Fate Stay Night Unlimited Blade Works (x reader)

As a child (Y/n) has never met her mother or father, wishes to obtain the grail to find out the people involved, this gets her involved into the Fifth Holy War as a master and summoning Lancer as her servant. Without the Grail, (Y/n) knows she can't find out who killed her mother without getting help from Gilgamesh who was a servant for an enemy master. Can she find closure for her family and will she experience something else along the way? Find out on the next Dragonball- ah wrong anime- Fate Stay Unlimited Blade Works.
It somewhat follows the plot line of FSN UBW with more or less editing on my part I plan to create many endings as many people aren't going to be happy if MC-chan is just an emotionless girl who can't love anyone other than her parents
