the beauty of fate/zero, is that there really isnt a super main character. Its more of a conflict of morals and philosophies from different masters, and how these clash with one another. The plot is very vague, (which is to win the holy grail), it is because of this vague plot, that the writer can add in so many varying stories from different masters. thats what makes this anime very interesting and unique, it is the ambiguity of the story and outcome, which deviates from a typical storyline formula. I hope you guys enjoy the later episodes tooπππ
