People in this place need to stop gossiping so much and, somewhere, Chikusa is thinning his lips in mild annoyance. At least this doesn't show much in Mukurou, who remains mostly himself as he tries to nip at Ginia's top.

he's too talky
probably just coincidence
those charms can't normally do that kind of thing i think
i just didn't like it

In other words, Hakkai fell unconscious and Chikusa panicked. At least no one died, which is always a risk when it comes to Chikusa being forced to act on a dime to things that freak or annoy him.
