Shielder-class, and here to provide her protection and aide to all inhabitants of Chaldea. Master has emphasized she focus on her bonds with other Servants; this has made her relatively unable to deny requests, be them innocent or otherwise.
Mash is a mysterious, kind-hearted girl. She refers to Ritsuka Fujimaru as her senpai even before Ritsuka becomes her Master, feeling that something about them is especially easy to relate to. However, that smile belies a deep sorrow and resolve that has accepted her fate as a person with a set life-span since day one. As she has spent nearly all of her life in an isolation chamber within Chaldea, she is somewhat naïve and lacking in worldly experience. Despite this, she knows about a wide variety of subjects due to her education via Sheba, and she is especially knowledgeable about historical figures. Mash was initially designed to have no personality whatsoever in order to facilitate the Demi-Servant creation process, but Roman encouraged her to begin expressing her own opinions, allowing her to begin forming a sense of self.
