Fate/Prototype

Fate/Prototype is a digest version of Kinoko Nasu's original version of Fate/stay night that he developed as a novel in high school before completely redesigning it as a visual novel. It is a twelve minute anime segment released with Carnival Phantasm Season 3, and included the Prototype Material databook. There are no current plans to develop any more pieces of media based on the concept.

Plot Overview
The storyline of Fate/Prototype takes place eight years after the tragic Heaven's Feel. Here, the Holy Grail is still the so desired object. However, the darkness under this so called "Grail" is revealed while the characters proceed to fight against each other in order to win.

Ayaka Sajyou is the last member of her family, and tries to live normally without any relation to the past or with the actual war. However, her destiny was sealed since she was the younger sister of the prominent Manaka Sajyou, who was murdered during the war. She could still remember the last thing her father said before his death "You have no choice but to enter into the Heaven's Feel".

On the eighth anniversary of the death of her family, Ayaka is pursued by a mysterious man with vicious creatures, but just in time, a holy radiance brings a warrior that saves her. Now, Ayaka has no choice but to enter into the battle.

Characters
The system of the War and everything else is much like that from Fate/stay-night in some points, but unlike the produced project, the Prototype version has Masters that possess "Master Degrees", which are named following the angelic hierarchy starting from the 7th Order and up (so Princes, Powers, Virtues, Dominions, Thrones, Cherubim, Seraphim).


 * Ayaka Sajyou (沙条綾香), is the previous version of Shirou Emiya. She appears to be a very insecure person, traumatized after the previous Holy Grail War after her father and sister died because of it, and not willing to join the current one. On the anniversary of her father and sister's death she is pursued by Lancer much like Shirou. She is also saved at the last moment by her Servant, Saber. Her position as Master is under The Seventh, Princes.
 * Saber, The First, is the previous male version of the female Saber. He responded to and accepted the summons of Ayaka in time to save her life from Lancer who had been pursuing her. He shows the sense of values of a matured man, as well as a strong sense of justice.
