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 December 2009, nine bound volumes have been released in Japan. The manga has been licensed by Tokyopop, and six of the English volumes have been released. A "pilot anime" DVD will be released with the 11th manga volume in September 2010.
Esuno has also authored two side-story manga, each one spanning five chapters: first Mirai Nikki: Mosaic which focuses on another Diary Holder and brings to light otherwise unrevealed plot points of the main story; and in 2009-2010, Mirai Nikki: Paradox (published in Young Ace), which tells the exploits of Aru Akise and Murumuru, filling the roles of Yukiteru and Yuno respectively, attempting to fix a timeline paradox created by Murumuru. Paradox is told in an alternate timeline which diverges from the main one at its beginning, and it may or may not eventually collapse into the main timeline.
Yukiteru always rejected any offers to go with friends and just keeps writing a diary on his cell phone. He has an what he believes is an imaginary friend called Deus Ex Machina. However, one day Deus asks him to play a survival game along with eleven others. The winner becomes the next Deus Ex Machina. In order to win, the contestants must use their diaries of the future to eliminate one another. For Yukiteru to survive, he must team up with another diary holder, a girl named Yuno.
Each player is assigned a number based on the order that Deus modified his or her diary. The diaries begin to record the future in the same manner their future selves would have written down events had they done so with some even being able to influence the beings whose future they divulge to the owner; the only exception to this rule is when the holder reaches a Dead End, a time when their lives would be finished without significant intervention. Each diary varies in its properties and functions depending on the owner's personality, occupation and lifestyle and they all their shortcomings. The diaries can be used without the owner's consent should they fall into another's hands. Since the diaries are written from the perspective of the owner's future self, the future can still be misinterpreted and thus the entries can become inaccurate. In addition to killing someone through normal means, if a diary is destroyed or broken, the owner also dies.

- Marco Ikusaba (戦場 マルコ Ikusaba Maruko ) and Ai Mikami (美神 愛 Mikami Ai ) were originally thought to be mere apprentices of the Eighth at first; Marco's apprentice diary predicted attacks before they happened, while Ai's located who ever she was looking for. In chapter twenty-eight they revealed themselves as together being the Seventh diary holder as well. The powers of their diaries, together known as the "Exchange" diary, are operated by two separate cellphones. It does appear their diaries are not affected by disruptions in the cell phone network as Akise's jamming plan only causes them to discard their Apprentice Diaries from the Eighth and use their own.
- The Seventh's own diaries, which they nicknamed the "Love Love Diary", tell the immediate future events of the other holder. The Seventh are a romantic couple and their respective diaries keep track of each other in much the same way Yuno's diary does with Yukiteru. This allows the Seventh diary holders to protect each other in times of danger. The pair do not seem to wish harm to those they are not in competition with, as they carry Hinata and Mao, who they had previously attacked, outside Kousaka's house so they are not harmed in the fire they start after that. They also render first aid for the knife wounds Ai inflicted.
- In chapter twenty-nine, they escaped having believed they defeated the newly reformed team of Yukiteru and Yuno, and have stolen the pair's diaries, as per the Eighth's orders. This allows them to gather information through both Diaries and hold an edge against the two Diary holders. In chapter thirty-two, Ai is killed due to blood loss by having her throat slit by Yuno. After the tower they are in is destroyed, Marco saves Yukiteru, Yuno and a near dead Ai. With his last act of his bond of "love", he gives Yukiteru and Yuno the last parachute and stays at the obliterated tower still holding onto a lifeless Ai.
