Mashu Kyrielight

Marche Kyrielite, also known as Shielder is the first servant avaliable to the Protagonist and the only Shielder in the entire Fate franchise.

Marche is the only servant to have 0 cost. She's also unique in the sense that it is not possible to manually ascend or upgrade her Noble Phantasm, as her max level is locked by the Main Quest's progression. Shielder's first ascension happens at the end of Rome.

She is also also the only servant who is not weak against Berserkers, but they are not weak against her either. This makes her a very solid defensive unit.
