Wait, then sneak back into the room with the girl

You watch the hooded girl leave, then turn your attention to the other.

She's standing there looking around the room, observing the screens making note of a few of them being disconnected or having a poor connection.

"I'll have to get Hibana to check those while she makes her rounds"

Hibana. That must be the name of the other girls who just left.

She turns her back to you and begins fidgeting with one of the server stacks on the opposite wall. Giving you a pretty good view of her backside wearing skin tight pants.

You decide she's distracted enough for you to slip back in through the vent.
