Kiritsugu Emiya

"And there you go. You heard her, Iri. Our Heroic Spirit over there considers a battlefield to be better than Hell. What a joke! A battlefield is Hell itself! There's no hope to be had on one. There's nothing but unspeakable despair! Just the soulless crime we call victory, paid for by the pain of the defeated. But humanity has never recognized this truth. And the reason is that in every era, a dazzling hero had blinded people with their legends and kept them from seeing the evil of bloodshed they bring. Humanity's true nature has not taken a step past the Stone Age!"

- Kiritsugu Emiya, revealing his views on war Kiritsugu Emiya is the main protagonist of the light novel/anime series Fate/Zero(although as the story is told from seven different perspectives, this status is fairly debatable) and the Master of Saber during the Fourth Holy Grail War. Being an Anti-Hero, he has several personality traits commonly found in villains, such as ruthlessness and a belief that there are no rules in battle beyond doing whatever is necessary to win. However, he is very tragic and not particularly proud of his methods, merely seeing them as a means to an end.

He is voiced by Rikiya Koyama in the Japanese version of the anime and Matthew Mercer in the English version, the latter of whom also voices Alvin.

About
He is mostly an anti-hero, but does commit several villainous acts throughout the series. These include blowing up a hotel, manipulating people(having Kayneth Archibald El-Melloi and his fianceé killed after promising to let them go being the most heinous) and refusing to acknowledge Saber's existence, to the point that he refuses to even talk to her, for no actual good reason at all. He justifies his actions by saying that the battlefield is no better than Hell on Earth and so he believes that all forms of killing are the same. He also blames the Heroic Spirits for covering up the truth of war with their legends and that because of them, humanity's true nature hasn't taken a step past the Stone Age, implying a degree of misanthropy.
