OF COURSE FATE ZERO!!!
It's been years since I last watched this.
Well, I am not exaggerating but I didn't watch the sort of
spin-offs of it,
I only stared... I mean drooled at Fate Stay/Night
Too bad no Shirou Emiya and Rin Tosaka on the list
but this will open up our minds to what really happened 10 years
before... the fight over the holy grail
