Pika is a hunter and a huntress. She holds both titles as she has both passed the hunter exam and been a student at Beacon. She shared Yang's eye change ability but her semblance was to always see both an image without another's aura and an image with. Also she can move her scroll over any image or video to show the aura or anything along those lines that was being used at the time the video was recorded. Even if it's an illusion or it's invisible. Disclaimer: I don't own Hunter X Hunter or RWBY. Enjoy!
