Yukiteru "Yuki" Amano is a loner who spends most of his time writing a
diary on his cell phone or talking with his imaginary friends Deus Ex
Machina, the God of Time and Space; and Murmur, Deus' servant. One day,
Deus gives Yuki a special diary, mentioning something about a game.
Strangely, Yuki's new diary has entries in it spanning the next 90
days—entries about the future that come unnervingly true. Deus, the
not-so-imaginary God of Time and Space, then forces Yuki to participate
in a battle royale
with eleven other people, each of whom also has a diary that can
predict the future in some unique way. The rules of this "Diary Game"
are simple: the contestants must try to find and kill all the other
contestants before the world ends on Day 90, and only the last one
standing can prevent the Apocalypse and become the new God of Time and Space.
