Now for this one, it was a toss-up between Caster or Rider (not F/Z one). And as the image above shows, I’ve went for Rider.
A silent, sultry servant that obeys that pathetically useless magi Shinji (if you’ve watched any of the fate series). For the first two branches, rider gets a raw deal. Where she is killed off pretty early and has no development or much screen time what-so ever. However (and I see this with much glee :D) she gets plenty of screen time in the up-coming movie heaven’s feel. Rin and Saber get the most mention, as it is plain obvious they are the main leads. But I do feel that caster and rider get shafted to the side.
