Yuki becomes involved in the Diary Game when to his shock Deus, a god-like being whom he thought was an imaginary friend, turns out to be real and selects him as one of twelve contestants in a 90 day battle royale where the contestants must kill each other using their special diaries; the last survivor becomes Deus' new heir. Yuki's diary is called the Random Diary, which written from his point of view, gives a detail explanation of his surroundings very accurately, whether it be the present or the future. Yuno Gasai is his only ally and his stalker.
