Ginnu

-400 years ago, Jinu was an ordinary man, poor. Because of this, he made a deal with the demon king Gwi-Ma, promising his soul in exchange for an incredible voice and fame.
This led to his transformation into a demon, exile, and eternal slavery to Gwi-Ma.
-Guilt and revenge. Jinnu feels a terrible sense of guilt because the deal has brought his family back into poverty.
-Gwi‑Ma amplifies his emotions ("controls through voices of shame and despair")
-Liberation through the witch-group
With the arrival of Huntrix comes the chance to use the Saja Boys as a tool: to destroy Honmoon, release the demons, and perhaps free themselves from Gwi-Ma's control.

Break the Honmoon (magical barrier). Together with Gwi-Ma, he organizes the creation of the boy band Saja Boys to suck out the fans' energies during concerts and break the barrier. This will allow demons to enter the human world, in accordance with the deal he made with Gwi-Ma.

Brunette (black hair) with purple symbols on his body (in battle form).
-A black Asian-style stage costume decorated with demonic symbols.
-Glowing golden eyes (in demon form). And brown eyes in human form.
-On stage, a handsome idol. In battle, a real demon.

• Charm. Cleverly manipulates the public's attention.
• Dark nature. Uses music for magical rituals.
  -Intelligence. Smart, strategic, does not act impulsively.

The handsome, charismatic leader of the boy band Saja Boys, rivals of the main characters of Huntrix. At first glance, he is the perfect idol:

• a charming smile,
  -cold magnetism,
  -perfect dancing,
  -millions of fans.
  But there's something dark beneath the surface: he's a demon and the leader of a band that literally sucks the energy out of its fans through their songs, fueling an ancient force that threatens the magical balance of the world.
