Kaeya is the Cavalry Captain of the Knights of Favonius. He is held in high regard by the people of Mondstadt — even with all his eccentricities and secrets. Kaeya uses the tall male model. 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. His visible eye is periwinkle with a diamond-shaped pupil.
