In Fuyuki City, the Fifth Holy Grail War is about to commence a lengthy battle of blood, death, and misery.

Summoning her Servant known as Archer, Rin finally sets foot into the battle.
Discovering that one of her acquaintances, Shirou Emiya, is drawn into the war as well, Rin offers to form an alliance for the time being.
