Miu Ueno

Miu Ueno is a main character in Yu-Gi-Oh! RED. She is a student of Duel Academia enrolled in the Osiris Red Dorm. She is a spirit seer with a special connection to Madolche Mewfeuille, as well as a dimension walker.

Appearance
Miu is a short, skinny girl with short cropped white hair that seems to have permanent bedhead. She is light skinned and has warm brown eyes. As a first-year, she wears a cropped Osiris Red jacket over a dress shirt with long sleeves that drape over her hands, and a red skirt with black leggings and red boots. As a third-year, Miu only grows a little bit taller, and her hair is a little more styled, with purple barrettes holding part of her bangs back. She now wears the third-year's jacket, a long tailed jacket that is white with red trim, over a long purple hoodie, black leggings, and brown boots with white pom poms.

Personality
Miu is eternally sleepy, always looking forward to her next nap. She isn't the best at socializing, preferring to keep to herself and let others come to her if they want to talk, though she may be annoyed if she's interrupted. She likes to spend time cuddling and napping with her monsters, and has a particular love of sweets. Over time, she starts to become more interested in having friends, and starts to really enjoy being able to spend time with others, provided that she isn't expected to do much talking. Despite being more reserved, Miu is very loyal to those she calls friends, and has no trouble standing up for herself and others, rarely caring what anyone thinks of her because of it.

Abilities
Miu is a spirit seer, meaning that she can see, hear, and sense Shadow People when they manifest spiritually in the physical realm. Her sight is very clear, and she can even experience some tactile sensation when interacting with her monsters, despite them not being solid.

Miu is also a dimension walker, meaning that she has the ability to walk between worlds. She is not quite as skilled at this, sometimes walking into the wrong world and not being sure how to get back, and so tends to save her skills for when they are absolutely necessary.

Etymology
Miu's first name is written in hiragana, which has no particular meaning. Her surname, Ueno, is written 井上, from 井 (town) and 上 (up).

History
Miu grew up in Sapporo with a single mother. She grew up being able to see duel spirits and being surrounded by Madolches who were attracted to her abilities. When she was young, she wrote a letter to Pegasus explaining the Madolche's predicament of not being able to find their missing queen, and Pegasus designed a card of Madolche Tiaramisu and sent it to Miu, reawakening Tiaramisu and becoming one of the first ever XYZ cards. Miu went to a general high school, but decided to attend Duel Academia thinking that she might be able to learn more about the monsters that she could see.

The Secret of Red
In the pilot, Miu is introduced as a sleepy spirit seer who rooms with Saki Yamaguchi. She seems unperturbed by the revelation that Osiris Red is for students with powers.

Red Days
Miu was enrolled at Duel Academia in Osiris Red, rooming with Saki Yamaguchi. Although initially planning on just coasting through her school life, upon learning about the truth of Osiris, she started to become closer to the others in the dorm and making real friends. She participated in the mid-term tag duel with Saki, helping them to win with her XYZ Madolche Tiaramisu.

Miu got involved with the other students in their plan to search for Saya's missing sister, Hinata, planning to use her dimension walking powers to move to wherever Hinata was once they determined her location. After their investigation led her and several others to be kidnapped to another dimension, Miu used her powers to get back to the physical realm, where she enlisted Judai's help in finding and rescuing the kidnapped students.

Duel Academia Year 2
Miu had no interest in transferring to another dorm when the option was presented to her, deciding to remain in Osiris without any reservations. Miu later got involved in a situation with new student Keiko, who took a dislike to Miu and started bullying her. Miu went to Saki for help, and then challenged Keiko to a Shadow Game, which she won and got Keiko to apologize to her and the others she'd upset with her schemes.

Miu assisted the other students and teachers in investigating the missing students kidnapped by Armityle, but was unable to use her dimension walking powers to sense the bubble dimensions or move in or out of them. She was in the middle of investigation with another group when Saki disappeared and Armityle was eventually dealt with, and rejoined her friends at the nurse's office once they were freed.

Saki Yamaguchi
Saki is Miu's roommate and best friend. Before Saki, Miu hadn't had any friends outside of her duel spirits, and didn't really intend on making any. Saki's determination and kind nature, however, won Miu over, and she quietly began to glom onto her and rely on her. Saki is the only person that Miu trusts to completely have her back.

Minato Fujita
Minato is one of Miu's friends and classmates. Though not as close to them as she is to Saki, she likes Minato for saying what they think and not sugarcoating their feelings.

Taro Inugawa
Taro is one of Miu's friends and classmates. She tends to find him a bit overwhelming and sometimes even annoying, but his loyalty has truly struck her, and she consider him a very close friend.

Nina Orlando
Nina is one of Miu's friends and classmates. Miu finds Nina's energy to be exhausting, but will allow herself to be dragged along on adventures so long as she's allowed to nap afterward.

Mewfeuille
Madolche Mewfeuille is Miu's spirit partner and ka spirit. She thinks of Mewfeuille as her nap buddy, and spends almost one hundred percent of her time with it. Both are nap fiends who love to cuddle each other.

Keiko Ueda
Keiko is Miu's underclassman, who initially disliked Miu and decided to target her for mean bullying and pranks. Miu dislikes Keiko for her tendency to lie and pretend to be someone she's not in order to get attention and to get people to like her. Keiko is one of the few people to actually be able to ruffle Miu's normally unperturbed personality. After their Shadow Game, Miu is more tolerant of Keiko, and thinks of her as someone to look out for here and there, though she still disapproves of Keiko's methods of friendship.
