The Future Diary opens with a boy who would rather watch than speak. Yukiteru Amano, antisocial and alone, gets pulled into a death match against 11 other mentally scarred individuals. Each of the 12 players carries a prophetic device tuned to their personality, giving them control over their future and the fate of their foes. The series ran for one season and 26 episodes on Chiba TV, from October 9, 2011 to April 15, 2012.
That premise is the whole engine. Twelve damaged people, twelve phones that tell them what comes next, and a rule set that turns every friendship into a target. The show does not waste the idea.

Yukiteru Amano and the Phone That Talks Back
Yukiteru is voiced by Misuzu Togashi. He is not a hero in the usual sense. He is a bystander who gets drafted, and the series keeps him off balance for most of its run. His device is a diary, and the diary is not neutral. It reflects who he is, which means his survival depends on a version of himself he does not like.
The supporting cast is large and mostly grim. Tomosa Murata voices Yuno Gasai, the character the show is remembered for. Minoru Shiraishi plays Oji Kosaka. Akira Ishida plays Aru Akise. Masahiko Tanaka is Keigo Kurusu, Takaya Hashi is John Balks, and Mai Aizawa is Minene Uryu.
Further down the roster: Yuki Matsuoka as Hinata Hino, Natsuko Kuwatani as Ai Mikami, Eri Sendai as Tsubaki Kasugano, Asami Sanada as Reisuke Hojo, and Hiromi Konno as Kamado Ueshita. That is a lot of names to track, and the show knows it. It kills people.
A Death Match Built on Personality
The mechanic is the smartest thing here. Every device is tuned to its owner, so the game is not a straight fight. It is a fight between temperaments. A diary built for one kind of person fails the moment that person acts out of character. The premise forces the cast to confront themselves, and the show gets real mileage out of that.
The genres listed are Action & Adventure, Animation, Drama and Mystery. The mystery is the weakest of the four. The action is serviceable. The drama is where the series earns its keep, because the drama is about people who cannot trust their own instincts.
Here is the run as the source gives it:
| Block | Episodes | First aired | Last aired |
|---|---|---|---|
| Season 1 | 26 | 2011-10-09 | 2012-04-15 |
One season, six months, 26 episodes. The show covers a lot of ground in that window.
What the Show Gets Right, and What It Fumbles
Three things work.
- The device mechanic, which turns personality into a weapon and a weakness at once.
- Yuno Gasai, who is the reason people still argue about this series years later.
- The pacing across 26 episodes, which rarely stalls.
Two things do not.
The cast is too big for the time it has. Twelve players plus supporting figures is a lot of ground to cover, and the roster includes Reisuke Hojo and Kamado Ueshita among the named players. The show has to keep moving, and it does.
The series leans on shock. A death lands harder when the audience has had time to sit with the person, and The Future Diary does not always give itself that time.
The Score
The Future Diary holds a TMDB audience score of 7.6 out of 10 across 502 votes. That number is fair, and this review lands in the same place.
The series is not a masterpiece. It is a high-concept thriller with a genuinely original hook, a memorable central pair, and a supporting cast it cannot fully service. The device gimmick is strong enough to carry the weaker episodes, and Yuno Gasai is strong enough to carry the show’s reputation.
What holds it back is discipline. Twenty-six episodes is the right length for this story, but the show spreads its attention too thin across 12 players. The best version of The Future Diary focuses on fewer people and lets the audience feel each loss. This version moves fast, hits hard, and forgets quickly.
That is still a recommendation. The premise is the draw, and the premise delivers. Anyone who wants a death match that is actually about the people in it, rather than the body count, will find plenty here. The show understands that a prophetic device is only interesting if the person holding it is.
