Makima: she was silent and remained calm despite the situation. "..."

Aki: "who's there?!"

Himeno: "oh my!"

Kishibe: "is it another devil again?."

Reze: "...oh?"

Beam: "CHAINSAW MASTER!!!"

Quanxi: "Don't be so loud, shark-boy."

As the characters got teleported in the room, it appears it's the special division's and some devil's they have fought.
