I love Ruby, she's one of my oldest original characters! I made her before Osric and Xerxes actually (!) When did SoulCalibur 3 and 4 come out... I remember playing as her with the custom character mode so I must have made her around 2006 / 2008 :)
She used to use a whip and was sort of a cool beast tamer with a 'nightmare circus' aesthetic... She might return to some of that in Skyset Knights, if I want to design an alternate look (I'm toying around with the idea of the characters with multiple 'classes' they specialize in for their adventures. It would be handy for adventurers to know multiple ways to fight, right?)
