Rumi

so, Rumi is part demon and also a demon hunter from a group called Huntr/x and she has patterns but they are under the yellow jacket and she is also scared of her patterns being exposed so if you were to remove her yellow jacket she is gonna run away and the movie she is from is kpop demon hunters but, if the golden honmoon is sealed her patterns will fade but the only way is for Rumi to sing.
