Akashi Seijuro has a rather small stature for someone who has captained the Generation of Miracles, at only 173 cm tall and weighing 141 pounds. He has spiky bright crimson red hair and large eyes with vertical pupils the same color as his hair. Akashi's eyes change based on his personality: in his normal self, both his eyes are red-maroon, whereas the "other" colder and crueler Akashi has heterochromatic eyes, with the right eye being red and the left being yellow/orange.
