"There is nothing I cannot cut..."
Yukie Mayuzumi
Yukie Mayuzumi (由紀江 黛) is one of the main heroines in Maji De Watashi Ni Koi Shinasai!. She is a newcomer to the Kazama Family who has the ambition to make one hundred friends. She is one of the love interests to Yamato Naoe in Majikoi! and Majikoi! S, and a main character in both the anime and the manga

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 This is a fact that is relatively unknown to the public however, due to Yukie's withdrawn personality.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.


Yukie is one of The Big Four or 4 Devas, getting the title by defeating Takae Tachibana, stripping her of the title. The complete name of her title is Yukie Mayuzumi of the West.

Since she only defeated Takae who was the weakest among them, she has become the weakest member of the Four Devas. However, she has proven capable of facing Gyoubu Shakadou, Margit Eberbach and Yoshitsune Minamoto one on one. Also, Tsubame Matsunaga has mentioned that despite her mastery of weapons, Yukie's swordsmanship is greater than hers.


In the year 2009, Yukie moved to Kawakami City to begin her senior years of school at Kawakami Academy and she took up residence in the Shimazu dorm after joining the Kazama Family.

Yukie's first interaction with the Kazama Family came from Yamato Naoe as she ran into him as she wanted to arrive early to school. She dropped Matsukaze as a result, and Yamato handed him back to Yukie. Yamato then spoke in his radio in code and had someone inspect her because she was carrying a sword. A little while later, Yukie apologized for the incident, and the guard assured Yamato that Yukie had government permission to carry her sword. During the incident, Yamato caught a glimpse of Yukie's green panties.

Yukie would continually try to become friends with the residents of the Shimazu dorm, even offering to make food for them and offering candy at one point. However, Yukie ended up getting scared and apologized for interrupting them. However, Yamato and Shouichi Kazama invited Yukie to have lunch with them which was a stepping stone for her.


Later, when the Kazama Family was celebrating the addition of Christiane Friedrich to the Kazama family, Yukie took the opportunity to request becoming a member of the group of friends, offering her services. The Kazama Family started to silently communicate with each other on what to do with her request. However, Shouichi Kazama said that friends were meant to be on an equal level and that due to Yukie's grovelling he could not allow her to join, saying that Yukie had to ask to become their friends since it looked like fun. Yukie took the opportunity immediately and while Shouichi was amused, he immediately refused, causing Yukie to faint. Shouichi simply chuckled that he was joking and allowed Yukie to become the ninth member of the Kazama Family, stating that he found Yukie to be interesting. The Kazama Family then gave her the nickname Mayucchi, although Momoyo Kawakami said that she would call her Mayumayu instead. Momoyo then started to play around with Yukie, until she noted that Yukie was strong and immediately started throwing punches at her. Yukie was able to dodge them all, surprising the other members of the Kazama Family. Momoyo then revealed that she knew Yukie was the daughter of Taisei Mayuzumi and that Yukie had more strength to her fighting ability than she was showing. Momoyo instantly became interested in the thought of fighting Yukie, but felt that Yukie needed to become serious in order to show her full potential.

When she and Chris were introduced to the Kazama Family hideout, Yukie was immediately excited about having a secret hideout, saying that she always wanted one when she was a child, but lacked the friends to do so. Yamato would find her and Gakuto Shimazu outside with Gakuto showing Yukie around the building and telling her to be careful to not lean over the edge at the top of the building. Back inside the building, as Chris was being shown around, Chris started to question the purpose of having a hideout in an abandoned building. Seeing no point in the hideout, Chris said that she felt that the building should be demolished. Miyako instantly insulted and tried to attack Chris but was stopped by both Yamato and Momoyo. Yamato then tried to talk sense into Chris, who was oblivious as to how she insulted them. Yukie then tried to calm things down, begging everyone to try and get along, but Yamato instead gave her a warning, saying she was too subservient and it just complicate things if she kept grovelling to others instead of treating them as equals like real friends should. Both she and Chris apologized and the situation soon calmed down when Chris acknowledged that people value different things. Soon the atmosphere returned to normal, and Chris and Yukie both said to each other that they would try to do better after getting in trouble. This started a close friendship between the two.

Upon Yukie seeing an old picture of the Kazama Family in front of the century plant, they were then told the story about the Kazama family promise to watch the flower bloom again. They were then invited to witness the next blooming of the flower decades in the future to which they both agreed.

As a month passed, both Yukie and Chris would be accepted into the Kazama family completely. While happy that she now had friends, Yukie would try to find more friends in the same year as her and would continue her goal of making 100 friends. She eventually makes with Iyo Oowada, a classmate of her.


Yukie has blue eyes, and long deep forest green hair that goes past her waist. She uses two white ribbons to tie her hair with. She has soft, pale skin. She is fairly tall and has a voluptuous figure. She keeps herself well kept giving off a yamato nadeshiko aura. It has been commentated by Yamato and Momoyo that she has a greatt butt, even most of the merchandises involving her emphasizes it.



Yukie is an overly kind and humble but excessively self-conscious and non-assertive girl.

Due to her shy and timid personality, Yukie 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 in her own route.

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 her father'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.

After S route Personality

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.


In routes other than her own it's stated she is happily living near her family in the Hokuriku region. Despite her being of marriageable age and her father wanting her to get married, she shows no sign of getting a boyfriend or lover.

Powers and Abilities

Being a member of the Four Devas and the successor of Mayuzumi Style of swordsmanship, Yukie Mayuzumi is one of the most powerful characters in Majikoi!, possible being the strongest swordswoman so far. Yukie has shown numberous times fought the most skilled fighters such as Azumi Oshitari, Gyoubu Shakadou, Yoshitsune Minamoto and Momoyo Kawakami. So far that during the Kawakami War in the manga, only she could fight Momoyo in an extended period of times and make her struggle against Yukie. Momoyo feels that with constant training, Yukie could even surpass her some day and make a great rival.

Her father Taisei Mayuzumi, stated that Yukie has surpassed him.

Master Swordswoman: Yukie’s greatest skill lies in her swordsmanship as her skills with the sword has been described as elegant and beautiful by some of the most hardened fighter such as Azumi Oshitari. With her mastery of swordsmanship, she was able to defeat Takae Tachibana, the weakest member of the Big Four reowned for unmatched speed and claimed her title before the events of original Majikoi!. In Koyuki Sakakibara's route, Yukie admitted that Yoshitsune was faster than her, but because of her determination she was able to grasp the right moment to strike and defeat her in the final sword clash. During her battle against Xiang Yu in Seiso Hazakura's route, Yu complimented her sword skills and asked her to join her future army in conquering the world only for Yukie to turn her down. In Seiso's route during the mock battles Yukie has many times giving Xiang Yu the hard times as she counters her attack easily and brings the victory to her team.

Great Strength: Despite her fragile demeanor and mild looking, Yukie possesses exceptional prowess in hand-to-hand combat, as shown in her own route in the original Majikoi! where she defeats Kosugi Musashi who was regarded as the strongest in first grade after she spreaded bad rumors about Iyo, in one blow. Tesshin Kawakami states it will take one month for Kosugi to recover while her bloods still stained on Yukie's fist.

Godlike Speed: Yukie's speed with the sword is also on par with Cookie in his second form, whose own sword speed is described as 'godlike'. Yukie's speed is so fast that she is able to slash at several directions multiple times in almost an instant. The only known person who has given her a hard time during a 1 vs 1 sword match is Yoshitsune Minamoto. Yukie also has great reflexes and is able to dodge attacks from both Cookie and Momoyo, both of whom have incredible speed in their own right.

Enhanced Stamina: Yukie has a lot of stamina and energy, giving her the edge against most opponents. However, while still a growing fighter, she is only able to fight against Momoyo Kawakami for a certain period of time, even with the aid of Ageha Kuki, before becoming overwhelmed.

Keen Intellect: In addition to her swordsmanship skills, Yukie is also highly intelligent, to the point that she is able to join Class 1-S, the elite freshmen of Kawakami Academy. However, Yukie rejected the offer in order not to start from scratch in getting to know people in order to make friends with them. She is also good in speaking English.

Exceptional Cook: As well as being a skilled fighter, Yukie also has great house etiquette. She is a very tidy person and has great cooking skills that she uses to assist Reiko Shimazu to make breakfast at the Shimazu dorm. She also can create specialty dishes such as the Mayuzumi drink (hot coarse tea with dried plum, soy sauce and ginger extract) and Mayuzumi dangos (makes with soy sauce and dried seaweed, giving it a sweet and soft taste).

Master Ki Perceptor: It is also noted that Yukie's ki sense already surpassed many others master-class fighters. For instance during Kazuko Kawakami's route in Majikoi! visual novel she could do a ki search (they were looking for Kazuko since she disappeared) within a 5 km-radius which already surpasses Momoyo's ki sense and also Momoyo herself was really impressed by her feat. Also on multiply occasions during the Majikoi! S novels she could detect the ki of multiply Kuki butlers while they were hiding their ki. Claudio Nero (Kuki butler number 3) commented that he is really impressed by her skill to detect ki since they themselves were skilled in hiding it.


Most likely her weakest ability lies in her social skills. Despite trying to be nice and smile to others, her face tends to stiffen and shows a scary grinning and angry face. Having little to no confidence, Yukie tends to apologize immediately when talking to others and ends up running from them.


Matsukaze: a black horse cell phone strap which belongs to Yukie. He was made by her father due to Yukie's shy personality, just for her.

Despite being an object, Matsukaze became Yukie’s first friend.

Matsukaze claimed that he is a spirit that has possessed the cell phone strap but in reality it's just Yukie performing ventriloquism. Yukie says that since she had no friends, she ended up talking to the object and that one day, it talked back to her, leading to the birth of Matsukaze.

Shouichi says Matsukaze is another part of Yukie and he finds it entertaining to watch the two talks to one another.

Matsukaze seems to be Yukie's inner voice, with him saying things that are normally, if not completely, out of Yukie's character.

During Yukie's route Matsukaze decides it's time to say farewell. Finding the strength from her new found friends and lover, Yukie manages to once again accept Matsukaze as a part of her and finally takes Matsukaze back into her own psyche.

Tachi: Yukie carries a long Japanese sword which passed onto her by her father Taisei as a tradition of the Mayuzumi Family.
