Plot: Amano Yukiteru (also known as “Yuki”) is a junior high school student who has difficulty making friends and prefers to be a spectator than get involved with anyone. He often writes down his daily experiences via his mobile phone in some form of a diary. Due to his life of solitude, he interacts with his imaginary friend whom he refers to as “Deux ex Machina”, the God of Time and Space, and Muru Muru, Deus’ Servant.
One day, Deus grants Yuki’s mobile phone the ability to pre-record what will happen in the future for the next 90 days. Brushing it off and treating it like a dream, Yuki proceeds to school only to realize that his mobile phone really is able to predict what is going to happen in the future. He later finds himself involved in a game that Deus Ex Machina established, denouncing the idea of being an imaginary friend.
In addition, he finds twelve other people who own their own future diaries in the form of mobile phones as participants of the game with only one rule: Kill each other before the world ends on the 90th day. The game ends when only one remains standing and will be rewarded the ability to stop the world’s destruction and become the successor of the God of Time and Space.
