As the battle soon started, Ruby tries to get to her cloak near the boulder, swinging Crescent Rose at the Beowolf , she blushed as her breast jiggles and she tries to ignore that her best friend that took a peek at her bouncing breast.

"Jaune! Cover up a bit so I could cover up."

"R-Right."

As the moment of opportunity arrive, she bends down and quickly grab her cloak(which at that moment Jaune manage to yet again see a clear view of her ass) as she wrapped it around herself, finally shielding the view of her naked body from Vomit boy,she felt slightly reassured that now she is finally unexposed.

"That's better." Ruby sigh in relief, now she could fight without exposing much so long as she does move wildly. She now readies herself as more wave of Grimm comes.
