Setting
Fate/Zero takes place 10 years prior to the events of Fate/stay night, detailing the events of the Fourth Holy Grail War in Fuyuki City. Originally founded by the Einzbern, Tohsaka, and Matou families, the war involves seven Masters and seven Servants under seven classes: Saber, Lancer, Archer, Rider, Caster, Assassin and Berserker.

Plot
After being defeated in three successive wars for the Holy Grail, the Einzbern family is determined to win the next one at any cost and elects to hire the notorious Magus Killer, Kiritsugu Emiya, to become their representative in spite of his reputation as an unconventional and ruthless hitman. For the next eight years, he prepares the war in the Einzbern stronghold while unexpectedly forming a family with Irisviel von Einzbern, who is to become the vessel for the Grail, and their daughter, Illyasviel. However, Kiritsugu must contend with six formidable opponents, all participating in the war for their own reasons.

From one of the three founding families, the magus Tokiomi Tohsaka wants to achieve Akasha through the Holy Grail, receiving support from the priest Risei Kotomine and his son, Kirei Kotomine, who is also unexpectedly a master in the war. Unlike Tokiomi, Kirei has no direction in life and soon sets his sights on Kiritsugu as an answer to the frustrating lack of meaning in his life.

Meanwhile, Kariya Matou becomes a Master after learning Tokiomi's younger daughter, Sakura, was adopted into the Matou family. In hopes of saving her from suffering at the hands of Zouken Matou, he agrees to win the Holy Grail in exchange for her freedom to return to her family.

After learning of the war and taken by arrogance, Clock Tower magus and lecturer Kayneth Archibald El-Melloi decides to join the battle to increase his own prominence within the Mage's Association. However, his dismissive attitude towards the radical theories of his student, Waver Velvet, drives the young man to steal Lord El-Melloi's artifact and participate in the war in order to force the Mage's Association to recognize his genius.

When a seventh magus fails to answer the Grail's call, a serial killer named Ryuunosuke Uryuu is chosen to become the final Master in the war. Seeking exciting new ways of killing people, he winds up summoning a Servant from an occult book and proceeds to commit as many unusual murders as he can with the help of his Servant.

As the war begins, only one will emerge victorious.

Despite his difficulties with Rider's overbearing nature, Waver and his Servant form a strong and sincere relationship.


 * Maiya Hisau (久宇舞弥)

 * Kayneth Archibald El-Melloi
 * Master of Lancer, a nobleman from the Magus Association. His artifact is stolen by Waver Velvet, but he manages to summon Lancer anyway. While he holds the command spells for Lancer, the energy to materialize the Servant is maintained by Sola-Ui.

 * Sola-Ui Nuada-Re Sophia-Ri
 * The daughter of the head of the spiritual evocation division. She is engaged to Kayneth as a result of a strategic marriage arrangement and the decision of her family to entrust their crest to her brother instead. However, she is coldhearted and does not reciprocate Kayneth's love for her; instead, she becomes infatuated with Lancer, who in turn does not reciprocate her feelings and regards her only as his Master's wife.


 * Risei Kotomine (言峰璃正)
 * Kirei Kotomine's 80 year old father, a priest in the Church, the regulator of the 4th Holy Grail War. He is a friend of Tohsaka Tokiomi and actively supports him. While he is proud of his son, who has demonstrated himself to be a perfect heir, Risei fails to understand Kirei in any sense.

Servants Servants participating in the Fourth Holy Grail War and their true identities include the following.


 * Saber
 * King Arthur, the same character from Fate/stay night. Known as the King of Knights, she maintains a high code of honour. Though she and Kiritsugu are Servant and Master seeking the same ultimate goal of peace, their differing ideological perspectives result in a strained relationship where Kiritsugu does not directly acknowledge Saber.


 * Archer
 * Gilgamesh, a rogue servant in Fate/stay night, the King of Heroes. He dislikes the presence of Saber and Iskander in particular since they were kings like he was. Much to Tokiomi's displeasure, Gilgamesh has difficulty acting covertly, especially when his considerable pride is wounded.


 * Lancer
 * Diarmuid Ua Duibhne, a Servant with two Noble Phantasms: Gae Buidhe - Golden Rose of Mortality and Gae Dearg - Crimson Rose of Exorcism, which can counter Saber and Berserker's abilities.

 * Rider
 * Iskander (Alexander the Great), the King of Conquerors, who desires to defeat Saber and Lancer in particular. Has several Noble Phantasms, the first of which is Gordius Wheel - Wheel of Heaven's Authority, which summons an ox-drawn chariot when Iskander slices the air with his sword. His eccentric and overbearing personality along with his incredible abilities creates difficulties for his Master and their opponents.


 * Caster
 * Bluebeard (Gilles de Rais), a Servant who derives pleasure from first providing his victims a moment of relief before terrorizing them and then killing them. Expresses an interest in Saber because he has mistaken her for Jeanne d'Arc, with whom Bluebeard has an infatuation.


 * Berserker
 * Lancelot du Lac (previously known as the Black Knight), a Servant who possesses the ability to use practically any object as a Noble Phantasm, allowing him to match Gilgamesh in combat. His madness has reduced him to mindless, though dangerously skilled, fighter. Despite his insanity, he is still able to instinctively recognize Saber.

Development
The project began when Nitro+ writer, Gen Urobuchi, met with Kinoko Nasu and Takashi Takeuchi. Takeuchi suggested a prequel proposal to Urobuchi, who had been experiencing writer's block while attempting to write a happy story. Urobuchi, who was known for his tragic stories, agreed to become the writer for the project. Though Urobuchi is the writer for the series, the project was supervised by Kinoko Nasu, who looked over the draft for the new characters and the plot.

In Fate/hollow ataraxia, there was teaser poster of Fate/Zero in one of the background images. It is unknown if the novels were in development at the time.

Light novel
The first volume was released on December 12, 2006, and the fourth and final volume was released on December 29, 2007.
