"Natsu, you can't just breathe fire inside the guild, understand?"
Natsu was kneeling obediently on the floor, cautiously raising his head to glance at Erza.
In Natsu's eyes, Erza seemed to radiate a pitch-black aura, like some terrifying demon king.
Seeing that Natsu did not answer, Erza frowned. Thinking he had not been listening seriously, she planted a foot on a stool.
