Keigo is a man of average height with a slim and narrow build. He has feathery, ash blond hair that is swept messily backward, with some of the front tufts sticking up in arcs above his head. His eyebrows are notably thick, having a similar texture as his hair, and he has faint stubble on his chin. Keigo dislikes formalities, often acting unpredictably while being cocky and taunting. He acts nonchalant and jokingly submissive since he does not care about social status or recognition.
