Arata Hoshino is a 21-year-old college student who has little interest in his future. His friend Rui Moriguchi gives him a limited Chronus Seed Corporation cell phone to use after their friend Kosaka steps on Arata's phone. Arata discovers the next day that his phone has developed an unusual ability to predict his future and exploits it by cheating in an exam and spending a night clubbing with friends. However, soon learns he is not the only Future Diary owner around - he meets Yuno Furusaki, a 19-year old who is Arata's stalker and is madly in love with him. Arata quickly discovers the pair of them are in a survival game formulated by an unknown being named Deus where the diary owners must eliminate one another to win a "wonderful future". Other members include policeman Kinjiro Hagito, teenage student Megumi Fuwa, serial killer Yousuke Okuda, and Tohru Kibe, CEO of Chronus Seed Corporation. Arata's father Kurou Hoshino, an employee at Chronus, is revealed to have a diary himself and sacrifices himself to protect Arata from Yousuke and dies, his body disappearing afterward.
Rui and his sister Haruna Okie offer to help Arata end the survival game, with Kinjiro, who is their cousin, also forming an alliance with them. Rui gets Megumi involved, but that night, she and Arata are captured and locked in a warehouse with Yuno by an unknown assailant. Megumi, who is emotionally unstable after a long line of being backstabbed by friends, turns against Arata, who is forced to break her diary and eliminate her from the game.
