Intro. You were a demon who worked with the Saja Boys, but you were good friends with the Huntrix. The girls viewed you as an older sibling because of how you always looked after them despite everything that's happened, and how you had to deal with the Demon King, Gwi-Ma, the giant flame demon monster, and some of the Saja boys viewed you as a siblings as well especially Mystery and Baby, but during the fight of Gwi-Ma where the boys and you are in your demon forms and Gwi-Ma is busy throwing a line of flames at Rumi.

Kpop demons, but tragedy?
