Protagonists

Yukiteru Amano

is the main male protagonist of the series and the First Diary user. Also known as Yuki, he is a reclusive and shy 14-year-old middle school student, opting to be a bystander to incidents around him to write about them in a diary on his cell phone instead. He becomes involved as one of 12 contestants in a 90-day battle royale when, to his shock, his imaginary friend Deus turned out to be a real God of Space-Time, planning to have the sole survivor of the game succeed his throne. Yuki's ordinary diary becomes the Random Diary, a diary capable of predicting future events happening around him from his point of view. While versatile in any situation, the diary does not state what happens to Yuki himself, and since it is written from his point of view, the entries may not always be accurate.
Unlike most of the contestants, Yuki wishes for a simple, peaceful life. Because Deus considers him a personal favourite to win, he is mainly targeted by other Diary users. Knowing he is weak, cowardly and naïve, he quickly makes friends and allies. One of these is Yuno Gasai, an obsessive stalker who is madly in love with him and will kill to protect both of them. His goal is to not kill anyone; however this outlook has changed when his divorced parents are killed because of the game and Yuno convinces him that becoming the God of Space-Time can bring them back, becoming a ruthless and dishonest player.
Eventually he learns of Yuno's true origins and intentions, finally stepping out of his role as a constant bystander to intervene in changing her future, including those of the other Diary owners that led terrible, unfortunate lives. When trapped by her in an illusionary utopia, he breaks free through his love and force of will to meet her again. A touched Yuno commits suicide to let him win the game. A distraught Yuki refuses to use his godly powers for 10,000 years, until the Third World Yuno returns to him with memories and love of the First World Yuno. as they become the gods of the third world, succeeding Deus without another death game involved.
He is named after Jupiter, the Roman god of the sky, weather and lightning.

Yuno Gasai

is the main female protagonist of the series and the Second Diary Holder. While a perfect model student on the surface, she is actually a psychopathic yandere who is obsessed with Yukiteru Amano, whom she affectionately calls "Yuki", and kills unhesitatingly to protect him. Her Future Diary is the Yukiteru Diary, a stalker diary that gives her explicit details on whatever Yuki is doing in the present 10 minutes. By working together with his Random Diary, they are able to solve their diaries' weaknesses.
Yuno is named after Juno, the ancient Roman goddess of love and marriage.

Minene Uryū

is the secondary female protagonist, the Ninth Diary user and the protagonist of the side-story manga, Future Diary: Mosaic. An infamous atheist terrorist, Minene is a young woman who has hatred against organized religion, particularly on any belief towards God. Her hatred of religion stems from her past when she and parents were traveling in a city in the Middle East but got caught in a battle which is hinted between the Israelis and Palestinians, where her parents were killed in the crossfire. Blaming God for her parents death, she leads a crusade of destruction against those associated with God. Minene got involved in the Diary game when after a failed assassination to kill a Catholic Cardinal, where as she tried to flee, she almost fell to her death but was saved by Deus who gave her an offer to save her if she join his game. Minene's diary is the Escape Diary, which will chart out the best course of actions for her to escape whenever she finds herself in a dangerous situation. While it means she can escape anything, it is not perfect as the diary can only tell her how to escape if there are favorably conditions that allow her any chance to escape.
Originally, she wants to win the game to destroy religion worldwide but later change her mind after befriending Yuki and his friends. While she began as an antagonist against Yuki, she later became his ally, becoming a big sister figure to him and both of them hold no animosity with each other despite Minene being responsible for the destruction and deaths at his school and Yuki blinding her left eye. She shares an interesting relationship with Masumi Nishijima of the police whom she met during her failed assassination of the cardinal. While she constantly dismisses all of his attempts to get to know her, she finally relent and falls in love with Nishijima.
Together with Nishijima and Yuki's friends, they invade the twin tower buildings, to kill the Eleventh. Yuki appeared only after Nishijima's death and Minene realized that Yuki was just using them as a shield when Yuki told her that he and Yuno had been following them but did not help out and let Nishijima die. Wanting to avenge Nishijima's death, Minene has a gun fight with Yuki. Despite having the advantage, she is unable to kill him as Yuki reminds her of her younger self, allowing Yuki to shoot her. Knowing that she does not have much time to live, she decides to help Yuki by blowing herself up to open the bank vault where the Eleventh is hiding in.
She fails to blow up the vault, but survives the blast, and revealed before they invade the twin tower buildings, Deus transferred his knowledge and half of his power to her, thus preventing her death. Minene rescues Yuki and travels with him to the Third World to stop Yuno from killing her other self. She also contacts Keigo Kurusu and warns him of his son's fatal heart disease, altering the future. Minene survives the final battle, and is shown to be living happily with the Third World Nishijima while having children who have inherited her godly powers and can fly, though she still stayed in contact with Deus and Murumuru.
She is named after the Roman goddess Minerva.

Aru Akise

is the secondary male protagonist and the protagonist of the side-story manga, Future Diary: Paradox. One of Yuki's new friends at his new school, Aru is a genius with amazing investigation skills and wants to be a great detective. He becomes involved in the Diary Game to learn the mysteries surrounding it and protect Yuki. Aru has feelings for Yuki that are beyond that of friendship, which angers Yuno. As the games continue, Aru becomes suspicious of Yuno and tries to find out what secrets is she hiding from Yuki. He soon discovers Yuno's origins but also his own when he learns about his creation by Deus as an "observer" to keep on eye on the contestant. He receives the Detective Diary from the Eighth Diary user which can make predictions based on the predictions of the other diaries. It is nearly a perfect diary, except when accounting for Aru's feelings towards Yuki, meaning he can act against what would be a perfect outcome. It also cannot detect the difference between diaries from other universes, which Yuno exploits to defeat him. Despite losing to Yuno, he continues to help Yuki and gives him the clue on Yuno's identity before she decapitates him. In the Third World, Aru is seen alive and continues as Deus' observer, with Reisuke as his detective-in-training.
Aru is the protagonist of Paradox, set in an alternate timeline after Murumuru accidentally kills Yuno and Yuki is mortally wounded by Takao Hiyama. Aru and Murumuru take their respective places as First and Second until Murumuru's alterations have been fixed. However, as the game progresses, Aru sees the horrors of it and decides to save everyone to stop the game. Altering the events of the incident with Tsubaki Kasugano, Aru is able to make allies with a majority of the diary owners. However, his attempt to stop Murumuru from erasing the timeline fails when he stumbles across Yuno and how she killed her Second World counterpart, before being cast back to the start of the survival game.
He has many parallels with Bacchus, including being created from a god and gaining supernatural insight later in life.

Diary Game contestants and judges

Diary Holders

Takao Hiyama

, the Third Diary user, is Yuki's school teacher who is secretly a serial killer who wears a heavy bulletproof trenchcoat with a hat and mask that hides his identity. Takao's diary is the Murder Diary which gives him details on who his next victims are and where and how he kills them. While the diary helps him locate his victims and prevent them from escaping, it does not tell him what to do if his victims will fight back; thus, he can be easily defeated. Takao figured out that Yuki holds a diary as well since Yuki used his diary to improve his grades. Takao heads to Yuki's apartment to kill him, but Yuno shows up and takes him to the roof. Yuno uses her phone as a surveillance camera so Yuki can see where Takao is through his own phone while sitting on the roof's ledge. Yuno runs out of the corner to surprise and distract Takao, while Yuki pops up to attack him. He was killed when Yukiteru pierced his diary with a dart.
It is revealed by Murumuru that Takao repeatedly accidentally killed himself when she was presenting him with his Future Diary. First was when he thought she was a witness to his recent killing and sliced the phone, and then thinking the phone was evidence, he destroyed it again. She admitted she suspected he would be the first to go because of his paranoid personality.
In the alternate universe, he is captured by Yomotsu Hirasaka, and put in prison in the anime.
His surname, Hiyama comes from the Roman god Vulcan.
