Yukiteru Amano

Yukiteru was an introverted teenager living in Sakurami City until he was given a "Future Diary" by a being known as "Deus Ex Machina", a being claiming to be God. The "Future Diary" predicts some aspect of the holder's future, in the case of Amano's, the actions of those around him, but never predictions directly concerning himself. The diary, which takes the form of a cell phone, marks Yuki as a combatant of a battle royale to the death between twelve "diary holders", with the winner becoming Deus' successor as god. Yuki's intends to revive his dead parents if he wins the battle and becomes a god. Amano is aided in the battle, not always willingly, by Yuno Gasai, a violent, stalker-like "diary holder" who happens to be obsessed with him.
