Overview
The year 2029.

In a world where science and magic co-exist peacefully and bring about numerous advancements aimed to safeguard and perpetuate the world and humanity, people born with aptitude known as Magic Circuits are capable of utilizing special tools known as Class Cards to summon the power of legendary figures from mythology and folklore. These powerful beings are placed in seven standard classes: Saber, Lancer, Archer, Rider, Caster, Assassin and Berserker.

A hundred years ago, during the second World War, the Class Cards were used extensively, causing a chaotic reaction inside the Holy Grail, which causes rogue Heroic Spirits to manifest from their respective Class Cards.
