|Future Diary (未来日記 Mirai Nikki?) is a Japanese manga series written and illustrated by Japanese manga author Sakae Esuno. The manga was first serialized in the Japanese shōnen manga magazine Shōnen Ace on January 26, 2006, and is published by Kadokawa Shoten. As of April 26, 2011, eleven tankōbon volumes have been released in Japan. The manga has been licensed by Tokyopop, and ten of the English volumes have been released, with a release for the last two now uncertain due to Tokyopop ceasing publishing in North America. A “pilot anime” DVD was released with the 11th manga volume in December 2010. A TV anime series animated by Asread began airing in Japan on October 10, 2011. Funimation has licensed the anime for distribution in North America.
Esuno has also authored two side-story manga, each one spanning five chapters: first Future Diary: Mosaic which focuses on another Diary Holder, Minene Uryu, and tells unrevealed plot points of the main story; and in 2009-2010, Future Diary: Paradox (published in Young Ace), which tells the exploits of Aru Akise and Murumuru set in an alternate timeline.
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. One day, Deus gives Yuki a special diary, mentioning something about a game. Yuki pays it no mind until he discovers that his new diary has entries in it spanning the next 90 days–entries about the future that come true with unnerving accuracy. Deus, the not-so-imaginary God of Time and Space, then forces Yuki to participate in a battle royal with eleven other people, each of whom also have a diary that can predict the future in some unique way. The rules of this “Diary Game” are simple: before the world ends on day 90, the contestants must to find and kill all the other contestants, and the last one standing will become the new God of Time and Space.
