Mondaijitachi is a fun anime and Izayoi, for all of his unexplained(or poorly explained) overpoweredness, is a very likeable and fun character - however as far as story goes it simply can not compare to the giant that is Nasuverse and Fate/xxx story contained within. Fate/Zero /Stay Night, /Apocryha are all parts of a big world, and all of them are teeming with references to both real historic personalities as well as myth protagonists. The most basic premise of Servants states that they are Heroic Spirits - that is people who distinguished themselves in past(King Arthur, true Assassin, Alexander the Great...), myths, which apparently are real in this world,(Heracles, Gilgamesh, Medusa, Medea..., present(None revealed), future(Shirou) and even man-made stories(fake Assassin). You can not consider those characters as disconnected from their real world counterparts, this is simply being stubborn for no reason. One of good things about Fate/ series is that it sends you on bouts of tangential learning - you hear a bunch of historic names and, if you want to understand the story in full, you need to either already know them or look them up and learn something.
