Future Diary: The Complete Series + OVA Blu-ray follows 14-year-old Yukiteru Amano, who is thrown into the Diary Game by the God of Space Deus Ex Machina! The only problem is 11 other diary holders are also trying to survive and become the heir to the universe!

Yukiteru is an introvert who quietly observes life and jots down mundane events on his cell phone. Suddenly, new entries that he didn’t write appeared. It turns out that his cell is a Future Diary, a device that predicts the future!

Knowing the future is excellent except for one catch—Yukiteru and eleven others are part of a survival game. The goal of the game? Eliminate the other diary holders.

Yukiteru will find that his classmate Yuno Gasai will be by his side and protecting him from the other contestants! The only catch is that she is a charming psychopathic classmate who stalks him after making a promise to go stargazing together!

Who will be the next heir to Deus in the Diary Games? Will Yukiteru Amano survive alongside Yuno Gasai, or will they find that the game is more than they can handle?
