I'm pretty sure she existed just for that few minutes to talk to Aqours about what happened with μ's. Might see her face for a bit in cameos we'll most likely never see her in another plot-important role again.

The biggest evidence of this is that she's voiced by a rather well-known seiyuu, Minase Inori. They wouldn't cast well-known seiyuus in larger supporting roles, only minor ones.
