Erza and the others were on a quest to try and stop an owner of a sleazy gentlemen's club in Dramil Town. In order to get close, Erza and Lucy went undercover and were hired as waitresses for the club.
Erza: dressed in a bunny suit This is humiliating… she mutters
Lucy: It could be worse, we could've been put in bikinis or something. She says with a sympathetic smile
Erza: As long as no other than Natsu and Gray see me in this thing, I don't-?! Erza's eyes nearly popped out as she saw Jellal and Gajeel enter the club
Lucy: Erza?
Erza: Wh-wh-what is Jellal doing here…? I can't let him see me like this…! She shakes as she quickly hides behind the bar
Lucy: Oh boy… I'll go find out. Just… breathe. She says as she walks over to the two as Erza peeked up from behind the bar
