Episode 20

Kazumi Yukihira (行平 一己 Yukihira Kazumi) is the High School Principal of Alice Academy. He is the elder brother of Izumi Yukihira and the uncle of Mikan Sakura.

Appearance and Personality

From the effects of his Longevity Alice, Kazu forever keeps an appearance around his 20's. His hairstyle is similar to what Yuki had with his bangs covering his eyes. He has fair skin, light blonde hair and blue eyes like Yuki. He is usually seen in his blue uniform (brown in anime). He is taller than Izumi, and it is revealed that he is the tallest man among the adult characters.

His personality, however, is contrast to Izumi. While Izumi has a cheerful, social, and kind personality, he was more serious than his younger brother. However, he can be very intimidating just like Izumi. This usually when he beats Izumi up, together with Jinno whenever Izumi commits any mistakes or wrongdoing.

Although he was strict and was always bullying Izumi (due to his stupid mistakes), according to Noda during the Time Travel Arc, he still loved and doted Izumi a lot, as Izumi said that he was a person he always looked up to. It is showed that in chapter 116, he was shocked to see Izumi's dead body, and that he touched Izumi's face and closed his eyes with tears that are barely seen, losing a brother that he loved very much. That affection was later passed onto Izumi's daughter, and the HSP's niece, Mikan. He teases her and comments that she inherited her father's intelligence of stupidity, but he clearly loves her and wants to protect her, and even asks her to call him "Uncle" and not be formal with him because he had been formal with Izumi before he died.



Kazu found out that he and Izumi were brother's, because they both had the same last name. While exchanging letters he figured out that his brother, Izumi had an alice when looking at a picture of him. When Izumi arrives, instead of greeting him properly, he hits his head, much to everyone's surprise. He later explained to Izumi about the students and the academy. He also mentioned that he know less about family and sibling, thus having a family is something impossible to him, as he spend his entire childhood in the academy and also did not have any contacts to the outside world.

Throughout the story he listens his brother's growing feelings for Yuka Azumi and hits him whenever he did something wrong and after confesses his feelings to her. When he dies Kazu remembers a conversation of him and Izumi with him saying everything would be easier if he died, which makes him regretful. He was the one who told Yuka about the death of Izumi, and making the annoucement of his death during the assembly.

He is later in his office with Jinno, Shiki Masachika, and Yuka asking her if she can live outside, which she replies, Yes. Kazu then notices a glow coming from Yuka's stomach realizing that Yuka is pregnant with Izumi's child and that child has an alice. He later contacts Kaoru to tell her that Yuka escaped and that she is pregnant.

He was first appeared as one of the three principals of each divisions: Elementary, Middle and High School Division. Mikan was not able to meet them during the opening ceremony, and was shocked to see him and the other two principals during the closing ceremony and prize-giving. According to Tsubasa, many students were surprise to see them that time. He also mentioned that time that not all of them known the details of the three pincipal themself, except that nothing good would happen if any of them caught the attentions of the principals.

Sports Festival

He secretly instructed Goshima Hijiri to help Mikan from being captured by Fuukitai. During the Cheerleader Competition, he was about to catch Mikan from falling down. Later on during Kibasen, he was shocked when he saw Mikan carrying the alice stones along with the two principals, suspected her to have the Stealing Alice.

High School Division Arc

He helps Mikan escape the elementary school principal and takes her to his office and introduces himself as her uncle from her father's side in chapter 100 . Kazumi tells Mikan about her parents and lets Mikan decide what she wants to do with the help of Noda's alice of time travel. He and the others are attacked by the ESP at the end of Chapter 123 leaving his office a mess and empty when Mikan and the others return from time traveling. In Chapter 131, Sakurano revealed to Mikan that her uncle-Principal Yukihira was able to escape from the ESP's attack, since Sakurano and the others helped him and in the care of someone. Kazumi is currentely in the care of Shiki and appears injured. In Chapter 132, it was show that Shiki went to Hanahime-Den together with unconscious HSP, shocking Kakitsubata and the other Hanahime. In early Chapter 133, the HSP was seen unconscious and lying on the futon somewhere in Hanahime-den, while the Hanahime princesses and Kakitsubata accompanying Shiki, who was sit besides Hii-sama.

Final Arc

In Chapter 140, he was seen holding an umbrella for Mikan as he walked with her during Yuka Azumi's funeral. He was trying to comfort her. He was last seen in the chapter, walking away with Shiki, Jinno, Mikan and the rest of the staff.

In Chapter 141, he was one of the few people who were able to have contact with Mikan along with Bear and Shiki. The HSP insists Mikan not to be formal with him and to call him "Uncle". The HSP tends to her studies and is amused that she inherited her father's brains and says that they work on Yuka's ability to study when it comes to brains. He also tells Mikan about her parents and how her friends are doing.

In the latest chapters (Chapter 141 and 142), he was with Jinno and the others at the hospital where Noda was hospitalized, after he returned from the time space's journey. He explained to everyone about his actions with the ESP's spy-Hijiri Goshima and constructed Sakurano and Subaru to watch over him by placing them into the student council. He feared that one day the ESP will take his move against them. He also realized that the ESP finally started his movement again by requesting Shiki to return back his Alice stones, which were stolen by Yuka and Shiki while they were still considered as terrorists.

During the Christmas Party, he sat with Shiki and Hii-sama. He stared at Shiki with an unusual look along with the others when Shiki mentioned that Mikan was to watch the party from her room. This situation had caused him to give suggestions for Shiki to take some fresh air, and called him 'Young Master'.

At Reo's concert, it is revealed that he and Shiki have teamed up with Narumi to assassinate the ESP and get him to confess what he has been doing to the students. The HSP takes over the control room and broadcasts the event all over Japan while Narumi grabs the ESP and reveals all the evil things the ESP has done.

In the ensuing battle, the HSP watches the battle from his office. When Mikan escapes from her room, the HSP is worried. When she subconciously uses her Alice to stop Natsume's flames, the HSP and Shiki feel an abnormal amount of power from Mikan and realize that she has the third Alice shape form, which the Alice is powerful but short-lived. He and Shiki go to check on Mikan once Luna stops the ESP and find Mikan badly injured and Natsume having a near death experience. He tells Mikan to insert Natsume's Alice stone into him, but when she fails to do so, the HSP tells her that she had lost her Alice. He tells her to absorb her own Alice to give her the ability to insert the stone, but it will mean she can't stay in the academy because she will no longer have an Alice. Mikan decides to do it anyway because she can't bear to lose Natsume forever.

When her plan fails and it costs Mikan her Alice, the HSP and academy council decide to not only expell Mikan but erase her memories to protect her from the academy's enemies. Mikan is shocked and pleads with her uncle to prevent it, but he knows it is to protect her. He later takes part in the memory lesson, where everyone tells their favorite memory of Mikan. A couple of days later, he watches Mikan leave the academy, and calls her his precious niece.

After Mikan's departure, the HSP and Shiki suspected that the academy's enemies suspected Mikan's identity and created a barrier to protect her. When she is found, however, he decides to bring her back to the academy. He talks with her grandfather and asks for consent, which is given. He also supports Mikan's decision to go find Hotaru.


Kazumi's Alices are both quite rare. His primary Alice is the Longevity Alice (不老長寿のアリス Furōchōju no Alice) and the Alice Holder Detection Alice. He can live forever with his alice of longevity. His second alice is the Detection Alice that allows him to know what Alice or Alices a person has by meeting them in person or looking at them in a picture. It is shown in the latest chapters that he can also see if a unborn child has an alice by looking at the mother's stomach and see a glow.

Although his Alice is rare to found, however his Alice has a weakness; he could not be able to attack or protect himself from danger. This similarity is shared with Hijiri Goshima, whose Alice isn't very advantageous during dangerous situations.

Izumi was Kazumi's younger brother and his only family in the academy. He accidentally saw his photo and realized that he was an Alice, thus making them to know each other through writing letters. Despite their age gap of 18 years, Kazu still doted on and loved Izumi a lot. When he died, Kazu felt guilty as he remembered his earlier conversation with Izumi. He later discovered Yuka was carrying Izumi's child, thus shocking him more than he thought.

Mikan Sakura

Main article: Mikan Sakura

Mikan Sakura is the daughter of Yuka Azumi and Izumi Yukihira, thus making her as Kazu's only niece and living relative. He was worried about her and watching her from the shadow (according to Goshima in Chapter 81). He is willing to help Yuka take Mikan out of the academy as her Stealing Alice could endanger her, thus fearing history will repeat itself. He revealed himself to her as her paternal uncle (uncle from her father's side) and also the history of her parents. He becomes one of her guardians and helps her study, and tells her how her friends are doing. Because she reminds him of his late brother, he has great affection for her and will protect her from the ESP.


Main article: Jinno

Jinno is the Math teacher and the head supervisor of the Elementary School Division. He was serving under the circumstance of Kazu Yukihira, even before the current story took place.

In Chapter 98, it was revealed that he actually served the role of observing the ESP's movement, as he told Narumi that he and the others believed in the same way the HSP felt and moving in the shadow to stop the ESP's true plan.


Main article: Himemiya

She is the Middle School Division Principal and blood relative of Shiki Masachika. She accepted the HSP's request on the behalf of his brother Izumi, to look after Yuka Azumi. In Chapter 126, she seemed to be in the same line as Kazu, as she stated that many innocent people had died including Kaoru Igarashi and Izumi Yukihira, and she cannot bear it anymore. Hii-sama, alongside with Shiki also helped the HSP and the others escaped from the ESP's surprise attack by casting her barrier alice on them.

Masachika Shiki

Main article: Masachika Shiki

Hī-sama is Shiki's distant relative, which is probably why she allows him in her presence and shows no disgust towards him like she does to other males. He inherited her powerful Barrier Alice and was the long waited successor to be the protecter of the school. Although Shiki always felt that this future position was not a path he chosen, he, with a heavy heart, accepted it long ago.

He shared the same characteristic of HSP and even are 'good partner' in teasing Mikan during chapter 141.
