"Nursery Rhyme", Class Name Caster, also called Alice, is the Caster-class Servant of Alice in the Moon Holy Grail War of Fate/EXTRA. She is one of the Servants of Ritsuka Fujimaru of the Grand Orders conflicts of Fate/Grand Order. Nursery Rhyme does not have its own body, and it manifests itself as the will of its current Master. Nursery Rhyme is Alice's identical twin in terms of her appearance; however, her primary colors are black and purple in contrast to Alice's white and blue. In Fate/Grand Order she retains the same form as she had in Fate/EXTRA, to honor Alice's wish to play with others and to remember her by. Supposedly, the height and weight belong to its human form. An alternate version of her summoned by Minamoto-no-Raikou resembles a younger version of Raikou wearing a kimono with long sleeves. Nursery Rhyme is the mirror image of Alice with the same personality, but she truly cares about her Master and doesn't want to lose her. Unlike Alice, she is not shy, only emotionless and bored. She claims that being Alice's Servant makes her happy, and being the Servant of another wouldn't be the same. She feels somewhat guilty about retaining Alice's form in Fate/Grand Order, but after Ritsuka helps her confront those feelings she hopes that through her Alice will experience the happy ending she never received in life.
