Archer [Servant]
Heroic Spirit of the bow. The basic abilities of these Servants tended to be low, but they compensated with Skills and Noble Phantasms.
The Archer in this story was no exception, he engaged in combat with unidentified Noble Phantasms.
A thoroughly cynical pragmatist... but even so, he had an oddly childish personality that no one could hate.
His real identity was ???. He was such an important character in the story, you could call him the shadow protagonist. Half of Fate could be called his story.
At the beginning of the game, Archer claimed his memory was confused due to incomplete summon. This was half-truth.
On the night of the summoning, Archer assessed the situation and deduced the current circumstances. He believed that he would have the opportunity to achieve his goal.
At the instant Rin introduced herself, Archer believed the girl who summoned him was "Tohsaka Rin" (not due to his memory being confused, but the name Tohsaka Rin being worn off).
At that moment, Archer recalled like a jolt of lightning:
"-------Rin. Ah, that's the name------"
Archer murmured this under his breath at that time. It was truly from his heart and filled with much endearment close to insanity.
... There were much foreshadowing in the story besides this instance, but they were all limited except for the post-Saber vs. Berserker narration.
Due to the rebound of some magecraft, his skin turned dark... something like that.
