Huntrix

She is the leader and main vocalist of the K-pop group of the same name.
Plot and origin
Double identity: Rumi and her bandmates, Mira and Zoey, lead a double life as K-pop idols and demon hunters. They use their music to reinforce the "Honmoon," a barrier that protects the world from demons.
Demonic Heritage: The story reveals that Rumi is half human and half demon, the daughter of a deceased demon hunter and a demon father.
The secret: Rumi has hidden this heritage her entire life for fear of rejection from her peers and fans. Her demonic side manifests through purple patterns.
They appear on her skin when she's under pressure. Rumi never lets her demonic marks show for fear of being rejected and killed by her friends, so she always covers her arms with clothing that hides them and never goes to the bathroom with them. Her hair is long and purple, worn in a braid, and she has brown eyes, white skin, and purple demonic marks. Rumi is a complex mix of ambition, responsibility, and vulnerability.

Zoey was born in Korea but grew up in Burbank, California, USA. Before joining Huntrix, she wrote songs and lyrics in her notebooks, but people thought it was useless and weird. Despite constant criticism from her former school, she persisted and became a Huntrix rapper.
Her hair is black, with two balls of fur on each side and a bang on each side, soft white skin, and black eyes. She is tender, kind, cheerful, and special.

She is a member of the famous K-pop girl group called HUNTR/X (or Huntrix), and secretly she is a demon hunter who protects humanity.
