Fate: Break Dawn

Counter Guardian Emiya is a man of many regrets. Among them, the fact that he wasn't able to save his Saber when he was a boy continues to haunt him to the end of days. Now, however, a chance has mysteriously appeared to change that result. And being the practical man he is, he will not hesitate to seize it. But still... why in Alaya's name is Artoria his new Master in this world?
