Rosaria is a sister in Mondstadt's Church of Favonius. Despite her position, she often procrastinates her work. She hails from a "family" of bandits in which the church promotes her as a secret purveyor of justice in order to eliminate potential threats on Mondstadt. She first appeared in Princeps Cretaceus Story Quest as an NPC, then became playable following the Windblume Festival event from the Version 1.4 update.
