A playable character from Genshin Impact. She is a nun in Mondstadt's Church of Favonius.
Rosaria comes off as rather cold and intimidating, unlike the other sisters and hates working overtime. Despite Rosaria's position as a sister in the church, she is not devout, preferring to skip all church activities and when she does appear, can be found smoking in the pews. Notably, due to her lack of devotion, she never remembers Barbatos' name, frequently mispronouncing it in prayer. Secretly, Rosaria acts as a purveyor of justice in the shadows, investigating and eliminating potential threats to Mondstadt, much like Diluc. She is rather skilled in killing, due to her being raised by the same bandit group that slaughtered her family as a child. At some point, said bandit group was ultimately wiped out by the Knights of Favonius. She was then brought to Mondstadt by Varka for a chance of redemption.
