What if the hunters's boss is jiu's mother?

i was thinking that too

Maybe she is her aunt ( her mother's sister)...

Yeah thats more logic , if it were her mother she would freak out when she heard she was shot , but knowing she is a half breed and letting the ml love her without punishing like the other couple that was brutally killed , also she wants her alive and that she becomes the leader , probably the aunt avenging her sister
