Yukie Mayuzumi

As for her backstory, Yukie Mayuzumi (黛 由紀江) is one of the main heroines in Maji De Watashi Ni Koi Shinasai! anime and manga. She is a newcomer to the Kazama Family who has the ambition to make one hundred friends, the daughter of Taisei Mayuzumi and one of the love interests to Yamato Naoe in Majikoi! and Majikoi! S.

Yukie is the recent and latest addition to the Four Devas, a group made of the strongest fighters in the world. This is a fact that is relatively unknown to the public however, due to Yukie's withdrawn personality.

Yukie is a fighter of most special interest to Momoyo Kawakami due to her strength and potential with Momoyo watching for her development with a desire to face Yukie in a decent fight.

Yukie represents Respect (礼, Rei), one of the seven virtues of martial arts. Yukie was born as the eldest of two daughters of the Sword Saint Taisei Mayuzumi and his wife in the Ishikawa prefecture in the Hokuriku region. Being the elder, Yukie began training in the Mayuzumi style of swordsmanship since she was young in order to succeed her father. Her father was able to get permission for him to carry a real katana, and he passed this honor onto his daughter. Along with her sword training, Yukie was also taught proper home etiquette and manners by her mother.

Being trained constantly in sword fighting and martial arts from a young age, Yukie failed to develop any real social skills and was unable to make friends with other kids. She has since become a really shy and awkward girl, and she unintentionally scares off many people with her weird behavior and her scary smiles.

As a result of her solitude, her father made her a small black horse cell phone strap who she named Matsukaze. Developing ventriloquist skills, Yukie was able to give Matsukaze a voice and even though it's an object, Matsukaze became both Yukie's first friend and a device to speak out her inner feelings.

While having a great relationship with Sayaka Mayuzumi (Yukie's younger sister), Yukie would become in awe of Sayaka due to her ability to make friends so easily. However, this was due to Yukie being the successor to the Mayuzumi style, making her bound to stricter training than her sister.

Eventually, Yukie's strength would gain her father’s recognition, and his acceptance that she had surpassed him. Not long after, Yukie was organized to duel with a member of the Big Four, Takae Tachibana. Defeating her, Yukie inherited the title of one of the Four Devas, but it's not common knowledge that Yukie is the one who defeated Takae. Despite this accomplishment, Yukie's true desire was to create a real friend and social skills. However, Yukie had odd perks when it came to interacting with other, such as creating a scary awkward face and running away from people, apologizing for disturbing them. Deciding that it was time to expand her horizons, she requested to be transferred to Kawakami Academy for her senior years of school. Yukie’s request would be accepted, and she would take her sword and Matsukaze with her, along with the ambition to create a hundred friends.

Appearance wise, Yukie is a fairly tall and soft pale-skinned girl with thigh-length deep forest-green hair that is tied in two low pigtails by two white ribbons with square bangs, dark blue eyes, a voluptuous figure, she keeps herself well kept that gives off a yamato nadeshiko aura and it has been commentated that she has a great butt (by Yamato Naoe and Momoyo Kawakami) that even most of the merchandises involving her emphasizes it. Personality wise, Yukie is an overly kind and humble, but excessively self-conscious and non-assertive girl. Due to her shy and timid personality, she has a hard time speaking out loud and tends to say words beneath her breath, making it hard for others to hear. Due to her self-conscience and "I'm at fault" personality, she always feels like she has done something wrong when things get awkward around her. Yukie consults with Matsukaze about these issues and "trains" to ensure that they don't happen again. Despite her sword being one of the reason people feel intimidated of her and makes them stay away, Yukie refuses to part from it, feeling that her sword is the house of her soul. After becoming a member of the Kazama Family she starts to slowly leave her sword behind when in social situations, but always has it within close reach. Yukie is extremely humble with her hardly ever acknowledging her achievements. Such an occasion is after the Kawakami War when the girls of the Kazama Family praised her for fighting Momoyo Kawakami, with Yukie saying that it was nothing special. Even though she is young and innocent, Yukie is a lot more perverted than she seems, researching erotic material and learning about sexual positions, it was hinted that she masturbates daily in the game series. Matsukaze however, takes the blame for it on Yukie's behalf. She also is a bit of a masochist, wanting to embraced fiercely by Yamato Naoe in her own route. Even though she doesn't like to fight despite being one of the Big Four, she will face anyone who hurts those she cares about with great ferocity. Whenever Yukie takes out her sword, people instantly notice the change in her personality, along with the fierce look in her eyes. Yukie also stands with confidence and discipline and shows no awkwardness of fear in her speech. Yukie has great respect for her parents, and notes that despite Taisei Mayuzumi's strict training, that he was 'tough but kind'. Yukie both admires and envies her younger sister Sayaka Mayuzumi for her social skills and for always hanging out with friends while Yukie struggled to make any. Upon joining the Kazama Family, Yukie gradually began to show small changes as time went on, with her being more outspoken, assertive, calm and happy while within their presence. The members of the Kazama Family feel that Yukie is someone that needs to be raised up carefully due to Yukie's lack of social skills. Yukie also acknowledges Kazama Shouichi as leader of the Kazama Family, even though she originally felt that someone like Momoyo would of probably of been the first choice. In the beginning she has a slight attraction to Gakuto Shimazu as he reminds her of her father. Gakuto however, rejects her because he was interested in older women, despite Yukie not having any interest in him romantically. Gakuto however continues to look out for Yukie and tends to give her company when the Kazama Family splits into small groups for occasions. However she has an affinity for Yamato Naoe, showing feelings for him in both the manga and anime. In Margit Eberbach's and Lin Chong's route she is shown masturbating while either thinking of him or Yamato having sex in the next room. She even is willing to engage is sexually activity with Yamato in Sayaka's route. In Azumi Oshitari's route Yamato notes that she calls him often and has gotten attached to him. Yukie can be very protective of those she cares about. During the Agave Route when the drug Utopia spreads around the school so close to her friend Iyo she becomes enraged. Kosugi Musashi comments that her aura took the appearance of an Asura. During Sayaka's route when Sayaka is kidnapped she gets very angry and attacks everyone insight at the Ayanokouji household. Yukie also becomes protective of Yamato during her own route releasing hostility unconsciously when Margit threatens Yamato. In her after S route, she becomes a bit more outgoing and cheerful as a result of falling in love with Yamato. She also doesn't talk to her strap anymore but she can still do a Matzukaze imitation. Her natural smile also comes out more often making people feel less threatened when around her. This also made her really popular with guys as seen during the end of her after S route.
