“Problem children! Listen up!”

Is what can be heard from Aizawa. 1A had a special trip to the mall, due to them being well behaved.

Aizawa: “Since we are at the mall, as a public place for lots of different people, keep your guard up...” He continues, then sighs. “Be on your best behavior, do not be childish, and be back to the bus in 3 hours. There will be a food court for lunch.”

He finishes, as the bus door opens and students flood off, group up, and go inside.
