Caster is "Nursery Rhyme" (ナーサリーライム, ?), the embodiment of Alice's feelings on the subject projected onto a Reality Marble, Nursery Rhyme, to create a pseudo-servant. It is not a hero in the traditional sense, but the general term for any picture book that managed to manifest itself into a corporeal existence. It is a genre deeply loved by the children of England that came into being as a reaction to the half-voiced dreams of the young. It eventually emerged as a Servant who came a champion of the innocent. It formed the foundation for the book Alice in Wonderland, what was perhaps the best known work from the author known as Lewis Carrol, which began as a series of simple rhymes told to the daughters of a family friend while rowing down the River Thames on a warm summer's day.
Nursery Rhyme does not have its own body, and it manifests itself as the will of its current Master. Caster is Alice's identical twin in terms of her appearance; however, Caster's primary colors are black and purple in contrast to Alice's white and blue.
Caster 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.
Caster is the enemy that Hakuno's Servants has to face in the third round. She appears when Alice talks about her past history, Caster summon Jabberwock to fight. Hakuno Kishinami and the servant first thought that Jabberwock was the servant and a Berserker class. Throughout the week, they convince Hakuno to "play games" with them, noting two people named Yamada and Suzuki as previous "playmates." In the second floor, Caster unleashed her reality marble Nameless Forest against Hakuno and the servant. As Hakuno managed to catch up to Alice and Caster, Hakuno existence started to fade while Caster and Caster teleported away. Hakuno successfully broken the reality marble by remembering her name. Caster comforts Alice saying there are other games that they can play with Hakuno.
Touko Aozaki helps analyze Alice's servant explaining that a Berserker class cannot utilize a reality marble and a caster class is more suitable. As Hakuno look up more details about Jabberwock, Alice pops up and Hakuno asked if Jabberwock is her servant. Caster interrupts their conversion before Alice reveals anymore details, and Hakuno figured out the true class of this servant. Alice and Caster both revealed Nursery Rhyme existence.
In the elevator, Alice claims that she doesn't need Hakuno anymore and Caster is the only person, she'll ever needs. As they're about to be deleted, Caster laments for her defeat and clings onto Alice. Caster blames on Hakuno for taking away her happiness with Alice, but Alice accepts that everything has to end someday. Alice thanked Caster and fades away, Caster cries out knowing that she wouldn't be happy without Alice and fades away as well.
In Chapter 6, there are many Caster clones.
She is an irregular Servant created from the dreams of her master with the relic known as "Perpetual Engine - Maiden Empire". Caster's abilities are linked to Alice due to their unique nature through Nursery Rhyme. Their main Noble Phantasm is The Queen's Glass Game, and they can create the Jabberwock and Nameless Forest. Caster uses physical strikes in battle despite her frail-looking nature. She uses The Plains of Winter (冬の野の白き時, ?), an ice attack spell, Frenzied March Hare (三月兎の狂乱, ?), a wind attack spell, and White Queen's Enigma (白の女王様のなぞなぞ, ?), an enchantment that lowers the enemy's magic resistance when she makes certain strikes.

Kewords English | Japanese
01 - Maxwell's Demon - Maiden's Empire: Queens Glass Game
"A story without end,
A child-like finger returns to the first line,
A tiny hand reaches out for the second volume,
For as long as the reader denies reality."
02 - Jabberwock
"Names to be uncovered and places still unknown.
Fire breathing dragons and cloud sprouting giants,
and magicks that are monsters in the shadows.
Maybe, just maybe, the words of adults are lies.
The truth of it all is in Professor Dodgson's mind."
03 - Nameless Forest
"Ackroyd and Celluloid;
No one is especially special here,
Birds are birds and people are people,
Entropy suits me to a tittle,
In the end, your name is mine."
Skills English | Japanese
01 -Transformation [A+]
"I will change, I have changed.
I am you, while you are me.
I'm going to change, I will have changed.
I am you and you are me."
02 - Metamorphosis [A]
"This is the ability to merge one's own body with the body part of others. The higher the ranking of this skill, the further away one becomes from being considered as a true hero. But it do-do-doesn't matter doesn't matter that kind of stuff doesn't matter at all!
Whatever you say needs to be done I will do as you order me to!"
03 - Territory Creation [A]
"The smallest door, the maddest tea party,
The checkered board in the rainbow meadow,
the riddles of the chatty twins,
But my favorite of all can only be this one,
The invitation to the nameless forest,
where all can be forgotten!"
Details English | Japanese
01 - Character Background
"A nursery rhyme is a children's refrain,
Tom Thumb's charming picture book,
The first glimpse of Mother Goose's awakening,
The sorrowful me to the lonely you,
Your final wish, let's make it true."
02 - "Nursery Rhyme"
Nursery Rhyme is not a hero in the traditional sense. Rather, it is a general term for any picture book that has managed to manifest itself into a corporeal existence.
The genre itself, deeply loved by the children of England, came into being as a reaction to the half-voiced dreams of the young and eventually emerged as a Servant who came a champion of the innocent. It formed the foundation for perhaps the best known work from the author known as Lewis Carroll. His book "Alice in Wonderland" began as a series of simple rhymes told to the daughters of a family friend while rowing down the River Thames on a warm summer's day.
The Servant Nursery Rhyme is actually a type of Reality Marble. It projects the true feelings of its Master and creates a pseudo-servant in a form imagined by the one who summoned it.
