to the person beneath.
Zoey
The third member of HUNTR/X, rounding out the trio of idol demon hunters. Zoey brings her own personality and strengths to the group's dynamic, both in performance and in battle against demonic forces. Like the others, she must navigate the fracture in trust when Rumi's half-demon nature is exposed and choose whether unity or division will define HUNTR/X.
Jinu
Gwi-Ma's right-hand demon and the architect of the Saja Boys, a rival K-pop boy band designed to drain fan souls and weaken the Honmoon. Centuries ago, Jinu sold his own soul—a decision that has haunted him ever since. He is charismatic and calculating on the surface, but carries deep guilt and weariness beneath. He forms a complex bond with Rumi, recognizing in her a kindred spirit caught between two worlds. Ultimately, Jinu sacrifices himself to help HUNTR/X defeat Gwi-Ma, redeeming himself in a final act of courage.
Gwi-Ma
An ancient and powerful demon overlord sealed behind the Honmoon for generations. Gwi-Ma seeks to shatter the barrier and feast on human souls once again. He is manipulative, patient, and immensely powerful, using the Saja Boys as his instrument to undermine HUNTR/X from within. He exploits doubt, fear, and division, waiting for the moment trust breaks to launch a full-scale assault during a massive concert. He is defeated when HUNTR/X channels self-acceptance and unity into a new, unbreakable seal.
The Saja Boys
A rival K-pop boy band formed by Jinu under Gwi-Ma's command. Composed of demons disguised as charismatic idols, the Saja Boys use their music, charm, and performances to drain the souls of unsuspecting fans and weaken the Honmoon barrier. They serve as both musical rivals and supernatural antagonists to HUNTR/X, weaponizing the same power of fan connection that HUNTR/X uses for protection.
Locations
Seoul Concert Stadium
A massive stadium venue in Seoul that hosts HUNTR/X's world tour performances. Beneath the dazzling lights, pyrotechnics, and oceans of fan lightsticks, the stadium doubles as a battleground between demon hunters and supernatural forces. The Honmoon barrier is anchored and reinforced here through performance. It is the site of the climactic confrontation with Gwi-Ma.
HUNTR/X Studio and Hideout
The group's private rehearsal space and base of operations. One part recording studio and dance practice room, one part armory of shamanic tools and demon-hunting equipment. Talismans line the walls alongside gold and platinum records. This is where HUNTR/X trains, prepares, and navigates the personal tensions that threaten to tear them apart.
The Demon Realm
A dark, twisted dimension where Gwi-Ma and his demonic forces dwell, sealed behind the Honmoon. It is a place of shadows, corrupted landscapes, and ancient malevolence. The barrier between this realm and the human world grows thinner as the Saja Boys weaken the Honmoon.
The Sacred Shrine
An ancient Korean shamanic shrine tied to the lineage of the mudang and the origins of the Honmoon. It holds ancestral spirits, forgotten rituals, and the deep history of the demon hunters' sacred duty. It serves as a place of revelation and connection to the past.
Objects
The Honmoon
A magical protective barrier sustained by music and the emotional bond between performers and their fans. The Honmoon seals the demon realm away from the human world. It grows stronger when HUNTR/X sings with genuine heart and connection, and weakens when that bond is corrupted or broken. The climactic performance forges a new, unbreakable version of the Honmoon through self-acceptance and unity.
Rumi's Concealing Talismans
Magical talismans and styling tools Rumi uses to hide her demon skin markings from the world. They represent her shame and fear of exposure—and the moment they fail or are removed becomes a turning point in the story. Embracing her markings without concealment is key to her growth and to the final victory.
Shamanic Hunting Tools
Traditional Korean shamanic weapons and artifacts modernized for use by HUNTR/X. These include blessed microphones, talisman-infused accessories, ward-embedded stage equipment, and ritual items disguised as everyday idol gear. They bridge the ancient mudang tradition and contemporary K-pop performance.
Lightsticks
HUNTR/X's official fan lightsticks, which serve a dual purpose: they are both concert merchandise and conduits for fan energy that helps reinforce the Honmoon. When fans wave them in unison during performances, their collective emotion strengthens the magical barrier against demonic forces.
