Guilty Gear: Strive - Additional Character 2: Jack-O'Guilty Gear: Strive - Additional Character 2: Jack-O'

Jack-O' is an artificial life-form created by Asuka R. Kreutz to prevent the revival of Justice, the herald of destruction.

As Justice was created using Aria, Sol's love interest in the past, as a base, Jack-O' managed to prevent Justice's awakening by fusing with Aria's soul within Justice. It was at this time Aria's soul was fully restored within Jack-O'. However, Aria's consciousness has yet to fully manifest, leaving jack-O' in an unstable state where her personality remains unchanged.

Although she tries her best to be cool and collected in her demeanor, she tends to act child-like when her emotion gets the best of her. For that reason, she wears a special mask to keep her composure during battle.
