"uuUU uuUU uuUUuuuuUUUUuuuuuuuUUUUUUU"—Maria Ushiromiya
Maria Ushiromiya (右代宮 真里亞 Ushiromiya Maria?) is Rosa Ushiromiya's daughter. Her father’s identity is unknown. She can’t shake off the habit of speaking like a young child, which often earns her a scolding. She has no interest in studying or making friends, but is very interested in things concerning the occult and black magic. Thanks to her excellent powers of memorization, she knows all kinds of obscure trivia.
A little magician who inherited the black blood from Kinzo Ushiromiya. She has a natural talent Kinzo didn’t have, and even though she’s very young, she reaches the level of magician. Nonetheless, her powers are still very weak and she is just an apprentice. However, her enchanting ability to give magical power to tools is a natural gift, and the magical items she makes are a match even for the master class.
Maria grew up in a lonely environment with her mother being at work most of the time and having no knowledge of her father. Many people thought of her as a pitiful and weird child which she does not understand as she does not know why people think of her as pitiful but instead she thinks that she is very happy. Once, Rosa showed her a photo of a tanned man whom Rosa said was Maria's father. However, when Maria request to see it again, her mother yelled and said that the photo does not exist. After a while Maria starts to doubt who she is and felt not even a teacher was able to answer her many questions.
One day, a priest visited her school and Maria asked the priest whether it is weird to not have a father. The priest then tells her that is not weird and tells her about Jesus was also born from virgin birth. From then onwards, due to misinterpreting what the Bible really means, Maria got back her sense of self with many of her answers answered. This resulted in her believing that she is special and different from other people as well as sparks her interest in the occult.
On a first-grade test during school, Maria was supposed to write the word for "gun" in Japanese. As Maria already knew katakana, she wrote in the characters for "rifle" rather than the hiragana characters for "gun". She was marked wrong for this answer and, as a result, writes almost exclusively in hiragana.
Later, she meets Beatrice when she went to Rokkenjima and became best friends. She taught Beatrice on many occults subjects and magic circles whom she at first looked down upon until Beatrice showed her magic which was actually a sleight of hands. There they created the Golden Land and many new friends.
In Alliance of the Golden Witch, several flashbacks are seen from the perspective of Maria's diary. Those typically involved instances of Rosa and Maria's relationship. After leaving Maria alone for several days, Rosa returns home with presents, one of which is a set of twenty small ceramic animals. Four of the animals, a group of rabbits, became Maria's favorites and later manifested as the Chiester Sisters.
Maria appears as a little girl with short brown hair. She wears a dark corset with a red ribbon over a pink long-sleeve shirt, a black skirt with a pink stripe, knee-high white socks and red shoes. She also wears a small black crown on her head held by a red ribbon tied under her chin. Maria is always seen carrying a pink purse with a large red bow. The One-Winged Eagle is imprinted on the left side of Maria's corset.
Maria is a child of elementary-school age (in the first episode, her mother confirms that she is "nine and a fourth grader"), though usually acts as though she is much younger. This often gets her in trouble with her mother and earns her a slap or two on the cheek. Normally she acts younger than her age but seen as cute by many. But when talking about witches, her personality changes and acts creepily. She also becomes defensive when someone rejects witches and magic which she believes to help her become happy.
She deeply loves her mother and even believes that the abusive and neglectful side of her mother is not her mother but a witch possessing her kind and loving mother to do horrible things despite them both being Rosa. She even went as far as defending Rosa's action in her diary and through Sakutarou's thoughts which in turns are her own thoughts when Rosa is not being a good mother. There are even times when she stated she does not need anyone but just her mother. It is also stated by Willard H. Wright that she never lies.
- In several episodes of the Umineko no Naku Koro ni anime, Maria watches scenes from Higurashi no Naku Koro ni.
- Maria's name comes from the name Mary as in the Virgin Mary from Christianity. This is due to the fact that Maria believes herself to be a virgin birth since Rosa always told her she never had a father.
