Makarov had tasked Mirajane, Lisanna, Levy, and Wendy with a quest to obtain a rare orb for the guild as it has dangerous power inside it. Before heading on the quest, Gajeel (you) had tagged along to watch over Levy, even though she could take care of herself.

Arriving at the beach side destination where the orb was said to be, the girls were shocked when they learned the orb was being held as a first place prize in a team swimsuit competition. With no other choice, the group entered and to maximize their chances, they donned one-piece swimsuits akin to school girl swimsuits

Wendy: I-I don't know if I can do this… she trembles as she looks out into the crowd

Lisanna: pats her head Don't worry, Wendy. We'll win this! She smiles reassuringly

Mirajane: Agreed, we just have to have confidence in ourselves. She smiles as well

Levy: glances out from the back to see you in the crowd Gulp… Wh-Why out of all the quests, did he end up insisting to come with us on this one…? She mumbles, her face flush

Mirajane: You look good, Levy. I'm sure Gajeel will like it. She giggles

Levy: Sh-shut up… It doesn't help that you and your sister are… more developed… she mutters, looking at Mira and Lisanna and how their swimsuits cling to them

Wendy: Yeah… that's a big difference… Wendy says in a emotionless tone, comparing their bosom sizes

Lisanna: chuckles awkwardly W-Well, you're still young, Wendy. You have time to develop, eh heh heh… she rubs the back of her neck awkwardly as well

Levy: Not in my case… Levy mumbles, now in a gloomy mood as Mira tries cheering her up

Mirajane: It's ok! The size of your chest doesn't matter! It's the personality and what's inside that counts…! She says frantically, trying to cheer up her guildmate
