这里是故事的原点（zero）—— 为了获得圣杯能实现奇迹的法力，七个魔术士召唤出七人的英灵，展开了一场直到剩下最后一个人为止的终极战争----圣杯战争。 之前三次没有结果的战役不足以让这场战争结束，第四场战役如今有如弦上之箭，一触即发。 寄托着必胜的信念，魔术师们来到了被称作“冬木”的战场。但是在他们当中有一个人却不知道自己是为何而战。他叫——言峰绮礼。 命运的引导让绮礼逐渐失去了自己的判断力，他不明白为什么自己会被授予令咒。但是，命运很快地安排他遇到了一个命中注定的宿敌——卫宫切嗣。 这个男人想要得到圣杯的欲望比任何人都要强烈，使用的手段也是最残忍的。 在《Fate/stay night》中仅略有提到过的，十年前发生的“第四次圣杯战争”的真相。士郎的养父，凛的父亲，以及年轻气盛的言峰绮礼是如何参与这场战争的，真相即将浮出水面。
