The Holy Grail is a powerful, ancient relic capable of granting any wish the beholder desires. In order to obtain this power, various magi known as "masters" summon legendary Heroic Spirits called "servants" to fight for them in a destructive battle royale—the Holy Grail War. Only the last master-servant pair standing may claim the Grail for themselves. Yet, the third war ended inconclusively, as the Grail mysteriously disappeared following the conflict. Many years later, the magi clan Yggdmillennia announces its possession of the Holy Grail, and intends to leave the Mage's Association. In response, the Association sends 50 elite magi to retrieve the Grail; however, all but one are killed by an unknown servant. The lone survivor is used as a messenger to convey Yggdmillennia's declaration of war on the Association. As there are only two parties involved in the conflict, the Holy Grail War takes on an unusual form. Yggdmillennia and the Mage's Association will each deploy seven master-servant pairs, and the side that loses all its combatants first will forfeit the artifact. As the 14 masters summon their servants and assemble on the battlefield, the magical world shivers in anticipation with the rise of the Great Holy Grail War. [Written by MAL Rewrite]

In the world of Remnant, humans and Faunus—human-animal hybrids—carry on their everyday lives despite the omnipresent threat of the monstrous Grimm. Dedicated Huntsmen and Huntresses battle Grimm with both customized weapons and their own "Semblances," unique abilities derived from the energy of one's soul. Some warriors also utilize a crystallized energy propellant, "Dust," to bestow their weapons with elemental properties. In this dangerous line of work, rigorous training is required to stay alive. To that end, each of Remnant's four Kingdoms have established schools to properly groom children holding aspirations of becoming licensed Huntsmen. At Beacon Academy in the Kingdom of Vale, a promising group of future Huntresses make their debut as Team RWBY. Ruby Rose, Weiss Schnee, Blake Belladonna, and Yang Xiao Long each come from different backgrounds and often butt heads as a result. However, when they cooperate, they are a formidable force who have even attracted the attention of Beacon's headmaster Professor Ozpin. Alongside fellow students such as those in Team JNPR, the young prodigy Ruby and her friends engage in adventures which pit them against an extremist Faunus group known as the White Fang. Every explosive encounter also brings them closer to the true villains orchestrating conflicts from the shadows.
