Akechi has shaggy, neck length brown hair with bangs and reddish-brown eyes. He wears a tan peacoat with black buttons, striped black and white tie, black pants, black gloves and black loafers. His casual winter outfit consists of a white long sleeve shirt with flaps under a blue argyle sweater vest, beige pants and brown shoes. In public and with all of his relations, Akechi appears to be well-mannered, friendly, humble and charismatic. His achievement of being a high-school detective, coupled with his handsome features, makes him highly popular among the general public and he is commented to be "The Second Coming of the Detective Prince." His intelligence and smooth-talk earned him enough trust from the police to conduct his own investigation despite his young age.
