Fate/Prototype

Fate/Prototype is a reimagined version of Kinoko Nasu's original version of Fate/stay night.

Setting
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).

Plot
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.

Development
The original version of Fate/stay night, now called Old Fate (旧Fate) and Fate Origin, was a novel that Nasu wrote during high school, eventually being vastly redesigned as a visual novel to suit the target audience. They were reluctant to completely abandon many of the "original charms" that were discarded, and they had wished to utilize them somehow with each passing year. Twenty years after originally being penned, they decided to make use of the release of Carnival Phantasm, discarding other proposals like Princess Arcueid VS Saber Lily or a scene from Tsukihime 2, to "just once, return to the original" for the company's belated tenth anniversary.

They decided to frame the animation like a movie trailer, utilizing the the best parts and still telling the story properly. Nasu feels that the main idea of the work was in the style of an ‘80s romance, “A story of revolutionizing the world”, and took great interest in returning to the work. The large difference in obtaining the Holy Grail from the original to the final product in Fate/stay night can be said to represent the changing trends of the period.

Adaptations
It was originally released as a twelve minute anime segment released with Carnival Phantasm Season 3, and included the Prototype Material databook. There are no current plans to develop the work into a full story. The comedy Fate/Prototype Drama CD was included with the Comptiq December 2012 issue.

Light Novels
Fate/Prototype: Fragments of Blue and Silver (Fate/Prototype 蒼銀のフラグメンツ) is a currently serialized prequel light novel series written by Hikaru Sakurai and illustrated by Nakahara. The name comes from the colors of Saber's armor. While Sakurai has discussed some elements of the story with Nasu, he is not a primary supervisor like with other Fate stories. She created the six new original Servants herself, seeking out advice on some elements.
