Kaiser's FGO Character/Servant 2
Literally the title. I've just gotten to the Goetia fight so any Servants in the story past that I have only interacted with in events and in summonings. I am biased towards that end. Also those that I don't know I rate based on my preference towards their historical/mythological story.
