John Bacchus

John Balks is the Eleventh diary owner, and the final owner introduced in the series. The Mayor of Sakurami City, John Balks is actually the creator of the Future Diaries technology and suggested the survival game to Deus Ex Machina. He fused the first Future Diaries together to create his "Watcher Diary".

Personality
Balks is a middle-aged spectacled gentleman dressed in fine clothes and wears a hat resembling a Jewish kippah. Using his position as mayor of Sakurami City, Balks is the most powerful man in the city and his influence is very strong. In his opening scene, Balks convinces the entire city council to agree to shut down Kamado Ueshita's orphanage by crying crocodile tears and blubbering about how he adores every child in the city as if they were his own. Balks is obviously intelligent and manipulative, but can be just as honest.

He is very polite and acts like a gentleman towards Kamado. However, he is perhaps one of the more ruthless of the twelve diary owners, being strategic and using his intelligence to make any situation's outcome be to his advantage. His goal in the game is to help humanity evolve to a higher form of being, having similar beliefs like the Macedonians, Romans and Nazi Germany. His diary, the "Watcher Diary", has an ability to read the other Future Diaries' entries, and the Apprentice Diaries. It is probably the most powerful of the twelve Future Diaries, on par with Yukiteru Amano's Random Diary. However, the diary is vulnerable when misinformation is put on the diaries that Balks is reading, although he can counter this weakness by figuring out the true details of the diaries.

Backstory
Balks, wishing to evolve humanity to new heights, met and approached Deus with the proposal to give mankind some of his divine power. His concept was the Future Diaries, which could predict the future. Learning of Deus' approaching demise, Balks' idea would contribute to the survival game Deus had in mind to choose a successor. Deus used his powers to help create the powers of the Future Diaries, whilst Balks developed the actual technology. The two made several archetypal prototypes to test out the powers of the diaries - The "Radar" Diary, which could predict a person's surroundings; the "Searcher Diary" which predicts the actions of certain individuals; the "Organizer" Diary which predicts the actions of groups; and the "Supplier" which gives others the power to predict the future.

Balks formed a fifth prototype, the "Watcher" Diary, in order to watch and record the activities of all other diaries. This effectively made Balks the first Future Diary owner, despite being titled as Eleventh in the survival game.

Enter Eleventh
Balks debuted with the other diary owners during Deus' first meeting of the survival game, targeting Yukiteru Amano as the primary target to eliminate after he killed the Third owner Takao Hiyama. He is present at the second meeting, and other subsequent ones, although he does not make a move in the game until later on, likely observing the other owners until half of them are eliminated.
