The Future Diary

Shocked at Deus' answer, Aru attempts to tell Yuki, but Deus stops him. Deus reveals that Aru is an entity created by him to observe and record information on the survival game and starts disassembling him, promising to spare him if he proves he has done anything out of his own free will. Aru succeeds when he reveals he had Kamado make his diary into an apprentice diary, wishing to change the future and save Yuki. As Yuki and Yuno arrive at Aru's apartment to kill Kamado, they're held off by Aru. Yuno starts fighting Aru, while Yuki chases after Kamado and his friends. When he runs into Hinata, she tells him what Aru learned from Deus: even the divine power bestowed to the winner of the survival game cannot bring the souls of the dead back. Meanwhile, Yuno, who has been cornered by Akise, stabs herself and calls Yuki, tricking him into thinking everyone is deceiving him. Yuki kills Hinata, Mao and Kousaka, believing he can bring them back to life later. Aru reaches Yuki and warns him that Yuno plans to kill him. Yuno catches up to Aru and they fight again. Although Aru breaks Yuno's diary, she doesn't vanish; she produces a second cell phone from her pocket, claiming the first one was a fake, and slashes at Aru's throat. As Yuno kills Kamado, a dying Aru, who knows the diary he destroyed was real, suddenly has an epiphany about Yuno. Since he can no longer talk, he writes a message in his phone and shows it to Yuki, allowing Yuno to finish him off as Deus collapses.

Yuki and Yuno wreak havoc, demanding that Balks release their friends and commit suicide. Balks locks himself in a vault belonging to Yuno's parents' bank, which can only be unlocked by himself, Yuno's parents, and the real Yuno. Uryu, reasoning that Yuki can no longer eliminate Balks for her, starts hunting him. As she does, she tells him how she lost her parents in the Middle East as a child and grew up under the constant threat of death. At the same time, Yuno frees Yuki's friends and goes to kill Kamado, but she is stopped by Aru. In a tense showdown between Uryu and Yuki, the former sees her innocent child self in the latter and lets him shoot her. Uryu then destroys her diary voluntarily in order to detonate a bomb triggered by her death, intending to destroy the vault door for Yuki. However, the door withstands the blast. Yuno arrives, sends Yuki away to destroy HOLON, and somehow manages to open the vault door and kill Balks. A few days later, dark vortices appear all over the city. In Deus' realm, Murmur is panicking over the world ending sooner than expected, when Kamado appears with Aru, who asks Deus if it is really possible for his successor to return the world to the way it was.

Despite Aru's revelation, Yuki declares his trust in Yuno. Balks connects Kamado's server to HOLON, a supercomputer which holds user accounts of every citizen of the city, making them his apprentices. Uryu tries to attack Balks, but his diary lets him turn the tables. Nishijima, who's fallen in love with Uryu, comes to her aid and destroys the supercomputer. However, it turns out to be only one part of the whole, and Balks' plan is put into motion. As Aru sends Hinata, Mao and Kousaka to help Uryu and Nishijima destroy the remaining parts of HOLON, Uryu figures out Balks' diary can read the predictions of all other Future Diaries. Deus reveals to Uryu that Balks helped him design the Future Diaries, wishing to grant divine power to the human race. Uryu, Nishijima, Hinata, Mao and Kousaka storm HOLON's location, overwriting their diaries' predictions to confuse Balks. In response, Balks makes use of his secretary's diary and manages to capture Hinata, Mao and Kousaka, as well as injure Uryu and kill Nishijima. Uryu is saved by Yuki and Yuno, who've used her as bait to get to Balks.

The mayor of the city, John Balks, passes a motion to have Kamado's orphanage shut down. He then attends Deus' meeting, where Yuki and Yuno, having deduced his identity, expose him as the Eleventh diary holder. Uryu relays these news to Nishijima, who reveals he's been reassigned as Balks' bodyguard. Furthermore, he's discovered that Yuno was adopted. Yuno theorises that Balks wants to seize Kamado's Future Diary server, so she has Yuki form an alliance with her. Yuki, Yuno, Kamado and her apprentices ambush Balks' car on a country road, but he uses a jammer to sever connections to Kamado's server. Yuki and Yuno, who anticipated this, betray Kamado and slaughter her defenseless apprentices. Kamado flees in Balks' car, while Yuki and Yuno give chase. As Yuki and Yuno corner Balks and Kamado, Uryu appears with Aru. Aru reveals he's retrieved Yuno's umbilical cord from her orphanage and that its DNA matches the third corpse's, meaning that the real Yuno Gasai is dead and the one Yuki has known all along is actually an imposter.

In a flashback, Yuno is revealed to have murdered her parents, who used to discipline her harshly for failing to meet their standards. After she fell in love with Yuki, he became her sole reason to live. Yuki asks Deus to bring his mother back to life, but he reveals that he is dying and his powers have faded. Furthermore, unless a successor is determined soon, all existence will collapse. When Yuki's father returns home, Yuki, who knows he killed his mother from his diary, demands that he turn himself in. However, his father points out that he has no evidence. The next day, Yuki goes after his father, expecting him to lead him to evidence. However, it turns out that Yuki's father wanted to visit the site where his family was going to go stargazing before he turned himself in. As Yuki reconciles with his father, they are ambushed by agents of Eleventh and Yuki's father is murdered. Enraged, Yuki fights back and manages, with Yuno's help, to kill the attackers. Afterwards, Yuki declares that he is now determined to win the survival game in order to attain the power to resurrect his parents. When he tells Yuno this means he has to kill her, she calmly replies that she is ready to die for him at any time.

In a flashback, Marco and Ai are abandoned children who meet in the commercial tower, grow up in Kamado's orphanage and eventually fall in love. Yuki chooses to take Yuno's hand, while Marco and Ai run to the crumbling tower's roof with Yuki's father, intending to jump off with parachutes. Yuno catches up to them and once again tries to fight them alone, while Yuki hides and attempts to help her with his diary's predictions. Yuno loses and has her phone taken away, but it turns out to be Marco and Ai's decoy, which distracts them with false predictions. As a result, Yuno manages to critically injure Ai. Yuki's father grabs one of the two parachutes and escapes the tower, but he runs into Yuki's mother, who has been informed of the situation by Nishijima. When she threatens to turn him in, he stabs her. Yuki, Yuno and a dying Ai are trapped in the wreckage, but Marco attempts to free Ai despite having been mortally wounded himself. With Yuki and Yuno's help, the debris is cleared out and Marco and Ai die together as the tower collapses. Yuki and Yuno escape using the second parachute, only to find Yuki's mother has died. Meanwhile, Nishijima has been unable to find Kamado's Future Diary server.

Aru deduces that Marco and Ai have not destroyed Yuki and Yuno's diaries because they want to take advantage of the information they provide. In order to confuse them, he has Uryu feed Yuki false information. Yuki's father visits him in the hospital, but while Yuki's away, he searches the room for his cell phone. Yuno overhears that he has promised to destroy it in return for the cancellation of his substantial debt and realises he is being used by the Eleventh diary holder. Marco, who's learned all about the situation from Yuki's diary, considers Yuki's father a useful link to Uryu and the Eleventh and calls Yuno, demanding that they bring Yuki's father to an abandoned commercial tower. Once they arrive, Marco places Yuki and Yuno's phones on a table and attacks Yuki's father. As Yuki futilely fights Marco, his father goes over to the table and breaks his phone. However, nothing happens. Yuno, who's realised that the phones were decoys, attacks Ai and successfully retrieves both diaries. Just then, Marco and Ai's apprentice friend sets off explosives. The floor under Yuki collapses and both his father and Yuno reach out to grab him. Meanwhile, Nishijima has uncovered the identity of Eighth, a children's caretaker called Kamado Ueshita, and goes to search her orphanage.

Aru deduces that the Eighth's diary is a server hosting and sending predictions to the blogs of her apprentices. When Yuki's diary predicts an attack by three of them, Aru has him moved to Kousaka's mansion. His plan is to lure the apprentices in, then deactivate the area's cell phone tower, severing their connection to the Eighth's server. Once the attack begins, however, Yuno appears and cuts the power to the tower remote control, wanting to defend Yuki by herself. Aru and Kousaka rush to deactivate the tower manually, while Yuki keeps Yuno in restraints. Two of Eighth's apprentices, Marco Ikusaba and Ai Mikami, manage to corner Yuki and Yuno by the time Aru deactivates the tower. However, Marco and Ai reveal that they are also the "owner" of a bona fide Future Diary, which has remained unaffected. With no other choice, Yuki releases Yuno, who intimidates the couple into retreating. When the third apprentice sets the mansion on fire, however, Marco and Ai counterattack. Their diaries' ability to predict each other's actions manages to overwhelm Yuno, resulting in her and Yuki getting injured and their diaries taken away. As Yuki and his friends are brooding in the hospital, they are approached by Uryu.

Aru talks to Yuno through her surveillance feed, revealing he dug up three corpses from her garden, two of which had recently had their skulls removed. When he threatens to give this information to the police unless she releases them, the stress causes Yuno to alter her memory again, rendering negotiations moot. As Kousaka uses his cell phone to post his will in his blog, it is apparently turned into a Future Diary by the Eighth diary holder, who adresses him as an "apprentice". On Aru's advice, Kousaka acts out his diary's predictions, reaching an amnesiac Yuno, a catatonic Yuki and a bound Hinata in the control room. His appearance causes Yuki to recover, recalling how Yuno abducted him to keep him safe until July 28th. Yuno places the key to Yuki's shackles on the floor and tosses Kousaka the control panel key, allowing him to free Aru and Mao. Yuno then takes advantage of Kousaka's distraction and shoots at him with a crossbow. However, Yuki, having had his key kicked over to him by Hinata, frees himself and stops Yuno, leaving her behind when his diary predicts the imminent arrival of three diary holders, all apprentices of the Eighth.

When Deus realises that his assistant, Murmur, manipulated events to hasten Keigo's elimination, she claims she wants the game concluded before he has to "retire" and challenges him to a wager on the winner of the survival game, with her picking Yuno and Deus betting on Yuki. Yuki and Yuno go on a stargazing trip, but Yuno alters their destination along the way. Worried about Yuki's safety, Aru contacts Nishijima and they manage to narrow Yuki and Yuno's location down to a run-down holiday resort, enlisting Hinata, Mao and Kousaka to search for them. As they split up and search the abandoned hotels, Aru and Kousaka face various traps set by Yuno, while Hinata is tricked by a text message Yuno sent from Yuki's phone. When the others attempt to find Hinata, they get locked in a room which starts to fill up with gas. At the end of the episode, Yuki is shown bound to a chair, with an ecstatic Yuno sitting between two skulls.

While the police surrounds the hospital, Uryu takes Keigo's wife and son hostage and tries to bargain with him. However, Keigo is convinced the only way to save his family is to win the survival game and refuses to negotiate. Yuki gets captured by the police, but as Keigo takes hold of him, Yuno appears, holding a grenade. Even when Keigo agrees to let Yuki go, Yuno decides to detonate the grenade, reasoning she'd rather die taking out Keigo than not be with Yuki. The grenade turns out to be a flash bang, knocking everyone out. Meanwhile, Uryu tries to escape the hospital, only to run into Nishijima. She tells him about the deal she and Keigo made and how he framed Yuki and Yuno, and they both rush back to the hospital. Yuki regains consciousness and tries to shoot at Keigo, but he uses Yuno as a shield. Despite his diary predicting he will kill Yuno if he shoots, Yuki refuses to give up, proclaiming his love for her. The future somehow changes and Yuki gets a clean shot at Keigo. Uryu arrives with Nishijima, who places Keigo under arrest. Since he's no longer a detective, his Investigation diary stops predicting the future. After learning his family has been rescued, Keigo asks Uryu to take care of his son, apologises to Yuki and breaks his own diary, removing himself from existence. Yuki and Yuno are exonerated thanks to files Keigo left behind, while Uryu escapes yet again. A few days later, Aru sends Yuki a text message warning him about Yuno, but she intercepts and deletes it.

In a flashback, Keigo forms an alliance with Uryu, promising to stop pursuing her and asking her to take care of his terminally ill son if he is eliminated from the Survival Game. Yuki and Yuno get arrested and brought to Keigo. In the interrogation room, Keigo forces Yuki to play a rigged game of Russian Roulette with his service revolver. Alerted to Keigo's treachery by her diary, Yuno knocks out the detectives guarding her and steals their guns. Just before Yuki gets shot, Yuno breaks into the room, injures Keigo and leaves with Yuki. Panicking, Yuki shoots at one of the policemen pursuing them. Since both Yuki and Yuno have now committed a crime, their actions can be detected by Keigo's diary, which was his plan all along. Trapped at the police station's roof, Yuki and Yuno jump off, but a truck's tarp breaks their fall. The next day, Yuki and Yuno are hiding from the police when they notice Keigo's wife visiting a hospital. When they follow her, they get ambushed by Uryu, who blows part of the floor up. After Yuki accidentally causes more of the floor to collapse, Uryu allies with Yuki in order to have Yuno pull them both to safety, incurring Keigo's wrath in the process. With their deaths foretold in all three diaries, Uryu takes Yuki and Yuno to the room where Keigo's son and wife are.

While making bombs for Keigo, Uryu remembers the time she was captured by a detective called Nishijima while confronting the serial killer diary holder. Although they develop a rapport as they evade and defeat the killer, Uryu ends up knocking Nishijima out to escape. Aru sets up Yuki and Yuno on a date to a bridal fair, where they meet Keigo's wife, while he investigates Yuno's house. When Yuki and Yuno return, they find Aru at the door of the room with the corpses. However, the wall has been demolished and the corpses buried in a deep hole in Yuno's garden. Even though this is Yuno's doing, she has no recollection of the event, nor of Yuki visiting her house before. Aru theorises that Yuno's mental balance is so fragile that she modified her own memories as a defense mechanism. Meanwhile, Keigo frames Yuki and Yuno as suspects for his murder of Hinata's father.

In a flashback, Hinata receives the Breeder Diary from her dog breeder father, who wants her to eliminate Aru. When Hinata demands Aru's diary, he challenges her to guess which hand he's hiding a coin in, with his diary as the forfeit. Despite using Yuki's diary, Hinata loses and has to release Yuki. Yuno, however, realizes that Aru is not a Future Diary owner, relying on bluff and observation instead. Unfazed, Aru proposes one more round of his game, with Yuki's diary on the line. By intending to tell Yuki that he lost, no matter what the outcome, Aru manages to neutralize Yuki's diary, since its predictions are based on Yuki's perception. With the game thus reduced to a 50/50 gamble, Aru manages to guess correctly. Mao attempts to destroy Yuki's diary, but Yuno injures her. Yuki, Yuno, Aru and Kousaka leave the park, while Hinata uses her diary to send the dog pack after them. Yuki decides to return to Hinata and try to reason with her, but Yuno reaches her first and threatens to kill her, as well as anyone who attempts to come between her and Yuki. To pacify Yuno, Yuki is forced to declare her his girlfriend. Hinata's father communicates with everyone via radio, explaining that he mistook Aru for a diary owner and warning Yuki about Keigo before being killed by him.
