Erza, Lucy, and Wendy were all in their swimsuits at a bathing house when they were attacked by Kiria, a dragon eater. The three went on the offensive and tried to defeat the powerful Mage, but that's when something shocking happened

As Erza dodges a few of her attacks, Kiria used her spell, Cutting Strength (which was a form of hypnosis), on her

Erza: Uh?! Wait, was that supposed to do anything? I-?! Erza stopped mid sentence as she looked down at herself Ahh… AAAAHHHH!!! What am I wearing?! This is so embarrassing! She said, covering herself up as she turned beet red.

Wendy: Erza? What's going on with you? You don't act like this.

Lucy: Yeah, we were all in our bathing suits when we started fighting her. What's wrong?

Erza, who was normally stoic, no nonsense, strict, and brave… was now acting timid, shy, embarrassed, and more reserved

Erza: Oh my goodness, I need to change…! This is so humiliating to be seen in this getup…! She says to herself, quivering in fear
