Kaeya, tall with tanned skin, flaunts navy-blue hair with lighter streaks. His signature is a waist-length lock cascading from the base of his scalp on the left. Concealing his right eye is a gold-trimmed black eyepatch, partially veiled by his bangs, hinting at an underlying scar. He dons a fur-collared half-cape over a revealing white-collared blouse, paired with dark trousers and knee-length boots. Completing his look is a blue earring adorning his left ear.
