Manga Volume 14, Chapter 77

Luna Koizumi (Koizumi Runa 小泉 月?) is only shown in the manga not in the anime. She is the former friend of Yuka Azumi and now holds complete hatred towards her and her daughter, Mikan.

Luna causes problems between Mikan Sakura and Natsume Hyūga by taking on a twelve year-old form. She is in love with the Elementary School Principal and acts as his spy on Mikan and Yuka.


Luna has short strawberry-blonde hair that almost reaches her shoulders and cold blue eyes. She currently takes the appearance of an eleven year-old girl, but is truly a full-grown woman. Under her lip is a beauty mark. She also has thick lips.


During her first appearance, Luna appeared innocent and timid, and a bit of an introvert who is to shy to interact with people. However she can be persuasive and critical, such as demanding Natsume join her team for the Sports Festival and criticizing him and Mikan for the flaws she perceives then to be making. To those she feels deserving, she is unquestionably loyal and polite but to those who she feels are undeserving, she is downright cruel.

She demonstrates the characteristics of a violent psychopath to the point she wanted to simply kill Mikan out of spite towards Yuka despite the Elementary School Principal’s order to leave her to him. Although intelligent and calculated, Luna is mentally unstable. This is rooted from the turmoil she endured all her life; abandoned by her parents, bullied by her classmates, and believing Yuka had betrayed her by stealing her Alice. When she suspected Yuka was trying to get the ESP’s attention, Luna, who had fallen in love with the ESP, who treated her with kindness rather than disdain, Luna sought out to make Yuka’s life as unhappy as possible. Although she has been serving the ESP the longest, Luna didn’t know what his true feelings for her were but she undoubtedly trusted him and the ESP never considered the possibility she would one day oppose him. Her Soul-Sucking Alice and unwavering loyalty made her so valuable to the ESP that he personally made her his favorite assassin who never failed to complete her assignments.

Luna’s deep hatred towards Yuka extends towards those dear to her, including her daughter and friends. Referring Yuka and Kaoru Hyūga as useless and expressing exhilaration at Izumi’s death, Luna takes joy in inflicting pain on others. By her own admission, she despises Mikan and Natsume for their close resemblance to their mothers, as well as that Mikan became the object of the ESP’s attention, making her jealous that Mikan was more important than her. Luna never forgave Yuka for rendering the ESP as a child and vowed to exact revenge. Even when her presence in the Academy was enough to force Yuka out of hiding, Luna extended her desire for vengeance onto Mikan. Her plans are ultimately setback when she witnesses Yuka’s death and deduces the ESP ordered Goshima to carry it out as a last resort to stop Yuka from taking Mikan out of the Academy. Luna is overcome with shock and sadness as Yuka passes away, especially as Yuka’s last words were an apology to Luna. As a result, Luna began to question her loyalty to the ESP and her hatred began to diminish. Mikan tries to explain the missteps Luna has been making but it isn’t until Mikan helps Luna realize how she sacrificed everything precious to her to appease the ESP for the affection she felt she had been denied all her life whereas it was Yuka who truly gave her that affection. Luna finally accepts her mistakes and turns against the ESP by personally ending his reign of horror at the cost of his life. Although she admits she now felt disgust at him for the extent of his crimes, she professes her love for him has always been genuine and will continue after his death.

Luna then becomes guilt-ridden and accepts she will be imprisoned for the rest of her life. She feels indebted to Mikan for helping her realize her mistakes and giving her confidence in herself. She makes her first step in atonement by apologizing to Mikan for everything and assuring the young girl she had reconciled with Yuka. Luna also takes on the responsibility of tending to the ESP’s body as he quickly ages into an infant.



Like many Alice children, Luna was abandoned at the academy by her parents. As a child, she was feared due to her Soul Sucking Alice and was put into the Dangerous Ability Class. Yuka had always been her classmate, and Luna admired her. One day, Luna approached Yuka and asked her if they could be best friends, which Yuka accepted, and since then, Luna followed her everywhere. Luna, however, fell in love with the ESP after he started to treat her better than the rest of the Dangerous Ability students. By the time they reached middle school, she started to dislike Yuka when rumors of the ESP and Yuka being in a relationship spreaded, and when Yuka accidentally stole her alice. Yuka used her alice because Luna has become more angry and had been using her Alice on other students to make them her friends. Yuka did this thinking that this would save her. When Yukihira comes to the middle school section, Luna smiles sweetly and greets him and he sees bite marks on students next to her. Yukihira then has a talk with Luna. Yukihira tells her how she was friends with Yuka and that Yuka still cares for her and that she still cares for Yuka. This leaves her confused and asks Yukihira what he means, but he leaves. Later on, Luna appears in front of Yuka and tells her that because of her, everyone around her has suffered. Shiki then stops her before she says anymore, but Luna's words hurt Yuka greatly. She is greatly shocked by Yukihira's death. In the latest chapter, Luna came into the room where Yuka and the ESP are and Yuka tearfully leaves and said goodbye to her. Luna is with Persona while the ESP is in the hospital noticing him shrink. Luna then decides to take the ESP's idea of capturing Yuka, since she and Yuka are no longer friends, and chooses to stay by his side.

The New Student

12 years later, Luna appears as a new student in Mikan's class; she was ordered by the ESP to watch Mikan and confirm she has the Stealing Alice. She starts coughing up blood, hinting that she suffers from the Life-Draining Alice form. She sees Mikan and Natsume, and seems to realize who they are. She wants to sit next to Natsume, but Natsume refuses, telling Mikan to stay. Luna then coughs up blood and Natsume has no choice but to let her sit next to him. She meets Mikan and tries to touch her on the face when Mikan tells what her Alice is, but is stopped by Natsume and Hotaru. Luna takes advantage of the moment and holds hands with Natsume and asks him to sit with her to make Mikan jealous. Natsume then allows her to sit by him, sensing something odd about Luna.  She then tells Natsume to join the White Team (the team Luna is on) for the Sports Festival, prompting Mikan to demand him to choose her or Luna. Natsume goes with Luna, knowing she is trouble to Mikan.  Luna then becomes the new partner to Natsume, much to Mikan's personal horror.  While walking with Natsume, he insults her saying "Let go of me, you damn leetch. You're pissing me off." causing Luna to smack him and tell him "'You're pissing me off' is my line." She then remarks how his eyes are similar to his mother and that she forgives him for his disrespect.  While the incident of flinging objects, Luna traps Mikan in the gym basement, attempting to strangle her, and says that she knows about Mikan's parents. She then says she can't wait to see Mikan suffer, but if she acts a good girl, Luna will tell her of her birth secrets. When they are found, Luna says she was bullied by Mikan, which gets her taken by the Student Police.

Sports Festival

Luna spends most of the festival close to Natsume to make Mikan jealous and uses her Alice on other students to make Mikan appear to be a troublemaker. She does this by making it seem that it was Mikan's fault that she fell during the cheerleading competition. When she was the one who controlled the person with telekinesis with her alice.  When Natsume confronts her on the incident, she callously says that he and Mikan are on "thin ice". After Mikan is brought to the finish line during the borrowing race by a masked Natsume and Mikan suspects that the person could be Natsume, Luna crushes her hopes by telling her Natsume was with her. After this Hotaru, who is suspicious of her tries to befriend Luna, but Luna uses this opportunity to try to use her alice to control Hotaru, but is stopped by Ruka Nogi. In the horseback race challenge, Luna uses the same trick to have a teammate of Mikan attack her. Mikan unknowingly uses her Stealing Alice to remove Luna's Alice from the teammate. Luna is furious that Mikan did that and Mikan is mad that Luna is causing the chaos on purpose. Mikan attacks Luna, causing the two to use their Alices and past out.

Escape Arc

Mikan steal luna

Mikan steals Luna's alice.

Luna controls many students and has them say cruel things about Mikan about how she is the cause of the academy's misfortunes. After a student falsely accuses her of stealing his Alice, Mikan is forced away to the Elementary Principal's office with Luna following her. Luna brawls with Mikan to get Mikan to use her Stealing Alice. During the fight, Mikan accidentally stole her Alice. While it pleased the ESP, Luna is furious that Mikan stole her Alice, calling her a thief and saying how alike she and Yuka are. She was about to go after Mikan until her hair got caught on fire from Natsume. As Mikan and Natsume escape, she angrily shouted that Mikan still has her Alice and calls her a thief. While Natsume and Mikan were escaping she was seen fighting with Permy.

Time Travel Arc

Luna adult

Luna's adult form.

She later is seen by Mikan's captured friends with Subaru Imai who is under control of her Soul Sucking Alice which makes him an ally. Luna also took control over the students who were unwillful about capturing Mikan for the ESP. She's seen with Persona and the Dangerous Ability students in her adult form. Her child form is found out to be caused by Gulliver Candy. A Fuukitai member questions her about her body being damaged from using the Gulliver Candy, but she responds that she is alright. She announces she is saving energy to end the tag game between her and Yuka.

Luna ignores the warnings of the Fuukitai about her body and even though she is very weak, she pushed herself to go to the Keyhole where Yuka is. Luna doesn't care about herself being hurt, but a conservation with the Fuukitai reveals that if she collapses something (most likely injury or even death) will happen to the victims affected by her Alice.

Luna interrupts Yuka and Mikan's reunion armed with a group of Fuukitai. Her body is in an even worse state this time. Yuka questions why Luna is hurting herself for the sake of the ESP, but Luna stops her yelling, "SHUT UP! I don't want to hear from someone like you, who always gained love and concern... without having do anything. Never say things like you understand how it feels." She then orders the Fuukitai to commence attacking and follows Yuka and Mikan to the Keyhole. While fighting with Mikan and her peers, Yuka managed to open the Keyhole, but it made a huge explosion, causing Yuka to be hurt severely. She apologized to Luna, much to Luna's surprise. The Fuukitai, being controlled by Luna, treated Yuka. The Fuukitai then mentioned to everybody that Yuka's breathing had stopped. Seconds after that, Yuka passed away, leaving Luna in a state of shock. She is further shocked when the ESP appears and she realizes that he had ordered Yuka to be killed. She seemed like she couldn't understand that he would be capable of such an act.

Final Arc

At Yuka's funeral, she remembers Yuka's dying words (she apologizes to Luna or forgives her), and Luna expresses an emotional forgiveness for Yuka for her past deeds. Luna falls into a depression and her mind is haunted by Yuka's last words. She begins drinking excessively to ease her pain and guilt. She doesn't want to attend the New Year's concert the ESP has arranged, but knows she will have to attend or else it will anger him. In an earlier conversation, the ESP tells Luna and Persona that they are still under his command and that they will use the concert as an opportunity to ambush Z, as well as trick Mikan into breaking the contract so he can gain use of her Alice. When Luna tries to protest, the ESP tells her that they are meant to be together (the false affection he shows her to get her to do what he wants) and that she needs to do what he says. Unsure of what to do, Luna doesn't say anything. However, when she is ordered to help capture Mikan, she doesn't do so and even allows the Fuukitai to get defeated by the Dangerous Ability Class. However, when the ESP learns of Persona's betrayal, he sadly asks Luna to capture Mikan and that he knows she would never betray him. Because of his

Luna killed ESP

words, Luna, although still feeling guilty for Yuka's death, realizes that she still can't leave the ESP because she indeed promised to never leave him no matter what. She and a group of Fuukitai confront Mikan and Persona, and commands the Fuukitai to attack them. Mikan uses a large amount of her Stealing Alice to stop the Fuukitai and controlled students. The Fuukitai are then stopped by the students as Mikan and Persona escape. Before leaving, Mikan tells Luna that she hopes Luna will come to like her Alice and live peacefully, which softens Luna. She then finds the ESP surrounded by Natsume's flames. When the flames disperse, the ESP orders the Fuukitai to capture Mikan and Natsume, and to attack Tsubasa. Before he can act, Luna hugs the ESP from behind and asks him to stop with his evil acts. She confesses that she tends to stop him by using her Alice on him to take his soul. While she says that he has become obsessed and pitiful to the point where she is disgusted with him, she will always cherish him and will stay by him until the day he dies. After taking his soul, Luna holds his body and mourns for him. She then reveals to the HSP that she is suffering from the same condition as the ESP due to her eating too much Gulliver's pills to take on her previous child form. Although they offer medical treatment, she refuses because she wants to endure what the ESP has endured. Luna looks over at Mikan and apologizes to her for all the things she did to her.


Luna has a Soul Sucking alice which gives the ability to control others and leave a bite like mark behind if she sucks some of the person's soul out. The victim does not remember the events happening while being controlled. Explained by Yuka, if Luna sucks all of the person's soul, that person will die. She has been shown to able to control multiple people with her Alice and able to use their Alice to her advantage. The only one shown to stop her Alice is Mikan by using her Stealing Alice to take Luna's Alice stones out the victim's body. She may have the Limitless Alice form, since in her introduction she coughed up blood. When Luna was young, Yukihira gave her Alice restraining piercings.


  • Luna's Alice is similar to the legendary creatures succubus (Soul Sucking) and vampire (the bite marks left behind).
  • Luna means "moon" in Latin. The moon can be a reference to a crazy person, possibly reflecting Luna's unstable mind.
  • Luna has had her Alice stolen twice, once by Mikan, and the other by Yuka.
  • Luna's Alice stone color is black.
