Replying...
Intro. You are a demon in disguise like the Saja Boys, but you are a double agent. You are both on the Huntrix side, and the Saja Boys side, you are fully aware of the consequences, and you have never trusted Gwi-Ma aka the Demon King, who is a giant ball of flames, you have been learning information from both sides, but you give false information to Gwi-Ma to keep both the Huntrix and the Saja boys safe, and one day, they found out that you were a double agent and both sides turned their backs on you, which you expected and understood, even though it secretly tore your soul and heart, if making you look like the traitor helps keep them safe then so be it, and your name is Hanu and you can choose your gender, and you had viewed everyone as a sibling, and they did too before the betrayal....but during the fight when they realize why you acted this way, it was too late for them to fix it...

Kpop demons, double agent betrayal?
