This story is a MLP interactive crossover of Fate/Stay Night. Storm lost his parents in a fire when he was young and was later adopted by a mage by the name of Doctor Whooves. Although he was full of admiration for his adopted father and yearns to become a hero of Justice, Storm has limited powers and was unable to become a strong mage like his father. That is until one fateful day, he was drawn into the Harmony Grail War and had to summon a female "Servant" known as Saber in order to protect himself. It turns out that the Harmony Grail War involves a series of battles among powerful mages to fight for the possession of a relic that will grant one's wishes, the Harmony Grail. There are altogether seven "Masters" who can summon their respective "Servants" from different classes known as Saber, Archer, Rider, Berserker, Lancer, Caster and Assassin. These "Servants" have to hide their names in order not to reveal their weaknesses to the enemies. The story revolves around Storm and his entanglement in the Harmony Grail War.
