Another one of Yukiteru's classmate, Ouji is in Yukki and Yuno's classroom during the previous semester and is one of the first people to betray him during the terrorist bombing incident. He writes down a list of all of his proudest accomplishments in a blog he dubs the "Kousaka King Diary", often using the phrase "I'm Shining!" after each sentence. Due to having blogged many times on his cellphone, which is connected to the Eighth's diary, he becomes a "Diary Holder Apprentice". His diary helps him save his friends, but it only reveals his successes, not his failures, which makes Yuno able to shoot him with a crossbow. Since he is inadvertently working as the Eighth's spy, Yukki destroys his diary in chapter twenty-seven, though does not die because it was not a true future diary. (Source: Wikipedia)
Houjou Reisuke is a seemingly harmless 4-year-old child. His parents were killed during the Sacred Eye incident and so he was asked to be taken care of by a co-worker of theirs, Yukiteru's mother Amano Rea. Accompanied by some drawings, his "Super Vision" diary is a coloring book that gives a small summary of the activities he will perform for the day. However, not only is there a large time gap between the entries, the diary only shows three of them per day: morning, noon and night. It does have a certain advantage of giving Reisuke all three entries at the same time, which allows him ample time to carefully plot his next move. He was killed by Second, supporting her to become God. Reisuke comes from an unhappy background where his parents neglected him and his family was gradually falling apart. He is highly intelligent for his age, yet still possesses both a child's innocence as well as a child's cruelty. Often, his actions make it difficult to tell which of the two traits is the more dominant. During his time at the Amano household, Reisuke grows fond of Yukiteru and especially Yuno; calling them brother and sister. Due to his size, Reisuke improvises with non-visual weaponry such as poison syringe and cyanide gas. He is named after Ceres —the Roman goddess of fertility.
Age: 14 years old Occupation: Middle School Student Alternate Name: First Likes: Having friends, writing in diary Height: 161 cm Weight: 53 kg The main male protagonist of the series and the First Diary user. Also known as Yuki (ユッã‚ー, YukkÄ«), he is a 14 year old middle schooler who is a rather quiet boy with an anti-social behavior who doesn't talk much. He mostly sees things around him as a bystander and writes it down in his cell phone diary. Yuki becomes involved in the Diary Game when to his shock that Deus, a god-like being whom he thought was an imaginary friend turns out to be real, selects him as one of twelve contestants in a 90 day battle royale where they must kill each other using their special diaries where the last survivor becomes Deus' new heir. Yuki's diary is called the Random Diary, which written from his point of view, gives a detailed explanation of his surroundings very accurately whether it be the present or the future. While versatile in any situation, the main disadvantage of the Random Diary is that it doesn't tells him what is happening to himself which leaves him vulnerable. Furthermore, since the diary is written from his point of view, Yuki can be tricked into thinking something he sees is true without realizing it which is a disadvantage for other people who use the Random Diary. Unlike most of the contestants, Yuki doesn't want any part of the game as he just wants to live peacefully and doesn't want to kill anyone, but is forced to play to survive and will only kill as a last resort as he is the main target by the other diary users because Deus sees Yuki as his favorite to win. Because he is weak, in order to protect himself, he quickly makes friends and allies to help him including Yuno Gasai, a girl in his class who is madly in love with him and is another diary user. Yuki is kind person yet is naive for quickly trusting people whether they be friend or other diary users as they may have ulterior motives. The most complex relationship he has is Yuno, while Yuno is a formidable ally, her mad obsessive love for him to the point she is willing to kill or use anyone so both of them can survive scares him yet despite the many things she does that shocks him. Despite this, Yuki still relies on Yuno in order to protect himself. Originally, Yuki's main goal was to find a way to end the game peacefully without killing anyone but that goal quickly changes when during the middle of the game, his mother is accidentally killed by his father, who is also later killed by agents of John Bacchus, the Eleventh Diary user. Grieving over his parents death, Yuno seduces and convinces him that in order to bring his parents back to life, he should win the game and once he becomes the new God of Time and Space, he can use his divine powers to bring them back from the dead. With this new goal, Yuki becomes determined to win no matter what including lying, killing, backstabbing and destruction. His new behavior shocks his friends as his and Yuno actions cause a series of terrorist attacks across the city. He is named after Jupiter, the Roman god of the sky, weather and lightning.
Age: 14 years old Occupation: Middle School Student Alternate Name: None Likes: Playing Detective Height: 166 cm Weight: 58 kg A classmate in Yukiteru's school, Aru Akise dreams of one day becoming the world's greatest detective. The student detective is able to correctly deduce the culprit behind the serial dog murders even before the police. He is mistaken for being a future diary holder due to his quick wits and superior deduction abilities. An additional evidence of his supernatural intelligence is shown through few arcs, where only Akise is able to compete against Yuno's analytical, deceptive mind. His physical prowess is nothing to scoff at either as he is able to overpower and out maneuver a psychotic Yuno in two encounters. His reason for involving himself with Yukiteru and the Diary affair is left vague at first. But as he participated in the investigation of the Diary Holders and worked with Masumi and Minene, and after revealing himself to be apart of Nishijima's plan to eliminate the 11th, Akise calls a meeting at his house and reveals his intentions of wanting Yukiteru to become god, yet stating his deep distrust of the 2nd, Yuno. In chapter 17 of Mirai Nikki, Akise admits in secret to Yuno that he likes Yukiteru beyond friendship, leading her to panic momentarily when he purposely wraps his arm around Yukiteru's waist to aggravate her. This might be one of the reason why Yuno is so anxious and aggravated whenever Akise is appears in front of Yukiteru. Finally, in chapter 48, Akise admits to Deus that he is in love with Yukiteru, however Deus revealed that he only made him believe he did. Akise, desperate to prove his independence from Deus' will, claims a future diary and returns, attempting to convince Yuki that Yuno is using him. Yuno attempts to kill Akise, but his diary's power allows him to forsee her actions and guard against them. Mirai Nikki Paradox He is the main character in a spin off series (Mirai Nikki Paradox) where Murumuru accidentally destroyed Yuno from existence, meaning Yukiteru is still vulnerable from the Third. So until the damage is fixed, Aru collaborates with Murumuru and together, take the place of the First and Second. When Akise sees Yukiteru for the first time, his heart thumps, causing him to wonder out loud "Is this love?" leading to confusion on Murumuru's part. He also states that his reward for killing the Third is for Murumuru to save Yukiteru. By the end of second chapter of "Paradox", Murumuru suspects he is gay because of his strange actions around a recovering Yukiteru; refusing to leave his side because Yukiteru's just too cute, stating how he could kill all the diary users to make Yukiteru 'God', and so on.
Age: 14 years old Occupation: Middle School Student Alternate Name: None Likes: Hinata Hino Height: 160 cm Weight: 47 kg Another of Yukiteru's classmates, Mao is good friends with Hinata. A willing accomplice in Hinata's scheme to kill Akise Aru. She is overly obsessed with Hinata's breast size and considers her more than a friend. Always has a camera handy.
Age: 14 years old Occupation: Middle School Student Alternate Name: None Likes: Her family Height: 168 cm Weight: 54 kg A classmate of Yukiteru and Yuno. The Tenth's daughter, Hinata is aware that her father is instigating the carnivorous hound attacks. In order to shake off suspicion from her father's pursuer, she accepts the "Rearing" Diary and uses it in her father's place. Hinata is a classmate in Yukiteru's homeroom and is the first person to reach out to him and become his friend.
Age: 14 Occupation: Maiden Alternate Name: Sixth Likes: Her family Height: 157 cm Weight: 50 kg Tsubaki Kasugano is a maiden and figurehead of the Omekata religion. Her "Thousand League Eyes" diary is unlike the other diaries, as it is a scroll, rather than a cell phone. As its name would suggest, it is able to report the future of all her followers. Unlike Yukiteru's diary, it is not limited to just her surroundings, but also sees far events, such as seeing the events Yuki had accomplished a great distance away from where she resides. Her diary can also record near events; the short-term future that will occur after only a few seconds away from the present. This provides Tsubaki with massive amounts of information to work with. However, it can pose as a hindrance in times where a situation changes constantly or when she needs to react quickly. She was born with bad eyesight, only able to see a few feet in front of her. Her parents capitalized on this by setting her up as an "oracle" and creating a cult around her. After her parents died in a car crash, however, she became a plaything for the Omekata and was even raped by it's members. As a result of her experiences, she has become jaded with the world beyond her vision, and wishes for it to disappear. Tsubaki wants Yukiteru's abilities in order to avoid the prediction her diary made about herself. As she is able to control her worshippers, Tsubaki does not make use of any weaponry. When Yuki and Yuno travel in time to the next world their actions shape a future in which Tsubaki's parents never take their fatal car ride. This prevents the cult's transformation into an evil cult, and Tsubaki is spared from her horrible fate. She is named after Proserpina (Persephone) — roman goddess of Underworld. The characters of her name mean "Spring" (春), "Day" (æ—¥), "Field" (野), and "Camellia"(椿), respectively.
