Ruka is french from his mother's side. He has blonde hair that parts in the middle and light blue eyes. He wears the standard elementary uniform that consists of a black jacket, white collar with his red bow tied. He also wears red plaid pants and black boots. Ruka doesn't wear his three stars on his collar (thinking he didn't deserve it) and he later threw them out saying he's like Mikan, a No-Star.
Ruka is a little nicer and can be considered more bearable than his best friend Natsume. While Natsume is cold and distant, Ruka is warm and pleasant to people. Like Natsume, his classmates see him as serious and cool, but Ruka really isn't that type. He is an animal lover, which corresponds with his Alice. Ruka has been shown to be embarrassed by his Alice and Hotaru noted early on in the series that people never saw his Alice, but were aware of what his Alice was. When he meant Natsume he was embarrassed of his Alice, but was told by Natsume that his Alice was a gentle type that could help people. He often falls victim to Hotaru's blackmail when she takes pictures of him in embarrassing situations and selling them to his fan club for money. For that reason, he disliked Hotaru, though the two later form a truce and understanding for the other.
He is a very loyal friend, especially to Natsume, and later Mikan. Ruka knows of Natsume's sacrifices and feels helpless that he can not help his friend. Such that, Ruka feels that he is a burden to Natsume because the school gave him his star rank based on making Natsume do dangerous missions and that the school threatens to harm Ruka if Natsume disobeys. Ruka even claims that when Natsume is in pain, he is in pain. When Mikan, back in the Northern Woods Arc, made a comment on Natsume's scary personality, Ruka was noticably angry at her words, because of how much of Natsume goes through. His loyalty is most admirable in the Hana Hime arc, where Ruka used mice to fight with, even though he hates using them for such things. But having his friends in danger had him make an exception. In addition to watching Natsume suffer, he is saddened to watch Mikan make unbearable sacrifices to protect her friends and suffer the consequences.
Almost immediately, Ruka becomes attached to Mikan due to her cuteness and cheerful personality. He makes attempts to befriend her and understand her, even if he thinks Natsume will oppose, after noticing that the academy is, too, targeting her. He tends to blush when he sees her in cute clothing or when she says something cute. While his feelings become that of romance, it makes him vulnerable for his fan club to tease him. When they realize they both love Mikan, Ruka and Natsume have a sort of rivalry over Mikan and both say they don't want to lose to each other. He even asked her if she would like to switch Alice stones with him during the Z arc, even though she didn't understand the meaning of the switch then (the switchers would be soulmates). However, while they look into Yuka's past, he discovers that Mikan and Natsume's mothers had been best friends and Nodacchi commented how of a miracle it was for Mikan and Natsume to meet in the academy. This makes Ruka realize that Mikan and Natsume were meant to be together. Telepathically, he allows Natsume to be with Mikan because Natsume needs Mikan and she needs him. He admitts to Mikan that he loves her but he tells her that Natsume is the only one for her and he will support them because he loves them both very much.
Like many Alice children, Ruka was targeted by the academy and went through several kidnappings. All this caused his mother to be very protective of him. To get away from the academy, his family moved several times until settling into a small village. His mother used her money to buy around the clock bodyguards for Ruka and keep them around the house at all times. She also like to call him ‘Ru-chan’. Around the village, he was quite famous for being an Alice. A girl called him the "pride of the village". However, due to the burden of being an Alice and of his mother's over-protectiveness, he began to feel like a bird trapped in a cage.
One day, when Ruka was eight, Natsume Hyūga moved into the village, and on the first day of school, saved him from kidnappers. By saving him, Natsume had to reveal that he, too, was an Alice. Before this kidnapping, a girl told Natsume that Ruka was an Alice. The similarity between the the two resulted in them becoming quick friends, along with his[Natsume's] sister, Aoi Hyūga. Natsume and Ruka's friendship grew which made his mother realize that she needed to let Ruka have freedom. On the day, he spent the night over at Natsume's house. However, the next day, Aoi fell ill and her Alice burned the town down. He and Natsume helped civilians during the fire. However, Natsume took the blame for the fire to protect Aoi and the civilians grew to hate him. When Ruka tried to defend him, Natsume purposely hit him at the hospital, so that Ruka wouldn't be troubled. Ruka chose to go to the academy with Natsume which his mother reluctantly agreed to, seeing Ruka had grown up so much. Ruka also explained to his mother that his decision to go because he wanted to support Natsume. In the car, he and Natsume cried when they saw Mr. Hyūga, who is handicapped, run after the car to stop Natsume from leaving and they vowed to be strong.
Once they arrived at the academy, they were both looked down upon by the older students (Natsume for his rebellious attitude and Ruka for being friends with him). However, their classmates idolized them, but both paid little attention to them. Ruka tried to defend Natsume against the false rumors about him, but wad prevented by Natsume. He wad also aware of the dangerous missions Natsume did in order to prevent the Elementary Principal and Persona from harming Aoi and Ruka. This made Ruka feel like he wad becoming a burden to Natsume, but continued doing what he could do to support him.
Welcome to Gakuen Alice
He is ten years old when the series first begins. Ruka is first shown flying with the help of a huge bird and crashing into the window where Mikan Sakura and Natsume are. Natsume then asks him what took him so long and Ruka says he asks who that person (Mikan) is and if she is an Alice. Ruka doesn't stop Natsume from bullying Mikan and even asks him to use his alice on her if she is bothering him. But he wonders why Natsume has not use his Alice on her right then. Natsume replies that it does not work. Natsume and Ruka then leave out the window when Misaki and Narumi arrive.
When Mikan is assigned to sit with them, she reacts with shock and dismay. They, on the other hand, are indifferent to it. When Natsume gives Mikan the task to go to the Northern Woods to prove to everyone she is and Alice, Ruka questions him about his reasons for it. He asks Natsume if something special about Mikan caught his attention, which Natsume denies.
Ruka escapes from his class to go to the barn to see the animals, whom he gets friendly with. However, he hears the animals from the Northern Woods cry out that they are scared and he goes to the woods to help them. This turned out to be trap by Mikan, Hotaru, and Inchou (using his Ilusion Alice) who have been having trouble with the giant chick, Piyo. Hotaru remembered that Ruka has the animal pheromone alice and he gets captured by Mikan, Hotaru Imai, and Inchou. Ruka initially refuses to help them until Hotaru says that she will have to deal with Piyo with her inventions. Ruka tells them not to look, but they do anyway without him knowing. The Middle School students take Piyo back and Ruka says goodbye. He becomes embarrassed when he saw that everyone was watching and runs away, but is stopped by Hotaru who has a picture of what happened. Mikan gives in some insight that he seems nicer than Natsume and insults on how cold Natsume is, which makes Ruka upset at her. He says that she is has no right to talk that way about Natsume when she isn't the one who always suffers and has an unwanted Alice. When Natsume arrives at the scene and uses his Alice on the group, Ruka tries to convince Natsume to stop, but is unsuccesfull. When Natsume accidentally burns a rabbit, Ruka tries to help it. In the end,Mikan's Nullification Alice stops Natsume's flames. When Natsume wakes up, Ruka helps Natsume back on his feet and the two leave before that guy (Persona) comes.
After the Northern Woods
He is in class when Natsume comes in with injuries that were not there before and is shocked. He tries to ask what happened, but Natsume assures him that he is alright. He sits quietly as Mikan is bullied mercilessly by their classmates and teachers, and earns a no star due to a prank done on her to make her teacher hate her. He later warns Mikan that she might be targeted, because what happened should of not made her a no star. Some time later, Ruka is accidentally placed on Mikan's team for the dodgeball match when he was tring to go to on Natsume's team. Although he wanted to be on Natsume's team, Ruka encourages Mikan to keep trying when their team was losing. Like everyone else, he eventually gets into the game and has a good time.
Ruka sneaks into Mikan's room to give her food on Hotaru's request. He then helps Mikan who wants to escape by providing her a bird to escape and dressing as a girl to replace her. Unknown to him, Hotaru took pictures and he confronts her in the next chapter. He and Hotaru find out about Narumi trying to leave to talk to Mikan's Grandfather.
Ruka's Somatic Class is one of the most popular classes during the Alice Festival, so he has to help out a lot. However, he escapes during class to see Natsume, who skipped and is not allowed to participate in the festival. Along with Sumire and Youichi, Ruka goes to the hospital to see Natsume, who has fallen sick due to his illness. Later on, when Natsume is kidnapped by Reo, he helps Mikan and Sumire escape by having his bird friends distract their pursers. He stays in the teachers lounge with Hotaru and the teachers to keep in touch with Mikan about the situation. When Natsume denotiates the warehouse in anger over how Reo's men injured Mikan, they are returned to the academy and hospitalized. Ruka visits Mikan and thanks her for saving Natsume, showing his acceptance towards her. .Alice Festival Arc
Ruka smiles at Mikan and is more friendly with her days later, which makes a lot of stud
ents aware that he is growing to like her. He, Sumire Shōda and Narumi go to the Special Ability Class’ RPG game because they had nothing to do. While there, everyone commented how his bunny ears made him look cute (including Mikan which made him embarrassed). Ruka blushes when he sees her in her genie outfit and thinks she looks cute. He became one of the first challengers for the RPG game, his weapon was a rope. He lost on the first round, because he could not figure out which was the real Misaki Harada before time ran out.
Natsume later shows up looking for Ruka and is confused of his bunny ears. Ruka and Natsume then get jealous when Tsubasa hugs Mikan. At the end, Mikan is accidentally made a slave of Natsume’s after he wins the game and Ruka offers to help her when she voices her displeasure. During a conversation on everyone’s dreams for the future, Ruka tells Mikan his dream to become a veterinarian. For the Somatic Ability Class play, Ruka is playing Snow White in the a play and asks everyone not to come, but they do anyway to see his costume. All the girls talk about how cute he is, which puts him in a bad mood. A accident with slime balls occurs that put most of the cast out and having Mikan play the prince in the play. Mikan puts on her prince costume, which makes Ruka blush and he wanted to say she looked cute but instead comments how this is the first time he has seen her hair down. Both promise to give their best, given both have never been in a play before. The play starts and he and Mikan are in a tower scene with Permy/Sleeping Beauty saying she will separate them. In the next scene Ruka is with the fake animals and then the real animals that are in the
audience come on stage and sing along. The scene changes and now Ruka is with Narumi who says that he will kiss him causing the animals to attack Narumi. Ruka is then with the dwarves where he gets bitten by a poison apple. Mikan is told to kiss Ruka on the lips by Narumi, which makes both uncomortable. However, they attempt to kiss for the sake of the play, but are interrupted by Natsume, who throws an eraser (or apple in anime) at Mikan, and Hotaru, who shuts off the lights, ending the play. Afterwards, Mikan and Ruka are shy around each other, but congratulate each other and say they did a good job in finishing the play. During the Alice Festival Last Dance, he and Natsume have many
girls who want to dance with at the last dance. but both have no desire to dance with them. During the dance, Ruka wants to dance with Mikan but can't bring him to say so when she asks if either of them want to dance with her. Natsume pushes Ruka to Mikan so that he would dance with her. Mikan and Ruka enjoy dancing with each other. After Mikan and Ruka finish their dance, Hotaru then grabs Ruka's hand and tells him that Mikan is so dense, which he does not understand. When he goes to get a piece of cake, he overhears Mikan and Natsume talking and hears Natsume call Mikan by her first name, which surprises him. He is further surprised when he sees Mikan blushing as she walks away, this leads him to believe that Mikan likes Natsume. When he sits with Natsume, he mentions that he called Mikan by her name and says that Natsume should dance with Mikan. They bicker over this until Hotaru chooses Mikan as her last dance partner, which makes them laugh.
Days later, Ruka sees Mikan and her friends study for the semester exams. Although he didn’t intend to study, Ruka, along with Natsume and the rest of Class B, feels compelled to join the study session.
After linchou's Alice is stolen, Ruka visits him in the hospital and later witnesses an altercation between Mikan and Natsume, who declares he hates Mikan. Ruka, however, remembers when Natsume claimed to have hated strawberries so Aoi could eat them, and he concludes Natsume doesn’t hate Mikan. Hotaru later is injured by a Z member after the organization invades the academy. Ruka goes to the hospital to see her and sees Mikan devastated that she wasn’t able to do anything for Hotaru. Ruka hugs her in his arms as she cries. To get a cure for Hotaru, Ruka, Mikan, Natsume, Tono, and Tsubasa decide to sneak into the
high school section to use the rumored Warphole to go Z's hideout. Ruka, Mikan, and Natsume must disguise themselves as high schoolers using Gulliver's Candy. He is flustered after seeing Mikan as a high schooler, and Tono comments that even though he is older on the outside, inside he is still a ten year old. Not long after arriving in the high school section, he and Mikan become trapped in an anti-gravity chamber they accidentely went into it after their Gulliver's Candy wore off. Ruka and Mikan are both rescued by Tsubasa's Alice. Ruka along with Mikan, Tsubasa, and Natsume use the Keyhole (actually called Keyhole and not Warphole) after proving themselves to be serious about going to Z's hideout to school council president Sakurano and vice president[Subaru]], who is also Hotaru’s older brother.
They are transported to a wooded mountain with dangerous traps surrounding everywhere. Ruka and Penguin are about to be turned into to stone by a tree but Mikan nullifies the attack using her Alice powered up by Tono's Amplification Alice. Ruka's Animal Pheromone Alice becomes a very valuable source of information for the group, with him being tasked with asking the animals which warphole Z used. Ruka and Mikan spend some time alone admiring the view of the lake reflecting the moon, the night before using the warphole to transport to Z's location. He promises Mikan that one day he will give Mikan his Alice stone and she agrees to give him hers (Mikan didn't know about the exchanging of Alice stones meaning soul-mates). Ruka is overcome with guilt when he realizes that
Natsume also has the same feelings for Mikan and leaves her to find Natsume, so he could see the view of the lake too. He later eats some grapes that Penguin brought which turns out to have alcohol in them. In a drunken state, Ruka becomes jealous of Tsubasa being too close to Mikan and Ruka hugs Mikan, but is peeled away by Natsume and falls asleep. Later on, the group manages to find the hideout but are immediately confronted by Yuka, Shiki, and several other Z members. Ruka gets infected by Z’s Boss’ Alice while protecting Tsubasa. In a stunning turn of events, Yuka offers the antidote to the children. Ruka is then healed by licking Z's Boss’ blood off a knife, given by Yuka. Then, the ceiling collapses and they flee. Despite the apparent life-threatening circumstances of the escape, they all return safely to the academy. Afterwards, all of Class B has a sleepover.
Christmas Ball Arc
Shortly after returning to the academy, Ruka joins everyone shopping for Christmas at Central Town. He also helps arrange a late birthday party for Natsume. He gives Natsume a sand clock, saying "If only we could turn back time",
which makes Natsume choose Ruka's gift as one of his favorites. During the prepartations for the Christmas party, Ruka runs into Piyo decorating the Christmas tree and helps him.
During the party, Ruka blushes as he sees Mikan dressed up nicely. He offers to help Mikan with the cleanup, due to a deal made with Bear if it played with Youichi, but she insists she can do it alone. Ruka and Youichi go on the balcony to thank Mikan for her hardwork. After Youchi kisses Mikan as a sign of thanks for giving him Bear to play with, Ruka kisses her other cheek as another thank you. This causes Mikan to become embarrassed and avoid Ruka, who is teased for daring to kiss her by Hotaru. He gets Mikan and Natsume to dance with each other since they didn't at the Alice Festival. He is surprised that Mikan and Natsume accidentally kissed, but Natsume prevents him from asking him if they did kiss. Later on, this is cleared up during the Big Clean up Day. Awkwardly Ruka, Mikan, and Natsume are grouped together to clean up the hallways by Jinno. Suddenly, the lights go out, which results in the situation being more uncomfortable. He and Natsume both notice that Mikan is scared, and to comfort her, they both at the same time hold on to Mikan's hands (Ruka holding Mikan's right and Natsume holding Mikan's left). Ruka and Natsume each wear a serious face as they compete over Mikan who is oblivious to the whole thing. A few moments later he and Natsume burst into laughter about what they are doing while insulting each other in a almost friendly manner.
Hana Hime Arc
Ruka attends Mikan's birthday party and the New Year's party altogether. During the parties, he became stuck to Hotaru and Youichi and was allowed to go to Hana Hime, but crossdressed as a girl. While at the party he is given the nickname Himawari No Kimi and fits in the party. Ruka, along with Hotaru, finds Mikan and Youichi locked in the dungeon and frees them. They then go to look for Natsume when he goes missing. At the basement of Hana Hime, they are confronted by Rui and Hayate, who proceed to attack them. Ruka uses his alice to control the mice against Rui and Hayate. He tells everyone he will take care of them so that they could get to Natsume, but Youichi Hijiri and Tsubasa Ando volunteer to. After leaving Tsubasa and Youichi, he tells the group about his history with Natsume and the series of events that led to Natsume’s enrollment.
After he tells them, Ruka, Hotaru, and Mikan split in different directions. Ruka finds Natsume and Hotaru asks Mikan to come to the path Ruka took. While there, Nobara is seen in her second personality and is ordered by Persona to attack the group. She however refuses once she sees Mikan. As Persona uses his Alice, Ruka tries to protect Mikan, but one of the mice gets killed in the process. When Aoi appears, Ruka recognizes her and becomes paralyzed by Yakumo's insect along with Hotaru and Mikan. When Mikan gets infected by Persona’s Alice to stop him from hurting Aoi, Ruka fears for Mikan’s well-being, as a victim of Persona’s Alice will die from the effects. After bringing Mikan to the hospital, Ruka suggests that since Aoi is not an Alice, she should be allowed to leave. As Mikan’s condition took a turn for the worse, Ruka is greatly distressed and has to restrain Natsume from panicking as well. Ruka later helps spread the news of Aoi’s imprisonment to help her get released from the academy. Days later, Ruka and everyone else say their goodbyes to Aoi. When Mr. Hyūga arrives to pick Aoi up, Ruka’s mother also arrives and he hugs her through the gate, though he and Natsume are escorted away from the gate. As he hears Mikan talk about not being able to see her grandfather due to her star ranking, Ruka chooses to throw away his stars and states that now he is like Mikan, but this did not change his star rank.
Ruka later joins Natsume who is sitting on a tree. Natsume jokingly calls Ruka a ‘No Star’ and laughs. Ruka comments how Natsume is able to smile and laugh due to Mikan, and says he knows Natsume chose to stay in the academy because he wants to protect Mikan, which Natsume confirms and admits he is in love with her. Ruka also admits his feelings for Mikan and vows to never lose to Natsume.
On Valentine’s Day, Ruka and all the boys hide from the girls due to the girls putting weird ingredients in their chocolates. Ruka hides in the classroom when he is found by Mikan. She offers her chocolate to him and he accepts. After she leaves, Ruka also decides to leave but accidentally leaves the chocolate, which is found and eaten by Natsume.
For the lesson on making Alice Stones, Ruka is able to make a small size stone and he participates in the game to find someone to exchange Alice stones with in the dark.
When Yura is due to graduate, Ruka agrees to be part of a band but Sumire and her friends are chosen by Jinno to form their own band while everyone else is not allowed. However everyone makes up on the day of the graduation. A month later, as Class B enters in the sixth grade, Ruka confronts Natume about continuing to do missions and going to the hospital. Natsume tried to reassure Ruka that he is doing less dangerous missions and his actions are to protect Mikan. When Mikan asks where Natsume has been during spring break, Ruka lies he was traveling.
Luna Koizumi is enrolled into Class B as a new student but Ruka, along with Natsume and Hotaru, suspect she is not normal when she exhibits malicious behavior towards Mikan. Ruka later witnesses Luna slap Natsume for insulting her and commenting how his eyes are like his dead mother’s. Ruka is placed on the White Team with Mikan.
With Hotaru and Natsume, Ruka attempts to rescue Mikan when she got captured by the Fuukitai. When they are confronted by Tsubasa, they choose to leave the matter to him. Ruka and Hotaru then spy on Tsubasa's and Natsume's conservation about Tsubasa being the Dangerous Ability Class and Yuka being Mikan's mother. Ruka is later a participant in the Obstacle Race. He was able to pass the lake stage by flying over it with a bird. He then finishes the race and wins by gaining the trust of the robot horse with the help of the other animals. This gets him the praise from Mikan he wished for and the two spend some alone time eating a picnic together.
A prank caused by a infamous gang, the Tehoran, causes Ruka to switch bodies with Hotaru and Hotaru to be in Mikan's body. He is not alone, because others are caught in the fray, Mikan, Sumire, Bear, Natsume, Iinchou, and Koko, respectfully have also switched bodies with other another. Since he's in Hotaru's body, he comforts Mikan who is in distress for being in Bear's body. Later Ruka would bump into Natsume who is in Ruka's body and returns to his body, which would mean Natsume is now Hotaru. Ruka then leaves Natsume-Hotaru to search for Natsume the person he was looking for, not knowing Natsume was right in front of him.
Ruka and all of Class B help Mikan and Natsume escape from the Elementary Principal, which causes them to get punished. Ruka is saved by Noda while his classmates are thrown in a prison cell, and Ruka is reunited with Natsume and Mikan. Ruka, like Natsume, defends that Mikan should choose her own path and travels through the past along with Hotaru, Natsume, and Mikan.
Time Travel Arc
Like everyone else, Ruka is saddened by Yuka's past and gives Mikan support. After discovering that Mikan and Natsume's mothers had been best friends, Ruka realizes that Mikan and Natsume are meant to be together. Telepathically, he announces his decision to let Mikan be with Natsume because he is aware they love each other. When Natsume gives him a troubled look, Ruka smiles and assures him that he will support them because he loves them both and wants them to be happy. Like everyone else, he creates and gives Mikan a Animal Pheromone Alice Stone to help her in the outside world.
High School Division Arc
He and the group return to the HSP's office where a fight ocurred caused by the ESP. When Natsume almost uses his alice against the students after them, Ruka warns him to stop, so Natsume would not suffer again. When Ruka saves Mikan from a bird almost flying into her it is learned he gained the Barrier Alice. Ruka senses the Dangerous Ability Class students coming for them and the group teleports, except Nobara Ibaragi who stays behind to fight them herself. Ruka is fatigued from using the barrier alice so much and almost collapes, but he reassures to everyone that he is alright.
He almost collapses again, but this time he accidentally opens the barrier a bit, which results into the Fuukitai finding them. Ruka is then given the task to take Mikan to the Keyhole and to protect her, since he is the only one who can. As they are running away, Ruka confesses to Mikan that he loves her, but knows that she and Natsume belong together, so he gives them his prayers.  Ruka appears to becoming increasingly tired from using the Barrier Alice, yet he refuses a request by Mikan to rest, knowing that she is tired also, and that they need to get to the Keyhole.
Ruka and Mikan make it to the Keyhole and Tuka witnesses Mikan and Natsume share an embrace. Yuka and Shiki arrive before the Fuukitai arrive, and Yuka attempts to unlock the door before it explodes, which kills her. Ruka is saddened by Yuka’s death but when Hoshima grabs Mikan and the Elementary Principal arrives, Ruka is prevented from helping her by the Fuukitai. He and the others are then forced to be witnesses to a deal between Shiki and the Elementary Principal in which the Elementary Principal will spare the students from punishment for reveling in return he will share guardianship of Mikan with Shiki and allow the barrier to be repaired so Z won’t invade.
Ruka watches Yuka’s funeral with the other students but when he sees Mikan leaving with the principals, he asks where she is being taken. Mikan doesn’t answer but buds everyone farewell.
Three months later, Ruka feels the academy is not the same without Mikan and wonders where she is. Because she is not allowed to attend the Christmas Ball, Ruka and all of Class B decide to send her fairytale books as Christmas gifts. His chosen book is called the Star Money. His message to her says, "The girl in the story [The Star Money] is just like you, Sakura."
During the Christmas party, he, like everyone else, is saddened that Mikan really couldn't come to the party and sees Natsume leave to go look for her. He later finds Natsume laying in the snow and asks if he's going somewhere again. Ruka is thrilled that Natsume and Mikan were able to see each other and says Christmas is amazing. He then catches Natsume coughing up blood and says that he's known about it for a long time. Ruka asks Natsume not to hide his pain, but let him be his supporter and that he doesn't regret coming to the academy with Natsume. Ruka also says that he will always support Natsume and Mikan's future when
Natsume tells him of his fears of dying and leaving Mikan alone. Natsume makes Ruka promise to take care of Mikan if something happened to him in the near future, which makes Ruka worry on what Natsume is actually planning. He is given mushroom earplugs by Hotaru, along with all of Mikan's friends, because of the suspicious circumstances on why Reo is allowed to host the New Year’s concert. He and Natsume eavesdrop on Reo bragging about his plan to assasinate the Elementary Principal and they are shocked. Ruka asks Natsume what they should do, but they are interupted by Tsubasa and Tono, who wish to help them out. Tsubasa and Tono explain to Ruka and Natsume that the only way to bring peace to the academy is to eliminate the Elementary Principal but they must be prepared to also face Z if the two are joining forces. During their conversation, Koko reads Natsume's mind and says out loud about Natsume proposing to Mikan. Surprised and a bit hurt that Natsume hid this from him, Ruka asks about Mikan's reply, which she accepted, and he congratulates Natsume. Then Koko reveals Mikan and Natsume's many kisses, which makes Ruka even more mad and he hits
Natsume in a friendly manner while saying he should not hide things from him anymore, and that he will always support them. On the day of the concert, the boys split up to prepare their plot to assasinate the Elementary Principal. Ruka grabs Natsume and tells him that he must be careful and not leave his side. Ruka knows that Natsume is planning to risk his life if it means to save Mikan. Ruka takes part in the battle and is forced by Hotaru to stay with Natsume, Tsubasa, Tono and the teachers to fight the Elementary Principal while she and the other students teleport away for their safety. In midst of the fights with the Fuukitai, Ruka is badly injured but takes a blow to save Natsume when he starts coughing up blood. They soon reach the Elementary Principal’s room and rushes to Natsume's aid after he is stabbed in the back. When Natsume sets the room on fire, he asks Ruka to get everyone out safely. Ruka asks him if he's coming and Natsume says no because he wants to kill the Elementary Principal himself. When Ruka protests, Natsume tells him that before he dies, he will see Mikan's smile again and reminds him of their promise on Christmas Eve. He blasts Ruka and the others away with his flames and Ruka reluctantly leaves. But he tells Tsubasa that he saw the look of wanting to protect someone in Natsume's eyes, and that for the first time, Natsume has taken it upon himself to protect everything conerning the well-being of the academy. Tono
takes Ruka outside and they deal with some Fuukitai while Tsubasa runs back to Natsume. When the smoke from the building begins to disappear, Ruka senses that something is wrong with Natsume, and is teleoprted back inside with the rest of his classmates. Ruka finds Natsume having a near death experience, and, like everyone else, panics when Mikan fails to save Natsume. Hotaru, Subaru, and Nodacchi then take Natsume back to the past to find a way to save him. Ruka worries about Mikan's well-being for the next week, and he is thrilled when she is finally allowed to return to class.
