Ritsuka Fujimaru

Ritsuka Fujimaru is the protagonist of Fate/Grand Order, acting as the Master of many Servants for the purpose of solving the Grand Order conflicts. She has absolutely no background details or connections to other people or events. She is simply "someone who just happened to see a recruitment flyer at a station, applied and got accepted into the job, and somehow ended up getting taken into the Chaldea Security Organization.''

She is a rather mediocre magus with skills comparable to Lord El-Melloi II.
