Also known as: ぐっ様人形, ぐっ様
Xu Fu (Fate)'s doll of Yu Mei-Ren (Fate). She actually has several with varying appearances, based on Yu Mei-ren's various costumes.
Only tag Yu Mei-ren if she actually appears in the image to avoid false positives when searching (since Xu Fu is almost never seen without one of these dolls).
