An accomplished swordsman and a strategic thinker in the Knights of Favonius, rumored to hail from beyond Mondstadt. Kaeya is an outwardly confident and charming individual with a flair for drama. He is sometimes seen as overly laid-back and even lazy, but he takes his work seriously. He has a tanned complexion and navy-blue hair with streaks of lighter blue, accompanied by a waist-length lock of hair that begins at the base of his scalp on the back of his head at the left. Wears eyepatch.
