Lightning meets Fang when she and Snow came to aid her and Hope in Palumpolum. They didn't see eye to eye at first, but once Fang tells Lightning her origins and takes the time to check Lightning's brand, Lightning eventually comes to trust her. They bonded over being elder sisters and how they would do everything for their siblings, even tear down the sky if it would save them. - #FinalFantasyXIII #Lightning #Fang
