“A half-Gear with the blood of ‘Justice’ in her veins. She has an honest and pure heart, but being a Gear lead to a large bounty being place on her head and her life being in danger. Later as she lived an enjoyable life as one of the Jellyfish Pirates, she fell in love with Ky Kiske and they got together(??). Currently she sleeps deep within Illyria Castle, having become embroiled in a certain incident.”
*(The image is a bit unclear so I’m not sure about the ‘get together’ bit. It looks like 結ばれた maybe but I could be wrong?)
We’re still trying to piece together VastEdge’s story, since it’s rather disjointed as far as I’m aware. There’s still no indication that Bardius is a Gear of any kind, yet, since what he summons appears to be Cerberus, rather than simply a Forbidden Beast.
There’s still plenty of loose ends to tie up between GG2, VastEdge, and Guilty Gear Xrd, so you’ll just have to bear with it a bit until we can figure out everything (or at least until Xrd explains it).
