Folklore detective Asou Daisuke would rather deal with normal, everyday, things like cheating spouses, embezzling partners and the like. (That and his huge collection of ero-manga.) Because whenever he deals with the supernatural, he gets the hiccups.

But no matter, an endless stream of desperate people come to him troubled by what he calls allegories. Those are stories, usually urban legends, that one believes to be true and if one believes strong enough can cause them to become true. His first case involves "The Man Under The Bed." Can he stop this creepy man with an axe before he chops up kawaii Hiranuma Kanae? Why does Asou count his hiccups, and just who is that strange girl in his bathroom?

Yukiteru "Yuki" Amano is a loner who never really interacts with people and prefers writing a diary on his cell phone with his imaginary friends Deus Ex Machina, the God of Time and Space, and Muru Muru, Deus's servant.
However, Yuki soon learns that Deus is real when he makes Yuki participate in a battle royal with eleven other people. Within this "Diary Game," the contestants are given special diaries that can predict the future, with each diary having unique features that gives them both advantages and disadvantages.
The rules of the game are simple: the contestants have 90 days to find and kill all the other contestants, and the last one standing will become the new God of Time and Space

In a parallel world where the strongest of the non-diary holders "Akise Aru" takes the place of Yukiteru ( The protagonist from Mirai Nikki ) for a few days, what will happen?

Find out more about the other characters from Mirai Nikki - Future Diary. These stories start out a few days prior to them receiving their own diary and give us some insight as to how they think and their personal reasons for using the diary they've been chosen to have. In the process learn a little more about Deus ex Macchina, the 'God' of Space and Time, and what his goal really is.

Ten years ago, a child wished for the destruction of the world. Now, a group of people has the ability to grant their wishes depending on their power. They are called "Order User."

Before these great people who have the power of "Order," one person excels the most with the ability to rule and conquer the world and turn people into puppets when it is in his jurisdiction. This power belongs to Hoshimiya Eiji, who is also responsible for the destructive phenomena that happened exactly ten years ago.
