マシュ・キリエライト

Mash is a Demi-Servant human fused with the Servant Galahad. She herself initially does not know the identity of the Servant fused with her. In the year 2000, Mash was created from artificial fertilization and genetic editing. She is actually a Designer Baby, a magus genetically engineered under the orders of Chaldea's late director, ‎Marisbury Animusphere, to be a prime vessel for a Heroic Spirit's soul. The project aimed to control the powers of Heroic Spirits by binding them to a compatible mortal vessel in order to produce Demi-Servants. In 2010, Chaldea perform their second Heroic Spirit summoning. While the project succeed in summoning and binding a spirit to Mash, the spirit failed to awaken. Galahad decried Chaldea's brutal experiments, but remained in the world to keep his host alive. After the research team deemed the project a failure, Mash was left to Chaldea's care. However, due to being a genetically engineered organism not dissimiliar to a Homunculus, her life-span was set since her conception. She was given eighteen years to live and while she was aware of this fact, she kept it a secret between herself and Dr. Romani her physician. By the start of the story, Mash has already lived sixteen years of her life giving her a mere two years left, at best.
