Amy, or "Fischl" as she calls herself, is an investigator for Mondstadt's Adventurers' Guild, accompanied by her night raven Oz. A daring adventurer with seemingly outlandish theories that turned out to be true, she had claimed to hail from a world beyond Teyvat. However, with her coming of age, she is struggling to accept that her childhood dreamworld must give way to the reality of adulthood. Unable to face this alone, she seeks companionship, someone to accept her dual persona.
