Guilty Gear Xrd will have another Kiske in town when it launches -- Sin -- the son of Ky and Dizzy. He has a special modifier called "Full Stomach," that lowers a bar with every special move -- you have to eat food to recover it.
For reference, Ky is representative of holy elements in the Guilty Gear franchise and devotes himself to God, and Dizzy is a demon-like entity (though she is kind, seeing as that she's roughly eight years old in human years) that is half-human with a fast-aging body. Sin was part of the lore and found previously in Guilty Gear 2, but this will mark his 2D competitive fighting debut (Xrd is technically 3D, but plays like a 2D game nonetheless).
It's possible that Dizzy could have aged a bit more by the events of Xrd, but it's just...weird, even for Guilty Gear standards. He sounds really fun to play though.
