Fate/Stay Night: Archer
The Servant of Tohsaka Rin in the 5th Holy Grail War. He is well adept in bare-handed fighting, armed combat, Magecraft and even performing housework. lol
He possesses a personality that is thoroughly cynical, but at the same time devoted and even a little childish to the point that it makes him hard to hate.
He doesn't lie, but he does keep secrets. He is sarcastic, but it's how he gives advice.
A character who did not do much in the Fate/stay night series but whom I remember fondly.
