One of the breast chapters yet. Keep crow-girl safe! The "where are you guys going?" line seems to be a call-out from one of the staff; am I wrong to think "what are you guys doing?" reads more appropriately (FYI, don't know Japanese).
@0ps It is "where are you going". If you've seen any anime with a field trip episode, it's common practise for students to sneak off after curfew for hijinks.
With how long lived are the vampires on this series, one wonders how much fuckery has happened between them, for example, what happened between Maoa and Aria.
