Elphelt Valentine is a major character in the Guilty Gear series. She is one of the Valentines created by the Universal Will, alongside her older sister Ramlethal. Somewhat obsessed with finding a suitable husband, she does not wish to follow her mother's directive of destroying humanity.
Elphelt Valentine was a Valentine created by the Universal Will as a sleeper agent for the purpose of observing Sol until Justice is revived, implanted with several subroutine programs within her subconscious that would activate when the time comes. Shortly after she was born, she was left completely ignorant of her nature as a Valentine and led a relatively normal life.
She eventually became the fiancée of a death metal singer until the day of their wedding, when her programming reactivated and her memories returned. The details are unclear as to what happened, but Elphelt then set out to "rebel" against her mother's orders and raided the Frasco II laboratory, where she acquired various magi-tech weapons from the top-secret Cyprus Project. Afterwards, she used her ability to locate Prime Gear Cells to keep an eye on Sol Badguy, but she found Ky Kiske instead about a month before the events of Sign.
She told him what would happen with her sister Ramlethal, but for security reasons, she was sealed at the Illyrian Special Quarters on the Royal Fleet One.
