Mirai Nikki (literally Future Diary) is a dark manga about the asocial Yukiteru Amano, who obsessively keeps journals. One day, he finds that his imaginary friend Deus Ex Machina, the lord of time and space, has made his cell phone diary able to predict the future.

Yukiteru Amano kept a diary he wrote in each day. He was always the bystander.

Yukiteru Amano (or Yuki) is a loner who never really interact with people and prefers writing a diary on his cell phone with his only companion being an imaginary friend named Deus Ex Machina, the God of Time and Space. However, Yuki soon learns that Deus is not a figment of his imagination but real when Deus makes him a participant in a battle royale with eleven others.

The story revolves around a supernatural system where, anyone with a powerful grudge may summon the Hell Girl, a mysterious entity that will exact her client’s revenge with the price of damning their own souls to hell after they die. After torturing the cursed target by letting him/her relive inside her/his own cruelty and injustice, Hell Girl ferries the poor soul into Hell, where eternal pain and suffering awaits them.
