Yuno Gasai [Zombie Apocalypse.]

Race Human Age 14 Gender Female Height 160 cm Eyes Pink Hair Pink Occupation Future Diary Owner Junior High School Student God of Time and Space Relatives Ushio Gasai (Adoptive father) Saika Gasai (Adoptive mother) Yukiteru Amano (Lover) Appearance: Yuno Gasai is a young teenage girl with pink eyes and long pink hair tied in pigtails, two strands of hair hanging as frontal locks featuring a pair of red bows, and the back pigtails left bare. Her most common attire consists of a blue shirt with a ribbon on her chest accompanied by a blue skirt with high socks (school uniform), but her wardrobe changes occasionally throughout the series. Personality: Yuno's personality is ambiguous. For the most part, she is sweet, feminine, and sometimes shy when around Yukiteru. But, this masks her dark and sanguinary side—ruthless, cold, and calculating. She has little, if any problem with using and taking advantage of others for her goals: her and Yukiteru's survival. She will resort to cruel and usually violent methods, most of the time coming out of nowhere, that generally end in bloody deaths, of either a Diary Holder or their followers, effectively making her a Yandere.

Her brutal personality mostly results from abuse inflicted by her mother and the absence of her father, which finally ended with their deaths two years prior to the Survival Game. This was the beginning of her changes, as she later became quite lonely and sorrowful. This is shown in her somewhat morbid habits of talking to her parents' dead bodies, telling them about her day and claiming she will bring by Yukiteru. She even took their heads with her when she trapped Yukiteru in a hotel, and when Aru Akise moved their bodies, she became angry and said her parents were sleeping and that he "woke them up." These events also show her complex feelings about her family. Although she wanted them to feel and understand the pain she experienced because of their abuse, she essentially just feels deeply betrayed by them. She wanted them to be a happy family, but because of their neglectful behavior and their deaths, she felt like her life had no purpose. Thus, when Yukiteru told her they would get married when they grew up, he unwittingly became a pillar of support that gave her much-needed stability. Her obsession with Yukiteru grew to escalating proportions to the point that she was willing to harm those who she believed would take Yukiteru away from her, be they friends, rivals, relatives, other girls, etc. She was prepared to resort to violence if Yukiteru's mother ever opposed her (which did not happen), stating that she did not "need her tools." Furthermore, she threatened to kill Tsubaki Kasugano, and immediately panicked that Yukiteru's friends Aru Akise, Hinata Hino, Mao Nonosaka, and Ouji Kosaka would take Yukiteru away from her, forcing Yukiteru to calm her down and announce their official "relationship", much to Yuno's joy and his own despair. At one point she even kidnapped Yukiteru and held him hostage because she was so terrified that another diary user would kill him.

At one point she even kidnapped Yukiteru and held him hostage because she was so terrified that another diary user would kill him. Aru has stated that Yukiteru provides a stabilizing influence in her normally chaotic and violent life. Despite her insanity, Yuno has shown some reservedness to killing. This is shown when, after Yukiteru calls her his girlfriend, she instantly lets Hinata go when she intended to slit her throat. The fact that she did this, rather than killing her anyway, to ensure that there was no chance Yukiteru would fall for her suggests that she doesn't actually enjoy killing; she merely does it because she sees no other option. It is shown many times in the series just how deeply insecure Yuno truly is when she says her life would not be worth living if she could not be the center of Yukiteru's world. Her crippling fear of losing him is notably the only thing that can cause her usually disturbing composure to crack. In the third world, Yuno seemed to be very nice and calm, possibly because she still had love for her parents and there was no survival game for them to participate in. This allowed Yuno to stay mentally sane. However, as a side effect of receiving her First World self's memories, it is implied that she might still remember some of the things that occurred in the first world as she states that she feels as if "something is missing."

Yuno was adopted by her parents at a young age, her umbilical cord left to her as a present from her original parents, but was kept at the orphanage. Yuno's life was a happy one for several years until the strain of money began to emotionally and psychologically affect her parents. Yuno's father stayed away at work until the late hours and barely interacted with his family. Yuno's mother began to abuse her, wanting her to become the "perfect citizen," eventually locking her in a cage and timing everything she did, from sleeping to eating. Yuno's mother went to the extreme, leaving Yuno to starve and at times force-feeding her inedible materials, although it is implied in the anime that Yuno did this to herself to survive. While Yuno's father objected to his wife's severe treatment of Yuno, he did little to nothing to stop her. In the anime, Yuno's mother was ill and believed she was a terrible wife and mother, and believed punishing Yuno was her only way to earn happiness. Eventually, Yuno snapped and managed to imprison her parents in the cage as punishment. However, she neglected to check in on her parents and they starved to death. Not removing the corpses from her house, Yuno began to act like they were still alive and talked to them, her home's electricity cut off due to unpaid bills. Now with nothing left to live for, Yuno fell into despair, to the point that she was put in detention at school to write up her dreams for the future. Not having any dreams, Yuno turned to the only other person in the classroom: Yukiteru. Asking him what his dreams were, Yuno learned Yukiteru wished to go stargazing with his parents who had recently divorced. His dreams seemingly ruined, Yuno suggested seeing the stars with him. While Yukiteru objected to going with her instead of his family, Yuno proposed becoming his "bride". Believing Yuno to be joking, Yukiteru agreed but only when the pair grew up.

However, in Yuno's view, she believed Yukiteru was serious and her whole life became focused on him. Observing him from afar, Yuno stalked Yukiteru. A week after their meeting, Yuno learned Yukiteru had a love letter, planning to give it to fellow student Moe Wakaba. Realising her chances to be with Yukiteru were in jeopardy, Yuno dressed herself up in a pink rabbit costume to stop Yukiteru from giving Moe the letter. Her attempt ultimately failed, but Moe kindly rejected Yukiteru's feelings towards her. Relieved, she kept stalking him.

At the beginning of the manga, Yuno is introduced as the ideal student, with good grades and popularity. Already having her diary, Yuno kept an eye on Yukiteru until April 23rd when Deus activated the survival game. On April 24th, Yuno realizes Yukiteru has gained his Future Diary and creates a clay model of Muru Muru on her desk as a clue to Yukiteru that both of them are Future Diary Owners, and that Deus is not imaginary. She then approaches him after school. Yukiteru runs off in terror, much to Yuno's surprise, until he flees into an elevator of a building. Yuno catches up and joins him in the elevator to save him from the Third. Yukiteru tries to pull out a throwing dart to defend himself, only for Yuno to kiss him full on the mouth, stopping him. Yuno explains the survival game, how she and Third are diary owners, and reveals that her phone focuses entirely on Yukiteru's actions. She averts Yukiteru's future by sending the elevator to the top floor instead of the fourteenth, where Third would have killed him had she not intervened. On the roof, Yuno swiftly formulates a plan and instructs Yukiteru to destroy Third's diary using his throwing darts. They hide when Third appears on the roof. Yuno catches Third off guard when she runs out in front of him, allowing Yukiteru to throw a dart and pierce Third's phone, erasing him from existence. Later, Yuno, Yukiteru and the other diary owners are gathered by Deus who explains the rules of the game. Afterwards, Yukiteru finds himself alone in the Cathedral of Causality, Yuno appearing behind him and vows to protect him no matter what, terrifying Yukiteru with her adoring look of joy.

After sending forty text messages to Yukiteru, Yuno is thrilled to be in his company again. The next day, Yukiteru approaches Yuno to ask for help in the game, although she departs to a P.E. class with the promise to talk to him later. However, Minene Uryu, the Ninth diary owner, arrives to kill Yukiteru. Yuno attacks her with a fire extinguisher and manages to save Yukiteru from the first bomb exploding in the middle school. Yuno promises Yukiteru to protect him. Afraid of dying, Yukiteru plays along with Yuno in order to protect himself and the two share a kiss. Sneaking through the school, the duo use their diaries to evade most of Minene's bombs but eventually are lured into a trap and caught in a blast. They survive but Yukiteru laments over his decision to be a bystander, however, Yuno reveals she has been watching him for a while and promises him that the other students and staff members are his friends. The two make it to the other side of the school, only for several students including Ouji Kosaka to ambush Yukiteru and drag him outside to be sacrificed to Minene. Yuno is taken into a classroom where she watches Yukiteru falling into despair. Realising she lied to Yukiteru, Yuno vows to protect him. She frees herself from her captors and races out of the school, causing all of the motion-sensor bombs to go off until she eventually leaps out a window and tries to launch a surprise attack on Minene. At this point, Kurusu Keigo, the Fourth diary owner, has arrived to aid Yukiteru. Yukiteru charges at Minene, Yuno using her Yukiteru Diary to help Yukiteru avoid the landmines between him and Minene. Minene realised that Yuno is a Diary Owner as well, kicks Yuno away, leaving Yukiteru to use his common sense to dodge the final mine and wound Minene in the eye with a dart. Minene retreats on a motorbike using her Escape Diary.

Later, Kurusu forms the Future Diary Alliance with Yukiteru and Yuno. Yuno reads her diary, finding the "Happy End" entry on July 28th, predicting that she and Yukiteru will come together as one. Kurusu arranges for Yukiteru and Yuno to visit Sakurami City's amusement park in order to lure out Minene. Yukiteru and Yuno spent the day together, Yukiteru observed how Yuno did have a normal side after all. Yuno tries to go to the planetarium, but Yukiteru deliberately avoids it, choosing to go on the nearby ferris wheel instead. Yuno confronts Yukiteru about his odd behavior, reminding him of their past encounter and the promise they made go stargazing together and become a couple, much to Yukiteru's shock as he realised that Yuno took his joke seriously. Yuno gives Yukiteru a kiss on the forehead afterward. Yukiteru escorts Yuno to her house, although Yuno invites him inside. The electricity is out, and Yuno disappears into the kitchen to prepare an apple for her and Yukiteru to share. Yukiteru wanders off into the pitch black house to find the bathroom but comes across the sealed off room where the three corpses are. Reading the entries in his diary which only briefly note the door, Yukiteru decides to experiment and alter the future by looking inside the room. As he opens the door, all of the Future Diaries are completely rewritten. Yukiteru opens the door and finds the three corpses inside, altering the planned out future of the survival game and nearly destroying Deus' Cathedral of Causality. Yuno finds Yukiteru, horrified at what has happened, her diary's "Happy End" vanishing. Yukiteru flees her home in terror, running to his own house and locking himself inside, where he collapses by the door to catch his breath and regain his energy. Yuno follows, suddenly looking through the letterbox and wishing Yukiteru a good night.

The next day, Kurusu arrives at Yukiteru's house to pick him up, but as Yukiteru tries to tell him about the discoveries of last night, Yuno comes out of Kurusu's car, telling Yukiteru not to give away "what happened". Kurusu immediately assumes the two got up to something private and hops into the car, Yuno giving Yukiteru an innocent smile. Yukiteru, still cautious, hops into the passenger seat but has Yuno staring at him from behind all the way down the highway. Kurusu explains that Minene was captured overnight by the Omekata Temple cult, led by priestess Tsubaki Kasugano who is said to be able to predict the future through clairvoyance. They agree to meet the priestess in order to obtain and seize Minene. When they arrive at the cult, Yuno watches Yukiteru as he approaches a pond while Kurusu talks to Orin Miyashiro. She catches him when he falls on his back, and finally accompanies him when Kurusu calls them. Tsubaki meets them and agrees to an exchange: she would hand over the Ninth in exchange for the First, since her diary has predicted her Dead End that night and he has escaped from the Dead End twice. Yuno immediately disagrees, but Yukiteru agrees to the deal and goes with Tsubaki. That night, the cult followers fall into a deep state of hypnosis and become puppets for the Twelfth diary holder. They begin their attack against their leader, setting her chamber on fire. Armed with an axe, Yuno attacks and kills various followers to protect Yukiteru, but then she notices him running towards Tsubaki to save her. She catches up with him quickly and tells him that he has to either leave Tsubaki behind and join her or he would die. However, he tells Yuno he wasn't going to leave her behind with the addition of calling her crazy, then hurries to Tsubaki's cage, leaving behind a crying Yuno.

Luckily, Kurusu was able to put down the fire by turning on the sprinklers, saving Tsubaki, Yuno and Yukiteru. However, the cult followers were still under the control of the Twelfth, so Yuno decides to lead Yukiteru (and Tsubaki, after he insisted on saving her too) towards the exit and leave the place. On the way, however, they are intercepted by the Twelfth himself, who is disguised among other four who look exactly like him. The five Twelfths race towards the trio, but Yuno (remembering the Twelfth was blind) turns that information in her favor to detect the real Twelfth and kill him in the spot with a swing of her axe. With the Twelfth dead, the cult followers regain consciousness and Tsubaki reveals her true colours as she captures Yukiteru and Yuno. Revealing she planned this all along, Tsubaki kisses Yukiteru in order to taunt Yuno, which immediately provokes her rage. Yuno sets herself free by killing the men who were holding her and is able to grab her axe and swing it at Tsubaki. She barely saves her diary, but loses one of her hands to Yuno's axe. While she screams in pain, Yuno gives her diary to Yukiteru and pushes him off the temple's bridge, letting him escape with his and Yuno's Future Diaries, which shows Yuno's trust in Yuki.

The exhausted Yuno is dragged into the temple where the enraged, now one-handed Tsubaki contemplates what to do with her captive. Acknowledging she has to lure Yukiteru back, Tsubaki sets up a microphone and instructs her male followers to strip Yuno of her clothes and rape Yuno like they did to her; while speaking to Yukiteru over the microphone and speakers to come rescue Yuno before she is molested. Yuno screams that she would rather lose her virginity to Yukiteru than Tsubaki's followers ("I was saving myself for Yukkii!"), and after thinking about her while in hiding, he decides he cannot leave her, and he charges into the temple clumsily, throwing a fire axe around. Yukiteru wraps Yuno up in his jacket and confronts Tsubaki, showing his care towards Yuno, and ultimately choosing her instead of Tsubaki, then throws a dart that pierces through Tsubaki's Clairvoyance Diary, eliminating her from the game. After Tsubaki's defeat, Yuno hugs Yukiteru's legs and cries, while Yukiteru apologizes for being "late." Later, the two are seen in the back of a police van, with Yukiteru confused by why Yuno stalks him, as he takes her face in his hand and kisses her. Yukiteru goes to meet his mother, Rea Amano, at the train terminal where she is finally arriving home from work, leaving the house unguarded. Yuno breaks into his house by using a mallet and a roll of shipping tape, preventing the glass from shattering but breaking it just enough to unlock the door and enter the house. To his horror, Yukiteru discovers that Yuno has broken in and quickly attempts to hide her from his mother, but when he finds her cleaning his room and rearranging all of his books (including his stash of naughty magazines), Rea meets Yuno. Yukiteru is quickly off-put when he finds that Rea likes Yuno and supports their relationship, so much that she allows her to stay the night in Yukiteru's room. Yuno quietly reflects to herself that she is glad she didn't have to do anything to Yukiteru's mother.

However, after being defeated, Reisuke gives Yuno a warning about her future with Yukiteru: there can be only one survivor, and they will have to eventually try to kill each other. Immediately after Fifth dies and disappears, Yuno collapses again, only for both she and Yukiteru to be saved by Ninth. Yukiteru and Yuno are relocated to a different school after Ninth bombed their old one. Here, Yuki is reunited with his former friend, Kousaka, who slams his name the second he walks in because of the terrorist incident. This is when Hinata and Mao Nonosaka show up, both aiding Yukiteru. After the morning's festivities, Yukiteru is invited to hang out with the group at the scene of a murder. Yukiteru, oblivious to any danger and eager to hang out with his new friends, happily joins along, taking a silent, begrudging Yuno with him. While the four of them have fun, Yuno sits on the sidelines. It is heavily implied that she is thinking about killing Yukiteru's new friends, especially when she traces the word "Die" in the ground with her shoe repeatedly. In this version, there are no gods, nor are there any alien worlds. In this world, a zombie apocalypse has occurred. Yuno was looking for Yukitero to save him and escape together to a safe place, but when she came to his house, he was already dead.
