Jack the Ripper

Jack the Ripper is an Assassin-class Servant in Fate/Grand Order, depicted as the collective spirit of children who died in the slums of Victorian London. This interpretation takes the form of a young girl seeking the warmth of a mother.

Jack the Ripper as the Assassin-class spirit

Childlike, affectionate, and disturbingly casual about killing, Jack reflects innocence twisted by abandonment and violence. She often calls a chosen Master or guardian "Mother," expressing a need for belonging rather than a conventional criminal motive.

Abandoned children, mist, and the search for a mother

Jack uses knives, mist, concealment, and the Noble Phantasm Maria the Ripper, which is especially dangerous under specific conditions. Her identity differs sharply from other Fate versions of Jack the Ripper and should be treated as the female Assassin incarnation.
