Fate/Stay Night: Réalta Nua Fate
For the one who receives the Holy Grail, every wish comes true. The Holy Grail War. A great ritual in which the greatest sacred artifact, the Holy Grail, is materialized. There are two conditions to participate in this ritual: You must be a magus and a "master" chosen by the Holy Grail. There are seven chosen masters and seven classes of servants; beings resembling superhumans with incredible fighting abilities. There is only one Holy Grail. If you wish for a miracle, you must prove that you are the strongest with your powers. Emiya Shirou is a high school senior who learned rudimentary magic from his father and uses it to repair items. He becomes involved in the Grail War when he is attacked by a servant. When he is cornered, he somehow summons his own servant and manages to stay alive long enough to compete against the other masters.
