The Holy Grail War, a bloody tournament that revolves around an all-powerful treasure that will grant its wielder a miracle, the Holy Grail. To be granted the right to wield it, seven magi must each summon their own heroic spirit and engage in a battle royal to eliminate the unworthy and become the last man standing.

He became angry at Tokiomi for allowing Zouken to adopt his own daughter, Sakura, knowing what cruel fate awaits the little girl at the old man's hands.

Kariya's Servant. A heroic spirit that is granted enormous strength at the cost of sanity. This Servant-class is the hardest to manage as it requires a lot of magical energy to maintain. He can wield anything he touches as his own weapon.
Rider's Master. A member of the Magus Association, Keyneth's apprentice and future El-Melloi II. He stole his mentor's catalyst for summoning so he could summon the Servant himself and join the Holy Grail War to prove himself and for his genius to be acknowledged by the Magus Association.

Lancer's Master. Engaged to Sola-Ui though a strategical marriage arrangement. Waver's mentor. A member of the Magus Association and hailed as a genius. He originally intended to summon Rider by using a catalyst but after Waver stole the item, he summons Lancer instead.
