The Future Diary

Yukiteru Amano is a loner who spends his time writing in his mobile diary and talking to an imaginary friend, Deus Ex Machina. However, one morning, he finds his diary entry for the day has been filled in already. Stranger yet, the events portrayed in the diary start coming true. Deus, who reveals he is an actual God, warns Yukiteru that if he loses his diary, he will die. As Yukiteru starts using the diary to his advantage, he is approached by a stalker named Yuno Gasai who also possesses a Future Diary that foretold his death at the hands of a serial killer, another Future Diary owner. Helping him evade the killer, Yuno helps Yukiteru throw a dart into the killer's phone, killing him. Afterwards, Deus explains the rules of the survival game to Yukiteru and the other diary owners, in which they must try to kill each other in order to win the right to succeed him.

Yuki is trying to figure out the reason behind Yunos Future Love Diary when a woman named Uryuu Minene interrupts him. She quickly identifies him as the 1st and announces that she is the 9th and that the 1st will die.

Having escaped with their lives from the 9ths death trap at the school Yuki and Yuno find them selves in an alliance with the 4th diary holder Detective Keigo Kurusu. The 4th asks the two of them to spend the day together at an amusement park to act as bait for the 9th who continues to elude the 4th and his detective diary. At the end of the day Yuki uncovers an unsettling secret about Yuno and the 9th may have fallen into a trap set by someone other than the 4th.

Yuki is unable to tell anyone about the corpses he saw in Yuno's house, fearing she will find out through her diary. The next day, Keigo, Yuki and Yuno visit the Sacred Eye cult, where Uryu is being held prisoner. The cult's leader, Tsubaki Kasugano, is the holder of the Clairvoyance Diary, a scroll which tells the future as seen by her followers and has foretold her death by the end of the day. Since Yuki has already evaded death twice, Tsubaki asks that he stay with her for the night in exchange for handing over Uryu, which he accepts, much to Yuno's resentment. At night, Tsubaki's followers fall under the mind control of Yomotsu Hirasaka, the diary holder who captured Uryu, and close in on Yuki, Yuno and Tsubaki. Yuno starts hacking at the followers with an axe and poses an ultimatum to Yuki: join her or die.

Yomotsu appears before the fleeing Yuki, Yuno and Tsubaki with four hypnotised cult members dressed like him. Yomotsu explains that his Righteous Diary led him to infiltrate the Sacred Eye cult and that he intends to blow himself and Tsubaki up using Uryu's bomb. Having learned from Keigo that Yomotsu is blind, Yuno manages to find and kill him. Tsubaki then has her followers capture Yuki and Yuno, revealing her plan was to kill them, Keigo and Yomotsu all along. Due to her traumatic past as a ritual rape victim, Tsubaki wishes to attain Deus' power in order to remake the world. Yuno manages to kill the guards holding her, cut off Tsubaki's hand and hand Yuki her diary before collapsing from exhaustion. Using both diaries, Yuki manages to avoid detection, until Tsubaki tries to lure him out by announcing that her followers will rape and kill Yuno. Realising Yuno's devotion to him, Yuki gathers his courage and manages to reach Yuno on time, but Tsubaki gloats that as long as he's in sight of her followers, his actions will be predicted in her diary. Yuki throws a small ball he found earlier up in the air, causing all of Tsubaki's followers to look at it and rendering her diary useless. Yuki then throws a dart at Tsubaki's diary, and since she is missing a hand, she is unable to deflect the shot. With her diary pierced, Tsubaki vanishes and Yuki and Yuno escape. Meanwhile, Uryu, who was released by Yomotsu, gets captured by Keigo, but he eventually lets her go in return for her contact information.

Knowing from her diary that Yuki's mother is coming home from abroad, Yuno breaks into Yuki's house with the intention of introducing herself to Yuki's mother. Despite Yuki's efforts, his mother and Yuno meet and take a liking to each other. That night, Yuno reveals to Yuki that her diary predicts they will "come together" on a certain date and tells him she will do anything to make sure that future comes to pass. The next day, Yuki's mother brings home Reisuke Houjou, a young boy whose parents were killed at the Sacred Eye incident. Despite his young age and precocious demeanor, Reisuke is a Future Diary owner, plotting Yuno's death.
