Jack-O'

Valentine Jack-O' Servant of That Man Jack-O' Scales of Juno Jack-O'

Story
Jack-O' Valentine, more commonly known as simply Jack-O', was formerly That Man's third servant, who first appeared as a wanted criminal on her own. Jack-O' has mischievous attacks, utilizing Jack O'Lantern-themed weapons such as explosives. She wears a mask during a battle. Because her awakening remains incomplete, she can't function without her mask and toffee. Her past is shrouded in mystery, and her own memories are vague. Because she's in an unstable state, the tone of her voice and personality changes rapidly. One of her personalities has an intellect as the late-Aria and has a part of Justice. In the end of the story, Jack-O' sacrifices her life to save Elphelt, by switching place as Justice's vessel, thus saving the world and reviving Aria, thwarting Ariels' evil plan. However, according to Raven, there can be multiple Jack-O' Valentines somewhere who can take the place of the first Jack-O'.
