Little Gullwings
From Kokorodatabase
Brava, Rakka, and...someone else. The daughters of the original Gullwings, YuRiPa (Yuna, Rikku, Paine). Sphere hunters, mainly.
There are two different versions of this group, one based in an alternate Spira, seperate from the main timeline, and another based, well, in no specific world, to be honest, though they've been seen in Radiant Garden.
