OVA
Description
Yukiteru Amano starts as a reclusive 14-year-old, observing life from the sidelines and compulsively recording events on his cell phone. His parents' divorce deepens this isolation, leaving him detached socially until imaginary companions manifest as actual entities.
Deus Ex Machina, god of time and space, transforms Yukiteru's mundane diary into the "Observance Diary" or "Random Diary," which predicts future events near him at fixed intervals. Crucially, this diary cannot show information directly impacting Yukiteru himself. He is forcibly enrolled in a survival game with eleven other participants wielding similar future-predictive diaries, where the winner will succeed Deus.
Initially defined by profound timidity and conflict avoidance, Yukiteru becomes heavily dependent on Yuno Gasai, a classmate and fellow diary holder obsessed with him. Her "Yukiteru Diary" tracks only his actions, forming a complementary pairing that counterbalances each diary's inherent weaknesses when used together. Though terrified by Yuno's volatility, he repeatedly forgives her violent acts and attempts to temper her behavior.
A turning point arrives after witnessing both parents' murders. His motivation shifts from mere survival to determined engagement in the game, aiming to resurrect his family upon becoming god. This trauma plunges him into ruthlessness, evident when he refuses to prevent allies' deaths and deliberately kills friends Hinata, Mao, and Kosaka after they dispute Yuno's claim that resurrection is possible.
His relationship with Yuno evolves amidst revelations about her origins. Muru Muru exposes that the current Yuno originated from a separate timeline (First World), where she previously won the survival game, became god, and discovered resurrection impossible. Consumed by grief, she traveled back in time, murdered her alternate self in the Second World, and inserted herself into Yukiteru's life. Learning this shatters his trust, yet he maintains their alliance.
At the game's climax, Yukiteru rejects their pact to kill each other for godhood. He pursues Yuno into a third timeline, protecting that world's younger incarnation to secure her a peaceful upbringing. Confronted by the original Yuno, he declares his love and offers his life, but she chooses suicide instead. Yukiteru ascends as the new God of Time and Space.
As deity of the Second World, he isolates his realm from external forces and sustains the third world's Deus to prevent collapse. He mourns Yuno for 10,000 years until the third world's Yuno, implanted with her First World counterpart's memories by Muru Muru, breaches dimensional barriers. They reunite as gods of their respective worlds.
Beyond his diary, Yukiteru wields throwing darts with skill, a pre-game hobby adapted for combat. Post-ascension, his divine powers grant dominion over space, time, causality, and reality, though specifics remain largely undefined.
An alternate timeline in *Future Diary: Paradox* depicts Yukiteru forming a romantic relationship with Aru Akise, an artificial human investigator, exploring dynamics diverging from the primary timeline's events.
