Fate/stay night

A boy named Shirou Emiya, raised by a sorcerer following a fire that killed his parents, begins learning basic magic. After witnessing a conflict between two skilled Magi, he performs a spell beyond his level, unintentionally summoning a female knight to defend him. As a result, he is drawn into a contest called the Holy Grail War. In this conflict, seven Magi, known as Masters, each paired with a spirit ally called a Servant, compete for a powerful relic believed to fulfill any desire.
