"I'm determined to become a hero of justice for Sakura." To save the girl...to enact the justice he's chosen... The young man will no longer turn a blind eye to the truth. Mages (Masters) and Heroic Spirits (Servants) work together in the battles of the Holy Grail War...a fight for an omnipotent wish-granting container called the Holy Grail. However, this war has become horribly twisted. A young woman named Sakura Matou, with the sins she has committed, drowns in the murky darkness.
