Fate Zero isn't even remotely harem. The MC is married with a kid and all. There are a lot of characters, male and female, but I don't see how that's a problem... But whatever floats your boat man.

Best one I have seen so far

i'm never ever watching fate zero since it kinda harem and too much different female and male protagonist. but when i saw i think ova that saber working as waiter and how somehow gilgamesh kinda out of character , it kinda cute but since someone said that opposite to the original one but still gilgamesh interest in saber was true in ori. well for now i will only see h ver since i'm not that interested in it original anyway...

That cute bush
