[[Rosetta_(granblue_fantasy)|Rosetta]] in her swimsuit.

Rosetta's summer outfit first appeared in the 13th episode of the anime. They later released a playable summer version of her using the same outfit a year later (2018). Even some bits of her Summer version's Fate Episode are borrowed from the 13th episode of the anime, notably her priority over sunscreen lotion, and her allusion of sunburn being the "worst enemy" (of the skin).
