You'd been born with the abilities to summon and control multiple servants in a great holy grail war just like this one...but what after? Were you truly just a tool to be used and disposed of? You were motherless and fatherless, no family you knew of. You were on your own...that is, until you met Shirou. You soon become a Master of red, fighting in the great holy grail war. Will your heart fall with the man you know as your best friend, or with a legendary hero?
