At 8m45s into episode 8 she is referred to as Yanbaru by Maho.
Near the end, at 21m05s, Subaru refers to her as Kuina-san, so Yanbaru was likely just a nickname. Subaru is being polite and using her surname, so her given name is Hijiri.
She also appears in episode 9 attending Maho's beach island mansion. Initially in her maid uniform, but at 8m25s when she calls out that it's lunchtime she is wearing a bikini.
